Patent ID: 8829803

Claim:
A power supply system comprising: an illumination circuit adapted to receive an AC voltage; the illumination circuit comprising a first switch unit and at least one light emitting unit; and a control circuit adapted to receive a DC voltage; the control circuit comprising a first winding unit, a second switch unit, and a second winding unit; wherein the second winding unit is adapted to provide the DC voltage to the first winding unit by the second switch unit; the first winding unit is adapted to provide the AC voltage to the at least one light emitting unit by the first switch unit; and the at least one light emitting unit is adapted to emit light when receives the AC voltage; wherein the control circuit further comprises a first switch and a second switch; a first terminal of the first winding unit is electrically connected to receive the DC voltage via the second switch unit and the first switch electrically connected in series; a second terminal of the first winding unit is grounded; a first terminal of the second winding unit is electrically connected to receive the DC voltage via the second switch; and a second terminal of the second winding unit is grounded.
