Abstract:
The present invention relates to a high pressure sodium lamp comprising an evacuated cover including a base part, an arc tube comprising a first and a second electrode each being connected to the base part via conductor members. At least one conductor member is arranged isolated by a shielding member for preventing, during operation of the high pressure sodium lamp, the photo electronic stream from the at least one conductor member to the arc tube. The lamp comprises a second arc tube.
