DAYLIGHTING SHEET, DAYLIGHTING DEVICE AND BUILDING
PROBLEM TO BE SOLVED: To provide a daylighting sheet capable of suppressing direct projection of sunlight (direct incident light), allowing efficient lighting, and making an outdoor side visible from an indoor side.SOLUTION: A daylighting sheet includes: a base material layer; and a light deflection layer configured to deflect light. The light deflection layer includes: a plurality of light transmission parts aligned along one side of the base material layer and configured to transmit light; and light deflection parts arranged between the plurality of light transmission parts and filled with an ultra-violet ray curable resin composition having a refractive index lower than the light transmission part. At a portion with the light transmission part arranged, the front and back sides of the light deflection layer are formed in parallel. Under a state where the daylighting sheet is arranged at an opening of a building, in a vertical section in a thickness direction of the daylighting sheet, the upper side of the light deflection part is formed as a polygonal line in which a plurality of straight lines continue, or a curved line, and the upper side is formed projecting downward at an angle of 0-23.1°, inclusive, relative to the normal line of the sheet surface.SELECTED DRAWING: Figure 3
【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】基材層と、光を偏向する光偏向層と、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紫外線硬化型樹脂の組成物が充填された光偏向部と、を有し、光透過部が配置された部位の光偏向層の表裏面は平行に形成されており、採光シートが建物開口部に配置された姿勢で、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、シート面法線に対して０°以上２３．１°以下で下に凸となるよう形成される。【選択図】図３
