Claim Text:
1. An illumination control system, comprising: a rectifying device, a damping device for inhibiting flickering, and a load circuit, wherein the illumination control system further comprises a recognizing control circuit connected between the rectifying device and the damping device, and wherein the recognizing control circuit comprises a recognizing signal output module and a switch module, the recognizing signal output module generates a first control signal indicating that a dimmer is not connected upstream the rectifying device or the dimmer is connected upstream the rectifying device and reaches a predetermined dimming level and a second control signal indicating that the dimmer is connected upstream the rectifying device and does not reach the predetermined dimming level and at least one damping resistor of the damping device is short connected or is connected by means of the switch module according to the first control signal or the second control signal, wherein the recognizing signal output module comprises a voltage sampling device configured to sample a voltage output from the rectifying device to output a sample voltage, a phase-cut angle detecting device configured to detect a phase-cut angle of the sample voltage to output a detection output signal, and an evaluating device configured to evaluate the detection output signal to generate the first control signal or the second control signal.
