At the beginning of the 20th century, China began to use electrical appliances on a large scale. It can be said that electrical appliances are already a very common kind of thing. Although the generalization of electrical appliances has brought us a lot of convenience, it has also brought us danger. In recent years, more and more news broke, and electrical appliances caused explosions due to poor heat dissipation during use. Such news abounds, so in this article today, we will take LED lights as an example to tell you Talk about those things that the appliance dissipates heat! First, LED မီး, like all electronic components, will generate thermal energy and temperature rise during use or operation. If heat dissipation is ignored, LED lights will be burned out due to high temperature. cover custodia case iphone 11 V1704 wallpaper avengers endgame 72sN4 Second, due to the development of high-power LED technology, LED luminaires face the severe challenges of thermal management and heat dissipation design, because an increase in temperature will not only cause the brightness to decrease, but also accelerate the luminaire body and packaging when the temperature exceeds 100 degrees Material deterioration. cover custodia case iphone 11 M1532 disney wallpaper 18wC0 ထို့ကြောင့်, in addition to the heat dissipation technology of the LED package itself, the heat sink of the LED lamp is the biggest key to maintaining the life of the lamp. cover custodia case iphone 11 W7898 adventure time wallpaper 1sV9 The selection of LED heat sink is very critical. cover iphone 11 arc en ciel Let’s take a look at the selection of LED heat sink. Plastic The poor heat resistance of LED lamps is well known, which inevitably brings the problem of the life of the wick, but the plastic material is very passive in heat dissipation, and it is mostly air-cooled or even closed. cover iphone 11 danganronpa v3 Like some lamps, a plastic sleeve is added between the driver board and the aluminum heat sink to increase the reliability of the insulation, and it is also necessary to fill the heat sink with silica gel to improve the heat dissipation ability. cover iphone 11 flower power Generally, the internal temperature of this type of lamp will be 70 to 80 degrees.

And the price of plastic will be too expensive, so plastic is not suitable for LED lights Aluminum alloy Aluminum alloy is recognized as a good heat dissipation material in the manufacture of LED lamps. On the one hand is its good heat dissipation coefficient, on the other hand is its price. Aluminum alloy has good thermal conductivity, which can help LED lights to dissipate heat.

Aluminum profile heat sinks can be used for various surface treatments, with a wide variety of designs, no solder joints, strong decoration, beautiful and durable, and can meet people’s personalized requirements.
