Lighting assemblies, methods of installing same, and methods of replacing lights

摘要

A lighting assembly comprising a light engine housing, a circuit board, a heat transfer material, an electrically conductive leg and a solid state light emitter. The emitter is in contact with a first end of the leg. The leg extends through the circuit board. A second end of the leg extends into the heat transfer material. Also, a lighting assembly as described above, which further comprises a fixture housing, in which the heat transfer material is in contact with the light engine housing and the light engine housing is connected to the fixture housing. In addition, a method of installing a lighting assembly, comprising connecting an electrical conductor and inserting the lighting assembly through a hole in a construction element such that clips attached to a fixture housing engage the construction element. Also, a method of changing a light emitter in a lighting assembly.

主权项

1. A lighting assembly, comprising:
a fight engine housing; a circuit board; a heat transfer material; at least a first electrically conductive leg; and at least a first solid state light emitter, said first solid state light emitter in contact with a first end of said first electrically conductive leg, said heat transfer material in contact with said light engine housing, said light engine housing having at least a first surface and a second surface, at least a portion of said first surface exposed to an exterior of said lighting assembly, a recess defined by said second surface of said light engine housing, a first surface of said circuit board in contact with a portion of said second surface of said light engine housing that extends around a periphery of said recess, said heat transfer material completely filling said recess between said light engine housing and said first surface of said circuit board, said first electrically conductive leg extending through said circuit board, a second end of said first electrically conductive leg extending (1) toward said portion of said light engine housing which is exposed to an exterior of said lighting assembly and (2) into said heat transfer material.
