The report notes that the LED lighting business is a market of about $500 million with traditional UV lamp technology. Thanks to its compactness, lower cost of ownership and environmental friendly composition, UV LEDs are expected to replace traditional lamps and also open the door to many new applications, especially portable ones.In 2008, LEDs in the UV A/B spectrum were the dominant device in the sub-400nm applications. More than 90% of the UV LED market (outside of R&D) was covered by UV curing, counterfeit detection, medical and instrumentation applications requiring UV A/B sources. The remaining 10% was allocated to Air & Water purification with again a great portion of led high bay light source for photocatalytic air purification, according to the report. UVA LEDs dominate today but UVC LEDs will lead the market tomorrow, the report notes.

power conversion for hybrid and electric vehicles
When compared to a silicon IGBT module of equal rating, and operating at a junction temperature of 150 degrees C, the SiC MOSFET-based module has 38% lower conduction losses and 60% lower switching losses for a total power-loss reduction of 54% when operated at 20 kHz. The combination of both low conduction and switching losses make this module ideal for any application where high efficiency is critical—such as solar energy power inverters and electric drives, and power conversion for hybrid and electric vehicles.
The all-SiC module has been jointly developed using materials and assembly processes common in the industry, offering a clear path to volume production. The module can also be easily scaled for higher currents and the layout can be modified for other switch configurations.YAHAM chief technology officer, power components and RF devices, indicates that these 1200-Volt, 100-amp SiC MOSFET modules represent the next level of integration for SiC power devices. They represent a critical milestone in the technology progression toward high-reliability, energy-efficient power conditioning and control. Further, the component-efficiency advantage of this technology is highly relevant in the current energy-conscious environment and could translate to significant energy savings for hybrid and electric vehicles, solar power inverters, and industrial motor drive systems.
The power electronics section lead for AFRL’s Propulsion Directorate, notes that the practical realization of the SiC high-temperature, power, and frequency performance entitlement, on a pervasive scale, is coming to fruition. With its inherent high-temperature operational capability, this technology will be widely applicable to high-reliability military and commercial-system power conversion applications.Powerex is a leading supplier of discrete, modular and integrated high-power semiconductor solutions. Powerex’s broad product line—including IGBTs;Discrete Rectifiers and Thyristors; and Thyristor and Diode Modules—is enhanced by its divisions devoted to the development of custom modules and customer-specific assemblies.

its constant current output can last LED lifetime over the long-term
The output current for each LED is enabled, disabled and controlled by AnalogicTech's Simple Serial Control interface. By replacing PWM control circuitry, this 32-step single-wire bus reduces the overhead on the system microcontroller, minimizes LED flicker through constant-current digital control, and reduces noise.The company focuses its design and marketing efforts on the application-specific power management needs of consumer, communications, and computing applications in these rapidly evolving devices. AnalogicTech also develops and licenses device, process, package, and application-related technology.The company says the new led high bay light have four main functions which include a modulized design, a unique cooling technology, a new optical design, and an excellent power module. The fixture is streamlined and ultra-thin, with a depth of only 80mm and will be expected to meet the global market demand. The company currently plans to mass-produce 55W and 105W street lights that can be used with either solar or AC power.
Opto Tech says that it considers practicability as the highest priority. Therefore, the internal structure is designed with a patented module with a hinge and E-type ring buckle, which means its maintenance or replacement can be performed by one person. The company describes its product as a “breathing street light” due to its “unique” cooling technology. The heat generated by the optical module is quickly and effectively removed via a copper heat pipe connected to an aluminum heat sink positioned below ventilation holes in the bottom cover.The optical design meets international standards after going through precise optical testing, with a perfect butterfly-shaped photometric curve that was designed with driving safety in mind. The product’s photometric curve produces better illumination and achieves a more comfortable lighting effect than other competitors, claims the company. Meanwhile, the power module has 90% and above conversion efficiency and its constant current output can last LED lifetime over the long-term.
The 105 W street light has a color temperature of 5200 K and a color rendering index (Ra) of 70. The power factor is given as 0.912-0.989, and the efficiency of the power supply is 95%. The total lumen output with a clear cover is given as 8640 lm.Currently, the products have passed the testing and verification standards and new patents have been applied for in the USA, China, and Taiwan. Those that have already inquired about and ordered this product include government agencies and businesses from various countries, says Opto Tech.The company says its LED assemblies and arrays can be customized to include different levels of indicating brightness for each LED within the same unit to meet a specific indicating goal. For example, a dual led high bay light assembly may have one continuously lit dimly to indicate normal conditions. When triggered, the second LED within that assembly would not only illuminate a different color, but also a different brightness to indicate the severity and urgency of this problem.

the portfolio of LED subsystem capabilities
The LED lights themselves are now at a performance that make them viable, even attractive, alternatives today. I couldn't say that five years ago," Meirav said. What's holding back the rate of adoption has less to do with the technology and more to do with an industry supply chain still focused on incumbent lighting technologies. "That's the rate-limiting step in replacement process. It's beginning to happen now, but lighting is not a fast-moving industry--not like computers or telecom," he said.Meirav expects led high bay light companies to benefit from a federal stimulus package now making its way through Congress. The package includes incentives for municipal buildings to invest in energy efficiency.
The acquisition of Opto Technology adds optical subsystems to PerkinElmer's portfolio of high-brightness LED components, and will help PerkinElmer provide solid-state lighting products to original equipment manufacturers (OEMs) serving the health, safety and security markets.Opto Technology's annual revenues are under $15 million, David Nislick, president of PerkinElmer's Illumination and Detection Solutions business, said. "The addition of Opto Technology expands PerkinElmer's presence in the solid state specialty lighting marketplace and broadens the portfolio of LED subsystem capabilities that we can provide to our customers."
"We are excited by the opportunity to become part of PerkinElmer, combining PerkinElmer's strength in providing lighting solutions to health and environmental OEMs around the globe with Opto Technology's innovative solid-state technology capabilities," said Thomas Hegberg, president and CEO of Opto Technology, Inc. “A core part of our mission has been designing energy-efficient lighting systems that make the world a brighter, healthier, safer and greener place to live,” added Hegberg. “We are delighted that there is such clear synergy with PerkinElmer's strategic focus.Virtually maintenance-free, the Halo LED fixture could deliver over 70% of the led high bay light over 20 years when used six hours per day. Plus, for additional energy savings, the LED module is dimmable to approximately 15% using standard AC incandescent analog dimmers and approximately 5% with dimmers that have a low-end minimum brightness adjustment.

LED lamps have been performing poorly
Although Nichia has been known for its globally brightest white LED emitters, the company has made the chips for its own packaging lines. Taiwan industry watchers pointed out Nichia now wants to boost the sales of led high bay light its chips worldwide in light of growing LED market.During the company’s investor and analyst day, this move was initially indicated. Philips said the value adjustment was a consequence of reduced short-term market demand and uncertain outlook caused by the current macro economic downturn.
Department of Energy (DOE) has released the first draft of Energy Star criteria for integral LED lamps and has posted these potential criteria on its web site. DOE has also explained why integral LED lamps are being included in the Energy Star program at this point and given an overview of the approach the agency took to decide on certain criteria. Also listed are several key issues that are up for debate and the expected timeline for revising and finalizing these criteria.The DOE believes that integral lamps are now emerging as technically and commercially viable products. However, since many LED lamps have been performing poorly, some energy efficiency program sponsors have repeatedly been asking for minimum performance guidelines. Thus, setting requirements now, at the early stages of the lamps’ market viability, provides targets that manufacturers can meet to please program sponsors and eventually the public.
LED is energy-saving, vibration resistant, compact, and low in power consumption and attenuation; it also has other numerous advantages such as long service life, suitable for low-temperature environments, and high luminous efficiency. LEDs have much potential in indoor lighting development, yet their cooling problem is the bottleneck that affects high-power led high bay light to be popularized.To solve this problem, Sunon, the leading company in global cooling solutions, devised an LED indoor lighting cooling module solution in combination of elastic designs of fans and cooling modules. Sunon, at this very moment, announced that the firm have made a significant step in developing solutions for LED indoor lighting cooling modules!

consist of products for households
Brilliance Technologies runs a 2,500-square-meter factory staffed by 90 workers, who turn out mostly LED projector lamps, led high bay light bulbs, and LED wall-wash lamps. It now exports 50,000 lamps monthly mainly to the European Union, Northern Europe, the U.S., Korea, Japan, Southeast Asia, and the Middle East; but the supplier is currently only filling orders received amid the global economic slowdown. Considering the strong demand for LED lighting, Cai Minhan, company manager, is upbeat about corporate development as long as it continues to build quality products that meet market needs.
A joint venture between Chinese and foreign businesses, Shunde Corso operates a 10,000-square-meter plant that turns out home-appliances and lighting. The lighting factory produces high-performance energy-saving lamps and ballasts, with the energy-saving lamps available in 2U, 3U, spiral, and shaded models, which are 80% more energy-efficient than incandescent counterparts. Its current monthly output of 600,000 lamps, sold domestically and overseas, consist of products for households, restaurants, commercial premises, roadways, and gardens. Besides being ISO9001-approved, the company builds client loyalty by offering top quality, which is achieved by sizable investments in R&D.
LED lighting has long held the promise of replacing energy-thieving incandescent bulbs without the drawbacks of fluorescent lighting and is finally taking hold in some sectors of the marketplace, says Chuck Swoboda, CEO of yaham Inc.YAHAM is leading the LED lighting revolution and setting the stage to obsolete the incandescent light bulb through the use of energy-efficient, environmentally friendly led high bay light. Chuck Swoboda, as the CEO of Cree Inc. has served since June 2001. He noted Cree has known for the last four or five years it could do solid state LED lighting. Meanwhile, commercialization took a while because the company first had to develop the LED chip technology and incorporate it in LED components.

The developed lighting solutions incorporate solid state lighting technology
Since January 2003, Ingram has served as vice chairman Pharmaceuticals of GlaxoSmithKline, a pharmaceutical research and development company in Research Triangle Park, North Carolina. He previously served as chief operating officer and president of Pharmaceutical Operations of GlaxoSmithKline following the December 2000 merger of Glaxo Wellcome plc and SmithKline Beecham plc. Prior to the merger, he served as chief executive officer of Glaxo Wellcome plc and as chairman, president and chief executive officer of Glaxo Wellcome Inc. He also serves on the boards of directors of led high bay light, Allergan, Inc., and Edwards Lifesciences Corporation, and also as chairman of the board of directors of OSI Pharmaceuticals, Inc. and as lead director of Valeant Pharmaceuticals International.
The company said that plans for the plant were to deliver a monthly production capacity of three billion LED chips. Despite the economic slowdown, Opto Tech is planning to increase its capacity at its facility in Taiwan. The company has reportedly ordered four sets of MOCVD (metal oxide chemical vapor deposition) systems. Two of the sets are currently being installed in its Taiwan plant and they are set go begin production in March 2009; the other two systems will not be put off until some time in 2009. The company hopes to capitalize in the increasing demand for LED backlit displays.The company’s LED lights are part of a continuing effort to reduce energy and maintenance costs. The fixtures and underlying technology were developed under the Defense Advanced Research Projects Agency (DARPA) High Efficiency Distributed Lighting (HEDLight) program. The installation comes after a year-long demonstration on board naval vessels that replaced existing fluorescent, incandescent, and halogen lighting with various HEDLight lighting solutions.
The developed lighting solutions incorporate solid state lighting technology. The fixtures include highly efficient and long lasting (LED) globe fixtures with a power savings of up to 87%, and led high bay light berth lights for general berthing compartments, which provide a 14% power savings. All fixtures were designed to be direct replacements to eliminate retrofit concerns and reduce installation costs.Roger Buelow, CTO of Energy Focus, noted that the improvement in visibility and amount of light in the work area is as impressive as the energy and maintenance savings, these 60 lumen per watt fixtures, operating at more than four times the efficiency of the ones they replaced, give the sailors more and better light to work under.
