Beschreibung
Zusammenfassung:	Provided is a fluorescent light source device which is provided with: a light-emitting element that radiates blue excitation light; a wavelength conversion element that is excited by the excitation light and radiates yellow fluorescence; a light collection optical system that collects the excitation light into the wavelength conversion element; and a first dichroic mirror that reflects or transmits the excitation light, and transmits or reflects the fluorescence, and which fluorescent light source device emits white light obtained by mixing the fluorescence from the wavelength conversion element and partial excitation light not converted by the wavelength conversion element, wherein even if the intensity of the excitation light fluctuates, the color temperature of the white light to be emitted can be kept constant. The fluorescence light source device is characterized by being further provided with an auxiliary light source that radiates light in the same blue region as the excitationlight, and in that the li
