HIGH-PRESSURE DISCHARGE LAMP |
摘要 |
The invention concerns high-pressure discharge lamps, whose electrodes have a sintered compact (5) containing lanthanum oxide acting as an electron emitter, and this compact is surrounded by an electrode coil (6). Sintered compact (5) contains at least 90 weight % lanthanum oxide. In this way, a high thermal stability of sintered compact (5) and a good ignition performance of the lamp are assured with only negligible blackening of the discharge vessel over the service life of the lamp. |
