An optical system comprising a light guide and a diaphragm and force vehicle illumination a direction with such an optical system

摘要

The present invention relates to an optical system comprising a flat plate-like light guide (1) made of a transparent material, in particular glass or plastic, and a at a distance from the light exit surfaces (4, 5) of the light guide (1) located aperture (110) with an optically permeable regions (111, 112), through which the from the light guide (1) via the exit surfaces (4, 5) coupled-out light passes through. Thus the optically transparent regions (111, 112) for an observer as homogeneously as possible and uniformly bright appearance, it is proposed that the light guide (1) projecting side arms (2, 3), on the distal ends of the light outlet surfaces (4, 5) are formed, that the outcoupling (6, 7) as recesses in the light guide (1) are formed, which in the light guide (1) coupled-in light in the side arms (2, 3) of a deflection, and that a distance between the decoupling grid elements (6, 7) and the optically permeable regions (111, 112) for each of the side arms (2, 3) is the same.
