Abstract: A dimming circuit includes a resonant unit, a rectification unit, a half-bridge output unit, a first switch device and a second switch device, and a selection unit. The rectification unit is connected to the resonant unit. The half-bridge output unit includes a first electric-controlled switch and a second electric-controlled switch in series. The first and second switch devices are connected to the first and second electric-controlled switches. The selection unit may turn on the first switch device and the second electric-controlled switch when a potential is rising that turns on the discharging lamp and turn off the second switch device and keep turning on the second switch device when the discharging lamp is lighting. The selection unit further turns on the second switch device to turn off the second electric-controlled switch for turning off the discharging lamp in a low power condition.
