ABSTRACT:
An inverter for driving at least one light-emitting unit includes a switching circuit, an electric-isolated circuit and a transforming circuit. The switching circuit generates at least one switching signal according to a DC signal and at least one switching control signal. The electric-isolated circuit has an electric-isolated side and a non-electric-isolated side, which is electrically connected to the switching circuit electrically and generates a first power signal according to the switching signal. The transforming circuit is electrically connected to the electric-isolated side of the electric-isolated circuit, and generates a second power signal to drive the light-emitting unit according to the first power signal.
