<P>PROBLEM TO BE SOLVED: To provide a light source device of which brightness unevenness is hard to occur, improvement of incident efficiency is prospected, and reduction of workability in manufacturing is less. <P>SOLUTION: This light source device 100 includes: a light-emitting module 110 having a long substrate 111 and a plurality of semiconductor light-emitting elements 112 mounted on the upper face 111a of the substrate 111; a heat sink 120 arranged on the lower face 111c side of the substrate 111 along the longitudinal direction of the substrate 111; and a reflector 130 which is mounted on both side faces of the heat sink 120 in a state that both end portions of the short-length direction of the substrate 111 is embraced and that is pressed to the heat sink 120 and in which light emitted from the semiconductor light-emitting element 112 by a pair of opposing reflection faces 131d sandwiching the semiconductor light-emitting element 112 is condensed on the upper side of the perpendicular direction against the upper face 111a of the substrate 111. <P>COPYRIGHT: (C)2011,JPO&INPIT |
