Light emitting panel assemblies
First Claim
1. A light emitting assembly comprising a multilayer light emitting panel member having at least one solid light conducting or transmitting layer and at least one hollow light conducting or transmitting layer, two or more light sources positioned in at least one slot, cavity, recess or opening in the solid light conducting or transmitting layer, the solid light conducting or transmitting layer having deformities on or in at least one surface of the solid light conducting or transmitting layer to cause light from the light sources that mixes in the solid light conducting or transmitting layer to be emitted into the hollow light conducting or transmitting layer for further mixing of the light in the hollow light conducting or transmitting layer, and at least one film, sheet, plate or substrate positioned in close proximity to the panel member to direct the light emitted from the hollow light conducting or transmitting layer in different directions to produce a desired output distribution or effect.

Abstract
Light emitting assemblies include a panel member having two or more light sources, and at least one film, sheet, plate or substrate positioned in close proximity to the panel member with an air gap or cavity therebetween. Deformities on at least one surface of the panel member cause light from the light sources that mixes in the panel member to emit from the panel member. The air gap or cavity and the film, sheet, plate or substrate improve the uniformity of the light output distribution from the assembly.
