发明名称 Light source unit that includes a luminescent material layer, a primary light source that emits light to excite the luminescent material layer, and an optical system including a plurality of mirrors, and projector
摘要 A light source unit and a projector including the light source unit are provided. The light source unit includes a luminous wheel having a segment area on which a luminescent material layer is formed which emits light of a predetermined wavelength band by receiving light, and a segment area which is made into a transmission portion which transmits light, a primary light source which shines light of a visible wavelength band onto the luminous wheel, a secondary light source which emits light of a wavelength band which is different from light from the luminescent material layer and light from the primary light source, a collective optical system which collects light from the luminous wheel and the secondary light source to cause them to converge to a same optical path, and a light source control device which controls the emission of light from the light sources.
