1. A semiconductor light emitting device comprising:

  • a semiconductor light emitting element that emits first wavelength light;

    a first fluorescent material that absorbs the first wavelength light and emits second wavelength light having a longer wavelength than the first wavelength light; and

    a second fluorescent material that absorbs the first wavelength light and emits third wavelength light having a longer wavelength than the second wavelength light, the first fluorescent material and the second fluorescent material being represented by a common chemical composition formula, and the first wavelength light, the second wavelength light, and the third wavelength light being combined into light emission of mixed color.
