[0004] The above-mentioned LED explosion-proof work light has the following disadvantages: 1. When the explosion-proof work light leaves the factory, the main body of the explosion-proof work light needs to be sprayed with paint. However, the lamp holder is bowl-shaped with a smooth outer surface. It is easy to bump when placed after spraying the paint. Once bumped, the surface is obviously concave, which affects the appearance of the product. At the same time, the shape of the lamp holder causes its strength to be low; 2. The water passage arranged in the wiring cavity is prone to water accumulation. The accumulated water in the explosion-proof work lamp for a long time will cause damage or corrosion to the components inside it, resulting in electric shock to the operator or the explosion-proof work lamp cannot be used normally, thereby increasing the maintenance cost; 3. In combination with Figure 9 of the specification of the patent document with patent application number CN202410408598.1, the connecting ear for installing the locking bolt arranged on the outer periphery of the explosion-proof cavity is close to the water passage, which causes water to easily accumulate between the connecting ear and the water passage, thereby damaging the internal components of the explosion-proof work lamp.
