Abstract (en)

[origin: WO2009147058A1] The high-pressure discharge lamp has a ceramic discharge vessel with an aspect ratio of at least 1.5. For operation with acoustic resonances, a wall loading of the outer surface of the subregion which extends between the tips of the electrodes is from 28 to 40 W/cm2 and at the same time ensures a specific rated power of the entire outer surface of the discharge vessel, with exclusion of capillaries or stoppers, of 17 to 22 W/cm2.
