[0002] With the progress and development of society, the demand for lamps in industrial production is becoming more and more urgent, especially for mining lamps. As a new type of mining lighting equipment, waterproof and explosion-proof LED bracket lamps have many advantages such as high brightness, low energy consumption, long life and small size. They can greatly meet the lighting needs of mine work and provide mine workers with a more comfortable and efficient lighting environment. The existing waterproof and explosion-proof LED bracket lamps are generally composed of a lamp housing, a tempered glass lens plate, an LED wick, etc. The tempered glass lens plate and the lamp housing are sealed and connected by a rubber pad, which has a good waterproof and explosion-proof effect. However, the lamps generally only have a single-layer tempered glass lens plate, which generally does not have a force unloading function after being impacted. When it is damaged, the internal sealing environment will be destroyed, and there will be certain safety hazards. At the same time, the irradiation area cannot be adjusted when the installation position of the lamp remains unchanged, so the use effect is general. Utility Model Content
