LED street lamp is a kind of lighting tool that we commonly use now. The LED street lamp shell is to protect the role of LED street lamp. So what is the role of the LED street lamp shell to the LED street lamp? Today the 100w Street Light Housing manufacturer will answer for everyone.

Because the LED is a photoelectric device, 15% to 20% of the electrical energy is converted into light energy during the working process, and most of the remaining electrical energy is converted into thermal energy, which causes the temperature of the LED to increase. At this time, the heat dissipation of the LED street lamp housing is needed. Because the lumen output of the LED decreases as the junction temperature of the LED increases, the life of the LED decreases as the junction temperature increases. If the heat dissipation of the LED is good or not, it will directly affect the use effect and life of the street lamp.

Therefore, the quality of the LED street lamp housing is very important. Among them, LED street lamps have natural heat dissipation, forced cooling by installing fans, and heat pipe and cooling fin technology. The natural heat dissipation of the LED street lamp housing utilizes natural convection and heat radiation. The structure is reliable and easy to make waterproof, but the structural design of the lamp body itself has high requirements. The LED street lamp housing equipped with a fan for forced heat dissipation mainly uses forced convection to achieve heat dissipation. The heat dissipation speed is fast, but the cost and noise are high, and it is difficult to make it waterproof. The heat pipe and heat dissipation fin technology of the LED street lamp housing mainly uses the heat pipe to quickly conduct the heat generated by the LED to the heat dissipation fin to achieve the purpose of heat dissipation. There are no moving parts and the system is stable, but the cost is relatively high. The LED street lamp housing keeps the LED junction temperature below 70°C, ensuring stable operation of the LED for a long time under low light attenuation, improving the maintenance factor of the lamp, and saving maintenance costs. To achieve the purpose of cooling LED street lights.

The LED street light shell is the protective shell of the LED street light. If there is no LED street light shell, then the LED light can not be outdoors in the wind and rain. For many years, if the LED street light is good, then we must choose a good LED street light shell .
