What Is The Working Principle Of The LED Heat Sink?
The thermal resistance of the LED heat sink should include both thermal resistance and thermal resistance. For a certain shape of LED heat sink, the thermal conductivity is mainly related to the thermal conductivity of the heat sink material. The larger the thermal conductivity, the smaller the thermal resistance and the better the thermal conductivity. Under certain environmental conditions, the thermal resistance depends mainly on the LED. The heat dissipation area of the heat sink and the radiation coefficient of the surface material of the heat sink, the larger the heat dissipation area, the higher the radiation coefficient, the smaller the heat dissipation resistance, and the better the heat dissipation effect.

LED heat sink is a component that can quickly derive and dissipate the heat generated in the operation of the LED chip into the environment. Therefore, it is impossible to have only a certain heat dissipation area as a heat sink, and the material for manufacturing the heat sink must have a certain heat conduction. Sex, that is, to have a higher thermal conductivity, the heat generated by the chip can be continuously exported and finally dispersed into the environment; of course, for the thermal conductive material, in addition to thermal conductivity, it should have a small specific gravity, low price, and high strength. Easy to process and other features.
