Light emitting panel assemblies
DC
First Claim
1. A light emitting assembly comprising at least one light source and a light emitting panel member having at least one light emitting surface, and at least one light input surface for receiving light from the light source, the panel member having a pattern of deformities on or in at least one surface to cause light to be emitted from the panel member, and a transition area between the input surface and the at least one light source, the transition area having multi-faceted, refractive surface means in close proximity to the light source for changing the light output ray angle distribution of the light source to a greater extent in a plane substantially parallel to the light emitting surface.

Abstract
Light emitting assemblies include a light emitting panel member having at least one light input surface for receiving light from at least one light source and a pattern of deformities that vary on or in at least one surface to cause light to be emitted from the panel member. At least a portion of the light input surface may have faceted reflective or refractive surfaces or a lens array in close proximity to each light source for maximizing or otherwise changing the light emitted from each light source.
