The anniversary is a good time to take a closer look at the results and lessons learned, with more than 80% of the LED fixtures planned for phase one deployed. The lessons learned are based on a presentation delivered by Ed Ebrahimian, Director, Los Angeles Bureau of LED high bay light, to the IES Street and Area Lighting Conference convened in Miami in September 2012.
Noribachi replaced the fluorescents with the popular LOWBAY vapor proof fixture. The new lights use about half of the energy while emitting a much brighter, cleaner light. Inside the parking structure this translates into an increased feeling of security and heightened color perception, making it easier for drivers to locate their vehicles.
Lining Manhattan Beach Boulevard, the City’s main thoroughfare, are historic lantern fixtures that also required an LED upgrade. This application demanded a retrofit of the lantern fixture to maintain the original aesthetics. In order to achieve this Noribachi created a custom LED solution designed to easily sit in the existing housing. Noribachi’s experience in diffusion allowed engineers to direct the light straight down inside of the existing lens, creating a glowing effect and shielding the individual diodes from view. Noribachi also used LEDs with a warm white color temperature to match the historic ambiance.
The showroom has been carried out in collaboration with the Austrian practice Innocad Architektur ZT and the UK’s Space Group Architects. The luminaires on show include XAL’s Helios which is shortlisted in the interior category for the 2013 Lighting Design Awards.

who rated purchase price as the most important factor
Many consumers will make their first LED lamp purchases in the next few years, and the market is entering a critical window for making a positive impact on consumers’ first impressions of LED technology,” said Eric Kim, CEO of Soraa. “However, for LED high bay light to achieve significant market share, consumers must be confident that these lamps can give them the light quality they need and want. With the emergence of next generation LED technology, these performance benchmarks have now been reached.”
McKinsey’s 2011 Lighting the Way report suggests that consumer and commercial lighting purchase decisions are driven as much by light quality, as they are by the cost of the light bulb. Twenty percent of the residential respondents in the McKinsey report rated light quality as the most important decision criterion for lamp installation – which is on par with the 22 percent who rated purchase price as the most important factor. In all other market segments, light quality was by far the most important criterion.
“The slow market adoption of CFLs over the last 20 years demonstrates that simply because a product produces enough light, saves energy and is cost-effective, broad market adoption of that technology is not ensured. To persuade consumers to purchase LEDs instead of incandescent lamps, LED lamps must be seen as high-quality products worth the initial higher price differential. Therefore, LED lamps must closely replicate the color rendering and color appearance of the incandescent and halogen lamps that they replace,” said Carlos Alonso-Niemeyer, Energy Efficiency Program Manager of NSTAR a Northeast Utilities Company.
EPA pointed out in their latest draft lamp specification that lack of LED lamp color quality is a potential barrier to broader consumer adoption of energy efficient lighting. However, EPA went on to say that it will continue to monitor the market and explore opportunities for improving color quality and consistency of lamps in the future. Given the critical importance of this issue to increased adoption of LED lighting, groups told EPA that the time to address higher color rendering is now.
“Designers should have the flexibility to select the appropriate source for their applications and end users should have their right to purchase high color rendering or full spectrum lamps for their spaces,” said Chip Israel, President of the Lighting Design Alliance.

policy effects can create great opportunities as well as great challenges
The future trend of lighting energy lies in LED combined with solar energy. Except for common household lighting, LEDs are being applied in many different areas, such as automobile headlights and daytime running lights. SeekIC will make further developments and increase market shares in the LED field. For SeekIC and LED manufacturers, policy effects can create great opportunities as well as great challenges.
Toshiba Corporation will begin mass production of white LEDs on 200mm silicon wafers this month based on technology that it licensed and developed with Californian firm Bridgelux.Deployment of Toshiba and Bridgelux’s gallium nitride-on-silicon (GaN-on-Si) technology to produce LED chips, has allowed Toshiba to replace sapphire substrates and produce the chips on a more cost-competitive silicon substrate.
Production of LED chips is typically done on two to four-inch wafers with an expensive sapphire substrate but Toshiba and Bridgelux have developed a process for manufacturing gallium nitride LEDs on 200mm silicon wafers, which Toshiba has brought to its new production line at Kaga Toshiba Electronics Corporation, a discrete products factory in northern Japan.

The same time improve electrical efficiency by alleviating problems of light trapped or lost in an LED chip
Another core technology in which Epistar excels is bonding technology that provides for flexibility in epi structure substrate selection. Epistar’s RD team has developed various bonding techniques with metal, glue, and dielectric materials so that the epi structure is not limited by its growth substrate anymore. Taking GaN-on-Si as an example, after nitride is grown on Si substrate, the epi can be transferred to a transparent or reflective carrier by bonding technology to avoid the light from being absorbed by opaque Si. In other applications, multiple LED structures with different light color can be bonded to one common substrate. With different bonding materials, LED can be disposed on different carriers depending on the application. For example, a widely-adopted low temperature metal bonding process provides robust mechanical support with optional reflector for light extraction enhancement, which makes a vertical blue LED possible at lower cost. Epistar’s innovative glue or dielectric bonding provides a transparent interface that provides the LED with the advantages of having stronger support and transparency, which is expected to be particularly useful in general lighting and LED display applications. Epistar has successfully obtained patents in this technology around the world, including in China, Japan, Korea, Taiwan, and the United States.
For applications requiring high power, a larger size chip is normally preferred because it endures high current injection with high power efficiency. Epistar has acquired a portfolio of patents from a Swiss company directed to technology including the design of extension electrodes that can avoid the high cost associated with the process and at the same time improve electrical efficiency by alleviating problems of light trapped or lost in an LED chip.
As the first company to commercialize high-voltage chips (HV), Epistar has also developed several arrangements of multiple cells/junctions on one common substrate that can be driven by high voltage. With its delicate interconnection design, HV chips have excellent electrical properties and flexibility for diversified lighting applications. In addition to such unique structure, Epistar is known as the only chip maker that can provide full-spectrum products. As a result, Epistar can help customers by using its excellent red and blue chips with one or more cells/junctions for warm white applications. Design patents and utility patents related to this technology have been granted to Epistar in countries around the world including China, Japan, Korea, Taiwan, and the United States.
Epistar’s RD team is full of energy and has a vision for the future. There are already several ready-to-go technologies in the patent portfolio that can embrace the LED lighting era to come. One representative work is to connect chips on one transparent base to form a filament-like structure for retrofit light bulbs or lamps. In addition, Epistar also obtained exclusive rights in remote phosphor field that contains an optical device in-between a wavelength converting device and an illumination source. With these patented technologies, Epistar can work with its customers to develop more competitive products and speed up the adoption of LEDs in lighting.

The opportunity to learn more about LED lighting technology for the home
Using just 11 watts of power while putting out over 830 lumens, the latest generation of Philips’ 60 watt A-19 LED bulb uses 10 percent less energy than its 12.5 watt predecessor, while increasing brightness by nearly 5 percent. The new lamp has an innovative new design that takes advantage of Philips AirFlux technology, a new airflow cooling system that eliminates the traditional distracting heat sink fins needed for thermal management of LED bulbs. Philips will be unveiling the new bulb at The Home Depot store on 59th Street in Manhattan on December 4th – 5th and at the 23rd Street store on December 5th-6th, offering consumers a $5 savings and the opportunity to learn more about LED lighting technology for the home.
Designed to exceed Energy Star specifications, the bulb will reduce energy consumption by 85 percent, last 25 times longer and save an estimated $134.00 in electricity costs during its lifespan, as compared to the traditional 60-watt incandescent. This LED bulb will also offer consumers two different color temperatures, Soft White and Daylight, while the new sleek white shape makes it ideal for open fixtures and sheer shades.
The new Philips A-19 LED bulb offers enhanced dimming capabilities, dimming down to 2 percent of power, while working with a broader range of dimmers. This further simplifies use and allows consumers to enjoy an effective, low energy solution for lighting in the home. For business users, particularly those within the hospitality sector, the new lamp will provide instant plug-in savings, through reduced energy and maintenance costs, in comparison with traditional bulbs.
“We continue to push the boundaries of LED technology to improve the performance of our products, enhancing their light quality, while improving their energy-efficiency,” said Ed Crawford, general manager of Philips Lighting. “This latest generation of our LED bulb eliminates the tell-tale heat syncs of LED technology enabling a classic design, while reducing energy consumption by 10 percent offering more light output.”

Rookie USA chose LED lighting for its first store for many reasons
Rookie USA chose LED lighting for its first store for many reasons: Long-term cost efficiency, less frequent lamp replacement, less heat emission resulting in less HVAC expenditure, and the design. “The design of the luminaires for general lighting was very important to us, because the space is an open plan. Additionally, the luminaries had to be functional but also unique. Phoster Industries was the vendor that could provide everything we were looking for,” Rookie explained.
Thanks to its tremendous energy efficiency over standard incandescent lamps, the LED solution will help to reduce annual energy costs by up to 85 percent. The Phoster lamps have a rated lamp life of about 50,000 hours, which almost makes lamp replacement unnecessary, another factor contributing to cutting costs. “By electing to use LEDs for the lighting at its new store, Rookie USA has made a pioneering move in terms of the many advantages of these tiny diodes,” says Douglas Mendelman, Director of Business Development at Phoster Industries. “The combination of the Golden Dragon Plus LED high bay light from Osram and our luminaire systems creates a pleasant atmosphere inside the new store, makes products look their best and lowers energy and maintenace costs at the same time.” Osram Opto Semiconductors and Phoster Industries have already collaborated successfully in the field of store lighting. The joint lighting solution therefore was Rookie USA’s first choice when it came to putting its products in the best possible light.
As part of a pilot study by the Public Works Commission, the city-owned utility plans to convert about 300 conventional streetlights to LED bulbs, which last three times as long and use about half the electricity.
The LED, or light-emitting diode, technology has become increasingly common in everything from traffic signals to flat-screen TVs. Big cities such as Los Angeles and Seattle are aggressively switching their public lighting over to LED fixtures to brighten streets and save money in the long run.

the best effect for the least energy and installation cost
Marl can accept a CAD drawing of the internal or external area to be lit, or a simple dimensional drawing, and will use 3D modelling software to choose the most suitable energy efficient LED lighting products, and place them to achieve the desired effect. In consequence, the right light level is available in each location, but the minimum of light leaks upwards or sideways into areas where it isn’t needed. Marl will then implement the scheme using standard or custom products that it manufactures based on leading edge LED lighting technology.
According to Adrian Rawlinson, Managing Director of Marl International, “Lighting can make or break the appearance of a building – making it welcoming, attractive and safe or conversely, threatening, unattractive and hazardous. LED lighting is energy efficient and highly directional – minimising the issue of wasted light. We have exact models of the light output of the products that we supply. Using the design tools we have, we can combine our models with customers’ designs and statements of requirements to come up with a lighting scheme that produces the best effect for the least energy and installation cost.”
Marl has successfully designed and implemented lighting schemes for a wide range of projects including, schools, offices, car parks, attractions and factories. Marl’s lighting solutions are based on technologies from world leaders like Citizen, Lighting Science and Bivar, which it integrates into finished and ready to wire luminaires that can be driven from the UK mains and meet the UK electrical standards and specifications. These products are designed, manufactured and tested under one roof at Marl’s manufacturing facility in Ulverston, England.
Vietnamese scientists are trying to create LED lamp products which have the light spectrum suitable with every kind of plant, which can help save electricity, churn out clean and off-season products.According to Dr Phan Hong Khoi, Managing Director of the high-efficiency public lighting project in Vietnam, LED is a special type of semiconductor diode which can generate a narrow spectrum, discrete light when excited. LED lamps can create different colors, depending on the semiconductor materials used and operating conditions.

the Green Proving Ground program to evaluate sustainable building technologies
According to the GSA, energy efficiency is becoming a way of life, not only to cut costs at more than 9,600 assets that it owns or rents, but also to meet the 2007 federal mandate that government buildings slash energy consumption 30 percent by 2015.
To meet those goals, and to push the whole market forward, it launched the Green Proving Ground program to evaluate sustainable building technologies. Based on performance, the GSA can then recommend technologies to its portfolio.
The GSA has already published findings on occupant-responsive fluorescent lighting, but now it has turned its attention to LEDs and controls.
As part of the Recovery Act, the GSA had more than 200 projects of lighting retrofits, but few were LEDs. “The Green Proving Ground GPG program is looking at the next generation of products that are targeting general office lighting, which is the great frontier,” said Kevin Powell, program manager for Green Proving Ground. The frontier has certainly moved to LEDs, which have come down significantly in price.

No judge has been assigned to this case as of yet
The company is claiming Apple's products utilizing pulse-width modulation signals to drive LED, include the iPad 3 tablet device and MacBook Pro notebook. According to LED, the facts learned in the discovery process show that the infringement of LED Tech's patents is or has been willful.The case was filed in the United States Delaware District. No judge has been assigned to this case as of yet.
Lighting is reported to utilize its Zalaegerszeg based factory in Hungary to manufacture LED lamps by the end of 2012. It’s said that GE Lighting has greatly reduced its lamps business in Hungary since EU gradually phases out less efficient traditional light bulb.
LED products are growing exponentially in 2012 and particularly for “Curing related applications”. Traditionally, mercury lamps are used for curing purposes but with short lifespan and lengthy warm-up time. Besides poor efficiency, other shortcomings include; massive heat generation, radiation and ozone emission (both damaging to materials exposed); huge power consumption, and contains hazardous mercury.
It is to launch an LED development laboratory, reorganizing engineers from other Hungarian operations, while Oracle will set up an 'Applications Lab' in Hungary, increasing the current number of employees, which is 200, by 10%, and is looking to increase this.

the change in purchasing behaviour that will result from familiar incandescent bulbs disappearing from the marketplace
Although an integrated communications strategy will be required to educate people about the impressive energy and money saving benefits of solid state technology, the appropriate standards and regulations must also be introduced to ensure that information is accurate and easily available. An issue that is ripe for reassessment is the set of standards by which lighting technologies are measured. These systems have often been unrepresentative of technology quality and put LED assets at a disadvantage; an obvious example being the LED high bay light practice of measuring the light quality at the point at which a bulb is first switched on rather than over its lifespan, thereby failing to reflect the long life and enduring quality of LED technology. The purpose of standards should be to evaluate technologies and protect consumers – and they must do so adequately and fairly.
It is not enough for such standards to exist; they must be accessible and present in the minds of consumers and other purchasers such as procurement professionals. The easiest way to achieve this would be to include the relevant information on packaging, which would facilitate like-for-like comparisons at point of purchase and allow price to be weighed against factors such as efficiency. After all, consumers will hesitate to pay more for a technology if its advantages are not immediately apparent and, unsurprisingly, 23% of customers surveyed by Consumer Reports cited cost as a key reason for avoiding LEDs.
Simply waiting for LEDs to reduce in price enough to no longer be considered an “investment” purchase is not an option for two reasons. First, becoming engaged in a battle to artificially drive down costs puts at risk the very thing that makes LEDs stand out in the lighting market - the superiority of their technology. Second, it is vital that we do not fail to capitalise on the change in purchasing LED linear high bay light behaviour that will result from familiar incandescent bulbs disappearing from the marketplace.
LED technology offers coherent efficiency, environmental and financial advantages across the board. It is crucial that we as an industry ensure these benefits do not stay in the shadows but are brought into the light for all to see.

they will be left without a light source during the long lunar night
The future of further human deep space exploration is dependent on the development of many new systems and technologies. And researchers have considered that nuclear-powered state of the art LED technology is “what will drive (the) photosynthesis so necessary to provide both food and oxygen for future lunar colonists.”
Future long-term lunar residents will need to grow their food either in sub-lunar lava tubes or in greenhouses shielded with several meters of lunar surface regolith. With no atmosphere, the moon is regularly exposed to lethal doses of cosmic rays, solar coronal mass ejections and x-flares, not to mention micro-meteorites that would be enough to wreck anyone’s corn.”
“Although during the two weeks that make up the long lunar day astronauts might be able to funnel refracted sunlight into covered greenhouses or subsurface lava tunnels, they will be left without a light source during the long lunar night.”
“Current solar-powered battery storage technology isn’t adequate to sustain artificial light sources for two weeks at the time. Thus, the most practical solution is simply to use some sort of Radioisotope Thermoelectric Generator (RTG), not unlike the one powering the current Mars Science lab, to power the LEDs that will spur photosynthesis in lunar greenhouses.”

the government is paving the way to announce newly established national standards
The GE Evolve LED Garage fixture uses cutting-edge technology, featuring an advanced LED low glare optical system coupled with a unique thermal management system to ensure long life and excellent photometric performance—that is, casting light where it’s needed without trespassing into areas it’s not.
After retrofitting 1.25 million square feet of parking garage space with 1,500 GE Evolve? LED Garage fixtures, Spectrum Health, one of Michigan’s largest not-for-profit health systems located in Grand Rapids, will save $170,000 annually in combined energy and maintenance expenses.
The upgrade has saved the facility nearly $170,000 annually in combined energy and maintenance expenses, helping to further fulfill Spectrum’s environmental efforts. By replacing older 175-watt high-pressure sodium (HPS) fixtures, with GE’s 60-watt Evolve LED lights, the hospital will see a 67 percent energy reduction, yielding 1.6 million kilowatt hours (kWh) of energy savings annually.
According to Taiwan state-funded institute, the government is paving the way to announce newly established national standards for the smart lighting industry on Aug. 14, to expand demand and worldwide business opportunities.

the size of the effect depends on the color
With Light pollution has become a growing problem, and skylines continue to grow, the night sky becomes dimmer and dimmer. However, researchers estimate that that night time sky could become bluer thanks to LED lighting.
Christopher Kyba, physicist at the Freie Universität and lead author of the study, said in a press release that , “The current worldwide trend of replacing gas discharge lamps with solid state lighting, such as LEDs, will affect the radiance and spectrum of urban skyglow.”
Franz Hölker, ecologist at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries and study author, said for nearly all of evolutionary history, clouds have made the night sky darker, just like what we witness during the day time.
However, in areas with artificial light, the effect of clouds is now reversed, and the size of the effect depends on the color. The team found that in Berlin, the blue portion of skyglow is 7 times more radiant on cloudy nights than on clear nights, and 18 times more for the red part.
