Light emitting diode troffer door assembly

摘要

A troffer door assembly having a heat conductive frame assembly, a lens member and a light emitting diode (LED) assembly having a rigid heat conductive brace member, wherein the rigid brace member is affixed to the frame assembly such that the rigidity of the frame assembly is increased and such that heat is passed from the rigid brace member to the frame assembly. Hinge members and latch members are positioned in exterior slots on the frame assembly such that the location of the hinge members and latch members can be adjusted. In this manner installed troffer light fixtures can be retrofitted by replacing the installed troffer door with the troffer door assembly as described.

主权项

1. A troffer door assembly comprising:
a peripheral frame assembly comprising frame members composed of a heat conductive material; a lens member retained within said peripheral frame assembly; a light emitting diode (LED) light bar assembly comprising an array of LEDs and a rigid brace member, said rigid brace member composed of a heat conductive material such that said rigid brace member functions as a heat sink for heat produced by said LEDs; wherein said rigid brace member is connected to at least two of said frame members such that said rigid brace member increases the rigidity of said frame assembly and such that heat is passed from said rigid brace member to said frame assembly such that said frame assembly also functions as a heat sink for heat produced by said LEDs, and wherein at least one frame member includes an elongated channel provided in an exterior facing surface of the frame member, wherein the channel extends the entire length of the frame member, and wherein the channel is configured to adjustably receive at least one of a latch member and a hinge member.
