February 20, 2006—Cree, Inc., a leader in LED solid-state lighting components, has announced the general availability of the industry’s highest efficacy white power LEDs at 350 mA. Cree’s white XLamp 7090 power LED package achieves a typical efficacy of 47 lumens per watt at a drive current of 350 mA, and 57 lumens of typical light output.
Cree also announced the availability of XLamp 7090 in warm white (2700-4500 degrees K) to address the emerging market for residential lighting applications.
“To replace the light bulb cost effectively with solid state technology, LED manufacturers have to maximize the efficacy (lumens/watt) of their high- power LEDs. Energy savings is the most important metric as we build the business case for the residential lighting fixtures of today,” notes Manuel Lynch, Permlight Products president and CEO. “Cree has done a terrific job of providing us with highly efficient power LEDs allowing us to replace incandescent and compact fluorescent technologies in new homes throughout California. We are currently selling under counter, step and pathway light fixtures based on the white XLamp 7090 power LED.”
The XLamp 7090 power LED also features reduced thermal resistance to 8 degrees C/watt, electrically neutral thermal paths, allowing use of economical printed ircuit boards, and reflow solderability.
Cree, Inc. is a market-leading innovator and manufacturer of semiconductors that enhance the value of LED solid-state lighting, power and communications products by significantly increasing their energy performance. For more on the company, see its Web site.
