o be perfectly honest I haven’t a clue how the UN goes about deciding what does or doesn’t merit having an international year

to itself. It might involve Machiavellian machinations and political manoeuvrings, vested interests jostling for their turn in the limelight. Or that might be fanciful, and it is in fact a benign process, and we can take at face value the aspirations in their prospectus to educate and promote the betterment of humankind.

Whatever the process and objectives, the latest subject to be selected is light. In case you haven’t heard, and worryingly quite a few people haven’t, 2015 is the Unesco International Year of Light (see p20). Which ought to be a good thing. But it seems that their view of what light is about and ours is somewhat at odds. They are largely seeing it in terms of physics, nanophotonics and quantum optics, for instance, and therefore the current agenda doesn’t consider many of the aspects of lighting that we would consider important and salient to the way humankind lives, whether it is the quality of the lit environment in our workplaces and cites, or the use of kerosene in the developing world. There is time to put that right and it is an opportunity for professional lighting bodies to give themselves prominence by taking the lead with government. It’s also clear that whatever Unesco thinks it’s about, the lighting profession should use the banner for all it’s worth anyway – it’s a significant peg to hang a message on, and an ideal opportunity to get people’s attention. Having seen the latest hysterical tripe about LEDs in the Daily Mail last month – ‘Coming to a street near you: the lights that keep you awake and could make you ill’ was the headline in case you missed it – the education process can’t start soon enough

LIA launches strategy document for lighting sector The LIA has launched a Lighting Sector Strategy document in conjunction with the Department for Business, Innovation and Skills.

It looks at all areas from R&D through to the supply chain and the enforcement of standards.

The aim is to examine ways in which the industry can become more coherent and united in its strategy, and how it can exploit technological development to grow British business both at home and globally.

‘The key is having a healthy, competitive and sustainable UK lighting industry which can respond to change with agility,’ says The Rt Hon Michael Fallon MP, Minister of State for Business and Energy, in his foreword to the document.

‘This strategy and its developing plan, coupled with the industry and government working in partnership, is designed to meet those opportunities

Glowing report The Dutch pilot project to use photoluminescent paint to create ‘glowing lines’ along a stretch of the N39 highway in Oss, around 100km south east of Amsterdam, officially opened last month.

Once the paint has absorbed daylight, it will emit a green glow at night for up to eight hours, theoretically making street lighting unnecessary.

A collaboration between interactive artist Daan Roosegaarde and Dutch civil engineering firm Heijmans (see Lighting Journal January 2013), this initial trial covers a 500km stretch of the route and will operate for five years.

‘If we put this technology on all unlit roads that would be a lot of kilometres and it would be a big investment so if safety

and grow the UK lighting sector in a sustainable way,’ continues Fallon.

The document also looks at communications, and ways of raising awareness of various government mechanisms and incentives that the lighting industry can take advantage of, such as Patent Box and R&D tax credits.

‘A broad range of policy outcomes, initiatives and support mechanisms is already on offer but it is unlikely that the UK lighting industry is fully aware of all its options,’ says the document. ‘Moreover, it is difficult for government and its agencies to communicate these clearly to such a wide range of companies.’

Energy efficiency and sustainability are also high on its agenda and the document moots the setting up of a Green Tech UK brand, similar to the US governmentbacked Energy Star programme

improvement is the target then we need hard evidence about how this compares to what we already have and to back up any safety claims,’ said Dutch Minister for Infrastructure Melanie Schultz Haegen when visiting the project.

Previous studies have shown that ‘luminescent road paint would be unsuitable for use in this country,’ according to the UK Highways Agency, which said it was watching the trial in the Netherlands with interest.

If luminescent road markings were to figure in its design standards, certain factors would have to be taken into account, said the HA, including how far in advance road markings could be seen, how skid resistant they were, how visible they were during the day and how they would perform in winter when there are fewer hours of daylight.

that aims to help businesses and individuals protect the environment.

‘The LIA is convinced that to ensure the UK lighting industry makes the most of the current lighting revolution, we need industry and government to be aligned in terms of strategic objectives,’ said Peter Hunt, the LIA’s chief operating officer. ‘We actually want much the same thing – growth, jobs and exports, which convert to revenue, and energy efficiency, which reduces energy costs and the need for more power stations.

‘The strategy document lays out a roadmap,’ he continued, ‘but to succeed and deliver it will need the support and engagement of the lighting industry.’

Hampshire goes for CMS Hampshire County Council has installed the Mayflower central management system for more than 100,000 of its street lights.

According to SSE Contracting, which owns Mayflower Complete Lighting Control, it is one of the single largest remotely monitored and managed street lighting systems in the world. Installation began in 2010 through the Hampshire County Council Street Lighting Private Finance Initiative (PFI) and is set to cover around 150,000 lights by 2015.

Prior to the installation, Hampshire’s street lighting was consuming around 50m kW hours of energy a year. This will be reduced to 34m kW hours by 2015, according to SSE, primarily through the use of variable light control.

CO2 emissions will be cut by around 4000 tonnes. Hampshire’s upgrade programme involves 78,000 lighting columns and 51,000 lanterns.

Media picks up on LED lighting complaints The BBC and the Daily Mail were among the media to pick up on the latest story of residents outraged by new LED street lighting.

Residents in Park Road, Chiswick, part of a conservation area in the west London borough of Hounslow, are complaining of sleepless nights because of overbright new street lights. The BBC report shows residents putting up blackout blinds and masking tape over their windows. There have also been complaints that the LED fittings are not in keeping with the character of the area and residents are worried that trees may be cut back to accommodate the higher columns.

Hounslow Highways, which installed the lights, say the brightness will be adjusted through the central management system that will be trialled in the area.

Statistics show switch off is unsafe, says AA Motorists are at greater risk in urban zones without adequate street lighting, according to new statistics quoted by the AA. In the past five years, night-time accidents in bad weather on 30mph urban roads have dropped by 15.6 per cent, according to the motorists’ organisation. However, in areas where lights have been switched off the reduction is only two per cent.

Accidents along 40mph built-up roads in the wet, snow or ice fell in illuminated areas by 21.8 per cent, but only by 5.2 per cent on roads where lighting has been switched off, says the AA. From 2007 to 2012, there has been an overall reduction in road accidents on lit streets of

19.6 per cent, but just 8.8 per cent where streets were in darkness.

‘Worse accident rates on roads with street lights turned off or not present is an insidious threat that has crept in literally under the cover of darkness,’ said AA president Edmund King.

‘Roads that are safe when lit can become unsafe with the lights switched off, but that is only shown when drivers, cyclists, bikers and pedestrians start to get hurt and killed. Some local authorities have changed their minds after casualties, but why did people have to become street light victims to prove the point?’

Lumicom CEO retires

Lighting For People, a new web-based platform designed to be the ‘go-to site’ for topical, highquality information on solid-state lighting was launched last month at Light and Building.

It is part of the EU-backed, 13-country SSLerate project, a three-year coordination scheme introduced last November that aims to accelerate the uptake of high-quality SSL technology in Europe. The platform ‘will provide the latest scientific findings on advances in human centric lighting and encourage green business development by means of open innovative collaboration,’ said SSL-erate, a 24-member consortium that includes UCL and Oxford University in the UK. ‘The Lighting For People platform represents a new model for connecting people, municipalities, lighting and business in order to make the best – and most informed – lighting decisions in sectors from elderly care and healthcare to education and beyond,’ it adds. www.lightingforpeople.eu

Ernest Magog, CEO of Lumicom, retired at the end of March after 32 years in the lighting industry.

Magog joined the industry in 1982 as director of the Lighting Industry Federation (LIF). His initiatives include the launch of the LIF Certification Courses and the revitalisation of the All-Party Parliamentary Lighting Group, as well as raising the profile of energy-efficient lighting.

He became CEO of the newly established Lumicom WEEE compliance scheme in 2005, educating stakeholders about the WEEE Directive while establishing an infrastructure to help companies achieve compliance.

‘There have certainly been challenges during the past 32 years but this is a fantastic industry to work in and I’ve enjoyed every minute of it,’ said Magog.

The survey also asked members what they thought of switching off up to 70 per cent of street lights between midnight and 5am. More than half (54 per cent) thought it sounded like a good initiative in terms of cutting costs and carbon emissions.

However, 78 per cent said local residents should be consulted before a switch-off policy was implemented. Only 47 per cent thought it would be a good idea in their own area.

Association to form the LIA has created a fantastic platform for Lumicom and the industry as a whole, and I have no doubt that I am leaving future progress in the hands of a very capable team.’

He is succeeded by Peter Hunt as the new CEO of Lumicom.

A shade less ordinary Any number of designers from Ingo Maurer to Philippe Starck have had a go at playing with the idea of the traditional table lamp. For anyone who appreciates a visual pun and thinks that conventional table lamps are a bit old coolie hat anyway, here is a Japanese designer’s take. In the off state it’s a bit unprepossessing, resembling a pole with what appears to be an empty lampholder, but when switched on the LED source projects the outline of a lampshade on to the wall. Designed by Tokyobased YOY, it comes in table and floor versions.

LETTER I firmly agree with David Milne’s suggestion of reviewing the electrical requirements in the National Annex of BS EN 12767 (Reducing the impact, Lighting Journal April).

Along with David I sit on the B509/10 committee of BSi, which feeds into the main European standard for passively safe street furniture and also the National Annex for the UK. Although I missed the original drafting of this standard, I volunteered so as to have an input on this annex, as I could not understand why such complex and costly disconnection systems needed to be specified.

In my opinion, these systems are probably the biggest bar to passive progress, as there are very large infrastructure costs necessary to add disconnection. I think if the annex, and hence passive wiring requirements, were made cheaper the take up of passive safety would be far higher than at present.

I think that there might still be a case argued for electrical disconnection systems in the rare instances where columns designed to shear clean off (usually NE or LE classes) are located in areas easily accessible to pedestrians. However, I do not believe such systems are necessary where pedestrians are unlikely to be in the vicinity or columns are the collapsing type (mainly HE class), which will remain wrapped around the electrical equipment in the base in exactly the same way that a traditional (nonpassive) column will.

During a collision, occupants of the errant vehicle are highly unlikely to contact electrical apparatus – they are already inside a Faraday cage able to withstand lightning strike and once the collision is over our emergency services are well used to dealing with damaged electrical equipment on the highway. No reasonable person is likely to interfere with a damaged column in the short interval between the collision and the emergency services arriving.

To conclude, I feel that the risk to occupants during a collision with a standard strength column is far greater than the risk of electrocution from passively safe columns.

Being able to then afford many more passively safe columns on our roads during these times of austerity far outweighs this risk.

NEWS IN BRIEF The ILP has introduced a new course for street lighting engineers.

Practical Street Lighting will cover three key areas: light meters and photometers, cable calculations and electrical know-how.

Three one-day courses are planned, in Glasgow (June), Rugby (August) and Edinburgh (September, subject to demand). The fee for ILP members is £195 and for non-members £340. Booking is on a first-come, first-served basis.

For more details go to www.theilp.org.uk/psl TMP (Traffic Management Products) has appointed Daniel Robinson as managing director. Robinson joins the company from the London Borough of Southwark, where he was the senior lighting engineer and former chairman of the Young Lighting Professionals.

The National Union of Students is running a campaign called Snap It Off, calling for photographic examples of poor lighting at colleges and universities to be posted on its website. ‘We have all seen it: outside lights on when it is sunny, lights on in locked empty rooms, too many lights,’ says the website. ‘Fed up with your university or college wasting energy? Now is your chance to take action.’ Meanwhile across the pond, rival candidates at Louisiana State University have made lighting a key in issue in elections for student president. http://snapitoff.nus.org.uk/ Lighting Research and Technology (LR&T) is to hold a symposium in July that will examine metrics in lighting.

It will examine the possibilities for improving the metrics used in both electric and daylighting design.

Speakers will include John Mardaljevic (left), Kit Cuttle (right), Mark Rea, Kevin Smet, Lou Bedocs and Peter Raynham.

LRT Symposium: Better Metrics for Better Lighting will be held on 15 July at the Roberts Building, UCL, Torrington Place, London WC1. For more information and to register go to www.sll.org.uk The Designers with Light Forum is a new element of the May Design Series at London’s ExCel, which also includes the Arc show. Among the speakers are Eoin Billings of Billings Jackson, who will dissect the designer’s role in redefining light, and Joost Hereman of Foster and Partners who, with Farhad Rahim of ChapmanBDSP, will look at hospitality lighting and its integration with architecture. Other speakers across the three days include John Bullock of John Bullock Lighting Design, Kevin Grant of Lighting Alliance and Matt Woodward, head of Havells Sylvania.

May Design Series will run from the 18-20 May at London ExCeL. To register go to www.maydesignseries.com Lucy Zodion is working with Enterprise to supply Kent County Council with part-night photocells. Tunbridge Wells and Sevenoaks were the first two districts to get the new photocells with work starting last December. Tonbridge and Malling followed in January and Ashford in February. The remaining eight districts will follow suit with the project completed by July 2014.

LIGHT Minded...

Where your lighting equipment comes from is as important as the provenance of your food or clothing, argues Jeremy Quantrill, managing director of Dernier and Hamlyn

These days many of us try to be more informed about how the food we eat has been produced and the clothes that we wear have been manufactured. But can the same be said of the way that lighting is specified and purchased? If you have responsibility for procuring or designing lighting, do you think about where it has been produced and what that means for the people involved as well as for the wider UK economy?

As a lighting manufacturer that has been around since 1888, we are clearly keen to promote the ‘buy British’ message.

However, even we acknowledge that sometimes for various reasons we or other British manufacturers may not be the best solution to your lighting needs. And we grudgingly accept that.

But what we do object to is companies that purport to be British manufacturers which in actual fact only assemble parts made overseas, or worse still, bring in complete light fittings from overseas, make a minimal change and put a sticker on them that pretends they were made here.

Thankfully we live in a democracy where no one is forced to buy their lighting from any particular suppliers. But all purchasers and designers should be able to make informed choices based on true and reliable information rather than being duped by companies making false claims.

Making a conscious effort to work with UK manufacturers whenever it is possible to do so has an impact on the state of the nation by safeguarding jobs, which means that these people have money to spend, increasing the likelihood of new and refurbished buildings needing the services of designers and lighting companies. So it’s a win-win situation for all involved.

Added to that the Made in Britain brand is extremely strong in certain parts of the world so it’s not about being parochial – it’s about knowing what suits your clients and your business, but in a way that is honest and truthful.

Then there is the control that working

Lighting Journal May 2014

with UK manufacturers gives you. Many of the projects we work on are complex and it is only by sitting down with the designers, and sometimes involving the clients too, that we can develop solutions that meet their aesthetic, environmental and legal requirements.

And while for some contracts it may be possible to make do with off-the-shelf lighting from an unknown manufacturer that may or may not have dubious sourcing

All purchasers and designers should be able to make informed choices based on true and reliable information rather than being duped by companies making false claims ethics or employment practices, we strongly believe that this process is worth greater consideration of the wider implications of your buying decisions. Aside from anything else this has a bearing on the issue of sustainability and establishing what is known as corporate social responsibility, a consideration that is quite rightly rising up the agenda.

So it’s up to you. Maybe this has made you stop and think, and encouraged you to reconsider whether ‘made in the UK’ can mean that just some elements of the lighting you are buying can be put together here. Or whether it really should mean that it is actually produced here and it’s your responsibility to ask questions and put suitable checks in place.

Opinion

LIGHT Hearted Dave Burton, technical director of Fifth Dimension Associates, on when the Lighting Fairy turns round to bite you This is slightly wicked but I have to say that what I really love about lighting is its unforgiving ability to catch out the unwary, myself included.

I’ve lost track of the number of times that what should have been a straightforward design project turns out to be the job from hell.

And when that happens – which it does with regularity – the reasons are almost always assumption, lack of information and someone in the process thinking lighting’s a doddle and that anyone can do it. Even worse, there’s the ‘leave that to the engineers, they know best’ approach and relegation of lighting to the late phases of a project when the options are limited.

Although I am primarily an engineer, I know my limitations and how far I can push my aesthetic abilities. The Bartlett course opened my eyes to the side of lighting which you can’t do by numbers and it’s a great shame that more engineers don’t get exposure to these aspects.

While there are many engineers who create fantastic lighting designs, better education, which covers both the technical and aesthetic aspect of lighting, is so important. So many designs that tick all the boxes for illuminance tables in standards end up looking dreadful, and yet just as many that have never been near a ‘lux plot’ are uplifting and perfectly effective in terms of visual performance.

We must strike a balance, making sure that both designers and engineers have an input to more lighting schemes so that the risk of getting caught out is reduced. I doubt that we’ll ever eliminate that risk totally, though, which is what makes the profession so interesting.

But rest assured, when you get it wrong and the Lighting Fairy turns round to bite you, there will be a wry smile on my face, because I’ve been there too.

Colour saliency

Hue and eye In an edited version of her Bartlett MSc dissertation, Elena Krylova examines colour saliency in the night-time environment and its relevance to lighting design

O

ur everday environments are visually very complex, containing masses of information that attracts our vision selectively at different times.

Sometimes we focus on a particular object(s) or part of it, or we can be attracted by a specific feature of the stimulus, such as its colour or its brightness.

The term salient, or visually conspicuous, refers to stimuli that attract attention to their location in the scene (Itti, 1998). There have been a number of research studies examining the factors that influence the conspicuity of an object: why some objects are easily noticeable while others are not (Duncan and Humphreys, 1989; Moraglia, 1989; Nothdurft, 1992).

A general observation is that an object that stands out from its surroundings with respect to a particular factor is likely to attract attention. Previous research has involved the visual search task of a target, eye movement studies, and other psychophysical and psychological tests. There are a number of factors that have been found to influence the salience of stimuli, such as orientation, luminance, colour, size and contrast (Nothdurft, 1993; Findlay, 1980; Stark et al, 1993; Zenger-Landolt and Fahle, 2001).

For example, a target that moves in a direction different from that of its neighbours is salient, as is a line that is brighter than its surrounding lines or is different in colour (see Fig 1).

In the context of the urban night

Lighting Journal May 20144

scene, the saliency of an object would depend on its luminance and colour contrast. Colour provides a unique source of information for separating objects from their background. This is called a figureground segmentation or discrimination – the presence of an object can sometimes go completely unnoticed were it not for the colour differences.

This can be easily observed in the natural environment, where animals and plants use colour to call attention to themselves or, by contrast, to camouflage themselves by being assimilated into the environment.

The results of many previous works have emphasised the importance of colour as a visual attractor (D`Zmura, 1991, Nordthurst 1993, Itti et al, 1998). For instance, a number of studies has investigated the relationship between the colour difference of the target and the distracting stimuli, and the time of visual search of the target. These

studies demonstrated that large colour differences can dramatically influence the saliency of an object and contribute to visual search and better identification performance. It has also been shown that, where there is a small colour difference between the stimulus and distracter, the time to find the target increases significantly (Carter, 1982).

Some other studies have demonstrated that colour also helps to distinguish and localise the objects when there is low luminance contrast between the background and the object (Rivest et al, 1996; Gur et al, 1992). Obviously, colour provides a clear landmark that allows the objects to attract our attention even within highly cluttered environments.

Previous studies have demonstrated that all three attributes of colour – hue, brightness and saturation – can influence its perception in space. For instance, increasing the relative contrast of

Fig 1: Salient examples – the red bar in the left picture pops out due to its direction. In the right-hand picture, the red bar pops out because of its colour

blue, green or yellow (the colours were picked from the CIELab colour space). To reveal the effect of the hue on the saliency, lightness and saturation levels were held equal for all coloured targets. It was decided to change the general background of the image to achromatic because of the colour contrast, which could alter the appearance of the coloured target object in case the background was kept in its original state.

Fig 2: Perceived brightness ratio

an object by enhancing the colour saturation or luminance in respect to its background changes the object’s apparent position, making it appear closer and, consequently, more salient (Taylor and Sumner, 1945; Johns and Sumner, 1948; Mount et al, 1956; Turatto, 2000).

In terms of particular hues, the colour red seems to have been found to be more salient in the majority of studies. However, some studies demonstrate different findings as the effectiveness of the individual dimension of the colour depends on the experimental context, and there may be a combined effect of colour attributes on the saliency of coloured objects.

It is best demonstrated in the Helmholtz-Kohlrausch (HK) effect where the saturation of a spectral hue is perceived as part of the colour’s luminance, and different colours are associated with different brightnesses.

In CIE terminology it is a ‘change in brightness of perceived colour produced by increasing the purity of a colour stimulus while keeping its luminance constant within the range of photopic vision’. This applies both to lights and object colours.

The HK effect is stronger in some hues than in others (Ikeda and Ashizawa). Specifically, stimuli that are more saturated (appear purer in colour) are perceived as being brighter than stimuli that are less saturated at the same luminance: the effect is nearly absent in yellow-green to deep-yellow hues, rather high in orange, green and blue hues, and very distinct in extreme orange-red, blue-violet hues.

This perceived brightness might better be called chromatic luminance, since ‘white’ or achromatic luminance is the standard of comparison.

The HK effect varies significantly

across observers – it can be quite pronounced in some views and nearly non-existent in others. Fig 2 shows an approximate ratio of what the ‘white’ light would have to be relative to the coloured light to appear to be the same brightness.

Aims of study My study attempted to investigate the saliency of different hues of coloured illumination in a night-time urban environment and the extent of the Helmholtz-Kohlrausch effect in this particular context. Two hypotheses were further summarised and experimentally tested: • Objects of different hues, but of equal saturation and lightness level, are expected to have various saliency levels • Saliency of objects of different hues is expected to be influenced significantly by its inherent chromatic luminance Methodology The experiment was conducted in a dark room with lighting kept at low photopic levels, similar to those in night-time urban environments. Using purpose-built software, 19 subjects were shown pairs of images, one with an achromatic and one with a coloured target. The subjects were asked to identify which of the two presented stimuli appeared more salient in order to evaluate the saliency threshold for each colour.

Both images represented an identical urban night-time scene, where the target object was a statue (Fig 3).

Depending on the subject’s response, the luminance of the achromatic target changed for each set of pairs, while the coloured object always had a constant luminance.

The coloured target was either red,

Results The average results of the perceived luminance for each hue across all subjects demonstrated that red was perceived as the most salient colour with a well-defined leading position, followed by green, yellow and blue.

Red was hit as the most salient colour 15 times out of 19, with a big gap between green and blue, which were hit only four times and twice respectively.

Although red was found to be the most salient colour in this study, confirming previous findings, the fact that blue was found to be the weakest colour appears to contradict studies of the Helmholtz-Kohlrausch effect and did not support the hypothesis that saliency can be significantly influenced by the chromatic luminance of hues.

A number of factors could have influenced the results, starting from the general methodology and the time-dependent nature of this study, through to it involving an image of an urban environment with various luminance levels, rather than the neutral image used in the studies of the HK effect.

In general the results demonstrated that all four hues were perceived as considerably brighter compared to their actual luminance values. This is consistent with the studies related to heterochromatic lightness matching where, in general, the chromatic colour is perceived as brighter than an achromatic colour of the same luminance.

As for the variance of individual saliency threshold levels, the results are consistent with studies of the HK effect, where it was shown that its magnitude differs considerably across subjects. The difference in saliency levels between the four hues found in the present study is also consistent with a complex phenomenon of the HK effect, which demonstrates that the contribution of the chromatic channels is significantly different for different

Fig 3: Images represented an identical urban night-time scene, where the target object was a statue. Subjects were asked to identify which of the two presented stimuli appeared more salient

hues, even though the test chromatic colours have the same luminance and chroma values.

Furthermore, analysis of the saliency levels of all hues, where they were compared with each other, showed a generally high correlation.

These results suggest that the threshold levels of individual hues are a result of the individual sensitivity of each subject. If a subject has a higher perceived saliency threshold for some of the four hues, there is a high chance that all other colours will also have a higher threshold level.

The higher saliency levels of red compared to other colours could have several possible explanations. On a larger scale, as noted by Humphrey, the significance of the colour red could be related to the fact that it is the most common colour signal in nature, which can be further justified by the physical properties of red making it the ‘fastest’ colour with the lowest refraction index.

Another possible explanation could arise from the chromostereopsis effect, which suggests that red is perceived as the ‘nearest’ colour.

However, this notion is under question, as reversal of chromostereopsis would be expected in the illuminance levels under which the present experiment was conducted. Most experiments of chromostereopsis have been conducted using artificial pupils,

Lighting Journal May 2014

in quite uncontrollable conditions (Simonet, 1990), and there are some more recent studies that didn’t show reversal in lower photopic illumination levels. Additionally, the fact that most of the immediate area around the target was black, could contribute to the advancing effect of the colour red.

The above is just an attempt to explain possible effects that could influence the outcome of the present experiment. However, the aim of this study was to reveal the different saliency levels of various hues, and the experimental procedure involved the assessment of this aspect rather than brightness or nearness perception. As saliency is a complex phenomenon dependent on many aspects, some other underlying mechanisms could lead to the final findings of the experiment.

Furthermore, the results could also be influenced by the experimental approach of the study.

Significance Exterior illumination has begun to play a significant role in the creation of an attractive and active nightscape, as night-time activities in cities have gradually increased over the years.

Nowadays, it is common practice for the client or architect to require an illuminated night view of a building that will provide a memorable

experience for the customer, viewer or spectator. This is often used as part of the marketing strategy to promote building facilities.

On a larger scale, they can help promote buildings, monuments, or other architectural and cultural objects as city icons. A result of this tendency is the wide adoption of building illumination, with schemes becoming more impressive and vibrant, and with coloured lighting playing an increasingly major role.

Until relatively recently, colour hasn’t been a big part of the architectural lighting armoury.

However, due to rapid progress in lighting technology it is quickly becoming mainstream. Walking through a contemporary city today can be an unexpectedly colourful experience. The most significant change has resulted from LED development, providing an immense versatility in application, energy efficiency and variety of colour.

In highly cluttered environments with all possible variations of lighting, it has become more and more difficult for any particular lighting scheme to stand out. Luminance contrast is traditionally used to improve the conspicuity of objects at night and it is generally achieved by increasing the luminance levels of an object.

However, the brightness perception of coloured light is different from that of white light and therefore applying the same approach to coloured lighting cannot provide any certainty of how it will be perceived, simply because our visual perception reacts differently to white light compared to coloured light.

The prime purpose of the study was to investigate whether another attribute of coloured light, hue, can influence the saliency of objects in the night-time urban environment. This research demonstrated the importance of considering hue when designing a lighting scheme, where saliency of an object is a key consideration, and that it can successfully be used as a saliency medium, along with luminance contrast and saturation.

Glasgow has big plans to upgrade its lighting stock, not only to save energy but to push the potential of the latest technology in new ways. Francis Pearce talks to George Gillespie, assistant director of Land and Environmental Services, about the city’s vision for the future

George Gillespie

A

lmost 12 years after Glasgow’s far-sighted lighting strategy was officially launched, it recently helped the city win a £24m trailblazing competition, enabling it to trial technology that gives street lighting – and lighting engineers – a central role in the city’s plans for sustainability.

Glasgow beat 29 other UK cities to win the funding in the Technology Strategy Board’s Future Cities Demonstrator competition. Its aim is to show how technology can make life in the city ‘smarter’, safer and more sustainable, and to inform policy and future investment across the UK. Glasgow will use the money for seven ‘demonstrator’ projects. They include developing what it calls ‘a one-stop shop City Dashboard’ to monitor city systems from traffic lights and street lighting faults to CCTV, air quality, journey planning

‘We’re no longer just “boring lighting engineers” – we are demonstrating the potential of street lighting, its location and its role in the infrastructure’ Buchanan Street, an early use of coloured light (1999) in a scheme by Speirs and Major Associates: ‘The lighting strategy incorporated all aspects of lighting. The use of coloured lighting kicked it off’

and even hospital waiting; an Integrated Operations Centre, and Sustainable Glasgow, whose broad remit includes energy conservation and white street lighting.

Glasgow’s is also the first local authority in Britain to sign up for a new Green Loan for LED street lighting from the UK Green Investment Bank (GIB).

The £8.6m loan covers the set-up, capital investment and installation costs of lighting upgrades and will be paid for through energy savings.

In November, the council announced the first phase of a programme to refurbish 72,000 ageing sodium lamps with LEDs by the end of 2015. The city’s existing lighting stock costs it around £8.5m a year to run.

Installing the first 10,000 LED street lamps will cost the full £8.6m but the move to LEDs should eventually cut Glasgow’s street lighting energy bill

by 65 per cent and reduce annual carbon emissions by an estimated 45,000 tonnes.

‘All of it has to do with inward investment, and the fact that we made one of five demonstrator projects street lighting was very important,’ says George Gillespie, assistant director of Land and Environmental Services, which oversees the Future Cities projects and is one of three main departments responsible for lighting strategy delivery.

Gillespie says both recent decisions benefited from Glasgow’s track record in planning and piloting lighting projects. ‘When the Future Cities competition was announced, we looked at what would be right for demonstrator projects and street lighting was always an area of interest: the different aspects of street lighting and its benefits including public safety

aspects, public perception of safety, and energy efficiency,’ says Gillespie.

‘And if you go back to the lighting strategy, it ticked all those boxes.

‘For us, the present benefit has been to pilot various lighting technologies and to assess them not only from a council officer perspective or a lighting engineering perspective, but also from the householder’s point of view and that of business,’ he continues. ‘But what happens after the Future Cities programme comes to an end? What is the legacy? When we have demonstrated what a smart city can do what I’m looking for is the business case that will allow me

to approach the Administration and show the additional benefits and advantages of street lighting.’

Glasgow’s City of Light lighting strategy implemented or contributed to 100 lighting projects of varying scale.

Its aim was to bring visual coherence to the city’s lighting, including individual buildings and landmarks, statutory street lighting, amenity and festive lighting; to improve the quality of the environment after dark and to complement regeneration initiatives.

The 100th project was at Glasgow Cathedral in 2009 and marked a movement away from lighting major city landmarks to a more locally based approach to regeneration.

In the meantime, Glasgow also became active in Lighting Urban Communities International (LUCI) leading to two editions of the Glasgow Radiance Festival of Light in

November 2007 and 2009, both with safety and the perception of safety among its core aims. One effect was to make the city more colourful at night. In 1999 Speirs and Major Associates had lit the busy Buchanan Street blue; later other city icons such as the ‘Squinty Bridge’ would take on their own colourful character and the Glasgow Housing Association would brighten Glasgow’s tallest housing blocks with RGB LED lighting that forecast the weather.

‘The lighting strategy incorporated all aspects of lighting,’ says Gillespie.

‘The use of coloured lighting kicked it off whereby we had decorative lighting, including LEDs, to put coloured lighting on to public buildings, and white lighting on the main arterial routes. More than 160km have been converted. Main roads were converted to metal halide and on the residential streets, we opted for fluorescents.

Urban lighting If you ever fly into Glasgow you can pick out all the main roads and the city centre from the air,’ he says.

‘But that was a decade ago. LED technology is now to the fore and two years ago we engaged in pilot projects that are now under the umbrella of our Sustainable Glasgow programme, which explores ways for new technology to make the infrastructure more efficient.’

That includes looking at new ways to apply lighting management technology, he says. ‘Intuitive’ lighting is being installed on parts of the National Cycle Network, including a stretch that runs along the Clyde waterfront, for example, where lighting levels increase ahead of cyclists, rising from 40 per cent to full brightness.

Another, bigger project takes in the high footfall area in Gordon Street outside Glasgow Central Station, an area with average city centre

footfall and a pedestrianised area with cafes. Here the LED lighting will be combined with CCTV and video analytics systems, and linked to the new communications centre for road traffic control, public safety and policing. Lighting levels will be used to deter antisocial behaviour or for crowd control rather than just for special events or to save energy.

‘Since the Technology Strategy Board grant to us we have been approached by a number of manufacturers with technology that is not just lighting but can be used for a number of functions by authorities such as the police,’ says Gillespie. In February, Glasgow also awarded BT a contract to install up to 80 wireless points on its street lighting units, providing free Wi-Fi in the city centre and East End ahead of this year’s Commonwealth Games.

‘We decided to remove poles and

17

replace them with wall-mounted units 20 years ago to reduce street clutter.

Now we will be using the wall-mounted units to provide this as part of our Digital City programme.’

Traditionally what was done in the past was purely about road lighting. ‘That was its sole purpose,’ concludes Gillespie, ‘but street lighting is becoming more multifunctional.

That gives us a lever. It gives us other opportunities. It allows us to replace lighting stock and it also gives us an added advantage in terms of attracting more investment.

‘We are part of the management of the communications centre and we are using street lighting for public safety purposes, which has never been done before,’ he says. ‘And we’re no longer just “boring lighting engineers” – we are demonstrating the potential of street lighting, its location and its role in the infrastructure.’

‘Street lighting is becoming more multifunctional. That gives us a lever. It gives us other opportunities. It allows us to replace lighting stock and gives us an added advantage in terms of attracting more investment’

Light pollution

and Are stellar fractal patterns important to health? Nancy Clanton gives a US perspective on light pollution and the lighting designer’s role in its prevention

B

eing able to see the stars at night may seem romantic. But is it also important to our health?

It’s only in the past 100 or so years that human beings have been lighting up the night with electric light sources.

Our ancestors evolved with sunlight during the day, and star/moonlight at night. We are now living in a world filled with electric illumination with little resemblance to the star-filled nights of yesteryear.

What are we missing by not viewing the stars every night before we go to sleep? I am fortunate to live in a community where the Milky Way is clearly visible. Looking at the infinite depth of the galaxies is calming and relaxing. My question is, how important are these fractal patterns of stars in providing calm before sleep?

As our world population becomes more urban, these opportunities are disappearing through light pollution, especially for future generations.

Unlike air pollution, light pollution can be stopped instantly, as demonstrated when a region loses electrical power.

This happened during Hurricane

Lighting Journal May 2014

Sandy, when the stars were visible for a few nights over New York City.

Light pollution or sky glow is, as we know, light scattering in the atmosphere, obscuring the view of the stars. It is caused by short wavelength or blue light scattering (Rayleigh) in the atmosphere. During the day, the scattering creates the blue sky. At night, this same blue light creates sky glow. In the UK, of course, it is sodium orange that is reflected/refracted.

The importance of reducing light pollution is an ongoing debate in the US. Reflecting opinion elsewhere, many biologists believe that light at night (LAN) has ecological consequences such as disrupting animal breeding habits and nocturnal behaviours.

The impact on turtle nesting areas is well known, and LAN may have more adverse effects on other animals and people. The American Medical Association has listed LAN as disruptive to circadian cycles.

In addition to these well-known issues, are views of stars also essential? It is well known that views of nature during the day are important, but what about at night?

All outdoor light, whether direct or reflected, causes sky glow. Direct light, especially at low angles near 90-degree horizontal, is the most damaging, since it is going through the thickest part of the atmosphere. As mentioned earlier, short wavelength light is absorbed the most in the atmosphere, creating the highest amount of light pollution.

There are currently very few standards or recommendations to reduce light pollution. While in the UK there is both ILP and CIE guidance,

in the US the International DarkSky Association and Illuminating Engineering Society jointly published a Model Lighting Ordinance (IDA/IES MLO) in order to help communities regulate outdoor lighting.

It is primarily a prescriptive-based model, assigning lighting zones to community areas and then regulating the amount of lighting (luminaire lumens) and limiting luminaire classifications for backlight, uplight and glare (BUG). In addition, reducing light levels during curfew hours is also encouraged. The MLO is an excellent first step in curbing light pollution, but generally more should be done in evaluating our lighting level recommendations.

Energy efficacy has traditionally been related to the CCT or spectral distribution of a light source. Typically, the higher the CCT, the more lumens per watt (although sox lighting has a high efficacy of around 160lm/W).

Also, high scotopic to photopic (S/P) ratios are produced by higher CCT light sources. High S/P ratios allow designers to apply mesopic multipliers, resulting in higher lumen ratings.

All of this comes at an environmental cost. More blue light, more sky glow. The balance between saving energy and minimising sky glow is a critical design decision.

A challenge to manufacturers is to increase efficacies of light sources with lower CCT and/or less short wavelength light.

Current design standards and recommendations use illuminance, luminance and uniformity as the basis of design. These are simple to calculate and measure. It could be

Light pollution argued that these criteria have little to do with visibility, since they do not take into account visual adaptation, glare or spectral contrast. Veiling luminance and limiting glare (G) ratings in the MLO are an attempt at regulating glare. Discomfort and disability glare are not completely taken into account.

So what can lighting designers do to reduce light pollution?

• Do not overlight: Safer environments do not necessarily equate to high light levels. Research has shown that object detection distance (visibility) has more to do with colour contrast and nonuniformity than highly uniform overlit streets. Adaptation from one area at night to another is also an issue with overlighting.

Imagine driving out of a petrol station that has high light levels on to a street with no street lighting. It may take minutes for elderly eyes to adapt.

• Direct light downwards: This should apply to all ambient or general lighting schemes. In addition, minimising glare will help people adapt within their visual field. If uplight is required, have it minimal, only for a soft glow or focused accent.

• Use warmer colour temperature light sources: This reduces short wavelength light (below 480nm) as blue light scatters the most in the atmosphere.

• Specify luminaires that have little glare and uplight: In the US, the IES TM-15-11 Luminaire Classification System for Outdoor Lighting has BUG ratings. These ratings provide guidance for the designer in selecting appropriate ratings for different ambient lighting conditions. Specifying luminaires with U0 will have no uplight.

G2 and below will typically be low glare.

• Dim or turn off lighting during low or no activity levels: Dimming lighting is now very viable, especially with wireless,

•

•

Dali or DMX control systems.

Individual I/P addresses can provide the maximum flexibility in changing schedules, programme or assignment changes and life/ maintenance of each luminaire.

Light only when necessary: Deciding when to light or not light is a complicated design decision.

The first step is to decide who or what has the highest priority in an area. For example, in a wildlife preserve, animals are the most important such that light should not be used or used sparingly. If the answer is humans, then lighting design may depend on expectations.

A low-activity footpath, may need lighting only at decisionmaking points. Urban footpaths may require continuous lighting.

Both lighting levels and controls can also contribute to these design decisions.

Use lighting zones: Lighting zones address community expectations, and can help in determining adaptation levels.

Educate the public: More light is not necessarily safer. This may go completely against general public opinion, but it is true.

Develop design criteria: Contrast-based criteria that take into account adaptation may show that less non-uniform light may give the greatest contrast, equalling better visibility.

Visibility-based design criteria need to be developed, using spectral contrast and luminance of a scene.

These revised criteria have the potential to prevent overlighting, reduce glare and increase colour contrast, all resulting in reduced light pollution.

Ideally, spectral distribution can also be tuned to correspond to circadian cycles. All lighting should dim or turn off in response to activity levels, lumen maintenance and ground cover (snow).

In addition, performance-based sky glow metrics and calculation tools also need to be developed to

19

help designers predict light pollution potential. Sky glow meters are currently available to document current and future conditions.

This is a huge change from our easy-to-calculate, easy-to-measure criteria, but it is well worth it.

My good friend Paul Bogard has written a book called The End of Night:

‘Visibility-based design criteria need to be developed, using spectral contrast and luminance of a scene.

These revised criteria have the potential to prevent overlighting, reduce glare and increase colour contrast’ Searching for Natural Darkness in an Age of Artificial Light. In his book, he walks us through his personal experiences with increasing sky glow. Below, Paul describes a dark sky experience that few people will appreciate in their lifetimes: ‘These are maybe the most exciting stars, those just above where sky meets land and ocean, because we so seldom see them, blocked as they usually are by atmosphere…and, as I grow more and more accustomed to the dark, I realise that what I thought were still clouds straight overhead aren’t clearing and aren’t going to clear, because these are clouds of stars, the Milky Way come to join me.’ www.hachettebookgroup.com/ titles/paul-bogard/the-end-ofnight/9780316182904/ Nancy Clanton is founder and president of Colorado-based Clanton and Associates, a lighting design firm specialising in sustainable design.

International Year of Light

Light years away?

Specially designated to lighting by the UN, 2015 should present a golden opportunity for both the industry and profession.

Except that so far it hasn’t involved a single lighting body.

Jill Entwistle reports

T

he fact that the UN, through Unesco, has designated 2015 as the International Year of Light ought to be a pretty significant development for the lighting industry and a cause for celebration. But perhaps surprisingly there still seem to be a substantial number of people who haven’t heard of it, and among those who have, there is considerable confusion as to what exactly it entails. And not a single lighting body is involved.

The UN General Assembly proclaimed 2015 as the International Year of Light and Light-based Technologies in December 2013. It was the initiative of a consortium of scientific bodies together with Unesco, and will bring together a variety of stakeholders including scientific societies and unions, educational institutions, technology platforms, nonprofit organisations and private sector partners.

The resolution to endorse it was adopted by the Unesco Executive Board in October 2012 after Ghana, Mexico, the Russian Federation and New Zealand put it before the board. A further 28 assorted countries – from Angola to Zimbabwe with the US, UAE, Italy, Spain and Saudi among those in between – signed up, with a few others declaring support. Not the UK, you will note.

‘An International Year of Light is a tremendous opportunity to ensure that international policymakers and stakeholders are made aware of the problem-solving potential of light technology,’ said John Dudley, vice president of the European Physical Society and chairman of the IYL 2015 steering committee. ‘We now have a unique opportunity to raise global awareness of this.’

At this juncture the bias seems to be with the academic and scientific establishment, especially physicists, and with technological developments such as nanophotonics and quantum optics, and the applications of light in spheres such as medicine and communications. The current endorsers say it all: the International Union of Pure and Applied Physics (IUPAP), the IUPAB (Biophysics), IUHPS (History and Philosophy of Science); IAU (Astronomy); ISPRS (Photogrammetry and Remote Sensing), and URSI (Radio Science), among others.

The IYL will run parallel with the Unesco International Basic Sciences Programme (IBSP) and, according to the

Lighting Journal May 2014

prospectus, ‘will promote the central role of light in science and culture, the importance of light-based technologies for the equitable development of global society’.

However, the prospectus goes on to add, ‘the project is not only about science – light also touches on culture, history and education. Issues of sustainability and development are also of central importance’.

The appreciation of natural light phenomena are viewed as a route to inspiring interest in the scientific aspects, as well as highlighting environmental issues such as energy usage and light pollution.

‘This theme will raise awareness of the beauty and accessibility of science through activities that will encourage and support observation of light and colour in the natural world,’ says the prospectus. ‘And, of course, this theme provides a natural place to consider how observing light in nature often means turning off the lights from modern society. While modern lighting provides important and crucial opportunities and advantages in improving quality of life, raising awareness of the issue of light pollution will also be an important feature of this theme.’

Prospectuses at this stage are invariably a bit woolly and short on specifics, but as has been pointed out in a series of outraged blogs and online forums, there is no mention of lighting design or even specification in any form. Given that lighting professionals of all types are significantly responsible for the quality of the lit environment, as well as energy use and the avoidance of light pollution, their involvement would, to say the least, seem both logical and necessary.

It appears at this stage that it is lighting bodies such as the ILP which will have to bang the drum and raise awareness of the role that the lighting profession and industry plays in all this. Otherwise the impression the world will gain at the end of 2015 is that light is primarily about enabling whizzy technological development.

The official UN International Year of Light had not gone live at time of going to press but the prospectus is available from the European Physical Society (www.eps. org/?page=event_iyol ), home of the secretariat, among other sources

Potential activities

Unesco mission statement

A year of pioneers A 12-month calendar will associate each month with a particular scientist, and his or her contribution to the science of light. Classroom kits for schools will provide biographical and scientific information. Calendars will be made for international and regional dissemination.

The International Year of Light is a global initiative which will highlight to the citizens of the world the importance of light and optical technologies in their lives, for their futures and for the development of society.

Light in the universe Particular celebrations will focus on advances in the years 1815, 1865, 1915 and 1965 that established light’s place at the centre of modern science: 200 years of the wave theory of light, 150 years of the theory of electrodynamics, 100 years of general relativity and 50 years since the discovery of the Cosmic Microwave Background will provide key scientific focal points.

A LightDay for Earth To illustrate the unifying nature of light around the world, one particular day of the year will focus internationally on the role of light in nature, light conservation, and means of reducing light pollution. We will coordinate with existing annual events of this nature.

The light touch: hands-on optics Building on existing partner activities, we will develop educational kits illustrating the principles of optics appropriate to the needs of institutions in both the developed and developing world. Focusing on instruments such as eyeglasses and microscopes will ensure societal relevance.

Bright futures This activity will be a year-long programme of educational activities linking specifically to careers in science.

Addressing gender issues and promoting science careers for women in developing countries will be a priority.

Light for change The availability of inexpensive and energy-efficient lighting can revolutionise the quality of life in the developing world.

Partners will support and develop initiatives promoting lighting of this sort worldwide.

The Daily Scientist Volunteer scientists – from PhD students to professors – will communicate their day-to-day experiences to the public at large using social media such as blogs, Facebook, YouTube.

This will place a very human face on the scientific and engineering community.

Capturing light Nature provides many beautiful and inspiring examples of optical effects such as mirages, rainbows and so on.

A year-long international competition among schools will solicit photographs of natural optical phenomena that will be posted on a centralised website. Winners will be announced monthly.

– International Year of Light prospectus

The International Year of Light will consist of coordinated activities on national, regional and international levels.

Activities will be planned so that people of all ages and all backgrounds from all countries appreciate the central role of light in science and culture, and as a cross-cutting scientific discipline that can advance sustainable development.

Goals • Improve the public understanding of how light and light-based technologies touch the daily lives of everybody, and are central to the future development of the global society.

• Build worldwide educational capacity through activities targeted on science for young people, addressing issues of gender balance, and focusing on developing countries and emerging economies.

• Enhance international cooperation by acting as a central information resource for activities coordinated by learned societies, educational establishments and industry.

• Focus on particular discoveries in the 19th and 20th centuries that have shown the fundamental centrality of light in science.

• Highlight the importance of research both into the fundamental science of light and its applications, and promote careers in science in these fields.

• Promote the importance of lighting technology in sustainable development, and for improving quality of life in the developing world.

• Highlight and explain the intimate link between light and art and culture, enhancing the role of optical technology to preserve cultural heritage.

• Maintain these goals and achievements in the future beyond the International Year of Light.

International Year of Light

‘As light becomes the key cross-cutting discipline of science and engineering in the 21st century, it is essential that the brightest young minds continue to be attracted into careers in this field’ – International Year of Light prospectus

The verdict of the lighting profession Mark Major MILP Principal, Speirs and Major Anything that raises the profile and value of ‘light’ worldwide has to be a good thing – though only as long as the message is the right one.

As I understand it the UN has initiated this to underline ‘the importance of raising global awareness of how light-based technologies promote sustainable development and provide solutions to global challenges in energy, education, agriculture and health’.

The aim appears to be to promote light in the widest form of its use – for communications, agriculture, medicine and so on. I am not sure that Unesco necessarily had environmental lighting in mind.

As a result the proclamation seems to be largely about the ‘science of light’ rather than the ‘art of light’. Much as the science is absolutely critical, the reference to raising the awareness of ‘technologies’ would worry me in the context of what we do. It draws us back to the idea that lighting solutions are all about products, tools and systems rather than the proper analysis of underlying social and economic benefits that light can bring – that and asking basic questions about how much light we actually need to use, where and why.

The UK lighting bodies should certainly get in there and stake a claim to be the voice of the professional lighting design community. I do not believe that the ILP was not one of the ‘learned bodies’ that put this idea forward (neither were the IALD, IES or any other organisation associated with environmental lighting).

Maybe we should change the current directive to: ‘the importance of raising global awareness of how light-based design promotes sustainable development and provides solutions to global challenges in energy, education and health.’

Lighting Journal May 2014

Mark Ridler Director BDP Lighting, VP architectural of the ILP and Lighting Designer of the Year 2014 The participating bodies apart from Unesco are mainly educational and scientific organisations, primarily concerned with photonics, optics and the physics of light. The IYL seeks to bring together technology platforms, education and scientific societies through a commemoration of the scientific achievements in light and the practical impacts going back 1000 years. Currently lighting for the built environment appears not to be on the table.

This is an opportunity that the profession of lighting design should not miss: • To let political bodies know we exist. To raise their agendas above the base level of ban the bulb and street lighting switch off • To articulate the benefits that design can bring to quality of environment, human health, welfare, effectiveness and reduced impact on the environment (be it energy, light pollution, ecology, or recycling) • To advocate the better consideration of daylight in building design • To educate about the potential benefits of design beyond the purely aesthetic • To promote high quality and ethically responsible manufacture • To identify lighting design as a profession to the education sector • To initiate research in the topics we all need to support evidence-based design National/regional committees are being set up now as contact points and our professional bodies, the ILP, SLL, IALD, should all be trying to get a seat at the table. There will undoubtedly be a conference and there should be at least one speaker from our community there. As consultants we should engage with our professional bodies to ensure that they reach out and support them when they do.

Peter Raynham Senior lecturer at the Bartlett, UCL It will raise awarness of the importance of light and lighting in the general public. It’s important that UK lighting bodies get together with all of the other bodies associated with this initiative and promote it as much as possible.It is also potentially an opportunity for political lobbying. However, while it is an opportunity for some people to exploit, I hope they don’t. I wouldn’t want this year to turn into nothing more that a cynical marketing

International Year of Light exercise with people simply trying to make money out of it.

For me, the International Year of Light is a great opportunity for everyone in the lighting world to get together with partners that we have not traditionally worked with (such as the Institute of Physics, which is leading the project in the UK) to promote awareness of the importance of light in all its forms. I am sure that we are going to see a great number of events badged with ‘Year of Light’ and it is to be hoped that this extra push in promoting light has enough presence to get the message that light and lighting are important out to the public at large. In any event we will see many major lighting events in the UK, including the weeklong CIE Quadrennial Conference which will be held in Manchester at the end of June next year.

Barbara Horton, senior principal HLB Lighting Design and IALD president Light and lighting in the built environment are where art and science meet for lighting designers and most people. The International Year of Light 2015 offers a terrific opportunity to help draw public attention especially to the impacts of light on human comfort, productivity and wellbeing, and the ways we can combine the best practices in design with the most current technology to improve quality of life and reduce negative environmental impact. In short, IYL 2015 will provide a framework for lighting organisations around the world to build public and policy-maker understanding of the role that light and lighting play in daily life.

Pete Lummis Project engineer for Huntingdonshire District Council and immediate past president of the ILP This should raise the public profile of lighting in all its disciplines, and will provide a backdrop for educating the public about the central role of lighting in their lives.

UK lighting bodies should be helping to raise the profile of this by holding individual and joint events with other organisations to promote the science, technology, nature and culture around light and lighting.

The ILP should take advantage of the worldwide interest and push our local agendas. It is interesting to note that the UK was not one of the co-signatories of the Unesco Executive Board session in October 2012 in Paris, but I hope this country will nevertheless be supportive.

I also think it would be good if: • • •

Graham Festenstein MILP Graham Festenstein Lighting Design At first I was very excited by the idea of an International Year of Light – at last, I thought, an initiative that will raise awareness of light and lighting on a global level. However, as I read through the prospectus I became more and more disappointed.

Yet again we have a document that plays lip service to, and almost entirely ignores the primary interface between the science of light, our society and the people who live in it.

But why? Is this ignorance, or an example of the latent snobbery many academics have about the applied disciplines of design and engineering outside of the lab?

Even where it discusses light and culture, it does so in simplistic terms, and sidesteps the creative application of light, concentrating, for example, on the control of light pollution as the primary goal for architectural lighting.

This is not to say I think the principles identified are not positive and important, or that the promotion of science is not a very important topic that should be raised and discussed publicly. However, I believe they are destined to fail to deliver their goals if they do not expand their horizons, to understand real world light-related issues – creativity, practicality, sustainability and wellbeing to name a few, that affect our societies and the citizens within them.

So what should be done? Our professional bodies should rise to the challenge to promote our industry. A collaboration on a global scale with organisations such as the ILP and IALD joining forces, to lobby the organisers to expand their brief, bring us on board at a high level where we could make a serious and worthwhile contribution.

There is also an opportunity to piggyback on this programme, to lobby politicians and raise awareness of lighting design to the wider community and the general public. Lighting design is not peripheral to the discussion of light, it is an integral part of it.

We must not separate the art from science. What we do is not just a simple application of scientific principles, it should be, and is, an integrative relationship, and without acknowledging as much is surely a wasted opportunity.

If the organisers don’t like it maybe they should rename their project the Year of the Physics of Light and fail to speak meaningfully to anyone outside of their own fields.

In order to properly predict the performance of an LED lighting system and to accurately compare results to competing LED and conventional lighting systems, lighting engineers and designers must be particularly careful to use appropriate LED Maintenance Factors.

Calculations to predict performance lighting installation are fundamental to the practice of lighting design and lighting engineering. These calculations allow lighting engineers and designers to predict lighting performance and whether the design meets and complies with the correct specification and performance recommendations.

Exhibition review

Highly connected In the first of a two-part review Jill Entwistle looks at some of the stand-out sources and interior luminaires at this year’s Light and Building exhibition in Frankfurt If there was one perceptible trend at this year’s Light and Building it was the emphasis on smart lighting, with a number of companies showing wireless systems linked to smart devices or smart lamps (Samsung).

They ranged from residential and small leisure applications (Megaman) to Philips ‘groundbreaking’ system that uses Power-over-Ethernet (PoE) to connect office lighting fixtures to a building’s IT network. Lighting has moved to a different, highly responsive level. Connectivity was the buzzword.

But when it came to luminaire development things weren’t quite so exciting. As in agriculture, luminaire development needs a fallow period.

In lighting it happens roughly every four years, coinciding with every other Frankfurt show. While specifiers visit in eternal hope of novelty and inspiration, the pace of progress has

been such that it is understandable that manufacturers need a period to consolidate, refine and fine tune. It may be less exciting but the rush for the biggest and brightest has to be tempered by attention to areas such as optics, controls and components if a quality, useful product is to emerge at the end of all the hype.

There was an awful lot of similarity across the stands: the flat suspended oblong fitting, often transparent in the off state; the recessed ribbons of light that are becoming obligatory; the suspended modular system, now sleekly discreet thanks to the LED. So, to coin the cliche, in this respect at least this year’s L+B was about evolution rather than revolution.

There was still an element of arms race when it came to sources, however: Osram, determined to pip Philips to the post, boasted the highest

SOURCES

Cree CXA High-Density LED Arrays While its 300lm-plus LED is still in the lab, Cree’s three new high-density arrays are among a range of more powerful formats it is launching. They double the light output of existing standarddensity CXA arrays without an increase in size. The most powerful is the CXA2590 which emits more than 15,500lm from a 19mm source, putting it in the same bracket as a 150W CMH lamp. The CA 1850 delivers more than 9000lm from a 12mm source, equivalent to a 70W CMH. Designed for smaller track fittings, the 6mm CXA1310 (above right) provides more than 2000lm. Another innovation, the LMH2 module (top right), offers ‘sunset’ dimming technology, moving smoothly from 2700K to 1800K to achieve the warm light of a sunset. www.cree.com

Lighting Journal May 2014

output retrofit LED tube at 215lm (Philips has long been flagging up its 200lm tube); Cree has busted another barrier with a 303lm/W LED (lab conditions), and LG Chem claimed the world’s largest OLED at 320mm x 320mm. Apart from LG Chem’s effort and Sumitomo’s dual-coloured panels (see Lighting Journal April), OLEDs seemed to take more of a back seat this year. There were little waves of the flag around the show, just to keep things on the simmer. Toshiba had a prototype transparent version, while Philips claimed the brightest commercially available OLED panel with an output of 300lm.

When you’re trying to grab attention among hundreds of exhibitors you have to have a few showstoppers. Quite how some of those figures will translate to everyday realities remains to be seen.

Osram 215lm/W LED tube Billed as the world’s most efficient lamp, Osram’s 1.2m LED tube achieves 215lm/W (system efficiency 205lm/W), an output matching fluorescent but at half the power. The peak efficiency is achieved both with warm and cool white light. The 19W tube features a combination of high-efficiency red LED chips and greenwhitish Osram LEDs containing a self-developed phosphor ‘that is approaching production maturity’. So not quite ready for market. Materials with maximum reflection factors are also used, as well as an innovative, integrated optic that minimises light absorption. The lamp is operated with a specifically developed control unit with an efficiency of 95 per cent. The prototype tube emits 390lm of warm white light (3000K) and achieves CRI 90. It’s scheduled to be available commercially in 2015. www.osram.co.uk

Exhibition review Megaman Incanda-LED Philips Lighting Sparkling 40W lamp Sylvania GLS Omni-Directional The quest to approximate incandescent lamps continues apace. On the evidence of a rash of lamps launched at L+B the current focus has moved from colour temperature to light distribution and recreating the sparkle of the filament, a particular issue with fittings such as chandeliers where the flatness of LED sources rather kills the effect. The Megaman Incanda-LED series (top) is designed to deliver the sparkling light effect and covers the range of different lamp types with candle and classic shapes in E14 and E27 bases. Designed to replace 60W lamps, a dimmable version is available. Output is 100lm/W with a 25,000-hour life. The Philips clear LED A60 40W-equivalent lamp (6W) has a 470lm output (78lm/W). With an omnidirectional distribution, it has a specially designed lens for the filament-like effect. Colour temperature is 2700K and life 25,000 hours (above right). The Sylvania 10.5W GLS Omni-Directional lamp (below) was developed with Juice Technology and has a ‘ring of light’ that allows 360-degree light distribution. Light output is 806lm, equivalent to 60W incandescent. The range will be extended to 75W and 100W incandescent equivalents during 2014.

Colour temperature is 2700K, the base is E27 and lifetime again 25,000 hours. www.megamanuk.com www.lighting.philips.com www.havells-sylvania.com

Toshiba 1W and 0.6W LEDs According to a report issued at the end of last year by USbased analyst IHS, nearly half of all gallium nitride (GaN) LEDs will be produced on silicon substrates (GaN-on-Si) by the end of the decade. That would mean that some 40 per cent of all GaN LEDs were being manufactured on silicon, which compares with 95 per cent of them being fabricated on sapphire wafers in 2013, and only one per cent on silicon.

The chief advantage is cost. Silicon wafers are available in smaller sizes and are more abundant than sapphire.

So far the challenge has been overcoming the physical problems resulting from the lattice mismatch between the GaN-based light-emitting layers and the silicon substrate.

Toshiba, already involved in silicon-based manufacture, is one of the companies that claims to have resolved that. It has two new series of white LEDs, the 3.5mm x 3.5mm lens package 1W type TL1L2 series, and the 3mm x 3mm flat package 0.6W type TL3GB series.

Both have been developed as light sources for general lighting applications, including street lights and floodlights.

Luminous efficacy for the TL1L2 version is 135lm/W (5000K, Ra70) at 1W operation, and 118lm/W (5000K, Ra80) at 0.6W operation for the TL3GB-Series. There are six colour temperatures ranging from 2700K to 6500K. Mass production started at the end of March. www.toshiba.co.uk Osram PrevaLED Linear Flex

Sylvania TruColour CMI lamp Whatever the realities of the marketplace, no Martian landing in Frankfurt would have guessed that anything but solid state light sources existed. So rather refreshing to come across Sylvania’s TruColour CMI lamp, which, according to the company, features cutting-edge performance in ceramic halide technology. With a CRI of 90-plus, the new range of lamps has a red rendering which is almost four times better than similar lamps on the market, says Sylvania. With a lamp life of 20,000 hours and luminous efficacy of 110lm/W, it is available in 3000K and 4200K. While the main thrust for the lamp is the retail sector, Sylvania has also launched a TruColour CMI-TT version for street lighting applications. www.havells-sylvania.com

Osram’s answer to the LED strip, Prevaled Flex Linear is supplied on a 28m roll, and can be cut to length and bonded into the luminaire. It also allows curved shapes for more organicshaped luminaires. www.osram.co.uk

Samsung Smart Bulb Among several smart lamps on show, Samsung’s lamp uses Bluetooth rather than wireless, eliminating the need for a bridge and wireless AP, so it can be controlled directly from a smart device. By installing a special app, users can control up to 64 lamps with no additional kit or set up needed. The Smart Bulb can be dimmed down to 10 per cent and is tuneable from 2700K to 6500K. www.samsung.com/us/appliances/led-lighting

Exhibition review

INTERIOR LUMINAIRES iGuzzini Trick A stand-out at the show, this luminaire is mainly about decorative lighting effects and comes in three basic versions: 360-degree radial, washer and Light Sliver optic effect.

The really clever one is the third option which produces a

stripe of light on all four planes from one fitting (360-degree version). The 180-degree version does it on three planes, except the surface on which it’s located. This also makes it a nifty fitting for window reveals. It can be either ceiling or wallmounted and comes in 2.9W and 5.8W warm white options. www.iguzzini.co.uk Trilux Lateralo Plus The devil is in the detail and while there is more than one oblong, transparent (in the off-state) suspended luminaire on the market, minimalists will appreciate the lack of wiggly wiring that so often mars the effect – the power feed is through the suspension cables. The fitting comes in two

sizes, 340mm × 1176mm × 14 mm and 340mm × 1455mm × 14mm, and output ranges from 6000lm to 9000lm (100lm/W). LEDs are located either side and light diffused

by Trilux’s Binary Light Guide System prism technology. The ratio of direct to indirect light is 50/50. Colour temperature is 4000K (RA>80) with other temperatures on request. www.trilux.com/uk/

Lucent ProSpex LED50 Ambiance Warmdim XAL Sasso Midi CWD When it comes to LED lighting approximating halogen there have been several difficult nuts to crack, one of which is replicating the increasing warmth of halogen as it dims.

This issue was tackled by two companies, UK-based Lucent with this latest option for its ProSpex range (below), and Swiss manufacturer XAL. The Lucent

ProSpex downlight has LEDs of two colour temperatures, 3000K and 2200K. As the luminaire is dimmed, the first LEDs diminish in level while the 2200K ones are brought up, with no loss in CRI. It’s compatible with most dimming protocols. XAL has used the same principle for the Midi Series of its new generation of Sasso accent fittings (above).

With the CWD (colour warm dimming) option, light intensity reduces simultaneously with a progressive temperature change from 3000K- 2000K. www.lucent-lighting.com www.xal.com

Philips Lighting OneSpace The single glowing surface is becoming a reality with or without OLEDs. The OneSpace luminous ceiling integrates a mesh-like arrangement of LEDs with a textile.

No other ceiling is needed as the luminous plane plays the dual role of ceiling and light. The panel, which comes in customised sizes up to 10 x 3m, is also sound absorbent. It can be dimmed, used as safety lighting and also be connected to building management systems. It is especially suited to car showrooms (no hotspot reflections), retail stores and public spaces such as airports, hotels and conference facilities. www.lighting.philips.co.uk

Exhibition review Flos Architectural The Black Line

Difficult to glean from photographs, the glare control and discretion of The Black Line have to be seen to be appreciated. It’s as close as dammit you can get to lit effect without visible luminaire for a fitting out there in the ceiling as opposed to concealed at the perimeter. The lit effect can also be controlled, from a soft flood width to a stronger, sharper effect according to the version selected. A combination of multiple LED spots provide a homogeneous downlight. The core of the system is a combination of specially designed silicon cones which cover each LED module, providing maximum cut-off to reduce glare and at the same time control the shape of the light, in narrow or flood beam. The geometry of the lens integrated in the cut-off cones contributes to the virtually glare-free result. The range comes with two, four, eight and 12-spot options, both for accent and general lighting. www.flos.com Fagerhult Indira

Delta Light Forty-5 Delta Light had its usual mix of highly useful fittings (such as the iMax Soft Ceiling range) and a few quirky decorative ones. The Forty-5 wall fitting falls in the second camp. It plays an optical trick according to the viewer’s standpoint. A cube on paper consists of two overlapping squares, with the corners joined by four lines at 45 degrees – hence the name.

The fitting is available in two versions each forming the mirror image of the other. Finish is white, with both LED and driver integrated and hidden in the fitting. www.deltalight.co.uk Ribag Oviso We really aren’t there yet for OLEDs in terms of commercial pricing apart from anything else, but that hasn’t stopped Ribag bringing out a whole range which includes horizontal and vertical pendant lamps, and a wall lamp (shown). The wall version has an output of 250lm and colour temperature of 2700K (CRI >92). Length and width are 331mm x 153mm. ribag.com/en/products/oviso

Fagerhult has produced a classroom LED lighting system based on new research findings highlighting the importance of ambient light in the study environment. Indira, specially developed for a study in collaboration with Lund University in Sweden, is based solely on ambient lighting.The company’s research has previously found a positive influence on pupils in rooms with a high proportion of indirect lighting on the walls and ceiling. The findings also indicated that LED lighting was perceived as brighter than T5. The results, according to Fagerhult, showed that the system provided 33 per cent more light at 13 per cent lower power consumption (8W/sqm). The system comprises three different types of luminaire, all of which can be mounted on Fagerhult’s iTracks system: a wallwasher, a combined wallwasher/ uplight and a pure uplight. The fixtures are based entirely on providing indirect light. The installation only has one electrical connection point and luminaires can be moved or added to according to need. www.fagerhult.co.uk

Exhibition review

SPECIFIER’S SELECTION

Iain Ruxton, design associate at Speirs and Major, picks out his Top 10 products at L+B

Light and Building was an interesting show this year. There was very little that had me telling any acquaintance I met that they had to go and see it, but there was lots of good stuff in a quieter way. As LEDs continue to mature, it is clear that diodes are improving steadily, incrementally and not very interestingly. Everyone worth their salt has got the hang of thermal management, drive electronics and diode selection… the innovation at the moment is in what goes in front of the chip. The most interesting spaces in lighting for me right now are: modules with designed output spectra; optics; controls.

Anyone you ask will have a different Top 10, depending on their particular interests or needs, and I freely admit that I didn’t visit every stand in every hall. Perhaps there was a gem buried deep in the general terror of Hall 10 that I missed. But here, in no particular order, are my favourite spots from Light and Building 2014.

Xicato XIM Module Xicato stay one jump ahead by combining its proven colour technology with on-board intelligence.

Moving the drive on board so you only need a bulk 48V supply is great, but the awesome bit is building in various sensors, any control protocol you can think of, and potentially an open software development environment for OEMs to play with. Thermal self-management and accurate reporting of consumption, run-time, light output and so on is only the beginning with this range. Inter-module communication, processing of multiple sensor inputs, connectivity to pretty much anything else… the potential is outrageous for different companies to implement all sorts of ideas with this platform. I can’t wait to get my mitts on one and geek out big time. Oh, and you want smooooooth dimming right down to nothing? Oh yeah… it gives you that all right. www.xicato.com Helvar/Fagerhult e-Sense Tune This was so new and ‘beta’ that I’m not sure Helvar/Fagerhult even had a proper name for it at the show, but this takes the idea of controlling lights from your phone and makes it into something useful instead of a gimmick that no-one wants. Take your phone out, tap in your password, fire up an app and fiddle around just to put lights on? Sod off. People want buttons on walls. However… what Helvar has done here is take

Lighting Journal May 2014

the relatively straightforward ability to do that and added a smart bit of thinking. With this system, you set your preferred lighting conditions once on your phone via Bluetooth, and save it into the lights. When you return to the room, the system detects your phone when the Bluetooth reconnects and recalls your settings. If I turn up instead, it recalls mine.

It’s like the BMW keyfob that remembers how you like the seat and the heating. Smart. www.helvar.com iGuzzini Laser Blade Wallwash

Laser Blade was one of the clever things at L&B 2012, putting some great optical design in front of LEDs to make a downlight that works, but has a really quiet and classy appearance in the ceiling. Very low glare yet still efficient enough. Now iGuzzini has come up with a wallwasher in the Laser Blade family which creates a great wash from a tiny footprint widely spaced. Job done. www.iguzzini.co.uk XAL Disc-O OK… it’s a glowing disc (one of the ubiquitous forms of the show this year) and not brand spanking new, but XAL has differentiated here.

As an object it’s a perfectly fine glowing disc, but what is really well executed is the constant lumen output tech inside. Start by under-running the LEDs, then slowly ramp them up as their output naturally declines… if the algorithms are right you deliver genuinely constant lumens over the 50,000-hour life. They’re not the only people to think of this, but they’ve done it really, really well www.xal.com Norlight (Castaldi) Aperio File in the ‘I love it but I’m not sure what to do with it’ section, but it certainly caught my eye.

A motorised, wall-recessed linear light sounds like a crazy idea, but this thing works really well and looks great. Invisible when off, sharp and tidy when on, and entrancing when on the move. I defy you not to smile when you see it working. www.castaldilighting.it

Exhibition review Castaldi SLED Having clearly come back from a difficult period with all guns blazing, Castaldi impressed me with another product too. The SLED is a neat little module combining LEDs, optics, mechanical assembly, electrical interconnect, heatsinking and IPrated packaging in one plug-and play unit. There’s a good range of optics, two sizes/powers, and a choice of cool, warm, RGB and dynamic white.

Beyond that, it’s up to you… buy these at a very reasonable price and make something, in the knowledge that everything is taken care of. All you need to make them work is an appropriate driver. It’s not an LED module in the usual sense… it’s a building block for creating lights. www.castaldilighting.it Meyer Ground Recessed 3W LED Uplight This might not sound like much, but a small adjustable LED in-ground spotlight with a single diode and a really good lens, with integral driver and everything done right is a really useful tool that isn’t easy to find. It may not be the only one on the market but I like it a lot… and you’ll have to hunt around for another one that gives you a beam as narrow as four degrees. There’s a 13 degree too, and they’re both cracking. www.meyer-lighting.com www.commercial-lighting.co.uk Soraa AR111 Soraa has impressed many of us with their Gan-on-Gan LED MR16 substitutes. Now they’re carrying on into the tricky R111 form-factor and were demonstrating a prerelease unit with a nice clean beam, tight field and very low glare, and in beam angles down to eight degrees. The first LED AR111 I’ve seen that looked like a proper AR111 in terms of beam and glare. Shuji Nakamura’s team seem to be going from strength to strength in this market, and let’s face it… if anyone knows what they’re doing, he’s got to be on top of the pile. www.soraa.com

Ingo Maurer Flying Flames

It’s always worth braving Hall 1, if only to see what witty creations Ingo Maurer has come up with. I think there was a version of Flying Flames at the 2012 show, but as a full system it is lovely. Yes, it’ll be expensive and yes, you’ll only use it once but what a joy. Abstract circuit-board candles with a tiny low-res LED matrix showing a flickering flame. The candles are combined with simple and functional downlight elements and both can be placed freely with a magnet on the canopy board. As always with Herr Maurer, it’s half-light and half-art, and this one is a delightful comment on the history of lighting technology. www.ingo-maurer.com NDF Caret Squirrel-Cage Lamp Lastly, another replacement lamp… an oddity that I like a lot. The incandescent squirrel-cage lamp is ubiquitous in restaurants and bars all over and much loved. The warm, low-tech appearance has a classy comfort to it, even though it doesn’t do a lot as a useful light.

The march of energyefficiency legislation will see them gone before too long, even though lumens/watt isn’t really a very relevant thought here. Anyway, NDF has come up with an imitation using miniature cold cathode which may look a little odd when off, but when on is pretty convincing, enabling all those bars to carry on with the look. It’s dimmable, it looks right, it’s class A efficiency. My only wish would be that they make an even warmer one – the incandescent lamps are usually dimmed a lot and really orange. Drop the 2300K to 1900K and you’ve really nailed it… www.ndf.eu

Street furniture

Part of the furniture Francis Pearce looks at integrated exterior lighting

I

ntegrating lighting into street furniture can help authorities remove clutter from pavements and roads, and has advantages such as reducing light spill and improving the look and feel of public spaces.

However, customisation is generally the best approach, and it is seldom a good idea to simply retrofit lighting to existing equipment.

‘Being able to add lighting into a number of urban elements, such as furniture and railings, has led to specifiers making more use of the greatly expanded tool box,’ says David Anstee, DW Windsor’s business development manager for urban furniture. However, ‘a successful solution for merging furniture and lighting is unlikely to be achieved by simply specifying an item of furniture together with a light source.’

Among other issues, ‘light sources tend to be positioned relatively close to the illuminated surface which makes

the choice of source more difficult both in terms of selecting the required brightness and avoiding hot spots.’

Illuminated and illuminating street furniture, from traffic signs through to benches and bus shelters, are components of the lit townscape and the public realm whose design is as important by day as by night. Over recent decades, though, ambient light levels have generally risen in town centres with greater illumination of shop frontages, restaurants, petrol station forecourts and advertising hoardings.

Traffic signs have to compete with these in order to be seen easily but a move to LEDs and designs that provide a more even distribution of light across the sign face have helped authorities avoid a lighting arms race in city centres. Likewise, benches, railings and shelters can be lit at levels that contribute to safety, amenity and the atmosphere of public spaces without blasting them with light, and

Garda LED handrail by DW Windsor (above) and the company’s Vaio seating (right)

leaving enough shadow and shade for facade and monument lighting to be effective.

‘Good scheme designs require contrast and visual texture. The possibility of incorporating lighting into street furniture has recently become more achievable due to advances within light source technology: predominantly LED. The size and robustness of LEDs allows integration into smaller spaces offered in street furniture,’ say Anstee. ‘More sophisticated LEDs give directional light, reducing light spill and avoiding the need to flood an area from a high column. Being nearer to ground level allows maintenance to be carried out more safely and easily, without the need for high-level access equipment.’

CIS Street Furniture, whose products extend from bins and bollards through to lanterns, has a range of cast and ductile iron, and resin-bound steel tree grilles that can

incorporate LED uplights. As they can fit flush with the ground they can be used to light benches, low walls and trees, in particular, without wasting valuable real estate. Landscape architect Gillespies chose CIS Street Furniture’s cast tree grilles for Woking Town Centre, both for visual impact and because they are tough enough to cope with a car mounting the kerb.

These and other physical design

considerations such as vandalproofing make integrating lighting into street furniture a challenge.

‘A bespoke solution takes into account finished levels, so accurate surveys and onsite collaboration with other trades such as paving and cladding are required to ensure the smooth running of such a project,’ says Anstee. ‘Many of the most suitable light sources are designed

33

for in-ground applications, in that they are robust and adequately sealed.

However, they are also expensive and may not have the required lighting distribution, having been designed for a different lighting application.

‘Solutions originally designed for in-ground applications may also have limitations in terms of the lengths available,’ he continues. ‘While it’s possible to cut LED strips to any size they typically require additional seals and protection to make them sufficiently robust. The addition of in-ground chambers and feeder pillars to allow for isolation and the installation of drivers can also add significantly to the overall cost of a project. The best solutions are designed specifically for the application, providing even and defined distributions calculated as part of an overall lighting scheme.’

Anstee cites the company’s own Garda illuminated LED handrail, an increasingly widespread approach, whose electrical design allows runs of more than 100m from one power feed to simplify installation. The transformers can be located away from the handrail and electrical cabling can be integrated safely within the system at low voltage (24V to 48V).

Street furniture

There are times, though, when integrating lighting into street furniture is simply about creating a sense of fun and making visitors welcome.

UK street furniture company Falco recently manufactured and installed a futuristic space-shuttle style bench, with built-in solar-powered LEDs, in Almelo in the Netherlands. It was constructed in partnership with Dutch designer Dynteq, from FSC hardwood slats and powder-coated steel. The rear of the bench has three red W-shaped LED luminaires representing the rocket engines of the space shuttle and powered by solar energy cells built into the ‘nose’ of the bench. The LED lights can also be lit by turning the handle at the back

of the bench, which commemorates Dutch astronaut Wubbo Johannes Ockels’s space flight in 1985.

Thanks in part to LEDs, lighting’s integration into street furniture is accelerating but in future the lighting may itself also be integrated with intelligent technologies such as CMS, near-field communication and geo-fencing. ‘In its simplest form this could mean fitting a charging port to a bench; allowing users to top-up their phone’s battery while they sit and read the latest news they just downloaded from the WiFi or 4G access point integrated into a nearby monolith sign,’ says Woodhouse marketing manager Mike Clay.

‘This gives us a glimpse of the bus shelters of the

Lighting Journal May 2014

future. The lighting would be remotely controlled and monitored to track energy consumption with presence detection to adjust lighting levels down when there is no one waiting for the bus. Taking this one step further means that the street furniture could be configured to react to individual user needs; for a Mexican tourist a bollard may describe, in Spanish, the history of that locality and that same bollard might simply give audible reference directions to a blind person.

Head down the street and an LEDilluminated bollard might get brighter to help a partially sighted elderly woman see the steps down to a pelican crossing that senses her presence and give her longer to cross.’

Paving the way

Pedestrian crossings take a step forward with a new intelligent system

T

ransport for London (TfL) is to trial a new intelligent pedestrian crossing this summer. Called the Pedestrian Split Cycle Offset Optimisation Technique (the acronym, Scoot, is snappier), it’s part of a £2bn-£4bn programme to improve the capital’s roads over the next 10 years and cut traffic fatalities by 40 per cent by the year 2020. The programme has recently seen the introduction of Pedestrian Countdown technology which was rolled out in 200 locations.

Hailed as a world first, the technology is based on the Vehicle Scoot system developed by the Transport Research Laboratory in collaboration with the UK traffic systems industry, which uses sensors at intersections to gather traffic data, together with a computer system that adjusts light timings to allow traffic to flow as efficiently as possible.

So far the vehicle system has been installed at 3000 junctions, with plans for 1500 more by 2018. It caused controversy during the 2012 Olympics when it was programmed to allow official vehicles to move through the capital more quickly.

The aim of the pedestrian version is to time the changing of the lights more efficiently so that as many people as possible are able to cross, while keeping the traffic flow as smooth as possible. Although the lights should be timed to allow everyone to cross safely, pedestrians don’t all cross in one lump and stragglers can be left making a dash for the other side. The flip side of the coin is that pedestrians pressing the request button often then cross against the lights or change their mind, either of which creates unnecessary traffic delays.

Scoot uses video cameras to count the number of people in a digital box on the crossing pavement. If it detects a large number of people, the system alters the timing of the green walk light to allow more people to cross safely. If

no one is at the crossing, or someone pushes the button and then crosses against the lights or walks away, the system switches to ‘call cancel’ and doesn’t activate the walk light.

Reductions in vehicle delays approached 20 per cent at earlier test sites, say the developers, ‘but the benefits to pedestrians will be limited when the vehicles flows are high’.

A further pedestrian safety measure is the puffin crossing design.

Unlike older pelican crossings, where the walk signal is displayed across

the road, the signal is displayed above the request button. This forces pedestrians to look in the direction of oncoming traffic while waiting for the light to change, so there is less chance of them stepping off the kerb in front of an oncoming vehicle.

The Pedestrian Scoot system will initially be tested at high-traffic crossing areas, with the first ones installed outside Balham and Tooting Bec Underground stations. www.scoot-utc.com

38 Conference report

Looking up Down Under Australia and New Zealand look to get into the LED fast lane.

Nigel Parry reports on a new road lighting event in Auckland

A

new lighting conference and exhibition has emerged in New Zealand. Held in March in Auckland, the event was organised

by Strategic Lighting Partners and attracted speakers from across the globe, with around 30 exhibitors and more than 220 delegates. The packed two-day programme focused on experiences from across the world, including the UK, USA, France, Canada and Norway with, of course, local speakers from both Australia and the host country.

Officially called Innovation, Efficiency and Safety, the bold working title was ‘Arm yourself for the lighting revolution’. Day one started with wellknown figures from road lighting in the US, with Ed Ebrahimian updating everyone with the latest from Los Angeles. He reported that in rolling out around 140,000 LED luminaires, they have only had 400 faults in the past four years, none of which were LED chips. He had also tested some of the first LED units installed for light output and found that after four years there was zero dirt depreciation. It was a point that was discussed and should provide evidence for future updates of luminaire depreciation tables.

The next speaker, Dr Ron Gibbons (the new CIE Division 4 director), outlined his current research on road driving safety and advised that if texting while driving we are 23 times more likely to have an accident.

The New York programme for changing 250,000 lights to LEDs was explained by Margaret Newman.

Both her story and Ed Ebrahimian’s had similarities, in that it seemed the

Lighting Journal May 2014

process involved a natural evolution to LEDs rather than it being a bold transformation.

Finally, Ed Smalley from Seattle described a policy of information sharing on street lighting inventories and light levels across all except three states in the US. This was proving valuable in helping everyone to understand what is required, he said, and also enables the smaller authorities to buy at the same price as the larger ones. A methodology we should consider in the UK. There were a few exceptions to the LED theme, such as Richard Webster, Suffolk CC lighting manager, who outlined the CMS route the county had taken to control the lights and as part of which they switch off from midnight to 5am (see Lighting Journal October 2013). He informed the audience that one unforeseen additional benefit was that reported crime figures had dropped.

There were several papers on LED success Down Under with Paul Gowans (an expat from the UK), principal engineer electrical and furniture for Sydney, demonstrating how the city was ahead of the curve and had already transformed the centre with LED technology that was both energy saving and providing higher light levels.

Day two started with myself and Alistair Scott outlining the tsunami of change being seen in road lighting in the UK, with moves to both LED

and CMS technology, and how a flexible approach by the standards committee has been a significant catalyst for this change.

This was followed by an outline of the various options for finance and procurement that are available to the local community, noting that the local standards in Australia and New Zealand – AS/NZS 1158 series: Lighting for Roads and Public Spaces – need to change and change quickly to allow the take-up of both LED and CMS technology within the next two years.

To conclude the conference the organisers held a roundtable discussion with all the speakers participating and taking questions from the audience.

In summary, the conference was centred on the speakers advising the Australians and New Zealanders that it is safe to get into the LED fast lane and how to do it. There was a natural concern by the local attendees that LEDs won’t live up to their promise and CMS was perhaps just too much icing on the cake.

The conference organisers were keen to dispel such beliefs, and as such the programme was delivering the information and confidence that was required. Following the conference there was a great deal of discussion, and perhaps all that is missing is the government backing to allow the revolution to take place.

This was a road lighting event with an appetite to learn and adopt new ways, and it was a refreshing change to see the level of participation of all those attending. I hope it is repeated at some point. http://roadlightingconference.com/ events/conference/

costs and hassle for all local authorities, and I would strongly recommend that it is supported by all ILP members – let’s make sure our voice is heard.

The Lanterns project (Local Authority Collaborators’ National Evaluation of Reduced Night-time Streetlight) is progressing and has already produced some promising data. Again, I would encourage members to participate. Your local DNO may even be able to provide the data required on your behalf and so it may require less LA resources

protected Excel spreadsheet. It will hopefully act as an interconnected network for communicating with and informing members. I would appreciate any comments on improving it.

It is always useful to get feedback on particular experiences and incidents, for instance. A recent court case on commuted sums is a good example. In a time of budgetary restrictions, commuted sums are another way for local authorities to ensure availability of funds when new developments are adopted. One developer took the local authority to court for charging this commuted sum. The local authority won the case but the developer has appealed.

Comments are welcome.

A couple of imminent introductions that members should be aware of. I am on the Unmetered Supplies User Group (UMSUG), a working group that meets quarterly at the Elexon offices in London. Please note that the last of the current Elexon load research is due for implementation this month.

Phase 3 should have a negligible impact on most local authorities.

However, it is worth checking the impact on your budgets (Phase 1

to participate than some may have previously thought. This worthwhile project benefits all of us, helping to improve our understanding of lighting and the decisions we make.

As a local authority street lighting officer, I find attending regional ILP events and sharing experiences help me to do my job effectively, making problem solving more constructive and positive.

Another helpful ILP resource in this respect is The Grid, which has proved a good reference for members.

A simple way of identifying who’s who in highways and infrastructure lighting, it gives contact details and helps you keep in touch with public lighting peers. Available free of charge to members logged into MyILP, The Grid is downloadable as a password-

came into effect April 2012 and Phase 2 April 2013). Please contact your meter administrator or distribution business if you need more information.

For many authorities the Carbon Reduction Commitment (CRC) Energy Efficiency Scheme Phase 2 started on 1 April. If your authority qualifies you must report all of your unmetered supplies. Some authorities in England will no longer qualify for the CRC due to the removal of schools from reporting requirements. It is worth checking whether your authority is still in the CRC scheme.

We can make a difference. We can learn from experiences. We can contribute to shaping the future of our industry only if we have a voice and are involved. Let us work towards leaving our footprints for others to follow.

orking smarter has been the theme in local government for some time. This has led to a different workplace ethos and innovations such as hot desking. Then along came ‘restructuring’ as part of an efficiency drive, followed by a realignment of objectives aimed at delivering savings through reduced resources. These are still tough times for all.

In this context, informing, communicating and supporting our members has been the key objective of the ILP highways and infrastructure team. This is an evolving portfolio which involves working closely with other groups and individuals in order to achieve its purpose.

Since the workshop held at the national summit with independent distribution network operators (IDNOs), many regions have had discussions with their local host distribution network operator (DNO) to resolve issues arising with identifying assets, energy payments, and putting in place a protocol to encompass probabilities. Regular updates have been published in Lighting Journal (see November 2013 and March 2014 issues). YALE (Yorkshire and Lancashire Engineers) group and the ILP North East region each held workshops tailored to their particular issues last month.

As set out in the informative recent Journal articles, the original Elexon Draft Change Proposal details for DCP168 had to be withdrawn. It is anticipated that this will be reopened for comments again shortly.

Ofgem (Office of Gas and Electricity Markets) has requested the participation of all local authorities in this in order for the consultation to prove worthwhile. This is a good opportunity to remove administrative

specifiers, planners and engineers with innovative and exceptional design solutions for public spaces. A reputation of excellence has been built over 25 years for delivering bespoke designs, in-house and partner products.

Projects include urban landscapes such as the London Canary Wharf financial district, innovative lighting columns for Exhibition Road in London’s Kensington, bespoke internal and external signage for Cabot Circus Shopping Mall, Bristol, an iconic 9m high LED illuminated monolith sign in Newport, Wales, and hosts of other waterside, city street, campus, shopping mall, prestigious commercial and public developments.

Woodhouse offers four of its own coordinated street furniture, lighting and signage ranges: Loci, Coda, Geo and Motis (a modular shelter system). These ranges include the innovative Coda LED street lighting luminaire which achieved Commended status in the Lux Awards 2013. The business also represents four European partners: Escofet – iconic urban furniture elements; Aubrilam – beautiful and sustainable timber lighting columns; Eclatec – striking and high-performing French street lighting luminaires, and LEC Lyon – leader in architectural LED lighting solutions. iGuzzini With the LED Underscore lighting programme, iGuzzini devised a new graphic way of using light: just a few millimetres of light to emphasise details and define spaces.

Integrated into the architecture, the flexible linear white LED strip can be used to identify routes and obstacles, highlight textures and create a mood in a space.

When applied to surfaces in spaces with a low light level, the system creates curious effects and visual illusions.

With the latest Underscore6, designer Dean Skira has created a new, innovative aluminium profile system with extremely compact dimensions – only 6mm, the smallest of its type on the market, designed to create very thin, homogeneous lines of lights and luminous effects.

When a line of Underscore6 is integrated into a corner, for example, the effect is an illuminated gap, where the surfaces are contiguous but appear not to be joined.

The Underscore range includes two recessed versions for planar surfaces, two recessed versions for internal and external corners, and two versions for wall/wall-mounted applications. It comes in three colour temperatures: warm, neutral and cool. The profiles have a silicone elastomer thermoresistant protection coating to guarantee high elasticity and avoid cracking.

Orangetek Orangetek understands how national and international research has helped develop our lighting standards and established the UK as perhaps the leading country in the world in early adoption of LED and CMS technology. This forward-looking approach is enabling lighting professionals to enhance road lighting across the UK, achieving the right light, right place approach and contributing to halving UK street lighting energy use by 2020. The ILP Professional Lighting Guides are a key part of this process and we are proud to support even in a small way the continued excellent work that the ILP committees do in providing guidance and first-class training.

Technology keeps moving forward and in keeping with our approach of providing affordable, high-quality luminaires, we are launching our new TerraledMini. This has all of the great Orangetek Terraled range advantages, of classleading thermal management, flexible mounting and tilt (-10 to +10), LM6 marine-grade aluminium with a fully painted body and IP66 protection, but is half the size. The luminaire has a single LED array, provides lighting to meet the P3-P6 classes with narrow, medium and wide lenses available, and is probably one of the lightest available at just 5kg.

Light on the past:12

Something useful found by accident Simon Cornwell on late-night shenanigans and the first commercial lantern for a discharge lamp

I

t isn’t known if the residents of Watford Road, Wembley, reported any of the late-night shenanigans that took place in March 1933.

Several nervous-looking men turned up in the early hours and proceeded to act very suspiciously.

But instead of the expected jemmies and bags labelled swag, they were armed with baffle plates fitted with louvres. And any pretence of operating under the cloak of darkness was quickly lost when the men activated the new street lighting system, washing the road and buildings with a strange blue-green hue.

They were obviously connected with the new street lights in some way, but the official opening by Captain JM Donaldson and council dignitaries wasn’t due for several days. Then, to add to the residents’ confusion, the men (now looking much happier) took photographs, switched off the new lighting and disappeared into the night.

These late-night sorties were by the lighting engineers of the General Electric Company (GEC) secretly testing out a new lantern. The new mercury discharge lamp developed the previous year had been successfully trialled, but converting it for road lighting had led the engineers to despair. They felt the new problems it presented were insurmountable.

The lamp burned hot and readily transmitted heat to its surroundings (more than a tungsten filament lamp). It also had to be mounted vertically which caused two potential problems. First, there was the difficulty controlling the vertical distribution of light and the associated problem of glare. And secondly, there was need to supplement the dark area below the lantern thanks to the low intensity emitted in a downward direction.

The engineers at GEC therefore started from first principles, wiped the drawing board clean and designed a new, unconventional lantern to try and fix the problems caused by their revolutionary new lamp.

The lantern would have to be large, maximising heat loss by convection and allowing the long lamp to be placed at the centre of the optical system. The lamp’s length would necessitate the use of heat-resisting glass-plate refractors. And the potential dark area below the lantern could be fixed by a secondary reflector system of top enamel reflector, sidereflecting end-plates and large diffusing

Lighting Journal May 2014

base. Column fixing would have to be a novel design as condensation dripping down a conventional bracket would destroy the hot lamp. But, reluctant to simply create a box, the designers fashioned filleted end-pieces and chamfered canopy, giving the unit an art-deco flourish.

Luckily GEC now had several years’ experience designing and manufacturing its own glass refractors and was able to create experimental plates. It was quickly discovered that any attempt to modify the lamp intensities in a vertical plane resulted in a patchy road appearance, so they simply designed a refractor plate with vertical grooves to spread the light in plan and hoped the glare would be tolerable. As a precaution, baffle plates were also manufactured if the installation was a disaster, but all were reluctant to use them as they would have been unsightly and resulted in a patchy distribution and pools of light.

They had far more luck with their secondary reflector system and the light cast below was enough to prevent a dark patch appearing. The combination of refractor plates for the main beam (such as it was), diffusing end glass and diffusing base produced a plan distribution that was adequate for the general illumination of roadway, pavements and building fronts. The bracket design was also easily solved.

Rather than adopt a top-entry system, the lantern was bolted to the column using four side-entry sweeping bracket arms. It allowed the lantern to be aligned accurately with the street and securely locked into position without the possibility of condensation running into the lantern from the bracket arm.

But it severely limited the overhang.

The first installation was close to GEC’s research labs in Wembley.

With the cooperation of Captain JM Donaldson, the North Metropolitan Electric Supply Company and the Wembley Urban District Council, the new lantern was installed along Watford Road in Wembley. Having already used the name ‘Wembley’ for a range of lanterns with dome refractors, the firm christened the lantern after the road.

But having solved many of the issues surrounding the lamp, the firm’s engineers were still extremely doubtful about the amount of glare. Convinced that the inauguration ceremony would be a disaster, they grabbed their baffle plates and crept out into the night to

The polar curve of the GEC Watford (above) through the vertical plane of maximum intensity.

It met many of the characteristics of the later ‘non-cut-off’ distribution: flat toe-in (for good illumination below the lantern), high peak angle (for creating the important ‘streaks of light’ on the road surface) and relatively slow run-back above the horizontal (for control of glare)

secretly test the installation before the big switch-on.

To everyone’s amazement, the installation was successful beyond their expectations. The lanterns produced a high degree of visibility with no material glare whatsoever.

Waldram, who had learned to study the exceptions (particularly after the 1928 APLE conference) declared that ‘something useful had been found by accident’. The unused baffle plates were quietly thrown away.

If the residents of Watford Road thought they’d now be left in peace then they were wrong. The same team of men turned up again in the small hours, not armed with baffle plates, but instead with cardboard cut-outs of cats. The long-suffering residents would probably have simply drawn the curtains and gone back to bed. But for Waldram and his team, Watford Road offered a golden opportunity for finally discerning the ‘mechanism’ and determining how this installation actually worked.
