Do you know what the speed of the aluminum alloy LED lamp radiator is related to? Only by understanding this, we can know how to judge the quality of the radiator. Here are some reasons for the cooling speed of the aluminum alloy radiator.

Reasons for the cooling speed of aluminum alloy LED lamp radiator

First of all, let’s talk about its working principle, which is to use the LED chip to generate heat when it is working and dissipate it into the surrounding environment to keep the temperature of the week within the range of its own needs to ensure the normal lighting of the LED lamp. And its heat dissipation speed is determined by its thermal resistance. The thermal resistance is large. At the same time, the junction temperature is high, and on the contrary, it is low. The higher the junction temperature, the shorter the life of the chip, and the longer the life. The thermal resistance is related to heat conduction and heat dissipation.

So let’s talk about some of the related factors of the heat dissipation of the aluminum alloy LED lamp radiator, that is, the heat radiation area and the radiation coefficient of the surface material of the radiator. Theoretically, the larger the heat dissipation area and the higher the radiation coefficient, the lower the heat dissipation resistance, and the better the heat dissipation of the radiator. Otherwise, heat dissipation is not good. The second is thermal conductivity. The thermal conductivity is mainly determined by the thermal conductivity coefficient. The greater the thermal conductivity, the smaller the thermal conductivity, the better the thermal conductivity, and the better the thermal conductivity. Therefore, when choosing a product, we can also pass through the thermal conductivity to determine the speed of the heat dissipation of a product.

Through the above explanation, we can know that a good aluminum alloy LED lamp radiator needs a certain heat dissipation area, the radiation coefficient of the manufacturing material is high, and the thermal conductivity is also large so that the heat dissipation effect is good. Moreover, the production materials should also have the advantages of corrosion resistance, easy plasticity, and low density, so that they can make the good products they want.
