摘要： The present invention uses one or more transformers disposed between an inverter driver to drive a plurality of lamps. Each transformer has a first coil and a second coil magnetically coupled to each other. Each of the first and second coils has an input end and an output end. The input end of the first coil is operatively connected to the input end of the second coil for receiving an input current. Each of the first and second coils has a capacitor connected between the input and output ends. The output ends of the first and second coils are used to provide output current in two separate current paths. As such, the output end of a transformer can be separately connected to the input end of two lamps or two such transformers.

摘要： A lamp driving device for driving a lamp. A feedback circuit includes a voltage falling unit and a rectification circuit. The voltage falling unit provides a low voltage signal in response to a first DC power signal, a first AC power signal or a first driving power signal. The rectification circuit rectifies the low voltage signal to generate a feedback signal. The rectification circuit provides the feedback signal. A controller provides a control signal in response to the feedback signal. A first DC-to-AC converter transforms the first DC power signal to the first AC power signal in response to the control signal. A first voltage raising unit raises the voltage of the first AC power signal to generate the first driving power signal. The first raising unit provides the first driving power signal to a first end of the lamp, so that the lamp achieves the desired brightness stably.
