Abstract

Improvements introduced in the manufacture of sodium vapor discharge lamps containing a mixture of rare gases and containing inside a layer of a glass consisting substantially of boron trioxide, aluminum oxide and alkaline earth oxides, characterized by that the glass layer has the following composition: (see graphic) alkaline oxide (R2O) 0-3% by weight, in which the alkaline earth oxide (SO) is 60-70% by weight and SiO2 + R2O3 is 30-40% by weight.
