Abstract

An apparatus including at least one LED mounted to a printed circuit board, a reflector including at least one heat stake, and a mounting plate comprising at least one aperture for receiving the at least one heat stake. The at least one LED is positioned between the reflector and the mounting plate such that the at least one LED is held in position when the at least one heat stake is received within the at least one aperture.

Claims

1. A rearview mirror assembly for a vehicle comprising:

a mirror mounting structure for attaching to the vehicle;

a mirror supported by said mirror mounting structure; and

a lamp subassembly supported by said mirror mounting structure, said lamp subassembly comprising;

at least one LED device comprising at least one LED chip and a heat extraction element in thermal communication with said at least one LED chip; and

a thermally conductive reflector for reflecting light emitted by said at least one LED device, said thermally conductive reflector being disposed in thermal communication with said heat extraction element so as to function as a heat sink for said at least one LED chip.
