Abstract:
A dimmer circuit may include: a rectification module, a control module and an output module, wherein the control module receives an input signal rectified through the rectification module and controls the output module to supply a load with an output signal in accordance with the input signal, and a compensation module which collects sampled signals characterizing dimming state of the dimmer circuit between the control module and the output module, and supplies the control module with a compensation signal in accordance with the sampled signals, the control module changing the value of the output signal according to the input signal and the compensation signal.
