High lumen output fluorescent lamp fixture

Abstract

An alternative lighting system luminaire to conventional high intensity discharge light fixtures such as mercury vapor, metal halide, high pressure sodium lighting fixtures includes a translucent reflector/refractor with a starburst pattern of fluorescent lights to provide both greater lumen production per watt with uplight capabilities for an even distribution of light. This system allows one-for-one fixture replacement when substituted for 400 watt metal halide and 1000 watt mercury vapor high intensity discharge lighting fixtures in design or replacement applications. The luminaire utilizes very high efficiency 'Dulux L' high lumen compact fluorescent lamps, which each are shaped like a single inverted 'U' and are a minimum of 16 inches long. The lamps extend from the base of reflector and/or refractor in a starburst pattern, wherein the lamps extend both downward and outward. The lamps are secured and powered by clamping sockets fastened to a plate, which is mounted in a range extending from at the base to approximately one fourth the distance between the base and the larger end of the reflector and/or refractor. Ballasts are located in an enclosure mounted above and outside, or are remoted from the reflector/refractor.
