NATURAL LIGHTING FILM, NATURAL LIGHTING FILM LAMINATE, NATURAL LIGHTING MEMBER AND NATURAL LIGHTING TOOL
PROBLEM TO BE SOLVED: To provide a natural lighting film capable of guiding more incident light to an indoor ceiling, etc.SOLUTION: A natural lighting film 10 includes: a polymer resin film having a first face configured to receive incident light and a second face opposing the first face and configured to emit light; and a plurality of craze areas 13 each arranged between the first face and the second face of the polymer resin film and configured to deflect the light incident from the first face to emit the light to the second face. If an interval of the craze areas 13 is P and a depth of a craze area is H, an aspect ratio P/H is 0.42-0.75. If a width of a craze area 13 is W, an opening ratio (1-(W/P))×100 is 90% or more.SELECTED DRAWING: Figure 2
【課題】入射した光をより多く室内の天井等に導くことができる採光フィルムを提供する。【解決手段】採光フィルム１０は、光が入射する第１面及び前記第１面に対向し、光が出射する第２面を有する高分子樹脂フィルムと、前記高分子樹脂フィルムの前記第１面及び前記第２面の間に配置され、前記第１面から入射した光を偏向して前記第２面に出射するクレイズ領域１３を複数備え、クレイズ領域１３の間隔をＰ、前記クレイズ領域の深さをＨとした場合のアスペクト比Ｐ／Ｈが０．４２から０．７５であり、クレイズ領域１３の幅をＷとした場合の開口率（１−（Ｗ／Ｐ））×１００が９０％以上である。【選択図】図２
