Abstract:
1. A photoelectric conversion device comprising: a circuit board; a plurality of light-emitting modules arranged on the circuit board in a first straight line and spaced apart from each other; a plurality of light-receiving modules arranged on the circuit board in a second straight line and spaced apart from each other; and an optical coupling module comprising a first optical surface, a second optical surface perpendicular to the first optical surface, a reflecting surface obliquely relative to the first optical surface and the second optical surface, a plurality of first converging lenses arranged on the first optical surface in a third straight line, a plurality of second converging lenses arranged on the first optical surface in a fourth straight line, a plurality of third converging lenses arranged on the second optical surface in a fifth straight line, and a plurality of fourth converging lenses arranged on the second optical surface in a sixth straight line, the first straight line, the second straight line, the third straight line, the fourth straight line, the fifth straight line, and the sixth straight line being substantially parallel to each other, the first converging lenses aligned with the light-emitting modules and corresponding to the third converging lenses, the second converging lenses aligned with the light-receiving modules and corresponding to the fourth converging lenses, the reflecting surface configured for reflecting light beams from the first converging lenses toward the corresponding third converging lenses and for reflecting light beams from the fourth converging lenses toward the second converging lenses.
