The height of normal Modular LED Street Light is about 6-12m, which is mainly divided into single-arm LED street lamps and double-arm LED street lamps. One problem that many LED street lamp manufacturers neglect in design is the heat dissipation of lamps, so we design street lamps for LED street lamps manufacturers. At the time, we must pay more attention to the radiator of the luminaire.
Simply speaking, the cooling methods of led street lights are divided into two types:
1. Passive heat dissipation: Through the natural convection of the surface of the lamp body of the led street lamp and the air, the heat generated by the LED street lamp is dissipated.
2, active heat dissipation is mainly through the water cooling, the fan increases the air flow speed on the surface of the radiator to take away the heat on the heat sink to improve the heat dissipation efficiency.
According to the subdivision performance, there are mainly: natural convection heat dissipation, added fan forced cooling, heat pipe and loop heat pipe cooling. Adding a fan to force the heat dissipation system is complicated, the reliability is low, and the heat pipe and the loop heat pipe heat dissipation method are high in cost. The street lamp has the advantages of outdoor nighttime use, the heat dissipation surface is located on the side and the body shape is restricted, which is beneficial to the natural convection heat dissipation of the air. Therefore, it is recommended to select the Economical LED Street Light with natural convection heat dissipation mode as much as possible.
