Abstract
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.
