<p>PROBLEM TO BE SOLVED: To perform blocking of light by absorbing heat rays included in sunlight and intake of sunlight into indoors to use the light for illumination, in a well balanced condition.SOLUTION: A light-controlling sheet 100 is mounted on a light-incident part 200 to capture sunlight. The light-controlling sheet 100 includes: a heat ray absorbing group 11a comprising a plurality of heat ray absorbing parts 11 which are disposed within a sheet plane along a predetermined direction and absorb heat rays included in sunlight; a light-reflecting group 12a comprising a plurality of light-reflecting parts 12 which are disposed within the sheet plane along a predetermined direction and reflect sunlight toward an indoor ceiling so as to introduce the light into an opposite side to the incident side of the light; and a light-transmitting part 16 which is disposed within the sheet plane in a part where neither the heat ray absorbing part 11 nor the light-reflecting part 12 is disposed, and which transmits sunlight. When the sheet is mounted on the light-incident part 200, the light-reflecting group 12a is located above the heat ray absorbing group 11a.</p> |
