摘要： In a high-pressure gas discharge lamp, particularly a high-pressure sodium vapor lamp, comprising a tubular discharge vessel being made of a ceramic material and including electrodes and a filling and ceramic plug elements for closing the end regions of the discharge vessel, receiving a current lead-in connecting the electrode with an outer source of supply voltage, wherein at least one of the plug elements is built up with surface elements of different height levels and determining a cold chamber for receiving the metal additive, the distance between the surface of the metal additive and the current lead-in measured as length of the way determined on the surface elements is at least 4 mm.
