Control circuit and control method for dimming LED lighting circuit
The present invention provides a control circuit for dimming LED lighting. The control circuit comprises a voltage divider, a controller and an adaptive bleeder. The voltage divider receives an input voltage from an input terminal to generate a dimming signal. The controller generates a switching signal in response to the dimming signal. The controller further generates a control signal in response to the input voltage. The adaptive bleeder receives the control signal and draws a bleeder current from the input terminal in response to the control signal.
