LIGHTING FILM
PROBLEM TO BE SOLVED: To improve lighting efficiency with a simple structure.SOLUTION: A lighting film 1 changes propagation directions of light incident from one surface side of the film to exit, and includes a plurality of louvers 13 formed as spaced along the one surface of the film, and a base part 12 disposed around the plurality of louvers. Each of the plurality of louvers has a plurality of reflection faces 14a, 14b having different inclination angles with respect to the normal direction of the one surface. When the lighting film is disposed with the film surfaces along a vertical direction, an angle of the reflection face closest to the one surface of the film in the plurality of reflection surfaces, with respect to the normal direction of the one surface of the film, is larger than those of other reflection faces, where an angle from the normal direction of the one surface directing the exit side to a downward direction is set to be a positive angle.SELECTED DRAWING: Figure 1
【課題】簡易な構造で採光効率を向上させることができる。【解決手段】一方の面側から入射された光の進行方向を変化させて出射させる採光フィルム1は、一方の面に沿って離隔して形成される複数のルーバー部13と、複数のルーバー部の周囲に設けられるベース部3と、を備え、複数のルーバー部のそれぞれは、一方の面の法線方向に対する傾斜角度がそれぞれ異なる複数の反射面14a,14bを有し、前記採光フィルムのフィルム面を天地方向に配置したときに、前記一方の面の出射側を向いた法線方向から地面側の方向への為す角度を正として、複数の反射面のうち、一方の面に最も近い位置に配置された反射面は、残りの反射面よりも一方の面の法線方向に対する角度が大きい。【選択図】図1
