Abstract:
1. A light source unit comprising: a light emitting plate which has a plurality of segment areas and in which a luminescent material layer which emits light having a predetermined wavelength band by receiving excitation light and a transmissive portion which transmits light are formed respectively on at least the plurality of segment areas; a primary light source for emitting the excitation light onto the luminescent material layer; a secondary light source for emitting light having a wavelength band which differs from wavelength bands of the luminescent light emitted from the luminescent material layer and the excitation light emitted from the primary light source; a light guiding optical system for guiding light emitted from the light emitting plate and the light emitted from the secondary light source to a same optical path; and a light source controller for controlling emission of light from the primary light source and the secondary light source; wherein:
