A lighting device includes a facet body, the interior of which is translucent and which includes a surface made of a plurality of flat facets. The facet body is arranged on an opening formed in a cover that outwardly delimits an inner region of the lighting device. The surface of the facet body includes a first surface section and a second surface section, the first surface section is outwardly exposed via the opening and is translucent, and the second surface section lies in the inner region and has a reflective layer with the exception of one or more translucent surface regions. A plurality of light sources are arranged in the inner region such that the light sources emit light into the facet body via the translucent surface region(s) of the second surface section.
