LIGHTING FILM
PROBLEM TO BE SOLVED: To improve lighting efficiency.SOLUTION: A lighting film 1 changes propagation directions of incident light to exit and includes a plurality of louvers 11 formed as spaced along one surface of the film and a base part 12 disposed around the plurality of louvers. When the lighting film is disposed with the film surfaces along a vertical direction, each of the plurality of louvers has a first face 11a for specular reflection which is disposed at a top side and extends in a direction intersecting the one surface of the film, and a second face 11b which is disposed at a bottom side and extends in a direction intersecting the one surface. The second face has at least one of a refractive index interface with the base part and a specular reflection surface. The second face is disposed as inclined to be closer to the top side along a direction from the one surface side toward the other surface of the film.SELECTED DRAWING: Figure 1
【課題】採光効率を向上させる。【解決手段】採光フィルム1は、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において、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11と、複数のルーバー部の周囲に設けられるベース部12と、を備え、複数のルーバー部のそれぞれは、当該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、天側に配置され一方の面に交差する方向に伸びる鏡面反射を行う第1面11aと、地面側に配置され一方の面に交差する方向に伸びる第2面11bと、を有し、第2面は、ベース部との屈折率界面および鏡面反射面の少なくとも一方を有し、第2面は、一方の面側から対向する他方の面側に向かうにつれて天側に近づくように傾斜して配置される。【選択図】図1
