Abstract: Disclosed is a method for producing light-guiding LED bodies in a mold, using a material that is flowable before becoming definitively solid. Each LED body comprises at least one light-emitting chip and at least two electrical connections that are connected to the chip. At least one flowable material is fed into the mold in chronologically separate steps via at least one of at least two locations. In a first step, the flowable material is fed into the mold so as to flow around the chip and the connections in that area. In further steps, one or several flowable materials are fed into areas other than the one in which the chip and connections are located. The inventive method for producing light-guiding LED bodies allows virtually all produced luminescent diodes to have the same optical characteristics and prevents the individual LED electronics from being spoiled through damage.

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.

Abstract: The invention relates to a method for producing light-guiding LED bodies, in two casting and/or injection molding steps, from a material which is free-flowing before being finally solidified. First, the electronic components, consisting of at least one light-emitting chip and at least two electrical terminals connected to said chip, are coated by means of casting or injection molding, and are then recoated by means of casting or injection moulding, at least in one region, in a larger LED end mold. The present invention provides a method for the production of light-guiding LED bodies, whereby almost all light-emitting diodes produced have the same optical characteristics, and rejection caused by damage of the individual LED electronic elements is avoided.

Abstract: The invention relates to a method for producing light-conducting LED bodies by injection molding into a mold of a material that is fusible prior to final solidification. Each LED body comprises at least one light-emitting chip and at least two wire-shaped electrodes that are electrically connected to the chip. The injection mold is evacuated via at least one opening per LED after positioning the electronic parts and closing. The evacuation opening is disposed in the proximity of the electrodes in the bottom area of the LED. The fusible material is injected between the bottom area and the chip or the reflector trough at least approximately parallel to the chip surface and at least approximately normal to a surface embodied by two electrodes, with the center line of the injection stream running between two electrodes. The inventive method for producing light-conducting LED bodies prevents the LED electronics from being damaged during normal performance of the injection molding process.

Abstract: The invention concerns a method for producing an optical waveguide from a material which is flowable before final solidification, in a mold, wherein, on a first introduction of the flowable material at least one radiation-emitting emitter with its connecting means electrically contacting the emitter is surrounded by said material, and one or more additional introductions of one or more flowable materials take place in regions located outside the regions of the emitter and the connecting means. It is proposed that a coating material is monolithically joined to the optical waveguide during at least one of the introductions. The invention further concerns an optical waveguide.

Abstract: The invention relates to a lighting unit that includes at least one light source and at least one rod-shaped optical waveguide following the light source, wherein each optical waveguide has at least one light emission surface. Each optical waveguide is flexible for this purpose. The present invention has developed a universally applicable, economical lighting unit for illuminating components.
