Abstract

A light transmission device, and particularly a fiber optical light transmission system for transmitting energy, has a light conducting fiber bundle formed by a plurality of light conducting fibers, and with at least one coupling element for coupling or decoupling a bundle of light rays focused on the bundle of light conducting fibers. In order to avoid energy overloading of the individual light conducting fibers, and to increase the efficiency of the energy transmission, each coupling element has a coupler array having a plurality of light focusing cells. The coupler array of light focusing cells will focus an incident bundle of light rays multiple times on the light conducting cross section of each of the light conducting fibers of the light conducting fiber bundle.

Dependent claims

A fiber optical light transmission device for transmitting energy, comprising

a bundle of light conducting fibers formed by a plurality of light conducting fibers, each fiber having a light conducting cross section area;
a coupling element positioned adjacent to said bundle of fibers for transmitting an incoming incident bundle of light rays;
said coupling element having two coupler arrays, and each coupler array having a plurality of light focusing cells, and each coupler array focusing said incoming incident bundle of light rays multiple times using said plurality of light focusing cells;
each coupler array comprising a cylindrical lens array such that said two coupler arrays form two crossed cylindrical lens arrays;
and
each light focusing cell of said plurality of light focusing cells focusing said light rays on said light conducting cross section area within each corresponding light conducting fiber for a light conducting fiber bundle.
