Abstract

Um eine optimale Ausleuchtung des Lichtleiters bei einfacher konstruktiver Ausgestaltung zu erreichen, liegen die Reflexionsflächen (13, 14) quer zur Strahlrichtung des Leuchtmittels (8, 11) versetzt zueinander und schliessen, in Strahlrichtung gesehen, im wesentlichen lückenlos aneinander an. Dadurch tritt zwischen den einzelnen Reflexionsflächen (13, 14) keine Schattenbildung auf, so dass das vom Leuchtmittel (8, 11) ausgesandte Licht optimal ausgenutzt wird. Der Lichtleiter ist für Leuchten von Kraftfahrzeugen vorgesehen.
