Abstract

Beschrieben wird eine Vorrichtung zur Lichtumlenkung sowie und -ausblendung für den stationären Einsatz bei einer transluzenten Gebäudefassade (F) zur gezielten Beleuchtung eines Innenraumes mit wenigstens einem transluzenten optischen Element (C), das eine eben ausgebildete Lichteintrittsseite (A) aufweist sowie eine Lichtaustrittsseite (D) vorsieht, die von einer ersten gekrümmten Grenzfläche sowie zumindest von einer zweiten Grenzfläche begrenzt ist, wobei die Krümmung der ersten Grenzfläche derart ausgebildet ist, dass Lichtstrahlen, die aus einem ersten Raumwinkelbereich (B) auf die Lichteintrittsseite (A) auftreffen und in das optische Element einkoppeln im Wege der Totalreflexion an der ersten Grenzfläche auf den Bereich der zweiten Grenzfläche konzentriert werden und dass Lichtstrahlen, die aus einem zweiten Raumwinkelbereich auf die Lichteintrittsseite auftreffen und in das optische Element einkoppeln durch die erste Grenzfläche aus dem optischen Element austreten.
Die Erfindung zeichnet sich dadurch aus, dass die zweite Grenzfläche ebenfalls stetig gekrümmt ausgebildet ist und dass die erste und die zweite Grenzfläche nahtlos und mit einem stetigen Krümmungsverhalten aneinander anschließen.
