Patent ID: 8342709

Claim:
A light emitting diode (LED) module comprising: an LED circuit board comprising at least one LED chip; a reflective surface disposed with respect to said at least one LED chip to direct light emitted from said at least one LED chip toward an axis A extending away from and substantially perpendicular to a plane containing the LED circuit board, and a heat sink formed of heat transmitting material and comprising: a mounting surface for accommodating said LED circuit board thereon to dissipate heat from the at least one LED chip, and a heat dissipation portion extending away from said mounting surface and comprising an engaging portion for attachment to a carrier plate such that at least one of said plane of said LED circuit board and a plane of said mounting surface of said heat sink is not parallel to a local plane of said carrier plate immediately adjacent to said LED circuit board, wherein said engaging portion comprises a plurality of recesses for selectively receiving an edge of an opening in said carrier plate when said heat dissipation portion is disposed within said opening to vary an angle of said plane of said mounting surface with respect to said local plane of said carrier plate to adjust the direction of light emitted from said LED module.
