LIGHT EMITTING DEVICE

Provide a light-emitting device capable of condensing laser light rays output from a plurality of light sources to be a spot whose diameter is less than or equal to a predetermined size to increase a light intensity per unit area. A light-emitting device includes a light source unit including a plurality of laser light sources; a dioptric system that refracts each light ray input from each of the plurality of laser light sources; a condensing optical system that condenses a plurality of refracted light rays input from the dioptric system, respectively, wherein the dioptric system is configured to refract a plurality of center light beams that are output along optical axes of the plurality of laser light sources, respectively, to proceed in directions each departing from an optical axis of the condensing optical system as proceeding toward the condensing optical system.
