Custom aluminum heatsink for LED with CNC machining in Foshan Factory
Product Description
The main function is to continuously export the heat generated by the LED chip to the environment, so that the temperature of the chip remains within the required range, so as to ensure that the LED lamp can operate normally.The quality of the radiator mainly depends on the thermal resistance of the radiator, the smaller the thermal resistance, the lower the LED lamp temperature under the same conditions, the lower the LED temperature, the longer the service life of the chip will be.The heat resistance of the radiator shall include heat conductivity heat resistance and heat dissipation heat resistance.
