Abstract
The invention relates to a lighting device and a method of manufacturing such a lighting device. The lighting device () comprises a first light emitting element () being optically coupled to a light guide () having an out-coupling surface () for illumination via the light guide. Further, the lighting device comprises a second light emitting element () dedicated for direct illumination from the lighting device. The invention is advantageous in that the lighting device provides both a decorative look and a functional illumination, and is still energy-efficient since the light emitted from the second light emitting element is directly emitted from the light emitting element without unnecessary energy-loss.
