the greenest light source for the applications discussed in this paper


An applications-based analysis of life-cycle energy use is more reflective of what users will experience," said Steven DenBaars, professor and co-director of the Solid State Lighting & Energy Center, University of California Santa Barbara and Cree technical advisor. "LED lighting is clearly the most efficient and the greenest light source for the applications discussed in this paper."

The usage phase of energy-efficient lighting dominates the lifetime energy consumption – with 96 to 98 percent of energy used to generate light and less than four percent due to the manufacturing process.

To meaningfully compare lighting efficiencies, lighting applications must be included, not just light sources.

Today LEDs are the most efficient choice for the high-volume lighting applications of residential and commercial recessed downlights and narrow-beam spotlights.

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...
