发明名称 LIGHT SOURCE UNIT AND PROJECTOR
摘要 In a projector which includes a light source unit 63, a light smoothing unit, a display device, a projection side optical system and a projector control unit, the light source unit 63 includes a light generating device for generating light of a specified wavelength band which includes a first light source 152 which is a light emitting diode or solid-state light emitting device for emitting light of a predetermined wavelength band, a second light source 153 which is a light emitting diode or a solid-state light emitting device for emitting excitation light, and a third light source 154 for emitting light of the same wavelength band as that of the first light source 152 using the light emitted from the second light source 153 as excitation energy, and the third light source 154 is formed by a phosphor which transmits light from the first light source 152 and absorbs light emitted from the second light source 153.
