[0032] The existing lighting system in the tunnel usually fixes the lamp body 3 to the mounting plate 1 on the side wall of the tunnel by means of bolts. As a result, the position of the lamp body 3 cannot be adjusted after installation. Once the position of the lamp body 3 deviates, the lamp body 3 needs to be removed from the mounting plate 1 and reinstalled, which is quite troublesome. Therefore, the present technical solution is provided with a movable block 2 on the existing mounting plate 1, wherein the mounting plate 1 is fixed to the side wall of the tunnel by means of bolts, and a certain space is left between the mounting plate 1 and the top of the tunnel. The movable block 2 arranged in the mounting plate 1 can be moved on the mounting plate 1 along the direction of vehicle travel, and the position of the movable block 2 in the mounting plate 1 can be changed. The position of the plate 1 is adjusted, thereby realizing the adjustment of the horizontal position of the lamp body 3 located below the movable block 2. At the same time, a height adjustment member is also provided on the movable block 2, and the height adjustment member is used to adjust the vertical position of the lamp body 3 in the tunnel; a connecting ball 11 for adjusting the inclination angle of the lamp body 3 is also provided at the bottom of the height adjustment member, and a mounting groove 28 and a rotating shaft 15 are provided on the connecting ball 11.
