Abstract
PURPOSE: To provide a sealing method for an illuminating tube of quartz such asa high-voltage mercury lamp, by which method the oxygen-hydrogen flame method is replaced by the plasma arc method so that the quantity of H2 to be absorbed is reduced to prevent increase in the starting voltage for a discharge lamp and so that the danger concomitant with the prior art in production may be eliminated.
