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.

Luminaire having main and secondary reflector sections

A cut-off floodlight of the type having a straight light line, a reflector surface in a housing, and a light-emitting opening, and characterized by a reflector surface with a major portion parallel to the light line including a parabolic section on one side of the light line with its focus at and its vertex behind and to said one side of the light line to establish a main beam direction at an acute angle to the opening plane, and an opposite section on the other side of the light line to reflect light therefrom past the light line onto the parabolic section so its secondary reflection off the parabolic section will be close to the main beam direction.

Floodlight with improved reflector system

A 'wall-wash' lighting fixture is mounted on the ceiling along the top of a wall to be provided with a substantially uniform illumination downwardly from the fixture. An elongated fluorescent bulb is used as the source of light; and the reflector is comprised of at least a central section and two shorter end sections. The cross-section of the central section of the reflector differs from the cross-section of the end sections in a manner to cause greater amounts of light to be reflected a greater distance downwardly on the wall from the center section than from the end sections. This compensates for the non-uniform light intensity from the fluorescent bulb, and results in a more uniform illumination of the wall below the fixture.
