Abstract: A light source unit includes an optical wheel having a plurality of segment areas, the segment areas including at least two luminescent material layers having different characteristics and a transmission portion provided in a circumferential direction. The light source unit further includes a rotation driving unit for driving to rotate the optical wheel, an excitation light source for shining light onto the optical wheel, a light emitting element, and a light guiding optical system for collecting a light beam from the optical wheel and a light beam from the light emitting element to a same optical path. The excitation light source is selectively turned on to illuminate the transmission portion or the at least two luminescent material layers, and the light emitting light source is turned on for a period of time during which the excitation light source does not shine the excitation light.
