It must be done and electrical work cannot respond promptly to the progress of the work site. Further, since the installation position of the temporary distribution board is separated from the work site as the work site progresses, an overload current flows through the F cable due to the use of the electric tool, and the temporary distribution board is installed on the temporary distribution board. When the breaker is turned off and the power supply is cut off, it is necessary for an operator to go to the temporary distribution board in the dark without lighting and operate the breaker to the on state. Since the temporary distribution board is installed away from the work site, the labor of the worker who moves when the breaker is activated increases the work efficiency, and the safety management becomes more dangerous. .

Further, a stand having a conventional structure equipped with an incandescent lamp or a fluorescent lamp can cope with the movement of the working space, but since the required illuminance is constant, a desired illuminance according to the type of job and the process can be obtained. However, if an overload current flows through the F-cable and the breaker installed on the temporary distribution board operates, each time a worker temporarily installs it, as in the case of an incandescent lamp or a fluorescent lamp. There is a drawback that the work efficiency becomes poor because it is necessary to go to the distribution board.

The present invention has been made in view of the above points, and it is possible to easily obtain a desired illuminance according to a job type and a process, and it is not necessary for an operator to go to a temporary distribution board. The purpose of the present invention is to provide a lighting stand for construction work, which is designed to improve work efficiency and safety management.
