Abstract

Es gibt einen Stromzuführungsleiter 4, der für eine einen Glassockel 2 aufweisende Leuchtmittellampe vorgesehen ist und der aus einer Ni enthaltenden Legierung besteht. Dabei ist es erwünscht, wenn die Legierung des Stromzuführungsleiters einerseits wesentlich billiger als Nickel ist und andererseits doch die Anforderungen gut erfüllt, die an einen Stromzuführungsleiter für eine Leuchtmittellampe gestellt sind. Dies ist erreicht, indem die Legierung eine CuNi-Legierung ist, die 10 - 30 Gew.% Ni und 70 - 90 Gew.% Cu enthält. Dieser Stromzuführungsleiter erfüllt trotz des hohen Kupfergehalts die Anforderungen hinsichtlich Fertigung, Glasschmelztemperatur, elektrische Leitfähigkeit, Wärmeleitfähigkeit, Betriebstemperatur und Korrosionsbeständigkeit gut.

Figure 00000001
There is a power supply conductor 4, which is provided for an illuminant lamp having a glass base 2 and which consists of an alloy containing Ni. It is desirable here if the alloy of the power supply conductor is on the one hand much cheaper than nickel and on the other hand nevertheless satisfies the requirements placed on a power supply conductor for a lamp. This is achieved by the alloy being a CuNi alloy which contains 10-30% by weight of Ni and 70-90% by weight of Cu. Despite the high copper content, this power supply conductor meets the requirements with regard to production, glass melting temperature, electrical conductivity, thermal conductivity, operating temperature and corrosion resistance well.
