Abstract

A lighting element for a passenger compartment of a motor vehicle includes a diffuser; an elongated light guide, wherein the light guide is at least partially accommodated in the diffuser; and a reflector arranged on an inner side of the diffuser and having a reflective surface facing the light guide. The reflector is configured to reflect light from the light guide to an outer side of the light guide. The reflector has a rough surface in order to reflect light from the light guide diffusely.
