Nowadays, the application of Light-Emitting Diodes (LEDs) is constantly expanding, so the input power of LEDs must be continuously increased, but continuous light-emitting diodes will generate heat accumulation, which will reduce the luminous efficiency and cause Accelerate the temperature increase of the light-emitting diode itself. Generally, the light-emitting diode on the existing device only dissipates heat through the circuit board combined with the light-emitting diode, so that the heat generated by the light-emitting diode is not easy to dissipate, causing the light-emitting diode to overheat and damage. The light-emitting diode is installed on the circuit board, so the heat energy accumulated by the light-emitting diode may even cause the circuit board to burn out, especially the lighting equipment that uses high-brightness or ultra-high-brightness light-emitting diodes must face the quality change or life of the material caused by high heat reduced problem.
