Patent ID: 7589468

Claim:
A high-intensity discharge lamp comprising an elongated discharge vessel surrounded by an outer envelope and having a wall which encloses a discharge space comprising an ionizable filling including an inert gas, wherein at both ends in said discharge space an electrode is arranged between which a discharge arc can be maintained along a discharge path, wherein one end of the discharge vessel is mounted in a mounting base, said lamp comprising a substantially band-shaped light-shielding conductive strip extending laterally from the discharge oath and provided with one of the discharge vessel or the outer envelope, and a lead-back conductor supplying current from the mounting base to the electrode at the other end of the discharge vessel, characterized in that, seen in cross section, the lead-back conductor is positioned within a sector defined by two lines through a center of the discharge vessel and the edges of said strip, further comprising a conductive antenna extending laterally from the discharge oath and, seen in cross section, positioned within said sector or substantially on one radial line through the center of the discharge vessel wherein the antenna or the lead-back conductor is integrated with said strip.
