Abstract
A luminaire capable of providing up-lighting when suspended from above, or mounted from below, or wall lighting when mounted as a sconce, having a longitudinally extended tapered hollow shell body which is open in the direction of intended illumination, a lamp mounting assembly, a fixture mounting assembly, and a louver assembly which is positioned between a lamp mounted in the fixture and the surface to be illuminated. The louver assembly is an integral unit having a supporting member which carries longitudinally spaced light-transmissive louvers which project from the body opening toward the illuminated surface. Each louver is formed of a partial disk which may be arcuate (e.g. semi-circular or semi-elliptical) or polygonal, and may have a beveled peripheral surface.
