Background technique

In the existing electric light source technology, it is very common to use LED lamps for lighting. Various and colorful LED lamps add beautiful scenery to people's lives. Although LED lamps are a new type of lamps with composite energy-saving and environmental protection requirements, LED lamps will generate high heat when they are powered on, and the speed of heat dissipation will have an important impact on the life of LED lamps. Therefore, at present, general LED lamps use heat-conducting elements to dissipate heat. However, metal heat-conducting elements usually used for heat dissipation, because of their high density and low thermal conductivity, cannot effectively conduct heat conduction and cool down on LED lights, and often burn out normally working LED lights, causing failures. It has caused some unexpected consequences to people and brought a lot of regrets.
