Electric discharge lamp
An electric discharge lamp comprising: a light-transmissive ceramic lamp vessel ( 1 ); a first and a second current conductor ( 2,3 ) entering the lamp vessel ( 1 ), and each supporting an electrode ( 4,5 ) in the lamp vessel ( 1 ); an ionizable filling comprising a rare gas and a metal halide in th...

| Zusammenfassung: | An electric discharge lamp comprising: a light-transmissive ceramic lamp vessel ( 1 ); a first and a second current conductor ( 2,3 ) entering the lamp vessel ( 1 ), and each supporting an electrode ( 4,5 ) in the lamp vessel ( 1 ); an ionizable filling comprising a rare gas and a metal halide in the lamp vessel ( 1 ); at least the first current conductor ( 2 ) within the lamp vessel ( 1 ) being halide-resistant, characterized in that the first current conductor ( 2 ) at least substantially comprises a material with an at least substantially isotropic coefficient of thermal expansion, said material preferably being chosen from the group of pentamolybdenum boride disilicide, pentamolybdenum diboride silicide, or a combination of these two materials. |
