US 7,465,063 B2 · Adjustable track lighting system adapted to support multiple types of light sources

Abstract

A fixture for lamps used for portable and temporary applications has an elongated rail with a central channel, preferably with holes spaced along the channel bottom wall. Adapter bases are fit and fixed to the rail to support various types of light sources. In the case of a fluorescent lamp, each adapter base has one or more spring clamps into which a fluorescent lamp tube can be snapped and for other types of light sources the appropriate types of sockets and/or clamps, brackets or supports are provided. A wiring harness can be attached to the rail and secured by clips, clamps or holders attached to adapter bases along the rail. The rail with its attached light source or sources preferably has a flat back so that it can be mounted either permanently or temporarily to a flat surface by suitable fasteners or suspended from a ceiling or other elevated structure by a suitable tether.
