Abstract
In an illumination device, an incidence angle of a laser beam, which is scanned by a laser beam scanning mechanism, with respect to a wavelength conversion member is set to an angle where the laser beam does not directly enter a projection lens when the wavelength conversion member is damaged, chipped or fallen off, and a laser light source and the laser beam scanning mechanism are located at a position corresponding to at least one of an upper side and a lower side of a light distribution pattern with respect to the wavelength conversion member, and are disposed to be deviated to either one of one side corresponding to a left side of the light distribution pattern and other side corresponding to a right side of the light distribution pattern.
