Problems solved by technology

[0004] The purpose of the present invention is to provide a liquid-cooled heat transfer and air-cooled heat dissipation high-power LED lamp. The present invention uses liquid-cooled rapid heat transfer and air-cooled forced heat dissipation to solve the problems of rapid heat conduction and rapid heat dissipation of high-power LED chips and fluorescent materials. The problem is that the invention can actively conduct away the heat generated by chips and fluorescent materials, and has obvious heat conduction and heat dissipation effects. Liquid-cooled heat conduction plus air-cooled heat dissipation eliminates the passive heat conduction and heat dissipation aluminum materials of traditional lamps, and the volume and weight are reduced. And it is a good solution to the heat conduction and heat dissipation problems of super high-power LEDs

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...
