Design of Lighting Control System Considering Lighting Uniformity and Discomfort Glare for Indoor Space

In the modern society, the indoor lighting environment has an uneven illuminance distribution due to artificial lighting having optical properties such as fixed illuminance, color temperature, and light influx from outside. Because fatigue of the eyes is accumulated in the uneven illumination environment and the brightness of background is changed according to the position of the occupant, discomfort glare occurs when light of high luminance against the brightness adapted to the eyes lights up the eyes. In order to construct a pleasant indoor lighting environment, it is necessary to develop an illumination system that can maintain lighting uniformity and reduce glare. In this paper, we propose a lighting control system considering discomfort glare while maintaining lighting uniformity of indoor space.
