Abstract

The invention relates to a motor vehicle headlight, provided with light-emitting diodes in a first region, which are controlled by a first control unit for a first lighting function. The headlight also has a second range of light-emitting diodes, which are controlled by a second control unit for a second lighting function. Furthermore, a flat printed circuit board is provided with conductor tracks for connecting the light-emitting diodes to a respective control unit, wherein the light-emitting diodes are arranged together on one side of the printed circuit board.

Description

technical field

[0001] The invention relates to an automobile headlamp. Automotive headlights provide a variety of lighting functions. These lighting functions are, for example, low beam and high beam. Background technique

[0002] It is also known to use light-emitting diodes in headlights instead of, for example, xenon lamps. But there is only limited space in a car for headlights. DE 10 2007 031 934 A1 describes a headlight with a plurality of light-emitting diodes as light sources. However, it is difficult to arrange a sufficient number of light emitting diodes in a limited space so that a prescribed light intensity can be achieved. In addition, LEDs generate power losses, so heat dissipation is also an issue. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a motor vehicle headlight which is operated by means of light-emitting diodes and has sufficient light intensity.

[0004] The invention relates to ...
