Abstract (en)
[origin: WO2011012301A1] The present invention relates to a light guiding device for guiding sunlight into the interior of a building, with a number of movably mounted light deflecting areas, which can be directed according to the position of the sun by a control device. According to the invention, the light deflecting areas of the light guiding device are formed by deflecting slats which are arranged in the form of rows, can be pivoted about pivot axes approximately parallel to one another and are mounted on a slat support, which is rotatable about an axis of rotation approximately perpendicular to the direction of the pivot axes.
