ABSTRACT:
It is provided a ceramic vessel for a high pressure discharge lamp and for filling an ionizable luminous substance and a starter gas in the inner space of the vessel. The discharge vessel has a tubular central luminous portion, and a pair of tubular end portions protruding from both ends of said central luminous portion, respectively. Each of the end portions has a maximum wall thickness “1” of 0.5 times or larger and 0.9 times or smaller of the wall thickness “t” of the central luminous portion. A ceramic discharge vessel is thereby provided enabling for improving the luminous efficiency of the high pressure discharge lamp.
