<p>The high-pressure discharge lamp comprises a sealed lamp vessel (1) having a quartz glass wall (2) enclosing a discharge space (3). Metal foils (4) are embedded in the wall, connected to electrode rods (6) projecting from the wall into the discharge space. The electrode rods (6) have a first part (7a) and a second part (7b) with a diameter of between 250 and 350 νm and at least an envelope (7c) made of rhenium. The second part, which is positioned within the wall (2), prevents premature failure of the lamp caused by leakage.</p> |
