The invention relates to a light comprising a carrier () which has at least one lighting means () and which is arranged behind a light pane (). The aim of the invention is to form a light or a carrier which can be produced in a simple and economical manner and which can be mounted in a small space. The lighting means () are arranged on the carrier () in such a manner that they essentially correspond to the contour of the light pane () and the lighting means () is placed in a horizontal manner on one side of the carrier () so that the carrier () and the lighting means () require very little space. The carrier () and the light are used in motor vehicles.

Light, especially a rear light for motor vehicles, in addition to a carrier, preferably for said type of light

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&#x2014;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&#x2014;at a distance that is smaller than or equal to 35% of this distance&#x2014;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.

Method of producing LED bodies with the aid of a cross-sectional constriction

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.
