In recent years, LED lights have gradually replaced the lamps with low lighting lights such as incandescent lamps and solar lights, because LED lights saves more than other types of lights at the same time. But there is also a problem with LED lights that requires heat dissipation. LED components are more sensitive to temperature changes. They continue to light up LED lights at high temperatures. It is prone to reduce power, yellow, and beads falling off, which will affect the life of the lights. Therefore, the effect of using the LED lights that has been used for a long time will become worse at high temperature.
The LED lamp shell is made of aluminum alloy material. Considering the heat dissipation problem. Metal silver and copper are the best heating materials. Aluminum is second. Pure aluminum is too soft, aluminum alloy is good for molding, and the hardness is relatively high. Thermal conductivity is second only to silver and copper. Therefore, aluminum alloy has become the best choice for LED shells.
Because LED lights have high heat dissipation requirements, the LED lamp shell is generally designed with the cooling function. A lot of deep teeth are added outside the LED light shell, which greatly increases the surface area of the aluminum shell and increases thermal conductivity.
