Abstract

A lighting fixture for overhead mounting to produce a generally-rectangular, outwardly and downwardly directed light illumination over a broad areal expanse. The fixture includes a pair of back-to-back arranged reflectors depending from a supporting overhead housing and defining arcuate, generally-parabolic sections flaring outwardly horizontally of one another from opposite sides of a lamp of the fixture. A refractor of polymeric organic composition overlying and protectively capping the lamp and the reflectors diffuses, distributes and directs illumination from the lamp, from the parabolic reflectors and from a reflector plate located above the reflectors to provide an expansive, essentially rectangular-beam light pattern of uniform illumination. Physically faceted upper sections constituting flattened areas of the parabolic reflectors enhance the distribution of light to ensure more even illumination patterns and eliminate 'dark' zones.
