Motor vehicle lighting with micro lens system

Abstract

A motor vehicle lighting device (1) for generating a light distribution comprises an optical imaging system (2) and at least one light source (3) associated with the optical imaging system, wherein the optical imaging system (2) comprises a collimator (4), An incoming lens (5) and an outgoing lens (6), wherein a collimator (4) is arranged between at least one light source (3) and the incoming lens (5) and is arranged for collimation by at least one light source ( 3) the generated light rays, so as to generate collimated light rays, and align the collimated light rays (7) on the incident lens (5) of the optical imaging system (2), wherein the incident The entry lens (5) has a plurality of micro-entry lenses (50 to 58) constructed in one piece with each other, wherein each micro-entry lens (50 to 58) is associated with a first optical axis (50a to 58a), wherein , all first optical axes (50a to 58a) extend in the same direction, which corresponds to the direction of propagation of the collimated light beam (7), wherein the exit lens (6) has a plurality of one-piece micro-exit lenses (60), wherein each micro-exit lens (60) is associated with a second optical axis (60a), wherein all second optical axes (60a) extend in the same direction, wherein each micro-exit lens The lens (50 to 58) has a light entrance surface (50b to 58b) facing the collimated light rays and a light exit surface (50c to 58c) facing the exit lens (6), wherein all light exit surfaces ( 50c to 58c) form a common, preferably planar surface (8), and each micro-exit lens (60) is associated with at least two differently configured micro-injection lenses (50 to 58) in such a way that the incident light on at least two The light rays (9a to 9c) on and through the at least two micro-injection lenses (50-58) of different configurations are only incident on the micro-injection lenses (50-58) associated with at least two Different partial regions of the light distribution are formed on the micro-exit lens (60) of the micro-injection lenses (50 to 58) of different configurations and after passing through the micro-exit lens (60).

Description

technical field [0001] The invention relates to a motor vehicle lighting device for generating a light distribution, comprising an optical imaging system (optische Abbildungssystem) and at least one light source associated with the optical imaging system, wherein the optical imaging system includes a collimator (Kollimator), an incident A lens (Eintrittsoptik) and an exit lens (Austrittsoptik), wherein a collimator is arranged between at least one light source and the entrance lens and is arranged to collimate (kollimieren, sometimes called collimation) the light produced by the at least one light source rays in order to generate collimated light rays in this way and to direct the collimated light rays onto the entrance lens of the optical imaging system, wherein the entrance lens has a plurality of micro Injection lenses, wherein each micro-injection lens is associated with a first optical axis (optische Achse), wherein all first optical axes extend in the same direction, pre...
