Abstract:
1. An illumination system for projecting a beam of light, comprising: a concave reflector system configured to be substantially symmetrical about a longitudinal axis wherein the reflector has a parabolic front section and a spherical rear section joined together near the intersection of a plane passing through the focal point of the parabolic front reflector section and just behind the focal point of the spherical rear reflector section: an incandescent lamp with the approximate center of the light source placed at the focal point of the front parabolic reflector section and just behind the focal point of the rear spherical reflector section: a lens located at an open end of the front reflector section wherein a substantial portion of the light emitted by the lamp impinges on, and is redirected by, the reflector system to project a beam of light substantially parallel with the longitudinal axis of the reflector system.
