Title

(FR) FENÊTRE D’ÉCLAIRAGE DE PLAFOND
(JA) 天井照射窓
Abstract
(EN) 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).
(FR) L’invention concerne une fenêtre d’éclairage de plafond (1) dotée d'un prisme transparent (30), et un élément réfléchissant (40) étant disposé sur un deuxième bord (30b) du prisme transparent (30). En outre, le prisme transparent (30) est installé de manière à permettre à la lumière incidente sur ce dernier selon un certain angle, par rapport à une ligne normale à des première et seconde plaques transparentes (10a, 10b), qui est au moins égal à un angle prescrit d’être réfléchie au niveau d'un troisième bord (30c) à l'aide d'un angle critique. De plus, lorsque la lumière est incidente selon un angle au moins égal à l'angle prescrit par rapport à la ligne normale, le prisme transparent (30) émet la lumière vers un côté plafond intérieur à l'aide d'au moins deux types de trajet optique ayant différents nombres de réflexions, à l'aide d'une réflexion au niveau de la surface du prisme transparent (30) et/ou de l'élément réfléchissant (40), et lorsque la lumière est incidente selon un angle inférieur à l'angle prescrit, le prisme transparent laisse passer la lumière à travers le troisième bord (30c).
(JA) 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。
