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 from an indoor side.SOLUTION: The lighting sheet includes a base layer 22 and a light-deflecting layer 23. The light-deflecting layer includes: light-transmitting parts 24 arranged in a plurality of numbers along a surface of the base layer; and a light-deflecting part 25 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 of the light-deflecting part along a thickness direction of the lighting sheet 20, 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 at an angle of 0° or more and 23.1° or less with respect to the normal line of the sheet surface; and a lower side line opposite to the upper side line is formed into a straight line. 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２２と、光偏向層２３と、を備え、光偏向層は、基材層の面に沿って複数並べて配置された光透過部２４と、複数の光透過部間に配置され、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２５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、光偏向部は採光シート２０の厚さ方向断面において、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°以下で下に凸になるように形成され、上部となる側の辺とは反対側の下部となる側の辺は直線状であり上部となる側の辺と下部となる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
