Abstract
A dimming module includes a triggering circuit, a control signal generating circuit, a voltage converting circuit, and a linear driving circuit. The triggering circuit is configured to control a trigger delay angle of an AC input voltage according to a dimming command, in order to output a first voltage signal correspondingly. The control signal generating circuit is configured to output a control voltage according to the first voltage signal. The voltage converting circuit is configured to output a DC operating voltage having an operating level according to the first voltage signal, and output the DC operating voltage to a lighting module, in which the lighting module includes a light-emitting diode. The linear driving circuit is configured to drive the lighting module according to the control voltage.
