Microlens system for a motor vehicle headlight

Abstract

Microlens system (1) for a motor vehicle headlight, comprising a light source (12) for generating and emitting light, and a microlens device (2) which is arranged in the direction of light propagation downstream of the light source (12), wherein the light, when it strikes the microlens device (2), passes through the microlens device (2), wherein the microlens device (2) is configured to emit the light, wherein the microlens device (2) is composed of at least two layers, wherein a first layer (3) has a first light-entry surface (3b) facing the light source (12), and a first light-emission surface (3a) which is formed from a plurality of first microlenses (4), wherein the first microlenses (4) are arranged relative to each other such that the optical axes of the first microlenses (4) are each oriented parallel to each other, wherein a second layer (5) has a second light-entry surface (5a),which faces the first light-exit surface (3b), and has a second light-exit surface (5b), wherein the second light-entry surface (5a) is formed from a plurality of second microlenses (6), wherein the second microlenses (6) are arranged to each other such that the optical axes of the first (4) and second microlenses (6) are oriented parallel to each other, wherein the first microlenses (4) are convex and the second microlenses (6) are correspondingly concave, wherein the first light-exit surface (3b) contacts the second light-entry surface (5a) over its entire area such that each convex microlens (4) contacts a corresponding concave microlens (6) over its entire area, wherein the first layer (3) comprises a material with a first refractive index and the second layer (5) comprises a material with a second refractive index, wherein the first and second refractive indices are different, characterized in thatthat an optical element (11) is arranged between the light source (12) and the microlens device (2) and is configured to refract the light rays emitted radially by the light source (12) in such a way that the light rays, after passing through the optical element (11), are oriented parallel to each other and parallel to the optical axes of the first (4) and second microlenses (6) of the microlens device (2).
