ABSTRACT:
Systems and methods are provided for operating a fluorescent tube having a pair of filaments. The system comprises a transformer, an AC signal generator and a coupling device. The AC signal generator is connected to drive a primary AC signal onto the primary winding of the transformer and to thereby create a secondary AC signal on the secondary winding of the transformer. The secondary winding of the transformer is coupled between the filaments of the fluorescent tube at first terminals thereof. The coupling device is coupled between the filaments at second terminals thereof. The coupling device is switchable between a conducting state, wherein a majority of the current associated with the secondary AC signal is conducted by the coupling device, and a non-conducting state wherein a voltage drop across the coupling device is sufficient to cause a majority of the current associated with the secondary AC signal to arc between the filaments of the fluorescent tube.
