Patent 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.
