In the process of producing Triproof light, what are the general heat dissipation methods? The correct heat dissipation method of Triproof light is very important, because it will affect the use and life of the lamp.
The heat dissipation methods can be generally divided into the following types: natural convection heat dissipation, forced heat dissipation by installing fans, heat pipe and loop heat pipe heat dissipation, etc. The installation of fan forced cooling system is more complicated and the reliability is relatively low, while the cost of heat pipe and loop heat pipe cooling method is relatively high.
Because Triproof light has the advantages of outdoor use at night, the heat dissipation surface is located on the side and the body size is limited, it is conducive to the natural convection heat of the circulating fan air. Therefore, the heat dissipation method of Triproof light should choose natural convection heat dissipation as much as possible.
The heat dissipation technology of Triproof light is generally used in the form of a heat conduction plate. A copper plate about 5mm thick is actually an average temperature plate, and then the heat source needs to be averaged out; therefore, a heat sink is added to dissipate heat. But the weight is too big. Many Triproof lights now use pin-shaped heat sinks. This heat dissipation efficiency is much higher than that of traditional chip heat sinks, which can make the LED junction temperature lower than that of ordinary heat sinks by more than 15 °C It is better than the radiator of ordinary aluminum profile, and it has also improved in weight and volume.
