As municipal authorities seek ways to reduce operating costs, many are paying attention to the electricity consumption of their streetlight infrastructure. The main market is to renovate existing street lights and replace low efficiency light sources such as low and high voltage sodium and metal halides with LED lights.
Why the streetlight need heat sink?
The temperature of the heat sink for fully lit LED bulbs is about 60 ° C-100 ° C. If such a high temperature is not evacuated in time, it will affect the spectrum and lifespan of the LED light.
However, if the light bulb is designed properly, it can lower the temperature of electronic devices by at least 10 ° C-30 ° C compared to the temperature of the heat sink. Therefore, the temperature of the radiator can even comfortably reach 60 ° C-80 ° C for 90 ° C LED bulbs, both of which are much lower than the rated temperature of electronic components.
LED street light heatsink is a heat exchanger that absorbs the heat generated by LED modules and dissipates the heat energy into the ambient air. The spectral performance, lumen output, and lifespan of LEDs are closely related to their operating temperature. That's why the heat sink is one of the most important components of LED lighting equipment.
Street light heatsink is a metal block placed inside a street lamp. The radiator absorbs the heat generated by LED street lights and radiates it back into the surrounding air. This ensures that the junction temperature remains relatively stable and at the optimal temperature. This can prevent overheating and improve the overall lifespan of LED street lights.
The street lamp LED radiator is designed specifically for the outdoor lighting "retrofit" market, using lightweight and high thermal conductivity aluminum radiators to achieve maximum heat transfer. Multiple and high fins can increase the heat dissipation surface area, increase contact with air, and accelerate the heat dissipation effect.
