Abstract
Improvements introduced in the manufacture of sodium vapor discharge lamps containing a rare gas mixture composed substantially of neon and in which the inner side of the discharge vessel is a borate glass which substantially does not discolour, characterized by the fact that that the borate glass has the following composition: (see graphic) with the condition that BaO = 40 to 65% by weight SiO2 + B2O5 = 15 to 30% by weight SiO2 + Al2O3 = 5 to 25% by weight.
