<p>The high-pressure gas discharge lamp (1) comprises a lamp vessel (2) having a wall (3) which is exposed to a wall load of at least 30 W/cm2 during operation of the lamp, and a discharge space (4) in which a pair of electrodes (5) is disposed. The discharge space (4) has a filling which comprises mercury, argon, and halides (not fluorides) of tin and indium, to which filling an alkali metal halide is added, the alkali metal being potassium, rubidium, or cesium, and the halide being chlorine, bromine, or iodine. The high-pressure discharge lamp (1) according to the invention has an improved resistance against corrosion and crystallization of the quartz glass wall (3).</p> |
