ABSTRACT:
A lighting system is designed to replace incandescent lighting by alternatively adapting existing recessed incandescent fixtures to accept more efficient lamps such as fluorescents, or using specially designed surface mount housings. In either case the invention addresses the problem of overheating of the on-board power stabilizing circuitry which almost universally occurs when an enclosed fixture designed for incandescent lamps is fitted with fluorescent replacements. Rather than installing the power stabilizer in the enclosure with the hot lamp in direct parallel to conventional incandescent mounting, the power stabilizing circuitry is physically removed from the lamp housing and isolated from it by a curtain of circulating cooler air. The preferred embodiments house these electronics in a rim or halo around the light, with the rim so produced also acting as a decorative trim element and providing limited control of the light beam in some instances.
