<P>PROBLEM TO BE SOLVED: To provide a technique for enhancing controllability of light emitting elements, in a light source device using a plurality of light emitting elements. <P>SOLUTION: In this light source unit 1, components 11 are light emitting diodes (hereinafter called LEDs). Members 12 are reflectors each having a parabolic mirror. The parabolic mirror of the reflector 12 is formed into a shape of an upper paraboloid in cutting an all-round paraboloid by a plane horizontally crossing its axis (the one-side paraboloid cut by the plane crossing the axis is hereinafter called a half-paraboloid). Components 17 are control devices for controlling light emission of the LEDs 11. The control device 17 is arranged on a substrate 16 corresponding to each LED 11 to be set on the rear side with respect to the emission direction of the reflector 12. <P>COPYRIGHT: (C)2007,JPO&INPIT |
