Problems solved by technology

[0003] Disadvantageously, the mounting of the heat sink on the light module increases the weight on the one hand and the size of the light module on the other hand, making the installation of the light module into the headlight housing difficult.
The installation of the heat sink on the lamp module is therefore particularly disadvantageous, even if the lamp module is pivotable for adjusting the emitted light.

Embodiment Construction

[0027] figure 1 A motor vehicle headlight 1 according to the invention with a headlight housing 2 in which at least one light module 3 is arranged is shown in a schematic, clearly simplified illustration. The lamp module 3 has a luminous means 4 , wherein at least one laser diode 5 is preferably provided as the luminous means 4 . However, other light emitting means 4 can also be used, for example light emitting diodes, DLP components or the like. The luminous means 4 are fastened on a carrier frame 6 . Furthermore, the motor vehicle headlight 1 includes at least one cooling element 7 which is provided for extracting heat from the light module 3 . The cooling element 7 is arranged on the headlight housing 2 in such a way that the heat extracted by the lamp module 3 is emitted outside the headlight housing 2 . The cooling element 7 has a cooling body 8 and cooling fins 9 , wherein the cooling fins 8 are arranged outside the headlight housing 2 . The heat sink 8 is arranged a...

Abstract

The invention relates to a motor vehicle headlamp. The invention relates to a motor vehicle headlight (1) having a headlight housing (2) and at least one cooling element (7), wherein at least one lampmodule (3) is arranged in the headlight housing (2), the lamp module (3) has a lighting means (4), the cooling element (7) is used for extracting heat from the lamp module (3), the cooling element (7) is arranged on the headlight housing (2) in such a way that the heat emitted by the light module (3) is emitted outside the headlight housing (2), the cooling element (7) is arranged at a distance from the light module (3) and is connected to the light module (3) via a connecting device (11), and the connecting device (11) is thermally conductive.

Description

technical field [0001] The invention relates to a motor vehicle headlight with a headlight housing and at least one cooling element, in which at least one lamp module is arranged, wherein the lamp module has a luminous means and the cooling element Provision is made to extract heat from the lamp module, wherein the cooling element is arranged on the headlight housing in such a way that the heat extracted by the lamp module is emitted outside the headlight housing. Background technique [0002] In the case of typical motor vehicle headlights known from the prior art (as indicated, for example, in WO 2015 / 024839 A1), in which the light module has, for example, a light-emitting diode, a laser diode, a DLP (Digital Light Processing) components or the like, a corresponding cooling of the light-emitting device must be achieved. For this purpose, a cooling element is usually provided, which is fastened to the lamp module. For example, Peltier elements or cooling bodies with cooli...
