[0002] Before the popularization of LED street lamps, high-pressure sodium lamps or metal halide lamps were mostly used for street lamps. Although these lamps can provide good lighting effects, they have low energy efficiency and short service life. LED technology entered the street lighting market in the early 2000s. The initial LED street lamps mainly focused on the brightness and efficiency of the light source, and the heat dissipation design was not given enough attention. With the wide application of LED technology, people began to realize the heat dissipation problem of LED lamps. During the operation of the LED light source, heat will be generated. If effective heat dissipation is not carried out, it will lead to a decrease in light efficiency and a shortening of the service life. The composition structure of an LED street lamp includes a lamp body housing, an LED light source module, a heat dissipation system, a power drive module, and an installation component, etc. In the use process of an existing LED street lamp with a heat dissipation mechanism, due to the relatively slow heat dissipation efficiency of the heat dissipation system or excessive energy waste, the function of effectively dissipating heat during the use of the LED street lamp cannot be realized. Therefore, the above technical problems need to be solved. Content of the Utility Model
