LED Bulbs with PC Aluminum heat sink

For cheap LED panel light, the PC aluminum heat sink plays an important role in sinking the LED chip heat generated work constantly to export and distribute to the environment, so that the chip temperature is maintained within the range required to ensure LED lights to work properly. Whether the Aluminum heat sink of LED light bulbs for home is good or bad depends on the heat sink thermal resistance. The lower the LED junction temperature is, the longer chip life will be. The thermal resistance of the aluminum heat sink used in LED light bulbs for home should include two kinds of resistances. They are thermal resistance and heat resistance. For the heat sink of certain shape, the thermal resistance is mainly related to the thermal conductivity and the heat sink material. The greater the thermal conductivity is, the smaller thermal resistance is.

Under certain environmental conditions, the heat radiation depends on the emissivity of the surface of the material and the heat sink cooling area. If the cooling area is large, the radiation coefficient will be high, thermal resistance will be smaller and the cooling effect will be good. Therefore, heat sink gu10 LED bulbs wholesale for home must have large radiating area. Heat sink material must have a certain degree of thermal conductivity and high coefficient of thermal radiation. In addition, the thermal conductivity of the material itself should also have light weight, easy processing and low price features.

In LED home lighting, the important heat sink of LED light bulbs for home can be made of many kinds of materials. Common materials typically include three categories. They are metal materials, inorganic non-metallic materials and polymer materials. Polymer materials include plastics, rubber, chemical fibers. Thermally conductive materials are typically metals and some are inorganic and non-metallic materials. In common metals, the thermal conductivity of aluminum and copper is relatively high. That is why LED bulbs with PC Aluminum heat sink for buy LED flat panel light are popular.
