The invention relates to an optical structure (100) for a motor vehicle headlight lighting device (1) that is set up to emit light forming a specified light pattern (LP1), wherein the optical structure (100) of the lighting device (1) is associated with the lighting device (1), or is part of it in such a way, that the optical structure (100) is transilluminated by essentially the entire luminous flux of the lighting device (1), and wherein the optical structure (100) consists of a number of optical structural elements (110) that have a light-scattering effect and that are designed in such a way that the unmodified light pattern (LP1) produced by the lighting device (1) is modified by the optical structure (100) into a specifiable modified light pattern (LP2), and wherein the optical structural elements (110) have a quadrilateral base area (202), i.e., the area (202) between the vertices (201) of a quadrilateral grid (200) is completely covered by the base area of exactly one optical structural element (110). |

1. An optical structure (100) for a motor vehicle headlight lighting device (1) that is set up to emit light forming a specified light pattern (LP1), wherein the optical structure (100) of the lighting device (1) is associated with the lighting device (1), or is part of it in such a way, that the optical structure (100) is transilluminated by essentially the entire luminous flux of the lighting device (1), and wherein:
the optical structure (100) consists of a number of optical structural elements (110) that have a light-scattering effect and that are designed in such a way that the unmodified light pattern (LP1) produced by the lighting device (1) is modified by the optical structure (100) into a specifiable modified light pattern (LP2), the optical structural elements (110) have a quadrilateral base area (202), i.e., the area (202) between the vertices (201) of a quadrilateral grid (200) is completely covered by the base area of exactly one optical structural element (110), the base area of each optical structural element (110) is formed by a rectangle or a square, and characterized in that the structural elements (110) have, in their vertex areas, vertex area elevations (110b), each of which is formed by a lateral face of a pyramidal elevation (111b), and have, in their centers, a central elevation (110a). |
