<p>The device (10) has a light guiding unit (12), which is limited by parallel main surfaces (14), where one of the main surfaces is arranged at a distance to the other surface. Illuminants (28) are arranged in such a manner that light emitted from the illuminants are coupled into the guiding unit. A reflection device (53) is provided on a side of the former main surface, and reflects the light in the direction to the interior of the guiding unit, where the reflection device has a reflector substrate (48) arranged on the side of the former surface, and a coupling layer and a reflection particle.</p> |
