A driving circuit and lighting equipment using the same are provided. The driving circuit includes a first power receiving terminal, a second power receiving terminal and a power conversion unit. The first power receiving terminal receives an alternating current (AC) input signal. The second power receiving terminal is electrically coupled to a predetermined potential. The power conversion unit is electrically coupled to the first and second power receiving terminals for transforming the AC input signal into corresponding two AC output signals of different phases, wherein the two AC output signals are with the same current.
