High-pressure sodium discharge lamp comprising a discharge arc shielding means

In the high-pressure sodium discharge lamp according to the invention, the electrodes (17) are surrounded by a hollow cylindrical body (18), which limits an annular space accommodating an electron emitter (19). The cylindrical body (18 l ) extends against the current conductor (6) supporting the ele...

description In the high-pressure sodium discharge lamp according to the invention, the electrodes (17) are surrounded by a hollow cylindrical body (18), which limits an annular space accommodating an electron emitter (19). The cylindrical body (18 l ) extends against the current conductor (6) supporting the electrode (17). Means for screening the electron emitter (19) are provided at the end of the annular space facing the electrode tip (20). A shield (21) extends from against the electrode tip (20) laterally beyond the hollow cylindrical body (18).
