[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 light module 10 and the beam path of a plurality of laser beams are shown, which are defined by these components.

[0035] The light module 10 contains a certain number of laser modules 11 (for example two to five, more generally one to ten or more, depending on the selected implementation variant), as in particular in figure 2 as can be seen in the . Each laser module 11 includes a laser light source Q ( Figure 5 ), the laser light source is designed as 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 ...

Abstract

A laser module (11) includes a module body (21) having a head part (24, 44), in which a laser source (20) having a laser diode and associated collimator optical system is mounted in a fixed manner ina receiving space (22). The head part (24) forms a joint part of a ball joint comprising at least one joint surface (25); a second joint part (30) comprising a corresponding joint surface (35) belongsto a bearing component (31) for the laser module (11). The orientation of the laser source (20) is set by adjusting the laser module (11) as a whole in the ball joint mounting formed by the two jointparts, and the adjustment thus achieved can be fixed by a permanent fixing, preferably by means of point welding.

Description

technical field [0001] The invention relates to a laser module for a vehicle headlight with a laser light source, preferably a laser diode, and an optical system associated with the laser light source including at least one collimator. Furthermore, the invention relates to a laser source assembly for a vehicle headlight with a laser module and a carrier structural 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 a laser source assembly of said type. Background technique [0002] The use of laser light sources in motor vehicles, in particular for motor vehicle headlights, is becoming more and more important nowadays, since laser diodes allow for more flexible and efficient solutions, which can also significantly increase the luminous intensity of the light beam and light efficiency (Lichtausbeute). Accordingly, the laser light sour...
