[0002] Direct-down LED high bay light is a kind of lighting equipment used in factories, mines and other environments. When in use, the light is hung on a high place, and the light emitted by the horizontally arranged LED light board is used for lighting. The industrial and mining lamp is called the direct type LED industrial and mining lamp. It has the advantages of energy saving, environmental protection, firm structure, and no ultraviolet radiation. All of them are converted into heat energy, causing the temperature of LED lamps to rise. If the heat cannot be dissipated in time, it will seriously affect the service life of LED high bay lights, especially for high-power LED high bay lights. The phenomenon that the heat cannot be dissipated in time and the light effect is attenuated

[0003] Most of the LED industrial and mining lamps in the prior art adopt a structure in which the heat dissipation profile is directly connected to the LED lamp panel. Although this structure is simple, due to the limited volume of the industrial and mining lamp, the heat dissipation area is small and the heat dissipation effect is not good. After a long time of use, the same There will be a phenomenon of light efficiency attenuation. In addition, the Chinese utility model patent ZL201020640118.8 discloses a LED high bay lamp, which is also an improvement for the heat dissipation problem of the current LED high bay lamp. It fixes the heat dissipation substrate on the upper surface of the LED lamp board , and then fix a plurality of heat dissipation pipes on the upper surface of the heat dissipation substrate, and the upper ends of these heat dissipation pipes extend into the heat dissipation fins to dissipate heat. In addition, the heat dissipation substrate itself can also provide a certain heat dissipation area, but due to processing accuracy and other issues, the part of the heat dissipation pipe that extends into the heat dissipation fin cannot completely contact with the heat dissipation fin, and there is inevitably a gap between the two. This reduces the efficiency of heat conduction from the heat pipe to the heat dissipation fins, thereby reducing the speed at which the heat is dissipated. It is still unable to effectively realize the heat dissipation of the LED high bay lamp, and for the heat dissipation fins, the processing is complicated. , the production efficiency is not high
