ABSTRACT:
A transparent edge-lit window pane for lighting displays and the like through which maps, pictures and photographs which are illuminated thereby can be viewed by an observer includes a generally rectangular panel of transparent material tapering from one edge to the opposite edge to form a wedge shape, a linear light source imbedded in and sealed thereto along the one edge with a sealant having an index of refraction close to that of the panel and etching on one planar surface of the panel whereby it greatly increase the amount of light egressing from the pane toward the display without clouding the chart from the observer. The linear light source may include a semi-circular length-wise reflector to increase the amount of light entering the edge of the pane from the light source.
