Abstract:
1. A light source unit comprising: an excitation light shining device for emitting excitation light; a luminescent plate having a luminescent light emitting area on a base material and adapted to emit a luminescent light ray of a predetermined wavelength band by the excitation light being shone onto the luminescent light emitting area from the excitation shining device; two types of light source devices for emitting light rays of wavelength bands which are different from the wavelength band of the luminescent light ray emitted from the luminescent plate; a light guiding optical system for guiding individually the luminescent light ray emitted from the luminescent plate and the light rays emitted from the two types of light sources to a predetermined plane; and a light source control device for controlling individually the emission of light from the excitation light shining device and the two types of light source devices; wherein:
