Description

Title of the invention: Lighting device for a motor vehicle.

[0001] The invention relates to the field of lighting. More specifically, the invention relates to a motor vehicle lighting system provided with a light module capable of emitting a pixelated light beam.

[0002] Many countries or regions define regulations, with which motor vehicles must comply in order to be able to circulate on the roads of these countries or regions. In particular, regulations are adopted requiring that the lighting emitted by a projector positioned at the front of a motor vehicle meets specific constraints under precise conditions.

[0003] For example, this is the case of dipped beam lighting which, in most regulations, requires that the latter be achieved by a light beam having a higher cut-off, forming two distinct zones, a first illuminated and a second mostly devoid of lighting.

[0004] Furthermore, there is a need for this same lighting to have an upper cut-off having a very particular shape, called a bathtub, which can also perform a so-called curve-following function.

[0005] In order to address these problems, it is generally known to use light modules comprising a high number of selectively activatable light sources, called elementary light sources, associated with an optical device, to enable the production of pixelated light beams, for example containing at least 500 pixels, each projected pixel being formed by an elementary light beam emitted by one of the elementary light sources.

[0006] Beyond the fact that this type of module makes it possible to carry out advanced lighting functions, for example of the anti-glare road type, ground writing, ground marking or reception scenario, it also makes it possible to define and control the light intensity in precisely delimited zones, while making it possible to selectively activate pixels and thus to be able to form lighting having a predetermined shape.

[0007] However, these pixelated light modules comprise a lighting field limit, so that when the angle of the curve following function approaches the lighting field limit of these light modules, the so-called bathtub shape is no longer achievable by said module, which causes a lack of lighting in this area.

[0008] Furthermore, it is also difficult to be able to combine the complementary recombination of the two modules, in particular due to the difference in pixelation between the two modules.

[0009] The present invention is placed in this context and aims to meet these needs.

[0010] For these purposes, the invention relates to a vehicle lighting device automobile comprising a first light module capable of emitting a first light beam having, when projected onto a screen, an upper cut-off having a first substantially horizontal cut-off comprising a first hollow, a second light module capable of emitting a second pixelated light beam, extending in an emission zone, each pixel being formed by a selectively controllable elementary light beam, the emission zone extending, when the second pixelated light beam is projected onto said screen, at least partially above the upper cut-off of the first light beam and a controller capable of receiving an instruction to emit a regulatory dipped beam type lighting function and arranged to, in response to the reception of said emission instruction,controlling the first light module to emit the first light beam and controlling the second light module to emit only a portion of the second pixelated beam, such that, when projected onto said screen, it has a second substantially horizontal upper cut-off at least partially superimposed on the first cut-off of the first light beam and comprising a second hollow, of dimensions smaller than those of the first hollow, said second hollow being positioned at least partially in the first hollow.

[0011] In the invention, the term “pixelated light beam” means a beam composed of a plurality of pixels arranged in a plurality of rows and / or columns. This beam has a resolution defined in particular as a function of the dimensions of each pixel and the dimension of the emission zone associated with this beam.

[0012] The invention therefore proposes to form a non-dazzling crossing type light beam capable of forming lighting having a so-called bathtub shape, while being able to combine the complementary recombination of the two modules.

[0013] In a particular embodiment, the first light module is capable of emitting a first light beam having, when it is projected onto a screen, an upper cut-off having a first substantially horizontal upper cut-off comprising at least one hollow, said first light beam extending only below said upper cut-off.

[0014] In a particular embodiment, the controller is capable of receiving an instruction to transmit a regulatory dipped-beam type lighting function and is arranged to, in response to receiving said transmission instruction, control the first light module to transmit the first light beam and control the second light module for emitting only a portion of the second pixelated light beam, such that, when projected onto said screen, it has a second substantially horizontal upper cut-off at least partially superimposed on the first cut-off of the first light beam and comprising a second hollow, of dimensions smaller than those of the first hollow, said second hollow being positioned at least partially in the first hollow, said portion of the second pixelated light beam extending only below said second upper cut-off, the portion of the emission zone above said second upper cut-off remaining extinguished.

[0015] Advantageously, the first light module is arranged so that the first cut-off has first and second substantially horizontal portions extending on either side of the first hollow, said first hollow being formed by two inclined portions and a third substantially horizontal portion extending below the first and second horizontal portions and joining the inclined portions.

[0016] It is then understood that the first and second substantially horizontal portions extend respectively to the left and right edges of the emission zone in order to produce the so-called bathtub shape, delimiting a hollow in the form of a relief.

[0017] Preferably, the screen onto which the first and second light beams are projected is provided with an orthonormal reference frame provided with a horizontal axis HH and a vertical axis VV intersecting at an origin, the first light module is arranged so that the first and second portions of the first cut-off are superimposed with the horizontal axis.

[0018] In a preferred embodiment, the first module is also arranged so as to project onto said screen a third substantially horizontal portion extending below the first and second horizontal portions and joining the inclined portions, said third substantially horizontal portion extending vertically in a range going substantially from -0.5° to -1° below the horizontal axis HH, and, horizontally, in a range going substantially from -110 to +11° on either side of the vertical axis VV.

[0019] Preferably, the inclined portions comprise an inclination in a range of 30° to 50°.

[0020] According to the invention, the controller is arranged to, in response to the reception of said emission instruction, control the second light module so that the second cut-off has first and second substantially horizontal portions extending on either side of the second hollow, at least the first portion of the second cut-off being aligned with the first portion of the first cut, and such that said second hollow is formed by two inclined cut lines and a third substantially horizontal portion extending below the first and second horizontal portions of the second cut and joining said inclined portions.

[0021] In a particular embodiment, the controller is arranged to, in response to the reception of said emission instruction, control the second light module so that the second cut-off has first and second substantially horizontal portions extending on either side of the second hollow, at least the first portion of the second cut-off being aligned with the first portion of the first cut-off, and so that said second hollow is formed by two inclined cut-off lines and a third substantially horizontal portion extending below the first and second horizontal portions of the second cut-off and joining said inclined portions, at least one of the two inclined portions of the second cut-off joining the third horizontal portion at the origin, so as to form a hollow in the form of a draft.

[0022] In another embodiment, the controller is arranged to, in response to receiving said emission instruction, control the second light module so that the second cut-off has first and second substantially horizontal portions extending on either side of the second hollow, at least the first portion of the second cut-off being aligned with the first portion of the first cut-off, and so that said second hollow is formed by two inclined cut-off lines and a third substantially horizontal portion extending below the first and second horizontal portions of the second cut-off and joining said inclined portions, the third portion of the second cut-off being aligned with the third portion of the first cut-off.

[0023] In a preferred embodiment, the first module is also arranged so as to project onto said screen a third substantially horizontal portion extending below the first and second horizontal portions and joining the inclined portions, said third substantially horizontal portion extending vertically in a range going substantially from -0.5° to -1° below the horizontal axis HH, and, horizontally, in a range going substantially from -11° to +11° on either side of the vertical axis VV.

[0024] Preferably, the inclined portions comprise an inclination in a range of 30° to 50°.

[0025] In a particular embodiment, the controller is arranged to, in response to the reception of said emission instruction, control the second light module so that the second cut-off has first and second substantially horizontal portions extending on either side of the second hollow, at least the first portion of the second cut being aligned with the first portion of the first cut, and such that said hollow is formed by two inclined cut lines extending below the first and second horizontal portions of the second cut and said inclined cut lines meeting at a determined point.

[0026] According to the invention, the controller is capable of receiving an instruction to emit a lighting function of the curve-following type, and is arranged to, in response to the reception of said emission instruction, control the first light module to emit the first light beam and control the second light module to laterally move the hollow of the second cut-off of the part of the second light beam, the direction of movement of the hollow being a function of the curve-following direction.

[0027] It is understood that the instruction to transmit a curve-following type lighting function is received while the part of the second pixelated light beam is transmitted in response to the instruction to transmit the dipped-beam type lighting function.

[0028] Thus, a lighting device is obtained which can produce a so-called bathtub shape while performing a curve-following function.

[0029] By the terms "laterally moving the hollow of the second cut-off of the part of the second light beam", it is meant that the first and second portions of the second cut-off remain fixed during the lateral movement, only the inclined portions and the third portion move, said third portion remaining at the same height during the movement of the second hollow.

[0030] Advantageously, the controller is arranged to, in response to the instruction to transmit a curve-following type lighting function, control the second light module so as to iteratively light at least one pixel positioned in the hollow on the side opposite to the curve-following direction and concomitantly, capable of turning off a pixel positioned outside the hollow on the side corresponding to the curve-following direction.

[0031] It is then understood that the inclined cuts and the third cut are progressively moved towards the direction of the curve tracking direction by progressively lighting up unlit pixels, in the hollow which moves in the direction of the curve tracking direction, and by progressively lighting up lit pixels in the opposite direction of the curve tracking.

[0032] According to the invention, the controller is capable of receiving an instruction to transmit a non-glare road lighting function, and arranged to, in response to the reception of said transmission instruction, control the first light module to transmit the first light beam and control the second light module. to emit the entire second pixelated light beam in the emission area, except for a dark area positioned above the first upper cutoff.

[0033] Advantageously, the transmission instruction received by the controller also contains predetermined coordinates of an object not to be dazzled, and the dark zone is positioned according to said predetermined coordinates.

[0034] Advantageously, the emission zone being formed by elementary light beams of which at least a part extends, when they are projected onto a screen, below the upper cut-off of the first light beam, so that said emission zone defines a pattern below this upper cut-off is capable of performing a ground writing function for which pixels of the second light beam, located below the upper cut-off of the second light beam and located in a display zone, are controlled to materialize a pictogram or a ground marking, for example by negative or positive contrast, in the overall beam formed by the union of the first and second light beams.

[0035] Advantageously, the first light module comprises at least one first light source and a first optical device arranged to form, from the light rays emitted by said first light source, said first light beam.

[0036] An optical device is understood to mean a device comprising one or more reflectors, or one or more lenses, or a combination of one or more reflectors and one or more lenses.

[0037] Preferably, the first light module comprises at least one selectively controllable light source, said at least one light source forming the first light beam.

[0038] In the invention, all of the light sources are controlled by a controller in accordance with known solutions. For example, each light source can be controlled by a PWM type signal generated by the controller.

[0039] Thus, all of the elementary light beams form a pixelated light beam having predetermined photometric characteristics as a function of said instruction, each pixel thus having a light intensity greater than and / or less than a threshold value defined by the regulations governing the lighting function indicated by the instruction received by the controller.

[0040] According to an exemplary embodiment of the invention, the second light module is arranged so that the second pixelated light beam is a light beam comprising a plurality of pixels, for example 25,000 pixels whose angular resolution is between 0.025° and 0.3°, distributed according to a plurality of lines and columns, for example 80 lines and 320 columns.

[0041] Preferably, the second light module comprises a plurality of selectively controllable elementary light sources, each of the elementary light sources forming one of the elementary light beams.

[0042] In addition, the second light module may also comprise an optical device arranged to emit with all of the selectively controllable elementary light sources said second pixelated light beam.

[0043] A light source is understood to mean any light source possibly associated with an electro-optical element, capable of being activated and selectively controlled to emit an elementary light beam whose light intensity is controllable. It may in particular be a light-emitting semiconductor chip, a light-emitting element of a monolithic pixelated light-emitting diode, a portion of a light converter element excitable by a light source or a light source associated with a liquid crystal or a micromirror.

[0044] In a particular embodiment of the invention, the controller is arranged to selectively control each of the elementary light sources of the second light module according to said instruction, each of the elementary light sources emits an elementary light beam forming one of the pixels of the second pixelated light beam, all of said elementary light beams forming the emission zone.

[0045] Advantageously, the controller is arranged to generate, for each of the elementary light sources and as a function of said instruction, a control signal for said light source determining the light intensity intended to be emitted by said elementary light source, the controller periodically controlling said elementary light source using said control signal.

[0046] In a preferred embodiment, the second light module is capable of emitting said second pixelated light beam in an emission zone, and in which the controller is arranged to control, as a function of said instruction, the second light module to emit a pixelated light beam whose profile, the position in the emission zone is predetermined as a function of said instruction.

[0047] In a preferred embodiment, upon receipt of said instruction, the controller is arranged to selectively control each of the elementary light sources of the second light module, so that at least a portion of the elementary light beams emitted by the elementary light sources form a portion of the upper cutoff of the overall beam formed by the joining of the first and second light beams.

[0048] In a preferred embodiment, all of the first and second modules as well as the controller are arranged in a common projector.

[0049] The present invention is now described using examples which are purely illustrative and in no way limitative of the scope of the invention, and from the appended drawings, drawings in which the various figures represent:

[0054] [Fig.5] represents, schematically and partially, a lighting function performed by the lighting device on a screen, more particularly the road type function;

[0055] In the following description, elements that are identical, by structure or by function, appearing in different figures retain, unless otherwise specified, the same references.

[0056] [Fig.l] shows a partial view of a lighting device 1 of a motor vehicle according to one embodiment of the invention.

[0057] The lighting device 1 comprises, in the example described, a projector 11 in which is arranged a first light module 2 capable of emitting a first light beam F. The first light beam F is a non-pixelated beam extending only below said upper cut-off CS.

[0058] The first light module 2 comprises in particular a first light source 21 and a lens 22 arranged to form, from the light rays emitted by said first light source 21, said first light beam F.

[0059] Still, in [Fig.l], the projector 11 also comprises a second light module 3 capable of emitting a second pixelated light beam HD extending in an emission zone ZE, each pixel being formed by an elementary light beam HD;j which can be selectively controlled.

[0060] The second light module 3 comprises in particular a plurality of elementary light sources 3^ associated with a lens 32. In the example described, the elementary light source 3 hj is a monolithic pixelated light-emitting diode, each of the light-emitting elements of which forms a source elementary light beam 3 lij that can be selectively activated and controlled by a controller 5 to emit light towards the lens 32, which projects an elementary light beam HD,.

[0061] Thus, the second light module 3 comprises a plurality of elementary light sources 31^ that can be selectively controlled, each of the elementary light sources 3Lj forming one of the elementary light beams HD,.

[0062] [Fig. 2] shows a projection of the first F and second HD light beams onto a screen 4 provided with an orthonormal reference frame and positioned 25 meters from the projector 11, respectively fulfilling dipped beam and non-glare road type lighting functions. In this reference frame, the coordinates correspond to horizontal and vertical angles measured from the origin of the reference frame. The positive abscissas correspond to the half-plane located to the right of the vertical axis VV, the negative abscissas correspond to the half-plane located to the left of the vertical axis VV, the positive ordinates correspond to the half-plane located above the horizontal axis HH and the negative ordinates correspond to the half-plane located below the horizontal axis HH.

[0063] The first light beam F having, when projected onto a screen 4, an upper cut-off CS having a first substantially horizontal cut-off CS1 comprising at least one first trough CL

[0064] The emission zone ZE extending when the second pixelated light beam HD is projected onto said screen 4, at least partially above the upper cutoff CS of the first light beam F

[0065] Each elementary light beam HD; j is projected by the lens 32 into a given emission cone, defined by a given emission direction and a given angular aperture. Thus, in the example described, all of the elementary light beams HDij thus form a second pixelated illumination beam HD having 500 pixels distributed over 25 columns and 20 lines, extending in an emission zone ZE defined horizontally by an angular range of 24°, from -15° to +9°, and vertically by a vertical angular range of 6.5°, from -3.5° to +3°, and each pixel of which is formed by one of these elementary light beams HD,. Each elementary light beam HD^ emitted by one of the elementary light sources 3 hj has a horizontal and vertical aperture of less than 1°.

[0066] The first 2 and second light modules 3 are arranged so that the emission zone ZE of the second light beam HD extends below and above the substantially horizontal cut-off CS of the first light beam F.

[0067] The overall beam G, formed by the union of the first light beam F and the second pixelated light beam HD when they are emitted simultaneously, is thus capable of performing several advanced lighting functions, such as different dipped beam lighting functions, non-glare road lighting, a ground writing function, the pixels formed by the elementary light beams HD;j being selectively controlled according to the function that this overall beam G must perform.

[0068] The controller 5 is capable of receiving an instruction to transmit a regulatory dipped-beam type lighting function and is arranged to, in response to receiving said transmission instruction, control the first light module 2 to transmit the first light beam F and control the second light module 3 to transmit only a portion ZI of the second pixelated elementary beam HD, such that, when it is projected onto said screen 4, it has a second substantially horizontal upper cutoff CS2 at least partially superimposed on the first cutoff CS1 of the first light beam and comprising a second hollow C2, of dimensions smaller than those of the first hollow C1, said second hollow C2 being positioned at least partially in the first hollow C1.

[0069] The controller is arranged to selectively control each of the elementary light sources 3 hj of the second light module 3 according to said instruction so that this elementary light source 3 hj emits an elementary light beam HDij forming one of the pixels of the pixelated light beam HD, all of said elementary light beams HD^ forming said part ZI.

[0070] Thus, the second light module 3 is capable of emitting said second pixelated light beam HD in an emission zone ZE, and in which the controller 5 is arranged to control, as a function of said instruction, the second light module 3 to emit a pixelated light beam HD whose profile, the position in the emission zone ZE is predetermined as a function of said instruction.

[0071] Therefore, upon receipt of said instruction, the controller 5 is arranged to selectively control each of the elementary light sources HD, of the second light module 3 so that at least a portion of the elementary light beams HD^ emitted by these elementary light sources 3Cj forms a portion of an upper cutoff CS of the overall beam G formed by the union of the first F and second light beams HD.

[0072] As shown in [Fig.2], some of the elementary light sources 3hj are activated while others are deactivated so that the second light beam HD, formed by the elementary light beams HD; j emitted by the activated sources, has an upper cutoff. A part of this upper cutoff is aligned with the substantially horizontal upper cutoff CS of the first light beam F, the overall light beam G resulting from the superposition of these two F and HD beams thus presenting a higher cut-off of the “low beam” type.

[0073] More precisely, the first light module 2 is arranged so that the first cut-off CS1 has first CSlpi and second CSlp2 substantially horizontal portions extending on either side of the first hollow C1, said first hollow C1 being formed by two inclined portions CSlp; and a third substantially horizontal portion CSlp3 extending below the first CSlpi and second CSlp2 horizontal portions and joining the inclined portions CSlp;.

[0074] Thus, and in order to form a complementarity between the first F and second HD light beams, the first light module 2 is arranged so that the first CSlpi and second CSlp2 portions of the first cutoff CS1 are superimposed with the horizontal axis HH.

[0075] In addition, the controller 5 is arranged to, in response to the reception of said transmission instruction, control the second light module 3 so that the second cutoff CS2 has first CS2pi and second CS2p2 substantially horizontal portions extending on either side of the second hollow C2, at least the first portion of the second cutoff CS2pi being aligned with the first portion of the first cutoff CSlpi.

[0076] The second hollow C2 is then formed by two inclined cut-off lines CS2pi and a third substantially horizontal portion CS2p3 extending below the first CS2pi and second CS2p2 horizontal portions of the second cut CS2 and joining said inclined portions CS2p;.

[0077] The controller 5 is also arranged to, in response to the reception of said transmission instruction, as illustrated in [Fig. 3], control the second light module 3 so that the second cutoff CS2 has first CS2pi and second CS2p2 substantially horizontal portions extending on either side of the second hollow C2, at least the first portion of the second cutoff CS2pi being aligned with the first portion of the first cutoff CSlpi, and so that said hollow C2 is formed by two inclined cutoff lines CS2p; extending below the first CS2pi and second CS2p2 horizontal portions of the second cutoff CS2 and said inclined cutoff lines CS2p; meeting at a determined point.

[0078] As shown in [Fig.4], the controller 5 is able to receive an instruction to emit a lighting function of the curve-following type, and is arranged to, in response to the reception of said emission instruction, control the first light module 2 to emit the first light beam F and control the second light module 3 to laterally move the trough C2 of the second cut-off CS2 of the part ZI of the second light beam HD, the direction of movement of the hollow C2 being a function of the curve following direction, the direction of the curve following direction being illustrated by the arrow shown in [Fig.4].

[0079] Thus, it is understood that the controller 5 is arranged to, in response to the instruction to transmit a curve-following type lighting function, control the second light module 3 so as to iteratively light at least one pixel positioned in the hollow C2 on the side opposite to the curve-following direction and concomitantly, capable of turning off a pixel positioned outside the hollow C2 on the side corresponding to the curve-following direction.

[0080] In other words, the movements of the inclined cuts CS2p; and of the third cut CS2p3 are progressive towards the direction of the curve tracking direction by progressively lighting up unlit pixels, in the hollow C2 which moves in the direction of the curve tracking direction, and by progressively lighting up lit pixels in the opposite direction of the curve tracking.

[0081] The controller 5 is also capable of receiving an instruction to transmit a non-glare road lighting function, as illustrated in [Fig. 5], and arranged to, in response to the reception of said transmission instruction, control the first light module 2 to transmit the first light beam F and control the second light module 3 to transmit the entire second pixelated light beam HD in the transmission zone ZE, with the exception of a dark zone ZS positioned above the first upper cut-off CSL.

[0082] In any event, the invention cannot be limited to the embodiments specifically described in this document, and extends in particular to all equivalent means and to any technically effective combination of these means.

[0083] In particular, other types of light module producing a pixelated light beam than that described may be envisaged, and in particular a light module comprising a combination of a light source and a matrix of micro-mirrors or liquid crystals that can be selectively activated.

[0084] It will also be possible to envisage controlling the lighting system for the emission of other light functions than those which have been described, and in particular motorway type lighting functions or for unfavourable weather conditions, or even light functions in which other types of pictogram or ground marking are provided.
