Abstract
Low profile, thin panels using a layer of clear cast polymer with a reflective, mirrored backing and edges and a light diffusing face sheet, carrying light sources using fiber optic lenses or diodes on all or any sides thereof. The reflective sides direct the light beams generated at the edges toward the center and opposing sides, reflecting light beams within the cast plate, diffusing the light towards the open surface. Overall thickness of the panels is not more than 1/2'' and light sources are inserted into the edging before a liquid polymer mix is cast over them, to create an integral element upon curing. The liquid polymer mix, with any additives to deliver different colors, is poured into a tray with reflective inner surface and side edges, which houses the light sources. The finished panels may have framing to cover any wiring or exposed edges.
