With the development of the market, new energy LED street lights gradually enter our field of vision. The cooling problem of new energy LED street lights has always been a problem that plagues us. On the one hand, related instructions.

The heat dissipation problem of street lights is urgent. Only by solving this problem can the use performance of LED street lights. Heating is not only directly related to the actual lighting efficiency of LED street lights, but also because the brightness of new energy LED street lights is high, the heat is large, and it is used in a relatively harsh outdoor environment. In the design of new energy LED street lights, the power -based LED itself requires good heat dissipation, but the street lamps that are used for outdoor applications should have the necessary level of dustproof and waterproof effect (IP), and good IP protection often hinders LED heat dissipation.

To solve these two problems that conflicts with each other but must be solved, it is an important aspect of the design of street lamps. At present, the materials used in the new energy LED street radiator are basically metal materials, which are mainly based on the following three aspects: 1. Good thermal conductivity. Compared with other solid materials, metals have better thermal conductivity; 2. Easy to process. The metal ductility is good, and the high temperature is relatively stable. Various processing processes can be used; 3. Easy to obtain and the price is relatively low. Another important point is to use integrated aluminum compression of the cooling shell. New energy LED street lights usually use the design of the shell and the radiator as one to solve the LED heating problem. Generally, aluminum or aluminum alloy, copper or copper alloy and other alloys are used. Essence
