Abstract
A light fixture includes a CCFL and a driving circuit. The driving circuit includes a first voltage converter and a high-voltage inverter. The first voltage converter provides a DC voltage signal according to a power signal. The high-voltage inverter comprises a second voltage converter and a first transformer. The second voltage converter converts the DC voltage signal into an AC voltage signal. The first transformer is corresponding to the first CCFL and includes a first primary winding circuit and a first secondary winding circuit. The first primary winding circuit has a first input voltage signal in response to the AC voltage signal. The first secondary winding circuit is coupled with the first input voltage signal to generate a first output voltage signal for driving the first CCFL. The first primary and secondary winding circuits belong to a primary-side circuit and receive the same ground voltage signal.
