Description

Technical Field

[0001] The invention relates to the field of LED lamp cooling, in particular to an automatic cooling device for LED lamps. Background Art

[0002] LED, or light-emitting diode, is a new light source with low power consumption, low lifespan, small size, high brightness, low energy consumption, and no pollution. It is known as the green lighting source of the 21st century. However, due to the limitation of the light-emitting principle of LED, it cannot have good astigmatism characteristics like ordinary incandescent lamps and fluorescent lamps. There are often problems such as small lighting range and large brightness difference between the back-illuminated area and the non-illuminated area. At the same time, due to the small size of the light-emitting body, the heat is concentrated, and the packaging material does not dissipate heat well, which often leads to excessively high LED junction temperature, resulting in serious light decay and affecting the service life. Most of the existing LED lamps are arranged in a closed structure, which is more likely to cause excessive temperature, and there is no mechanism for cooling and ventilation, so the use effect is poor.
