Abstract:
1. A photoelectric conversion device comprising: a circuit board; a plurality of light-emitting modules mounted on the circuit board; a plurality of light-receiving modules mounted on the circuit board and being apart from the light-emitting modules; and an optical coupling module mounted on the circuit board and comprising a first optical surface, a second optical surface perpendicular to the first optical surface, a reflection surface oblique relative to the first optical surface and the second optical surface, a plurality of first converging lenses formed in the first optical surface, and a plurality of second converging lenses formed on the second optical surface corresponding to the first converging lenses, the first converging lenses aligned with the light-emitting modules and the light-receiving modules, the reflection surface configured to reflect parallel light beams from the first converging lenses toward the second converging lenses and to reflect parallel light beams from the second converging lenses toward the first converging lenses; and a protecting member mounted on the circuit board, the protecting member shielding the optical coupling module, the light-emitting modules, and the light-receiving modules, and the second converging lenses exposed outside the protecting member.
