HIGH-PRESSURE GAS-DISCHARGE LAMP

摘要

The invention relates to a high-pressure gas-discharge lamp, having at least one gastight fused press-seal (61, 62) between a glasslike material and molybdenum, wherein the molybdenum in the fused press-seal (61, 62) is at least partly exposed to an oxidizing environment and at least that part of the molybdenum (5) that is exposed to the oxidizing environment is covered with a coating, and the coating comprises at least one oxide from among Fethe invention relates to a high-pressure gas-discharge lamp,having at least one gastight fused press-seal between a glasslike material and molybdenum,wherein the molybdenum in the fused press-seal is at least partly exposed to an oxidizing environment and at least that part of the molybdenum that is exposed to the oxidizing environment is covered with a coating, and the coating comprises at least one oxide from among Fe2O3, Ta2O5, Nb2O5, Al2O3, SiO2, TiO2, ZrO2, HfO2, and/or one nitride from among TiN, ZrN, HfN, AlN, BN, and/or one carbide from among TiC, ZrC, HfC, VC, NbC, TaC, B4C.
