<P>PROBLEM TO BE SOLVED: To emit light from a plurality of semiconductor light emitting elements compactly, and obtain highly bright emission light even when the whole of a light source apparatus is small sized. <P>SOLUTION: The light source apparatus 1 is provided with a stacked semiconductor light emitting element, to which electric power is supplied from a pair of electrodes by stacking and connecting in the direction of the surface 3 a plurality of semiconductor light emitting elements 2a, 2b having the electrodes on the surface 3 and the rear surface 4 on and to the bottom 14 of a case 13 having an opening 20 that forms an exit port. The stacked semiconductor light emitting element is used as one light source. A slope 15 for reflecting radiated light from the side of a side surface 6 in the direction of the opening 20 is provided in a case 13 such that the placement face of the stacked semiconductor light emitting element and the opening 20 are connected. Consequently, light from the stacked semiconductor light emitting element excepting the direction of the opening 20 is effectively reflected and is guided in the direction of the opening 20. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
