Electrode feed lines made from a molybdenum/tungsten alloy and lamp having such feed lines

A feed line for an electric lamp is formed from an alloy of tungsten and molybdenum. The feed line has a rate of thermal expansion or contraction which is approximated to that of the glass which forms the bulb. This minimises the stress resulting from the mismatch due to expansion/contraction betwee...

Beschreibung
Zusammenfassung:	A feed line for an electric lamp is formed from an alloy of tungsten and molybdenum. The feed line has a rate of thermal expansion or contraction which is approximated to that of the glass which forms the bulb. This minimises the stress resulting from the mismatch due to expansion/contraction between the two materials. The composition of the alloy in addition reduces oxidation and the impairment of the feed line.
