Patent ID: 7631987

Claim:
A light emitting diode lamp, comprising a heat sink, comprising a substrate and a plurality of extending arms, a slot is formed between two neighboring extending arms; and a plurality of heat dissipating fins, inserting into the corresponding slots, one of opposite sidewall surfaces of each extending arm being against one of opposite surfaces of each heat dissipating fin, each heat dissipating fin has a fin top and a fin bottom respectively protruding from a top and a bottom of the substrate, the heat dissipating fin and the top of the substrate forming an accommodation space; a socket, firmly fixed at the fin bottoms of the heat dissipating fins; a light emitting module, comprising: a heat conductor, mounted on the substrate of the heat sink; at least one light emitting diode unit, mounted on the heat conductor; a circuit board, electrically connected to the light emitting module; and two pins, electrically connected to the circuit board, wherein the two pins penetrate through the socket; a holder, inside the accommodation space opposite to the socket, and the heat dissipating fins are secured to the holder; and a lens, positioned above the light emitting diode unit and assembled inside the holder.
