[0034] Figures 1 to 7 A first exemplary embodiment of the invention, a light module 10 for a motor vehicle headlight, is shown. exist figure 1 The light module 10 is shown with an open housing 19 , whereby an overview of the important optical components of the light module 10 is visible. figure 2 The optical components of the light module 10 and the optical paths of the plurality of laser beams, which are defined by these components, are shown.

[0035] The light module 10 contains a certain number of laser modules 11 (eg two to five, more generally one to ten or more, depending on the chosen implementation variant), as in particular in figure 2 as can be seen in . Each laser module 11 contains a laser light source Q ( Figure 5 ), the laser light source is in the form of a laser diode in the example shown; however, other known types of laser light sources can be used in a corresponding manner. For example, the laser modules 11 are arranged in a linear arrangement in t...

Abstract

The laser module ( 11 ) comprises a module body ( 21 ) with a head part ( 24 , 44 ) in which a laser light source ( 20 ) with a laser diode and associated collimator optics is fixed assembled in the accommodating space (22). The head part (24) forms a joint part of a ball joint with at least one joint face (25); a second joint part (30) with a corresponding joint face (35) belongs to the Support structure part (31) of laser module (11). The adjustment of the orientation of the laser source ( 20 ) is carried out by aligning the laser module ( 11 ) as a whole in a ball joint bearing formed by the two joint parts, and the alignment achieved thereby can be fixed by a permanent , preferably fixed by means of spot welding.

Description

technical field [0001] The present invention relates to a laser module for a vehicle headlight with a laser light source, preferably a laser diode, and an optical device associated with the laser light source, comprising at least one collimator. Furthermore, the invention relates to a laser source assembly for a vehicle headlight with a laser module and a support structure part for supporting the laser module. Likewise, the invention relates to a light module comprising a number of said laser source assemblies, and to a vehicle headlight with a light module and / or laser source assembly of said type. Background technique [0002] The use of laser light sources in motor vehicles, in particular for motor vehicle headlights, has become increasingly important, since laser diodes enable a more flexible and more efficient solution, whereby the luminous density of the light beam can also be significantly increased and light efficiency (Lichtausbeute). Accordingly, the laser light ...
