Abstract: A dimming controller can operate in a first mode or a second mode to control dimming of a light-emitting diode (LED) light source. The dimming controller can include a voltage control terminal and a current control terminal. The voltage control terminal provides a pulse signal when the dimming controller operates in the first mode to operate a control switch in either a first state or a second state. A first current flowing through the LED light source increases when the control switch is in the first state and decreases when the control switch is in the second state. The voltage control terminal provides a control signal to the control switch to cut off the first current when the dimming controller operates in the second mode. The current control terminal conducts a second current through the LED light source when the dimming controller operates in the second mode.
