Abstract
The first panel illumination system includes a high intensity light source with a contoured reflector assembly for providing light to the input of an optical mixer and heat removal device. The optical mixer and heat removal device removes infrared radiation and transmits de-focused light to the input ends of a plurality of rectangular couplers connected to light conducting cables which are in turn connected to the light emitting optical fibers for a light emitting panel. These fibers are woven in accordance with specific weave ratio ranges and weave configurations to emit light uniformly across the extent of a light emitting fabric surface.
