Problems solved by technology

By arranging the retaining block in the headlight housing, only an unfavorable heat dissipation is achieved and only an adjustment of the LED lighting module relative to the reflector section is made difficult or even impossible.
Especially in the case of impact loads on the headlights, misalignment can result because no direct coupling is provided between the retaining block and the reflector

Embodiment Construction

[0022] figure 1 An exemplary embodiment of a motor vehicle headlamp 1 with the features of the invention is shown. The headlight 1 has a housing 10 and can be fastened to the front of the vehicle by means of a receiving clip 24 in which the headlight 1 is received via the housing 10 . The headlight 1 is shown from the front and three LED illuminant modules 11 are arranged evenly distributed around the central axis 20 of the headlight 1 . The LED illuminant modules 11 are arranged at an angle of 120° relative to each other and are fastened to a reflector 12 of the headlight 1 . The reflector 12 has three reflector segments 12a, and each LED illuminant module 11 is assigned to one reflector segment 12a. The LED illuminant modules 11 each have a cooling receptacle 13 in which an LED illuminant is accommodated, which is directed toward the reflector section 12 a and is therefore not visible.

[0023] The light guide element 16 is inserted into the reflector 12 of the headlight ...

Abstract

The present invention relates to a headlight (1) for a vehicle having a housing (10) in which LED modules (11) and a reflector (12) are accommodated, wherein the LED modules (11) irradiate light into the reflector (12), and wherein the light is reflected at the reflector (12) and leaves the headlight (1). The invention provides that the LED modules (11) each have a cooling receptacle body (13), wherein the LED modules (11) are mounted on the reflector (12) by means of the respective cooling receptacle body (13).

Description

technical field [0001] The invention relates to a headlamp for a motor vehicle, said headlamp having a housing in which an LED lighting module and a reflector are accommodated, wherein the LED lighting module injects light into In the reflector, and wherein the light reflects off the reflector and exits the headlamp. Background technique [0002] A headlight for motor vehicles is known from DE 10 2007 061 304 A1, which has a housing, wherein an LED lighting module is mounted on the inner side of the housing. The LED illuminant modules emit light in the direction of the reflector, wherein the LED illuminant modules are arranged uniformly distributed at a distance from the central axis of the headlight on the periphery of the housing. The reflector is divided into four reflector segments, and each LED illuminant module emits light into the associated reflector segment. The shell for accommodating the LED lighting device module is made of metal material to achieve good heat c...
