Cree doubles brightness of EZBright LED power chip for lighting applications

Cree Inc has released a new version of its InGaN-based EZBright LED power chip. EZBright1000 LEDs are twice as bright as Cree's current power chips, and are designed for general lighting applications, such as home and office
lighting, auto headlamps, streetlights, and garage and warehouse low-bay lighting, as well as consumer applications including flashlights, camera flash and projection displays.

"For the first time, these chips should enable solid-state lamp makers to challenge the efficacy of not only incandescent, but also fluorescent lamps," said chairman and CEO Chuck Swoboda. "The EZBright1000 LED power
chip is one of several advancements we are working on to help drive LEDs into more mainstream lighting applications."

Measured as a bare die, ethe blue LED exhibits power output up to 370mW at 350mA drive current and 800mW at 1A drive current. "This product should enable our customers to reach new levels of power output and efficiency from a single chip and redefine what is possible with power LEDs," claims Scott Schwab, vice president and general manager of optoelectronics.

The EZBright1000 power chip is the third product based on the EZBright platform, which features a proprietary optical design that delivers an optimal Lambertian radiation pattern, with low emission losses and high efficiency. It incorporates technology that was developed in part with
support from the US Department of Energy's National Energy Technology Laboratory and the US Department of Commerce's National Institute of Standards and Technology, Advanced Technology Program.

Additional EZBright products will be released over the next several months, says Cree.
