The reflector of the proposed light shelf system is modularized so that the length can be adjusted in stages. Therefore, in this study, we propose a light shelf with a width-adjustable reflector and verify its validity using a testbed.


However, the existing light shelves cannot actively deal with external environmental factors, which often lead to an infringement of the right to light during the night when the performance of the light shelf deteriorates. Most studies have focused on light shelves, which are daylighting systems used for reducing the lighting energy required for the interiors of buildings. In recent years, there has been an increase in the consumption of energy for lighting purposes, which has led to an increase in the number of studies being conducted on this subject.
