Abstract:
1. A multiple-set heat-dissipating structure for a light emitting diode (LED) lamp for performing heat dissipation of the LED lamp, comprising: a heat-conducting base with a base plate adhering to and contacting with the LED lamp and a protruding plate extending upwardly on the base plate, an outer diameter of the protruding plate being slightly smaller than that of the base plate, the LED lamp further having a lamp cover and the heating-conducting base being combined with the lamp cover by fitting the protruding plate in an opening of the lamp cover, wherein a center of the protruding plate is provided with an accommodating hole; a plurality of heat pipes, each heat pipe having a heat-absorbing end and a heat-releasing end, the heat-absorbing end connected to the protruding base, the heat pipes including one I-shaped heat pipe with the heat-absorbing end to be received in the accommodating hole; and a plurality of heat-dissipating bodies separately formed, each heat-dissipating body having a hollow cylinder with a circular cross section to receive the heat-releasing end of each heat pipe therein and a plurality of radial heat-dissipating pieces extending from an outer periphery of the cylinder.
