摘要

An apparatus and method for extraction of light from a light conducting medium in a preferred emanation pattern are described. In one embodiment, the apparatus comprises a first light conducting sheet including aspherical particles, and a light source placed along the edge of the first sheet. The first sheet diffuses light generated by the light source such that light emanates in a predetermined light emanation pattern.
