Faster illuminance convergence for the intelligent lighting system using visible light communication

Abstract

We have been proposing the Intelligent Lighting System that can provide specific sections of the office space with lightings of varying illuminance. Using the influence of lightings on illuminance sensors, the system can satisfy the required lighting conditions within a few minutes. However, in some cases a spot must be lit up more quickly. In this research, we propose an improvement to the Intelligent Lighting System that uses visible light communication to achieve direct communication between the lights and illuminance sensors. We confirmed that the new system is able to make illuminance converge to a preset target in considerably shorter times and that it can respond adaptively to the movements of illuminance sensors.
