Distributed control of illumination using flat prism and achieving accuracy of individual illuminance in office

我々はオフィスにおける執務の快適性向上を目的とした知的照明システムの研究を行っている．知的照明システムは，各照明を適切な明るさで点灯させることにより執務者が要求する照度を個別に実現する．しかし，使用する照明の配光特性と設置間隔およびオフィスレイアウトの関係により，執務者が要求する照度を個別に実現できないことがある．本研究では照明の配光特性に着目し，平面プリズムという光を屈折させる器材を用いて照明の配光方向を変化させる．照明の配光方向を知的照明システムの制御対象として加え，オフィスレイアウトに適した配光方向を決定することで，各執務者が要求する照度を高精度で実現可能な新たな知的照明システムの構築を目指す．We are conducting research on Intelligent Lighting System aiming at improvement of comfort in office work. The Intelligent Lighting System individually realizes illuminance required by office workers by adjusting the light with appropriate brightness. The realization of illuminance accurately is related to the installation interval of lighting, the light distribution characteristics, and office layout. From these relationships, it can not be realized the illuminance desired by the office worker. In our research, we focused on the characteristics of light distribution and changed the direction of light distribution by using a flat prism that refracts light. And determine the light distribution direction suitable for the office layout. We aim to build an ILS that can realize the illuminance desired by the office worker with high accuracy
