Description

technical field [0001] The invention relates to a heat dissipation material, in particular to a novel LED ceramic heat dissipation material, which belongs to the technical field of LEDs. Background technique [0002] LED lamps, the full name of light-emitting diode lamps, refer to appliances that can transmit light, distribute and change the light distribution of LED light sources. With its technical characteristics of high efficiency, energy saving, longevity, and compactness, LED lamps have effectively promoted the rapid development of the environmental protection and energy saving industry. Due to the light generation characteristics of the LED, only 20% of its energy input when illuminating the device is converted into light energy, while the remaining 80% is converted into thermal energy in the junction part, thereby increasing the internal temperature. LED light-emitting products, especially LED light panels, have great heat dissipation problems. In many cases, excess...
