The main function of the LED heat sink is to continuously derive and dissipate the heat generated by the operation of the LED chip to the environment, so that the temperature of the chip is kept within the required range, thereby ensuring that the LED lamp can work normally.
The quality of the LED heat sink depends mainly on the thermal resistance of the heat sink. The smaller the thermal resistance, the lower the junction temperature of the LED light under the same conditions, and the lower the junction temperature of the LED, the longer the life of the chip will be.
Therefore, the LED lamp heat sink must have a certain heat dissipation area, and the material of the heat sink must have a certain thermal conductivity and a high heat radiation coefficient; in addition, the heat conductive material should be light weight, easy processing, and low price.
