Description

Technical Field

[0001] The utility model relates to a lighting device, in particular to a lighting device used for a tunnel exit. Background Art

[0002] Tunnels are passages specially used for automobile transportation. With the development of social economy and production, a large number of expressways have emerged, which have put forward higher standards for road construction technology, requiring straight lines, gentle slopes, and wide roads. Therefore, when roads pass through mountainous areas, the previous winding routes are mostly changed to tunnel routes. The construction of tunnels plays an important role in improving the technical status of roads, shortening operating distances, increasing transportation capacity, and reducing accidents. In order to facilitate the driving of cars in tunnels, lighting fixtures need to be installed on the inner walls of tunnels. Therefore, lighting devices used in tunnels are an important tunnel supply. Among the existing lighting devices used in tunnels, there is no lighting device for tunnel exits. Lighting fixtures are still installed on the inner walls of tunnels. When the driver exits the tunnel exit, due to the difference in light intensity between the outside of the tunnel exit and the inside of the tunnel, it will affect the driver's vision, thereby affecting the safety performance of exiting the tunnel exit.

[0003] The utility model has the technical feature of adaptively eliminating the difference in light intensity between the outside of the tunnel exit and the tunnel, and has effectively explored and studied the technical problem of fixing lighting fixtures on the inner wall of the tunnel.
