<P>PROBLEM TO BE SOLVED: To provide a light source unit capable of attaining improvement in quality of light distribution, and to provide an illumination device using this light source unit. <P>SOLUTION: The light source unit is provided with a substrate 4 on which a plurality of light-emitting elements 10 are mounted and a reflector 6 which has a plurality of incident apertures 6i respectively opposed to the plurality of light-emitting elements 10, outgoing apertures 6o from which the light passing through the incident apertures 6i is emitted, and a plurality of reflecting surfaces 6f which widen from the incident apertures 6i toward the outgoing apertures 6o. Further, out of the reflecting surfaces 6f, the reflecting surfaces 6f which are located at the outermost part are provided so as to adjoin each other, and the reflecting surface 6fo which is a unit reflecting surface and formed at the outside has an angle established so that the reflecting light of the light emitted from the light-emitting element 10 may not go to the outside direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
