    Abstract: The method for manufacturing optical light guide elements comprises a) 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; b) 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; c) fixing the plurality of initial bars with respect to each other in the position achieved in step b) to obtain a bar arrangement. The method further comprises at least one of the following steps d), d′), d″): d) segmenting the bar arrangement into bars referred to as prism bars each of which comprises a portion of at least two different ones of the plurality of initial bars, by conducting a plurality of cuts through the bar arrangement; in particular wherein the cuts are parallel cuts; d′) segmenting the bar arrangement into bars referred to as prism bars by separating the bar arrangement into parts along cut lines, wherein the cut lines are at an angle with the initial-bar directions; d″) segmenting the bar arrangement into bars referred to as prism bars by separating the bar arrangement into sections by creating cut faces which are at an angle with respect to the initial-bar directions. And the method further comprises e) segmenting the prism bars into parts.

    Abstract translation: 用于制造光学光导元件的方法包括：a）提供多个初始棒，每个初始棒沿着相应的初始棒方向从第一棒端部延伸到第二棒端部，并且具有从第一棒延伸的第一侧面 结束于所述第二杆端部，所述第一侧面是反射性的; b）将初始条定位成一行，使它们各自的初始条方向彼此平行排列，并且使它们各自的第一表面面向相邻的一个初始条; c）将多个初始杆相对于彼此固定在步骤b）中获得的位置以获得杆布置。 该方法进一步包括以下步骤d），d'），d“'中的至少一个：d）将所述条配置分割成称为棱柱条的条，所述棱条中的每一个包括至少两个不同的 通过在所述杆装置中进行多次切割，从而形成多个初始杆; 特别是其中切口是平行切口; d'）通过沿着切割线将条配置分成多个部分来将条配置分割成称为棱柱条的条，其中切割线与初始条方向成角度; d“）通过产生与初始棒方向成一定角度的切割面，将棒排列分成多个部分，将棒排列分割成称为棱柱棒的棒。 并且该方法还包括e）将棱镜条分割成多个部分。
