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.
A light beam amplifier comprising: a light source; a generally conical primary reflector having a vertex at the light source and an opening at a base at the opposite side of the light source; a light-concentration reflector having a diameter selectively smaller than the primary reflector at the opposite side of the base from the light source and positioned to reflect light and heat back toward the primary reflector and the light source; an annular light emission orifice adjacent to and extending between the outside periphery of the light-concentration reflector and the inside periphery of the primary light reflector; and a means for adjusting the distance of the light-concentration reflector from the primary reflector.
