| abstract | PROBLEM TO BE SOLVED: To provide a lamp of a type which is easy to manufacture and has a configuration in which there is no danger of leakage due to a ceramic sealing compound for directly connecting a first part of a current conductor to a lamp vessel. thing. The lamp has a ceramic lamp vessel (1) having a filling of a rare gas and a metal halide. The current conductors (2, 3) supporting the electrodes (4, 5) in the discharge vessel (1) enter the discharge vessel (I) via the ceramic sealing compound (6) in a gas-tight manner. At least one of the current conductors (2, 3) is halogen-resistant, selected from tungsten silicide, molybdenum aluminide, molybdenum boride, pentamolybdenum tricide and a combination of at least two of these intermetallic compounds. A first part (21, 31) is provided in the lamp vessel (1). These compounds have a coefficient of thermal expansion corresponding to that of the discharge vessel (1). Thus, when the ceramic sealing compound (6) extends beyond the first portion (21, 31), the discharge vessel can be prevented from starting to leak. As a result of their coefficient of thermal expansion, the intermetallic compounds cause the second portions (22, 32) of the current conductors (2, 3), which are surrounded by the ceramic sealing compound (6) in a gas-tight manner. It can also be configured. |
