  • the system for controlling light entrance is characterized, according to the invention, in that it further comprises a reflective surface extending on a window side along a part of the ceiling of the inner space, for reflecting daylight reflected back by the top surface of the slats and having reflected from the inner side of the pane, deeper, with respect to the window side, into the inner space.

  • the reflective surface can advantageously extend along the entire window side of the space, that is, the wall of the space in which windows are provided.

Abstract

La présente invention concerne un système permettant de contrôler l'entrée de la lumière dans l'espace intérieur d'un bâtiment. Ce système comprend un dispositif de protection du soleil de type store vénitien agencé le long d'un panneau de fenêtre d'un espace intérieur, la surface supérieure des lames étant conçue de façon que la lumière du jour incidente sur ces surfaces supérieures soit rétroréfléchie dans un plan passant par l'axe longitudinal de la lame et la direction de l'incidence. Selon cette invention, une surface de réflexion située d'un côté de la fenêtre le long d'une partie du plafond de l'espace intérieur, permet de réfléchir la lumière du jour reflétée par la surface supérieure des lames, et offre une réflexion en provenance de l'intérieur du panneau, plus profonde, compte tenu du côté de fenêtre concerné, dans l'espace intérieur. Cette invention concerne aussi un procédé permettant de contrôler l'entrée de la lumière dans l'espace intérieur d'un bâtiment.
