Patent ID: 7973482

Claim:
A high-pressure discharge lamp comprising: an elongated discharge vessel, as sole bulb, that defines an axial axis of symmetry and that is closed at two ends by seals and encloses a discharge volume, two electrodes, whose shafts are connected to foils, being opposite one another on the axis, and that contains an ionizable filling made from mercury, inert gas and metal halides, and having supply leads that are connected to the electrodes via foils and that emerge at the ends of the discharge vessel, the lamp configured to be operated at a power of at least 1600 W, wherein the shafts are designed as pins with a diameter of 0.5 to 1.15 mm, and in which the halogen for the halides comprises the constituents iodine and bromine, use being made jointly of bromine and iodine, wherein the maximum bromine/iodine ratio is 1.45, wherein the filling comprises at least metal halides of mercury and from the group of the elements Cs and rare earth metals and additionally comprises metal halides of sodium and/or manganese, wherein the color rendition index of the lamp is at least 85, the light yield of the lamp is at least 90 lm/W, and the color temperature of the lamp lies between 3300K and 4800K.
