At least one light emitting diode produces light which is subsequently diffused to broaden an angle of projection for use in collimating reflector type flashlights. A light dispersion location is formed by the light produced following the diffusion of the produced light. This light dispersion location,...http://www.google.ca/patents/US6502952?utm_source=gb-gplus-sharePatent US6502952 - Light emitting diode assembly for flashlights
