Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a tunnel following lighting device. Background Art

[0002] Existing tunnel lighting systems use a fixed-angle approach, meaning the lighting fixtures are installed at a fixed angle and don't adjust according to actual conditions. However, in practice, changing tunnel traffic conditions can lead to changing lighting requirements. For example, a larger illumination range for a particular fixture may be desired, necessitating adjustments to the fixture's angle. Alternatively, technological upgrades to tunnel lighting systems may require fixtures that can oscillate with vehicles to provide more precise illumination. Existing lighting systems cannot meet these requirements. Utility Model Content

[0024] First rotating motor 6 drives the rotation of first rotating shaft 5, and first rotating shaft 5 drives the rotation of first branch 4 relative to second branch 7, so that main lighting component 1 swings relative to the extension direction of first branch 4, which can also be understood as that main lighting component 1 rotates on its own axis. When main lighting component 1 is completely directed downward, its main lighting range is concentrated directly below it, and the lighting range is smallest. When main lighting component 1 swings, its lighting range is appropriately enlarged, and the lighting position is more forward or backward. Assuming that the driving direction is forward, main lighting component 1 swings backward, and its lighting range is actually closer to the oncoming vehicle, that is, the vehicle can enter the lighting range of main lighting component 1 more quickly. The change in the swing angle of main lighting component 1 caused by the rotation of first branch 4 is relatively small. If a larger angle needs to be adjusted, second rotating motor 10 and the rotation of second branch 7 are needed. Second rotating motor 10 drives the rotation of second rotating shaft 9, and second rotating shaft 9 drives the rotation of second branch 7 relative to third branch 8. When second branch 7 swings backward, first branch 4 and main lighting component 1 swing backward together with second branch 7, and the lighting range of main lighting component 1 is closer to the oncoming vehicle, that is, the vehicle can enter the lighting range of main lighting component 1 more quickly.
