发明名称 LIGHT SOURCE UNIT AND PROJECTOR
摘要 To provide a light source unit enabling a stable projection without a luminescent material heating and a projector, a projector of the invention including a light source unit, a display device, a light guiding optical system, a projection side optical system and a light source control device. The light source unit includes an excitation light shining device, a luminescent wheel emitting a luminescent ray of a green wavelength band and a light source optical system collecting rays from the luminescent wheel and respective light sources on a predetermined plane. The light source control device controls the excitation light shining device, each light source device of red and blue so that a period of time required for turning-on once of the excitation light shining device, and each light source device of red and blue becomes a non-integral multiple of a period of time required for one rotation of the luminescent wheel.
