[0002] As an excellent semiconductor light source, LED light-emitting diodes have gradually replaced traditional high-energy-consuming lamps, such as fluorescent lamps and incandescent lamps, and have gradually become popular among people due to their small size, low power consumption, long service life, and environmental protection. In our daily life; however, in the process of developing to high power, LED lighting is affected by the heat dissipation problem, which has become the main bottleneck hindering the popularization and application of high power LED technology

Since the luminous characteristics of LED determine that its operating temperature is inversely proportional to its luminous efficiency, the increase in LED temperature will reduce the luminous efficiency of high-power LEDs, accelerate the light decay of LEDs, and significantly reduce the life of LEDs.

[0003] At present, the heat dissipation technologies used for high-power LEDs at home and abroad basically adopt the following four methods: natural heat dissipation by heat sinks, forced heat dissipation by adding fans, heat dissipation by loop heat pipe technology, and heat dissipation by semiconductor cooling fins; however, the heat dissipation efficiency of natural heat dissipation by heat sinks If it is too low, the noise of forced cooling by the fan is too high, and the heat dissipation of the loop heat pipe technology can only reduce it to the ambient temperature at most. If the efficiency is greater than 1, the heat dissipation burden is large and the cooling efficiency is not high; at the same time, it is not easy to increase the density when high-power LED lights need to be densely distributed
