Self-adjusting light-emitting diode optical system

摘要

A mounting assembly for a lighting fixture includes a fixture shield and an optic housing coupled at least in part to the fixture shield and having a light-emitting surface. The assembly further includes a heat sink movably coupled to the fixture shield in an initial low position, the heat sink being self-adjusting to one or more high positions relative to the fixture shield in direct response to displacement caused by one or more objects contained within the optic housing.

1. A mounting assembly for a lighting fixture, the assembly comprising:
a fixture shield; an optic housing coupled at least in part to the fixture shield and having a light-emitting surface; and a heat sink movably coupled to the fixture shield in an initial low position, the heat sink being self-adjusting to one or more high positions relative to the fixture shield in direct response to displacement caused by one or more objects contained within the optic housing, the heat sink having a bottom surface facing toward the fixture shield and a top surface opposite the bottom surface; and a plurality of spring-loaded fasteners for coupling the heat sink to the fixture shield, each of the spring-loaded fasteners including a compression spring which applies a force against the top surface of the heat sink to adjustably press the heat sink toward the fixture shield.
