<P>PROBLEM TO BE SOLVED: To provide an optical module where a width (area) of convergent light at one focus can be reduced and the position of the focus can be easily recognized. <P>SOLUTION: The optical module includes a plurality of light sources 1 disposed so that their optical axes cross each other at one point, and an optical lens 2 which has, as a focus F0, the one point at which the optical axes of the plurality of light sources 1 cross each other. The optical lens 2 includes, correspondingly to each of the light sources 1, a total reflection surface 5, a first light incident surface 3 for refracting light from the corresponding light source 1 toward the focus F0, and a second light incident surface 4 for refracting light from the corresponding light source 1 toward the total reflection surface 5. The total reflection surface 5 totally reflects light from the second light incident surface 4 toward the focus F0, and the focus F0 is located in the optical lens 2 relative to a light emission surface 6 of the optical lens 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
