A light emitting diode lamp includes a heat sink, a socket, a light emitting module, a holder and a lens. The socket and the holder are respectively positioned opposite sides of the heat sink. The light emitting module is combined with the heat sink and has a light emitting diode unit. The lens is mounted on the light emitting diode unit and combined inside the holder. The heat sink includes a substrate and a plurality of heat dissipating fins. The substrate has a plurality of extending arms in a manner that a slot is formed between two neighboring extending arms. A plurality of heat dissipating fins is inserted into the corresponding slots. One of opposite sidewall surfaces of each extending arm is against one of opposite surfaces of each heat dissipating fin. Thereby, there is no need of producing a heat sink by soldering.
