Cree is developing to a novel 100 lumens per watt (LPW) solid-state lighting (SSL) component suitable for insertion into SSL luminaires for commercial lighting. To achieve this objective, Cree is building on its high brightness white light emitting diode (LED) platforms to boost the warm white LED efficacy. Improvements to the LED wall plug efficiency, phosphor efficiency, and package system efficiency are being addressed. New phosphor materials are being developed and integrated along with LED chips into a package designed for optimum color mixing and efficacy. Cree will perform the work to deliver 100 LPW lamp modules that emit white light with a color temperature of 3000K by the end of a focused two-year effort. These modules will be integrated into 1250 lumen proof-of-concept luminaires.
