Light source system

A light source system comprising:

• a first solid-state light source configured to emit first excitation light;
• a first wavelength converting member implemented as an optical fiber containing a first wavelength-converting element, the first wavelength-converting element being excited by the first excitation light to produce first spontaneous emissions of light having multiple wavelengths longer than a wavelength of the first excitation light, the first wavelength-converting element being excitable by a first amplified spontaneous emission of light;
• a second solid-state light source configured to emit second excitation light;
• a second wavelength converting member containing a second wavelength-converting element, the second wavelength-converting element being excited by the second excitation light to produce second spontaneous emissions of light having multiple wavelengths longer than a wavelength of the second excitation light, the second wavelength-converting element being excitable by a second amplified spontaneous emission of light;
• an optical member interposed between the second wavelength converting member and the first wavelength converting member and including a plurality of filter portions provided for light rays falling within multiple wavelength ranges, respectively;
• a motor configured to rotate the optical member;
• and
• a control unit configured to control the motor and the second solid-state light source,
• the optical member having the plurality of filter portions arranged side by side along a circumference of a circle, the circle being centered around a center axis of rotation of the optical member, and
• each of the multiple wavelength ranges including a wavelength of at least one of the second spontaneous emissions of light having the multiple wavelengths which have been produced by the second wavelength converting member, the wavelength being at least one of the multiple wavelengths.
