LIGHT SOURCE UNIT AND PROJECTOR |
摘要 |
A light source unit is provided which includes: a first light source which shines excitation light of a predetermined wavelength band; an optical path switching device which switches in a time-sharing fashion the light shone from the first light source into first light which is shone in a first direction and second light which is shone in a second direction; a light emitting plate on which a luminescent material layer is formed which emits luminescent light of a wavelength band which is different from that of the excitation light when receiving the second light; and a light guiding optical system which guides the first light and the luminescent light to the same optical path. |
