Abstract:
Provided is a light emitting device improved in safety to an eye. The light emitting device includes: a semiconductor laser element for emitting laser light; an optical conversion member for converting coherent laser light which is emitted from the semiconductor laser element into incoherent light, and for emitting the incoherent light; and a safety device for preventing the coherent laser light from exiting to an outside.
