Patent ID: 7847471

Claim:
An LED lamp, comprising: a hollow lamp housing; an optical part located at a front end of the lamp housing, the optical part comprising a plurality of light sources each being provided with at least one LED, a light reflector and an optical lens; an electrical part located at a rear end of lamp housing, the electrical part being provided with a circuit board electrically connecting with the light sources; and a heat dissipation part located between the optical part and the electrical part, the heat dissipation part comprising: a heat sink arranged in the lamp housing and comprising a plurality of fins, the lamp housing defining a plurality of air exchanging holes therein corresponding to the fins of the heat sink; a mounting seat located between the heat sink and the optical part, the mounting seat comprising a top surface facing the heat sink, an opposite bottom surface, and a plurality of sloping heat absorbing surfaces between the top surface and the bottom surface, the heat absorbing surfaces facing the heat sink and the light sources being respectively arranged on and thermally connected with the heat absorbing surfaces, heat generated by the light sources being absorbed by the mounting seat; and a heat conducting member connecting the mounting seat with the heat sink to transfer heat from the mounting seat to the fins of the heat sink, the light reflector of the optical part being located between the heat sink and the mounting seat and surrounding the heat conducting member, the light reflector forming a light reflecting surface at a front side thereof facing the light sources, the optical lens being located in front of the light reflector and the mounting seat, the light reflector and the optical lens cooperatively receiving the mounting seat and the light sources therein, light emitted by the light sources being reflected and guided by the light reflector to an outside through the optical lens.
