In this scheme, the heat dissipation of the scheme is to absorb the heat of the light emitting device through one end of the superconducting heat pipe, and transfer the heat to the heat sink of the lamp body in contact with the air at the other end. , because it is still multiple indirect heat dissipation, the effect is still not good

[0005] In the document of Chinese patent authorization announcement number CN2557805Y, a high-power LED lamp heat dissipation scheme is disclosed. In this scheme, the heat dissipation of the scheme is to absorb the heat of the LED through the air in the lamp body and transmit it to the lamp body heat sink in contact with the lamp body in contact with the air. It still belongs to indirect heat dissipation, and the effect is not good

[0006] In the document of Chinese patent application publication number CN1594962A, a kind of LED lamp heat dissipation scheme is disclosed. Heat dissipation, the effect is still not good

[0007] In the Chinese patent application publication number CN1605794A document, a heat dissipation scheme for LED spotlights is disclosed. In this scheme, the heat dissipation of the scheme is to absorb the heat of the LED through the air in the lamp body or the filling material and transmit it to the heat dissipation shell in contact with the air, which is still indirect heat dissipation. , still doesn't work well

[0008] In the Chinese Patent Application Publication No. CN1603679A document, a LED lamp heat dissipation scheme is disclosed, in which the heat dissipation of the scheme is that the heat of the LED (mainly the heat at the base of the LED) is transmitted to the heat dissipation plate through the circuit board and the conductive heat dissipation adhesive layer. , still indirect heat dissipation, still ineffective
