LIGHTING SHEET, LIGHTING DEVICE, AND BUILDING
PROBLEM TO BE SOLVED: To provide a lighting sheet that can suppress direct radiation (direct incident light) of sunlight, achieves efficient lighting, and makes an outdoor side visible from an indoor side.SOLUTION: A lighting sheet 20 is disposed on an opening of a building, with a sheet surface set vertical; and the sheet includes a light-transmitting substrate layer 22 and a light-deflecting layer 23 that is formed on one surface of the substrate layer and deflects light. The light-deflecting layer includes: a plurality of light-transmitting portions 24 arranged along the one surface of the substrate layer and transmitting light; and light-deflecting portions 25 disposed among the plurality of the light-transmitting portions and filled with a material having a refractive index lower than that of the light-transmitting portions. In a posture of the lighting sheet disposed on an opening of a building, the light-deflecting portion is configured in such a manner that, on a cross section along a thickness direction of the lighting sheet, an upper side edge of the light-deflection portion is composed of a polygonal line including a plurality of connected straight lines and is formed to be convex downward. The downwardly convex figure of the upper edge is formed in such a manner that an inclination angle of a portion at an outdoor side with respect to a horizontal plane is larger than an inclination angle of a portion at an indoor side with respect to the horizontal plane.
【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、上部となる側の辺における下に凸は、上部となる側の辺のうち室外側における水平面に対する傾斜角が、室内側における水平面に対する傾斜角よりも大きく形成されている。【選択図】図３
