Abstract:
A light emitting panel assembly comprising a light emitting panel member having a greater width than thickness and opposite ends and sides and top and bottom surfaces, a light transition area located at one of said ends, and at least one light source mounted to said light transition area, said panel member having a light input surface at said one end for receiving light from said light transition area, said light input surface having a cross sectional area extending the entire width and thickness of said panel member at said one end, and said light transition area having a light output surface of the same width and thickness as said light input surface at said one end and a reflective surface in close proximity to said light source shaped to cause internal reflection of a portion of the light emitted from said light source and redirect the internally reflected light into said light input surface at said one end to produce a uniform density of light across substantially the entire cross sectional area of said light input surface at said one end, said reflective surface extending around and behind said light source.
