By the way, in the night work at the railway site, a thorough thing confirmation work must be performed after the night work in order to avoid the transportation trouble caused by the left thing after the night work.
However, since it is common to check forgotten things after the night work in the past, it has been possible to lead to transportation troubles as a result of leaving behind forgotten things due to human error. In addition, since there is no means for confirming forgotten things after the fact and it is necessary to rely on the memory of the workers, it is difficult to specify the time when the forgotten things were placed.

  On the other hand, for example, a method in which a camera is mounted on a helmet and the state after the night work is completed and recorded as a record can be considered. However, since a lighting device is already attached to a helmet for night work, if a camera is attached to the helmet separately, the weight and volume of the deposit on the helmet will increase, leading to a decrease in the workability of workers. There is a risk that.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a camera-equipped lighting device that can illuminate and image a night scene without impairing the workability of night work.
