Abstract
A synchronous switching device. The switching device includes a common electrode, distributed electrodes, voltage converters and a signal generator. The distributed electrodes are aligned in a straight line facing the common electrode. Each distributed electrode has a length smaller than the common electrode. Each voltage converter is electrically coupled to the common electrode as well as one distributed electrode. All voltage converters are electrically coupled to the signal generator. A first panel, a second panel and two side panels together form a planar lamp with a hollow space inside. A layer of fluorescent coating is deposited on the interior surface of the first and the second panel. The distributed electrodes and the common electrodes are mounted on each side of the hollow space. Through high voltage synchronous signals generated by the signal generator and the voltage converters, the planar fluorescent lamp is lit.
