Durch die Ausstattung mit dem erfindungsgemäßen Einfachgewickel und durch das Zusammenwirken mit dem Reflektor des Kraftfahrzeugscheinwerfers ist mit der erfindungsgemäßen Halogenglühlampe eine homogenere Beleuchtung als mit den vorgenannten, bisher üblichen Halogenglühlampen erzielbar. Die Beschränkung der Länge des erfindungsgemäßen Einfachgewickels auf einen Bereich von 4,0 mm bis 6,5 mm gewährleistet durch das Zusammenwirken mit dem Reflektor des Kraftfahrzeugscheinwerfers eine gerichtete Lichtemission und einen wohldefinierten Lichtkegel. Das Einfachgewickel der erfindungsgemäßen Halogenglühlampe besitzt eine um das Drei- bis Vierfache höhere Windungszahl und einen deutlich geringeren Abstand zwischen den einzelnen Windungen als das Sekundärgewickel der doppelt gewendelten Glühwendel der bisher üblichen Halogenglühlampen für Scheinwerfer von Kraftfahrzeugen mit einer Bordnetz-Nennspannung von 24 Volt. Vorteilhafterweise ist das Einfachgewickel der erfindungsgemäßen Halogenglühlampe mit mindestens 20 Windungen ausgestattet, die sich gleichmäßig über die Länge des Einfachgewickels verteilen, um eine möglichst homogene Beleuchtung zu erzielen.In the case of the halogen incandescent lamp according to the invention, the at least one incandescent filament is designed as a single wound whose dimensions and / or geometry are matched to an operating voltage of at least 20 volts, the length of the single wound coil having a value in the range from 4.0 mm to 6.5 mm. By equipping with the simple winding according to the invention and by the interaction with the reflector of the motor vehicle headlight, a more homogeneous illumination can be achieved with the halogen incandescent lamp according to the invention than with the previously known halogen incandescent lamps. The limitation of the length of the single wrap invention to a range of 4.0 mm to 6.5 mm ensured by the interaction with the reflector of the motor vehicle headlight directional light emission and a well-defined beam of light. The Einfachgewickel the halogen incandescent lamp according to the invention has a three to four times higher number of turns and a much smaller distance between the individual turns than the Sekundärgewickel the double-spiraled filament of the usual halogen lamps for headlights of motor vehicles with a nominal voltage of 24 volts. Advantageously, the simple winding of the halogen incandescent lamp according to the invention is equipped with at least 20 turns, which are distributed uniformly over the length of the single winding in order to achieve the most homogeneous possible illumination.

Um trotz des dünneren Drahtes eine hohe Erschütterungsfestigkeit zu gewährleisten, sind die Glühwendelenden der erfindungsgemäßen Halogenglühlampe vorteilhafterweise mit Stützmitteln versehen. Als Stützmittel eignen sich vorzugsweise Stützwendeln oder aus Molybdänfolie bzw. Molybdänband gefertigte Röhrchen, die die ungewendelten Enden des Einfachgewickels umschließen.In contrast to the 12V halogen incandescent lamps described above as state of the art, the halogen incandescent lamp according to the invention, due to the higher operating voltage, as a filament has a single winding, which is made of a thinner and a wire about twice as long as the single winding of the 12V halogen incandescent lamp , In order to ensure a high vibration resistance despite the thinner wire, the filament ends of the halogen incandescent lamp according to the invention advantageously provided with support means.

Der Durchmesser des zur Glühwendelherstellung verwendeten Drahtes liegt vorteilhafterweise zwischen 0,11 mm und 0,14 mm, um einerseits den Wendelwiderstand an die gewünschte Leistungsaufnahme der erfindungsgemäßen Halogenglühlampe anzupassen und andererseits ein räumlich kompaktes Einfachgewickel als Glühwendel zu ermöglichen.Advantageously, the Einfachgewickel of the halogen incandescent lamp according to the invention has at least 20 turns and an outer diameter between 1.4 mm and 2.0 mm, so that the halogen incandescent lamp according to the invention despite the comparatively long wire, which is used for the production of the filament, has a spatially compact single winding as filament , The diameter of the wire used for Glühwendelherstellung is advantageously between 0.11 mm and 0.14 mm, on the one hand to adapt the coil resistance to the desired power consumption of the halogen incandescent lamp according to the invention and on the other hand to enable a spatially compact single winding as a filament.
