Light transmission assembly

A light transmission module, comprising:

• a base defining opposite first and second faces and opposite third and forth faces connecting with the first and second faces;
• a first light port portion integrally projecting from the first face of the base, the first light port portion being in step shape and having first coupling faces and end faces perpendicular to the first coupling face;
• lenses integrally projecting outwards at the third face of the base;
• wherein the base defines a slant reflex face, and the lenses and the first light port portion are aligned with the slant reflex face in different directions.

A light transmission assembly comprising:

• a waveguide module defining a plurality of light paths terminated at a roughly obliquely arranged first light port portion;
• a light transmission module defining a roughly obliquely arranged second light port portion complementarily coupled to said first light port portion and essentially aligned with each other in an extension manner along a first direction;
• a slanting reflection face formed on the light transmission module spaced from and opposite to an interface of said coupled first and second light port portions in said first direction so as to receive light coming therefrom;
• and
• a plurality of lens-like structure formed on the light transmission module and opposite to said slanting reflection face in a second direction perpendicular to said first direction;
• wherein
• the light coming from the coupled first and second light port portions hits the slanting reflection face in the first direction, and is subsequently deflected toward the lens-like structure in said second direction.
