ABSTRACT:
A light emitting device containing an array of directional emission LEDs is provided. The directional emission LEDs of the array may be substrate emitting, lateral current injection, resonant cavity LEDs mounted in a flip-chip configuration. Each LED may emit a different color of light, such that the output of the array appears white to an observer. The LED array package may contain microoptical elements, such as a diffraction grating or microprisms, integrated into the light emitting surface of the package. The microoptical elements are used to mix the light beams emitted by individual LEDs in the array.
