Abstract
Method of producing light-conducting LED bodies of a free-flowing material by introduction into a mold. Here, the volumetric flow of a free-flowing material, at a distance of the electrode plane from the charging point that is greater than 35% of the distance between the charging point and the mold side of the mold situated opposite the charging point—above the charging point and below the chip plane on the mold side of the charging point, is choked by at least one cross-sectional constriction, while—at a distance that is smaller than or equal to 35% of this distance—choking takes place on the mold side situated opposite the charging point. The present invention develops a method of producing light-conducting LED bodies in which, at customary output capacities of the molding operation, the LED electronics are not damaged.
