Illuminating devices including uniform light distribution, multiple light sources, and multiple types of light sources

Abstract

A lumenaire for mixing and emitting light from multiple light sources which has at least one first light source of a particular type and at least one second light source of a differing type. There is an optical system which includes at least one individual light collecting optical element at least partially surrounding each light source. There is a substantially planar light guide that receives and transports the light from each of the individual optical elements and optically mixes and emanates the light from both types of light sources simultaneously, through a common surface of the planar light guide. The planar light guide is segmented and the segmented sections are angularly disposed, in section in relationship to each other and the individual optical elements project light into at least one of the segments.
