A ceiling illumination window (1) is provided with a transparent prism (30), and a reflecting member (40) provided on a second edge (30b) of the transparent prism (30). Further, the transparent prism(30) is installed in such a way as to enable light incident thereon at an angle, relative to a normal line to first and second transparent plates (10a, 10b), that is at least equal to a prescribed angle to be reflected at a third edge (30c) using a critical angle. In addition, when light is incident at an angle at least equal to the prescribed angle relative to the normal line, the transparent prism (30) emits the light toward an indoor ceiling side using at least two types of optical path having different numbers of reflections, using reflection at at least one of the transparent prism (30) surface and the reflecting member (40), and when light is incident at an angle less than the prescribed angle, the transparent prism allows the light to be transmitted through the third edge (30c).
一种天花板照明窗(1)设置有透明棱镜(30)以及设置在该透明棱镜(30)的第二边缘(30b)上的反射构件(40)。此外，透明棱镜(30)安装成使得以相对于第一和第二透明板(10a、10b)的法线至少等于规定角度的角度入射在其上的光能够在第三边缘(30c)处使用临界角反射。另外，当光以相对于法线至少等于规定角度的角度入射时，透明棱镜(30)使用具有不同反射次数的至少两种光路、使用透明棱镜(30)表面和反射构件(40)中至少一个的反射向室内天花板侧发射光，并且当光以小于规定角度的角度入射时，透明棱镜允许光透射通过第三边缘(30c)。
