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.
