Abstract

In a projection device and a light source system thereof, the light source system includes a light source module, a driver, and a control circuit. The light source module includes light sources to provide beams with different wavelength ranges. According to a selection signal, the control circuit selects one of a first pulse width modulation signal, a second pulse width modulation signal, and a third pulse width modulation signal as a pulse width modulation signal to output to the driver. The driver drives the light source corresponding to the selection signal with the pulse width modulation signal provided by the control circuit.
