ABSTRACT:
A luminaire which casts a substantially rectangular pattern of light on a surface. It utilizes a lamp which has an axis of radiation and the property of emitting a disproportionately larger percentage of its luminous flux in an annulus which lies between a substantial bounding region at each end of the lamp. A reflector includes a cavity in which the lamp is placed. The reflector has a cutoff edge that forms an aperture opening from the cavity. Support means mounts the lamp in the cavity above the cutoff edge. Specular reflecting means is provided in the reflector to reflect light which is initially directed above the cutoff edge to the surface as supplementary light to fill in areas where light that is directly emitted through the aperture without reflection does not provide proper illumination to the surface.
