PROBLEM TO BE SOLVED: To provide a light collection device high in degree of freedom of fitting timing or fitting position, and capable of sufficiently collecting sunlight to a room depth of a room, even in a case where sun elevation is high.SOLUTION: A louver 1 reflects sunlight to irradiate an indoor ceiling surface 15. The louver 1 includes a plurality of vanes 20 aligned in vertical direction to outside, and on the upper surface of the vane 20, a reflection surface 30 reflecting sunlight is provided. The reflection surface 30 is divided into a plurality of reflection regions 30A-30F for each sun elevation from an indoor side toward an outdoor side. The reflection regions 30A- 30F cope with lower sun elevation as arranged toward the indoor side from the outdoor side.SELECTED DRAWING: Figure 3 【課題】取付け時期や取付け位置の自由度が高く、かつ、太陽高度が高い場合であっても、太陽光を室内の室奥に十分に採り入れることができる採光装置を提供すること。【解決手段】ルーバー１は、太陽光を反射して屋内の天井面１５に照射する。ルーバー１は、屋外に上下方向に並んで配置された複数の羽板２０を備え、これら羽板２０の上面には、太陽光を反射する反射面３０が設けられている。この反射面３０は、屋外側から屋内側に向かって、太陽高度毎に複数の反射領域３０Ａ〜３０Ｆに分割され、複数の反射領域３０Ａ〜３０Ｆは、屋内側に配置されるものほど、低い太陽高度に対応する。【選択図】図３
