<P>PROBLEM TO BE SOLVED: To provide a light source device that can suppress deterioration and burning damage of a fluorescent layer and prolonging lifetime and moreover suppress degradation of light utilization efficiency, and can perform downsizing and weight reduction of the light source device as well. <P>SOLUTION: The light source device 10 includes a plurality of solid light sources 24, a plurality of collimator lenses 32, a reflection part 40, a condensing optical system 50, and a fluorescent layer 64 generating fluorescence from at least a part out of light from the condensing optical system 50. In an optical path between the plurality of the collimator lenses 32 and the fluorescent layer 64, there is provided at least one anamorphic face, and the plurality of the solid light source 24 are arranged at a position in an optical axis direction different from a focal position of the plurality of collimator lenses 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
