description The emergency lighting device for the tunnel comprises a lighting lamp body, a fixing frame, four clamping plates and a locking driving structure, the locking driving structure is fixedly connected with the fixing frame, the four clamping plates are evenly distributed in the fixing frame, four connecting plates are arranged in the locking driving structure, and the locking driving structure is fixedly connected with the fixing frame. And the other end of the connecting plate sequentially penetrates through the locking driving structure and the fixing frame and is fixedly connected with the clamping plates, clamping structures are arranged on the inner sides of the four clamping plates, and the illuminating lamp body is arranged in the fixing frame through the clamping structures. By arranging the locking driving structure, the disassembly steps are effectively simplified, the illumination lamp body is disassembled through one-step operation, later maintenance of the illumination lamp body is facilitated, the
