Abstract

The choke device has an inverter (1) with a pair of transistor switches (17,18) connected in series with a DC source (Ubus) in a push-pull circuit, the inverter linked to a load circuit (3) containing a gas discharge lamp (4) and a series resonance circuit (22) via a coupling capacitor (2) in parallel with a high-impedance resistor (12). A sensor circuit (6), for detecting lamp malfunction and the voltage applied to the lamp, has a voltage divider (7) in parallel with the lamp filaments (8,9) and the resonance capacitor (5), its center-tap (11) coupled to an evaluation circuit (13). An independent claim for a method for detection of lamp malfunction and the lamp voltage in a choke device for a gas discharge lamp is also included.
