70 years of lighting knowledge!

Dear Reader, In this issue of the Innovator we celebrate the 70th birthday of Fagerhult. When discussing what these 70 years represent the answer came quickly – 70 years of lighting knowledge, 70 years of innovation with focus on creating light that is good for people. This knowledge and innovation journey started with our founder, Bertil Svensson, wanting to give his mother the experience of doing her handicraft in good lighting. What began with a smartly designed floor lamp became our DNA. Our curiosity, innovative mind-set and the knowledge we have built over the years have prepared us for any challenge to come. Challenges in new technologies, new materials and new findings.

The past few years we have seen a paradigm shift

within the industry that can be summarised with three letters and is spelt LED. As the earth keeps spinning, time doesn’t stop and we keep looking into the future to find the lighting solutions of tomorrow. What are the trends in lighting, what is the next step and when?

In the meantime, we see more and more new tech-

nologies to exploit the fact that LEDs are electronics and that we are able to use the lights and electronics for more than just lighting. For those who dare to look up and think in new patterns, the possibilities with new technologies become greater than the limits.

Connectivity is here to stay and it is growing fast. As

a result we see the development of smart cities and smart buildings where the lighting system, its electronics and sensors are essentials part of information network. This is happening now and constantly evolving, faster than anyone could have imagined just a couple of years ago.

So happy reading to all you innovators!

Lighting represents almost 20 percent of global electricity consumption according to the International Energy Agency. The future development of society in both developed countries and emerging economies around the world are intimately tied up with the ability to effectively light our cities, workplaces, homes, schools and recreation areas. text klas andersson | photo fagerhult, istock photos

Lighting provides safety and security, provides access to education, enhances architecture, and improves our quality of life. We take it for granted and often notice it only by its absence. However, as cities worldwide develop it is essential to employ new and innovative lighting design techniques and technologies that improve energy efficiency cost and control, that easily can be adapted to local needs. light is not only visual Light plays a vital role in our daily lives and is an imperative cross-cutting discipline of science in the 21st century.

It has revolutionised medicine, opened up international communication via the Internet, and continues to be central to linking cultural, economic and political aspects of the global society.

On 20 December 2013, The United Nations (UN) General Assembly 68th Session proclaimed 2015 as the International Year of Light and Light-based Technologies (IYL 2015).

This International Year has been the initiative of a large consortium of scientific bodies together with UNESCO, and

international year of light 2015

will bring together many different stakeholders including scientific societies and unions, educational institutions, technology platforms, non-profit organizations and private sector partners.

The Global Secretariat is located at the Abdus Salam International Centre for Theoretical Physics in Trieste, Italy.

In proclaiming an International Year focusing on the topic of light science and its applications, the United Nations has recognised the importance of raising global awareness about how light-based technologies promote sustainable development and provide solutions to global challenges in energy, education, agriculture and health. light as a drug Light has been known for a long time to enable sight, safety and orientation. But light can do more than enable vision.

Light has the power to energise, relax, increase alertness, cognitive performan-

ce and mood. Light is the most powerful regulator of the day-night-rhythm of people. Every day light exposure adjusts and stabilises the duration and timing of our sleep-wake cycle. Moreover, light is known to be an effective treatment for a variety of conditions that include mental disturbances such as Seasonal Affective Disorder (SAD) and certain kinds of sleep disorders.

The ability of light to achieve these various non-visual effects depends on the spectrum, intensity, and temporal pattern of the light, as well as the light-exposure history and preceding sleep behaviour of the individual.

Therefore, the optimisation of a Human Centric Lighting solution for a given non-visual effect is only possible when this user context is accounted for. This requires a dedicated and tailor-made design, based on a profound understanding of the personal and environmental conditions of the use-case(s). A “one size fits all� Human Centric Lighting solution does not exist, and one may even do more harm than good when applying a solution beyond the context and scope it was designed for.

can you see the stars?

In most large cities of the world, it is no longer possible to appreciate the beauty of the night sky. Inefficient public lighting both wastes energy and causes “light pollution” that hides our universe from us.

“Light pollution” is a form of environmental degradation in which excessive artificial outdoor lightings,

such as street lamps, neon signs, and illuminated sign boards, affect the natural environment and the ecosystem. The wasteful light emitted directly upwards or reflected upwards from poorly-designed artificial light sources can be scattered by clouds, fog, and pollutants like suspended particles in the atmosphere.

The night sky is thus brightened, leading to a reduced number of stars visible in

the sky due to a decrease of the light contrast.

light over the world From India, Brazil and Iran, to Italy, Cuba and Senegal, throughout the course of 2015 the world will be paying their own local tributes to light with a series of events, lectures and festivals. To find out more visit www.light2015.org.

70 years of lighting knowledge Fagerhult is the story of a man who saw the world with new eyes. Who spotted opportunities in technological advancements and in the world around him. And who shared his visions with others like him. 70 years later, our driving forces are still innovation and knowledge – with a human focus. text amelie bergman | photo fagerhult

Our story begins at Christmas time. The year was 1943 and a young electrician, Bertil Svensson, had a brilliant idea for a Christmas gift for his mum. He bought an 18.6 mm light-gauge conduit, a bit of cord, a lamp holder and a mains plug from his employer. He asked a local carpenter to turn him a birchwood lamp foot, and found a 60 cm lampshade at the local department store. And then he sat down to assemble his very first light fixture.

The result, a floor lamp in the shape of a question mark, was a big hit, brightening his mother’s crafts room on long, dark winter days.

“Doing needlework by the light of a floor lamp was not very common in

70 years of lighting knowledge

those days,” Bertil said. “I didn’t spend a lot of money making that lamp, and when I saw what similar ones cost in the shops, I got the idea that maybe I could make a living making lamps.”

“That was my whole idea. I had no thought at all about organisation, sales technique or distribution.”

That would soon change. In 1945, Bertil Svensson teamed up with two childhood friends from Fagerhult.

Helmer Andersson was a clever designer and production technician at Husqvarna. Harald Ulfenborg was a furniture manufacturer under the Ulferts brand.

Together they started Fagerhults Lampindustri in an outbuilding on Bertil’s family farm in Fagerhult.

Bertil’s inventiveness, Helmer’s technological genius and Harald’s contacts in the furniture industry became the foundation of a highly successful home lighting company. It was not an easy time. Europe lay in tatters after the Second World War and it was hard to obtain materials. But thanks to its neutrality policy, Sweden was in fairly good shape, and soon its industry was running at full tilt.

In the beginning, Fagerhult focused on the home market, which was fuelled by the new Swedish welfare model.

By autumn 1947, the company had outgrown the outbuilding and it moved to a newly built 98 m² factory. Since then that factory has been renovated

“In 1948, Bertil discovered that there was a new light source – a fluorescent tube that produced a great amount of light at very low cost.”

and expanded more than 40 times, now boasting 55.000 m².

From the very first lamp, Bertil focused on meeting a human need and solving a problem. Using new materials and solutions, he had found a way to create added value for the user and profitability in his own production. An innovative approach that came to shape Fagerhult’s future activities and became a part of the company’s DNA.

In 1948, Bertil discovered that there was a new light source – a fluorescent tube that produced a great amount of light at very low cost. Certain that this was the light solution of the future,

70 years of lighting knowledge

he developed an entire collection of fluorescent-tube luminaires. A decade later, this paid off in Fagerhult’s first big prestigious order: 5.000 specially designed luminaires for the iconic functionalist National Tax Board building in Stockholm, “Skatteskrapan”. Fagerhult moved into the contract market, quickly becoming a key player in public interiors.

In the coming decades, the company grew steadily in the technical lighting field, although the focus remained on developing and manufacturing home lighting until well into the 1990s. By this time, Fagerhult’s signature traits of inquisitiveness and industriousness

had resulted in several innovations that changed the lives of millions of people.

The innovative plastic luminaire Fabian, of which more than 4 million were sold, and recessed downlights in the form of the popular Pleiad model, are just a few examples.

The courage to develop completely new luminaires based on relatively untested light sources is a shining trend throughout the years. When T5 fluorescent tubes were launched on the market, Fagerhult was one of the first companies to develop luminaires designed for the new light source.

“Delivering superior energy efficiency without compromising on glare reduction and visual comfort is our trademark.”

the T5 light source, electronic controls and effective reflector materials that revolutionised the lighting industry and set a new standard for energy efficiency.

When LED entered the scene 15 years later, the company followed the same path, generating as much light as possible, with no compromises.

The current head of development at Fagerhult, Leif Norrby, has been a part of the journey since 1978. He states that this uncompromising drive to offer the most benefit for users is still the defining characteristic of Fagerhult luminaires:

“Delivering superior energy efficiency without compromising on glare reduction and visual comfort is our trademark. Working closely with leading research institutes has given us an advantage in developing proactive solutions – lights that make people happier, more alert and more active.

Our sustainability concept doesn’t just cover energy conservation, environmental impact and working conditions; it embraces the entire human context.”

In 1969, Bertil – who had been the company’s CEO since 1949 – was invited to take over all shares in the company. This was the beginning of an international expansion that occurred both organically and through acquisitions. In the coming decade, Fagerhult established sales offices in Denmark, Norway, the Netherlands and Germany.

It also bought out its Swedish competi-

tor Ateljé Lyktan. In 1984, Bertil left the office of CEO.

A few years later, Fagerhult was acquired by the Swedish Almedahl Group. In 1993 it was time for the next acquisition, when the investment company Latour, under the leadership of the Douglas family, took over all shares in the corporate group. Latour gave Fagerhult another long-term and committed owner – and the Douglas family have remained a major owner even after Fagerhult’s introduction to the Stockholm Stock Exchange in 1997.

Not long after that, Fagerhult established offices in the UK and the group for the first time surpassed SEK 1 billion in sales.

The turn of the millennium kicked off a rapid expansion, and in 2005 Fagerhult opened its big production facility in Suzhou in China. Through several aggressive acquisitions, Fagerhult became one of the big names in the European lighting industry, not just in terms of technical development, but also in market share. Thanks to the Finnish company, Fagerhult began making inroads in the Russian market, alongside establishments and acquisitions in Central and Eastern Europe.

Among the biggest acquisitions were Whitecroft Lighting in the UK, Project Lighting in Ireland, Waco in Belgium and Eagle Lighting in Australia. Two other interesting acquisitions – LampGustaf in Sweden with its subsidiary Elenco

and LTS in Germany – came to be the cornerstones of Fagerhult’s extensive focus on shop lighting and outdoor lighting. The operations were divided into three business units with their own manufacturing and development: Fagerhult Professional, Fagerhult Retail and Fagerhult Outdoor.

In September 2006, Bertil Svensson received an honorary doctorate at Jönköping University for his “distinguished life’s work as a national pioneer, entrepreneur and leading businessman in the lighting industry… and for important support to education and research in the lighting field”. Through the “Bertil & Britt Svensson Foundation for Lighting Technology” he supported new Swedish education in lighting technology, which would form the basis of the Lighting Academy. Just a few months later, in November, Bertil left this world at the age of 86. That same year, the Fagerhult Group surpassed sales of SEK 2 billion.

In 2015, what had started out 70 years earlier as a three-man company with sales amounting to SEK 13.000 had become a world-wide company with 2400 employees and sales approaching SEK 4 billion. All thanks to Bertil, his mother Elisabeth and her needlework basket.

naires and everything’s ready to go. If you want to expand the system, you just add another room, and another and another … scalability is fierce!”

“Another strong argument for this solution is information safety. This kind of stand alone-system is not online, which makes it more difficult to hack. If attacking the system, it has to be done while physically inside the room, as it cannot be done over the Internet.”

auto-connect for all Human-centric lighting is a strong trend, giving users the opportunity to work in a lighting environment that supports alertness and wellbeing. e-Sense Tune is developed for any situation where the person “owns” the lighting and wants to adapt it to personal preferences and tasks.

As long as you have the device, the control is always at hand.

With the app for e-Sense Tune and a lighting system that includes the hard- and software required, you have a truly innovative lighting control in your hand, or in your pocket.

The graphical interface is designed for ordinary users and very easy to understand even if you don’t have a clue about what Kelvin is.

“e-Sense Tune is easily operated by each individual with a smartphone app.

We have created an intuitive interface that’s really simple to handle. Once you’ve made your settings, the lighting systems will automatically identify you and adapt to your personal preferences as soon as you enter the room. The system connects via the latest bluetooth standard – bluetooth low energy ‘BT SMART’ and we’ve also developed a unique solution to make sure no users outside the room can affect the system.”

The e-Sense Tune application has a function for each user to define two

different personal lighting scenes. It also incorporates daylight mimicking, where you can choose between two different settings inspired by nature. Both settings start with a lower intensity and a warm colour temperature. At lunchtime, the light peaks in intensity as well as in colour temperature, which until now has been getting cooler. During the afternoon, the intensity is once again lowered and the colour temperature gets a bit warmer. The difference between the two settings is that one is slightly cooler than the other, to match different personal daylight preferences.

“Of course, the application also has a setting for harvesting daylight, making

sure that the lighting system optimises energy consumption according to the amount of daylight outside.” in the occupancy cloud In the near future control systems like e-Sense Tune have great potential, says Daniel.

“From a hardware perspective, they have the possibility to harvest information on, for example occupancy or default settings, and pass it on. Though, this requires a gateway and proper settings.”

The evolution of retail We have not always shopped the way we do today and retail brands have not always looked the way they do right now. At Fagerhult we carefully monitor transformations to ensure we can deliver the best suitable and innovative lighting solutions when the retail landscape evolves. text katarina morén styf | photo istock photo, elin nilsson, örjan henriksoon

At Fagerhult we like to look forward, but let us take a moment of retrospection to reflect on how the retail landscape has evolved over time.

In-line with the industrial revolution that accelerated the economy a consumer society emerged. This urbanised social group, sharing a culture of consumption and changing fashion, were the catalyst the retail revolution.

Shops were starting to pop up and those in a privileged position could shop till they dropped. Purchases happened over the counter where personal meeting and relationships were key when getting loyal customers and sales.

what is in the future?

Looking forward a few decades you could say that such experiences and services are as important now as then.

Still the personal meeting, expertise and touch-and-feel possibilities are what differentiate retail brands from e-commerce. When bricks and mortar retail needs to create added value for the digital natives of the Generation I, they are transforming their brands into community hubs. These not only fuse commodities, education, cultures, art

and design – but also bring digital into a physical experience.

Do not be surprised if high-tech 3D body scanners appear, calculating your exact measurements. So no more jeans fitting agony – at least not because of size doubts. Also, keep checking your smartphone when shopping. We will be seeing increased personal messaging

and offers appearing on your phone when entering a certain shop or passing certain aisles of products.

the science of shopping

All retailers are interested in increasing sales, using advanced and detailed procedures in terms of marketing and displays techniques to influence purchase decisions and light is one of the key factors.

Research suggests that more than 65 percent of buying decisions are made in the physical store. All decisions are made consciously but the products and brands in a shop must pass our non-conscious filter to pop up as a viable choice. This amplifies the importance of the retailer to set the stage – since a lot of valuable decisions are made on site.

Jens Nordfält, PhD in store marketing, is dedicated to research and education at the Stockholm School of Economics and at the ICA, one of the Nordic region’s leading retail companies.

“We know that the store experience affects the consumer significantly.

Many customers allow themselves to be influenced of what to buy, but also what they should think about a product’s price and quality. In fact, it is impossible to consider a product without being influenced by the perceptual system.

And the perception is mainly affected by visual impression”, Jens explains.

There are many factors that affect the decisions made in a shop; the product assortment, the brand, the pricing, how the merchandise is positioned and displayed both in the shop and on the shelves. Research has shown that the shop atmosphere is central; defined by the colours, lighting, scent, sound, design, size and shape. Correlations

between feelings such as joy and excitement affect not only the time spent in the shop but also the share of purchases made. the impact of light As a large percentage of the purchase decisions are made in the shop, the atmosphere is an decisive factor as well as colours used. We believe that the lighting is an important element not only setting an atmosphere but also enhancing and signifying colours of the merchandise. Furthermore the light itself can enhance or generate colours by using Tunable White or RGB.

There are a couple of experiments that have tested the effects of lighting, which is often treated as only one of many elements in the store. To summarise, the research studies show that warm colours draw more attention but conversely cool colours are more appreciated.

These findings are something we at Fagerhult have incorporated in the way we plan light. We have examples where we have illuminated displays positioned next to the walls with blue LED strips casting blue light in the whole shop and using warmer light levels on the actual merchandise. Then we achieve a cool, encouraging atmosphere but also draw attention towards the products. This atmosphere can also be achieved with Tunable White that gives even greater flexibility for the retailer.

Light has been proven to significantly affect two human areas: vision and

sense of excitement. Lighting is necessary for us as customers to process the relevant information in the shop, but it can also enhance specific products where the retailer wants to boost sales. In that way, a well planned lighting solution can increase sales. The commercial impact of a lighting installation can also relate to how well it correlates with the brand values and the total shop experience. These values can be more difficult to measure in direct sales, but we know a good lighting solution can reinforce brand value and give the visitor a better experience, even if the actual purchase is later made on-line.

Lighting is an effective tool when you deliberately want to take the customer around the shop in a predetermined order, and a perfect way to complement and strengthen the effects of the layout of the store. light that sell We have done tests in shops where we displayed soft drinks bottles with narrow beams and a warm light to bring out the warm colours of the bottles. We compared this with the same display using only the general store lighting, which is very common in supermarkets today.

The customers paid more attention to the accentuated bottles and the sales of those increased. It all comes down to how our eyes and senses work. Our eyes and senses are always looking and searching for the brightest spot, that’s where the information is – no light, no information.

“A smart city should be created for the benefit of the citizens, to improve their quality of life.”

Søren Kvist, Project Manager at Copenhagen Solutions Lab, Copenhagen

Every city wants to be one – but what is it? Opinions on how a “smart city” should be are as many as the aspirants, though there is an end result which counts for them all. By using modern technologies knitted together, the smart city is a step towards a more sustainable society.

The development is driven by urbanisation. In Metropolitan areas the concept is a way to meet the pressures resulting from an increasing population.

The EU is an enthusiastic promoter of the movement and is running its own “Smart Cities Initiative” in order to accelerate the transformation of cities into fossil-free and low-resource communities. holistic approach Copenhagen is considered a frontrunner and was recently awarded the Smart Cities Award for its “Copenhagen Connecting”-project.

“It’s extremely important that you don’t embark on this kind of project for technology’s own sake. A smart city should be created for the benefit of the citizens, to improve their quality of life. For Copenhagen this is also an important step to realise our vision of a C02-neutral city in 2025”, says Søren Kvist, spokesperson and Project Manager at Copenhagen Solutions Lab, the City of Copenhagens incubator for smart city initiatives.

Copenhagen Solutions Lab works cross-departmental with the city’s administration, in partnership with local and international companies and

knowledge institutions. This task group provides a 360 sounding board to evoke and test new ideas, technologies and solutions to create a more liveable city in Copenhagen.

“The smart city cannot be seen solely as a matter for the community.

We need to interact with many different stakeholders: universities, business life and companies related to energy, water, gas, telecom, sanitation and so on…

The realisation of a smart city needs a holistic approach and we’ve found this is an easier way to communicate.” lighting as infrastructure And even if the potential is endless, the connected society has to be born according to a plan. Before heading off, experts were hired to identify possibilities and socio-economic effects.

Right now, Copenhagen Connecting is entering a new phase. A test area is built for evaluating different solutions and techniques.

“We’re not first to the ball, many of these technologies have been tried in other cities – but we need to make sure that they’ll work in our Nordic climate and environment”, says Søren Kvist.

An innovative twist is how Copenhagen is planning to use outdoor lighting as infrastructure for the smart initiative.

Street lighting is everywhere and every luminaire is connected with electricity, something that’s crucial to get all this tech stuff working. In the coming years 20 000 existing streetlights will also be changed into LEDs.

“Of course it’s a good thing for the

environment as they are very energy efficient. But it’s interesting how lighting is also turning into an infrastructure solution, as a vital part when building connectivity”, says Søren Kvist.

Every LED-module can be connected to the city’s IT-system where they can interact with each other. The lighting poles are also excellent for housing sensor equipment for water, wind and pollution as well as for traffic sensors.

“LED-luminaires also have an important advantage as they are always operating. They’re never totally switched off, only dimmed to extremely low levels. This means that other equipment will have power supply, regardless of the time of day.”

from traffic to flooding The ideas are flowing.

“Traffic is a core subject. For example, we can use the system to generate data for traffic lights, in order to create green waves for car drivers, cyclists and pedestrians. This means reduced pollution related to red light starts and stops and a safer traffic environment with less accidents. But it also saves valuable time for our citizens. Parking is crucial. If the system can be used to guide drivers directly to a free parking lot, it will save a lot of driving, irritation and CO2”, Søren Kvist explains.

“Sanitation is another area that we are looking into. With the help of ‘intelligent trashbins’ we can keep the city clean and plan our routes in a more efficient way. Recently we’ve had some problems with heavy rains and flooding and this system could provide us with

the information to guide our efforts”

Some of the ideas are already up and running as the municipality of Copenhagen is gifted with an enterprising traffic department. For instance, one has developed a ‘green wave’ application helping commercial traffic to avoid red lights. Copenhagen is known for its well-developed cycling infrastructure and some routes are paved with LEDs shifting between red and green light.

This helps the cyclists to keep the right speed and avoid unnecessary stops. a sharing society So, what can the lighting industry do to keep up the pace?

“Actually, I think the industry is doing a lot. After many years focusing solely on energy efficiency, producers have started to develop products adapted to network technology. I think

it is important to continue on this path, focusing on connectivity and Internet of Things. For us it is also vital that developers within the lighting industry choose to work with open technology”, says Søren Kvist.

Open technology means flexibility and the possibility to share information for the greater good.

“Our vision is to generate open data that can be shared with local entrepreneurs and companies with business ideas that contribute to the smart city and peoples wellbeing. Of course, we carefully consider integrity issues at all times and living in a big data era we have to design all smart city solutions with citizens privacy rights in mind”.

Lighting control – a look into the future So, it is finally happening. Lighting control systems are booming with new intuitive and user-friendly applications.

“Actually, lighting will form the core of our connected working environments”, says Daniel Unoson, Product and Application Manager at Fagerhult, looking into his crystal ball to see where we will end up next. text amelie bergman | photo mats andersson

You know the feeling: The growing frustration when trying to master the remote control in the conference room, while your customers are impatiently watching your every move. Or the defeat of calling the hotel front desk in the middle of the night on how to turn off the **** floor lamp that won’t respond to your feverish commands on the control panel. After decades of more or less intricate, non-user-friendly system solutions we’re finally up for a shift in paradigms. Lighting control systems have become more accessible and easier to install and use. At the same time, demand is growing really fast.

There are several different factors behind the development, says Daniel.

“As sustainability is an increasingly important issue in business, companies are searching for a way to minimise energy consumption. In this, lighting control systems are the natural approach. The new connectivity opens up for creative solutions and user-friendly interfaces enhancing the benefits.”

The Internet of Things phenomena is exponentially growing. Right now about 8 billion units are connected. In 2020 the figure is estimated to between 50–100 billion.

“No one really knows how much or how fast it will grow. But lighting plays a central part in this new Internet of Things infrastructure. As lighting is

present everywhere, in every building, it’s a natural connecting point.” connected lighting Using data from the lighting system is an interesting topic.

“The lighting system could connect with ventilation or communication systems in conference rooms. It could also be developed to integrate with the occupancy cloud giving the company information about occupancy, space efficiency and cleaning. The collected occupational data from the lighting control system can be of economic value.

Right now, we see a lot of different ideas developing on the market. For example, different providers of vending machines or cleaning services could be willing to pay for information on how to manage their activities in the best way. And as long as it doesn’t intrude on personal integrity – and the system is only logging activity, no personal data – it shouldn’t be a problem.” simplicity is key This also changes the traditional role of the lighting company.

“We’re not just a developer of innovative luminaires. Our knowledge in the field of lighting – what light is, the magic within and how it can be controlled for the greater good – is something that our customers expect us to share in our different control systems.”

“In order to make those solutions effective, we have to offer a wide range of systems covering the different needs of different organisations. From advanced, heavily programmed customised solutions with fixed router connections, to easy-installed plug & play solutions – and everything in between.”

It’s quite obvious that different ways of working needs different approaches to lighting – and that a renovation and refurbishment project will have other requirements than a new construction.

“The trend is obvious. Systems should be easy to install, program and use – simplicity is key. The possibility of continuous changes in the set-up is also important. I think that DALI will be the protocol used for controlling light also in the future, but the medium of transporting the signals, via wires or wireless, might be of another type.”

How about using the lighting system for Internet access? Wireless Internet through ‘LiFi’ seems to be one of the hottest topics right now?

“Hmm… I’ve tested LiFi and yes, it works. But it is still very limited, as you have to direct the phone’s camera at the luminaire at all times. If not, connection is disrupted. The way smartphones are designed today it makes it a bit hard to do the actual surfing. LiFi is an exciting technology but in situations where you have WiFi up and running, LiFi cannot compete. For the moment…”

New research takes Tunable White to the next level Blue light activates, warm light calms. Since the origin of life, daylight has set the rhythm for all beings. But do we all react the same to colour temperatures from different light sources? Researchers at Lund University have identified a correlation that will change the way we look at men and women. text amelie bergman | photo mats andersson, klas andersson, örjan henriksson, teddy strandqvist

Tommy Govén and Thorbjörn Laike Tommy is former Head of Lighting Technology & Research at Fagerhult, now retired but still active in research in Light and Lighting.

Professor Torbjörn Laike from the Department of Architecture and Built Environment, Lunds Technical University.

Natural light helps us to set our biological clock and affects our wellbeing. And artificial lighting can be used for the same purpose. The circadian rhythm can be stimulated with light, for example by using higher levels with cooler light until noon and then slowly return to lower levels and warm light in the afternoon.

Our preference for colour tempera­ ture isn’t static, sometimes we want a cold, activating light, others a warm relaxing one. Tunable White is a new technology permitting the user to alter the colour temperature to what we prefer, via the luminaire itself or the complete lighting system. This kind of dynamic lighting can have a profound impact on the personal wellbeing, alertness and productivity, and the evolution of LEDs has initiated new research within the area. the first in decades Tommy Govén and Thorbjörn Laike, researchers in Light and Lighting at Lund University, have previously conducted two studies to investigate how humans are affected by ambient light. This time, the research team has focused on which colour temperatures that people prefer

in a laboratory study when using LED lighting.

“A study of this type has only been made on fluorescent tubes. LED brings the question to the table once again”, says Tommy Govén.

How do people react to different colours – warm and cold light – and is there any difference between us? How do we perceive LED light at different level proportions between in the working area and the surroundings within the normal field of view? The study examines the preferred colour temperatures of participants aged 20 to 70 years. The evaluation is holistic and also includes luminance, glare and LED light flicker.

105 different light scenes During the sessions the subjects could select their preferred colour temperature at different occasions from 21 individually fixed light scenes, easily controlled from a tablet. The intensity of lighting in the working plane was fixed at one of the seven steps in a scale from 50 – 1000 lux and the relation between the working area and the surroundings was set to either 5: 1, 2: 1 or 1:1.

“For each scenario, the subjects could choose between colour temperatures from warm to cold, from 2700 K to 6500 K. This meant we programmed a total of 105 different variations.

Fagerhult has participated in the studies by contributing with development and programming of the different lighting scenes.” diffence between genders The results will be presented at the 28th CIE Session in Manchester, June 28th to July 4th and will most certainly get attention.

“Most noticeably we see a clear difference between women and men.

Women prefer a light that is slightly warmer, men prefer a light that is a bit colder”, reveals Tommy Govén.

“Of course, you cannot separate men and women to work in different rooms! But this knowledge can mean a lot when developing new lighting solutions with Tunable White in the future.

With increased knowledge about the user’s preferences it is possible to create more accurate solutions and probably to reduce the range in colour temperature in working areas.”

cundall, birmingham, united kingdom Cundall’s new 700 m2 office fit out project is a perfect hybrid of human-centric lighting and energy efficiency. The design concept focused on the needs of the staff and the activities they were undertaking, while paying consideration to the various exposures to daylight throughout the space. Intuitive and easy to understand controls played a central role, optimising the luminaires which included recessed Notor LED, Pleiad G3 and Avion. The net result was a workspace which, when operating at 100 % output, used only 6 W/m2 and in operation uses just under 4 W/m2. The project recently secured a CIBSE building performance award for lighting and a Lighting Design Award for Low Carbon Project of the Year.

Different colour temperatures change the impression of a displayed item and now you can switch items on display without changing the luminaires.

marathon tunable white Marathon Tuneable is a new interesting spotlight from Fagerhult. It is developed for the retail segment but works well for all type of areas that have the need for change in white colour temperature. Marathon Tunable enables you to change colour temperature with the same luminaire.

The colour temperature is ranging from 2700 K to 6500 K.

Different colour temperatures give different impressions, for example in jewellery shops gold jewellery are preferably illuminated with a warmer colour temperature and silver jewellery are on the other hand more desirable in a colder light.

munsterhuis sportscars, hengelo, the netherlands Munsterhuis Sportscars is a dealer of the prestigious brands Ferrari and Maserati. Because of a new corporate identity from Ferrari/Maserati, the showroom had to be redesigned.

The interior concept was created with a strong contemporary look back to the retro feeling. Therefore, we deliberately chose 3000 K as color temperature. A conscious choice is that each car has its own “light stage� through stretch ceilings that mark the position of the car.

To accentuate the architectural lines LED stripes are positioned as effectively as possible, so that all alcoves guarantee an outstanding interior experience. A linear power LED module (Notor LED) has been chosen for the stretch ceilings and walls. All accent spots are Zone Evo recessed with specifically selected 3000 K LED modules and reflectors.

What is the future of general lighting?

Everyone seems to agree that LED technology is the future of general lighting. Yet, there is already a debate in the market about what might come next. Annetta Kelso, Senior Marketing Manager LED Systems at Philips, and Leif Norrby, Product Development Director at Fagerhult, share their professional and personal views on an industry in transformation.

Who said that Lighting was a boring industry, where nothing ever happens? photo philips, marie peterson, รถrjan henriksson, fagerhult

what is the future of general lighting?

45

“What if the future is not so much about a new lighting technology, as about the way that light is used and the way we interact with it?”

Annetta Kelso, Senior Marketing Manager LED Systems at Philips

Annetta Kelso Annetta has worked for Philips Lighting in the UK and the Netherlands for over 27 years, in a variety of roles, including Product and Marketing management. For the last 15 years she has been active in the communication and market introductions of lamps, drivers and LED systems for European luminaire manufacturers. Other activities include managing the Philips Lighting Technology Training Program, speaking at Lighting conferences about the transforming lighting industry and writing many articles for the Lighting Trade press.

Annetta; what’s happening within the lighting industry right now?

“In the first 20 years of my career in lighting I used to have some difficulty in describing to my friends what I liked about the the lighting industry and why I remained there. And indeed, if you looked at it as a dispassionate outsider then it did not seem a very compelling industry to work in. All those dreary fluorescent tubes, ‘awful’ compact fluorescents and ghostly low pressure sodium lamps. Dreadfully slow, extremely conservative, traditional and dull. No-one envied me. But how different the situation is now. The coming of age of LED light sources for general lighting has shaken the whole industry to its core and dragged it in to the cyclical manufacturing patterns of the semi-conductors world. We have become an industry in the midst of a whirlwind of huge change. But also one that is quickly modernizing and reinventing itself, thereby appealing a lot more to today’s consumers and triggering wider interest.”

What has the impact been on the lighting industry?

“The psychology of a new technology moving in on a 120 year old established, slow and traditional market has been fascinating to observe.

I witnessed first-hand the emotions and struggles of the value chain, where huge mental change was taking place, provoking a whole cycle of reactions from denial, anger, scepticism and eventually acceptance. I faced shouting, angry lighting specifiers calling me a liar. I spoke to luminaire manufacturers, loudly denying the rapid advent of LEDs, yet proudly claiming 50 % of their turnover to be in LEDs a few years later.

The Lighting industry is maturing fast, but it is also an industry under severe stress. Lighting manufacturers today are heavily preoccupied with managing and mastering the mass penetration of LEDs, and its many new practical challenges and application learnings. There is hardly ever a dull moment.”

annetta about oled…

There is a lot of discussion and anticipation about OLED technology, which is attracting large R&D investments and gaining a strong foothold in the display panel market in mobile phones, laptop screens and televisions.

What place and role might this technology occupy in the lighting world in the future?

“OLED is a highly adaptive material that produces a very beautiful, soft, uniform light effect, without distressing glare. Yet compared to LED specifications and price points OLED technology is still some years behind. It would be wrong to see OLED as a competitor or the successor of LED lighting, superseding it in the future. It has always seemed quite obvious to me that OLED is a parallel technology, co-existing alongside LEDs, targeting very different applications with a distinct set of benefits. OLED technology is well suited to automotive lighting and also for ships and planes. It is also ideal for embedding in designer, artistic form factors, removing the boundaries of shape and size associated with conventional lighting. Its transparency, slim dimensions and bendable characteristics make it a very flexible light source, ideal for architectural and embedded applications, either in the home or semi-professional applications. Being able to integrate

light, make glass or mirrors glow, or create a sculptured, curved, diffuse pendant luminaire takes lighting to whole new levels that cannot be achieved with LEDs. It is a different playing field.” … and laser technology Another technology that is increasingly being mentioned when considering successors to LED is laser diodes?

“There is research emerging and there are early discussions taking place in the market. BMW has been developing laser based headlamps, which extend the visibility to 600 m, which has grabbed the imagination. Laser light appears to be a good light source for applications where the light needs to be transported or guided over long distances, from one central, remote light source. Very similar to fibre optics which I’m familiar with from my previous experience as a Product manager.

Laser technology is also being trialed in projector and beamer applications, but not yet in general lighting.

From the various sources I have come across on lasers and laser diodes, it seems that there are some quite technical challenges still to be overcome as well, in the areas of efficiency, thermal

stability, colour rendering, uniformity of beam and safety.” no turning back How do you see the future of lighting?

“Nowdays it is unthinkable that we would ever turn back the clock towards the old conventional light sources. It seems to me that LED technology is perfectly capable of providing efficient, high quality, white light, and will build up a formidable pedigree in the foreseeable future.

And yet there are already those who are looking ahead and voices speaking out at conferences, debating what might come next. It is an interesting question; are there further major technological changes, imminent or already apparent on the horizon?” linked to emotions Apart from light itself, Annetta continues, “I would look at the future of lighting from another perspective. What if the future is not so much about a new lighting technology, as about the way that light is used and the way we interact with it? What if lighting was to fit into to a larger eco-system and become valuable to end users for other reasons

OLED’s transparency, slim dimensions and bendable characteristics make it a very flexible light source, ideal for architectural and embedded applications.

than just providing illumination?”

You are talking about connected lighting?

“Yes, connected lighting is at the centre of all lighting discussions and speculations right now. And, unlike OLEDs and human centric lighting which are familiar terrain, connected lighting is still relatively unknown, undefined and more intangible. Yet it has the power to throw our current lighting world upside down (again) and change the way we experience and interact with light. Lighting is already joining the ‘Internet of Things’ in the consumer world. Connected light bulbs, such as the Philips Hue system, allow you to control the colours, ambience and intensity of the lights in your home, via your smart phone, when and where you want, at work, or on holiday. But they can also go beyond mere illumination. Via apps the lamps can alert you to other significant events touching your life; football clubs scoring goals, stock prices rising, your husband about to arrive home (!). These are fun and exciting things that brighten up your everyday life. This is lighting linked to emotions.”

47

professional lighting connected But would this fun element translate to the hard, rational professional lighting market?

“Not likely! Any form of connected lighting in the professional world will have to be based on rational argumentation and the promise of money saving, or money generating activities. It will be about lighting, as a carrier for providing information about the way people are using a building, moving through a street, or shopping mall.

Think of intelligent luminaires receiving signals and instructions, sending data and interacting with other systems and databases. It will be about managing lighting assets in a city, simplifying maintenance, gathering data to allow for manufacturers to offer service contracts.” this happens now Why should we be so sure that this will happen, and why now?

“All the market signals are now pointing to viable business cases. The cost per lighting fixture to be connected is predicted to be lower than ever, taking in to account reduced installation time due to quicker, simplified wiring and less commissioning issues.

The omnipresent, extensive infrastructure of lighting will make it an ideal carrier for connectivity in the professional and commercial world. We should think in terms of value creation through

the ‘real estate’ of lighting opportunity.

The value of big data collection and analysis on the behaviour of people is recognised as a business opportunity by companies for more direct targeting of customers. And Lighting is everywhere where people are and is therefore an ideal platform to capture and monitor human centric data.

In the ‘Connected Office’ intelligent lighting systems will not only provide light in a cost effective, efficient manner, but will also interact, via IT systems, with HVAC, blinds and security systems to offer even more savings and flexibility. Knowing how a building is used offers potential for reducing square meters per employee and therefore money savings.

Similarly in Retail, targeted customer interaction can be greatly enhanced by knowing a person’s exact location in a store at a particular moment. All these connected lighting services will require software support, maintenance and consultancy support, an excellent opportunity for services and value added selling.” connected lighting affect products How do you think connectivity will affect product development?

“Connected lighting technology will enable multiple application possibilities and the challenge will be to define the winning propositions and their real benefits. The diversity and complexity

of options and products will certainly increase. I think we will see a rise in intelligent luminaires, equipped with smart hardware and software components, in the shape of LED Light engines, lamps, radios and sensors.

Future proof, forwards and backwards compatibility should be key criteria here to facilitate easy upgrades for future applications and solutions unknown today. System solutions should be robust, reliable and intuitive and easy to use. They will also need to address privacy, safety, reliability and system and data security”. changed value chain What other changes do you foresee to make this happen?

“None of this can be achieved by just maintaining the existing value chains and infrastructures. For lighting to be able to talk to different systems in a building or city, and link in to big data collection points, you need new parties such as IT companies, system integrators and software designers to become part of the new eco system.

So with the Lighting and IT industries set to entwine, new partnerships will arise around the current value chain, focusing on serving the professional end user. Lighting companies will have to learn the language of system integrators, IT networks and software providers. The end user will be increasingly advised by a new breed

what is the future of general lighting?

of specifiers, with new forms of lighting tenders and products specifications.”

So there are plenty of changes and innovation still to look forward to then?

“There are still many steps to take along the road to connected lighting systems and many unanswered questions.

Much will change and this will not be an easy transition for lighting manufacturers. But with all the boundary conditions in place, the rewards could be substantial, as a whole new vista of value added service opportunities will open up. We live in exciting lighting times!”

Leif Norrby Leif is Fagerhult’s Product Development Director, celebrating 37 years within the business – and with the company. During his career Leif has lived the revolutions of the compact fluorescent lights, T5 and LED.

from the fagerhult perspective The lighting industry is in the middle of a paradigm shift, experiencing some radical changes. What’s happening Leif?

“We are experiencing the LED-fairy tale, for real. After years of discussions, preparations and product development, the technology is mature for commercial success. The market is booming right now. New products find their way to the market immediately, and the surge is intense. Five years back, the major part of our sales were products older than three years, novelties needed quite a long time to establish themselves on the market. Today, new products are driving the whole deal. In February 2015, LED counted for 60 percent of our monthly turnover. That pretty much says it all.”

What are the challenges in your perspective at Fagerhult?

“Actually, lighting has changed into another industry. Traditionally, lighting was a manufacturing industry focusing on mechanics and light sources. Today, we work with semiconductors, which basically means that we’re part of the electronics industry. This brings new demands on competence and skills development, both right now and in the future.

As there’s a new, more energy and cost efficient LED-version presented every eight month, we also need to have the strength and capacity to upgrade the existing LED range at regular intervals.

Not to forget; innovative product development has to be up and running at all times.” fagerhult and connectivity What about connectivity? Is Fagerhult taking any actions within the field?

what is the future of general lighting?

“In the story of connectivity, lighting has the opportunity to play a leading role, as it offers an already existing infrastructure – indoors as well as outdoors.

This infrastructure serves as a central part of the Internet of Things. Though, in my opinion, I think we should be aware that we’re only at the beginning of a long journey. There are many communicating devices to be linked together and it is a complicated process.

At Fagerhult, we see great opportunities and are following development very closely. It is reasonable to believe that lighting will be an asset when collecting data for the cloud, for example data on occupancy and efficiency. Information can be used for strategic decisions concerning facility management and organisational development. From being a provider of lighting solutions, I think lighting companies in the future will also have the role of consultants.” led is here to stay So, what happens now?

“From Fagerhult’s perspective, LED is the obvious technology for the foreseeable future. OLED is clearly interesting, but considering efficiency and cost aspects, I see OLED mainly as an alternative for architectural or creative solutions just as Annetta says.

For professional lighting, LED is the most commercially viable option. And of course, LED will be further developed for new exciting applications. For example, I believe LED will be part of several integrated solutions – in wall modules or different types of store interior.

In times of technical breakthrough and progression, I would also like to add something about the importance of visual comfort – very Fagerhult, I know…!”

Leif says with a smile.

He continues; “But we must not forget about visual comfort. LED light is incredibly intense and therefore it is more important than ever that we take into account the lighting environment. Glare and colour stability over time cannot be overlooked. Let’s not throw 70 years of acquired knowledge out the window. It might be a brave new world, but technology should always serve people.”

innovations for better light

51

Innovations for better light Over the last 70 years within the lighting industry various new findings have come our way and we have embraced the change. When we started 1945 there was the light bulb but as the years have passed, new light sources and technologies have emerged, like the LED revolution of last couple of years. text klas andersson | photo fagerhult

For each new development we have increased our understanding of light, providing the stimulus for new solutions which deliver good, energy efficient, lighting for humans. A lot of the new findings have forced us to learn and rethink what we knew during the years. compact fluorescent lamp In mid-eighties there was a new light source on the market, the compact fluorescent lamp. Suddenly we were able to make energy efficient lighting with smaller dimensions such as downlights and wall luminaires. It was an intensive light source and there was a lot of light that had to be taken care of. This little light source could have a luminance (light intensity) up to 40.000 cd/m2!

Basically we had the energy efficiency of a fluorescent tube in a miniature size.

The new light source suddenly became an alternative to the traditional bulb in a lot of applications and led to a whole new range of stylish fittings. reflector technology In the very first Pleiad downlighter that was released in mid-nineties we developed a symmetrical light distribution

from a horizontally positioned lamp.

Why horizontally? We simply wanted to keep the recess depth as low as possible since there often is a lack of space above the suspended ceiling. With a lot of engineering skills we designed a reflector with symmetrical light distribution with excellent cut-off from the horizontally positioned lamp! When others made cut-outs in the reflector for lamp switch we made a toggle solution for that in order to get the most light out of the Pleiad.

the market in the mid-nineties, making many of the norms of T8 luminaires irrelevant. One aspect was that the T5 tube performed at the best at an ambient temperature of 35 °C instead of T8’s 25 °C. Next thing was to decide what we should do with all light and how we should control it? The luminance in cd/ m2 values rose about 50 per cent and compared to the T8 there where issues with glare from the new, highly intense light source.

The answer was to design totally new double parabolic louvres that were not only glare-free but also provided higher efficiency to the luminaire. The solution consisted of side and cross reflectors where the cross blades were designed with a sealed top that reflected the light back into the side and top reflectors which minimised the light losses. The curved tops of the cross blades eliminated unwanted reflections on the side reflectors and gave a good mechanical cut off in all directions.

electronic ballasts In the early nineties we also got the electronic, high frequency ballasts resulting in increased energy efficiency and a flicker-free light! At Fagerhult our big issue was controlling the heat on the ballast since heat kills electronic devices.

After some years we introduced our own policy regarding thermal control and stated that we should always have at least a 5 °C margin to the stated TC-point on electronics. the t5 led to r5-louvre Another good example of innovation is when the T5 fluorescent lamp entered

Loop Light is one of Fagerhults best selling T5-products with more than 300.000 sold over the years.

To maximise the light output out of the luminaire we also made the cross blades thinner and that itself made the light opening’s area approximately 4 percent larger, resulting in higher efficiency. led LED revolutionised the lighting landscape; high light flows ensured superb efficiency and economy, with a lifespan of tens of thousands of hours.

From what was previously the domain of decorative accent lighting, LED technology evolved into a practical, general lighting option. To truly embrace the benefits of LED, and to address the demands it posed in issues of glare and heat management, required completely

new solutions, rather than just changing the light source. The great challenge with LEDs is to keep glare within reasonable levels. It is not unusual that diodes and LED modules have a luminance (light intensity) of over 300.000 cd/m². In contrast, a standard T5 fluorescent tube has a luminance of 17.000 cd/m².

Again, we started from scratch, developing new luminaires specifically for LED, creating viable solutions across the whole spectrum of a lighting project.

LED’s greatest advantage is also its greatest challenge. Balancing efficiency with ergonomics. Combining good economy and lighting comfort. With our experience, lighting know-how and innovation we did just that .

Breakthrough in gerontology?

“Dynamic, ambient light improves the wellbeing and health for elderly” What if lighting could help the elderly to a happier and healthier life?

Actually, it can! A new research project at Lund University indicates that dynamic, ambient light is a good recipe for golden oldies. text amelie bergman | photo teddy strandqvist, istock photos

We live longer. As the average life expectancy increases, we are also increasing our expectations for a long and happy life. Retirement is postponed and people often choose to work into their 70’s.

Consequently, there are many reasons to do research in the gerontological field.

“Current and future retirees want to live an active life and want to remain living in their home environment as long as possible. It is also becoming more common to be cared for in one’s own home”, says Tommy Govén, researcher in Light and Lighting, who conducted the study with Prof. Thorbjörn Laike at Lund University.

The research duo specialise in investigating how people are affected by increased ambient light, with their previous work focusing on students in primary and secondary schools. Now, they are looking into the situations of the elderly. The study is yet not complete and will be presented at the 28th

CIE Session in Manchester, June 28th to July 4th. customised led-lighting The aim was to explore whether dynamic ambient lighting may have a positive impact on the alertness, wellbeing and health of the elderly. The study was conducted in a nursing home with participants over the age of 80. A specially designed LED-luminaire for increased, glare-free, ambient lighting was designed and installed in the different rooms of the nursing home – the resident’s bedroom, the day room and the dining room. Fagerhult contributed in the development of the luminaire and has also been involved in developing control- and measurement equipment as well programming of the different lighting scenes.

The study was conducted over one year, investigating the resident’s feelings regarding light experience, wellbeing, alertness and sleep during the four

seasons. Other parameters considered were nutrition and medication as well as energy consumption. supports circadian rhythm Every one of us is affected by the seasons and the availability and absence of light. When getting older, the circadian rhythm is disturbed by various reasons.

“The lens of the ageing eye leads less light to the retina and elderly who have difficulties moving may not have the opportunity to take advantage of the daylight outdoors. This may disturb

the circadian rhythm, leading to sleep disorders. Our hope is that the dynamic ambient light can make a difference”, explains Tommy Govén.

Although no results yet been presented, it looks very promising, he reveals:

“The test persons’ subjective experience is that they felt less drowsy and more alert during the days, even in the dark season. The quality of sleep was also better for the experimental group; they tended to wake up less during the night. We have also noted fewer injuries

due to falls during the test period. An interesting turn is that all subjects have asked to maintain their new lighting…”

If the presented results meet expectations, this knowledge may contribute to a new way of lighting the living environments of the elderly.

“For the individual it means improved quality of life and health. For society, there are possibilities to major savings from less institutionalisation and lower costs for medication or treatment of injuries.”

It’s time to enjoy our otium.

e-Sense Organic inspired by nature Where to turn for an intuitive and extremely energy efficient lighting solution that needs no programming whatsoever? Ask nature! e-Sense Organic is an innovative lighting control system inspired by natures intelligent communication. text amelie bergman | photo fagerhult, istock photo

e-Sense Organic offers plug & play lighting control in i.e. open plan offices.

e-Sense Organic can be compared to a school of fish, where every individual continuously makes small decisions in response to its neighbours and environment. Each fish operates independently – yet it is part of a flexible system using distributed intelligence to solve complex problems easily, without central control. e-Sense Organic is a system that applies nature’s algorithms in a similar way.

“This plug & play system is the perfect choice in situations where you want to achieve optimal energy savings without complicated installations or any programming at all. It’s very cost effective to install: you just put up the luminaires and that’s it”, explains Daniel Unoson, Product and Application Manager at Fagerhult.

like a conversation Each luminaire is equipped with a communicating IR tranceiver. The moment a sensor node detects occupancy, the luminaire responds with a predetermined light level. Simultaneously, it communicates with the luminaries in its immediate surroundings, telling that there is something happening.

The near-by luminaires react by lighting up on a slightly lower level, and continue to send the message forward.

This way, the luminaires creates an “occupancy cloud”, sharing information and responding to it as individual fixtures. The premises are always lit to facilitate work and make people feel secure.

“It’s almost like the luminaires are having a conversation. ‘I saw someone

and lit up a 100 percent, I’d like you to turn your light on, but 80 percent is enough… I’ve heard there’s people around and 10 have lit up to 80 percent and I think you should as well, up to 30 percent…’ and so the dialogue goes on”, Daniel explains. independent of changes Naturally, e-Sense Organic is equipped with daylight harvesting as well as presence detection features. As it is built on infrared communication, the system won’t be affected by layout changes.

Walls and function can be changed without any engagement with the lighting.

“It is flexibility in a nutshell.”

Fabulous Fabian – an icon reincarnated When you turn 70 a birthday cake alone isn’t enough. We’re celebrating by taking up the production of a true Fagerhult icon! Fabian is a subtle retro fixture, deeply connected with our innovative heritage. text amelie bergman | photo örjan henriksson, mats andersson, cecilia selvén

When launched in 1969 Fabian was Sweden’s – maybe even the worlds – ever first fitting made of plastic. It was a huge success and sold over 4 million copies.

According to the birth certificate, Håkan Fransson is Fabian’s proud father.

At the time of inception Håkan Fransson worked as an in house designer at Fagerhult. With a safe hand and fluent lines he imprinted Fagerhult’s visual expression during the late sixties.

“I’ve always have had a soft spot for curved, chubby lines”, Håkan admits, while walking down memory lane.

“But I really do think that Fabian’s wild success was a spot-on combination of innovative material and design complimented by a very affordable price.

Hey, it only took 11 seconds in assembly – that’s lean production!” innovation at its best Young Fabian had been endowed with a range of fantastic properties, donated by his three fairy godfathers – former development manager Bernt-Olof Berntsson, engineer Jörgen Johansson and the late Elis Svensson, head of Fagerhult’s prototype workshop.

“At the time, Fagerhult was still a large supplier of domestic lighting and the marketing department called for a new wall mounted bedside luminaire with a competitive price tag”, as Jörgen Johansson – still a member of Fagerhult’s development team – recalls.

“Actually, our aim was to force the price all the way to the basement, and in order to do this we had to reinvent ourselves. Our eyes turned towards polypropylene that was quite new to the lighting industry.”

“No one really knew what it was really capable of. But as it turned out”,

“We are planning to sell 10.000 units of this fantastic luminaire. Just go ahead!”

Engineer Jörgen Johansson and former development manager Bernt-Olof Berntsson.

Bernt-Olof Berntsson continues, “we had a local supplier of this brand new material.”

The supplier’s main products were thermoses with a housing of injection-moulded plastics that came in two different sizes. The housings could easily withstand the warmth from the hot beverages– but could it take the heat from a bulb? Trial and error was the only way forward.

“We slaughtered two thermoses, one of each size, and from the two hous-

ings Elis created the first prototype”, Bernt-Olof remembers.

Several prototypes later the development team had created a seamless, screwless design that could easily be implemented in the production system.

Due to the absence of screws, assembly could easy be done with the help of a special fixture. The procedure was clocked at 11 seconds flat.

Still, Fabian required heavy investments.

“I specifically remember one

meeting when the supplier pointed out that this would require some new, expensive injection tools. But Bertil Svensson, Fagerhult’s founder and managing director, was in good spirits.

‘We are planning to sell 10 000 units of this fantastic luminaire. Just go ahead!’, he said encouraging. No one could have guessed that Fabian actually would sell 4 million copies!”, Jörgen Johansson laughs.

placed an initial order for 5.000. The introduction price was set to 19.95 SEK, equivalent to 18.80 € today.

Fabian was cleverly marketed as an all-round luminaire that did not just belong in the bedroom, but in the living room and the study too. “You’ll need at least five Fabian at home!”, the ads stated. The fact that Fabian was offered in a wide range of colours following the latest interior design trends contributed to its persistent success.

Soon, Fagerhult became known as the frontrunner within plastics. This resulted in several iconic luminaires as Cobra and Lucifer, the later designed by the “it” team in plastics – A & E Design,

It has also been the subject of a slight face lift and is now produced as a pendant; the proportions are a little bigger and the plastic housing has been replaced by sheet metal or opaque glass.

The opaque shade has a contemporary twist sympathetic to the most varied of interiors. And there’s still one Fabian for

every room. Let it add some extra sparkle over café tables, desks and counters, in windows, bars and hotels.

The new Fabian has the same colourful spirit as the old one as the sheet metal housing can be coated in any shade you fancy.

“There are 26 standard colours to choose from. We also offer an exclusive version in opaque glass”, says product manager Peter Björkman who has made sure that Fabian is just as up to date now, as it was then.

“Fabian comes with a super-efficient and dimmable, long life, high quality LED-module. It is truly a child of its time!”

“This shop should feel like home but also reflect our history”, says Linnea Blank, Concept Designer at Hästens.

Hästens has a long history in manufacturing beds, 160 years in fact. It started back in 1852 in the small town of Köping in Sweden. Today distributors in 40 countries around the world represent this well-known brand. winner of sustainability award Sustainability and local production is important for Hästens. These are a few of the reasons why they choose Fagerhult as a lighting partner to provide a creative and ultra-energy efficient lighting solution. The Lighting designer and the Light Agency at Fagerhult Retail established a creative collaboration with the concept department at Hästens.

Together they found the right lighting solution for the new flagship shop at Birger Jarlsgatan in Stockholm, a process which resulted in the lighting became a part of their new shop concept.

With only about 4,7 W/m2 this Hästens shop became one of a kind. To the extent that their flagship shop was the first retail store to win Fagerhult’s 2014 Crystal Clear Award. Highlighting the importance of working with an ecologi­cal mind-set, the Crystal Clear Awards are a part of Fagerhult’s environmental initiative of the same name, recognising innovative sustainable thinking in the world of retail lighting.

The solution, with the innovative use of mini spotlights in the sleep spa on the lower floor, is the result of a very creative lighting design.

The use of controls shows a very forward thinking attitude and provides a platform for yet further developments in the future. Not solely in regards to saving energy but also to create an atmosphere that attract customers and really captures their ethos, which is an investment in their brand as well as the commercial store. lighting enhances the concept Lighting is an essential element of a shop’s interior design.

This is something Hästens put in a lot of effort in establishing and they have used lighting to create dynamics and harmony at the shop’s different areas. welcoming atmosphere The entrance floor is bright and has a welcoming feeling. The lighting solution is created to lead the customers into the shop. There are a few exclusive beds for display and areas for discussion and relaxation. Track mounted Zone Evo LED spotlights gives a comfortable light and its design is well suited to the interior.

The spotlights create a luxuriate feeling that defines the room, equipped with cap cone accessories to reduce the glare.

The display wall, with a variety of merchandise defined by the characteristic Hästens square pattern, is illuminated by Diva II, which provides discreet integrated lighting.

Being situated in a popular shopping area in Stockholm places a large emphasis on the instant appeal of the store window. The lighting enhances the window space and there is a special

night lighting scene installed to intrigue the visitors after trading hours.

The lighting solution for the stairs, leading to the bottom floor, is created to increase curiosity to enter the basement, so that the area is not mistaken for personnel or warehouse stairs. sleep spa When you take the stairs one level down you enter a dark and cosy environment, a “sleep spa” where visitors can try out the different beds. The lower level is designed to increase relaxation and an intimate feeling for customers to explore their different options- reflected by their approach to the lighting.

The low ceiling height of the basement floor lends itself to a solution with Fagerhult’s LED mini-spotlight, Relay.

Relay spot has a track with three spotlight heads. These units create just the right cosy and intimate feeling Hästens were looking for. The Relay spotlights consume only 6–7 W compared to that of a regular one with 17 W. With this lighting solution Fagerhult were able to keep the consumption down to an

“Using that kind of narrow beam spotlights with such low output was not an obvious decision. It meant taking a chance, to try something new. We tested it thoroughly before installing it”, says Paul Esplana, Lighting Designer at Fagerhult.

During this process Fagerhult identified the possibility to enhance the product with specially developed cap cones to further reduce the glare.
