DAYLIGHTING FILM, DAYLIGHTING TOOL, AND DAYLIGHTING FILM MANUFACTURING METHOD
PROBLEM TO BE SOLVED: To provide a daylighting film that offers enhanced anti-reflection performance without reducing daylighting efficiency.SOLUTION: A daylighting film 1 comprises a plurality of light control layers laminated together, each comprising a base portion 3 having a plurality of grooves formed to be spaced apart from each other along one surface thereof and a plurality of louver portions 4 which has a refractive index different from that of the base portion and fill the plurality of grooves. Positions of the plurality of louver portions of at least one of the plurality of light control layers are shifted, in a direction in which the plurality of louver portions are arrayed on the one surface, relative to those of the plurality of louver portions of at least another light control layer.
【課題】採光効率を低下させずに防眩性能を向上させる。【解決手段】採光フィルム１は、積層された複数の光制御層を備え、複数の光制御層のそれぞれは、一方の面に沿って離隔して形成される複数の溝を有するベース部３と、ベース部とは異なる屈折率を持ち複数の溝内に充填した複数のルーバー部４と、を有し、複数の光制御層のうち少なくとも一つの光制御層における複数のルーバー部と、その他の少なくとも一つの光制御層における複数のルーバー部とは、一方の面上の複数のルーバー部の並ぶ方向における各ルーバー部の位置がそれぞれずれている。【選択図】図１
