- the grid mat produced by injection molding consists of longitudinal and transverse bars crossing in a single plane, between which apertures exist are, wherein the Lichtleitite are molded at the intersections of the lattice mat thus prepared and whose longitudinal extent extends perpendicular to the plane of the grid mat.
- the grid mat also consists of in a plane intersecting longitudinal and transverse bars, but the Lichtleitchane are not molded in the intersection of the longitudinal and transverse bars, but in the openings between the intersecting longitudinal and crossbars.
- a two-stage injection molding process takes place in which first a grid body or a support mat is produced in a first step and in a second step, the light guide pins at selected points (either at the intersections of a grid mat or the openings of a - preferably not designed as a latticework - support mat or a lattice train forming grid mat) the Lichtleitchane be molded.
- the light guide of a light-conducting building material is designed as a self-supporting 2D or 3D grid body of bars with thickness / diameter greater than or equal to 1 mm, the self-supporting 2D or 3D Grid body about the same or only slightly smaller width B, or length L, or floor plan dimensions B x L or overall external dimensions B x L x H has, as the mold itself, in which the light-conducting member was made. Accordingly, a molded article with embedded Lichtleitchanen is proposed.
- the molded body can be designed as a facade panel, masonry stone or as a êtausbauplatte.
- the support mat is poured with the formed thereon Lichtleitchanen with a curing potting compound. In this case, only one base layer is present. However, if an internal insulation (one-sided or two-sided) applied to the support mat during manufacture, then this insulation is referred to as a facing layer.
