The main function of the LED radiator is to continuously export and dissipate the heat generated during the operation of the LED chip to the environment, so that the temperature of the chip is kept within the required range, so as to ensure that the LED lamp can work normally. The quality of LED radiator mainly depends on the thermal resistance of the radiator. The smaller the thermal resistance, the lower the junction temperature of the LED lamp under the same conditions, the lower the junction temperature of the LED, and the longer the chip's service life. Therefore, the LED lamp radiator must have a certain heat dissipation area, and the material used to make the radiator must have a certain thermal conductivity and a high thermal radiation coefficient; in addition, the thermal conductive material itself should also have light weight, easy processing, and low price. Features.

What is the working principle of LED heat sink?

The thermal resistance of an LED radiator should include two parts: thermal resistance and thermal resistance. For a certain shape of LED radiator, the thermal resistance is mainly related to the thermal conductivity of the radiator material. The larger the thermal conductivity, the smaller the thermal resistance and the better the thermal conductivity; under certain environmental conditions, the thermal resistance of heat dissipation mainly depends on the LED The heat dissipation area of the radiator and the emissivity coefficient of the surface material of the radiator, the larger the heat dissipation area, the higher the emissivity, the smaller the heat dissipation resistance, and the better the heat dissipation effect.

The so-called LED heat sink is a component that can quickly export the heat generated by the LED chip and dissipate it to the environment. Therefore, as a heat sink, it is not enough to have a certain heat dissipation area. The material used to make the heat sink must have a certain amount of heat conduction. Performance, that is, to have a high thermal conductivity, in order to continuously export the heat generated by the chip, and finally dissipate it to the environment; of course, for thermal conductivity materials, in addition to thermal conductivity, it should also have a small specific gravity, low price, and high strength. , Easy to process and other features.
