Abstract

Die Erfindung betrifft eine Lichtleitvorrichtung zum Leiten von Licht. Die Lichtleitvorrichtung weist einen Lichtleiter, eine Lichteinkopplungseinrichtung und eine Lichtauskopplungseinrichtung auf. Das Licht innerhalb des Lichtleiters breitet sich über eine Reflexion an Grenzflächen des Lichtleiters aus. Die Auskopplung des Lichts aus dem Lichtleiter ist mittels der Lichtauskopplungseinrichtung nach einer vorher festgelegten Anzahl an Reflexionen des Lichts an Grenzflächen des Lichtleiters vorgesehen. Es ist ebenfalls eine Anzeigevorrichtung, insbesondere eine nah am Auge vorgesehene Anzeigevorrichtung, vorgesehen, die eine Beleuchtungseinrichtung mit wenigstens einer Lichtquelle, wenigstens eine räumliche Lichtmodulationseinrichtung, ein optisches System und eine Lichtleitvorrichtung aufweist.
