MODULAR, ADAPTIVE CONTROLLER FOR LIGHT FIXTURES

摘要

? controller (in enclosure 14) for releasably mounting to a light fixture (10) for selectively switching the lamps of the light fixture on and/or off. The controller includes a mount adapted for mounting the controller to the light fixture and circuitry for selectively switching the lamps of the fixture and passive and/or active temperature management. Also disclosed is a light fixture adapted for on-site assembly from component parts in any of several configurations as required to optimize the light fixture for a particular application or installation. The light fixture includes a central channel member (112), end caps (116), extensions (122) assembled to the channel member, and shields (124) that assemble either to the extensions or directly to the channel member depending upon the amount of light needed and the number of bulbs to be mounted in the fixture. The electronics for controlling the fixture, including the ballast, are mounted in the central channel and thereby isolated from the heat produced by the light bulbs mounted in the fixture.
