Problems solved by technology

[0006]The disadvantage of the lighting modules described above is that with only one lighting module only a very limited number of light distributions are produced and thus the lighting function can be fulfilled (low efficiency)

Embodiment Construction

[0068] To improve readability, each plot is provided with a set coordinate system. Three directions are specified here: the horizontal direction H and the vertical direction V as well as the main emission direction Z of the motor vehicle lighting module.

[0069] The terms "upper", "lower", "vertical", "horizontal", etc. relate to the usual mounting positions of motor vehicle lighting modules in motor vehicles. The main emission direction Z corresponds, for example, to the forward movement direction of the motor vehicle when the motor vehicle lighting module is arranged in a motor vehicle headlight for generating at least one main light distribution.

[0070] first reference figure 1 , 1aand 2, more precisely with reference to those parts and aspects of the motor vehicle lighting module which apply equally to the first and the second embodiment. figure 1 , 1a and 2 each show a schematic view of a motor vehicle lighting module (or part of a motor vehicle lighting module) fo...

Abstract

The invention relates to a light module for a motor vehicle headlamp, comprising: at least one light source (1) and at least one projection device (2), the projection device (2) having an entry optical unit (21) and an exit optical unit (22), the entry optical unit (21) being designed to form an intermediate image from light emitted by the at least one light source (1) in an intermediate image plane, which lies between the entry optical unit (21) and the exit optical unit (22) and is substantially perpendicular to an optical axis of the projection device (2), and the exit optical unit (22) being designed to image the intermediate image into a region in front of the light module in the form of a light distribution of a first predefined type, at least one additional light source (3a, 3b, 3c,3d) being provided, which at least one additional light source (3a, 3b, 3c, 3d) is designed to emit light between the entry optical unit (21) and the exit optical unit (22); the exit optical unit (22) being designed to image the light emitted by the at least one additional light source (3a, 3b, 3c, 3d) into the region in front of the light module in the form of a light distribution of a second predefined type; the entry optical unit (21) and the at least one additional light source (3a, 3b, 3c, 3d) being designed in such a way and being associated with each other in such a way that neither the at least one additional light source (3a, 3b, 3c, 3d) nor the light emitted by the at least one additional light source (3a, 3b, 3c, 3d) changes the intermediate image.

Description

technical field [0001] The invention relates to a lighting module for a headlight of a motor vehicle for (preferably simultaneously) at least one main lighting function and at least one auxiliary lighting function, comprising at least one light source and at least one projection device, wherein the projection device has incident optics system and an exit optical system, wherein the incident optical system is arranged for, in an intermediate image plane between the incident optical system and the exit optical system, substantially transverse to the optical axis of the projection device, emitted from at least one light source The light of the light forms an intermediate image, and the exit optics are provided to image the intermediate image in the form of a first predetermined type of light distribution into the area in front of the illumination module. [0002] Furthermore, the invention relates to a motor vehicle headlight with at least one such lighting module. Background t...
