DAYLIGHTING SHEET, DAYLIGHTING DEVICE, AND BUILDING
PROBLEM TO BE SOLVED: To provide a daylighting sheet which suppresses direct sunlight (direct incident light), provides effective daylighting, and allows for viewing outside therethrough from inside.SOLUTION: A daylighting sheet 20 is to be placed over openings of a building such that a sheet surface is vertically oriented, and includes a translucent base material layer 22 and a light deflection layer 23 which is formed on one surface of the base material layer to deflect light, the light deflection layer comprising a plurality of light transmissive sections 24, which are arranged next to each other along the one surface of the base material layer to transmit light, and light deflection sections 25 which are arranged between the plurality of light transmissive sections and are filled with a material having a refractive index lower than that of the light transmissive sections. With the daylighting sheet positioned on an opening of the building, each of the light deflection sections, in a cross-section in a thickness direction of the daylighting sheet, has an upper side having a shape that is either a polygonal line comprising a continuous plurality of lines or a curve and is convex downward, whereas a lower side opposite the upper side is one straight line that is tilted by 0-30°, inclusive, relative to the normal line of the daylighting sheet.
【課題】太陽光の直射（直達光）を抑制するとともに効率良く採光でき、室内側から室外側を見ることが可能な採光シートを提供する。【解決手段】シート面が鉛直となるように建物開口部に配置される採光シート２０であって、透光性を有する基材層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、上部となる側の辺の反対側の下部となる側の辺は、１つの直線状であるとともに、採光シートのシート面法線に対して０?以上３０?以下である。【選択図】図３
