Abstract
The method for manufacturing optical light guide elements comprises providing a plurality of initial bars, each initial bar extending along a respective initial-bar direction from a first bar end to a second bar end and having a first side face extending from the first bar end to the second bar end, the first side face being reflective; positioning the initial bars in a row with their respective initial-bar directions aligned parallel to each other and with their respective first surfaces facing towards a neighboring one of the initial bars; and fixing the plurality of initial bars with respect to each other in the position to obtain a bar arrangement.
