Abstract
A luminaire is disclosed for producing uniform rectangular or square patterns of light. The luminaire itself consists of eight, curved main reflector sections which are concentrically located about a bulb mounting location opposite the open side of the housing in which the luminaire is mounted. The main reflector sections are joined together at their edges, such that cross sections of the luminaire in planes parallel to the open side of the housing form octagons of decreasing size as the cross sections are taken at increasingly greater distances from the open side of the housing. The orientation of the main reflector sections is such that alternate points of the octagon are located in alignment with the center of the bulb placed in the center of the reflector sections and corners of the area to be illuminated. In these corners, flat secondary reflector sections, which extend part way into the luminaire, are attached to the main reflector sections to increase the concentration of light reflected from the light source in the center of the luminaire to the corners of the area to be illuminated.
