OPTICAL ELEMENT AND MANUFACTURING METHOD THEREOF, AND LUMINAIRE, WINDOW MATERIAL AND FIXTURE
PROBLEM TO BE SOLVED: To provide an optical element capable of efficiently emitting light incident in a predetermined angular range in a predetermined angular range, and to provide a manufacturing method of the same, a luminaire, window material and a fixture.SOLUTION: An optical element includes: a first surface S1; a second surface S2 facing the first surface; and a plurality of reflection surfaces 151r aligned inside a first region defined by the first surface and the second surface. The plurality of reflection surfaces have a first length d in a first direction perpendicular to the first surface, and are arrayed along a second direction orthogonal to the first direction. Light entering one surface of the first surface and the second surface is reflected toward the other surface by the plurality of reflection surfaces. The optical element satisfies a conditional expression related to first length, the number of total reflection, an array pitch p of the reflection surfaces, an angle formed between a projection to a plane including the first and second directions of light entering the reflection surface and a tangential line at any point on the reflection surface, a refractive index inside the region defined by the first surface and the second surface, and the like.
【課題】所定の角度範囲で入射する光を所定の角度範囲に効率よく出射することができる光学素子およびその製造方法ならびに照明装置、窓材および建具を提供する。【解決手段】第１の面Ｓ１と、前記第１の面に対向する第２の面Ｓ２と、前記第１の面および前記第２の面で規定される第１の領域の内部に配列される複数の反射面１５１ｒとを備え、前記複数の反射面が、前記第１の面に垂直な第１の方向に第１の長さｄを有し、前記第１の方向と直交する第２の方向に沿って配列され、前記第１の面または前記第２の面のうち、一方の面に入射した光が、前記複数の反射面により他方の面に向けて反射され、光学素子は、第１の長さ、全反射する回数、反射面の配列ピッチｐ、反射面に入射する光の第１および第２の方向を含む面への射影と反射面の任意の点における接線とのなす角、第１の面および第２の面で規定される領域の内部の屈折率、等に関する条件式を満たす。【選択図】図２
