PROBLEM TO BE SOLVED: To provide a light source system capable of performing a stable light-emitting operation independently of a set value of color temperature. SOLUTION: In accordance with a color temperature of a light source part 10 set by a light quantity balance control part 121, connection switching between a plurality of resistors connected in parallel with each other (for examples, resistors R1 and R2) in resistor parts 114R, 114G, and 114B is controlled by control signals D6R, D6G, and D6B supplied from the light quantity balance control part 121. Thus, a resistance value is adjusted as the whole of resistor parts 114R, 114G, and 114B in accordance with the color temperature, and operation points in a PWN driver 113 and the resistor part 104B can be maintained.
