Light guide arrangement for a mobile communications device for optical data transmission, mobile communications device and method for optical data transmission

A mobile communications device for outputting at least one of images or sound to a user, the mobile communications device comprising:

• a light guide arrangement, comprising:
• a light guide body with a greatest extent in the principal light guiding direction;
• a first optical coupling member for coupling the optoelectronic interface component to the light guide body;
• a second optical coupling member with a first lens element that has a first optical axis transverse to the principal light guiding direction and with a first optical deflection element arranged along the first optical axis;
• and
• a third optical coupling member with a second lens element that has a second optical axis transverse to the principal light guiding direction and with a second optical deflection element arranged along the second optical axis;
• wherein the second optical axis differs from the first optical axis;
• wherein the communications device has an optical data interface that is coupled to the light guide body by the first optical coupling member.
