PROBLEM TO BE SOLVED: To provide a daylighting system for hardly causing a reduction in the utilization efficiency of light even in the state of inhibiting the light from being brought thereinto.SOLUTION: A daylighting system 10 includes a daylighting structure 20 having a daylighting opening 21 through which light is brought thereinto, and a solar battery panel 30. A light flux L1 moving from a first direction d1 to the daylighting opening 21 has a greater quantity of light to be brought into the daylighting structure 20 than a light flux L2 moving from a second direction d2 inclined toward the further upward side than the first direction d1 to the daylighting opening 21. At least part of the light which is not brought into the daylighting structure 20, out of the light flux L2 moving from the second direction d2 to the daylighting opening 21, enters into the solar battery panel 30.SELECTED DRAWING: Figure 1 |
