ABSTRACT:
An LED lamp (10) having a substantially concave heat sink (12) having a raised, frusto-conical center (14) surrounded by an outer rim (16). The heat sink (12) is preferably aluminum or other metal and at least the frusto-conical center preferably has a reflective coating. To further aid in heat removal the outer rim (16) can be provided with a plurality of apertures (16a). A side-emitting LED (18) is mounted on the frusto-conical center (14). A cover (26) is fixed to the outer surface (22) and defines a volume (28) between the frusto-conical center (14) and the cover (26). A circuit (30) is located within the volume (28) and an electrical connection (32) provides connection to the LED (18). In another embodiment a cover (26a) is provided with studs (54) and a reflector (42a) is provided with studs (56) that engage barbs (50) formed in a heat sink (12a).
