Abstract

The invention relates to an air-cooled and heat-dissipating LED downlight. A number of air guiding tubes are fixedly installed on the light-transmitting surface cover and the bracket of the fixing plate. One end of the air guide located in the rear casing is connected through a hose, and the air guide is trumpet-shaped. After the air enters the air guide, the radius of the end connecting the air guide and the hose is smaller than the radius of the end that communicates with the outside world. When the air flow enters the hose from the air guide tube, the flow velocity and air pressure increase, which increases the air flow in the hose, and the cooling air in the hose takes away the heat in the inner cavity of the rear shell, thereby increasing the air flow at the hose. The heat conduction speed improves the heat dissipation efficiency of the inner cavity of the rear shell; after the air flow in the hose absorbs a large amount of heat, the air pressure in the hose increases, and the hot air is discharged from the air guide tubes at both ends, and then circulates to realize heat dissipation.

Description

technical field [0001] The invention relates to the technical field of lighting tools, in particular to an air-cooled and heat-dissipating LED downlight. Background technique [0002] With the maturity of LED technology, downlights began to use LED downlights. LED downlights include a rear shell, a face shell, a light-transmitting cover, a power module and an LED chip. It is fixed in the middle of the face shell, and the LED chip is fixed on the rear shell. The light emitted by the LED chip is irradiated through the light-transmitting cover. The LED chip needs a power module to provide power for it. During the use of LED downlights, a large amount of heat will be generated in a short period of time, while the downlights are mainly installed in the ceiling and the top wall, the air flow in the ceiling and the top wall is weak, and the heat generated by the downlights spreads outwards The speed is slower, the heat dissipation effect of the downlight is not good, it is easy to...
