摘要： A multi-faceted light reflector has a reflecting surface with a plurality of adjacent facets, a light source placed in a predetermined spatial relationship to the reflecting surface, and an image surface placed in a predetermined spatial relationship to the light source and the reflecting surface. At least one of said facets has a differentially tilted parabolic cross section. The differentially tilted parabolic facet has a continuous and smooth surface with a focal axis having an angle of inclination with respect to the horizontal image surface that changes along the length of the facet.
