Patent ID: 7423379

Claim:
A high-pressure discharge lamp comprising: a discharge vessel ( 10 ) enclosing a discharge space ( 11 ) which contains an ionizable filling, the discharge vessel ( 10 ) having a first ( 2 ) and a second ( 3 ) mutually opposed neck-shaped portion provided with a pair of electrodes ( 6 , 7 ) protruding substantially into the discharge space ( 11 ), each electrode ( 6 , 7 ) being tubular over its entire length, at least one of the electrodes ( 6 , 7 ) being directly coupled at an end not arranged in the discharge space, to a rod ( 15 ) which is coupled at a distal end to a current-supply conductor ( 5 ), a melting-ceramic joint ( 21 ) being provided between the current-supply conductor ( 5 ), the rod ( 15 ) and a wall of the respective first ( 2 ) and a second ( 3 ) mutually opposed neck-shaped portions, thereby providing a gas-tight closure of the discharge space.
