LIGHTING SHEET, LIGHTING DEVICE, AND BUILDING
PROBLEM TO BE SOLVED: To provide a lighting sheet capable of achieving efficient lighting while suppressing direct radiation of sunlight, and making an outdoor side visible.SOLUTION: The lighting sheet includes a base layer and a light-deflecting layer. The light-deflecting layer includes: light-transmitting parts arranged in a plurality of numbers along a surface of the base layer; and a light-deflecting part disposed among the plurality of light-transmitting parts and filled with an ultraviolet-curable resin composition having a refractive index lower than that of the light-transmitting parts. Top and back surfaces of the light-deflecting layer in a portion where the light-transmitting parts are disposed are formed parallel to each other. In a cross section along a thickness direction of the light-deflecting part, an upper side line is formed into a polygonal line having a plurality of straight connected lines or into a curved line, and the upper side line is formed to protrude downward; and a lower side line is formed into a straight line at an angle of 0° or more and 30° or less with respect to the normal line of the sheet surface. In the upper side line, an angle formed by an end portion on a side where light exits, with respect to the normal line of the sheet surface is smaller than an angle formed by the lower side line with respect to the normal line of the sheet surface; and a recess is formed on a side line corresponding to an opening side between the light-transmitting parts, of side lines formed between the upper side line and the lower side line.SELECTED DRAWING: Figure 3
【課題】太陽光の直射を抑制し、効率良く採光でき、室外側を目視可能な採光シートを提供する。【解決手段】基材層と、光偏向層と、を備え、光偏向層は、基材層の面に沿って複数配置された光透過部と、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、光偏向部は厚さ方向断面において、上部側の辺が、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になるように形成され、下部側の辺は直線状であるとともに、シート面法線に対して０°以上３０°以下であり、上部側の辺のうち光の出射側端部におけるシート面法線に対して成す角は、下部側シート面法線に対して成す角よりも小さく、上部側の辺と下部側の辺との間に形成される辺のうち、光透過部間の開口となる側の辺には凹部が設けられている。【選択図】図３
