led lighting, thus joining semiconductor "Waterproof Cooling Fan" high heat transfer efficiency of the refrigeration system consisting of modules and fins, compact and lightweight structure is conducive to high-power UVLED heat, install and work. "Waterproof Cooling Fan" single chip to the thermal resistance of the ceramic substrate, and its size depends on the chip manufacturing process.
         Elevator led lights semiconductor refrigeration cooling system work consists of two parts:
       ① "Waterproof Cooling Fan" by the temperature difference between the cooling block internal cooling heat exchanger;
         ② fin heat by convection and radiation.
