Abstract:
1. An illumination assembly, comprising: an asymmetric diverging wedge defined by a narrow end surface and a wide end, and opposing side surfaces that are not parallel and extend between the narrow end and the wide end; a solid state light source disposed adjacent to the narrow end surface, the solid state light source emitting light into the diverging wedge through the narrow end surface; a light guide optically coupled to the wide end, the light guide having a light reflection surface as a first major surface and a light emission surface as a second major surface opposite the first major surface with an edge surface between the first and second major surfaces, and one of the opposing side surfaces being co-planar from the narrow end surface to the wide end with either the light emission surface or the light reflection surface; a reflective layer disposed parallel with and adjacent to or on each of the opposing side surfaces; and an air gap disposed between the reflective layer and each of the opposing side surfaces, wherein the diverging wedge and the light guide form a unitary body, wherein the light emission surface functions as a luminaire, and wherein the wedge primarily propagates light by total internal reflection.
