Patent ID: 7841753

Claim:
An LED illumination device, comprising: an optical section at a front end thereof, comprising at least one LED and a light output housing therearound; an electrical section at a rear end of the LED illumination device, electrically connecting with the at least one LED; and a heat dissipation section between the optical section and the electrical section comprising: at least one L-shaped heat pipe comprising an evaporation section and a condensation section substantially perpendicular to the evaporation section; a heat sink receiving the condensation sections of the at least one heat pipe; and at least one mounting seat attaching to the evaporation section of the at least one heat pipe, the at least one LED thermally connecting with the evaporation section of the at least one heat pipe via the at least one mounting seat; wherein the heat dissipation section further comprises a frame supporting the heat sink, and a holder mechanically connecting the heat dissipation section with the electrical section, the frame comprising a base and a plurality of arms extending backwardly and axially therefrom, wherein the arms are fixed on the holder, and the at least one heat pipe, the heat sink and the at least one mounting seat are received in a space cooperatively defined by the base, the arms and the holder; and wherein the heat sink defines a plurality of latching grooves at an outer circumferential surface thereof, wherein the arms are inserted into the latching grooves, respectively.
