Summary: 
We have proposed an intelligent lighting system that provides required illuminance to required locations. The system can satisfy required illuminance in a few minutes by using the influence of the lightings and the illuminance sensors. However, there are cases where we want to brighten the location of low illuminance immediately. In this research, we propose an intelligent lighting system using visible light communication technology for direct communication between lightings and illuminance sensors. We confirmed that the illuminance converged to the preset target illuminance in a very short time and the system can respond adaptively to the movement of illuminance sensors.
