ABSTRACT:
A discharge lamp having an emission part with a roughly spherical external shape and tube arms extending from opposite sides of the emission part, hermetically sealing parts formed on an end of each robe arm, and a lead pin extending parallel to a longitudinal axis of the tube arm, a tip of each lead carrying an electrode in the emission part, so that a pair of electrodes are arranged opposite one another in the emission part. Within each babe arm, in the vicinity of the emission part, a plate-shaped holding part which is made of a metal with a high melting point and through which the lead pin penetrates, is arranged roughly perpendicularly to the lead pin and serves for positioning of the electrodes.
