Problems solved by technology
[0002]At present, the demand for LED lighting is becoming more and more urgent. As LED lights are energy-saving green light sources, the heat dissipation problem of high-power LEDs has been paid more and more attention, because too high temperature will lead to LED luminous efficiency. Attenuation; if the waste heat generated by LED operation cannot be effectively dissipated, it will directly have a fatal impact on the life of the LED. Therefore, in recent years, the solution to the heat dissipation problem of high-power LEDs has become an important research and development topic for many related industries.

Embodiment
[0012] Example: such as figure 1 , figure 2 As shown, a LED lamp radiator includes a radiator body. The radiator body is mainly composed of a heat sink 1 and a center column 3. The heat sink 1 is uniformly fixed on the outer surface of the center column 3 in a radial shape, and the interior of the center column 3 is A cavity, the lower end of which is connected to the LED lamp mounting base 2 . When the LED lamp is working, the radiator absorbs a large amount of heat to heat up the surrounding air, so the air density decreases and moves upward, so a negative pressure appears in the center column, and the bottom of the column absorbs the cold air from the outside, realizing the exchange of cold and heat of the air and improving heat dissipation efficiency.
[0013] The radiator body of the present invention is made of aluminum alloy, which can increase the heat dissipation effect of the radiator.

Description
technical field [0001] The invention relates to a heat sink, in particular to a heat sink for an LED lamp. Background technique [0002] At present, the demand for LED lighting is becoming more and more urgent. As LED lamps are energy-saving green light sources, the heat dissipation problem of high-power LEDs has been paid more and more attention, because excessive temperature will cause LED luminous efficiency to decay; if the waste heat generated by LED operation cannot be effectively dissipated, then It will directly have a fatal impact on the life of the LED. Therefore, in recent years, the solution to the heat dissipation problem of high-power LEDs has become an important research topic for many related industries. [0003] Since the quality of the radiator depends on the thermal conductivity and heat dissipation area of its own material, improving the conduction rate and conduction path of the radiator, as well as applying a radiator made of high thermal conductivity...
