Abstract
The present invention relates to an optical projection grid (1) for producing a light distribution, which projection grid (1) has a transmittance distribution, wherein the transmittance distribution is formed by subregions (2a, 2b . . . 2i) containing transparent structures (5) and opaque structures (4). A plurality of structures of each type is distributed, in particular in an incoherent and alternating manner, within a subregion (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, and 2i) and the ratio of transparent structures (5) to opaque structures (4) within a subregion (2a, 2b . . . 2i) is adjusted such that a transmittance index (T.sub.a, T.sub.b . . . T.sub.i) assigned to a subregion (2a, 2b . . . 2i) is achieved at least in a statistical mean.
