Patent ID: 7494248

Claim:
A heat-dissipating structure for a light emitting diode (LED) lamp, the heat-dissipating structure being mounted on the LED lamp, comprising: a heat-dissipating base for contacting with a heat source of the LED lamp; a heat-dissipating body made by aluminum extrusion and positioned above the heat-dissipating base, the heat-dissipating body having an outer cylinder formed in a hollow cylinder, an inside surface of the outer cylinder being formed with a plurality of axial accommodating grooves, wherein an outside surface of the outer cylinder of the heat-dissipating body is formed outwardly with a plurality of shorter radial heat-dissipating fins, and the inside surface of the outer cylinder is formed inwardly between the axial accommodating grooves with a plurality of longer radial heat-dissipating fins; and a plurality of heat pipes, each heat pipe including a horizontal section to be heated and fixed on a surface of the heat-dissipating base and a straight condensed end vertically extended from the horizontal section to be inserted in the accommodating groove of the heat-dissipating body.
