Abstract

Disclosed is a projection apparatus (2) for a lighting module (1) of a motor vehicle headlamp. The projection apparatus (2) is formed by a plurality of micro-optical systems (3) that are arranged likea matrix, and each micro-optical system (3) includes a micro-input optical element (30), a micro-output optical element (31) associated with the micro-input optical element (30), and a micro-diaphragm (32); all micro-input optical elements (31) form an input optical unit (4), all micro-output optical elements (31) form an output optical unit (5), and all micro-diaphragms (32) form a diaphragm device (6); the diaphragm device (6) is disposed in a plane extending substantially perpendicularly to the main direction of emission (Z) of the projection apparatus (2), while the input optical unit (4), the output optical unit (5) and the diaphragm device (6) are disposed in planes extending substantially parallel to one another; all of the micro-optical systems (3) are subdivided into at least twomicro-optical system groups (G1, G2, G3), and the micro-diaphragms (32) of the micro-optical systems (3) of each micro-optical system group (G1, G2, G3) can be imaged by means of light having at least one optical wavelength (lambdaG, lambdaG2, lambdaG3) lying within a predefined optical wavelength range, and the predefined optical wavelength ranges are different in different micro-optical systemgroups (G1, G2, G3).

Description

technical field [0001] The invention relates to a projection device for an optical module of a motor vehicle headlamp, the projection device is formed by a plurality of micro-optical systems arranged in a matrix, wherein each micro-optical system has a micro-incidence optical device, a micro-incidence Optics associated micro-exit optics and micro-apertures disposed between the micro-entry optics and the micro-exit optics, wherein all the micro-entry optics form the entry optics, all the micro-exit optics form the exit optics, and all The micro-aperture forms an aperture arrangement, wherein the aperture arrangement is arranged in a plane substantially orthogonal to the main emission direction of the projection device, and the entry optics, exit optics and aperture arrangement are arranged in planes substantially parallel to each other. [0002] Furthermore, the invention relates to a light module having at least one such projection device. Background technique [0003] A pr...
