<p>PROBLEM TO BE SOLVED: To efficiently light up the inside of a house with external light.SOLUTION: A daylighting system 1 includes: a first light control member 3 deflecting external light toward a ceiling surface in a house; and a second light control member 4 arranged along the ceiling surface and receiving the incident light deflected by the first light control member. The second light control member 4 includes: a light control layer 31 having a first main surface provided on a surface side on which the light deflected by the first light control member is made incident and a second main surface provided on the opposite side from the first main surface and partially inclined to the ceiling surface; and a reflection layer 32 laminated on the second main surface of the light control layer. The light control layer 31 refracts the light, deflected by the first light control member, by the first main surface and makes the light incident on the second main surface, and also refracts at least part of the light reflected by the reflection layer by the first main surface and then emits the light from the second light control member.</p> |
