Problems solved by technology

For a long time, power supply damage, shortened lifespan, and accelerated light decay caused by poor heat dissipation are the primary factors restricting the rapid development of LED energy-saving lamps.
The existing common LED heat dissipation materials are mainly made of metal materials such as aluminum and copper, which have disadvantages such as cost limitations and insufficient insulation performance in actual use.
As an improvement, heat dissipation materials such as plastics and ceramics have also appeared in the prior art, and these materials cannot simultaneously meet the requirements of energy-saving LED radiator materials such as good insulation, low expansion coefficient, large thermal conductivity, good heat dissipation effect, and quality. Advantages of lightness and good mechanical properties
