Through the coordinated use of the protective cover 7, the circular ring 8 and the transparent cover 9, the surface of the explosion-proof lamp housing 1 and the front side of the bulb 3 are shielded and protected respectively, thereby preventing the broken stones or man-made tools in the tunnel from causing damage to the bulb. A condenser 2 is fixedly installed in the inner cavity of the explosion-proof lamp housing 1, a bulb 3 is installed in the inner cavity of the explosion-proof lamp housing 1, and the condenser 2 is arranged on the surface of the bulb 3. A rotating frame 4 is arranged on the rear side of the explosion-proof lamp housing 1, and connecting blocks 11 are welded to the rear ends of both sides of the explosion-proof lamp housing 1, and bolts 12 are penetrated on one side of the connecting block 11. The rotating frame 4 and the connecting block 11 are fixedly connected by the bolts 12. The rear side of the frame 4 is provided with a fastening assembly 6, which includes a rectangular groove 61 opened on the rear side of the rotating frame 4, and a hanging ring 62 is welded on the front side of the inner cavity of the rectangular groove 61.
