Aluminum high bay light fixture having plurality of housings dissipating heat from light emitting elements
First Claim
1. A lighting fixture, comprising:
- a plurality of light emitting elements;
a primary housing in thermal contact with said plurality of light emitting elements, wherein said primary housing dissipates at least some heat produced by said plurality of light emitting elements, said primary housing comprising slots or openings configured to allow at least some light from said plurality of light emitting elements to emit in a direction opposite the majority of light emitted from said plurality of light emitting elements; and
a heat transfer device in thermal contact with said plurality of light emitting elements, wherein said heat transfer device transmits at least some heat produced by said plurality of light emitting elements.

Abstract
Aluminum high bay lighting fixtures a primary housing; at least one secondary housing partially surrounding a primary housing; a plurality of light emitting elements in thermal contact with the primary housing; a heat spreader plate in thermal contact with the light emitting elements and the primary and secondary housings. At least one of the primary and secondary housings include openings to help dissipate heat from the light source and/or allow at least some of the light from the light emitting elements to be outputted in a direction opposite the main light emitting direction. The shortest distance from a distal end of the primary housing to the light sources is greater than the shortest distance from a distal end of the secondary housing to the light sources.
