Description

Field of the Invention

[0001] The present invention relates to a lighting device for a motor vehicle according to the preamble of claim 1, in particular a headlamp for a motor vehicle. Background Art

[0002] A lighting device having a matrix arrangement of light-emitting diodes (LEDs) is used to generate pixels of a light distribution that is generated in the external space of a motor vehicle during operation of the lighting device. The lighting device generally has a uniform pixel size and has a symmetrical division of individual blocks, and the individual blocks are connected to corresponding drive components. A headlamp that is to generate a dipped beam portion and a main beam portion with fan-shaped rows and bright-dark boundaries in a matrix light distribution requires a corresponding light source that has a specific aspect ratio of the generated light distribution to meet regulatory requirements and / or customer needs. Generally, the required aspect ratio becomes possible by using a large number of pixels or by increasing the pixels. Here, using a large number of pixels results in high costs due to the corresponding electronic components, while increasing the pixels results in a loss of resolution in the dipped beam and main beam.

[0003] A lighting device of the type described at the beginning is known from DE102019132236A1. The lighting device described therein is configured as a high-resolution headlamp. The headlamp includes a light source configured as a solid-state LED array having a plurality of light-emitting diodes (LEDs), the light-emitting surfaces of which are used to generate pixels of a light distribution that is generated in the external space of a motor vehicle during operation of the lighting device. The light-emitting surfaces are arranged in a matrix in a first direction and a second direction perpendicular to the first direction. In the light distribution generated in the external space of the motor vehicle, the first direction corresponds to the horizontal direction, and in the light distribution generated in the external space of the motor vehicle, the second direction corresponds to the vertical direction, and the light-emitting surfaces of at least a plurality of the light-emitting diodes are each larger in the first direction than in the second direction.

[0004] Making full use of different pixel sizes and geometries, such as squares and rectangles, enables the desired design to be achieved with a reduced number of pixels and still achieve the required aspect ratio. However, this may make the control of the individual light-emitting diodes more complex. Summary of the Invention

[0005] The problem underlying the present invention is to provide a lighting device of the type described at the beginning that enables the light source to be driven with a smaller number of electronic components and / or is flexibly usable.

[0006] According to the present invention, this is achieved by means of a lighting device of the type described at the beginning with the features of claim 1. The dependent claims relate to preferred embodiments of the present invention.

[0007] According to claim 1, the lighting device is arranged such that the at least one first light-emitting diode operates with a first operating current in the switched-on state and the at least one second light-emitting diode operates with a second operating current in the switched-on state, wherein the first operating current is less than the second operating current. Thus, the lighting device can operate different light-emitting diodes with different operating currents, which have different light-emitting surface sizes or different pixel sizes from one another. Compared to the light-emitting diode with the second light-emitting surface having a large pixel size, the first light-emitting diode with the first light-emitting surface having a small pixel size thus operates with a smaller drive current. This can in particular result in cost savings with regard to the control electronics, since fewer drive components may be required and the space requirement on a circuit board equipped with the light source and the drive components can be reduced. Nevertheless, the aspect ratio for achieving the low beam and high beam requirements can still be adhered to.

[0008] It may be provided that the first light-emitting surface and the second light-emitting surface differ in their geometry, in particular, the second light-emitting surface extends more in a second direction compared to the first light-emitting surface. It may also be provided that the light source has at least one third light-emitting diode with a third light-emitting surface, the first light-emitting surface being smaller than the third light-emitting surface, and the light source is arranged such that the at least one third light-emitting diode operates with a third operating current in the switched-on state, the third operating current being greater than the first operating current. Here, the third operating current can quite well be as large as the second operating current. It may also be provided that the third light-emitting surface differs in its geometry from the first light-emitting surface and the second light-emitting surface, in particular, the third light-emitting surface extends more in a first direction compared to the first light-emitting surface and the second light-emitting surface, and the second light-emitting surface extends more in a second direction compared to the third light-emitting surface. By using different pixel sizes and geometries, a high resolution can be maintained compared to a highly pixelated system.

[0009] There is a feasible solution that the lighting device is arranged such that each of the light-emitting diodes can be controlled individually or in groups in order to switch a single light-emitting diode or a group of light-emitting diodes or all of the light-emitting diodes from the off state to the on state or from the on state to the off state, in particular, a single light-emitting diode and / or a group of light-emitting diodes can be controlled independently of one another.

[0010] Here, the lighting device can include at least one drive component, in particular a plurality of drive components, which are arranged to control a plurality of the light-emitting diodes.

[0011] It can be stipulated that the light source is arranged for: being connected to at least one first driving component, in particular to a plurality of first driving components, in a first configuration of the lighting device to control the light-emitting diodes, and being connected to at least one second driving component, in particular to a plurality of second driving components, in a second configuration of the lighting device to control the light-emitting diodes, wherein the first driving component and the second driving component are different in terms of the maximum number of light-emitting diodes that can be independently controlled by the respective driving components. For example, the first driving components can independently control at most 16 light-emitting diodes, and for example, the second driving components can independently control at most 12 light-emitting diodes. Thereby, the light source of the lighting device can be flexibly combined with different types of driving components, so that the lighting device can be easily integrated into different types of motor vehicles. Here, the use of the first and second driving components is generally not feasible in the same configuration. Instead, either a configuration in which only the first type of driving component is used is selected, or a configuration in which only the second type of driving component is used is selected.

[0012] There is a feasible solution as follows: The light-emitting diodes are arranged in at least two rows in the light source, the rows extending in a first direction and arranged side by side in a second direction. In particular, the light source has 48 light-emitting diodes. Here it can be stipulated that at least one row of light-emitting diodes has at least one center tap, in particular a plurality of center taps, for the anodes and cathodes of the light-emitting diodes, such that partial rows of light-emitting diodes are arranged on the left and right of the at least one center tap in the first direction, and in each of the partial rows, the light-emitting diodes can operate with different operating currents from each other. Here, the at least one center tap, in particular the plurality of center taps, can be arranged in the at least one row of light-emitting diodes such that the total number of light-emitting diodes formed by the at least one center tap is divisible by 4. By arranging the center taps appropriately, the light source can be efficiently and flexibly integrated into different wiring environments.

[0013] There is a feasible solution as follows: The lighting device includes a connection plug for connecting to at least one control device channel, in particular to a plurality of control device channels, the at least one control device channel starting from a control device which is part of the lighting device or part of a motor vehicle. Here, the lighting device can include a circuit board, and the light source, the at least one driving component, and the connection plug are arranged on the circuit board.

[0014] It can be stipulated that in the at least one control device channel, in particular in each of the plurality of control device channels, a plurality of signal lines for controlling a plurality of light-emitting diodes and at least one line for supplying power to the plurality of light-emitting diodes are provided. Herein, the light source can be arranged to be connected to a plurality of first control device channels in a first configuration of the lighting device for controlling the light-emitting diodes and for supplying power to the light-emitting diodes, and to be connected to a plurality of second control device channels in a second configuration of the lighting device for controlling the light-emitting diodes and for supplying power to the light-emitting diodes, wherein the plurality of first control device channels and the plurality of second control device channels are different in terms of the distribution of the signal lines and the power supply lines to each control device channel. Thereby, the light source can be connected to different types of control devices efficiently and flexibly.

[0015] There is a feasible solution that the light source is configured as a solid-state LED array or includes a solid-state LED array. Description of the Drawings

[0022] In the figures, the same and functionally identical components are provided with the same reference numerals. Herein, a Cartesian coordinate system is shown in Figure 1 .

[0023] The lighting device shown in the figures is configured as a headlight. The lighting device includes a light source 1, which is configured as a solid-state LED array. The light source 1 has 48 light-emitting diodes (LEDs) 2a, 2b, 2c, which are used to specifically generate the pixels of the light distribution generated in the external space of the motor vehicle during the operation of the headlight, wherein this light distribution particularly includes a dipped beam portion and a high beam portion.

[0024] Each of the light-emitting diodes 2a, 2b, 2c has a light-emitting surface L1 - L 48 , wherein the respective light-emitting surfaces L1 - L of the light-emitting diodes 2a, 2b, 2c 48 are partially different in size and partially have different geometries. The light-emitting surfaces L1 - L of the light-emitting diodes 2a, 2b, 2c 48 are arranged one above the other in two rows in Figure 1 . These rows extend in a first direction X and are arranged side by side in a second direction Y perpendicular to the first direction. In the light distribution generated in the external space of the motor vehicle, the first direction X corresponds to the horizontal direction, and in the light distribution generated in the external space of the motor vehicle, the second direction Y corresponds to the vertical direction.

[0025] The light source has 24 first light-emitting diodes 2a, 20 second light-emitting diodes 2b, and 4 third light-emitting diodes 2c. The light-emitting surfaces L1 - L of the first light-emitting diodes 2a 24 are arranged in the lower row in Figure 1 and have a substantially square geometry. The light-emitting surfaces L of the second light-emitting diodes 2b 27 - L 46 are arranged in the upper row in Figure 1 and have a rectangular geometry, wherein the extension dimension of the light-emitting surfaces L 27 - L 46 in the second direction Y is greater than the extension dimension in the first direction X. The light-emitting surfaces L of the third light-emitting diodes 2c 25 、L 26 、L 47 、L 48 are respectively arranged on the outside in the upper row in Figure 1 and in the lower row in Figure 1 . They also have a rectangular geometry, wherein the extension dimension of the light-emitting surfaces L 25 、L 26 、L 47 、L 48 in the first direction X is greater than the extension dimension in the second direction Y.

[0026] The lighting device further comprises a plurality of drive assemblies 3a, 3b, 3c and a connection plug 4 for connection to control device channels 5a, 5b, 5c, 5d, which lead from a control device not shown. The control device can be part of the lighting device or part of a motor vehicle. Here, in each of the control device channels 5a, 5b, 5c, 5d, a plurality of signal lines 6 for actuating a plurality of the light-emitting diodes and at least one line 7 for supplying power to a plurality of the light-emitting diodes can be provided. The connection plug 4 can here not only have connection means for the four control device channels 5a, 5b, 5c, 5d, but can also quite generally have connection means for other lines, which for example enable voltage supply or connection to a bus system etc.

[0027] The lighting device further comprises a circuit board not shown, on which the light source 1, the drive assemblies 3a, 3b, 3c and the connection plug 4 are arranged. Figure 2 Schematically illustrates the wiring connection of the light source 1 and the drive assemblies 3a, 3b, 3c to the signal lines 6 leading from the control device channels 5a, 5b, 5c, 5d and the lines 7 for supplying power to the light-emitting diodes 2a, 2b, 2c.

[0028] The signal lines 6 extend in series from the connection plug 4 to the drive assemblies 3a, 3b, 3c. From each of the drive assemblies 3a, 3b, 3c, a respective actuating line 8a, 8b, 8c extends to a group of light-emitting diodes 2a, 2b, 2c in order to actuate the group of light-emitting diodes in correspondence with the signals from the signal lines 6. The lines 7 for supplying power extend directly from the connection plug 4 to the light source 1 in order to supply power to a group of light-emitting diodes 2a, 2b, 2c appropriately. Here, only one of the respective lines 7 is drawn in Figure 2 . It is clear in Figures 3 to 5 that more than one line 7 is provided.

[0029] Figure 3 shows a first configuration of the lighting device. Here, the power supply via different lines 7 or different control device channels 5a, 5b, 5c, 5d is represented by regions 9a, 9b, 9c, 9d with different hatching.

[0030] Figure 3 In the upper right part in 12 on the light exit surface L1 - L 12 the region 9a indicates that the first light-emitting diode 2a associated with the light exit surface L1 - L

[0031] Figure 3 In the upper left part in 13- L 24 The area 9b on it indicates that the first light-emitting diode 2a arranged in correspondence with the light-emitting surface L 13 - L 24 is powered by the second control device channel 5b. Since the light-emitting surface L1–L of the first light-emitting diode 2a 24 has a relatively small size, the operating current can be smaller than the operating currents in the second and third light-emitting diodes 2b, 2c.

[0032] Figure 3 The lower right part in the middle is arranged on the light-emitting surface L 37 - L 48 The area 9c on it indicates that the second and third light-emitting diodes 2b, 2c arranged in correspondence with the light-emitting surface L 37 - L 48 are powered by the third control device channel 5c.

[0033] Figure 3 The lower left part is arranged on the light-emitting surface L 25 - L 36 The area 9d on it indicates that the second and third light-emitting diodes 2b, 2c arranged in correspondence with the light-emitting surface L 25 - L 36 are powered by the fourth control device channel 5d. Since the light-emitting surfaces L of the second and third light-emitting diodes 2b, 2c 25 – L 48 have a relatively large size, the operating current must be greater than the operating current in the first light-emitting diode 2a.

[0034] Here, a plurality of intermediate taps 10 for the anodes and cathodes of the light-emitting diodes 2a, 2b, 2c are arranged in the rows of the light-emitting diodes 2a, 2b, 2c, such that in the first direction X, partial rows of the light-emitting diodes 2a, 2b, 2c are arranged on the left and right of each intermediate tap 10, and in the partial rows, the light-emitting diodes 2a, 2b, 2c can operate with different operating currents from each other. Here, the intermediate taps 10 are arranged in the rows of the light-emitting diodes such that the total number of the light-emitting diodes 2a, 2b, 2c in the partial rows formed by the intermediate taps 10 is divisible by 4.

[0035] Figure 3 It also shows in the middle that the first light-emitting diode 2a arranged in correspondence with the light-emitting surfaces L1 - L8 and the second and third light-emitting diodes 2b, 2c arranged in correspondence with the light-emitting surface L 41 -L 48 are controlled by the driving assembly 3a. In addition, the first light-emitting diode 2a arranged in correspondence with the light-emitting surfaces L9 - L 24 is controlled by the driving assembly 3b. In addition, the light-emitting surface L25 - L 40 The second and third light-emitting diodes 2b and 2c arranged in a matching manner are controlled by the driving component 3c. Therefore, each driving component 3a, 3b, 3c controls 16 light-emitting diodes 2a, 2b, 2c.

[0036] In Figure 4 the second configuration shown, the power supply is carried out as in the first configuration. In Figure 4 the second configuration shown, the control of the light-emitting diodes 2a, 2b, 2c is different from that in the first configuration.

[0037] Figure 4 It is shown that the first light-emitting diode 2a arranged in a matching manner with the light-emitting surfaces L1 - L4 and the second and third light-emitting diodes 2b, 2c arranged in a matching manner with the light-emitting surface L 37 -L 48 are controlled by the driving component 3a. In addition, the first light-emitting diode 2a arranged in a matching manner with the light-emitting surfaces L5 - L 20 is controlled by the driving component 3b. In addition, the first light-emitting diode 2a arranged in a matching manner with the light-emitting surface L 21 - L 24 and the second and third light-emitting diodes 2b, 2c arranged in a matching manner with the light-emitting surface L 25 - L 36 are controlled by the driving component 3c.

[0038] Therefore, in the second configuration, each driving component 3a, 3b, 3c also controls 16 light-emitting diodes 2a, 2b, 2c. The driving components 3a, 3b, 3c are the first driving components or the driving components of the first type, and they can control at most 16 light-emitting diodes 2a, 2b, 2c independently of each other.

[0039] In Figure 5 the third configuration shown, the power supply is carried out as in the first and second configurations. In Figure 5 the third configuration shown, the control of the light-emitting diodes 2a, 2b, 2c is different from that in the first and second configurations. In the third configuration, the second driving components 11a, 11b, 11c, 11d or the driving components of the second type 11a, 11b, 11c, 11d are used, and they can control at most 12 light-emitting diodes 2a, 2b, 2c independently of each other. Therefore, in order to control 48 light-emitting diodes 2a, 2b, 2c, four second driving components 11a, 11b, 11c, 11d are required.

[0040] Figure 5 It is shown that the first light-emitting diode 2a arranged in a matching manner with the light-emitting surfaces L1 - L 12 is controlled by the driving component 11a. In addition, the light-emitting surface L 13- L 24 The first light-emitting diode 2a arranged in a matching manner is controlled by the driving component 11b. In addition, with the light-emitting surface L 25 - L 36 The second and third light-emitting diodes 2b, 2c arranged in a matching manner are controlled by the driving component 11c. In addition, with the light-emitting surface L 37 - L 48 The second and third light-emitting diodes 2b, 2c arranged in a matching manner are controlled by the driving component 11d. Therefore, each of the driving components 11a, 11b, 11c, 11d controls 12 light-emitting diodes 2a, 2b, 2c.
