发明名称 LIGHT SOURCE DEVICE AND PROJECTOR
摘要 <P>PROBLEM TO BE SOLVED: To provide a light source device and a projector that can realize an electrical function for time division of colors, compensate for fluctuations among individual units of equipment, and adjust the color balance during hardware operation. <P>SOLUTION: A light source device comprises a first light source that radiates excitation light of a prescribed wavelength band, light path switch-over means that switches over the light radiated from the first light source into a first light ray radiated in a first direction and a second light ray radiated in a second direction on a time division basis, a light emitting board on which a fluorescent material layer that emits fluorescent light having a wavelength band differing from the excitation light in response to the second light ray, and a light guiding optical system that guides the first light ray and the fluorescent light to the same optical path. <P>COPYRIGHT: (C)2012,JPO&INPIT
