Abstract

An illumination device for an interior fitting part of a motor vehicle includes a light guide bar that has a light entry surface along a longitudinal extension direction and a light source bar disposed on the light guide bar. The light source bar includes a plurality of point light sources that are disposed in series along the light entry surface, and a cover element that extends along the longitudinal extension direction of the light guide bar and shields at least one side surface of the light guide bar that differs from the light entry surface. The cover element is connected to the light guide bar via a first attachment element, the light source bar is connected to the light guide bar via a second attachment element, and the light source bar is at least partially housed between cover element and light guide bar.
