Abstract:
An illumination device includes: an excitation light source that emits excitation light having a first wavelength; a fluorescent substance that, when irradiated with the excitation light, emits light having a second wavelength longer than the first wavelength and transmits a part of the excitation light, and thereby multiplexes and emits the transmitted excitation light having the first wavelength and the emitted excitation light having the second wavelength; and a driving unit that moves an irradiation position of the excitation light in the fluorescent substance with the passage of time.

Claim (Index 23):
An image display apparatus, comprising:\n a light source device including: an excitation light source configured to emit excitation light having a spectrum with a peak wavelength within a first wavelength range; a wheel unit including:\n a fluorescent substance, responsive to being irradiated with the excitation light, configured to emit emission light having a spectrum with a peak wavelength within a second wavelength range which is different from the first wavelength range, and \n a reflector configured to reflect the emission light emitted from the fluorescent substance, and \n a reflection prevention substance provided at an incidence side of the excitation light of the fluorescent substance; and \n an optical condenser configured to condense the excitation light emitted from the excitation light source, wherein the excitation light is incident at an angle of less than 20 degrees or less for the wheel unit; a light modulator configured to modulate light emitted from the light source device into image light; and a projection optical system configured to project the modulated image light.
