ABSTRACT:
The light output of a back-coupled illumination system is improved by recycling reflected and misdirected light rays. A reflector at the light source and an array of microprisms having reflective elements therebetween efficiently redirect errant light rays to increase the total available light output and improve efficiency. Both specular and diffuse reflective materials may be used in combination to enhance light output.
