| 摘要 |
The invention relates to a novel operating circuit for a low-pressure discharge lamp 1 with early EOL detection via a measurement of the DC voltage between the electrodes 2, 3. In this case, an electrode interrogation can be carried out by checking a respective connection via the electrodes 2, 3 to a respective reference potential.
