Summary of the Invention

Problems to be Solved by the Invention

[0006] To form a distinct distinction between individual light segments, it is known to form a relatively large gap between individual optical elements or to arrange a shielding element or a blind (light-shielding element) between the optical elements along the direction of light propagation. By arranging the blind or applying a large gap, the light from different optical elements can be more easily distinguished by an observer, and as a result, a clear and sharp visualization (imaging) of the individual segment(s) of the segmented light function can be obtained. However, the blind and the shielding element make the entire lighting device more complex, and it is difficult to apply and fix such components to a vehicle lamp because the vehicle lamp is subject to vibrations and other mechanical forces. The alternative of providing a considerably large gap between individual optical elements deteriorates the optical impression of the overall light function assembled from multiple segments.

[0007] An object of the present invention is to provide a vehicle lighting device capable of forming a segmented light function and having an improved and simplified structure at the same time.
