Patent ID: 7434973

Claim:
A light emitting panel assembly comprising a light emitting panel member having at least one input edge, a plurality of light sources optically coupled to different portions of the width of the input edge, and a pattern of individual light extracting deformities associated with respective light sources, wherein the deformities are projections or depressions on or in at least one surface of the panel member for producing a desired light output from the panel member, wherein each of the deformities has a length and width substantially smaller than the length and width of the panel surface, wherein the deformities that are in close proximity to the input edge increase in density, size, depth and/or height as the distance of the deformities from the respective light sources increases across the width of the panel member, and wherein the density, size, depth and/or height of the deformities in close proximity to the input edge is greatest at approximate midpoints between adjacent pairs of the light sources.
