Abstract
A headlamp (1) that utilizes a laser beam includes a scattered-light emitting unit (21) that emits scattered light upon receipt of a laser beam deviated from a predetermined path through which the laser beam is to pass or a predetermined irradiation region that is to be irradiated by the laser beam.
Claims12
A laser-beam utilization device that utilizes a laser beam, the device comprising:
- a scattered-light emitting unit that emits scattered light upon receipt of a laser beam deviated from a predetermined path through which the laser beam is to pass or a predetermined irradiation region that is to be irradiated by the laser beam;
- a light source that emits the laser beam;
- and
- a light emitting unit that is disposed in the predetermined irradiation region and that emits fluorescence upon receipt of the laser beam emitted from the light source.
