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.
Claims15
An illumination device comprising:
- a light source which emits light of a specific wavelength;
- a fluorescent member which comprises a fluorescent substance and is irradiated with light emitted from the light source;
- a reflected light sensing part which detects the specific wavelength among light reflected from the fluorescent member;
- and
- a light source control part which controls light emitted from the light source based on a detection signal of the reflected light sensing part.
A vehicle comprising:
