    摘要: A light source device includes a first light source configured to emit light within a first wavelength band, a light-source light production section configured to sequentially produce light-source light of a plurality of colors at predetermined frequency by using light emitted by the first light source, a second light source configured to emit light within a second wavelength band different from the first wavelength band, and a light source control section configured to control drive timing for each of the first and second light sources such that a light emission period for light-source light using light emitted by the second light source is positioned between light emission periods for the light-source light of the plurality of colors produced by the light-source light production section and that the light-source light using light emitted by the second light source has a frequency higher than that of the light-source light production section.

    摘要: A light source unit including an excitation light source for emitting light in a blue wavelength band, a fluorescent wheel, a light emitting device for emitting light in a red wavelength band and a light guiding optical system for guiding light emitted from the fluorescent wheel and the light emitting device to a light guiding device. The fluorescent wheel has a fluorescent area where a green fluorescent material layer for emitting fluorescent light in a green wavelength band is disposed and a diffuse area for converting light emitted from the excitation light source into diffuse light of which directivity is weak are disposed end to end in a circumferential direction. A concentration of weight content of the green fluorescent material and a thickness thereof are such that a luminescent intensity of fluorescent light emitted from the green fluorescent material layer is enhanced.
