A light source device having a wavelength converting unit having a first wavelength converting member for absorbing a first excitation light having a first wavelength range, and emitting a first wavelength-converted light; and a second wavelength converting member for absorbing a second excitation light having a second wavelength range, and emitting a second wavelength-converted light, wherein the wavelength converting unit emits a first emission light having a first spectral shape when irradiated with the first excitation light, and emits a second emission light having a second spectral shape when irradiated with the second excitation light, and wherein at least a portion of the first wavelength converting member and at least a portion of the second wavelength converting members are arranged within an irradiation space that is commonly irradiated by both the first excitation light and the second excitation light. |
