A low power consumption bleeder circuit is disclosed, and it is coupled to an alternating-current (AC) power source, an input filtering capacitor, and a rectifying filter. The low power consumption bleeder circuit includes a first switch component, a second switch component, and a controller. The first switch component is coupled to a first input terminal of the AC power source and a first connection terminal of the rectifying filter. The second switch component is coupled to a second input terminal of the AC power source and the first connection terminal of the rectifying filter. When the AC power source is detected to be removed, the controller controls at least one of the first switch component and the second switch component to be conductive.
