Abstract
A lamp and an illumination system and a driving method thereof are provided. The lamp includes a lighting unit, a conversion unit, and a driver. The conversion unit is capable of receiving an input pulse width modulation (PWM) signal and converting the input PWM signal into an output PWM signal, wherein a frequency of the input PWM signal and a frequency of the output PWM signal are different. The driver is coupled between the lighting unit and the conversion unit. The driver is capable of receiving the output PWM signal and generating a driving signal to drive the lighting unit according to the output PWM signal.
