Description

[0001] The invention relates to a headlight arrangement for a vehicle, in particular a single-track vehicle, comprising a high beam device and a low beam device, and optionally a cornering light device, and optionally a daytime running light device and optionally another homologated lighting device, each with at least one light source, wherein a compensation light device is provided which is designed to compensate for a change, preferably shortening, of a light cone of the headlight arrangement caused by an inclination of the vehicle, wherein the compensation light device comprises at least one light source and a vehicle with such a headlight arrangement.

[0002] With vehicles, especially single-track vehicles like motorcycles, a problem arises regarding road illumination: the light beam emitted by a headlight assembly changes when the vehicle is tilted. This results in insufficient illumination of the road.

[0003] A relevant tilting of a vehicle occurs, for example, during acceleration in or against the direction of travel. Acceleration in the direction of travel would be, for instance, the acceleration process of a vehicle. In this case, a headlight assembly would tilt upwards and the light beam would change, specifically: lengthen.

[0004] Acceleration against the direction of travel occurs, for example, during a braking maneuver, where deceleration forces act on the headlight assembly, causing it to tilt downwards. This downward tilt, towards the road, shortens the light cone of the headlight assembly, and the road is no longer adequately illuminated.

[0005] In such a case, the tilt is about a pitching axis. That is, the vehicle's tilt essentially corresponds to a pitching angle.

[0006] Even when cornering, the vehicle can tilt, which can lead to a change in the light beam.

[0007] To counteract a shortening of the headlight beam and ensure sufficient illumination of the road, DE 10 2019 104 854 proposes the provision of a compensating light device. Such a compensating light device is designed as an additional and separate unit below the high beam and low beam devices. In other words, in addition to the light sources of the high beam and low beam devices, further light sources are provided to compensate for a shortening of the light beam. These can then emit light when the vehicle is tilted accordingly, thus compensating for the shortening of the headlight beam.

[0008] The main disadvantage is that such an additional compensating light device, with its own separate light sources from the high beam and low beam (and any cornering or daytime running lights), is not eligible for type approval. This means that such a headlight arrangement, and consequently a vehicle equipped with it, cannot receive homologation and therefore type approval (in the European Union) according to the currently valid EU Regulation (EU) 2018 / 858. Therefore, such vehicles are not eligible for registration anywhere in the European Union.

[0009] Furthermore, a compensating light device according to DE 10 2019 104 854 requires additional material and increased space in a headlight arrangement due to the additional light sources provided.

[0010] The object of the invention is to at least partially overcome the aforementioned disadvantages and to provide an improved headlight arrangement that is homologable and thus eligible for approval, at least within the European Union. Furthermore, a vehicle equipped with such a headlight arrangement is to be specified.

[0011] This problem is solved by the features of claims 1 and 10.

[0012] According to the invention, it is therefore provided that the at least one light source of the compensation light device is formed by at least one of the at least one light source of the high beam device and / or the low beam device and / or the cornering light device and / or the daytime running light device and / or the other homologated light device.

[0013] Therefore, only existing light sources are used for the compensating lighting device, which are already homologated or can be homologated. This makes it possible to provide a road-legal headlight assembly with a compensating lighting device to compensate for a shortening of the headlight beam caused by a tilt of the vehicle.

[0014] Furthermore, no additional light sources, components, or the like are required for the compensating lighting device, meaning it can be implemented without additional material costs and with minimal space requirements. This also minimizes costs.

[0015] The at least one light source of the high beam device and / or the low beam device and / or the cornering light device and / or the daytime running light device and / or the other homologated light device therefore fulfills a dual function.

[0016] For the purposes of this application, a homologated lighting device is a lighting device with a light source that is eligible for approval or authorization, both individually and in combination with a headlight assembly, and has therefore received or is eligible for type approval (in the European Union) in accordance with the currently valid EU Regulation (EU) 2018 / 858. Lighting devices that are eligible for approval or authorization under future laws or regulations are also included in the term "homologated lighting device".

[0017] A light source within the meaning of the present application is, in principle, an element that forms a single light source, for example, a light-emitting diode. However, it is also possible for a light source to form multiple light sources and, for example, to consist of a plurality of light-emitting diodes.

[0018] In a vehicle according to the invention, it is provided that it has a headlight arrangement according to the invention. Thus, a vehicle, preferably a single-track vehicle, can be provided which has a road-legal compensating light device.

[0019] Further advantageous embodiments of the invention are defined in the dependent claims.

[0020] Advantageously, the high beam device may be provided to have at least one first high beam module and at least one second high beam module, each with at least one light source, wherein the compensating light device comprises at least one light source of the at least one first high beam module and / or of the at least one second high beam module.

[0021] By providing at least two high beam modules, one of the high beam modules can be configured primarily for the emission of high beam, while the other of the high beam modules can be configured primarily for the emission of light via the compensation light device.

[0022] Specifically, this can mean, for example, that at least one light source of the first high beam module is operated at essentially full power in a high beam mode in which high beam is emitted by the headlight assembly, while at least one light source of the second high beam module is operated at reduced power compared to full power.

[0023] In a compensation light mode, in which a shortening of the headlight beam caused by a vehicle's tilt is compensated for, at least one bulb of the second high beam module can operate at full power, while the bulb of the first high beam module operates at a reduced power level. It is also conceivable that the first high beam module is not used at all in compensation light mode, i.e., it emits no light.

[0024] In one embodiment, the low beam device may have at least one first low beam module and at least one second low beam module, each with at least one light source, wherein the compensating light device comprises at least one light source of the at least one first low beam module and / or of the at least one second low beam module.

[0025] By providing at least two low beam modules, the light output of the low beam device in compensation light mode can be adjusted via one of the low beam modules to achieve the best possible illumination of the road.

[0026] Specifically, this can mean, for example, that at least one light source of the first low beam module can be operated in a light compensation mode with reduced power compared to the low beam mode.

[0027] This prevents excessive illumination of the area directly in front of a vehicle, and any resulting glare for the driver of the vehicle.

[0028] Preferably, it can be provided that the at least one first high beam module and the at least one second high beam module are arranged spatially apart from each other and / or wherein the at least one first low beam module and the at least one second low beam module are arranged spatially apart from each other.

[0029] This allows the high beam modules and / or low beam modules to be positioned within the headlight assembly in such a way as to achieve the best possible illumination of the road.

[0030] It may also be provided that the at least one first low beam module and the at least one second low beam module are designed to be spaced apart from each other.

[0031] Similarly, it can also be provided that the at least one first high beam module and the at least one second high beam module are designed to be spaced apart from each other.

[0032] These features also contribute to the most optimal possible arrangement of the high beam modules or the low beam modules within the headlight assembly.

[0033] Preferably, the at least one first low-beam module can be arranged in the direction of gravity below the at least one second low-beam module. In other words, the first low-beam module can be arranged closer to a road surface than the second low-beam module.

[0034] Similarly, it can also be provided that the at least one first high beam module is arranged below the at least one second high beam module in the direction of gravity. In other words, the first high beam module can be arranged closer to a road surface than the second high beam module.

[0035] This allows different areas of the roadway to be illuminated by different high beam modules or low beam modules.

[0036] In a particularly preferred embodiment, at least two, preferably exactly two, first low-beam modules and at least two, preferably exactly two, second low-beam modules are provided.

[0037] The at least two first low beam modules and / or the at least two second low beam modules can be designed to be mirror-symmetrical or identical to each other.

[0038] In a particularly preferred embodiment, at least two, preferably exactly two, first high beam modules and at least two, preferably exactly two, second high beam modules are provided.

[0039] The at least two first high beam modules and / or the at least two second high beam modules can be designed to be mirror-symmetrical or identical to each other.

[0040] These features, individually or in combination, contribute to enabling the best possible illumination of the roadway.

[0041] In one embodiment, it can be provided that the cornering light device has at least one first cornering light module and at least one second cornering light module, each with at least one light source.

[0042] Cornering lights are used to achieve better illumination of the road when driving around curves and are generally already known.

[0043] If a first and a second cornering light module are provided, the first cornering light module can be used, for example, for sufficient illumination in left-hand bends and the second cornering light module for sufficient illumination in right-hand bends.

[0044] The first cornering light module and the second cornering light module can be designed to be mirror-symmetrical or identical to each other.

[0045] Daytime running lights are designed to emit daytime light, primarily not for illuminating the road, but for improving the vehicle's visibility to other road users. Such daytime running lights are already known from the prior art.

[0046] Advantageously, it may be provided that the cornering light device and / or the daytime running light device and / or the homologated lighting device is designed separately from the low beam device and / or the high beam device.

[0047] In particular, the cornering light device and the daytime running light device can also be designed separately from each other.

[0048] Furthermore, it is advantageously provided that the cornering light device and / or the daytime running light device and / or the low beam device and / or the high beam device and / or the homologated light device are spatially spaced apart from each other.

[0049] In a preferred embodiment, it can be provided that the low beam device and / or the high beam device and / or the cornering light device and / or the daytime running light device and / or the homologated light device and / or the compensation light device has more than one light source, i.e., at least two light sources.

[0050] The at least one first low beam module and / or the at least one second low beam module and / or the at least one first high beam module and / or the at least one second high beam module and / or the at least one first cornering light module and / or the at least one second cornering light module also preferably have more than one light source, i.e. at least two light sources.

[0051] The light sources preferably include at least one light-emitting diode or are formed by at least one light-emitting diode.

[0052] This is advantageous because LEDs can be controlled and / or regulated relatively easily, for example via pulse-width modulation. Thus, the power output of the LEDs can be changed in a simple way.

[0053] The power output of a light source is proportional to its luminous flux; that is, higher power output results in a higher luminous flux, and vice versa. Therefore, it is clear to a professional that if, for example, the power output of a light source is reduced or increased, this will inevitably lead to a corresponding reduction or increase in its luminous flux.

[0054] It may also be provided that the light sources of the dipped beam device and / or the main beam device and / or the cornering light device and / or the daytime running light device and / or the homologated light device and / or the compensation light device are additionally assigned to at least one other of the aforementioned devices.

[0055] For example, in high beam mode, the bulbs of the low beam system can also emit light.

[0056] According to a further embodiment, the headlight arrangement can be provided to have at least one first headlight module with a first focal length and at least one second headlight module with a second focal length, wherein the first focal length and the second focal length are different from each other.

[0057] Different areas of the road can be illuminated using different headlight modules, thus achieving the best possible illumination of the road.

[0058] The first headlight module can be positioned below the second headlight module in the direction of gravity. In other words, the first headlight module can be positioned closer to the roadway than the second headlight module.

[0059] In particular, it may also be provided that the second focal length is greater than the first focal length.

[0060] Advantageously, at least two first headlight modules with a first focal length and at least two second headlight modules with a second focal length are provided.

[0061] It may be provided that the at least two first headlight modules and / or the at least two second headlight modules are arranged next to each other.

[0062] A headlight module can comprise at least one lens, preferably at least two lenses, and at least one aperture.

[0063] The aperture can block at least part of the light emitted by at least one of the light sources to prevent light from being emitted in unwanted directions. The lens can be used to collect or diffuse the light emitted by the light sources.

[0064] If at least two lenses are provided, one of the lenses can scatter the light emitted by the light sources and the other lens can collect the light emitted by the light sources.

[0065] Advantageously, the light emitted by the light sources first passes through an aperture, is then diffused, and subsequently focused. It can therefore be provided that, in the direction of light emission, at least one aperture is arranged in front of a first, preferably diffusing, lens, and the first lens is arranged in front of a second, preferably converging, lens.

[0066] According to a preferred embodiment, it can be provided that the at least one first high beam module and / or the at least one first low beam module is assigned to the at least one first headlight module and that the at least one second high beam module and / or the at least one second low beam module is assigned to the at least one second headlight module.

[0067] This allows the low beam modules and / or high beam modules to be adapted to the different focal lengths of the headlight modules in order to achieve the best possible illumination of the road.

[0068] Preferably, it can be provided that a luminous flux emitted by the low beam device and / or the high beam device, preferably the at least one light source of the low beam device and / or the high beam device, is variable.

[0069] This allows the high beam device and / or the low beam device or their light sources to emit different luminous fluxes in different operating modes.

[0070] Advantageously, the luminous flux emitted by the cornering light device and / or the daytime running light device and / or the homologated lighting device, preferably the at least one light source of the low beam device and / or the high beam device and / or the homologated lighting device, can also be varied.

[0071] A change in luminous flux can be achieved, for example, by changing the power supplied to the light sources.

[0072] According to a further embodiment, the headlight arrangement can be operated in a low beam mode, in which low beam is emitted by the headlight arrangement, a high beam mode, in which high beam is emitted by the headlight arrangement, and a compensation light mode, in which a shortening of a light cone of the headlight arrangement caused by a tilting of the vehicle is compensated for, wherein a luminous flux emitted by the low beam device and / or by the high beam device in the compensation light mode is different from a luminous flux emitted in the low beam mode and / or high beam mode.

[0073] This means that, depending on the operating mode of the headlight assembly, the low beam and / or high beam can emit different luminous fluxes. Thus, different illumination of the road can be achieved by varying the emitted luminous flux through the different operating modes.

[0074] Similarly, this can also apply to the cornering light device and / or the daytime running light device and / or any other homologated lighting device. That is to say, the luminous flux emitted by the cornering light device and / or the daytime running light device and / or any other homologated lighting device in compensation light mode may differ from that emitted in low beam mode and / or high beam mode and / or cornering light mode and / or daytime running light mode.

[0075] In cornering light mode, the cornering light system emits light to better illuminate the road when driving around curves. In daytime running light mode, the daytime running light system emits daytime running lights to improve the vehicle's visibility.

[0076] The change in luminous flux between the different modes can be achieved by changing the power supplied to the light source. If multiple light sources are used, the luminous flux can also be changed, or alternatively, by only partially using individual light sources.

[0077] With regard to a vehicle according to the invention, it can be provided that the vehicle has at least one sensor for detecting an inclination, preferably a pitch angle, of the vehicle, preferably wherein the sensor is part of an anti-lock braking system of the vehicle.

[0078] A sensor can therefore be used to determine the vehicle's inclination, in order to then operate the headlight arrangement in a compensation light mode.

[0079] Advantageously, at least one of the sensors is a sensor that is already used in other existing systems on the vehicle, such as an anti-lock braking system.

[0080] The at least one sensor could be, for example, a tilt sensor, an acceleration sensor, a (wheel) speed sensor, or an optical sensor.

[0081] Preferably, more than one sensor can be provided, preferably at least two different sensors. This allows a large number of different sensor data to be collected in order to determine the vehicle's condition as comprehensively as possible, particularly with regard to vehicle tilt.

[0082] In another embodiment, the vehicle can have a control device by means of which the headlight system can be controlled and / or regulated.

[0083] In particular, the control device can be designed to receive and / or process sensor data from at least one sensor and to control and / or regulate the headlight device depending on the sensor data.

[0084] The control device can preferably also be used to control the high beam device and / or the low beam device and / or the cornering light device and / or the daytime running light device and / or the other homologated lighting device and / or the compensation lighting device.

[0085] Preferably, the individual light sources of the headlight assembly can be controlled via the control device.

[0086] In a method for compensating for a change, preferably shortening, of the light cone of a headlight assembly caused by a tilting of a vehicle, it can be provided that, when a predefined limit value of a tilt, preferably a pitch angle, of the vehicle is exceeded, in addition to the low beam emitted by the low beam device, light from at least one light source of the high beam device and / or the low beam device and / or the cornering light device and / or the daytime running light device and / or the other homologated light device is emitted via the compensation light device in order to compensate, preferably completely, for a change, preferably shortening, of the light cone of the headlight assembly caused by a tilting of the vehicle.

[0087] With such a method, it is possible to compensate for a shortening of the light cone of the headlight arrangement caused by a tilting of the vehicle, using only existing and homologated light sources.

[0088] Regarding a method, it may further be provided that the predefined limit value corresponds to a vehicle inclination of 1° to 8°, preferably 4°, relative to the vehicle's normal position. The vehicle's normal position is the position in which the vehicle is, for example, stationary and in which sufficient illumination of the road surface is provided in low beam or high beam mode.

[0089] Furthermore, it may be provided that if the predefined limit value of the vehicle's inclination is exceeded, the luminous flux emitted by the low beam device as low beam is reduced.

[0090] This prevents excessive illumination of the area directly in front of a vehicle, and any resulting glare for the driver of the vehicle.

[0091] Preferably, it can be provided that a luminous flux emitted via the compensation light device from the at least one light source of the high beam device differs from a luminous flux emitted by the same light source as high beam, preferably at least twice as large as the latter.

[0092] This is particularly advantageous if the high beam device has multiple bulbs. In this case, one bulb can be operated at reduced power in high beam mode, and then at full power in compensation mode to compensate for a greater shortening of the light beam.

[0093] Advantageously, it can also be provided that a luminous flux emitted via the compensation light device by at least one light source of the high beam device and / or the low beam device and / or the cornering light device and / or the daytime running light device and / or the other homologated light device is regulated depending on the inclination of the vehicle.

[0094] Therefore, exceeding the predefined limit does not simply result in a switch from low beam or high beam mode to a static compensation light mode. Rather, the light output in the compensation light mode can be regulated in such a way that the illumination is optimal in every inclination position of the vehicle.

[0095] Further details and advantages of preferred embodiments of the invention are explained in more detail below with reference to the figures and the drawings. These show: Fig. 1 a schematic representation of a vehicle, Fig. 2 a schematic representation of a headlight arrangement, Fig. 3a a schematic representation of a first part of the headlight arrangement, Fig. 3b an exploded view of the Fig. 3a, Fig. 4a a schematic representation of a second part of the headlight arrangement, Fig. 4b an exploded view of the Fig. 4a, and Fig. 5 a schematic representation of an arrangement of light sources of the headlight arrangement.

[0096] The Fig. Figure 1 shows a schematic representation of a vehicle 100. It can be seen that the vehicle 100 is designed as a single-track vehicle, specifically a motorcycle. A headlight assembly 1 is arranged at the front of the vehicle 100 to illuminate an area in front of the vehicle, in particular a roadway.

[0097] The headlight assembly 1 can, in principle, be fitted to a wide variety of vehicles, for example, multi-track vehicles such as cars, motor tricycles, or snowmobiles, or single-track vehicles such as motorcycles, snowmobiles, bicycles, or the like. The vehicles may have tires, tracks, and / or skis. The vehicles may be motorized, for example, by means of an internal combustion engine and / or an electric motor, or they may not have a motor.

[0098] The Fig. Figure 2 shows a schematic representation of a headlight arrangement 1. It can be seen that the headlight arrangement 1 comprises two first headlight modules 13 and two second headlight modules 14.

[0099] The first and second headlight modules 13, 14 are each arranged next to each other, while the first headlight modules 13 are arranged below the second headlight modules 14 in the direction of gravity.

[0100] The first headlight module 13 has a first focal length, and the second headlight module 14 has a second focal length. In this embodiment, the second focal length is greater than the first focal length. However, other configurations are also conceivable.

[0101] Furthermore, it can be seen that the headlight arrangement 1 has a first part 1a and a second part 1b, wherein the first headlight modules 13 are assigned to the first part 1a and the second headlight modules 14 to the second part 1b.

[0102] The two parts 1a, 1b of the headlight assembly 1 further comprise a first circuit board 1c and a second circuit board 1d on which various components can be arranged.

[0103] It is also recognizable as part of a daytime running light device 5 on the second circuit board 1d.

[0104] The Fig. Figure 3a shows a schematic representation of a first part 1a of the headlight arrangement 1, which Fig. 3b an exploded view of it.

[0105] It can be seen that the first headlight modules 13 each comprise a first lens 13a and a second lens 13b. It is possible that the first lens 13a is a diverging lens and the second lens 13b is a converging lens.

[0106] The first lens 13a is arranged in a first holder 15. The first holder 15 is attached to the first circuit board 1c and has openings for the passage of light. A shutter 13c is positioned upstream of the first holder 15, and thus of the first lens 13a, which can partially block the light emitted from the light sources 7a, 9a, 11a, and 11b.

[0107] The aperture 13c includes several slot-shaped recesses behind which the light sources 7a, 9a, 11a, 12a are arranged.

[0108] A lens holder 13d, which positions lenses 13a and 13b at the correct distance from each other, is located downstream of the first lens 13a. The lens holder 13d also serves to hold the second lens 13b. The lens holder 13d is also arranged on the first circuit board 1c.

[0109] The first circuit board 1c also has openings 15 through which a lens holder 14d of the second headlight modules 14 can protrude.

[0110] The electrical components arranged on the first circuit board 1c form at least parts of the high beam device 2, the low beam device 3, the compensation light device 6, the cornering light device 4 and / or the daytime running light device 5.

[0111] In this embodiment, the high beam device 2 comprises two first high beam modules 7 and two second high beam modules 8, the low beam device 3 comprises two first low beam modules 9 and two second low beam modules 10, and the cornering light device 4 comprises a first cornering light module 11 and a second cornering light module 12.

[0112] The first high beam modules 7, the first low beam module 9, the first cornering light module 11, and the second cornering light module 12 are all assigned to the first part 1a of the headlight assembly. Accordingly, their light sources 7a, 9a, 11a, and 12a are arranged on the first circuit board 1c.

[0113] The light sources 7a, 9a, 11a and 12a are arranged on the first circuit board 1c in such a way that they can emit their light via the first lenses 13a and second lenses 13b of the first headlight modules 13. The exact arrangement of the light sources is described in the Fig. 5 explained in more detail.

[0114] In general, it is stated that the arrangement of the light sources with respect to the adjacently arranged headlight modules 13 can be identical or mirror-symmetrical.

[0115] The Fig. Figure 4a shows a schematic representation of a first part 1b of the headlight arrangement 1, which Fig. 4b an exploded view of it.

[0116] Analogous to the first part 1a of the headlight arrangement, the second headlight modules 14 each comprise a first lens 14a and a second lens 14b, wherein the first lens 14a is a diverging lens and the second lens 14b is a converging lens.

[0117] The first lens 14a is arranged in a second holder 16. The second holder 16 is attached to the first circuit board 1d. A shutter 14c is positioned in front of the second holder 16, and thus in front of the first lens 14a, which can at least partially block the light emitted from the light sources 8a and 10a.

[0118] The aperture 14c in turn includes slot-shaped recesses behind which the light sources 8a, 10 are arranged.

[0119] Downstream of the first lens 14a is a lens holder 14d, which positions lenses 14a and 14b at the correct distance from each other. The lens holder 14d also serves to hold the second lens 14b. The lens holder 14d is attached to both the first circuit board 1c and the second circuit board 1d.

[0120] The electrical components arranged on the second circuit board 1dc form at least parts of the high beam device 2, the low beam device 3, the compensation light device 6, the cornering light device 4 and / or the daytime running light device 5.

[0121] The second high beam modules 8 and the second low beam modules 10 are assigned to the second part 1b of the headlight assembly 1. Accordingly, their light sources 8a, 10 are arranged on the second circuit board 1d.

[0122] However, it is also conceivable that parts of the cornering light device 4 are arranged on the second circuit board 1d. The daytime running light device 5 can be formed by the low beam device 3 or, as in the present embodiment, be an independent device with at least one light source 5a. A combination of the two variants is also possible.

[0123] The Fig. Figure 5 shows a schematic representation of an arrangement of light sources 7a, 8a, 9a, 10a, 11a, 12a of the headlight arrangement 1.

[0124] The first headlight modules 13 and the second headlight modules 14 are represented by rectangles. It is immediately apparent that the arrangement of the light sources 7a, 8a, 9a, 10a, 11a, 12a between the adjacent first headlight modules 13 and second headlight modules 14 is mirror-symmetrical.

[0125] In this embodiment, a first low-beam module 9 comprises six light sources 9a, which are arranged in a line. The first low-beam modules 9 are located closest to a lane of the road.

[0126] Above the first low beam module 9, a first high beam module 7 with three light sources 7a is arranged. The light sources 7a are also arranged in a line.

[0127] At partially the same height, light sources 11a of the first curve light module 11 are provided, wherein the outer light sources 11a are arranged increasing in height towards the outside in order to take into account a tilt when cornering.

[0128] Above each of the first headlight modules 13, a second headlight module 14 is arranged. The second headlight modules 14 comprise the second low beam device 10 and the second high beam device 8. The two light sources 10a of the second low beam device 10 are arranged below the three light sources 8a of the second high beam device 8. Both the light sources 8a and the light sources 10a are arranged in a line.

[0129] In the present embodiment, the cornering light device 4 is arranged only in the area of ​​the first headlight modules 13. However, it is readily conceivable to arrange some or all of the light sources 11a, 12a of the cornering light device 4 in the area of ​​the second headlight modules 14.

[0130] The daytime running light device 5 and its light source 5a are not shown for clarity. These can be arranged in the area of ​​the first headlight modules 13 and / or in the area of ​​the second headlight modules 14.

[0131] Based on the Fig. Section 5 will now explain the operation of a headlight arrangement 1.

[0132] Specifically, it can be provided that in a low-beam mode, all light sources 8a, 9a of the low-beam device 3 are operated at full power. Low beam is emitted.

[0133] In high beam mode, the light sources 8a of the second high beam module 8 are operated at full power, while the light sources 7a of the first high beam device 7 are operated at reduced power. The reduced power can be between 10% and 50%, preferably between 20% and 30%, of the maximum power.

[0134] In addition to the light sources 7a, 8a of the high beam modules 7, 8, the light sources 9a of the first low beam module 9 are also operated at full power. The light sources 10a of the second low beam module 10 are operated at reduced power. The reduced power can be between 10% and 50%, preferably between 20% and 30%, of the maximum power.

[0135] Starting from the low beam mode, compensation for a shortening of the light cone of the headlight assembly 1 can be achieved as follows. If a predefined limit for the vehicle's inclination is exceeded (for example, a pitch angle greater than 4°), the headlight assembly 1 can be operated in a compensation light mode.

[0136] In compensation light mode, the power of the light source 10a of the second low beam module 10 is reduced in order to counteract excessive illumination directly in front of the vehicle and any resulting glare to a driver.

[0137] In addition, the light sources 7a of the first high beam module 7 are operated at full power to compensate for the inclination-related shortening of the light cone of the headlight arrangement 1.

[0138] The light sources 9a of the first low beam module 9 are operated unchanged at maximum power.

[0139] It is also conceivable that in compensation light mode, in addition, some or all of the light sources 11a, 12a of the cornering light device 4 are operated at full and / or reduced power in order to compensate for the inclination-related shortening of the light cone of the headlight arrangement 1.

[0140] Regardless of the operating mode of the headlight assembly 1, the cornering light device 4 can be operated depending on the vehicle's roll angle to achieve better illumination when cornering. The number of lights used and their power output can be changed depending on the roll angle.

[0141] For example, in a left-hand curve with a roll angle of 8°, the two inner light sources 11a of the first cornering light module 11 can be operated at reduced power (e.g., at a power between 30% and 50% of the maximum power). With a larger roll angle (e.g., 12°), the power of the inner light sources 11a can be increased to, for example, 80% of the maximum power.

[0142] If the roll angle increases further, all or some of the outer light sources 11b of the first cornering light module 11 can be switched on at reduced power. This power can then be increased as the roll angle increases.

[0143] It is also conceivable that the power output of the two inner light sources 11a of the first cornering light module 11 is reduced again from a certain roll angle.
