ABSTRACT:
A reflector system for a flashlight or the like includes a rear reflector of at least partially parabolic shape and a light source mounted at the focus of the parabolic reflector surface. A lens is mounted between the light source and the open forward end of the reflector to occlude any light beams which would otherwise travel uninterrupted from the light source out of the open forward end of the reflector. The rear reflector may include a spherical surface portion at its center for intensifying the light source, and a collimating pillar of transparent material extends inwardly from the center of the forward end of the reflector towards the lens for collecting light re-directed by the lens, and mixing and breaking up any image forming rays.
