ABSTRACT:
The present invention describes a light mixing waveguide including a transparent slab waveguide having a reflectorized edge, a pair of opposing side edges adjacent to the reflectorized edge, a light transfer edge opposite the reflectorized edge, and a plurality of cavities formed inside the slab waveguide, wherein at least one of the side edges is configured to receive light from one or more light sources so that the received light is totally-internally reflected from top and bottom surfaces of the transparent slab waveguide. Interaction of the received light, the cavities, and the reflectorized edge mixes the received light prior to the light passing through the light transfer edge and into a target optical system.
