There are several cooling methods for solar street light

The height of normal solar street light is about 6-12m. It is mainly divided into single-arm solar street light and double-arm solar street light. In terms of design, a problem that is ignored by many solar street light manufacturers is the heat dissipation of lamps, so we solar street light. When designing street lamps, light manufacturers must pay more attention to the radiators of lamps. In the popular sense, the heat dissipation methods of LED street lamps are divided into two types: 1. Passive heat dissipation: The heat generated by the LED street lamps is dissipated through the natural convection between the surface of the lamp body of the LED street lamps and the air. 2. Active heat dissipation mainly uses water cooling and fans to increase the air flow speed on the surface of the radiator to take away the heat on the heat sink and improve the heat dissipation efficiency. According to the subdivision performance, there are mainly: natural convection heat dissipation, forced heat dissipation by installing fans, heat pipe and loop heat pipe heat dissipation, etc. The forced cooling method of installing a fan is complicated and has low reliability, and the heat dissipation method of heat pipe and loop heat pipe is expensive. The street light has the advantages of outdoor use at night, the heat dissipation surface is located on the side, and the body size is less restricted, which is conducive to natural convection heat dissipation of the air, so solar street light recommends choosing the natural convection heat dissipation method as much as possible.
