Problems solved by technology

Due to the large thermal resistance of the aluminum substrate and the heat-conducting adhesive, a lot of heat cannot be dissipated in time, so the power of LED lamps, especially bulb lamps, is not too high, and can only be below 8W, because the heat dissipation cannot be solved.

Abstract

The invention discloses an LED lamp based on compound heat dissipation technology, which comprises three parts: a shell unit, a lamp group unit and a power supply unit; the shell unit uses a plastic lamp cap as a connecting body, and its upper part is connected with a metal lamp cap, and its lower part is connected with a metal lamp cap. The plastic or aluminum lamp housing is connected, and there are convection groove lamps engraved around the housing, and the outside is coated with black nano-radiation paint; the ceramic substrate of the lamp group unit and the aluminum plate are tightly welded through the silver foil of the ceramic substrate and the tin-plated layer of the aluminum plate, and the porous copper It is welded on the other side of the aluminum plate, and the LED tube is welded on the other side of the ceramic substrate. Due to the use of composite technologies such as ceramic substrates, porous copper and nano-coatings for heat dissipation, the heat dissipation methods of conduction, convection and radiation are fully utilized for effective heat dissipation, so that the power of LED lights can be made larger.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED lamp using composite heat dissipation technology. Background technique [0002] In recent years, LED has been widely used as a new light source in various fields; however, the light emission of LED needs to be driven by current, and only about 15%-25% of the electric energy input into LED can be effectively converted into light energy, which means that a 10W LED lamp Only 2W is converted into light, while the remaining 8W will be automatically converted into heat, so heat will be generated during the LED lighting process. With the increase of LED power, the impact of thermal characteristics on LED becomes more and more significant, which will not only make the life of the device decline sharply, but also seriously affect the wavelength, power, luminous flux and other parameters of LED; in addition, the current high-power LED and LED lamps basically weld the LED tube ...
