As a new generation of green and environment-friendly solid lighting sources, it has become the focus of attention. It has the advantages of low power consumption, pure light color, solid state, light weight and volume. A series of advantages such as small size and environmental protection, when the LED emits light, part of the energy will be converted into heat, therefore, the temperature of the LED chip will increase, and the temperature will have a great impact on the working performance of the LED chip, and high temperature will reduce the photons emitted by the chip. , the quality of the color temperature decreases, the aging of the chip is accelerated, and the life of the device is shortened. Therefore, in order to ensure the normal operation of the LED street lamp, the heat emitted must be dissipated in time. At present, more and more high-power LED chips are used. According to data It is shown that high-power LEDs can only convert about ten to fifty percent of the input power into light energy, while the remaining eighty-five to ninety percent are converted into heat energy. Therefore, the problem of heat dissipation seems very important.

As we all know, the current LED street lights on the market use the integrated design of the radiator and the lamp housing, that is, a large number of trough cooling holes are arranged on the upper part of the lamp housing, and the heat emitted by the LED chip is driven by the natural wind. The heat dissipation holes radiate out, but the heat dissipation effect of this type of LED street light is not good, and it is more affected by the weather, especially in high temperature weather, the temperature of the air will rise, only through the natural wind cooling and heat dissipation, the heat dissipation effect is very small , thereby shortening the service life of LED street lights.
