Abstract: A light source device emits combined light, using a plurality of light sources. The light source device includes first, second and third light sources, and first and second combining members. The first light source emits light of a first wavelength band. The third light source uses the light of the first wavelength band as excitation light and emits light of a third wavelength band which is fluorescent light. The second light source emits light of a second wavelength band which is different from the third wavelength band. The first combining member combines the light of the first wavelength band and the light of the third wavelength band. The second combining member combines the combined light obtained by the first combining member and the light of the second wavelength band. The combined light obtained by the second combining member enters a light guiding unit.

Abstract: A light source device includes a light emitting element emitting light of a first wavelength band, a fluorescent wheel and a mirror. The fluorescent wheel includes a fluorescent area converting the light of the first wavelength band into fluorescent light and a reflection area reflecting the light of the first wavelength band. The minor reflects a component in a first polarization direction of the light of the first wavelength band and transmits a component in a second polarization direction orthogonal to the first polarization direction. The reflection area includes a reflecting surface and a polarization conversion layer including an optical axis and converts either the first or second polarization direction to another polarization direction. The optical axis of the polarization conversion layer is inclined by 45 degrees to a polarization direction of the light of the first wavelength band at an irradiation position thereof in the fluorescent wheel.
