The present invention relates to a light-guiding system for improving the lighting
conditions of the passenger compartment of a motor vehicle, including a light-generating
unit (3) which can be switched on and off electrically and a light guide
(5) which is used for guiding the light and which is coupled to the light-generating
unit (3) for coupling in the light. According to the present invention,
the light guide (5) is arranged in the area of the interior lining of the
vehicle roof (1) and designed as a flat light guide, the light being coupled
in at one or more lateral surfaces (7, 8) of the light guide (5);
and the flat light guide (5) being prepared such that the light couples
out of the light guide (5) into the passenger compartment (2) of
the vehicle over a large surface and in a homogeneous manner.
