<p>The invention relates to a method for manufacturing light panels, consisting of a plate- or sheet-shaped carrier (7) with light conducting fibres (2) fixed therein according to a given pattern, wherein the ends of fibres (2) taken from a fibre supply (6) are inserted through openings (3) in the bottom of a mould (1), and wherein the mould (1) is filled with a layer of a castable or spoutable and quickly setting material for forming the carrier (7). Subsequently the carrier (7) is released and removed from the mould (1) after having set in such a manner the fibres (2) are retained therein. Before or after removing, the fibres (2) are cut off at the required length, the fibres (2) coming from the supply (6) being pulled through the openings (3) during removal of the carrier. Furthermore a method for manufacturing a casting mould (1) is described, which mould consists of the same material as the object (17) to be formed therein, and the mould (1) thus obtained is provided with a coating (28) not adhering to said material and being fixed to said mould (1) by means of an adhesive layer (26).</p> |
