Abstract

The method involves mechanically moving the lamp with a suitable electromagnetic or electric motor device after a certain period following lamp switch-off or when starting the vehicle. The electromagnetic or electric motor device forms part of a light range regulator or a lamp positioning device.

Description

Die Erfindung betrifft ein Verfahren zur Reduzierung des Quecksilberkondensats auf den Elektroden einer Xenonlampe in einem Kraftfahrzeug.The invention relates to a method for reducing the mercury condensate the electrodes of a xenon lamp in a motor vehicle.

Beim Abkühlen einer Xenonlampe in einem Kraftfahrzeug bilden sich Quecksilbertropfen auf den Elektroden, die den Zündspannungsbedarf der Lampe deutlich erhöhen.When a xenon lamp in a motor vehicle cools down Drops of mercury on the electrodes, which the ignition voltage of the lamp increase significantly.

Es ist die Aufgabe der Erfindung, die Menge des Quecksilberkondensats auf den Elektroden auf einfache und kostengünstige Weise zu reduzieren.It is the object of the invention to determine the amount of mercury condensate Reduce electrodes in a simple and inexpensive way.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lampe nach einer vorgegebenen Zeit nach dem Abschalten der Lampe oder beim Starten des Kraftfahrzeug durch eine Vorrichtung mechanisch bewegt wird.This object is achieved in that the lamp after a predetermined time after switching off the lamp or when starting the Motor vehicle is mechanically moved by a device.

Die Lampe wird nach dem Abschalten (nach mehr als 30 s) und/oder beim Starten des Kraftfahrzeugs bei abgeschaltetem Licht bewegt (beschleunigt). Durch diese Beschleunigung werden die besonders dicken Quecksilbertropfen von den Lampenelektroden abgeschüttelt.The lamp comes on after switching off (after more than 30 s) and / or when starting of the motor vehicle moves (accelerates) with the lights switched off. Through this The particularly thick drops of mercury are accelerated by the Lamp electrodes shaken off.

Besonders vorteilhaft ist, wenn diese Bewegung von bereits im Kraftfahrzeug vorhandenen Einrichtungen z. B. vom Leuchtweiteregler oder von einer mechanischen Lampenpositioniereinrichtung zum Umschalten zwischen Fern- und Abblendlicht zusätzlich ausgeführt wird. Vorteilhaft ist auch, wenn die Lampe hierbei über den gesamten Schwenkbereich dieser Einrichtung aufwärts und abwärts bewegt wird.It is particularly advantageous if this movement is already in the motor vehicle existing facilities z. B. from headlamp leveling or from one mechanical lamp positioning device for switching between remote and Low beam is also executed. It is also advantageous if the lamp is used here over the entire swivel range of this device up and down is moved.

Vorteilhaft ist zudem, den Zeitpunkt für die Bewegung der Xenonlampe so zu wählen, daß einerseits möglichst alles Quecksilber kondensiert ist, andererseits die Lampe aber noch so warm ist, daß das Quecksilber durch die Lampenbewegung von den Elektroden geschleudert werden kann. Der günstigste Zeitpunkt hierfür ist nach einer Abkühlphase von ungefähr einer Minute erreicht.It is also advantageous to choose the time for the movement of the xenon lamp in such a way that on the one hand everything mercury is condensed, on the other hand the lamp but is still so warm that the mercury from the lamp movement Electrodes can be thrown. The best time to do this is after Cooling phase of approximately one minute reached.
