Light source device including laser-excited light source

A light source device comprising:

• at least one semiconductor laser for excitation;
• a laser-excited light source having a phosphor excited by the at least one semiconductor laser, and a first optical system for extracting fluorescence emitted from the phosphor;
• a plurality of light emitting diode (LED) light sources for emitting light having wavelengths different from a wavelength of the fluorescence;
• and
• a second optical system for synthesizing the fluorescence from the laser-excited light source with the light from the plurality of LED light sources, and emitting the synthesized light from a light emitting portion,
• the plurality of LED light sources including an LED light source configured to emit light in an ultraviolet range, and
• of the plurality of LED light sources, the LED light source configured to emit the light in the ultraviolet range being disposed at a position farther from the laser-excited light source than the remaining LED light source or LED light sources configured to emit light of other wavelengths.
