Abstract
A driving device of a lighting system includes a rectifier circuit, a voltage reducing circuit, a dimmer circuit, and a driver module. The rectifier circuit outputs a pulsating direct current voltage. The voltage reducing circuit is operable to output a reduced direct current voltage associated with the pulsating direct current voltage. The dimmer circuit generates a dimmer signal based on detected occurrence of an interruption to the pulsating direct current voltage. Based on the dimmer signal, the driver module generates a pulse width modulated signal for driving a lighting appliance to generate light with an intensity corresponding to the dimmer signal.
