In many cases, we will encounter this problem, that is, when the street lamp is used, the brightness is relatively low, and the function of the whole is not very good. There is a fire failure of the street lamp, so what is the reason for the fire failure of the street lamp.

　　As for the LED street lamp, it will announce a certain amount of heat under normal operation. As for the street lamp shell, it needs to emit heat. Assuming that the heat dissipation module can not achieve good heat dissipation, it will lead to the service life and luminous performance of the LED street lamp. Now, the serious light failure of LED street lamps is caused by these factors. Another problem is that led street lamps are used outdoors. As for the disturbing factors of environment and climate, many manufacturers have made certain treatment on the street lamp shell, such as anodic treatment protection, or spraying baking paint to avoid the corrosion of acid and alkali substances.

　　The two methods also have certain defects. The service life of anodic treatment is not long, and it will oxidize and change color after a long time. If it is removed and reinstalled, it will not only take time, but also increase the protection cost. The protection cost of baking paint is low, and the protection function is also good. However, generally, baking paint has no heat dissipation function, which will not help, but will be blocked in the radiator because of heat energy, The LED luminous power is reduced, and the thermal conductive film can not really close to the substrate. The bonding surface will have a certain space, resulting in the reduction of heat dissipation power.

　　There are certain reasons for the light failure of LED street lamps, mainly because of the heat dissipation problem. As long as the whole problem is solved, we can ensure that the application time of LED street lamps is longer and the light failure problem will be solved to a certain extent. Therefore, in the process of purchasing street lamps, pay attention to the heat dissipation of street lamps to ensure the longer service life of products.
