Abstract
An illumination device improved in safety to the eye is provided. The illumination device includes: a semiconductor laser element to serve as an excitation light source which emits laser light; a fluorescent plate which contains a fluorescent substance for emitting light of a desired color and is irradiated with laser light emitted from the semiconductor laser element; a light receiving element part which detects light reflected from the fluorescent plate; and a light source control part which controls laser light emitted from the semiconductor laser element based on a detection signal from the light receiving element part.
