| 英文摘要 | A light source device (101) includes: a semiconductor light emitting device (1) which emits laser light; a wavelength conversion component (4) which emits fluorescence by being irradiated with the laser light emitted from the semiconductor light emitting device (1) as excitation light; and a photodetector (7) on which a portion of light emitted from the wavelength conversion component (4) is incident. The photodetector (7) is disposed at a location off a light path of usable radiation light which is emitted from the wavelength conversion component (4) to a space and used as illumination light. |
