Original Abstract Submitted
a first wavelength converting member contains a first wavelength-converting element which produces first spontaneous emissions of light having multiple wavelengths longer than a wavelength of first excitation light. a second wavelength converting member contains a second wavelength-converting element which produces second spontaneous emissions of light having multiple wavelengths longer than a wavelength of a second excitation light. an optical member is interposed between the second wavelength converting member and the first wavelength converting member. a motor rotates the optical member. in the optical member, a plurality of filter portions are arranged along a circumference of a circle centered around a center axis of rotation of the optical member. each of the multiple wavelength ranges includes a wavelength of at least one of the second spontaneous emissions of light having the multiple wavelengths produced by the second wavelength converting member. the wavelength is at least one of the multiple wavelengths.
