ABSTRACT:
Method of manufacturing a low-pressure mercury vapor discharge lamp (1) comprising a discharge envelope, the glass wall of which comprises at least an (alkaline earth) alkali constituent, a silicon dioxide-containing transparent layer (4) being produced on the inner wall of the discharge envelope.
In the method, such a direct current is maintained through the glass that the (positive) (alkaline earth) alkali ions move away from the inner wall and upon heating the said silicon dioxide-containing transparent layer (4) is produced.
