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.

摘要： An illuminator for use with a light source having a light distribution pattern within a solid angle of 2.pi. steradians. The light source comprises or includes a series of LED's or light pipes positioned at or near a focal point of a reflective surface and inclined at an angle to a focal axis of the reflective surface such that all of the light from the light source is collected and distributed by the reflective surface. Whereby the reflective surface is optimized to confine the light output only to the required photometric zones thus maximizing the efficiency of the illuminator.

摘要： A illuminator for use on a vehicle utilizing light from a remote light source. A semi-paraboloidal reflector collects and collimates light from the remote light source which is transmitted to the semi-paraboloidal reflector through a light guide, such as a fiber optic light pipe. Light from the reflector is reflected outward through a plurality of reflective facets to form a light beam.
