Thermally Dissipated Lighting System

摘要

A lighting system or luminaire can comprise two environmentally sealed housings. One of the housings can house one or more light emitting diodes. The other housing can house a driver for supplying electricity to the light emitting diode or diodes. The housings can be nested together. For example, one of the housings can extend partially into a cavity of the other housing. A portion of the cavity can remain unfilled when the housings are nested, to provide an air gap between the two housings. The air gap can be environmentally exposed, for example exposed to moisture when the lighting system is mounted outdoors.

主权项

1. A lighting system comprising:
a first environmentally sealed housing comprising:
a first exterior surface comprising a window;a second exterior surface that is opposite the first exterior surface and that forms a cavity; anda rim disposed peripherally relative to the cavity; a light emitting diode disposed in the first environmentally sealed housing and oriented to emit light through the window; a second environmentally sealed housing comprising:
a third exterior surface that forms a protrusion;a shoulder disposed peripherally relative to the protrusion; anda fourth exterior surface that is opposite the third exterior surface; and a light emitting diode driver disposed in the second environmentally sealed enclosure, wherein the first environmentally sealed housing and the second environmentally sealed housing are disposed adjacent one another with the shoulder adjoining the rim, the protrusion disposed in the cavity, and an air gap separating the second exterior surface from the third exterior surface.
