LED heat dissipation technology was born in 2000. It is made of semiconductor light-emitting diodes. The working principle is electroluminescence combined with radiation. It is the most common way of heat dissipation. Aluminum heat sink fins are used as part of the housing to increase the heat dissipation area.

  The LED heat sink can be used to control the junction temperature of semiconductor devices to be less than the maximum junction temperature. Most LED heat sinks are selected for materials with high thermal conductivity. At present, the LED radiators in the electronic products at home and abroad generally use copper, aluminum, and iron. The most used is aluminum (heat conductivity 2.12W/cm·℃). The thermal conductivity of copper is high (3.85W/cm·℃), but the cost of not including aluminum is low. In some small electronic products, some of the radiators made of steel will be used, although the heat transfer of steel The conductivity is a bit poor (0.46W/cm·℃), but its cost is relatively low, so it can be used in products that are not very demanding. In most cases, the thicker the material of the LED heat sink and the larger the surface area, the better the heat dissipation effect. However, when the actual temperature of the semiconductor power device can be guaranteed to work normally, the actual temperature is less than the maximum junction temperature. Then we should choose varieties with less bulk materials as much as possible

  Generally speaking, the stability and quality of LED lamps are critical to the heat dissipation of the lamp body. The heat dissipation of high-brightness LED lamps on the market often uses natural heat dissipation, and the effect is not ideal. LED lamps made by LED light sources are composed of LEDs, heat dissipation structures, drivers, and lenses. Therefore, heat dissipation is also an important part. If the LED does not dissipate heat well, its life will be affected.
