Abstract (en)

This shading and light directing system (1) includes two panes or sheets (2,3) in a new combination with a louvered or Venetian blind (12). This has the usual rise, fall and turning actions. The blind allows a room interior to be shaded. A novel feature is the light deflector (30) between the panes, which has rigid reflectors (31). Sunlight falling upon these is completely reflected into the room, providing diffuse illumination. The panes are preferably acrylic, polycarbonate or polymethyl methacrylate.

Abstract (de)

Es wird ein Beschattungs- und Lichtlenksystem (1) mit zwei Scheiben (2, 3) offenbart, welches gekennzeichnet ist durch die Kombination einer zwischen den-Scheiben (2, 3) angeordneten Lamellenjalousie (12) und einer zwischen den Scheiben (2, 3) angeordneten Lichtlenkeinrichtung (30). Die Lamellenjalousie (12) weist um ihre Längsachse verschwenkbare und wahlweise zusätzlich heb- und senkbare Lamellen (13) auf, mit der das Innere eines Raumes wahlweise beschattbar ist. Die Lichtlenkeinrichtung (30) weist zwischen den Scheiben (2, 3) verlaufende, starre Reflektoren (31) auf, mit denen auffallendes Sonnenlicht durch Totalreflektion in das Innere eines Raumes leitbar und als diffuses Licht zur Raumbeleuchtung nutzbar ist. <IMAGE>
