A light source system includes a light unit, a control unit, a light detector and a determining unit. In this case, the control unit is used to drive the light unit. The light detector is for detecting the brightness of the light unit, and generates a brightness detection signal based on the brightness of the light unit. The determining unit receives the brightness detection signal so as to determine whether the brightness of the light unit is equal to a predetermined value or not. When the brightness of the light unit is not equal to the predetermined value, the determining device then outputs a control signal to the control unit. The control unit generates an adjustment signal based on the control signal so as to adjust the brightness of the light unit.
