To provide a ceiling illumination window which can illuminate a room from a window side to an inner side in hot season and which can illuminate a ceiling more brightly while making it easy to see a clear view.SOLUTION: A ceiling illumination window 1 includes a transparent prism 30, and a reflecting member 40 provided on a second side 30b of the transparent prism 30. The transparent prism 30 is installed so as to enable the reflection using a critical angle in a third side 30c with respect to light incident at a predetermined angle or more with respect to normal lines of first and second transparent plates 10a and 10b. In addition, when light is incident at the predetermined angle or more with respect to the normal line, the transparent prism 30 emits light toward the interior ceiling side through two or more kinds of light paths having different numbers of reflections using the reflection from at least one of the surface of the transparent prism 30 and the reflecting member 40, and when light is incident at an angle less than the predetermined angle, the light is caused to pass through the third side 30c.SELECTED DRAWING: Figure 1
【課題】夏場において室内を窓側から奥側にかけて照明することができると共に、天井をより明るく照らすことと景色の見え易さの両立を図ることができる天井照射窓を提供する。【解決手段】天井照射窓１は、透明性プリズム３０と、透明性プリズム３０の第２の辺３０ｂに設けられる反射部材４０とを備えている。また、透明性プリズム３０は、第１及び第２透明性板材１０ａ，１０ｂの法線に対する角度が所定角度以上で入射する光について、第３の辺３０ｃにおける臨界角を利用した反射が可能に設置されている。加えて、透明性プリズム３０は、法線に対する角度が所定角度以上の光が入射した場合、透明性プリズム３０の面と反射部材４０との少なくとも一方での反射を利用した反射回数が異なる２種以上の光路で室内天井側に向けて光を出射すると共に、角度が所定角度未満の光が入射した場合、第３の辺３０ｃを透過させる。【選択図】図１
