Abstract:
1. A light-emitting device, comprising: a plurality of laser beam sources each for emitting a laser beam; a fluorescent unit for emitting light in response to the laser beam emitted from at least one of the plurality of laser beam sources; an emission controller for controlling whether each of the plurality of laser beam sources emits light or not, at least a part of the plurality of laser beam sources being positioned in such a manner that irradiation regions of the fluorescent unit which are respectively irradiated with the laser beams emitted from the plurality of laser beam sources are positioned at least partially differently; and at least one optical element for controlling guide of the laser beams emitted from the plurality of laser beam sources toward the fluorescent unit, said at least one optical element being a mirror for controlling guide of the laser beams emitted from the plurality of laser beam sources by reflecting the laser beams emitted from the plurality of laser beam sources.
