Problems solved by technology

At present, the structure selected for the heat sink of the LED street light source is often a lot of heat sink structures erected on the back of a large aluminum plate. This structure has poor natural convection heat dissipation performance, and is not suitable for power supply heat dissipation and rainproof. At the same time, it causes damage to the LED chip. The waterproof and moisture-proof structure is complicated, which increases the weight of the entire street lamp and increases the cost

Description

technical field [0001] The invention relates to a cooling system, in particular to a cooling system for LED street lamps. Background technique [0002] Due to the characteristics of energy saving, long life and easy maintenance of LED light sources, LED lighting technology has been continuously developed in recent years. But for high-power LED lamps, one of the most critical issues is the heat dissipation of LED lighting. The quality of LED heat dissipation is very important to the performance of the whole lamp. If the heat cannot be dissipated, it will accelerate the aging of the LED chip, light decay and color shift, shorten the life of the LED, and reduce the light efficiency of the lamp. Therefore, The heat dissipation problem of LED lamps determines the life of the lamps. [0003] To solve the heat dissipation of LED lamps is to reduce the temperature of LED lamps themselves. The heat sink is a device used to conduct and release heat. According to different heat diss...
