des Ersatzmetalls nicht erschwert werden.
Das Ersatzmetall muß die beim Einschmelzen des Stromzuführungsleiters
in den Glassockel auftretenden Schmelztemperaturen
von ca. 1.200°C aushalten.
Das Ersatzmetall muß eine gute elektrische Leitfähigkeit haben, um
die Stromzufuhr in das Innere der Leuchtmittellampe zu gewährleisten.

Eine Aufgabe der Erfindung ist es daher, eine Stiftsockel-Niedervolt-Halogenlampe der eingangs genannten Art zu schaffen, deren Stromzuführungsleiter aus einem billigeren Metall besteht und dennoch die Anforderungen gut erfüllt, die an einen Stromzuführungs-leiter dieser Lampe gestellt sind. Die erfindungsgemäße Stiftsockel-Niedervolt-Halogenlampe ist, diese Aufgabe lösend, dadurch gekennzeichnet, daß Stromzuführungsleiter aus einem Edelstahl, der austenitisch ist und Zusätze von Cr und/oder Ni enthält, besteht, oder daß der Stromzuführungsleiter einen Trägerkern aus einem nicht austenitischen, Legierungszusätze enthaltenden Kohlenstoffstahl aufweist und der Trägerkern rundum mit einem Mantel aus Nickel versehen ist.An object of the invention is therefore a pin base low-voltage halogen lamp to create of the type mentioned, whose Power supply conductor is made of a cheaper metal and yet well meets the requirements for a power supply conductor this lamp are put.

Wegen des Stahlmaterials ist das Metall des Stromzuführungsleiters sehr viel billiger, z.B. 20 % billiger, als eine zu 98 % aus Nickel bestehende Legierung oder reines Nickel. Umfangreiche Versuche haben gezeigt, daß der Stromzuführungsleiter trotz des Stahlmaterials die Anforderungen hinsichtlich Fertigung, Glasschmelztemperatur, elektrische Leitfähigkeit, Wärmeleitfähigkeit, Betriebstemperatur und Korrosionsbeständigkeit gut erfüllt. Der Stromzuführungsleiter weist aufgrund des Stahlmaterials bzgl. elektrischer Leitfähigkeit und Wärmeleitfähigkeit etwas schlechtere Werte auf als der bekannte Stromzuführungsleiter mit der NiMn-Legierung; diese Werteverschlechterung wird in Kauf genommen, da der erfindungsgemäße Stromzuführungsleiter die gestellten Anforderungen trotzdem noch gut erfüllt. Die Erfindung besteht, mit anderen Worten, in der Anwendung der angegebenen speziellen Stahlmaterialien für den Stromzuführungsleiter der Stiftsockel-Niedervolt-Halogenlampe.Because of the steel material, the metal is the power supply conductor much cheaper, e.g. 20% cheaper than 98% nickel Alloy or pure nickel.

Es handelt sich hier um eine Leuchtmittellampe, die eine Niederleistungslampe bis 50 W ist und eine Stiftsockel-Niedervolt-Halogenlampe ist. Da das Stahlmaterial eine schlechtere Wärmeleitfähigkeit hat, ist diese Leuchtmittellampe-Gestaltung besonders geeignet, da sich bei dieser die Folgen der schlechteren Wärmeleitfähigkeit recht gut beherrschen lassen. Eine Stiftsockel-Niedervolt-Halogenlampe liegt auch im Falle einer Kaltlichtreflektorlampe vor.It is a light bulb that is a low-power lamp up to 50 W and a pin base low-voltage halogen lamp is. Because the steel material has poorer thermal conductivity has, this lamp design is particularly suitable because the consequences of poorer thermal conductivity are right let it master well.
