Big business opportunities with super fast connectivity and talkative lighting Lighting is in an incredibly exciting phase – and has been for some years – with the availability of affordable, bright and long-lasting white light LEDs for general lighting. This is still the case as the LED revolution gathers pace further. Yet for those major lighting manufacturers that invested massively in the LED developments, which have led to this revolution, the future is perhaps not so bright. This is because of the commoditisation of LEDs, with ever-larger numbers of firms throughout the world now making low cost LEDs at the expense of those companies that developed them to the advanced and successful stage they are at now. Philips, Megaman and OSRAM are two such key companies. Yet the latest developments, not just in lighting – though these are still occurring – but also in the Internet of Things (IoT) and the latest wireless transmission methods (such as Li-Fi), will revolutionise lighting still further. And this can benefit both key lighting companies and electrical contractors and installers – not to mention end-users. Connected lighting that talks to a wide range of other devices and controlled via your smart phone and the Internet is one such development that will (and is already) revolutionising the smart home and building automation generally. Yes, yes….we know that some connected devices seem more than a bit silly – witness the Brighton man (apparently a data specialist) who tried to commission the ‘smart’ kettle from hell. It took him a full 11 hours to successfully setup his new Wi-Fi enabled kettle to produce its first cuppa! He’s now a Twitter sensation! Why anybody would want to operate their kettle from a smart phone is beyond us, but that’s not really the point. The point is that LEDs, organic LEDs (OLEDs), Internet-enabled lamps, the IoT, smart devices generally plus super fast Li-Fi wireless connectivity are together changing our world. Better get used to it. Better still, learn to use these technologies and make lots of extra money from your businesses… ….which is why this issue of Smart Electrician concentrates upon these very topics.

Smart homes and cybersecurity, what are homeowners’ concerns?
ABB’s modern lighting solutions ensure optimal illumination for all buildings and all occasions at the highest energy efficiency possible.
Is there a role for tidal energy and how many jobs could be created for the electrical sector? These are important questions answered here.
The successors to LEDs are already on the way - OLEDs. However the technology behind it promises to improve LEDs and some of its inherent problems too.

Our question is simple, and it's one we want everyone within the electrical value chain from home owners to suppliers to ask:
Does it Comply? (to the UK Electrical Industry Standards)
Asking this question each time you do business eliminates the risk that you could inadvertently purchasing or installing a non-compliant product. The trade in non-compliant and counterfeit products is not a victimless crime; it hurts the electrical industry as a whole and diminishes the trust and reputation of people and companies that are doing the right thing. If you would like to find out more about this campaign, visit us at www.doesitcomply.co.uk
Does It Comply? is an industry initiative lead by ACI, BEAMA, LIA, ESCO and GAMBICA and supported by Voltimum. The mission is to educate and inform contractors, installers and specifiers to the damaging consequences to the industry from the trade in non-compliant products, whilst raising the profile to the wider stakeholders of issues with such non-compliant products.

The force
OLEDs The force within OLEDS within
When it comes to the future of high-definition image display, it is impossible not to mention the OLED light technology, which will change the lighting industry. Very soon the difference between LED and OLED technologies will be something of the past, with OLEDs taking their place at the podium.

Smart Electrician
ISSUE 04 | 2016
OLED is an acronym for Organic Light-Emitting Diode – it is basically an LED which uses organic compounds to improve its own lighting and contrast ability. When applied in creating displays for electronic equipment, it is capable of generating images with more clarity and brightness than plasma or liquid crystal display (LCD). But it gets better; OLEDs consume even less energy than these technologies, making them more efficient, as well as simpler to make, much thinner and without any of the environmentally damaging metals of the current technologies. How it works OLEDs follow the same principle of the siliconbased inorganic LEDs but instead of using layers of n-type and p-type semiconductors, they use organic molecules to produce their electrons and holes. An OLED consists of multiple layers - six different layers, to be precise. Its active layers have an overall thickness of less than 500 nanometers (that’s 100 times thinner than a human hair). On the top and bottom there are layers of protective glass or plastic. The top layer is called the seal and the bottom layer the substrate. In between those layers, there is a negative terminal (cathode) and a positive terminal (anode). Finally, in between the anode and cathode are two layers made of organic molecules called the emissive layer (where the light is produced, which is next to the cathode) and the conductive layer (next to the anode). The technology, which is already of key importance to TV, computer monitor and laptop manufacturers, is particularly significant because it works without a backlight or filters. OLED can display deep black levels and can be thinner and lighter than LCD. In low ambient light conditions (such as a dark room), an OLED screen can achieve a higher contrast ratio than an LCD, regardless of whether the LCD uses cold cathode fluorescent lamps or an LED backlight. OLEDs are about to change the design/architectural lighting world too. What are the differences between OLEDs and LEDs? OLEDs are surface lights, LEDs are point light sources. However most important is that both technologies are designed for different areas of application. OLEDs emit
a soft, diffuse light and are primarily suitable for decorative, atmospheric applications. Furthermore, they have potential for flexibility - in the long term it will be possible to turn them into all kinds of objects, thus turning all kinds of objects into all kinds of lamps. The efficiency of mass production OLEDs is currently about 25 lm/W, making them more efficient than either incandescent bulbs or conventional halogen lamps. However OLEDs cannot reach the efficiency of fluorescent lamps or LEDs. Research is ongoing to improve the efficiency, and OLEDs have already been enhanced to 87 lm/W, nearing the level of fluorescent lamps. OLEDs are a two-dimensional light source which provide light without aggressive glare or/and shadows. You can look directly at OLED light sources without glare - in stark contrast to conventional light sources such as incandescent lamps, halogen lamps and LEDs. Because its layers measure less than 500 nm, OLEDs are extremely thin, consequently making them extremely flat, lightweight and flexible. The lighting system may therefore be ultra discreet, transparent and mechanically flexible and can cover a large area. However, there are still plenty of limitations to take into account alongside the product flexibility and flat design properties. But with its diffused light, OLEDs are suitable to cover large areas. The result is a new type of flat light source very different from any previous source of light. OLEDs can even be printed onto any cheap substrate using an inkjet printer or even by screen printing - offering an unlimited range of product opportunities. For example, OLEDs can be manufactured from thin ►

and flexible materials such as plastics or even roll-up displays embedded in fabrics or clothing. This allows the creation of ‘light leaves’, flat panels which could be glued to ceiling like wallpaper, illuminating the entire environment. OLEDs’ new design lighting revolution OLEDs are more than just light sources, they are design elements. When off, they have a very different look from conventional light sources. They are very thin, very flat, very light and therefore very attractive. And depending on the top layer and substrate material, they can also be transparent, diffuse or mirrored to offer an entirely new design. Once they become more widely used, luminaire designers can enjoy enormous freedom provided by this technology. OLEDs will open the door to new applications such as light bricks, light partitions or sources of transparent light that only emit light at night and but serve as a windows during the day. OLEDs
market will develop in parallel with the OLED design and construction markets. OLEDs, and OLED-based devices are, currently, considerably more expensive than conventional lights or LCD devices and therefore are primarily suitable for the high-quality sector. And for a while longer, OLEDs lighting design installations will only be affordable to high–end hotels and restaurants. But this will soon change as research and product development increases. OLEDs will generate completely new application areas and expanding markets. They are already inspiring designers and will enrich the fixtures market for high-end designers in the near future. Longer term, we hope they will assist revolutionary changes to the entire lighting market. LEDs were poised to take over the lighting universe, and in a way they did but LEDs are slowly losing their edge. However OLED technology is catching up. Very soon the

Optimised lighting systems achieve energy savings while ensuring comfort
Optimised lighting systems
achieve energy savings while ensuring comfort
ABB’s modern lighting solutions ensure optimal illumination for all buildings and all occasions at the highest energy efficiency possible. With ABB-free@home in the residential market and ABB i-bus KNX for the more commercial or multi-dwelling projects, ABB has a solution that helps to reduce the use of energy. Often in an open plan office, lights are switched on fully whether the workstation is occupied or not. And in case it is, lights are still operated at 100% regardless of the ambient light being present. ABB helps to ensure identification of these areas and scenarios, controlling the lighting in a way so energy is only used as much as actually needed and where it’s needed. This way we can reduce the energy consumption up to 60% but at the same time maximising the comfort with only minimal user interaction, if any at all. Every room will be set at the ‘right light’ with user friendly program settings, enhancing the environment, too. In this way, it can be controlled centrally – from basic regulation to full automation. Energy management included.

The UK’s electricity-generating capacity needs to turn away from fossil fuels to zero carbon sources. Is there a role for tidal energy and how many jobs could be created for the electrical sector? By 2030 the UK will have closed 82% of its existing fossil fuel based power station capacity. At the same time, electrification policy calls for more electric trains, more electric heat pumps and more electric cars. The result is net new demand and dwindling supply. ►

The ECA submission went on to emphasise that tidal power could ‘help the UK to face the considerable challenge of maintaining UK energy capacity and security, while meeting carbon reduction targets.’ ECA director of business Paul Reeve commented: “To help Britain to keep the lights - and everything else - on, the UK desperately needs investment in predictable renewable energy capacity.

hours a day. The lagoons will operate a system similar to a lock gate to alter the water level either side of a sea wall. When the tide starts to rise, gates in the wall are closed and water builds up outside the lagoon. When the tide is full outside the lagoon, the gates are opened and water rushes past the turbines to fill up the lagoon. When the tide turns to go out, the gates are shut to hold the water inside the lagoon. As low tide is reached outside the wall, the gates are opened to generate power again as water flows through from the raised water level in the lagoon.

KNX; revolutionary, reliable… available Iain Gordon, KNX UK President and Managing Director of Hampshire-based contracting firm, GES Digital, discusses how the vast range of products within the KNX control eco-system can make life easier for the smart-thinking electrical contractor.
With a substantial increase in the amount of consumer facing smart home gadgets, it can be difficult to know where to start. It’s possible that brand loyalty will steer home owners to request, and installers to specify, products from well-known technology companies. As consumers become aware and then convinced of the merits of home and building controls, technological prowess should be at the forefront of decisions. One thing that you can be sure of is that KNX will still be the centre of it all. KNX is in the enviable position of being able to talk to any system already. With the very consumer facing promotion of smart tech from Hive, Nest, Apple and Echo, you could be misled into believing that this is all new. The background in not, but the funding for awareness is. Smart tech for your lives will permeate all aspects of how we live. Once initial desire has been satiated by a new glass thermostat, what next? Do you continue with NEST and buy a light switch, smoke detector or compatible light source? What do you do when NEST does not have a complete solution? For installers, the opportunity comes with the ability to integrate a NEST thermostat into a complete solution. KNX has a long history with no changes in protocol. KNX is considered to be the primary control network in buildings. The IoT side of KNX has been in use for 10 years. All of these conspire to make KNX the natural choice for the centre of your building’s control network. With increased awareness comes a higher demand for solutions. KNX has that in abundance, and has had 26 years of proof of just that. So how does KNX stand out from the crowd? KNX is the world’s only truly open protocol system endorsed by worldwide standards. It is regulated by the KNX Association of Brussels and supported by world leading manufacturers within the electrical industry. In fact, there is a huge choice of over 7,000 approved KNX products from more than 400 manufacturers, covering all aspects of building control and automation.

The underlying philosophy of KNX is to bring these different manufacturers’ products and brands together on one bus network and to be completely interoperable with each other. KNX is not only fully interoperable between manufacturers and their associated products, but also at the heart of building-wide integration of control applications. KNX can be designed building-wide since it acts as the underlying bus technology for most control applications, all operating together on the same bus network. Integration is all about these applications working together and allowing them to share information about the space being controlled. There is no limit to the size and scale of the KNX system as the technology is equally well suited to large-scale projects and small residential projects alike. In terms of device limits, one KNX line can support up to 64, devices using a single power supply. These lines can be repeated and cascaded to include many lines of 64 and when using IP as the backbone, the system is virtually limitless. The best way to stay engaged with KNX technology, and the community, is by joining the KNX UK Association. There are five full membership categories, including manufacturers, integrators, training providers, wholesalers and associated members. In addition to the membership groups, we have the KNX UK professional group, for those wishing to participate in networking events. As part of the membership fee, we offer a great range of resources to members. These include extensive marketing and PR support, including visibility through our KNX UK Awards scheme, a company listing on our website, which is accessed by consumers and specifiers, the chance to attend training and networking events with the KNX community, and speaking slots at shows such as Vision London and UK Construction Week, amongst others. KNX UK represents manufacturers, integrators, wholesalers and training establishments associated with KNX open standard control technology for commercial and residential applications within the UK.
