Abstract:
The invention relates to a motor vehicle illumination device (1) for generating light distribution, comprising an optical imaging system (2) and at least one light source (3) associated with the optical imaging system, in which: the optical imaging system (2) comprises a collimator (4), an incidence optical element (5) and an emergence optical element (6); the collimator (4) is arranged between the at least one light source (3) and the incidence optical element (5) and is designed to collimate light beams produced by the at least one light source (3) in order to produce collimated light beams, and to guide the collimated light beams (7) towards the incidence optical element (5) of the optical imaging system (2); the incidence optical element (5) comprises a plurality of integrally formed incidence micro-optical elements (50 to 58), a first optical axis (50a to 58a) being associated with each incidence micro-optical element (50 to 58) and all first optical axes (50a to 58a) extending in the same direction corresponding to the direction of propagation of the collimated light beams (7); the emergence optical element (6) comprises a plurality of integrally formed emergence micro-optical elements (60), a second optical axis (60a) being associated with each emergence micro-optical element (60) and all second optical axes (60a) extending in the same direction; each incidence micro-optical element (50-58) comprises a light incidence surface (50b to 58b) facing the collimated light beams and a light emergence surface (50c to 58c) facing the emergence optical element (6), all of the light emergence surfaces (50c to 58c) forming a common, preferably flat surface (8); and at least two differently formed incidence micro-optical elements (50 to 58) are associated with each emergence micro-optical element (60) in such a way that light beams (9a to 9c) hitting the at least two differently formed incidence micro-optical elements (50 to 58) and passing through said at least two differently formed incidence micro-optical elements (50 to 58) exclusively hit the emergence micro-optical element (60) associated with the at least two differently formed incidence micro-optical elements (50 to 58) and form different sub-regions of the light distribution after having passed though the emergence micro-optical system (60).
