Patent ID: 7635874

Claim:
A light emitting diode (LED) assembly comprising: an edge-emitting LED stack comprising: a first external emitting surface, the first external emitting surface configured to be non-reflective, thereby accommodating transmission of incoherent light out of the edge-emitting LED stack without reflecting light back into the edge-emitting LED stack; a second external surface comprising a p-type contact; a third external surface comprising an n-type contact; a fourth external surface opposing the first external emitting surface; and a reflective element located adjacent to at least one external surface of the LED stack, the at least one external surface excluding the first external emitting surface and the fourth external surface, the reflective element configured to reflect incoherent light that is generated in an active region of the LED stack back into the LED stack, wherefrom at least a portion of the reflected light is emitted out of the first external emitting surface along with incoherent light emitted directly from the active region of the edge-emitting LED stack.
