Problems solved by technology

[0002] Due to the characteristics of energy saving, good applicability, short response time, and environmental protection, LED lights have been used in mobile phones, table lamps, home appliances and other daily household appliances and machinery production, but their prices are relatively high. The rapid expansion and prolonging the service life have also become an urgent problem to be solved
[0003] LED lights still have a certain amount of heat during use, and failure to dissipate heat in time is an important reason for shortening the life of LED lights
In order to solve the problem that the luminous efficiency of the lamp is affected by the heat generated during the use of the lamp and the service life of the lamp is shortened, the current method used is to coat a layer of heat-dissipating paint on the lamp, but the heat dissipation effect of the existing heat-dissipating paint has yet to be solved. improve
