Abstract
A system for driving multiple lamps includes a transformer circuit, a filter and steady-flow circuit, and a light source. The transformer circuit includes a first output end for outputting a first AC signal, and a second output end for outputting a second AC signal. The filter and steady-flow circuit includes plural filter and steady-flow circuit units that are respectively connected to the first output end for suppressing harmonic signal associated with the first AC signal, smoothing sinusoidal shape of the first AC signal, and transmitting plural third AC signals that have substantial same current values. The light source includes a plurality of lamps, each of which having one end is connected to one of the filter and steady-flow circuit units, and is driven by the third AC signal. A method for driving multiple lamps is also disclosed.
