Abstract

In various embodiments, a lighting unit is provided. The lighting unit may include a hollow body made of a plastics material as a substrate, which hollow body has an outer surface and an opposite inner surface, wherein the latter at least partially delimits a hollow body internal volume, a plurality of light emitting diodes, which are arranged on the outer surface of the hollow body, and a conductor track structure, which is electrically conductively connected to the light emitting diodes. The conductor track structure is arranged on the inner surface of the hollow body, and the electrically conductive connection to the light emitting diodes is produced by through-contacts, which are passed through the plastics material.
