Abstract

Improvements introduced in the manufacture of high pressure gas discharge lamps comprising a shell filled with a gaseous filling containing halogen and provided with electrodes of a high melting point material, for example tungsten or molybdenum, characterized in that at least 40 % of the surface of at least one of the electrodes, is covered with a layer of high melting material, resistant to halogen, but a small part of the surface of the electrodes is uncovered, so that it is free to receive the download (Machine-translation by Google Translate, not legally binding)
