Light emitting panel assemblies
First Claim
1. An optical assembly comprising a light emitting panel member having a top surface and a bottom surface and at least one light input edge for receiving light from at least two different colored light sources, and a pattern of a plurality of individual optical deformities of well defined shape that are projections or depressions on or in one of the top surface and the bottom surface, wherein the optical deformities on or in the one surface are quite small in relation to a width of the one surface, and wherein the pattern of optical deformities on or in the one surface contains at least two different configurations of optical deformities to promote the mixing of color from the different colored light sources within the panel member and to cause light of a preferred color to be emitted from at least one of the top surface and the bottom surface of the panel member and wherein the different configurations of optical deformities differ in at least one of the following characteristics:
- shape, angle or index of refraction.

Abstract
Optical assembly includes a light emitting panel member having at least one light input area for receiving light from two or more different colored light sources. A pattern of individual optical deformities on or in at least one surface area of the panel member contains at least two different configurations of optical deformities to promote color mixing within the panel member and cause light of a preferred color to be emitted therefrom.
