Abstract

Die Erfindung betrifft ein Scheinwerfersystem mit mindestens einem Scheinwerfer, dessen Innenraum zumindest bereichsweise mittels mindestens einer Lichtscheibe gegen die Umgebung abgegrenzt ist, mit mindestens einer Lumineszenzdiode als Lichtquelle und mit mindestens einer innerhalb des Scheinwerfers angeordneten Fördervorrichtung. Dazu umfasst das Scheinwerfersystem ein Sensorsystem. Das Ausgabesignal des Sensorsystems ist abhängig von einem Kennwert der relativen Luftfeuchtigkeit im Innenraum des Scheinwerfers. Außerdem steuert und/oder regelt das Sensorsystem mittels des Ausgabesignals die Fördervorrichtung.
Mit der vorliegenden Erfindung wird ein Scheinwerfer mit Leuchtdioden als Lichtquellen entwickelt, bei dem eine Beeinträchtigung der Leuchtstärke durch Kondensat schnell und mit geringem Energieeinsatz beseitigt werden kann.
