| 摘要 |
An atomic spectral lamp having a housing (10, 16) which consists at least partially of electrically conductive walls (10), which housing contains an impact gas at a pressure less than atmospheric pressure in order to produce a gas discharge and which has a light-outlet window (16) with an electrode (11) which is arranged inside the housing, is electrically insulated from said housing, contains a cavity (13) for holding the material (15) which is to be excited to spectral emission and having connections for the application of an electrical potential to the electrode (11) and to the electrically conductive wall parts, which is distinguished in that only a single electrode (11) is provided in the housing (10, 16), and its electrical potential is lower than that of any of the electrically conductive wall parts (10). <IMAGE>
