[0002] Tri-proof lamps are special lighting equipment made of special protective materials, with dustproof, waterproof, explosion-proof (anti-corrosion) functions. Their light sources are usually LEDs, which are highly efficient and energy-saving. This type of lamp is widely used in various places with high requirements for environmental conditions, especially in areas that need to be moisture-proof, dust-proof, and anti-corrosion. For example, tri-proof lamps are often used in humid environments such as bathrooms and saunas to ensure that the lamps are not corroded by water vapor during long-term use. In public places such as hospitals, canteens, and shopping malls, tri-proof lamps provide safe and reliable lighting to prevent dust or moisture from entering the interior of the lamp and affecting its normal operation.

[0003] Therefore, the sealing tightness of the tri-proof lamp is very important. The Chinese utility model patent with announcement number CN209655113U discloses a tri-proof lamp.

[0017] The three-proof lamp provided by the utility model has the following advantages:

[0018] Compared with the prior art, the utility model forms a ring groove between the outer frame and the inner frame of the lamp housing, and arranges a waterproof ring in the ring groove. The waterproof ring includes an inner ring groove and an outer ring groove, which are respectively used for the plugging and fixing of the vertical flange and the ring plug plate, thereby significantly improving the airtightness of the lamp. In particular, in terms of waterproofing, the double ring groove structure effectively prevents water vapor, dust, etc. from entering the interior of the lamp, thereby improving the protective performance. At the same time, the flat flange of the lampshade and the vertical ring plug plate design make the buckle between the lampshade and the lamp housing more tightly, and the vertical flange of the radiator is mutually buckled through the card block and the card hole to ensure the stable connection between the lampshade and the lamp housing, thereby enhancing the structural stability of the lamp in long-term use. In addition, the vertical flange of the radiator not only increases the heat dissipation area, but also provides effective support in the overall structure. The optimized heat dissipation design helps to extend the service life of the lamp and improve its working stability in harsh environments. The overall design is particularly suitable for places with high requirements for airtightness and protection, such as bathrooms, workshops and warehouses, which are humid, dusty or corrosive environments, and effectively solves the shortcomings of the existing three-proof lamps in terms of sealing and protection.
