ABSTRACT:
A light-condensing reflector positioned at the opposite side or end of a light source from a primary paraboloidal reflector in opposed reflector-to-reflector relationship to amplify light. The light-condensing reflector is selectively smaller in diameter than the primary reflector such that an annular or ring-like light orifice is formed between the outside periphery of a base of the light-condensing reflector and the inside periphery of a base of the primary reflector. Light amplified and condensed by the two opposed reflectors is collimated in an annular light beam through the annular light orifice. When applied to flashlights, spotlights and vehicle headlights, this invention increases the light intensity substantially.
