Abstract
A control circuit and method for a bleeder, a chip, and a driver system. The bleeder control circuit is connected to a dimmer detector used for detecting the presence or absence of a dimmer and a type of the dimmer. The control circuit of the bleeder is used to receive a detection signal outputted by the dimmer detector, and generate a control signal for the bleeder according to the detection signal, the control signal is used to control an operating state of the bleeder. The application correspondingly generates a control signal for a bleeder according to a detection signal indicating the presence or absence of a dimmer and the type of the dimmer so as to control the bleeder to operate only at a given phase interval, and may thereby reduce the power consumption of the bleeder when ensuring the stable operation of a dimmer.
