Patent ID: 7980728

Claim:
A lighting apparatus for providing general lighting in a region or area intended to be occupied by a person, the apparatus comprising: one or more solid state light emitters, the one or more solid state light emitters producing light intensity sufficient for a general lighting application; an assembly outside an enclosure of the one or more solid state light emitters, the assembly forming an optical integrating volume for receiving and optically integrating light from the one or more solid state light emitters and for emission of integrated light in a direction to facilitate said general lighting application, the assembly comprising: a reflector having a diffusely reflective interior surface defining a substantial portion of a perimeter of the optical integrating volume; and a light transmissive solid, having: a) a light emitter interface region for each solid state light emitter closely conforming to the light emitting region of each solid state light emitter, b) a surface conforming closely to and in proximity with the diffusely reflective interior surface of the reflector, and c) a light emission surface at least a portion of which forms a transmissive optical passage for emission of integrated light from the optical integrating volume in a direction to facilitate said general lighting application in the region or area, wherein the light transmissive solid fills at least a substantial portion of the optical integrating volume.
