Abstract:
1. An LED lamp assembly comprising: a planar circuit board having a substantially greater length and width than thickness, and having a first major side and a second major side; at least one LED mounted on one of said major sides of the circuit board; an electrical coupling extending from an end of the circuit board; electrical circuitry supported on the circuit board and coupling the at least one LED to the electrical coupling; a first heat sink having a planar face sized and shaped to substantially span and fit side by side to said first major side of the circuit board, the heat sink including recesses or openings of sufficient size and shape to mechanically accommodate any adjacent electrical components formed on the circuit board, and including at least one recess receiving the at least one LED and permitting the transmission of light from the at least one LED to the exterior of the lamp assembly, the planar side of the first heat sink being mechanically positioned to be in close thermal contact with said first major side of the circuit board; a second heat sink mechanically coupled to the second major side of the circuit board, the first and second heat sinks being riveted one to the other to press against the circuit board disposed intermediate said first and second heat sinks; the circuit board and first and second heat sinks forming a circuit board and heat sink assembly defining an axially extending body having substantially greater length and width than thickness, the electrical coupling extending beyond the periphery of the first heat sink exposed for electrical connection; and a base mechanically coupled to the circuit board and heat sink assembly, and having at least one latching face for mechanically coupling the lamp assembly in a lamp socket.
