However, the above-mentioned conventional outdoor lighting automatic control system controls only the lighting provided on the outdoor side of the entrance (hereinafter referred to as "outdoor lighting"). Therefore, the lighting such as the entrance hall light normally provided on the indoor side of the entrance is not controlled. Therefore, for example, when responding to a night visitor, it was necessary to once go to the entrance and manually operate a wall switch in the entrance hall to turn on the entrance hall light. Also, in the case of returning home at night, when no one is present, it was necessary to open the doorway, find the wall switch of the entrance hall light in the dark, and manually turn it on. Furthermore, when going out at night, it was necessary to turn on the entrance hall light manually, put on shoes, and then manually turn off the entrance hall light again and shut the door.

As described above, in an automatic lighting control system for controlling only outdoor lighting, it is troublesome to manually turn off indoor lighting (hereinafter, referred to as "indoor lighting") such as an entrance hall light. For example, when it is not possible to respond to customers immediately, or when going in and out with luggage in both hands, it is extremely inconvenient. Of course, it is possible to keep the indoor lighting on all the time, but that would waste energy.
Switches that turn off the entrance hall lights and the like after a certain period of time have already become widespread, but this alone does not enable effective control particularly for lighting.

The present invention has been made to eliminate such inconvenience. That is, the problem to be solved by the present invention is to automatically control both the outdoor lighting and the indoor lighting provided across the doorway while interlocking with each other according to the entering and exiting of the person, thereby further turning off the light according to the entering and exiting of the person. An object of the present invention is to provide a doorway lighting control system that can save labor.
