ABSTRACT:
An illumination system includes a light guide for distributing light. Extraction structures are provided to uniformly extract light from the light guide. The structures extract more light out of the light guide when light is propagating in the light guide in a direction toward the light input area than when light is propagating in the light guide in a direction away from the light input area.
