| 20090257244 | LIGHT EMITTING PANEL ASSEMBLIES - Light emitting panel assembly includes a panel member, at least one light source and a light transition member located between the light source and the light input surface of the panel member. On or in the light transition member are elements that effect a desired colored or white light output distribution from a light output area of the panel member. The light transition member may comprise a coating or surface treatment on the light input surface that effects the color of light emitted by the light output area. Alternatively a transparent sheet, plate or film attached to or positioned against the light input surface may have a coating, surface treatment or deformities that effect the color of light passing through the sheet, plate or film to obtain a desired colored or white light output distribution from the light output area. | 10-15-2009 |
