[0002] At present, the heat dissipation problem of high-power LED lamps is still very prominent. In the Chinese patent 201010142676.6 "A Heat Dissipation Head and Manufacturing Method for High-Power LED Light Bulbs" that I applied for, it is proposed to inject a heat-conducting medium into the wick of a closed high-power LED lamp Strengthen heat conduction, and according to the power of LED lamps, install multi-layer heat sinks in the heat dissipation section to meet the heat dissipation of high-power LED lamps; but the manufacturing method only involves welding and adhesive bonding, not mechanical manufacturing processes; in view of the above shortcomings , the present invention uses an aluminum alloy material with strong machinability and good economy to manufacture a high-power LED lamp
