The present invention relates to a high pressure sodium lamp comprising an evacuated cover (3) including a base part (7), an arc tube (5) comprising a first (13) and a second (15) electrode each being connected to the base part (7) via conductor members (17, 23). At least one conductor member (23) is arranged isolated by a shielding member (31) for preventing, during operation of the high pressure sodium lamp (1), the photo electronic stream from the at least one conductor member (23) to the arc tube (5). The lamp comprises a second arc tube.
La présente invention a trait à une lampe à vapeur de sodium à haute pression comprenant un couvercle sous vide (3) incluant une partie de base (7), un tube à arc (5) comprenant une première (13) et une seconde (15) électrode, chaque électrode étant connectée à la partie de base (7) via des éléments conducteurs (17, 23). Au moins un élément conducteur (23) est disposé de façon isolée par un élément de blindage (31) afin d'empêcher, pendant le fonctionnement de la lampe à vapeur de sodium à haute pression (1), le courant photoélectronique provenant du ou des éléments conducteurs (23) vers le tube à arc (5).
