The present invention provides an illumination control circuit of a dimming light emitting diode (Light Emitting Diode, LED) is used. This control circuit includes a voltage divider, and a controller adapted bleeder. The voltage divider from the input terminal receiving an input voltage to generate a dimming signal. The controller is based on the dimming signal to generate a switching signal, wherein the controller further generates a control signal based on the input voltage. Bleeder be adapted to receive the control signal and a control signal based on the discharge current drawn from the input terminal.
