OPERATING DEVICE FOR GAS DISCHARGE LAMPS WITH DETECTION OF FILAMENT BREAKAGE |
| 摘要 |
Disconnection device for an electronic operating device for gas discharge lamps. The filament breakage of a lamp is evaluated by detecting the current through a component which flows through the filaments. This is performed either by detecting this current with the aid of an optocoupler or by measuring the phase of the load circuit current. |
