In diesem Einsatzgebiet ist die Form der Beleuchtungseinrichtung an die Fahrzeugkontur angepasst. Den nötigen Freiheitsgrad ermöglicht ein flexibles Leitersubstrat wie zum Beispiel eine flexible Leiterplatte, die mit den Lumineszenzdioden bestückt und anschließend in die entsprechende Form gebracht wird. Da das flexible Leitersubstrat aufgrund seiner Biegsamkeit die benötigte Form nicht selbsttätig einnimmt ist die Montage jedoch sehr aufwendig. Deshalb wird das flexible Leitersubstrat zur Formgebung an einem die Form der Oberfläche des Leitersubstrats vorgebenden Substratträger befestigt.such Lighting devices are, for example, as vehicle lighting devices at the rear of a vehicle, for example as a taillight or brake light a passenger car (PKW) trained. In this application the shape of the illumination device is adapted to the vehicle contour. The necessary Degree of freedom a flexible conductor substrate, such as a flexible printed circuit board, equipped with the light-emitting diodes and then in the appropriate form is brought. Because the flexible conductor substrate due to its flexibility does not take the required shape automatically However, the assembly is very expensive. That is why it becomes flexible Ladder substrate for molding on a the shape of the surface of the Attached to the substrate substrate predetermining substrate carrier.
