SiC makes LED performance better and pricing easier
CREE says it has made a breakthrough in LED technology that completely redefines the lighting industry and erases old assumptions about up-front LED cost and performance. Based on the new SiC technology platform, the XT-E LED and the recently released XB-D LED represent a change in LED price and performance. Cree’s platform addresses the largest obstacle to mass LED lighting adoption, initial cost, and enables LED lighting systems to replace their ancestors.
“Cree has a history of delivering LED solutions,” said Fritz Morgan, chief product officer, Digital Lumens. “We are committed to building the most energy-efficient industrial lighting systems and the XT-E LED enables us to do just that with high lumens per watt. The result is an intelligent LED-based lighting system that is driving widespread adoption of LEDs in industrial facilities, with compelling performance and end-user payback.”
The XT-E LED more than doubles the lumens per watt of the XLamp XP-E LED family – providing up to 148 LPW at 85°C (or up to 162 LPW at 25°C) at 350mA. The XT-E LED delivers exceptional performance in the popular 3.45mm x 3.45mm XP footprint and can be used for almost all lighting applications.
By leveraging the XP footprint, customers can easily incorporate the XT-E LED in existing XP LED designs to shorten the LED fixture design cycle and improve customer time-to-market.
Additionally, since the XT-E White LED is a successor product to XP-E High Efficiency LED, the application for ENERGY STAR qualification requires only 3000 hours of XT–E LED LM-80 data .
“Our mission is to drive the LED lighting revolution through our relentless pursuit of innovation and by helping manufacturers
XLamp XT-E White designed to
accelerate LED adoption and
lower system cost
bring high-quality, affordable LED lighting to market,” said Mike Watson, Cree senior director marketing, LED components. “With the XB-D LED, Cree changed the game and introduced a better price- performance curve. Now, with the XT-E LED, Cree continues to break barriers and extend its leadership on this new trajectory, delivering products that accelerate LED adoption.”
Cree says the XT-E White LED delivers up to 148 lumens and 148 lumens per watt in cool white (6000 K) or up to 114 lumens and 114 lumens per watt in warm white (3000 K), both at 350 mA, 85°C.
GaAs device revenue grows a mere six percent in 2011
THE STRATEGY ANALYTICS report, “2011 GaAs Device Revenue Falters after Strong Start,” explores GaAs device revenue growth trends in handsets and smartphones. It also explores revenue performance of leading substrate and device manufacturers, like IQE, VPEC, Kopin, RFMD, Skyworks, TriQuint Semiconductor, Avago Technologies and WIN Semiconductor. While growth drivers are still present, the rates are likely to flatten in 2012.
“Tremendous growth in the smartphone segment of the handset market in 2010, and the early part of 2011, had propelled the overall GaAs market to record levels of revenue which are now
slowing,” commented Eric Higham, Director of the Strategy Analytics GaAs and Compound Semiconductor Technologies Service. “However, increasing GaAs content in handsets and the sheer volume of the handset market should still power GaAs growth.”
Asif Anwar, Director, Strategy Analytics Strategic Technologies Practice, added, “There were revenue declines in the second half of 2011 at GaAs substrate manufacturers. Strategy Analytics will continue to monitor these trends throughout 2012, in order to see their effect on the GaAs supply chain.”
Veeco K465i is the logical choice according to SemiLEDs
SEMILEDS has recently qualified the TurboDisc K465i GaN MOCVD System for high-volume production of high brightness LEDs at its state-of-the-art manufacturing facility in Taiwan.
“We have placed Veeco’s K465i system into our production facility in Taiwan. In addition to their proven MOCVD technology, Veeco’s commitment to providing best-in-class LED manufacturing equipment, as well as enhanced local support with their technology centre in
Hsinchu, makes the selection of Veeco as our vendor a logical choice,” said Chuong A. Tran, President and Chief Operating Officer, of SemiLEDs.
William J. Miller, Veeco’s Executive Vice President, Process Equipment, added, “We are very pleased SemiLEDs chose Veeco to be a new supplier of MOCVD equipment. Our TurboDisc K465i platform consistently offers excellent productivity while keeping production costs low. Our Taiwan Technology Centre will help the
