Abstract (en)

Headlamp system comprises a sensor system (80) which releases a signal depending on a characteristic value of the relative air moisture in the inner chamber (15) of the headlamp (10). The sensor system controls and/or regulates a conveying unit (70) using the released signal. Preferred Features: The sensor system comprises an illuminating diode and an optical receiver. A heat source (50) is arranged in the inner chamber of the headlamp and is thermally connected to a light source (40).

Abstract (de)

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.
