<P>PROBLEM TO BE SOLVED: To realize prevention of destruction of a light source in case a light guide plate is structured of a plurality of light guide bodies. <P>SOLUTION: The light source module is provided with a light guide plate 20 structured of a plurality of light guide bodies 21 arrayed in parallel, LED light sources 12 having light sources arranged at both ends in a length direction of the light guide bodies 21, and a light-path conversion structure for changing a light path of beams incident from at least one of the ends in the length direction of the light guide bodies 21 to a light extraction side. A through-hole 23 for positioning the LED light sources 12 and the light guide bodies 21 is formed at one of the end parts in the length direction of the light guide bodies 21. Further, a distance D2 between the end part opposite to the through-hole 23 in the light guide bodies 21 and the LED light sources 12 is to be larger than that D1 between the end part at the side of the through-hole 23 in the light guide bodies 21 and the LED light sources 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
