The heat dissipation methods of LED floodlights mainly include natural convection heat dissipation, forced heat dissipation by adding fans, heat pipe and loop heat pipe heat dissipation, etc. The choice of LED modules also plays a key role in reducing temperature rise. Choosing LED lamp beads encapsulated by a material with high thermal conductivity and consistent material can improve the internal thermal diffusivity. However, a metal substrate with high thermal conductivity and high heat dissipation is used as the wick plate to make the temperature distribution of the heat sink uniform, so that the heat dissipation effect can be exerted greatly.

        LED floodlights work at rated power, and when the heat generated exceeds its heat dissipation capacity, it is necessary to use temperature control technology to limit temperature rise while enhancing heat dissipation. When the temperature is high, the temperature control system will start to work, and the output of the driver will be appropriately reduced to achieve the purpose of limiting and reducing the temperature rise; when the temperature drops, it will resume the original working state.

Using the above method, once the temperature rises above the set control temperature, the driver will reduce the output, without affecting its use, appropriately reducing the luminous flux and power consumption of the LED lamp to avoid overheating. Caused by the problems of LED projection light decay and shortened service life.
