Claim:
1. A light source device, comprising: a first light source configured to emit first light having a first wavelength range; a wavelength convertor, disposed on an optical path of the first light emitted from the first light source, configured to receive the first light having the first wavelength range from the first light source to emit light having other wavelength range different from the first wavelength range of the first light; a cyclical movement unit configured to cyclically move the wavelength convertor while crossing the optical path of the first light emitted from the first light source, and optical parts configured to define an optical path of the first light emitted from the first light source, and an optical path of the light emitted from the wavelength convertor; a detector configured to detect a cyclic movement condition of the cyclical movement unit; a received light quantity reducing unit configured to reduce light quantity of the first light received by the wavelength convertor when a cyclic movement condition detected by the detector satisfies a specified abnormal condition while outputting the first light emitted from the first light source having the first wavelength range or the light having other wavelength range emitted from the wavelength convertor to outside the light source device; and a drive unit configured to drive rotation of the rotatable member; and wherein
