Electronic circuits for detecting filament breakage in gas discharge lamps |
摘要 |
Disconnection device for an electronic operating device for gas discharge lamps. The DC component is evaluated at a coupling capacitor (C5) specifically via a filament. Disconnection is performed in the event of filament breakage. In addition, the AC component of the generator output (O) can be monitored via a second filament, and disconnection can therefore also be performed in the event of breakage of the second filament.
