Description

technical field [0001] The invention relates to a liquid-cooled heat transfer and air-cooled high-power LED lamp, which belongs to the technical field of high-power LED lamps. Background technique [0002] At present, with the wide application of LED lamps, the demand for high-power LEDs is increasing, and the requirements for LED power are getting higher and higher. High-power LED lamps will generate a lot of heat, so high-power LEDs on the market are generally large in size, large radiators, and heavy in weight, which cannot effectively transfer and dissipate heat. Use and installation have brought great inconvenience. The electro-optical conversion efficiency of LED is about 20%, and about 80% of the electric energy is converted into heat and dissipated, so the heat flux density at the chip is extremely high, and the chip generates a lot of heat after the chip is luminous and electrified; blue light is converted into white light through fluorescent materials. A large am...
