1. A light emitting assembly comprising:

  • a plurality of light sources,a solid light emitting panel member having a light input edge and a transition area between the light sources and the light input edge, whereby light from the light sources enters the transition area and mixes within the transition area prior to entering the panel member through the light input edge and propagating within the panel member by total internal reflection, the transition area having refractive surfaces for redirecting the light into the panel member,a film maintained in spaced relation from the panel member by spacers at least at a perimeter of the film to form a hollow layer between the panel member and the film, anddeformities on or in the panel member that cause light to be extracted from the panel member and pass through the hollow layer and out through the film which redirects the extracted light in desired directions to produce a desired output distribution or effect.
