  • Patent number: 10332866
    Abstract: There is provided a light source device which includes at least one kind of light emitting elements of which the number is one or more, and a phosphor excited by output light of the light emitting element. In a case where all light emitting elements mounted before the phosphor is mounted in the light source device emit light, the light source device has a peak wavelength of output light in a first wavelength region of longer than 440 nm and 490 nm or shorter, and has a peak wavelength of output light in a second wavelength region of 380 nm to 440 nm. Thus, it is possible to provide a light source device which can cause the white color, the dark-blue color, and the black color to simultaneously look vivid when an irradiation target (for example, clothes or the like) is irradiated.
