Abstract
A light emitting assembly comprises a plurality of light sources and a solid light emitting panel member having a light input edge and a transition area between the light sources and the light input edge. Light from the light sources enters the transition area and mixes within the transition area prior to entering the panel member. Refractive surfaces on the transition area redirect the light into the panel member. A film is maintained in spaced relation from the panel member by spacers at a perimeter of the film to form a hollow layer between the panel member and the film. Deformities on or in the panel member cause light to be extracted from the panel member and pass through the hollow layer and out through the film.
