Abstract: The invention relates to a blended light lamp (1) having an incandescent lamp (2) and a gas discharge lamp (3), a rectifier (4), an energy storage means (5) and an ignition device (6). The high-pressure discharge has an operating voltage of 180 V, which can be achieved by filling a discharge vessel of the gas discharge lamp (3) with, in particular, an amount of mercury of 153 micromole/cm3. In this way a high total luminous flux can be obtained in the operating state.

Abstract: The invention relates to a high-pressure gas discharge lamp, particularly a motorcar lamp, comprising a bulb including at least two neck portions and a vacuum-tight discharge vessel of quartz glass, at least two electrodes projecting into the discharge vessel, and a filling in the discharge vessel which, in the operating state, is in a discharge state. Such lamps are used, in particular, in headlights of motorcars. In order to ensure that the arc of the high-pressure gas discharge lamp generates a higher luminescence in a small area, and the lamp can be used as a light source in motorcar headlights, the discharge vessel of the high-pressure gas discharge lamp in accordance with the invention encloses a discharge space having a width B below 4 mm and a length C below 8 mm, and the filling comprises NaI, ScI3, Xe, ZnI3 and is free of Hg. Surprisingly it has been found that the use ZnI2 in the filling causes the arc to generate a higher luminescence in the area of the arc axis per dimension of the arc.
