Description

Technical Field

[0001] The utility model relates to the technical field of tunnel lighting fixtures, in particular to a tunnel lighting fixture which is easy to install and disassemble. Background Art

[0002] Tunnel lighting can improve the road conditions in the tunnel, improve the visual enjoyment in the tunnel, reduce driver fatigue, and help improve the tunnel's traffic capacity to ensure traffic safety. The continuous expansion of my country's infrastructure has resulted in a large number of tunnel sections. When the lighting lamps in the tunnel are inspected or damaged, the staff need to use a professional maintenance vehicle to lift them to high altitudes for inspection. The lighting lamps are usually protected by lampshades, and the lampshades usually need to be fixed by threads. Therefore, when disassembling, the bolts must also be removed before the lamps can be removed, which makes the disassembly process more troublesome. During installation, in order to ensure the continuity and uniformity of subsequent lighting, the lighting lamp body needs to be installed in a straight line. However, manual measurement and positioning are currently required before installation to ensure that the entire lamp is in the same straight line, which is more troublesome. Therefore, we have introduced a new tunnel lighting fixture that is easy to install and disassemble. Utility Model Content
