Abstract

Es ist eine Lichtleitereinrichtung (10; 70, 72, 74, 76, 78, 80) angegeben mit einem Lichtleitelement (12), welches durch eine erste Hauptfläche (14) und eine zu dieser parallel beabstandete zweite Hauptfläche (22) begrenzt ist, und mit einer Reflexionseinrichtung (24), welche auf der Seite der zweiten Hauptfläche (22) des Lichtleiterelements (12) angeordnet ist und mittels welcher Licht wenigstens in Richtung auf das Innere des Lichtleiterelements (12) reflektierbar ist. Die Reflexionseinrichtung (24) umfasst Materialinseln (26) aus einem vorzugsweise transparenten Reflexionsmaterial. Außerdem sind eine Beleuchtungsvorrichtung (42; 100), welche eine derartige Lichtleitereinrichtung (10; 70, 72, 74, 76, 78, 80) ) umfasst, und ein Verfahren zur Herstellung der Lichtleitereinrichtung (10; 70, 72, 74, 76, 78, 80) angegeben.
