Abstract
An embodiment of the invention discloses a control circuit, comprising a dimming control unit, a current ring control unit, an auxiliary power supply unit, an output unit, an isolating unit and a switch unit. The auxiliary power supply unit is connected with the current ring control unit; the current ring control unit is connected with the output unit; the isolating unit is connected with the dimming control unit and the current ring control unit; the switch unit is connected with the dimming control unit and the auxiliary power supply unit. The isolating unit and the switch unit are arranged in the control circuit, the dimming control unit and the output unit can be electrically isolated, and operation safety is greatly ensured for a user. In addition, when an output signal of the dimming control unit is too large, the switch unit cuts of power from the auxiliary power supply unit to the current ring control unit, and the output unit also stops operating; power consumption of the output unit is greatly reduced.
