Description

請求項１に記載の発明は、シート面が鉛直となるように建物開口部に配置されるシート状である採光シート（２０、１２０）であって、透光性を有するシート状の基材層（２２）と、基材層の一方の面に形成され、光を偏向する光偏向層（２３、１２３）と、を備え、光偏向層は、基材層の一方の面に沿って複数並べて配置された光を透過する光透過部（２４）と、複数の光透過部間に配置され、該光透過部よりも低い屈折率の材料が充填された光偏向部（２５、１２５）と、を有し、採光シートが建物開口部に配置された姿勢で、光偏向部は採光シートの厚さ方向断面において、その上部となる側の辺が、複数の直線が連続した折れ線、又は曲線状で形成されており、上部となる側の辺は、下に凸となるよう形成されており、採光シートが建物開口部に配置された姿勢で、隣り合う光偏向部の間隔は、室外側より室内側が広くなる形状である採光シートである。 The invention according to claim 1 is a daylighting sheet (20, 120) in the form of a sheet disposed in a building opening so that the sheet surface is vertical, and is a sheet-like base material layer having translucency. (22) and a light deflection layer (23, 123) that is formed on one surface of the base material layer and deflects light, and a plurality of light deflection layers are arranged along one surface of the base material layer. A light transmission part (24) that transmits the disposed light, a light deflection part (25, 125) that is disposed between the plurality of light transmission parts and is filled with a material having a lower refractive index than the light transmission part, And the light deflector is in a cross section in the thickness direction of the daylighting sheet, and the upper side of the daylighting sheet is a broken line or a curved line in which a plurality of straight lines are continuous. in which is formed, and made of the sides the top, is formed so as to be convex downward, the lighting sheet In a posture which is arranged at the object opening, the distance of the light deflection unit adjacent a daylighting sheet is shaped from the outdoor side compartment side becomes wider.

Claims

It is a daylighting sheet that is in the form of a sheet placed in the building opening so that the sheet surface is vertical,
A sheet-like base material layer having translucency;
A light deflection layer formed on one surface of the base material layer for deflecting light,
