LG CHEM OLED LIGHT PANELS HAVE BEEN USED TO CREATE PENDANT LAMPS AT A NEW POP UP RESTAURANT, TINCAN
L
G Chem OLED Light panels have been used as the main light source at Tincan, a newly opened pop-up restaurant designed by AL_A. The restaurant which was introduced in time for this year’s London Design Festival, serves an exquisite collection of tinned seafood along with carefully selected beer and wine. The decision to use LG Chem OLEDs for the restaurant’s lighting was based on the excellent light quality as well as the design possibilities unique to OLEDs. Moreover, the simplicity of OLEDs enabled the architectural design firm, AL_A, to design and manufacture the lightings themselves. “It is very easy for us to be creative and think of new designs. It is a ‘simply plug-and-play’ element. It opens a whole new world of possibilities” says Maximiliano Arrocet, a director at AL_A. The actual lamp was prototyped using 3D printing. Although the final products were created through aluminum spin forming, the designers at AL_A admit that the 3D printed version could have well been the final product.
company with three main businesses: Petrochemicals, IT & Electronic Materials, and Energy Solution. With sales over $23 billion, LG Chem employs over 20,000 people in 15 countries.

Kevin McCann
LE: How DALI professionally enables easy and intelligent management of lighting Equipment? DALI: The DALI protocol is a worldwide standard for lighting control. It provides lighting control specific requirements that are not found in other protocols, and includes standardisation of control gear for all common lamp types. DALI allows a choice of individual, grouped or broadcast communication, providing control, configuration and feedback to/from lighting devices. Flexibility in system design is built-in, allowing very simple systems using broadcast levels without any configuration, to systems that make use of the fully automated DALI emergency lighting testing and reporting. Regardless of whether the system operation is simple or rich in functionality, the requirement is the same commonly available 2-core 1.5mm2 bus cable, which is used for communications as well as supplying bus-powered devices.
Wireless can also be used in a DALI system– for example by using an interface (gateway) between the wireless devices such as buttons and sensors, and the DALI network. This can provide the convenience of wireless together with the reliability and low cost of wired connections to luminaires. Interfaces to many protocols are available, and more are still being added. Examples include TCP/ IP, BACnet and KNX. LE: What part of the DALI is? Especially for the German Electrical and Electronical Manufacturers Association? Or its for the Worldwide members from the lighting industry? DALI: DALI is a global standard. Due to the growth of LED, the increasing demand for energy saving and growing awareness of lighting control systems, DALI has become world-wide more important than ever before. Today, with almost 130 international members, DALI is a global standard for professional digital lighting. Our focus was and will always remain international. LE: How big is the lamp and luminaire control market in Germany, and there presence in the International market? DALI: Pertaining to Germany, the lamp and luminaire control market is traditionally a very strong market with a high and well-recognised position in the international market itself. But nevertheless this reputation, in 2013 the German lamp and luminaire control market had to deal with a decreasing trend. While domestic sales stay on the previous year level,
export sales are currently influenced by a weak economy situation. On the contrary, the DALI protocol itself shows a growing, worldwide success. This is a result of the blurred borderline between sale of single luminaires and the increasing sales number of electronic control systems, such as DALI. In the recent years the DALI protocol shared represented approximately 50% out of all dimmable LED & fluorescent control gear. This shows that the DALI protocol is not only becoming the true standard for professional lighting in Europe. Also international regions recognise and show their interest in the DALI technology. LE: Lighting Control systems which we believe to be very important in the field of energy saving and growing awareness of lighting control, how DALI can help local manufacturers for this? DALI: DALI was developed as an international industry standard for intelligent and easy management of lighting equipment. The standard incorporates several parts that provide control and monitoring functionality for ballasts, emergency gear and LED gear, expanding to lighting controls in the near future. Compared to a fixed output installation, the dimming and individual control capability provided by DALI enables considerable energy savings. In combination with dimmable drivers, presence and daylight sensors, energy savings of up to 80 per cent can be achieved. If the operation of the lighting is to be rearranged or regrouped, the costs per circuit in a fixed output system could be four
times higher than those in a DALI system. The ability to send queries and obtain replies – two-way communication – can greatly reduce maintenance costs. For example, DALI allows automatic testing and reporting of monthly function tests of emergency lighting. In addition, energy consumption and lamp condition can be checked for each luminaire, very easily and at no additional cost. LE: What sort of membership are you the membership? Is there any fee involved? DALI: The membership in the DALI working party of ZVEI is open for Companies, if and when they pertain to the electrical or electronic industry and pursue an activity in the lighting industry. Organizations may also qualify for membership in the Working Party, if and when they pursue an activity in the field of the Working Party. Currently the annual membership fee is 5000€. The membership fee covers not only the right to use the DALI logo on compliant-tested products. According to that, the DALI membership offers a broad range of benefits for its members. For example, the contribution in the Technical Working Group allows to evolve the standard for DALI and help to support the development and to ensure the interoperability of the standard. Also participation and contribution in the DALI Marketing Working Group allows to evolve marketing strategies and help to promote the DALI standard as the de-facto lighting management system.

lamp clustering according to specific requirements as well as setting various control algorithms for various lamp groups; when the same installation is used to power both estate streets and busier roads there are different energy saving options set to ensure the roads are lit according to standards and regulations, calculating electricity consumption for individual lamps, clusters of lamps or additional equipment powered by the same power source, e.g. christmas lights, street lamps operation monitoring; in the event of malfunction the system can notify an operator or service teams of the need for intervention e.g. by sending a text message,

good, there is no need for a lighting system to operate at full power. The system is able to reduce lighting parameters or completely switch off some of the lamps (even though switching off some lamps is contrary to the principle of maintaining street lighting continuity, it is allowed in certain cases). Such systems allow a significant reduction in electricity consumption and therefore contribute to substantial savings – the current installation in Oslo confirms savings of up to 70%. A very important factor in using such systems is that they can be easily implemented within the existing lighting installations. The system allows calculating energy consumption for several customers, e.g. less operators responsible for lighting an area powered by the same installation, offering access to the control system independently for each of the customers. Technology The GLC system operates using Echelon's LonWorks technology.
System Green Light reduces lighting parameters whenever possible. For example, if traffic is low, e.g. late at night and the weather conditions are

Utilising an open communication standard allows using equipment from various manufacturers. There is no need to get attached to only one manufacturer which allows choosing the best solution available on the market when implementing subsequent investments – there is no risk that new system elements won't communicate with the old ones. Communication between Smart Lighting modules uses cables powering street lamps (LonWorks Power Line Communication, in short PLC) therefore installation does not require additional workload associated with laying cables to connect individual lamps. In many cases this would be difficult and would involve planning and construction works and very often could even prove impossible. APANET Green System sp. z o.o. ul. sw.

NEW IDEAS IN LIGHTING GET CLOSER TO MARKET
E
ver since government regulations began phasing out the traditional light bulb in 2012, the once-simple visit to the lighting aisle has become an exercise in navigating a dizzying array of choices and terminologies, especially for new kinds of compact fluorescents and LEDs. Now, those choices are about to become even more complicated. Two start-up companies are poised to begin selling bulbs that use entirely different technologies — one borrowed from heavy industry and the other from old-fashioned televisions — but meet the new energy standards. Whether they can capture customers who remain stubbornly wedded to incandescent light is anybody’s guess. But that both have come this far is an indication of how unsettled the consumer lighting market remains, despite years of promotion for the new energy-saving options. Philips sells a range of energyenhancing lights, including the goLITE BLU, a panel of blue LEDs.Gadgetwise: LEDs Change Thinking About the Light BulbFEB. 5, 2014 “It’s going to be a really long putt to try to replace the incandescent,” said Mark Rea, director of the Lighting Research Center at Rensselaer Polytechnic Institute. “People hate change of any kind. We make light sources today that are better than incandescent by any metric at delivering the benefits you’re expecting from lighting. But it’s different.” Indeed, incandescent bulbs —
whether leftover store inventory of standard lights or halogen models that meet the new regulations, which went fully into effect in January — outsell other types by far at big-box stores like Home Depot and Lowe’s, lighting executives there say. In the last quarter of 2013, according to statistics from the National Electrical Manufacturers Association, incandescent bulbs accounted for 65 percent of shipments from manufacturers, with the remainder consisting of mainly compact fluorescents. Even as government officials, manufacturers and retailers focus their efforts on improving and marketing LED technology, researchers and entrepreneurs have been pursuing others, convinced that none of the options on the market offer consumers a close enough match to the familiar light quality at a low enough price. LED bulbs, for example, offer light quality that many experts say is equal to or better than the traditional incandescent bulbs, but their price — often $10 a bulb or less after starting out several years ago at about twice that — has scared off consumers. “We have evolved as a species under daylight during the day and the incandescent light at night in the form of fires and candles and then oil lamps and finally incandescent lighting,” said Konstantinos Papamichael, co-director of the California Lighting Technology Center at the University of California, Davis. “I would find it hard for people to enthusiastically move into new technologies without getting something similar to what they have.”
So at a small demonstration lab here, just outside Boston, a glass artist in dark goggles blows specially designed tubes, one tiny component of a new bulb to be called Finally when it makes it to store shelves. A few yards away, a scientist examines multicolored graphs representing the spectrum of colors the bulb emits. And over in a corner, dozens of the lights glow upside down, part of the company’s quality control. It is all part of the quest of John Goscha, who already has one successful start-up company under his belt, to build a better light bulb. Mr. Goscha, 30, started a custom golf-club business in high school and founded IdeaPaint, which allows most surfaces to function as dry-erase boards, as an undergraduate at Babson College. The Finally bulb will be $8, competitive with some of the cheapest LEDs on the market. Credit Rick Friedman for The New York Times But IdeaPaint grew up, he said, and about three years ago he was eager to do something new. “I took a couple of months and just tried to kind of open my blinders and say, ‘Hey what’s going on in the world,' ” he said. Around that time, a friend mentioned the incandescent phaseout, of which he had been unaware. Unhappy as a consumer with compact fluorescents and LEDs, he said, he decided to pursue making an alternative. “I thought, ‘I don’t really want those and there have got to be other people who don’t want those either,’ ” he said. Looking for the solution, he began attending conferences and meetings

and enlisted the advice of Victor Roberts, a former General Electric engineer who eventually joined the venture. On a flight to Hong Kong, the two talked about induction, a technology that has many applications, including electric motors in home appliances and construction cranes because it is long-lasting. But it had not yet been widely adapted for home use in lighting because it was difficult and expensive to fit the electronics needed for bright, omnidirectional light inside a regular bulb. With the advent of smaller transistors and other advances, though, the company, which has hired engineers from established light makers like Osram Sylvania and Philips, shrank the apparatus to a three-inch antenna wrapped in copper wire. That creates a magnetic field inside the bulb that prods mercury to produce ultraviolet light, which in turn creates visible light when it interacts with a special phosphor coating the glass. The result, to be manufactured in India, has almost all of its regulatory approvals. It can be disposed of in landfills despite its mercury content because the amount of metal is minuscule and in solid, not liquid, form. It also has received approval from the Federal Communications Commission because the antenna is technically a radio receiver, albeit a weak one. Mr. Goscha plans to sell the bulb for $8, making it competitive with some of the cheapest LEDs on the market. But although it has shown enough promise to have attracted about $19 million from investors, including some of Mr. Goscha’s Babson
professors and interest from bigbox retailers, its path is not yet cleared. Take, for instance, the Vu1, a bulb that was supposed to come to market more than three years ago. It was available for a time on the Lowe’s website but had production problems and was withdrawn. With new manufacturing operations in China rather than the Czech Republic, said William B. Smith, the company’s chief executive, it is only now ready to begin shipping to stores. “This is all self-inflicted self-hatred,” Mr. Smith said jokingly about the company’s missteps, which included losing Wall Street backing after missing too many deadlines. “Whenever you move a technology from one country to another, it never goes as planned.” Mr. Smith said he was largely financing the company himself while it struggled to get on better footing. The Vu1, which will be available first for use in recessed fixtures, uses a technology like that of cathode ray tubes in televisions, a “state-of-theart 1940s technology,” Mr. Smith said, in which electrons hit a cocktail of phosphors on the glass, which then glows. But the light’s long journey to stores shows how difficult it can be to make a new light bulb and how elusive the promise of new technologies can be. Researchers, seeing a market that is wide open, are still working on even more technologies, including plasma and so-called organic LEDs, which spread light over a flexible surface. “Twenty years from now, we’ll walk into a room and OLED is going to be covering your entire ceiling and it’s going to dim automatically and it’s going to be able to figure out your mood and it’s great,” Mr. Smith said. “Thanks, Captain Kirk. But we’re not there.”

White Light Color Tuning Offers a New Dimension of Lighting Control BY CRAIG DILOUIE
14 | Hong Kong Interntional Lighting Show 2014 Special | lightexpress
“Light is comprised of wavelengths that the human eye interprets as colors. For an object to be perceived a certain color, that color must be present both in the light striking an object and the object reflecting the light towards the observer’s eye. Because of this, the choice of lamp for white-light general lighting can influence how colors are perceived in a space. This means that perception of objects in the space is, to an extent, controllable.” Traditionally, this level of control was extremely limited. To change the shade of white from warm (about <3000K) to neutral (about 3500K) to cool (about >4000K), we would essentially have three choices: 1) change the lamp, 2) add a color filter to a luminaire, or 3) separately control layers of warm and cool lamps. These options could be expensive and offered limited flexibility. In contrast, solid-state lighting offers new possibilities for controlling color temperature. This would involve a master controller to control the system, DMX, DALI or other interface between the master controller and each LED product, and LED products with separately dimmable arrays of warm and cool LEDs or separately dimmable colors mixed with white. Depending on the LED product, it may 1) provide programmable and user color tuning, 2) imitate the warm color of incandescent lamps when dimmed, and/or 3) offer precise color matching between LED products and calibrate to maintain constant color output over their life. Focusing on the first option, why should we care? The simple answer is the color qualities of a light source can affect the appearance of a space. In some applications, color is critical. In a high-end retail application, good color quality can make products, especially clothing, appear more vibrant, truer and ultimately more appealing. In an office application, color quality can facilitate social interaction by
rendering faces more naturally and thereby helping to create a more productive and appealing work environment. In a healthcare application, good color choices can make guests feel more welcome by imitating the warm lighting conditions of home, while rendering skins more effective to help detect illness (jaundice, rash, infection, fever, etc.).

Visa Lighting’s LED Unity recessed over-bed units are multifunction luminaires for hospital patient care rooms. Unity provides separately controlled reading, ambient, and exam lighting, as well as enhanced blue spectrum, amber night light and RGB visual interest. Image courtesy of Visa Lighting. The list goes on. Think about the application: Do you want it to be visually warm or visually cool? The right color temperature is often a matter of psychology—both preference and tradition—with due consideration for emphasizing (and not distorting) dominant colors in the space and properly rendering color contrasts that make tasks more visible or call out safety markings and instructions. When making a case for a light source, particularly as a retrofit option for an existing building, it’s highly beneficial to make an economic argument that goes beyond energy and maintenance savings. If the designer can effectively connect economic benefits to various aspects of lighting quality, the owner will be more amenable to paying more for these choices because they will perceive a return on investment. Color is one such area. As one small example, consider the results of
three German experiments in which more than 500 people tasted white Riesling wines under different lighting conditions. The researchers used a series of fluorescent lamps that produced red, blue, green or white light. People rated the wine’s quality higher, in general, when they drank it in a room whose ambient lighting was red or blue versus green or white. They also found the test wine much sweeter and fruitier when sampled in a room lighted with fluorescent lamps with a warmer color tone, and were willing to spend more for it.
or subtle colors. Image courtesy of Acuity Brands. Now consider an office building where general lighting in daylighted spaces could automatically adjust to blend electric light with daylight, or where general lighting in nondaylighted spaces could automatically adjust to match the actual or idealized daylight cycle, providing visual cues about time of day. In meeting spaces, color output could be manually adjusted to adapt the space for different functions such as business meetings and social events.
The problem is the right choice of color temperature is not always clear. The challenge becomes more significant in spaces that would benefit from different shades of white (and other colors) depending on different functions or times of day or year.
Finally, imagine a hospitality space where color and décor are critical; the designer could tune the color output with the owner and other designers to achieve a precise space appearance after the final colors and materials are selected and the luminaires are installed. And later, at any time, to accommodate future changes. In a restaurant, color output could be adjusted from cool lighting during business luncheon events to warm lighting for evening dining.
A survey of lighting designers and specifiers conducted by the National Lighting Product Information Program revealed that for retail applications, light source color properties are considered more important than any other light source criterion, including energy efficiency. Now imagine a light source that could be tuned—precisely, exactly where you want it—to optimize presentation of various merchandise displays. Color output could change based on time of day, as merchandise displays change, or fashion season. In change rooms, color output could be manually adjusted by customers to view themselves under different lighting conditions. Aera by Acuity Brands.

The proliferation of solid-state lighting, however, is making that choice flexible and dynamic. The result is the ability to fine-tune the color quality of lighting for significant application benefit and intriguing possibilities awaiting exploration.

TSMC Solid State Lighting Ltd.
T
SMC Solid State Lighting Ltd. (TSMC SSL) introduced Phosphor-on-Die (PoD) technology and its applications at the Frankfurt Light+Building 2014 with ambitious plans to fulfill the high-end requirements in lighting markets. After PoD technology and TR series modules were announced in 2013, TSMC SSL began a series of projects with customers implementing this technology to their fixtures. These new applications also unveiled at Light+Building 2014. PoD technology applies TSMC SSL’s own flip-chip LED dies and encapsulates them in a phosphor coating. Its characteristics such as chip scale size, high lumen density, wide 150-degree viewing angle, consistent color temperatures and feasible high-voltage design allow fixture designers to overcome current LED light source limitations and fulfill their needs for innovative and versatile fixtures. At TSMC SSL booth, visitors will find PoD modules
in point light source fixtures such as PAR and MR16 (T2- & TR-series), light bars and panels (TL-series) as well as dimmable and CCT tunable fixtures. TR and T2 point light source modules can allow for a small light emitting surface from PoD’s small form factor and provide consistent color temperature, enabling fixture designers to simplify their designs and create excellent light quality: free from multi-shadows as well as a high center beam candle power (CBCP). TL-series light bars and panels utilize PoD’s feature of wide emitting angle to effectively decrease optical distance and deliver a highly uniform light distribution with fewer LED emitters. PoD is the best solution to CCT tunable and dimmable fixtures. By taking full advantage of PoD’s small form factor, various emitters of different color temperatures can be applied in a compact form on a single CCT tunable light module, at
the same time enabling superior uniform color mixing and a high lumen density. PoD is also an excellent choice for Driver-on-Board (DoB) applied in dimmable fixtures. In contrast to traditional bulky LED packages, the design of light board can be optimized to deliver uniform, dark spot-free dimming performance. The products and applications will be demonstrated at TSMC SSL booth located at hall 10.1 booth D39 at the 2014 Frankfurt Light+Building during 3/30 to 4/4.

EUTRAC Stromschienen GmbH
Safety and elegance: The in-trac adapter by EUTARC is the first adapter to be recessed fully flush into lighting tracks
E
UTRAC also develops new, creative approaches for everyday lighting technology products. One example is its classic adapter for mounting of luminaires on 3-circuit tracks. At Light+Building 2014 EUTRAC EUTRAC presentED the in-trac adapter, an adapter that can be submerged so it sits entirely flush in track profile – while still boasting state-of-the art technical features. As flexible and safe lighting infrastructures, track systems such as 3-curcuit tracks by EUTRAC, whereby luminaires are connected via an track adapter, have never been more popular. Following intensive work by its developers, EUTRAC can now present the new in-trac adapter, the first ever adapter to be sunk entirely flush into the track. Its minimal shape provides entirely new scope for design for lighting engineers and designers of trackmounted luminaires, from spotlights to pendant light fixtures. Here the adapter takes a step back as a design element, allowing the luminaire itself to come to the fore, thereby achieving its full effect. Premium technology on the smallest of spaces With the in-trac adapter, EUTRAC has
developed a product that fully does justice to technical requirements wherever space is limited. The luminaire is connected without the use of punch-down technology and approved for inductive or ohmic loads of up to 6A, with a voltage of 250V. The adapter provides an earth connection while circuit can be selected via a slide switch before insertion into the electric track. Electric contact is made by pressing on the side locking lever, which at the same time locks the adapter securely into the track profile. The housing is made of sturdy polycarbonate, while the retaining collar allows the luminaire head to be rotated 360°. Future-reliability too The in-trac adapter also allows for integration of controllable luminaires in light management systems like EUTRAC NetComposer - a databus connector for the EUTRAC DALI track can be ordered separately.

Using Less Energy ENERGY EFFICIENCY: LIGHTING
I
t takes a lot of energy to light up the world. Lighting is responsible for 19% of electricity use worldwide. In the United States alone, lighting accounts for almost 25% percent of electricity use in homes, and about 13% in offices,
stores, schools, and other commercial buildings. Clearly, reducing the amount of energy used for lighting would make us more energy efficient. But modern society relies on electric lights so we can remain active at all hours of the day and night. What makes current lighting systems so inefficient? The easiest and most obvious step to save energy is to turn off lights that are not in use. While that helps,
it does not solve the problem. The big question is, how can we make artificial lighting more energy efficient?
manufacture and come in all kinds of shapes and sizes. Many different types of lighting fixtures are designed to fit the screw-in base of this type of bulb.
What We Currently Use Most electric light fixtures use either incandescent or fluorescent lightbulbs, or lamps, as the light source. Incandescent lamps produce a pleasing warm light. They are relatively inexpensive to
32 | Hong Kong Interntional Lighting Show 2014 Special | lightexpress
The incandescent lamp consists of a large glass bulb attached to a metal base that serves as the electrical contact. The outside of the base is threaded, to be screwed into the light fixture. The hollow glass bulb contains a metal wire called a
filament—the filament is made of tungsten—attached to the electrical contacts in the base of the bulb. The filament is very long—about 2 m (6.5 ft) in a standard bulb—but extremely thin, at about 0.254 mm (0.01 in). The wire is very tightly coiled and that coil is then wound again, to fit inside the bulb. An inert gas such as argon fills the inside of the bulb. When an electrical current runs through the filament, it heats up and glows. Fluorescent light fixtures have long been used in offices, stores, and classrooms. The light is cool and bright, and does not produce a lot of extra hear. There are a number of drawbacks to incandescent lamps. The tungsten evaporates over time of use, weakening the filament until it breaks. At that point the lamp no longer works and needs to be replaced. A 100-watt incandescent lamp is rated to last 750 hours, not a very long time. However, the biggest issue for incandescent lamps is that
they are not very energy efficient: they produce heat as well as light. This heat escapes into the surrounding environment. In fact, incandescents produce the least light for the amount of energy used to power them. This makes them huge wasters of energy. The halogen lamp is another type of incandescent light bulb. Halogen lamps also use a tungsten filament, but a hollow quartz covering (quartz is much harder than glass) filled with halogen gas encloses the filament. When the filament heats up, the halogen gas reacts with tungsten vapor, redepositing tungsten atoms back on the filament. This enables the filament to last much longer, and to be heated to a hotter temperature. Thus a halogen lamp lasts longer than a standard incandescent and gives off light that is brighter and purer in color. However, halogen lamps get extremely hot, much more so than standard incandescent lamps. That means that halogen lamps are also energy wasters. Fluorescent lamps, the other
common type of electric lightbulb, are much more efficient than incandescent lamps. Fluorescents use approximately 30% of the energy of an incandescent bulb to produce the same amount of light. They are commonly found in institutional settings: schools, offices, stores, and public buildings. Lighting fixtures that use fluorescent lamps are cheaper to operate, and they produce a fair amount of light for the money. Compact Fluorescent Lightbulbs The compact fluorescent bulb uses the same process as a traditional fluorescent tube, but uses a smaller spiral shape and a screw-in base that allows it to fit into fixtures made for incandescent bulbs. The compact fluorescent lightbulb (CFL) is one very popular option for reducing lighting costs. The CFL is a fluorescent lamp manufactured to fit the same fixtures as incandescent bulbs. This type of lamp has been available since the early 1980s but is
only now catching on with consumers. The big advantage: CFLs use much less electricity—70% to 75% less, according to some sources. CFLs have the same energy-saving advantages of standard fluorescent lamps. But only now are these lamps being used regularly. Why? The early CFLs were terrible. The light they produced was dim and dull, with an awful color. On top of that the lamps took a long time to reach full power, and even at full power, they flickered. Today’s CFLs are much better. The color has been softened, the light is no longer dim, and the lamps start up much more quickly. The improvements have resulted in greater popularity with consumers. In fact, some countries, including Australia and Canada, have mandated that consumers switch from incandescent lamps to CFLs by specific dates. Other countries are also encouraging consumers to make the switch to save energy. CFLs are not perfect replacements
lightexpress | Hong Kong Interntional Lighting Show 2014 Special | 33
for incandescent lamps. Many consumers do not like the light these lamps produce, despite the vast improvements in the last few years. And the lamps still take some time to warm up to full power. Like their long-tube predecessors, CFLs contain a very small amount, usually 4 to 5 mg (0.00014 to 0.00018 oz), of mercury, a toxin. If the lamp breaks the mercury enters the general environment. A portion of that mercury evaporates, but so little enters the environment that researchers believe it poses little or no danger. Proper cleanup and disposal of the broken lamp takes care of the rest of the mercury. Light-Emitting Diodes Another promising approach is the use of light-emitting diodes (LEDs) for interior lighting. LEDs are commonly used already for many things, such as digital clocks and the lights on light-up wristwatches. But now these little lights are being used in lamps, to replace incandescent bulbs for interior lighting. The LED bulb is the newest type of lower-energy lamp projected to replace incandescent bulbs. Made from durable plastic, an LED bulb uses the movement of energy in a semiconductor material to create light. LEDs use a different technology from incandescent and fluorescent lamps. Instead of relying on a filament that gets used up or electrodes with a limited number of starts, LEDs produce light by the movement of electrons in a semiconductor, a material or compound that allows some flow of electricity. Electricity is sent to a diode made of a semiconducting material, causing the electrons to increase in energy level. As the electrons drop back down to normal levels, they release photons, or light energy. The color of the light depends on the material used in the diode. A silicon diode produces infrared light, but other materials produce different colors in the spectrum. In addition, the semiconductor material used for the diode must be one that does not
absorb the photons, but releases them outward, to produce light. The light coming from the diode goes every which way, but the lamp has a plastic cover, which concentrates the light. Individual diodes are not bright. Thus they are grouped together in lamps, to produce the desired amount of light for the bulb. LED lamps have many advantages over other types of lighting. They are made of durable plastic, not morebreakable glass. LED lamps do not burn out the same way as lamps that use filaments. The diode does degrade, producing less light after thousands of hours of use. But the bulbs are long-lasting, with a lifetime between 50,000 and 100,000 hours until the degradation of light becomes noticeable. The small size of LEDs fits modern electronics. Most important, LEDs are energy efficient. Much more of the energy is used to create light and not wasted heat. LEDs are not without disadvantages. Until very recently they were prohibitively expensive, reflecting the cost of the semiconductor material. The material price has started dropping, but the lamps remain significantly more expensive than traditional lamps. For example, in 2009 a standard incandescent bulb was around US$0.75 per bulb, while a replacement LED bulb was US$45. The longer life of the LED balances out some of the expense. The quality of light given off by LED lamps poses a more significant problem. The light tends to be diffuse—it does not focus well for spot lighting. Color also remains an issue. LED lamps produce excellent shades of red, green, blue, purple, pink, and a very bright white. Because of this, LEDs are increasingly being used for dramatic and colorful interior and exterior architectural lighting, including holiday lights.
Daylighting Natural light is a very important source of energy-efficient light. Architects and builders are making more use of daylight, working with lighting designers to help place windows and skylights in new homes or commercial buildings. Modern double-paned windows can keep the cold out during the winter, although not as effectively as insulated walls, and with special coatings to reflect light, they can prevent interiors from heating up too much during hot summers. Newer buildings use natural daylight Photo courtesy of David Joseph/ Lawrence Berkeley National Lab– David Joseph/The New York Times Newer buildings use natural daylight to light interior spaces as a way to save energy. Lighting designers help place windows in locations that will make the best use of light without burdening the building with extra heating or cooling costs. For example, north-facing windows let in even light year-round, while south-facing windows maximize light in winter; neither lets in much glare. Proper roof overhang and planting of trees can prevent extra heat coming in during in the summer in windows that receive direct sunlight. West- and east-facing windows are avoided as much as possible, because they let in light and heat, as well as glare.
However, LED technology thus far has not been able to produce a light similar to daylight. The very harsh light of a white LED makes colors look odd. Researchers continue to work on developing an LED lamp that can produce a color similar to daylight.
34 | Hong Kong Interntional Lighting Show 2014 Special | lightexpress
Skylights also let in light without too much heat, if positioned and installed properly. The skylight must have a slope that maximizes winter heat and lessens summer heat. Installation must be done carefully, to prevent leaking during rainstorms. Down the Road Motion-detector lights have a sensor that switches on the light when movement occurs within the sensing field. When the motion stops, after a certain time the light switches off. Light fixtures with this feature are commonly used on building exteriors, as a way to have light only when it is needed. Installation of this type of fixture in building interiors for rooms that are not in regular use, such as storage rooms, is one way to save energy; this type of use is on the rise. Researchers are looking at ways to make lighting even more energy efficient. One technology under development would channel the light from the Sun to the interior of buildings through “light pipes” that contain reflectors. Another technology uses fiber optics to bring in light, combining solar lighting and standard electric lights. In this project electricity takes over when sunlight decreases to a certain level. These and other technologies are all in the early stages of research.
Japanese designer designed a LED wooden light bulb
A Young Japanese designer Ryosuke Fukusada designed a light bulb, at first glance it like a wood carving bulb, but in fact it is hand-built LED lights! It exudes a unique feeling by this modern technology. Ryosuke Fukusada adopted Japanese traditional woodcarving techniques named â&#x20AC;&#x153;Rokuroâ&#x20AC;?, it places the pine on a rotating lathe, and then cuts the pine to the thinnest thickness of only 2-3 mm, finally the light beam can penetrate the thin wood layer, also with original wood texture, it is like the burning visual. In addition, Ryosuke Fukusada chose cold LED lights specially, so do not worry about overheat may damage the wood surface, and also can emit a warm light. This LED wooden light bulb was awarded with the Kyoto renaissance design competition, and the complex manual production makes this bulb sold at very expensive price at 2,000 euros. lightexpress | Hong Kong Interntional Lighting Show 2014 Special | 35

DAYLIGHTING, DE-LAMPING AND OPTIMISATION from fittings where the light output exceeds what is required. If the light fitting is inefficient, it can be improved with a reflector. Many fluorescent light fittings hold two tubes so reducing the number of lamps saves up to 50% in lighting energy. De-lamping can result in significant energy savings at very low costs and also reduce air conditioner cooling loads, reduce lamp replacement costs, and decrease circuit loading due to lower electricity demand. There are good de-lamping opportunities in toilets, kitchens, offices, corridors, stairwells, meeting rooms (often over-specified for lighting), copying rooms, waiting rooms, store rooms, and near windows in buildings not used at night.
T
here are a number of strategies to improve lighting energy efficiency that can be implemented alongside a technology upgrade. Switch-off behaviours Improving staff switch-off practices for lights applies to meeting rooms and bathrooms as well as at night and over the weekends. The techniques and tips provided for behaviour change all apply to lighting as well as equipment. For lighting in particular, energy managers may need to explain to staff that leaving fluorescent lights on does not save energy compared to switching them off and on more often. Other methods like stickers, signs, and appointing people to switch off at the end of the day can all prevent energy waste.
The steps to undertake de-lamping are: REDUCE DEMAND FOR ARTIFICIAL LIGHT Also known as â&#x20AC;&#x2DC;daylightingâ&#x20AC;&#x2122; there are a number of techniques for making use of available light rather than artificial. Techniques include choosing light colours for internal surfaces and walls, skylights, shading device control, glare reduction and electrochromic glazing. Giving more access to daylight has also been shown to increase productivity. OPTIMISE EXISTING LIGHTING SYSTEMS As well as switch-off behaviours, there are other ways to get the best use out of existing lights. For example: Cleaning off dust build-up from
lamps, reflectors and diffuser panels. Installing light switches in individual offices, rearranging lighting circuits to align with work areas or to group lights in daylit areas. Replacing discharge lights (e.g. ballasted mercury vapour) with lights with a shorter time to switch on after power interruption (compact fluorescent or LED light fittings). Making use of lighting control systems where they are installed, that can program lights according to time of day, daylight and occupancy. Creating smaller zones (100m2) so that one switch controls fewer lights. DE-LAMPING De-lamping means removing lamps
measure existing illumination levels (using a lux meter and building plan) compare illumination levels with minimum recommended standards and identify over-illuminated areas de-lamp appropriate areas. More detail and data to help diagnose when de-lamping is appropriate are included in the CitySwitch Workbook and CitySwitch Lighting Audit Toolkit.
The Commonwealth Government's Energy Efficiency Exchange and the NSW Lighting Technology Report also have user-friendly guides to lighting. For de-lamping exercises, disposing toxic waste from mercury vapour and fluorescent tubes can be avoided by a number of recycling schemes.

OLED luminaire OLED panel: soon at the same level as LED An exciting fair highlight: an OLED facilitating LED-like efficiency in lighting. One of the essential factors supporting the breakthrough of OLED lighting. The new generation of the Orbeos OLED panel by OSRAM, with 65 Lumens per Watt has not yet achieved the efficiency of LED chips but is already more efficient than energy-saving lamps. However, LEDs when used in luminaires, require optics that reduce glare and direct the light. These factors are at the cost of efficiency, and thus the efficiency advantage is reduced. To get a taste of OLED applications in general lighting, OSRAM is presenting an OLED luminaire at light+building 2014 designed by Werner Aisslinger, who was recently declared Designer of the Year 2014 by the magazine "Architektur & Wohnen". The pendant luminaire with a sophisticated appearance is equipped with 16 rectangular OLED panels and is ideal for use in conference rooms and hotel lobbies.

LEDs Change Thinking About the Light Bulb LIGHTS ARE NO LONGER JUST FOR LIGHTING.
W
ith the development of LED lamp technology, the lowly light bulb is doing more than turning on and off. A lamp can be the centerpiece of an environment meant to improve health, moods and even food. LEDs can create light in multiple colors, generate less heat and use a fraction of the energy of older types of bulbs. And LEDs can be controlled remotely from a PC or smartphone app, as programmable as a television. “There’s a tremendous potential for LED lighting to go beyond illumination,” said John Strainic, General Electric’s general manager for consumer lighting. “We’re asking people to think about lighting as more than just an impulse purchase.” Because of the LED manufacturing process, the light that the technology creates is weighted toward the blue end of the spectrum. That is true whether the LED is used in a light bulb, a tablet or a television display. That blue light has its advantages: Blue stimulates a photoreceptor in the eye that reduces melatonin production and helps a person stay awake. Tabu’s Lumen TL800 lamp uses Bluetooth connectivity to control the lamp from a smartphone, allowing the user to change colors, dim the bulb and synchronize lighting effects to the rhythm of a song played on the phone. “You have to start thinking of light as a drug,” said Terry K. McGowan, the director of engineering for the American Lighting Association, a trade group.
That is why Lighting Science, an LED manufacturer, is now selling Awake and Alert, an LED lamp that keeps people pumped up by pumping up the blue. Conversely, the company’s Good Night lighting product reduces the blue output, helping people sleep. This summer, Lighting Science will offer its Rhythm Downlight, a lamp controlled by a smartphone app that adjusts blue light based on a user’s sleep schedule. “The Awake and Alert lamp does not look brighter, but our circadian system sees it as such,” said Robert Soler, Lighting Science’s director of lighting research. “We always felt that there was so much more you can do with light than just increase vision.” Philips sells its own range of energyenhancing lights, including its Wakeup Light and — to combat winter blues — the goLITE BLU, a panel of blue LEDs. In Europe, Philips is experimenting with its HealWell system in hospitals. By changing colors based on time of day, it encourages a patient to wake up, feel more relaxed and sleep more easily. At a field study at the Maastricht University Medical Center in the Netherlands, cardiology patients were found to sleep longer and experience reduced depression. In the United States, Lighting Science is working on a similar system, and expects to offer products by the end of this year. “Unfortunately, many hospitals have removed solariums, but lots of studies have shown that they improve recovery time,” said Mr. Soler of Lighting Science.
While the ability to alter an LED lamp’s color opens up new uses for light, the fact that LEDs can be remotely controlled significantly changes their potential. The Awake and Alert, an LED lamp from Lighting Science, pumps out blue light, which stimulates a photoreceptor in the eye that reduces melatonin production and helps a person stay awake.
maturation time while reducing energy costs. “We find the optimal light recipe for the grower,” said Udo van Slooten, a Philips Lighting general manager for horticulture. Within the next few years, the world’s major lighting companies expect to expand LEDs’ connected capabilities, particularly with sensors.
With Osram Sylvania’s ULTRA iQ system, users can program lamps to turn on when a key is put in the lock. Philips’s Hue system, on the other hand, allows users to create their own lighting moods and then send those instructions to special lamps via a smartphone app. The lights can also be programmed to respond to specific events, such as by glowing a prescribed color when it is time to remove the roast from the oven.
For example, sensors could tell how many people are in a room and their location, and direct the proper amount of lighting to where it is needed. Medical patients prone to agitation could be calmed once facial recognition technology identifies them and changes the hue of an examining room to more calming tones. When older people enter a room, lighting intensity can be raised to compensate for their decreased ability to see.

“Today, lighting is becoming an appliance, like a blender,” said Mr. McGowan of the American Lighting Association. “I tell people when they move, they should take their LED bulbs with them.”
But synchronizing lighting to events is much more than a parlor trick. Philips has designed lighting systems that decrease growing times and increase yield for greenhouse vegetables and flowers, by using a light’s specific hues. In the Netherlands and Canada, among other places, tomato and vegetable growers are using Philips’s LEDs to improve bulk, increase fruit growth and reduce vegetable

Using Less Energy THE ENERGY-EFFICIENT BUILDING
M
odern houses use a lot of energy. We heat them, cool them, and light them inside and out. We use electrical appliances that allow us to cook faster, watch television and movies, listen to music, or explore the world by computer. A 2007 report showed that houses are the single largest user of energy worldwide, accounting for 25% of global demand. The United States leads the way, with its large houses, fondness for electrical appliances, and
development of subtropical and desert regions of the country. There are two main power sources for buildings. Electricity provides the power for lights, air-conditioning, and appliances, as well as heating many homes. Fossil fuels, either oil or natural gas, are often used in homes to make heat and hot water. In addition, in many locations around the world, the power used to generate electricity comes from fossil fuels such as coal. Either
directly or indirectly, then, the worldâ&#x20AC;&#x2122;s housing is consuming increasing amounts of energy derived from fossil fuels. As we know, those fuels pump carbon dioxide (CO2) and other greenhouse gases into the atmosphere. Thus buildings, especially houses, make a huge contribution to pollution and global warming. In the United States, residential and commercial buildings are responsible for 48% of
42 | Hong Kong Interntional Lighting Show 2014 Special | lightexpress
greenhouse gas emissions. Around the world, buildings account for somewhat less, about 30%. So, how can we make homes and buildings more energy efficient? There are many ways to reduce the amount of energy we use in our homes and buildings. We can turn off appliances and lights that are not in use. We can adjust the thermostat to use less heat in cold weather and less air-conditioning in hot weather. Energy-efficient products, including
furnaces, water heaters, refrigerators and other appliances, and even lightbulbs, can replace older, less efficient models. These steps help, but the bigger problem lies in the construction of buildings. If a building is not properly insulated in the exterior walls, the roof, and around pipes, it loses heat in cold weather and cool air in warm weather. Inefficient windows present similar problems. In fact, some estimates say that the world loses as much as two-thirds of the energy used for heating and cooling through poor insulation and leaky pipes. So, how do we build energyefficient buildings? Can existing houses and buildings be remodeled or retrofitted to save energy? For both, some of the options are simple and inexpensive. Others are complex and cost a lot to do. All, however, will reduce the amount of energy used. This cuts down on the amount of CO2 emissions, thus lessening the “carbon footprint” of each building or home. Increased energy efficiency also saves money, by lowering energy costs. Many countries offer financial incentives for such improvements. Heating and Cooling the Natural Way Before the development of modern heating and air-conditioning systems, people all over the world learned how to build and position their houses to take maximum advantage of heating by the Sun and the cooling effect of shade and breezes. This approach, known as passive heating and cooling, is having a resurgence. Many of these techniques have been around for ages. Today builders are starting to make use of these passive techniques to make homes more energy efficient. Passive heating makes use of the Sun through positioning of the house and use of building techniques and materials that absorb heat. Cultures as diverse as the ancient Greeks and Romans and the Pueblo Indians of the United States
knew how to use the Sun to warm their buildings this way. Cooling techniques use shade, breezes, and water to reduce the indoor temperature. Courtyards with fountains were common in the buildings of many warm countries, and ancient Persians and other peoples from the Middle East and northern Africa developed structures to cool their houses. In humid tropical regions, buildings had ventilation that allowed the warm air to move out with the breeze. Current passive techniques use the same ancient, local materials, such as stone, adobe, hay bales, and native wood. Local materials consume less energy in their manufacture and transportation. There is even a place for products of the modern world—for example, used tires, which absorb heat, or modern glass, which can retain heat from the Sun. Single-Family versus Multifamily Dwellings One way to increase energy efficiency is to minimize the surface area of the outside walls of a building relative to the amount of occupied space. It is these external walls, and the roof, through which heat is lost in winter and cool air escapes in summer. Multifamily apartment buildings offer some energy savings. There are fewer exterior walls per family, and floors above and below act as insulation.
number of interior walls and only one roof. That gives these types of buildings a lower potential for energy loss.
Most important, builders need to consider the interrelationships of all these elements. This is called the “whole-house approach.”
In some multifamily buildings, other factors may lessen the energy savings. Poorly constructed buildings may leak energy through windows, doors, and other gaps. There is often less control of heating for each dwelling, particularly in the largest buildings. Common areas such as hallways and lobbies require electricity, if not heat. In addition, large buildings need elevators to move people up and down the different floors.
Energy-efficient buildings may not look much different from the more traditionally built houses around them. However, some builders take a more radical approach. There are earth-sheltered houses, as well as ones that use materials such as old automobile tires or straw bales for walls. Renovation
The simplest way to make an energy-efficient building is to start fresh. New buildings can easily integrate passive heating and cooling techniques, materials that will help the building lose less energy, and energy-efficient products most appropriate for the climate. In addition, new construction can incorporate alternative energy-production options, such as solar panels or geothermal heat pumps, to decrease reliance on fossil fuels.
Realistically, most people can’t start new: We need to work with existing houses or buildings. There is still plenty that can be done, though. The starting point is an energy audit. This tells you how much energy a building uses, how much energy it loses, and what measures can be taken to make it more energy efficient. The energy audit checks for air leaks from and into the building and assesses the adequacy of its insulation. Heating and cooling equipment and electrical appliances can be replaced as well, to increase energy efficiency. Some techniques from new construction can also be applied.
Many countries, states, and cities have created “green” building standards for new construction. Standards vary depending on the hemisphere, climate, and materials available locally, because different climates require different design strategies and different materials.
For energy-efficient construction, we can learn from the past, we can learn from nature, and we can use the innovations of high technology. Let’s take a closer look at passive heating and cooling methods and how they can make a building more energy efficient.
New Construction
Multifamily houses come in many shapes and sizes. Large apartment buildings have many floors and multiple apartments on each floor. Smaller buildings may have six floors or fewer, with a few apartments per floor. Some buildings have a long rectangular shape, with many apartments on only two or three floors. Attached houses have exterior walls in front and back and common walls on either side. The one thing all these different types have in common is an increased lightexpress | Hong Kong Interntional Lighting Show 2014 Special | 43
Basking in a New Glow
I
f you haven’t noticed the virtual disappearance of old-school incandescent bulbs from retailers’ shelves, there’s good reason. With the federally mandated phaseout of traditional incandescent bulbs entering its final stage, manufacturers and retailers have done well to make the transition nearly invisible to consumers. As of last month, companies could no longer produce or import 40-watt and 60-watt bulbs, following similar restrictions on 75-watt and 100-watt
bulbs over the last two years. Some retailers still have enough 40s and 60s to last a few months, but you may struggle finding them amid the thicket of new lights labeled “40watt equivalent,” “60-watt equivalent” and the like. While those new bulbs will cost more up front, they can save money in the long term because they require less wattage to produce the same amount of light. That said, prices on newer bulbs are dropping quickly, even as design and performance improve. So if you
lack the energy or money to pursue a lighting overhaul in your home now, sit tight. Your patience — or wariness, or laziness — shall be rewarded. “We’re right at the beginning of this,” said Marc Voykovic, national light bulb merchant for Home Depot. “The technology is changing so rapidly you’ll continue to see improvements in bulbs as manufacturers are able to crack the code.” Not everyone can wait that long. My

home’s compact fluorescent lights, or CFLs, have grown so old and dim that I had little choice recently but to jump headlong into the morass of the current light bulb market. Thankfully I had help. In addition to calling Mr. Voykovic, I contacted Cecilia Dupire, principal of Cezign, an architectural and design firm, and Russell Leslie, a founder of the Lighting Research Center at Rensselaer Polytechnic Institute in Troy, N.Y. Lucas Borntreger, an electrician in Kansas City, Mo., also guided me through a fixture
replacement, but more on that later. My panelists said the biggest changes in the lighting market have come in the realm of the lightemitting diode, or LED. A few years ago, LEDs were billed as the next big thing, since they are extremely efficient and durable, to the tune of 25,000 hours of expected life. But the early bulbs came with “you can’t be serious” price tags (as in $40 for a 60-watt bulb) and gave off light that was as soft and warm as a granite quarry in January. Oh, and you couldn’t dim them. Over the last year, however, manufacturers rolled out dimmable LEDs for less than $10, with light that often rivals the old incandescents. Are they worth it? Probably. A 60-watt equivalent LED needs only
12 watts of power to produce the same light as a traditional incandescent. It consumes less than onethird as much energy as the lowestprice bulbs now manufactured: socalled halogen incandescents. According to the American Council for an Energy-Efficient Economy, based on conservative estimates, consumers who spend $10 on a 60-watt equivalent LED over a 60watt equivalent halogen incandescent will recoup the difference in about three and a half years, or less if you live in areas like New York, where utility rates are among the nation’s highest. At $5, you recoup your costs in less than 18 months.

section, and choose the “rooms” category.)
bulbs’ packaging, this was close to the “warm” end of the spectrum.
Some LEDs have more recently breached that $5 barrier, thanks to incentives from electric utilities provided for bulbs that carry the government’s Energy Star rating. Last week in Vermont and Pennsylvania, among other states, retailers carried 40-watt LED bulbs for roughly that price.
I expected identical light quality, or close to it, but at least three of the bulbs were noticeably cooler than the others. The warmest, to my eyes, was the Cree, which retails for just under $10. The Philips 11-watt LED bulb, the more expensive of the two Philips 60-watt equivalents, also offered a pleasing amount of warmth. The coolest was the Ikea Ledare E26, which sells for $7. Mr. Leslie said part of my issue could have been the white background of the light, and that one’s reaction to a certain bulb has much to do with its immediate surroundings. “If you buy an LED in the 2700 to 3000 Kelvin range with an Energy Star label from a manufacturer like Philips, Sylvania, G.E. and Cree, you’ll probably have a satisfactory product,” he said.
As newer LEDs gain Energy Star certification this year, $5 could become the new normal for 40-watt and 60-watt bulbs. The big question is whether you can find an LED that gives off your preferred light. I tried eight different 60-watt equivalent LEDs currently on the market from a range of manufacturers, and each of them was rated 2700 Kelvin. On the “Light Appearance” graphic included on the

panelists said, ask questions about light quality at the store, check the retailer’s return policies and save receipts. Ms. Dupire said LEDs have improved to the point that they represent 80 percent of the lights in her home. That includes traditional bulbs as well as smaller lights that complement lamps and other fixtures. “What’s wonderful about LEDs is that you can be both playful and functional with them,” she said. “You can do more imaginative stuff, like putting them underneath cabinets or inside closets because they don’t create as much heat.” Following her counsel, I tried the battery-operated G.E. Wireless LED Light in a closet that inexplicably lacked a socket, and they instantly turned the most irritating space in my house into something functional. Lamps and old fixtures can also get a playful upgrade with bulbs like the Philips Hue ($60, or $200 for a pack of three) or the Lumen TL800 ($70), which you control with a mobile device. (The Hue works with the iPhone, Androids and Kindles, while the Lumen works with iPhones and certain Android devices. The Hue also includes a BR30 option for recessed lighting fixtures.) Each bulb has a dedicated app that lets you change colors manually or according to predetermined settings, among other feats. This is especially useful if you have trouble waking up or falling asleep and would like ambient colors to help you in either regard. Continue reading the main storyContinue reading the main storyContinue reading the main story I liked both bulbs very much, but I favored the brightness and versatility of the Hue. The setup is slightly more complicated, however, since
you need to plug a base station into your wireless router. The Lumen works with a Bluetooth connection. Outside of LEDs, my panelists said, little has changed in the consumer light bulb market. Manufacturers have tweaked the efficiency of their halogen incandescents to meet the new federal standards, and manufacturers say they expect these bulbs to dominate the market while the LEDs edge their way into the mainstream. Manufacturers said CFL technology has stagnated, and my panelists echoed that sentiment. But I found one exception worth noting. The Plumen 001 ($30) and the Baby Plumen 001 ($29) feature a cool variation of the traditional “twisty” CFL design. The company also sells single bulbs packaged with a sleek, matching hanging fixture for $65.
out how to install it without electrocuting myself or creating a fire hazard in my house. Pixi offers a good how-to video, but it didn’t account for the wiring configuration in my basement. Rather than call an electrician for a visit, I tried a new online service from Google, called Helpouts, in which contractors and other professionals offer advice through video chats. The professionals are reviewed by Google, but as with anyone you might contract for home-repair services, would-be customers should check out the professional’s credentials before going forward. Mr. Borntreger, for instance, is a licensed master electrician with extensive experience. For $15 he
The light is warm and pleasant by considered installing a set, but the idea of cutting holes in my ceiling and wiring new fixtures was a bit too ambitious. At the same time, I’ve been on the lookout for an electrical project a little more challenging than rewiring a lamp, but preferably in a low-stakes setting. It boasts square, recessed fixtures that were installed 40 years ago, and which we, in recent years, lit with junky CFLs. Sometime last year two of the fixtures simply stopped working. It was almost an improvement. I heard about a new LED product, the Pixi FlatLight luminaire, that’s advertised as an ideal replacement for such Nixon-era fixtures. The Pixi is less than an inch thick — including the (nonreplaceable) light itself — and comes in three sizes. I chose the 1-foot square size ($70 each), as it is nearly identical to our existing fixtures. My only remaining task was to figure

offers 30 minutes of advice. After two calls and about an hour of work, I installed four fixtures, and did it with the confidence that I hadn’t ruined the job. Without Mr. Borntreger I would have known to shut off the light circuit at the breaker, and test the fixture with a voltage meter for good measure. But had I not called on him, I most likely would not have looked deeply enough into the junction box to see an additional set of wires that were important. My next time out, I’ll have the same respect for electrical work but much less worry. Of course, I’ll probably rely again on Mr. Borntreger, or someone like him, as my phone-afriend.
U.S. DOE will announce Sharp developed a smaller the LED and OLED research and brighter backlight LED fund plans of 2015 U.S. Department of Energy (DOE) will announce the Small Business Innovation Research Program (SBIR) and Small Business Technology Transfer (STTR) program of formal financing plan of 2015 fiscal year on August 11, 2014. The agency said that the materials research center in the field of LED and OLED are within the scope of the agency’s consideration. Before the formal announcement, the DOE will hold a webinar for who intends to submit application, and will present an overview for the technical fields which included in the scope of the DOE’s consideration on July 22. The second webinar will be held to review the application process on August 15. Financing application letter of intent must be submitted on or before September 2, formal application also will end on October 14. U.S. Department of Energy is expected to announce the results in January next year, while grants will also begin issuing in February. In addition, U.S. Department of Energy scheduled the date of the next Solid State Lighting (SSL) market development seminars from November 11 to 13 2014, and the agency will announce location soon.
Sharp announced the development of a wide color gamut, high brightness and small size LED, it suitable for small and medium size LCD backlight. Sharp will delivery samples on August 6, 2014, and put into mass production on September 2014. The current sample price is 40 yen. The new LED named GM4BN6F3S0A, can achieve the total luminous flux of 8.3 lm, color gamut achieves 90% of NTSC standard. The brightness of the new sample is 12% higher than the previous sample (GM4BN6B3S0A, 7.4 lumens). The brightness increasing due to improve luminous efficiency for blue LED, redesign package and adjust the red, green fluorescent material combinations proportions. In addition, by improving packaging technology, Sharp Corporation also reduced product size, it about 30% smaller the previous product. LED package width is reduced from the original 3.8 mm to 3 mm, but did not change the power consumption. The company said the benefits of smaller size is able to increase the number of LED that installed in LCD screen, and improve the brightness of small and medium-size LCD panel (mainly for tablets, laptops and other devices). GE has announced the licensing to Sharp Corporation, allows Sharp to use red fluorescent and widening LCD display color gamut technology.
UK Department of Energy plans to fund $34.2 million for upgrading LED lighting According to UK Department of Energy’s power consumption reduction plan, British families may pay millions of pounds to provide free LED lighting for supermarkets and airports. British Energy Minister Ed Davey recently announced the implementation of 20 million pounds ($ 34.2 million) taxpayer cash tracking program, aim to provide funding for businesses to upgrade energy efficiency including replacing traditional lighting by LED light bulbs, and these funds will be used for those who do not advance funds. Davey said that companies can compete for funds by reverse auction, and complete the entire installation through full or part of the subsidies, which will help to generate cheaper energy bills. There are about 300 organizations, including hospitals, airports, supermarkets, have shown interest in this pilot, the UK Department of Energy and Climate Change (DECC) said. The purpose of the program is to reduce the national electricity demand, mitigate blackout risk, and avoid building more power plants. If the program successful, it will continue to provide the cash. 48 | Hong Kong Interntional Lighting Show 2014 Special | lightexpress
RUSSIA ENCOURAGES CHINESE COMPANIES TO SET UP LED FACTORIES IN RUSSIA Gruzdev Alexey, the representative of Trade Representation of the Russian Federation in the People’s Republic of China, said in Russian and the CIS countries’ Lighting Market Analysis and Channel Strategy Conference that “In lighting products, China has always been the largest supplier of Russia.” Along with Russian accession to WTO, prohibition of sale incandescent bulb, Winter Olympics in Sochi this year and World Cup in 2018, Russia has great demand on LED lighting. Russia welcomes the strength Chinese enterprises to participate the LED renovation projects for public institutions of Russia and CIS countries, large industrial and mining enterprises, sports stadiums and others. According to Gruzdev Alexey’s introduction, Russian LED industry was developed rapidly last year, the growth rate is 250%, and LED lighting accounted for 10% of market share. Data shows that the Russian LED bulb sales in 2013 are 1 billion units, with total sales of 40 billion rubles (about 1.11 billion US dollars). As the Russian government introduced a series of measures to promote energy-saving light sources, it is expected that Russia LED lighting market share will increase to 35% of whole lighting industry in 2016. Last year, Chinese LED products export to Russia and CIS countries is $ 800 million, which Russia accounted for 75.74%. China LED products accounted for more than 40% of Russian market. “We strongly encourage Chinese advanced enterprises to invest in Russia, there many Chinese enterprises may worry about the problem of investment environment, tax, legal protection and other issues, the Russian government has done a lot of work in the past few years, and have improved greatly in company registration, investment, banking services, tariffs and other aspects.” Gruzdev Alexey said. “In my opinion, the preferential policies offered in Russia are more favorable than Chinese implementing policies.” Gruzdev Alexey believes that since China began LED very early, so the preferential policies have been canceled in a lot of economic zones, while Russia is now actively promoting these policies. He said that if set up factories and registered enterprises in Russia, besides providing favorable conditions, the Government will allocate some financial support, and different regions have different policies. “For example, including at least five years of free land usage, general profit tax is 20%, in order to encourage Chinese companies to set up factories in Russia, this ratio may be adjusted. Additionally, the local government is also with positive attitude on simplifying administration, shortening the approval process, reducing approval procedures, etc.” 50 | Hong Kong Interntional Lighting Show 2014 Special | lightexpress

Philips gives workers smartphone control of office lighting with groundbreaking connected lighting system TEMPLATE OFFICE OF THE FUTURE FOR GREATER COMFORT, PRODUCTIVITY AND BUILDING EFFICIENCY
W
orkers able to personalize lighting and temperature via smartphone app
Connected LED lighting powered over Ethernet provides anonymous occupancy and climate data for more efficient facility management Royal Philips (NYSE: PHG, AEX: PHIA), the global leader in lighting, announced a breakthrough connected office lighting system that delivers extraordinary value to facility managers, office workers, and building owners. The groundbreaking system uses Power-over-Ethernet (PoE) to connect office lighting fixtures to a building’s IT network. The lighting system acts as an information pathway, enabling workers to control and access other building services via their smartphones, allowing them to enjoy greater visual comfort and productivity. The office lighting fixtures, when outfitted with sensors, are able to capture anonymous data on room occupancy, temperature and humidity. They connect to the IT
network and interface with other building systems such as heating, ventilation and IT services. This benefits the facility manager who has a single system showing real time and historical views of building utilization. For example, he or she could see that on a Friday afternoon a particular floor is not used and adjust the temperature, lighting, and cleaning roster accordingly. Having an integrated view of a building’s occupancy patterns and energy usage provides for more informed decision making with unprecedented levels of energy and operational efficiency. Smartphone control The Philips system allows office workers to control the lighting in open plan offices as well as temperature in meeting rooms, to suit their individual preferences. Their smartphones will detect their location from overhead lighting fixtures via an app. “The LED lighting alone is 80% more efficient than conventional lighting. Personal control of the lighting by employees actually increases efficiency as general lighting levels can be kept lower.’’ said Jeff Cassis from Philips Lighting. “The potential savings on a building’s operational costs will be significant, given that heating, cooling and lighting
together account for 70% of a building’s energy usage.¹” The fixtures, outfitted with wireless communications devices, form a dense indoor positioning grid, like an indoor GPS, that support a range of location-based services, such as wayfinding. Through a smartphone app, the system could also provide workers with useful information such as the nearest empty meeting room. Delighting building owners and facility managers For building owners, the system offers new value that goes beyond energy efficiency and cost savings. Advanced capabilities such as indoor positioning combine with the intelligent system to enable comfort, personalization, and safety, increasing the total value of a building and making it more attractive to tenants. Standards-based PoE-enabled fixtures also deliver significant cost savings on lighting installation. As these fixtures receive both data and power over a single Ethernet connection, there is no need for expensive electrical wiring, reducing installation costs by up to 50%. The connected lighting system installed at ‘The Edge’, a cuttingedge office building being developed by OVG Real Estate for

Deloitte in Amsterdam, is the first of its kind. As pioneers in workplace innovation, Deloitte and OVG Real Estate chose Philips and its connected lighting system to help the building meets the highest standards of sustainability (certified BREEAM² - Outstanding). “Innovation is our top priority at Deloitte and we want to create a more intuitive, comfortable and productive environment for our staff. We also see our office raising the bar in data analytics with completely new insights in the use of office space, leading the way for offices to reduce the CO2 footprint of buildings and create a more sustainable world.” said Erik Ubels, Chief Information Officer at Deloitte in the Netherlands. Coen van Oostrom, Founder & CEO from OVG said : "Our innovative partnership with Philips and Deloitte/ AKD for this project at ‘The Edge’ will result in a new blueprint of sustainable development for the building industry. We are proud to implement and co-create this building management system together with these leading companies to drive value for building owners, tenants and office workers. This project fits our ambition to stay in the driver's seat for sustainable office innovation."
An LED Bulb Is Both Dimmable and Affordable THE PHILIPS SLIMSTYLE LED LAMP
H
ere’s a bulb you might think about licking rather than lighting. Philips’s cut the weight of its new SlimStyle lamp down to about three ounces by eliminating the heat sink found in most other LED lamps.
The bulb looks unlike any that has come before — more like a lollipop than a lamp. It has the ability to dim and gets only warm to the touch even after a few hours of illumination, eliminating two shortcomings of LED bulbs. It’s priced under $10 at Home Depot. This 60-watt equivalent uses 10.5 watts of energy. The actual light-emitting diodes ring the lamp’s circumference, creating light in all directions. In a test, the SlimStyle created a dimmable, warm glow that was virtually indistinguishable in quality to a standard incandescent. The bulb is now available on the Home Depot website and will be available in its stores in March. Like other LEDs, the SlimStyle will meet Energy Star requirements and last for 25,000 hours, or about 20 years of average burning.
