tests are under way of LED lights in the parking

Some companies and a growing number of cities have started adding LEDs incrementally. For such users, the savings LEDs provide on energy bills, bulb-replacement and labor costs can often cover the higher up-front cost in about a year, industry experts say.Raleigh,recently installed led high bay light in parking decks and other outdoor spaces. Dan Howe, assistant city manager, estimates that in one underground parking deck the change will save the city more than $700,000 in energy and maintenance costs over the 15-year lifetime of the LED products.After tests at two of its stores in Texas and Colorado, has decided to use LEDs in the freezers and refrigerators at all 4,200 of its stores in the U.S. A company spokesperson adds that tests are under way of LED lights in the parking lot of a Wal-Mart store in Arkansas.

For now, price remains the biggest obstacle, especially for residential use. But there are signs that this is changing as well. Consider "down lights," the kind of directional, recessed lighting that is common in many homes and offices. LEDs are well-suited for this kind of lighting because they typically provide directional light. But despite their suitability for this purpose, Sloan Ritchie, a sustainable-home builder in Seattle, says he isn't yet installing LED down lights because they're too expensive: about $80 each, compared with $15 for an incandescent and $35 for a fluorescent. Even though LEDs offer savings in the long run -- and use less energy -- consumers still are reluctant to pay more up front. However, with LED prices falling about 25% a year, Mr. Ritchie says he may begin using them next year.

According to the Energy Department's Mr. Brodrick, some manufacturers already are test-marketing products in stores of Home Depot Inc., the big home-improvement retailer. Meanwhile, for the LED market itself to light up. For one, as often happens with new technology, the quality of led flood light products currently on the market is uneven. Of 140 LED products in stores and tested by the U.S. Energy Department, more than half were considered poor quality. People get kind of interested.

somebody has made some very bad decisions

EPA seeks to ensure that qualified fixtures meet consumer expectations for light output. Consumer preference for light output varies widely, and the same is true for fixture design intent. Therefore it is impractical to prescribe lumen values for various residential lighting fixture applications. This consumer awareness requirement is intended to help consumers understand the limitations of LED light engines producing less than 800 lumens (equivalent to 60 watts incandescent)." No reason to accept the lighting industry and market consensus that consumers may actually have an interest in the amount of led high bay light that actually comes out of the fixture, and certainly, what does the lighting industry know about an acceptable level of brightness for different types of residential fixtures? And there doesn't seem to be any reason to recognize the directional nature of LED lighting, or that it is inherently different from any of the predecessor illumination sources. They are probably great people over there at the EPA, but somebody has made some very bad decisions.

The EPA has no significant reason to be involved with the Energy Star program at all, they know it, they lost any mandate for involvement with SSL and this is a desperate "land grab" to try and retain a stake in something they have no business in. Frankly, justifying EPA co-control of Energy Star on the basis that lower energy consumption reduces energy-production related pollution is analogous to the Treasury Department claiming a stake in Energy Star because an emphasis on energy efficient products can have an effect on the distribution of tax revenues in various manufacturing sectors. Their claim to co-control is more historical, since the EPA generated the Energy Star moniker in the mid-1990s to apply to computers that had a sleep mode capability. The DOE had created an "Energy Saver" label with a full range of products, but clearly someone in the EPA had some pull at the time and while the DOE and EPA programs were merged, the Energy Star label won out and the EPA kept its stake in the energy efficiency programs. Once again, we prove that when something is given to, or taken by, a government agency, they are generally loathe to give it up later on.

If you are a luminaire manufacturer, ignore the technical addendum to the RLF Energy Star spec; If you are a specifier, don't depend on our opinion. Contact the EPA yourself and have them explain to you how the technical addendum to section 4.2 of the RLF will assure you of high quality luminaires that meet customer expectations, and how it will aid adoption of SSL technology rather than harm it.If the audience at large becomes aware of an LED-based luminaire or fixture provider that applies the Energy Star mark based on qualification under RLF Version 4.2, forward them to us here at Solid State Lighting Design and we'll post a list of those manufacturers on a special page dedicated to, "Products that may have been qualified to a less rigid led flood light specification that could compromise the consumer perception of, and satisfaction with the LED-based lighting product that results... We recommend that you contact the manufacturer for luminaire-level test result data before making any purchase decision regarding this product. Pass the "permalink" to this editorial along to anyone and everyone that you think might have an stake in the success of solid state lighting. Let's get some buzz going before this nonsense gets out of hand and inferior products hurt us all.

the chips are based on led high bay light technology

Opto Semiconductors is more compact and efficient than ever before and is designed for integration into ultra-miniature pico projection applications where space is at a premium. This compact led flood light module measures just 5.8 x 4.7 x 1.5 mm and, in contrast to its predecessor, does not require additional connectors on board for electrical interface. Thanks to SMT (surface mount technology), this new version of the OSTAR? Projection LED is now suitable for standard soldering processes.

Projection SMT LED is ideal for applications such as the pico projectors now being integrated into cell phone and other mobile appliances. Pico projectors can be either integrated directly into the phone housing or attached to the phone as an accessory.An embedded cell phone pico projector typically measures 1.5 cm x 3.0 cm; in this configuration,Projection SMT LED provides a system brightness of 10 screen lumens (lm) with a power consumption of 1 W. The larger accessory versions of pico projectors, which measure 7.5 cm x 7.5 cm, can be operated with a higher wattage and can achieve brightness values of more than 15 lm.

Personal mobile device projection is the next wave of technology that will be integrated into today’s function-rich cell phones,” said Mike Godwin,Projection SMT LED shows the versatility of OSRAM LEDs in next-generation consumer applications, making it possible to achieve high-performance operation from micro-sized packages.Projection SMT LED module contains four 1 mm2 RGB chips – two green, one red and one blue. As an alternative to this RGB version, the OSTAR? Projection SMT LED is also available with four monochrome ultra-white, red, green or blue chips. Depending on the color, the chips are based on led high bay light technology and are designed for optimum efficiency. The chips are located together with ESD protection diodes on a ceramic carrier with a monolithic glass window to provide cover and protection. Besides pico projectors, the compact but powerful OSTAR? Projection SMT LED also lends itself to other applications such as specialty and fiber lighting.

the energy that was being consumed by the incandescent light

This hardy bulb is perfect in any situation that allows for 26mm Edison screw base attachments. Applications perfect for this bulb include decorative chandelier lighting. These high quality Flame Tip Chandelier LED bulbs can directly replace standard-base incandescent bulbs, allowing a long lifespan of up to 50,000 hours. Furthermore, since these bulbs are made with LEDs, they are resistant to shock and vibrations, frequent switching - they will not burn out from being switched on and off.

Sunovia Energy Technologies, Inc. is pleased to announce that it has completed the lighting renovation at the Oaks Country Club tennis facility in Sarasota, Fla. The renovation required that Sunovia replace the existing incandescent light fixtures at the facility with Sunovia's proprietary LED light fixtures, sold under the brand name EvoLucia(TM). As a result of the renovation, the Oaks facility is now using less than 19 percent of the energy that was being consumed by the incandescent light fixtures and has reduced its carbon emissions by more than 81 percent at the facility.

Sunovia President Bob Fugerer stated, "The Oaks renovation is a perfect example of the savings and efficiencies that can be achieved when management recognizes the value of innovation. LED lighting is an economically viable and environmentally stable solution to energy-efficient lighting. I am very pleased with the entire Sunovia team that made the Oaks renovation a major success.

Intel's decision to locate a 300mm fab in Dalian, China, has spurred interest in the area for other industries, including LED makers from Taiwan, with Epistar and Everlight Electronics considering building a joint facility there, according to the Taiwan Economic News.If it happens, the combination would form "a relatively dominant conglomerate" with Hon Hai Precision Industry, which already makes LEDs in China, and could "trigger a shakeup in local LED makers' share of China's domestic market" for end applications in autos and streetlights, the publication reports.


Growth of an automotive sector in northeastern China has spurred big demand for LED auto lamps and LED lights here. In concert with national policies to sponsor high-tech industry development, the local Dalian government has approved a 15% income tax rate and 5%-17% tax return rate for companies in the Jinzhou IT Park, about 30 miles from Dalian's economic zone.This energy savings is critical because DRLs built with conventional bulbs consume more power than any other exterior lighting application due to their always-on daylight use, potentially running afoul of today s fuel economy standards.

the GSA can then recommend technologies to its portfolio

This performance improvement is provided by adding a simple TRR reflector with an aperture to standard multi-color LED packages. The diameter of the aperture, which determines the amount of recycling, and the total size of the reflector can be scaled to meet the user's needs. "Clearly, with such improvements in performance with minimum change in configuration will find applications in many areas in the entertainment industry and pico-projectors.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.

Daintree’s ControlScope solution will be used to control existing fluorescent lights in one building and to control Cree’s lights in another building. Powell notes that one of the advantages of LEDs is their inherent controllability, but the agency still doesn’t know if the cost-benefit is right.The point is to see whether or not we can cost-effectively install that at market prices today,” said Powell. But cost isn’t the only factor; occupant satisfaction and maintainability also play a part in evaluating technology.In the case of occupant responsive lighting, the technology saved 27 percent over baseline conditions for spaces illuminated 12 hours a day, five days a week -- and occupants embraced the upgrades. For LEDs, the savings will have to significantly beat what’s achievable with controllable fluorescents to make inroads with GSA.
