We propose a distributed lighting control system composed of multiple LED lights and switchable shades, the transparency of which can be changed independently. Distributed controllers are embedded in all the lights and shades, and they communicate to determine the appropriate lighting and shading patterns required to realize a desired illuminance distribution. In this paper, we first formulated the design problem of setting the distributed controllers, such that the actual illuminance distribution is similar to the desired one. Then, we proposed a distributed algorithm that determines the lighting and shading patterns of the LED lights and shades. Finally, we verified the effectiveness of the proposed algorithm through the results of simulations and real-world experiments using a developed system.
