Abstract
Disclosed is a multi-faceted light reflector and a method of manufacturing the reflector. Planar facets are arranged in tiers, or in some other order, tangent to the surface of a spheroid to form the reflector. The size and location of the facets are correlated to the size and location of the illuminated plane. A light source is located at one focus and the illuminated plane is located at the other focus where the illuminated plane is perpendicular to the major axis of the spheroid. The facets are dimensioned and positioned so that substantially all of the reflected light from the light source is reflected to a preselected area on the illuminated plane. The method of manufacture includes calculating the coordinates for each facet, forming a convex die from the calculated coordinates, and molding the concave reflector from the convex die thus formed.
