Abstract: A light source device includes a plurality of light sources; a condensing optical member; a fluorescent unit that converts at least a portion of the light from the light sources and condensed by the optical member into light including converted light and light from the light sources; and a sensor that detects an anomaly in the fluorescent unit, such sensor disposed within a circular area circumscribed by the light sources.

Abstract: A light-emitting device includes: a laser light source that radiates blue-based light as primary light; a wavelength converting member that emits secondary light, the secondary light including wavelength-converted light, the wavelength-converted light being the primary light converted into light having more long-wavelength components than the primary light; a first light-guiding member that transmits the secondary light emitted by the wavelength converting member; and a second light-guiding member which includes a resin material, and transmits the secondary light transmitted by the first light-guiding member, and the first light-guiding member and the second light-guiding member are connected by a connector, the connector including a numerical aperture (NA) converting member that optically connects a transmission path in the first light-guiding member and a transmission path in the second light-guiding member.
