light output requirement for LED lighting fixtures

LEDs are inherently durable and long-lasting components. However, achieving the LED's long lifetime performance requires careful design and testing of the electronic power and control systems and the thermal network. The extensive characterization and reliability testing that OptoElectronix incorporates into every product is the result of its extensive experience in LED and semiconductor technology product development and manufacturing.OptoElectronix estimates that the solid-state lighting (SSL) light engine market, which includes the LEDs, thermal network, power driver circuitry, and optics -- all incorporated into one module -- will be approximately $5.516 billion in 2012.

 The application circuit with BCR 450 has low component count and is free of inductors, capacitors and free-wheeling diode resulting in a very small PCB space requirement. This includes the elimination of electrolytic capacitors which limit the lifetime of switch-mode driver solutions. Infineon also implemented an effective thermal shut down feature and over-voltage as well as over-current protection into the device.

Additionally, the BCR 450 with its output current precision varying only +/-10 percent over the entire operating temperature range strongly supports the homogenous light output requirement for LED lighting fixtures.The world’s largest semiconductor maker has undergone a worst profit drop in seven years in the global recession. Chang said that the company could start out first purchasing a small company, and use that as a nucleus for growth. The company is considering buying companies in solar and LED sections. Chang didn’t identify any acquisition targets or specify investment amounts.

while all of hit new record quarterly highs

As a result, to increase greenhouse yields and decrease producers' energy costs, they will team up with Rutgers University, the University of Arizona, Michigan State University, and Orbital Technologies Corp. on the four-year project to improve and evaluate LED lighting for greenhouse use, according to Cary Mitchell, a professor of horticulture and project director for the grant. Total sales from January through September of 2010 hit NT$92.88 billion, up 35% YoY. Meanwhile, operating profit and net profit reached NT$5.67 billion and NT$6.8 billion respectively, with accumulated EPS of NT$3.05 increasing a remarkable 50% YoY. In 3Q10, The Company’s gross margin and operating margin reached 13.9% and 6.7%, up 0.9% and 0.4% QoQ, respectively. Lite-On’s net cash position held steady at NT$11.9 billion, after its recent cash dividend distribution of NT$5 billion. Non-operating items posted a net income of NT$508 million in3Q, with Perlos’ Q3 sales reaching €138 million, up 12% YoY. Perl...

Universal Display will develop new technologies and processes for OLED manufacturing

In addition to the patent sale, the 2 companies are engaged in “a strategic relationship,” with strengthened and enhanced alliances between the companies. Fujifilm will expand its business for the supply of Fujifilm's highly functional materials, such as barrier films, conductive films and flexible substrates, to OLED manufacturers globally, including Universal Display's worldwide customer base. Universal Display will develop new technologies and processes for OLED manufacturing. John R. Peeler, Veeco’s Chairman and Chief Executive Officer, commented, “Veeco continues to deliver solid results in a soft market. Second quarter revenue was $137 million, and adjusted EBITA and non-GAAP earnings per share were $20 million and $0.37, respectively, with gross margins of 45%. Veeco generated about $19 million in cash flow from operations, ending the quarter with $540 million in cash and short term investments.” Second quarter LED & Solar revenues were $87 million, including $75 mil...

the adoption of energy-efficient LED lighting across their campuses

Nuventix SynJet coolers are available now and already providing silent operation, long life, and optimal cooling to allow designs to incorporate the increased brightness necessary for large-scale commercial and consumer product acceptance. Bias SynPower modules are available in sample quantities. The workshops were key first steps in the launch of a new DOE SSL research and development (R&D) manufacturing initiative to enhance product consistency and quality and to accelerate cost reductions through manufacturing improvements. More than 350 total participants—chip makers, fixture and component manufacturers, and others—joined DOE at the workshops to examine underlying issues related to materials, equipment, and other factors that influence SSL product quality and cost. The Fairfax workshop attendees identified key barriers and recommendations toward lower-cost, higher-quality SSL products, and this input was used to develop a “strawman” roadmap for review at the Vancouver worksho...
