- the LED light sources of the same group can be driven to control a Femlichtver notorious and a motorway light distribution.
- the basic idea of the invention is to assign a single optical unit to a group of LED light sources of the same size so that a plurality of light spots with the same vertical and / or horizontal critical angle are imaged in the vehicle apron to form at least two different light functions or light distributions. Characterized in that the LED light sources is assigned only a single optical unit, the headlight can be designed to save space.
- the LED light sources are arranged in a matrix-like manner in a plurality of horizontal and vertical rows on a common substrate, so that they are combined to form an LED array (LED array).
- a horizontal row of the LED light sources arranged on the substrate is imaged by means of the optical unit in such a way that a horizontal row of light spots is produced in the vehicle antechamber to form a light function, preferably a motorway light function.
- the predetermined light function can thus be generated with a number of identically sized LED light sources.
- At least two horizontal rows of LED light sources are arranged on the LED field and are imaged by means of the optical unit such that in the vehicle apron a first horizontal row of light spots to form the given motorway light function and immediately below the same arranged second horizontal Series of light spots is generated.
- a first horizontal row of light spots to form the given motorway light function and immediately below the same arranged second horizontal Series of light spots is generated.
- the LED light sources of a group of LED light sources are dimensioned in such a way and / or the optical unit has such an imaging characteristic that in the vehicle apron light spots are imaged with a horizontal critical angle and vertical critical angle of 0.28 °.
- a large number of light distributions can be generated with the size of these light spots.
- a quotient of vertical rows of LED light sources on the one hand and horizontal rows of LED light sources on the other hand is greater than four, so that a relatively large vehicle apron can be illuminated.
- the headlamp on a first group of LED light sources and a second group of LED light sources, wherein the two groups are arranged on a common substrate and wherein the LED light sources of the first group and the second group a different Dimension have.
- the dimension of the LED light sources of the second group of LED light sources is larger than the dimension of the LED light sources of the first group of LED light sources.
- the large-sized LED light sources of the second group for illuminating relatively large areas of the vehicle apron, such as for the high beam function, and the relatively small sized LED light sources of the first group of LED light sources for illumination of relatively small areas of the vehicle Vor- field, such as for the motorway light function, are used. Because the groups of LED light sources are assigned the same optical unit, the headlight has a relatively compact and space-saving design.
- At least one further LED light source is provided for generating a basic light distribution, such as a low-beam distribution.
- FIG. 1a is a schematic representation of a headlamp according to the invention according to a first embodiment

- the control unit 5 is associated with a switch unit 7, so that predetermined light distributions or light functions can be set manually or as a function of positions of the switch unit 7 located in the cockpit of the vehicle.
- a corresponding signal processing unit for processing the switching signals and / or the sensor signals is preferably provided.
- the headlamp on the one hand on a first light source 20 and the same associated optical unit 21 for generating a low beam distribution 9, which is exemplified in Figure 1 b on a set up to the headlights in 10 m distance measuring wall 18 is visible.
- the LED light source 20 may be formed, for example, as an LED chip with one or more LEDs.
- the headlight furthermore has a group of LED light sources 19 (LED chips) which are arranged on the substrate 2.

- the horizontal critical angle is the solid angle in a horizontal plane below which the light generated by a single LED light source 19 is radiated.
- a vertical limit angle is understood as meaning a solid angle under which light of the LED light source 19 is emitted in a vertical plane.
- the imaging characteristic of the optical unit 4 is selected such that thirteen horizontal rows a of light spots 10 and sixty-six vertical rows b of light spots 10 are formed.

- the second horizontal row a 2 of the light spots 10 can be used to generate a motorway light function 13.
- a number of LED light sources 19 of the corresponding row of LED light sources 19 are controlled by means of the drive unit 5 in such a way that the motorway light function 13 can be generated.
- the motorway light function 13 makes it possible to illuminate the vehicle apron 8 with an increased range in the middle region, the correspondingly controlled LED light sources 19 of the motorway light function 13 producing light spots 14 which lie above a bright-dark boundary HDG of the asymmetrical low-beam distribution 9.
- LED light sources 19 can be controlled, that are arranged below the light spots 14 arranged light spots of the horizontal row ai.
- such LED light sources 19 can be controlled so that light spots 15 in the first row ai are imaged to produce a dynamic cornering light.

- the first group of LED light sources 19 forms an LED field 21, which is imaged by the optical unit 4 to two horizontal rows ai, a 2 of light spots 10, wherein the light spots 10 have the same dimension as the light spots 10 according to the embodiment of Figure 1a and 1b.
- the second group of LED light sources 22 has a larger dimension than the LED light sources 19 of the first group, so that in cooperation with the same optical unit 4 light spots 16 are imaged with a horizontal and vertical limit angle of 0.5 °. These light spots 16 extend in a matrix-like manner above a horizontal light-dark boundary HDG of the low-beam light distribution 9. By driving the second group of LED light sources 22, a high-beam distribution 17 can thus be generated.
- a number of light spots 14 for forming the highway light function 13 and a number of light spots 15 for forming the cornering light function can be switched on.
- the range of the highway light function 13 can be controlled such that unwanted glare effects are suppressed.
- the LED light sources are arranged such that the second horizontal row a 2 of the light sources 10 in a vertical angle range between -0.28 ° and -0.57 °. This makes it possible to achieve an improved generation of the motorway light function 13.

- the LED light sources 22 of the second group of LED light sources 22 can also be dimensioned such that light spots with a vertical and / or horizontal critical angle between 0.2 ° and 1 ° are imaged.
- the light spots 16 produced by the second group of LED light sources 22 have interfaces about three times as long as the interfaces 11, 12 of the comparatively small spots 10. It is essential that the LED light sources 22 of the second group are larger than the LED light sources 19 of the first group, so that the number of light spots 16 formed thereby is smaller than the number of comparatively formed light spots 10 above the horizontal H.
- the LED Light sources 22 of the second group are arranged to the LED light sources 19 of the first group such that a lowermost horizontal row Ci of the large light spots 16 adjoins immediately above the second row a 2 of the small light spots 10. The lowest horizontal row Ci of the large light spots 10 is thus partially below the horizontal H. It can be seen that the first group of LED light sources 19 and the second group of LED light sources 22 produce partial light distributions or light patterns that are superimposed on the low beam distribution 9 of the further LED chip.
- LED light sources a horizontal rows of light spots b vertical rows of light spots
