The light source module has a first light source, a wavelength transforming unit, and a driver. The first light source generates a first light beam having a first wavelength according to a first pulse width modulation (PWM) signal. The wavelength transforming unit transforms the first light beam into a second light beam having a second wavelength. The driver drives the wavelength transforming unit, such that the first light beam irradiates a start position on the wavelength transforming unit when a rising edge of the first PWM signal is detected. The start position is determined by a controller.
