The main role of LED heatsink What is the working principle of LED heatsink?

The main function of the LED heat sink are 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 maintained within the required range , thereby ensuring that the LED lamp can work normally . The quality of the LED heatsink is mainly determined by the thermal resistance of the heat sink . The smaller the thermal resistance , the lower the LED lamp junction temperature under the same conditions , the lower the LED junction temperature , and the longer the chip’s service life . Therefore , the LED lamp radiator must have a certain heat dissipation area . At the same time , the material for making the radiator must have a certain thermal conductivity and a high thermal emissivity . In addition , the thermal conductive material should also have a light weight , easy processing , and low price . Features The thermal resistance of the LED heat sink should include thermal resistance and thermal resistance . For a certain shape of the LED heat sink , the thermal resistance are mainly related to the thermal conductivity of the heat sink material . The larger the thermal conductivity , the smaller the thermal resistance , and the better the thermal conductivity . Under certain environmental conditions , the thermal resistance mainly depends on the LED . Radiator cool area and radiator surface material emissivity , the greater the heat dissipation area , the higher the radiation coefficient , the smaller the thermal resistance , the better the cool effect . The so-called LED heatsink is a component that can quickly derive and dissipate the heat generated in the operation of the LED chip into the environment . Therefore , it is not enough to have a certain heat dissipation area as a heat sink , and the material for making the heat sink must have a certain degree of heat conduction . Sex , that is , to have a high thermal conductivity , in order to continue to export the heat generated by the chip , and ultimately dispersed to the environment ; of course , for the thermal conductivity of materials , in addition to thermal conductivity , but also should have a small proportion , low price , high strength , easy processing and other characteristics .
