Abstract: A light source device includes a primary light source that emits primary light, a light guide that guides the primary light, an optical conversion unit that converts the primary light emitted from the light guide and having a first light distribution angle into secondary light having a second light distribution angle and emits the secondary light, and a light distribution adjustment unit that adjusts the secondary light to illumination light having a third light distribution angle and emits the illumination light. The light distribution adjustment unit and the optical conversion unit slide each other. The light distribution adjustment unit allows a light distribution adjustment amount for adjusting the second light distribution angle of the secondary light to adjust to the third light distribution angle of the illumination light.

Abstract: A light source device includes a first excitation light source which emits first excitation light having a wavelength in a first wavelength region, a first optical member, a second optical member and a holding member which holds the first optical member and the second optical member. The first optical member converts at least part of the first excitation light to emit first wavelength converted light, and increase divergence angle of the transmitted first excitation light by a first incremental angle. A second optical member is disposed in a region including an optical axis of the first excitation light, and increases the divergence angle of the transmitted first excitation light by a second incremental angle larger than the first incremental angle.
