Cree First to Break 300 Lumens-Per-Watt Barrier
DURHAM, NC -- Cree, Inc. (Nasdaq: CREE) records another significant LED milestone with the demonstration of 303 lumens per watt from a white, high-power LED. Reaching the landmark achievement much faster than previously believed possible, this result surpasses Cree’s previous R&D industry-best of 276 lumens per watt announced just over a year ago.“This is truly an impressive accomplishment. Achieving this level of LED efficacy amplifies the potential for the solid-state-lighting industry to deliver smaller, lower-cost lighting solutions, and even larger-than-expected energy savings,” said Steven DenBaars, professor and co-director, Solid State Lighting and Energy Center, University of California, Santa Barbara.
Cree reports that the LED efficacy was measured at 303 lumens per watt, at a correlated color temperature of 5150 K and 350 mA. Standard room temperature was used to achieve the results.
The development of LEDs currently focuses on more compact shapes, a higher luminous flux, and better luminous efficacy as well as a more economical production process. A further goal is the reduction of production-related color deviations. Manufacturers sort LEDs by luminous flux and dominant wavelength and give them a bin code and a rating. This sorting of LEDs is called binning.
