Abstract

Die Erfindung betrifft eine Zweifaden-Halogenglühlampe für einen Kraftfahrzeugscheinwerfer. Zur Verringerung der durch die Wendelhalterung verursachten Lichtabschattungseffekte ist mindestens einer der Stromzuführungsdrähte (8) mit einem aus der gemeinsamen Ebene der Stromzuführungsdrähte (7, 8, 9) herausragenden und an der Hauptwendel (5) vorbeigeführten Abschnitt (8a) versehen, wobei dieser Abschnitt (8a) so gestaltet ist, dass Lichtstrahlen, die von der Hauptwendel (5) senkrecht zu ihrer Wendelachse emittiert werden, nicht von dem Stromzuführungsdraht (8) behindert werden.

Figure imgaf001
The invention relates to a two-filament halogen incandescent lamp for a motor vehicle headlight. To reduce the Lichtabschattungseffekte caused by the helical mount at least one of the power supply wires (8) with a from the common plane of the power supply wires (7, 8, 9) protruding and past the main coil (5) guided section (8a), this section ( 8a) is designed so that light rays emitted by the main coil (5) perpendicular to its helix axis are not obstructed by the power supply wire (8).
