The function and working principle of Turned LED heat sink are introduced

The main function of Turned LED heat sink is to continuously export the heat generated in the work of LED chip and send it to the environment, so that the temperature of the chip is kept within the required range, so as to ensure the normal operation of LED lamp. The quality of the radiator mainly depends on the thermal resistance of the radiator, the smaller the thermal resistance, the lower the LED junction temperature under the same conditions, the lower the LED junction temperature, the longer the service life of the chip.

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

Therefore, the LED lamp radiator must have a certain heat dissipation area, and the material making the radiator must have a certain thermal conductivity and high thermal radiation coefficient; In addition, the thermal conductivity material itself should also have the characteristics of light weight, easy processing and low price.
