ABSTRACT:
A heat-dissipating structure for a LED lamp includes a heat-dissipating base, a heat-dissipating body and a plurality of heat pipes. The heat-dissipating body has an outer cylinder formed into a hollow cylinder. The inside surface of the outer cylinder is provided with a plurality of accommodating grooves. The condensed ends of the plurality of heat pipes are inserted into the accommodating grooves. The end to be heated of the heat pipe is adhered to the heat-dissipating base. Further, the inside surface and the outside surface of the outer cylinder are formed with a plurality of heat-dissipating fins made by aluminum extrusion, so that the heat pipes are encircled by the heat-dissipating fins. In this way, the heat can be conducted by the plurality of heat pipes so as to increase the total contacting area. Thus, the heat can be rapidly conducted to the outer cylinder. Further, the heat can be rapidly dissipated to the outside by the heat-dissipating fins, thereby to substantially increase the efficiency in the heat dissipation.
