Abstract

Für den schnellen Anlauf einer Kfz-Metallhalogenid­ hochdruckentladungslampe (1) weist diese eine mög­ lichst kleine Quarzglasmenge und Elektroden auf, die für einen durch ein EVG zeitlich geregelten 5- bis 10fachen Anlaufstrom geeignet sind. Die Steuereinrich­ tung für das EVG bewirkt, daß die Grenzleistung der Lampe nicht überschritten wird. Darüber hinaus weist die Lampe an ihrer Oberfläche eine IR- und/oder UV-reflektierende (9) oder absorbierende (8) Beschich­ tung auf. Als zusätzliche Maßnahme kann das Quarz­ glas des Entladungsgefäßes mit einer IR- und/oder UV-reflektierenden oder absorbierenden Dotierung ver­ sehen sein. Mit einer Xenon-Füllung des Entladungs­ gefäßes 2 von mindestens 3 bar erzielt man den 90 %-Lichtstrom der Lampe schon bei ca. 1 sec. For the quick start of a motor vehicle metal halide high-pressure discharge lamp (1) has a poss very small amount of quartz glass and electrodes that for a 5 to 10 times the starting current are suitable. The tax institution device for the TOE causes the limit power of the Lamp is not exceeded. It also points the lamp has an IR and / or UV reflective (9) or absorbent (8) coating tion on. As an additional measure, the quartz Glass of the discharge vessel with an IR and / or UV reflecting or absorbing doping ver to be seen. With a xenon fill of the discharge vessel 2 of at least 3 bar is achieved 90% luminous flux of the lamp at approx. 1 sec.
