    FR 3 056 683 - A1 (3g) Light module (1), in particular for lighting and / or signaling for a motor vehicle, comprising:
    - at least two sub-modules (2) each comprising at least two light sources (3) selectively activated to each produce a segment of a partial light beam (5), and
    - a projection optic (4) common to the two sub-modules (2) for projecting said light segments, the sub-modules (2) and the projection optic (4) being arranged to produce a homogeneous segmented beam.

    Light module, in particular for lighting and / or signaling for a motor vehicle
    The field of the present invention is that of light modules for a motor vehicle, and in particular lighting and / or signaling modules.
    A motor vehicle is equipped with headlights, or headlights, intended to illuminate the road in front of the vehicle, especially at night or in bad weather. These headlights can generally be used in two lighting modes: a first "main beam" mode and a second "low beam" mode. The "main beam" mode makes it possible to strongly illuminate the road far in front of the vehicle, at the risk of dazzling the users of the oncoming road. The "low beam" mode provides more limited illumination of the road, but nevertheless offers good visibility, without dazzling other road users. These two lighting modes are complementary. The driver of the vehicle must manually change modes depending on lighting conditions and other road users. Having to manually change modes can be unreliable and dangerous under certain conditions. In addition, the high beam mode provides visibility that is sometimes unsatisfactory for the driver of the vehicle.
    To improve the situation, headlamps with an Adaptive Driving Beam (ADB) function have been proposed. Such an ADB function is intended to automatically detect a road user likely to be dazzled by a light beam emitted in high beam mode by a projector, and to modify the outline of this light beam so create a gray area where the detected user is located. The advantages of the ADB function are multiple: user comfort, better visibility compared to lighting in dipped beam mode, better reliability for changing modes, greatly reduced risk of glare, safer driving.
    In order to perform such an ADB function, a system is known, for example, comprising a plurality of light sources, a primary optical element and an associated projection optical element forming a secondary optic, in which the primary optical element comprises a plurality of light guides having contiguous edges at the output, the outputs of the guides of the primary optical element being positioned in a focal plane object of the secondary optics.
    The light emitted by each light source enters the associated light guide, possibly propagates inside a corrective part common to each guide, then is emitted via the exit face of the corrective part towards the optical element. secondary associated. The light emitted by each light guide exit zone and projected by the secondary optical element forms a vertical light segment at the front of the vehicle. The light sources can be switched on independently of each other, selectively, to obtain the desired lighting.
    Such a lighting system nevertheless has certain drawbacks. In particular, due to the use of several light guides arranged in series to form the primary optical element of such a system, industrialization is made difficult.
    In this context, the present invention aims to propose a light module whose mounting and adjustment are simplified.
    The present invention relates to a light module comprising on the one hand at least two sub-modules each comprising at least two light sources selectively activatable for each to produce a light segment, and on the other hand a projection optics common to the two sub-modules for projecting said light segments, the sub-modules and the projection optics being arranged to produce a homogeneous segmented beam, when all the segments are activated together.
    The light module according to the invention therefore makes it possible to ensure a Matrix Beam function with a single light module, in a compact manner.
    The sub-modules of the light module according to the invention can comprise the same number of light sources, or comprise a different number from. light sources.
    Each sub-module has a separate support for its light sources.
    According to a characteristic of the invention, the light module comprises a plate to support the sub-modules. The sub-modules can in particular be arranged at one end of the plate and the projection optics at one. opposite end of the plate.
    The support for at least one sub-module comprises a front face carrying at least two light sources and a rear face configured to come into contact with a wall of the plate, and in particular against the front face of this wall. In order to ensure this contact, it is possible in particular to provide that the rear face of the support for the sub-module, and / or the front face of the wall of the plate can (at least) include at least one flat portion.
    The support has substantially the shape of a thin plate defined between this front face and the rear face. We can predict that. each sub-module has a support for. this guy.
    Each sub-module is fixed to the plate by a fixing means. Each submodule can be fixed by screwing, gluing, riveting, snap-fastening or any other suitable fixing means.
    In particular, provision can be made for the sub-modules to be fixed by screwing onto the plate, and for this purpose, the plate has at least one orifice, while each support has a bore associated with one of the orifices of the plate. . Each orifice / bore pair is intended to receive a fixing screw, the orifice of the plate or the bore of the support has a wider section than that of the fixing screw. The head of the screw is on the side of the hole which has the widest section. The screwing can therefore be carried out from the front or from the rear depending on which orifice has the widest section.
    The sub-modules are able to be adjusted in rotation and / or in translation, independently of each other, to produce a homogeneous beam. More particularly, the supports of. sources are able to be adjusted in rotation, independently of each other, to obtain this homogeneous beam.
    The support comprises at least one gripping finger. The gripping finger is used to manipulate the sub-module for the. adjust. The manipulation for adjusting the sub-module can be carried out by a human operator or by a machine, automatically or not.
    Each sub-module has a plurality of light sources configured to perform the formation of a segmented partial light beam. The light segments of a partial light beam emitted by a sub-module are joined two by two.
    According to the invention, each of the sub-modules is adjusted so that the light segments corresponding to a sub-module are placed side by side with the light segments corresponding to the neighboring sub-module, or else so that the corresponding light segments to a sub-module are interleaved with the light segments corresponding to another, sub-module. Thus, the light segments can be interlaced with the light segments of a sub-module, neighboring or not, and this interlacing makes it possible to obtain an overlap of light segments, making it possible to selectively ignite bands of the global light beam projected by the light module with a light intensity progressively changing on either side of the strip or strips left extinct.
    The overlap of the light segments can have a width of 1 / n, 1 being the width of the light segment and n being the. number of sub-modules, but other examples of overlap can be envisaged.
    This characteristic makes it possible in particular to obtain, in a single module. simple design with optics. single projection for a plurality of independent and adjustable sub-modules independent of each other, the possibility of having a beam of segmented road beam type.
    The light module can further comprise a control device able to selectively activate or deactivate one or more light segments. The selective activation of one or more light segments can be carried out by the user, or automatically in conjunction with a detection system.
    The light segments are oriented vertically or essentially vertically. By essentially vertical, it is meant that the light segments can have an angle between 0 and 20 ° relative to a vertical axis.
    The module may also include at least one optical element in the vicinity of the light sources and forming a primary optic capable of cooperating with the single projection optic therefore forming a secondary optic, the optical assembly making it possible to produce the light segments. One can in particular provide that the optical element forming the primary optics can be arranged in each sub-module.
    The primary optics are located opposite the sources. They can be formed by microlenses. More particularly, the light module comprises as many microlenses as there are light sources, each light source collaborating with a microlens.
    The light module further comprises at least one projection lens. This projection lens is arranged to project the light segments emitted by the submodules. This projection lens may or may not be curved.
    The light module can include at least one field lens. The field lens may have several portions, each defining an optical aberration correction lens of the projection lens. Among the optical aberrations that the field lens or one of its portions can correct, there are notably but without limitation chromatic aberrations and geometric aberrations. The field lens is positioned on the stage.
    The light module may further comprise at least one separator between the sub-modules. The separator (s) are arranged to avoid stray rays from one submodule to another. The separator (s) are positioned on the plate.
    According to the invention, the light sources collaborate with at least one element among the primary optics, the field lens, the separators and the projection lens to produce a homogeneous segmented beam.
    The invention also relates to a method for mounting a light module as described above in which the position is adjusted of at least one sub-module to obtain a homogeneous segmented beam when all the light sources are switched on. The method includes at least the following steps:
    - the sub-modules are assembled on the board in one. theoretical position, in particular by partial tightening of a fixing means specific to each sub-module,
    - we carry out a first test phase to determine if the segmented beam is homogeneous, and we define a new recalculated position, of at least one sub-module,
    - the fastening means of the at least one sub-module is partially loosened,
    - we rotate the sub-module using the gripping finger, and we perform a second test phase to determine if the segmented beam is homogeneous,
    - the specific fixing means for each sub-module are forcibly tightened to the light module plate.
    A clamp controlled by the photometric bench can grip the support of the submodule to adjust it. The sub-module is entered using the gripping finger specific to each sub-module. More particularly, the gripping can be done by a gripping hole arranged in the gripping finger. The entry hole is arranged to allow entry by the desired adjustment tool. The sub-module is adjusted by a rotation along a vertical axis, along a transverse axis and / or along a plane defined by these two axes.
    In the. process as just presented, one or more process steps can be performed from. automated way.
    Other characteristics, details and advantages of the invention will emerge more clearly on reading the description given below by way of indication in relation to the drawings in which:
    FIG. 1 is a perspective view of a light module according to the invention comprising four sub-modules and their respective plurality of light sources,
    FIG. 2 is a perspective view of a support for light sources constituting a sub-module according to an embodiment of the invention, and
    - Figures 3 and 4 are schematic representations of a global light beam projected by a light module of Figure 1 and a light intensity diagram of this beam when a band forming the beam is extinguished.
    The embodiments which are described hereinafter are in no way limitative: it is possible in particular to imagine variants of the invention comprising only a selection of characteristics described below isolated from the other characteristics described, if this selection of characteristics is sufficient to confer a technical advantage or to differentiate the invention from the state of the prior art.
    In particular, all the variants and all the embodiments described can be combined with one another if nothing is technically opposed to this combination. In such a case, mention would be made in the present description.
    In the figures, the elements common to several figures keep the same reference.
    In the following description, the longitudinal, vertical and transverse names relate to an axis corresponding to the general direction of the rays emitted by the light source. The longitudinal direction corresponds to the general direction of the light rays emitted by the light source. The forward direction designates the direction of emission of light rays by the light source, the rear direction designates the opposite direction. The directions mentioned above are also visible in a trihedron L, V, T shown in the figures.
    The light module 1 according to the invention comprises at least two sub-modules 2, each comprising at least one light source 3 (in particular visible in FIG. 2), as well as a projection optic 4 common to at least two sub- modules 2.
    More particularly, in the example illustrated, the light module 1 according to the invention comprises four sub-modules 2. Two sub-modules 2 comprise five light sources 3, the other two sub-modules 2 comprising seven light sources 3. In the In the example in FIG. 1, there is an alternation between the sub-modules comprising five light sources and those comprising seven light sources.
    The light module 1 further comprises a plate 6 which has a first face 60 on which are arranged the various elements constituting the light module 1. The sub-modules 2 are arranged at a first longitudinal end of the plate 6, while the the projection optic 4 of the light module 1, common to each of the sub-modules, is arranged at an opposite longitudinal end of the plate 6, opposite the sub-modules 2.
    The optics of. projection 4 here consists of a curved projection lens with an input face 41 facing the light sources 3 and the associated sub-modules and an output face 42. The projection optics 4 is common to each sub-module 2 , and it collaborates with the light sources 3 and optical elements associated with the light sources and forming primary optics 22, so as to project in a controlled manner the light rays emitted by the light sources 3 The plate 6 comprises at the first longitudinal end, so to fix the submodules 2, a vertical wall 6l extending the flat base of the plate. The sub-modules 2 are arranged on a front face 62 of. this vertical wall 61, that is to say the face disposed opposite the projection optics 4. The front face 62 of the vertical wall 6l of the plate 6 is planar or substantially planar.
    The plate 6 further comprises a heat sink 7 arranged on a rear face 64 of the vertical wall 61 of the plate 6, said rear face 64 being arranged opposite the front face 62 on which the sub-modules 2 are arranged. The heat sink 7 is arranged to efficiently dissipate the heat generated by the light sources 3 and the electronic components on board the sub-modules 2. In the example of FIG. 1, the heat sink 7 comprises a multitude of fins arranged vertically, but it can advantageously be arranged in a different way.
    In the example shown, the. light module further comprises a field lens 8 and a separator 9, also arranged on the plate 6 of the module between the plurality of sub-modules 2 and the projection optics common to each of the sub-modules, so as to deflect , segment and conform the rays emitted by the light sources on board the sub-modules to direct them appropriately towards the common projection optics at the output of the module.
    The sub-modules 2 each include a support 21, which, as is particularly visible in the figure. 2, has a face, before 211 and a. rear face 212, defining between them the thickness of the plate forming the support 21, as well as a lower part and an upper part defined in the vertical direction as a function of the final arrangement in the vehicle. The light sources 3 of the sub-modules are arranged on the front face 211 of the support 21, and these light sources 3 are aligned transversely in the upper part of the support 21.
    Each sub-module 2 further comprises an optical element 22 disposed opposite the light sources and configured to cooperate with the projection optics common to all of the sub-modules, this common projection optics then forming a secondary optics cooperating with the optical element, forming a. primary optics 22 on board the sub-modules to generate a light beam for lighting and / or signaling. The primary optic 22 is arranged opposite each of the light sources 3, between the light sources 3 and the projection optics 4 forming the secondary optics. The primary optic 22 comprises at least one microlens 23, and preferably a microlens. 23 by light source 3- The microlenses 23 may in particular have a hemispherical, or essentially hemispherical, shape. They are made of a material or an alloy of transparent or translucent material. They are formed and arranged to collaborate with the light sources 3 in order to project in a controlled manner the light rays emitted by the light sources 3 in the direction of the secondary optics, so as to obtain segmented partial light beams 5.
    Projecting the spokes in a controlled manner means that we obtain a beam of rays at the module's output which complies with the specifications and regulations, in terms of shape, color and power. The rays projected in a controlled manner have little or no chromatic aberration.
    In the assembled position of the assembly, the rear face 212 of a support 21 is pressed against the front face 62 of the vertical wall 6l of the plate 6.
    Each light source support 21 3 comprises a threaded bore 215 passing through, arranged essentially in the center of the support 21. More particularly, each threaded bore. 215 is arranged substantially in the center of the support 21, and extends from one face to the other of the support 21.
    Correspondingly, the plate 6 further comprises an orifice, configured on the vertical wall 6l for each, support 21, the orifices being arranged in transverse series.
    By arranged in series, it is understood that the orifices are aligned or essentially aligned along a transverse axis, so as to correspond to the threaded bores 215 of the supports 21 of. light sources 3.
    When the support 21 of. light source 3 is mounted on the plate 6, the threaded bore 215 of the support 21 and the orifice of the plate are aligned, so as to allow passage, to a means of. fixing 26. In the illustrated case, in FIG. 1, this fixing means 26 consists of a tightening screw, the rod diameter of which is substantially equal to that of the threaded bores 215. It is understood that the diameter of the orifices provided in the vertical wall is slightly higher than that of the threaded bores 215 in order to make sure not to block the passage to the fixing screw 26 through the bores. In the example, in Figure 1, all threaded bores 215 have the. same, diameter, but the diameter of one or more threaded bores 215 may be different from the others. Similarly, if all the orifices provided on the vertical wall 61 can have the same diameter, it is conceivable that the diameter of one or more of these orifices is different from the others.
    The fixing screws 26 are inserted through the rear face 64 of the vertical wall 61 of the plate, and they pass through the orifices of the plate to fit into the threaded bores 215 of the supports 21, the screw heads remaining from the sort on the side of the rear face 64 of the vertical wall 61.
    The supports 21 each comprise at least one gripping finger 24, which perpendicularly extends the protruding support from the rear face 212 thereof, being arranged at one end of this support, here in the vicinity of the upper edge. Each gripping finger 24 comprises at least one gripping hole 25, arranged to allow the gripping and the manipulation of the supports 21 by an operator or a machine in order to obtain the desired orientation of each support before their fixing in the light module. . In the example illustrated, the gripping finger has two gripping holes 25, configured to collaborate with any machine tool useful for manufacturing, assembling or adjusting the light module 1.
    As described above, the field lens 8 is arranged on the plate 6, between the sub-modules 2 and the projection optics 4. The field lens 8 is divided into several portions 81 each defining one. lens. correction of optical aberration specifically associated with one of the sub-modules and projecting substantially perpendicularly from a base 83 of the field lens 8, so as to be on the path of the rays emitted by the light sources in the direction of the projection lens 4. Thus, each portion 81 of the field lens 8 collaborates with a sub-module 2 and with ίο the projection optics 4 to project in a controlled manner the light rays emitted by the light sources 3 .
    The light module 1 according to the invention also comprises a separator 9 configured to compartmentalize all of the rays emitted by the light sources into a plurality of successive bands, and in particular to intercept the stray rays emitted by the sub-modules 2. The rays parasitic rays are the light rays emitted by the light sources 3 of a sub-module 2, the trajectory of which deviates significantly from the general axis of the light rays, these parasitic rays being able to interfere with the optimal functioning of the neighboring sub-modules 2. The separator 9 is formed or covered with an opaque material, capable of absorbing light rays.
    The separator 9 is also arranged on the plate 6, between the sub-modules 2 and the field lens 8. The separator 9 comprises longitudinal walls 91 arranged in transverse series and which extend respectively between the portions 8l of the lens , of field 8 and between the sub-modules 2. The separator thus makes it possible to define light distribution conduits 92, from a sub-module 2 disposed at a longitudinal end of the separator to a field lens disposed at the opposite longitudinal end. The parasitic rays emitted by the light sources 3 of a sub-module 2 are absorbed by the longitudinal walls 91 of the distribution conduits 92, and the majority of the light rays emitted by each sub-module 2 is directed towards the corresponding portion 8l of the field lens then projected in a controlled manner towards the projection optics 4, common to each distribution conduit 92.
    This results in obtaining a segmented light beam at the output of the light module as it is notably visible in FIG. 3. Each sub-module 2 (designated 2A to 2D in FIG. 1) thus participates in the creation of '' a partial light beam (designated 5A to 5D in Figure 3) projected at the output of the common projection lens, and each partial light beam is segmented due to the arrangement in series of a plurality of light sources in each sub -module.
    In the example illustrated, two non-consecutive sub-modules 2A and 2C comprise seven light sources and seven associated microlenses and the partial light beams SA and 5C which they participate in projecting comprise seven segments, while the other two sub-modules 2B and 2D, therefore also non-consecutive also, comprise five light sources and five associated microlenses so that the partial light beams SB and 5D which they participate in projecting comprise five segments.
    The light segments of a partial light beam are joined two by two, and these different partial light beams 5A, ..., 5D projected at the exit of the optics of. common projection are interlaced, so that in the global light beam 5, formed by the addition of the partial beams, an illumination strip 51 can be formed, in particular at the center of the global beam, by the superposition of a plurality of segments light respectively belonging to one of the partial light beams. In other words, the light segments of one submodule are interlaced with the light segments of another submodule.
    An illumination strip 51 can thus be illuminated or not as a function of the lighting or not of such or such segment, and the light intensity of this lighting strip can be varied as a function of the number of. illuminated light segments that compose it.
    In the example illustrated in FIG. 3, each strip 51 thus consists of a part of four, different light segments, each coming from a partial light beam 5 produced by the cooperation of a specific sub-module and of common projection optics and separate sub-module.
    In normal operation, when the vehicle is the only one traveling, all of the light sources 3 are illuminated. The light module 1 thus illuminates the route taken by the vehicle to the maximum of its capacities. In the event of the occurrence of another user, whether this user is a pedestrian, a vehicle arriving in the opposite direction or a vehicle preceding that of the user, it is possible to selectively deactivate certain light sources 3 so as to no longer project certain light segments of the partial light beam. This has the effect of deactivating certain 5L bands, in particular those which have been identified as, those participating in the lighting, of the user detected on the road scene, and of modifying the lighting contour of the global light beam projected by the vehicle of the user, so as not to dazzle other users.
    By way of nonlimiting example, a vehicle arriving in the opposite direction can be detected in a straight line, substantially in the center of the light beam, and it is therefore appropriate that the light strip 51 illustrated in FIG. 3 be turned off. Each of the light sources 3 corresponding, in a sub-module, light 2, to the lighting of this lighting strip is then switched off. In the example illustrated, the fourth source, the source of the first sub-module 2A, generator of the first partial light beam SA, is thus extinguished, and the second source of the second sub-module 2B, generator of the second partial light beam SB is simultaneously extinguished. , the third source of the third sub-module 2C, generator of the third partial light beam 5C and the second source of the fourth 2D sub-module, generator of the fourth partial light beam 5D.
    The light intensity profile of the resulting overall light beam has been illustrated in FIG. 4. It can be observed that the lighting strip 51 in which the third vehicle has been detected is completely extinguished, and that the lighting strips arranged in the vicinity thereof have a light intensity progressively increasing as the away from the switched off light strip. This avoids too strong contrasts between the extinct strip and the rest of the light beam which could be detrimental to the driver's vision.
    In the example illustrated, it is understood that the light strip 51 'directly in the vicinity of the extinguished lighting strip 51 is formed by the same second source of the second sub-module 2B, third source of the third sub-module 2C, and second source of the fourth 2D sub-module, which are therefore extinguished, as well as by the third source of the first sub-module 2A, generator of the first partial light beam 5A, which it remained on, selectively with respect to the fourth source of the first sub module 2A. As a result, the light strip 51 ’directly in the vicinity of the extinguished lighting strip 51 is turned on with a light intensity corresponding substantially to a quarter of the maximum light intensity.
    Likewise, the second light strip 51 ”disposed directly in the vicinity of the light strip 51 ′ partially lit is formed by the same second source of the second sub-module 2B and third source of the third sub-module 2C as the light strip off , as well as by the third source of the first sub-module 2A, generator of the first partial light beam 5A, and the first source of the fourth 2D sub-module which they have remained on, selectively with respect to the fourth source of the first sub-module 2A and the second source of the fourth 2D sub-module. As a result, this second 51 ”light strip is lit with a light intensity corresponding substantially to half of the maximum light intensity.
    This progressive evolution of the light intensity of the lighting bands is made possible by the segmentation of each of the partial light beams 5A, ..., 5D, and the selective activation of the light sources generating these partial light beams, by the superposition of the set of partial light beams into a homogeneous global light beam when all the segments are lit together, and by the angular offset of each partial light beam with respect to each other so that the segments of a sub -module are interleaved with the segments of the neighboring submodule.
    It is understood that the segmentation of each of the partial light beams is in particular made possible by the presence of a plurality of light sources in each sub-module, these light sources being able to be activated independently of one another.
    The superimposition of all of the partial light beams into a homogeneous overall light beam is made possible by the presence of a projection optic common to each of the sub-modules, the projection optics being configured to present on the path of the rays emitted by each sub-module a section adapted to correct the rays to obtain a homogeneous beam at the output. As it has been described, it may be advantageous to provide between the sub-modules and the common projection optics optical elements participating in correctly compartmentalizing the rays in order to avoid parasitic rays which may interfere with the homogeneous nature of the light beam. overall projected at the output of the light module.
    And the angular offset of each partial light beam relative to one another is made possible by a specific angular positioning of each of the submodules 2 relative to the plate 6 and in particular relative to the vertical wall 6l. We will describe below a method of adjusting the position of the sub-modules in the light module. We will aim in particular to correctly position each sub-module with respect to the others so that the overlapping of the light segments of a sub-module by those of a neighboring sub-module has a desired width, the width being equal to 1 / n, with 1 the width of the light segment and n the number of sub-modules.
    In the example illustrated where one aims to extinguish in the global light beam one or more successive light bands so as not to dazzle a third vehicle, it is understood that we can change the position of the light band or bands that l 'we wish to switch off: as the distance between the vehicles decreases, the vehicle arriving opposite will move relatively towards the outside of the global light beam projected by the. user vehicle. We then wish to successively turn off the first light strip 51 ’then the second light strip 51”, and we switch off for this purpose each of the light sources participating in the formation of this light strip, leaving the other light sources on.
    The example here described of switching on and off the light sources, in order to generate a dark strip which does not dazzle a vehicle arriving in the opposite direction, is in no way limiting, and the module according to the invention is suitable for being used effectively in many situations.
    We have mentioned above the advantage according to the invention of being able to adjust the angular position of the sub-modules 2 with respect to each other, and a description will now be given of an example of mounting and adjustment of the light module 1.
    On one side, the sub-modules 2 are assembled, by assembling the elements of the sub-modules 2 together, in particular by fixing the light sources 3 on the support 21 in a transverse series, then by fixing the optical element 22 on the support 21, of. so as to arrange the microlenses 23 opposite the light sources.
    On the other hand, all of the elements of the light module 1 are positioned on the plate 6, placing from one longitudinal end to the other of. the plate, in particular the projection lens 4, the camp lens 8 and the separators 9.
    Each of the sub-modules 2 is then placed on the vertical wall 6l of the plate 6, by fixing these sub-modules independently of each other with a fixing screw 26 specific to each sub-module. As has been described above, a sub-module is brought against the vertical wall, in particular by manipulating the sub-module by means of the gripping finger 24, by pressing the rear face 212 of a support 21 against the front face 62 of the vertical wall 61, and by making the threaded bore 215 of the support 21 correspond with the corresponding orifice made in the vertical wall 6l. One can in particular provide indexing means to facilitate the positioning of the support 21 and the alignment of the orifices.
    line, each time, sub-module mounted on the plate 6, a test is carried out on a photometric bench to verify that the segments are correctly superimposed with respect to each other.
    If the position of one of the sub-modules must be modified according to the results of this test, a partial unscrewing of the fixing means 26 is carried out to allow mobility of the sub-module relative to the vertical wall of the plate. , and a robot is piloted to manipulate the rotating sub-module, around an axis substantially parallel to the vertical wall 61, by means of the gripping finger. Alternatively, the robot can be controlled to manipulate the sub-modules 2 according to translations, for example along the directions T and V. As soon as the recalculated position for each sub-module is obtained, the fixing screw is again tightened 26 for pressing the sub-module support 21 against the vertical wall 6l of the plate 6, maintaining the recalculated position of the sub-module by means of the gripping finger. And this sequence of operations is repeated for each of the sub-modules whose position is to be adjusted.
    It should be noted that additional steps may be provided, in particular a step of adjusting the projection optics 4, of the lens. field 8 or of the separator 9, to improve the projection of the overall light beam produced by the light module 1 according to the invention.
    The invention described above makes it possible in particular to obtain a matrix beam, of the Matrix Beam type, with a light module 1 embedding on a stage a projection optics common to a plurality of sub-modules, easy to mount independently of the plate, and easy to adjust.
