Description

Lighting devices for tunnel construction

Technical Field

The utility model relates to the technical field of tunnel construction lighting, in particular to a lighting device for tunnel construction.

Background technique

During tunnel construction, mobile temporary lighting is generally used. The biggest advantage of this type of lighting is that it is portable and can be moved at any time. However, because it is placed very close to the construction site, a lot of dust will be collected on the lampshade shortly after the lighting is used. If it is not handled in time, the dust will solidify on the lampshade due to humid air, and it will be difficult to clean over time. If it is wiped manually, it is easy to get an electric shock. Secondly, it will leave marks on the lampshade due to improper wiping or inadequate wiping. In order to quickly and cost-effectively clean the dust, we proposed a lighting device for tunnel construction.
