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.
