[0002] LED, the full name of which is light emitting diode, is a commonly used light emitting device. It emits light by releasing energy through the recombination of electrons and holes. It can efficiently convert electrical energy into light energy. It has a wide range of uses in modern society, such as lighting, flat panel displays, medical devices, etc. It has the characteristics of high light efficiency, good color rendering, no flicker, instant start, and no fear of vibration. In particular, it has the advantages of long life and is a maintenance-free green energy-saving light source. When LED is used for lighting, it is usually used with a reflector cover, which can reflect and focus the light emitted by the LED and gather the light into a beam for lighting needs. However, the existing ones still have certain defects when used;

[0003] For example, the heat dissipation and anti-glare structure of an LED lamp with a reflector cover with announcement number CN214619396U adopts a bowl-shaped reflector with a large surface area and a high depth, and sets longitudinally arranged main heat dissipation fins and auxiliary heat dissipation fins on both sides of the top of the bowl-shaped reflector, which effectively improves the heat dissipation efficiency of the high-power LED lamp, thereby greatly improving the luminous efficiency and service life of the LED lamp; at the same time, the bowl-shaped reflector increases the shading angle, solving the problem of glare damaging the on-site staff and affecting the work efficiency;

[0004] Since high-power LED lamps are often used outdoors and are often exposed to wind and rain, and the above-mentioned LED lamp reflector device is not provided with a rainproof structure, rainwater can easily penetrate into the interior of the lamp through the gaps and cause damage to the internal parts, which in turn causes the lamp to need frequent maintenance and replacement of parts, or causes the lamp to be scrapped and needs to be replaced entirely, and the device is not very practical;

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original equipment. Therefore, we propose an LED reflector with a waterproof heat dissipation structure that can well solve the above problems. Utility Model Content
