The heat dissipation problem of high-power LED floodlights limits the development of the LED lighting industry. If the heat dissipation problem cannot be solved, the temperature of the lamps will increase, which will greatly reduce the luminous efficiency. For the current LED floodlight manufacturers, how to improve the heat dissipation performance of high-power LED floodlights has become an important way to save costs.

At present, there are three main heat dissipation methods for LED floodlights, namely natural convection heat dissipation, forced heat dissipation by installing fans, heat pipe and loop heat pipe heat dissipation. The choice of LED flood light plays an important role in reducing temperature rise. Selecting LED lamp beads encapsulated by materials with high and consistent thermal conductivity can improve the internal thermal diffusivity. In addition, the wick board uses a metal substrate with high thermal conductivity and high heat dissipation, which can make the temperature distribution of the heat sink uniform, so that more and more Good cooling effect.

When the heat generated by the LED light exceeds its cooling capacity at rated power, it also uses temperature control technology to limit the temperature rise while enhancing heat dissipation. When the temperature is high, the temperature control system will appropriately reduce the output of the driver to limit and reduce the temperature; when the temperature is lowered, the original working state will be restored.

Using the above method, once the temperature rise exceeds the set control temperature, the driver will reduce the output, and properly reduce the luminous flux and power consumption of the floodlight without affecting the use, so as to avoid light decay and shortened life due to overheating.
