摘要

A system for controlling light entrance into an inner space of a building, comprising a Venetian blind type sun protection device arranged along a pane of a window of the inner space, the top surfaces of the slats thereof being so designed that daylight incident on the top surface is reflected back in a plane through the longitudinal axis of the slat and the direction of incidence. According to the invention, there is provided 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 inside of the pane, deeper, with respect to the window side, into the inner space.
