In affirming the ITC's interpretation, the Federal Circuit noted that "Epistar does not challenge the infringement determination under the [ITC's] claim construction." Thus, the ITC's ruling that Epistar infringes the ‘718 patent has now been confirmed on appeal. The Federal Circuit also upheld the ITC's decision that "Epistar (as a successor to UEC) may not contest validity of the '718 patent with respect to the UEC products that it inherited in the merger" between Epistar and UEC, but overturned the ITC's ruling that Epistar could not contest validity with respect to other products. Philips Lumileds remains confident that any further invalidity challenges by Epistar to the '718 Patent will be rejected. This confidence is supported by the rulings of U.S. District Court Judge Claudia Wilken of the Northern District of California in an earlier case against UEC granting Philips Lumileds summary judgment on multiple different validity challenges to the '718 patent claims.

A change in the law after the ITC decision in this matter called into question the ITC's long-standing practice of issuing Limited Exclusion Orders that bar importation of downstream products manufactured by third parties not named in the case. The Federal Circuit has vacated the existing Limited Exclusion Order and remanded the case back to the ITC for further proceedings. Philips Lumileds had earlier filed a petition with the ITC requesting that the Limited Exclusion Order be converted into a General Exclusion Order that, even after recent changes in the law, could bar the same non-party downstream products covered by the original Exclusion Order.In addition to the ITC proceeding,YAHAM lighting has a pending patent infringement suit against Epistar in the U.S. District Court before Judge Wilken asserting infringement of not only the '718 patent, but also two other Philips Lumileds patents. The Federal Circuit's decision paves the way for Philips Lumileds' success in that pending dispute.

additional stimulus money through the Department of Energy

LEDs (Light-emitting diodes), which use one-seventh as much energy as conventional lighting and can last much longer, can be used in lamps and fixtures, municipal streetlights and outdoor lighting such as street lamps, traffic signals and auto lights.Micron is seeking to get into the "high brightness" LED market, which an industry expert says did $5 billion in sales in 2008 and is expected to grow to $12.5 billion by 2013. The move could help the shrinking company diversify. Micron is laying off 2,000 people by August as it ends computer-chip manufacturing on its Boise campus.Micron plans to begin work on prototype LED lighting modules in the next three months and produce the prototypes by the first half of 2010. Full production is expected by 2011.

The company's mass-manufacturing experience in semiconductors will allow it to dramatically lower the costs of LEDs by developing the same kind of output efficiencies that have made Micron a leader in its primary field: making dynamic random-access memory, said Mark Durcan, Micron's chief operating officer.Micron already has hired engineers and marketing employees to work on LEDs and said it would leverage $150 million in existing investments in research and development, buildings, equipment, work force and intellectual property.The state proposal is aimed only at Micron's LED business. "It's just that the LED business is ripe and ready," said Kjellander. Micron continues to work on developing a separate solar panel business and is also seeking additional stimulus money through the Department of Energy.

The Micron money would be part of the state's proposal for spending $37 million in energy funds under the American Recovery and Reinvestment Act of 2009. Other money would go to energy-efficiency programs for schools and a pilot plant to install solar panel on five to 10 schools around the state. Energy-efficiency programs for cities and counties and funds to establish renewable-energy enterprise zones also are included.Taiwan Semiconductor Manufacturing Co. (TSMC) recently funded LED lighting maker Liquidleds Lighting Corp. NT$26 million (US$764,700) through its venture capital fund VTFA and has acquired 11% stake in the LED provider. The investment is considered as part of its plan to develop strong presence in green technology field.

The OLED display industry is changing rapidly because OLED displays have very attractive performance: wide viewing angle, wide color gamut at all gray scales, fast response time, low power consumption, thin/light weight and wide operating temperature. Lifetime has improved dramatically in recent years, and red and green lifetimes are long enough for many consumer electronic applications.

All models integrate a charge pump with automatic voltage multiplier switching (x1, x1.5, x2), eliminating the need for an external inductance coil. In addition, UPIC (Uni-Port Interface Control) is utilized to control the 16-stage constant-current driver (0.125mA to 20mA, pseudo-logarithmic curve) with just 1 control line, reducing the number of wires. The ultra-compact package size, coupled with fewer components and wires required, make the ICs suitable for compact, low-profile, applications seeking to minimize size and space, such as mobile phones, solid-state audio players, and Bluetooth headphones.

And more than 40% of the energy consumed by the LCD TVs of the same size will be saved when using the new LED products.

The Z-Power LED products provided by Seoul Semiconductor will emit red and blue lights which can help the growth of plants. As a participant in this project, Seoul Semiconductor had its competitive power proved among its Japanese rivals of advanced technologies. And it has also shown the possibility to expand the LED market into the farming field. With LED supplementary lights as artificial light source in farming, the quality and quantity of plants will be improved and the income of the farmers will also increase.Incandescent lamps, fluorescent lamps and sodium lamps have been generally used in the past. While the new LED lights will offer higher power efficiency and longer lifespan without carbon discharge. According to a report of Rural Development Association of Korea, by replacing the incandescent lamps with LED lights for supplementary lighting in 3,000 hectare of farm, about 70% of the energy will be saved, which amounts to $12M per year.What’s more, with the LED artificial lighting, farming will be possible even in the dessert or the Artic region. Therefore, the application of LED is expected to be a solution of the food problems in many countries.

The new lighting system called "Grace Lumino" has been introduced for applications in convenience stores and hotels with its power monitoring system developed by Daiwa House Industry and color rendering, light distribution as well as the optical design adopted from Nabesho.According to Act on the Rational Use of Energy (Energy Saving Act) in Japan, the power consumption of industrial plants and other places are required to be monitored and reported. And the ECO Monitoring System has been featured in Grace Lumino to meet the demand. This system is especially suitable to be used in the franchise business, for the power consumption of lighting equipments in each chain store can be managed at the headquarters in a centralized manner and the energy consumption can be largely reduced as a result.

Many people already have a strong opinion about it

Dan Francisco, a spokesperson of Micron explained that Micron believes it's uniquely positioned to use its expertise in semiconductor manufacturing industry to help dramatically lower costs for development of these technologies. Plus its research and development team is already familiar with led high bay light this type of technology. Francisco indicated that if granted stimulus funding, Micron could act swiftly on the solar and LED projects with the potential of solar lines being production ready in micron facilities by the end of this calendar year.

The LED lighting would be production ready in 2010. But, with hundreds of other proposals from both public and private interests, Micron has a lot of competition for the cash. The Governor's Executive Stimulus Committee would begin sorting through all the applications. Many people already have a strong opinion about it. They'd like to see Micron given the opportunity to rebound from it's recent slump.Well I think solar energy would be great. We have a lot of that in Idaho, a lot of solar.  We have a lot of wind, so alternative types of energy are always good," said Rep. Jim Patrick.

Once the stimulus committee reaches a decision, Otter will review their findings and present an updated budget to the Joint Finance-Appropriations Committee. Micron says if it is granted a chunk of the money, it could potentially establish Idaho as a hub of manufacturing for green solar and led high bay light.The shipments of notebook PCs with LED backlights reached 3.7 million in the final quarter of 2008 – a 62% rise on the preceding quarter. 13.4% of notebooks shipped in the closing quarter of the year featured LED backlighting technology, compared with a market share of only 6.3% in the third quarter, according to a recent report.

Those solutions for clients such as Dimensional Innovations

Through the process, Dimensional Innovations had not found the combination of quality, performance and price that translated to an encouraging business case. To complicate the challenge, the incumbent fluorescent systems worked adequately, so there was no justification for taking a risk on a customized solution that lacked an equivalent level of performance.Nicolakis concluded that factoring in the reduced maintenance, the ability of led high bay light to run efficiently with a direct 12-volt solar source, the decreased power consumption and the increased quality of the illumination, it's clear that this is yet another case where LED lighting is a superior solution to the incumbent technologies. Greenlight Initiative’s extensive qualification program has allowed them to identify those solutions for clients such as Dimensional Innovations.

Founded in 2006, and with offices in New York, Atlanta, and Quebec, Canada, Greenlight Initiative's mission is to provide clients with LED and other alternative lighting solutions that can replace and outperform incumbent lighting technologies in terms of energy savings, durability, life, and practicality. Through qualitative, real-world testing and laboratory evaluations, Greenlight presents its clients with a broad portfolio of money-saving.The EverGEN 1500 combines the performance of an AC-powered area light with the versatility of an off-grid solar-powered lighting system.

The Austin, TX-based company is venture-backed and led by an experienced team of senior executives with a breadth of experience building and leading thermal and startup companies to success.

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.

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.
