    [0001] The invention relates to the field of lighting projectors, especially for a motor vehicle. BACKGROUND OF THE INVENTION The invention relates to a strip lighting projector comprising a lighting module according to the invention. A motor vehicle is equipped with headlamps, or headlights, intended to illuminate the road in front of the vehicle, at night or in the case of reduced luminosity. These projectors can generally be used in two lighting modes: a first mode "high beam" and a second mode "low beam". The "high beam" mode provides strong illumination of the road far ahead of the vehicle. The "low beam" mode provides more limited illumination of the road, but still offers good visibility without dazzling other road users. These two lighting modes are complementary. The driver of the vehicle must manually change the mode according to the circumstances, at the risk of dazzle inadvertently another user of the road. In practice, changing the lighting mode manually can be unreliable and sometimes dangerous. In addition, the dipped beam mode provides visibility sometimes unsatisfactory for the driver of the vehicle. To improve the situation, projectors equipped with Adaptive Driving Beam, ADB, adaptive lighting have been proposed. Such an ADB function is intended to automatically detect a user of the road likely to be dazzled by a beam of light emitted in headlight mode by a projector, and to modify the outline of this beam of light in a manner to create a shadow zone at the location of the detected user. The advantages of the ADB function are multiple: comfort of use, better visibility compared to a lighting in dipped beam mode, better reliability for the change of mode, risk of dazzling greatly reduced, driving safer. EP2743567A1 discloses a motor vehicle headlamp with modules generating strip lighting through a projection lens. Each module comprises a series of light guides for shaping radiation from light-emitting diodes. With such a projector, it is possible to illuminate an environment using light bands whose positions are controlled. However, the integration of a projector in a given vehicle and the style imposed by the manufacturer of the vehicle impose a specific shape to the projection lens. Known band projectors use complex optical systems having projection and correction lenses with precise curvatures. In general, the geometry of a projection lens is optimized over its entire width in order to optimize the geometry and location of the light bands projected by a plurality of light sources that use the lens in parallel. In order to minimize the optical aberrations and thus optimize the sharpness and the shape of the light bands, it is usual to provide a projection lens (in the case where it is convergent) having a curved convexity on the exit face than on the input side (vertical and horizontal). For each different light source arrangement and for each style imposed by the manufacturer of the vehicle equipped with the projector in question, a custom optical system must be designed and implemented, which leads to significant development time and costs. These costs are however common since the car manufacturers wish to stand out more and more by an optical signature. The optical signature changes in principle for each vehicle model and requires a particular arrangement of light sources, and therefore a dedicated complex optical system in order to implement an ADB type functionality.
    [0002] The invention aims to overcome at least one of the problems posed by the prior art. More specifically, the invention aims to provide a lighting module, one or more instances can be used to assemble a variety of projectors for motor vehicles having different optical signatures and being able to implement an ADB type of functionality.
    [0003] The invention relates to a lighting module for a strip lighting device of a motor vehicle lighting projector. The module comprises: at least one primary optical element provided with a luminous pixel forming structure intended to cooperate with at least one source and an output corrector diopter, each primary optical element defining an optical axis ; A projection lens The module is configured to project light entering the primary optical element (s) and exiting through the projection lens in the form of a light pixel, such as a light strip. The module is remarkable in that in the normal direction of mounting the output diopter of the projection lens has a toric shape. Preferably, in a horizontal plane in the normal direction of assembly, the exit diopter of the projection lens may have a convex curvature of radius of curvature R given by the formula: a - R = (sin (-) 1) 2 2 in which - L is the width of the projection lens viewed from the front; Where λ is the angular width in degrees of a light band projected by the module, and k and N are positive integers. In a horizontal plane in the normal direction of assembly the output diopter of the projection lens may preferably have a convex curvature of radius 20 of curvature R greater than 200 mm and preferably between 400 and 1200 mm. Preferably, in a horizontal plane in the normal direction of assembly, the projection lens may comprise an input diopter with at least one portion having a convex profile, the convexity or convexities being generally aligned at the positions of the optical axes of the primary optical elements of the module. Preferably, the pixel forming structures may comprise at least one light guide and / or pads or microlenses. Preferably, the at least one light source may comprise at least one light emitting diode, LED, and / or a laser diode.
    [0004] The module may preferably comprise lateral positioning means intended to horizontally juxtapose two identical modules in the normal direction of assembly, so that the output dioptres of the modules form a continuous surface. Preferably, the positioning means may comprise at least one notch formed in a first lateral face of the projection lens, and at least one protrusion formed in the second lateral face, so that the at least one protrusion of a first module can engage in the at least one corresponding notch of an identical module juxtaposed horizontally in the normal direction of assembly. Alternatively, the module may comprise support means on which the one or more light sources and the projection lens are arranged, the support means comprising the alignment means. The support means, such as a generally flat plate, then comprises lateral means which serve to arrange a first module laterally in the normal direction of assembly next to a second identical module, so that the projection lenses both modules form a continuous face. Advantageously, the module may comprise a heat sink on which the light source (s) and the projection lens are arranged, the heat sink comprising the alignment means. Preferably, in the normal mounting direction, the lateral extent of a module may be increasing in the direction of the light emitted by the module. Alternatively, in the normal mounting direction, the lateral extent of a module may be decreasing in the direction of the light emitted by the module. The smallest lateral extent of the module in the normal mounting direction is preferably 5 to 50% smaller than the largest lateral extent of the module in the normal mounting direction. The invention also relates to an assembly comprising a plurality of identical lighting modules according to the invention. The assembly is remarkable in that the lighting modules are assembled in horizontal juxtaposition in the normal direction of assembly, so that the respective projection lenses form a continuous surface of the assembly. The invention also relates to a strip lighting device for a motor vehicle lighting projector comprising at least two lighting modules according to the invention or at least one assembly according to the invention or at least one module of the invention. lighting according to the invention and at least one assembly according to the invention. The invention proposes a lighting module that makes it possible to project at least one light band. A plurality of identical modules may be arranged side by side in the normal direction of mounting within a motor vehicle headlight to provide a strip lighting device. Due to the specific curvature of the surface of the projection lens of each of the identical modules, this arrangement results in a continuous surface with constant curvature at the level of the projection lenses thus aligned. Although each module can be powered and controlled individually and independently of each of the other modules of such an assembly, the assembly itself gives the impression of a single strip projection system. In front view, a single projection surface is created. The dimensions of such an assembly are defined by the number of juxtaposed modules. Thus optical signatures and specific projectors can be achieved by choosing the number and location of identical modules according to the invention and the number and location of the assemblies, with a variable or identical number of modules per assembly, without however require a specific development and implementation phase. The kit solution for designing projectors for motor vehicles proposed by the invention therefore reduces the time and production costs of a variety of such projectors. The relative arrangement in the space of different modules all identical to each other makes it possible to respond to a great variety of stylistic demands.

    [0006] In the following description, like reference numerals will be used to describe similar concepts through different embodiments of the invention. Unless specifically indicated otherwise, technical features described in detail for a given embodiment may be combined with the technical features described in the context of other exemplary and nonlimiting exemplary embodiments. FIG. 1 is a simplified representation of a lighting module 1 according to the invention. The projector is usually represented according to the lighting direction. The projector is partly represented via its dioptres.
    [0007] The lighting module 1 comprises, according to the direction of illumination, a primary optical element 6 and a projection lens 4. The primary optical element comprises an optical axis 10 according to which it illuminates and according to which it concentrates and generally folds its rays.
    [0008] The lighting module comprises at least one light source 12, such as a light-emitting diode, LED or a laser diode, which produces light rays penetrating the optical system via the primary optical element 6. The module 1 may further comprise a housing which is not represented for the sake of clarity. The light sources of the module are fed in known manner by a device for controlling the supply of light sources which will not be described in detail in the context of the present invention. Such devices are known to those skilled in the art and generally comprise a converter which makes it possible to convert a voltage supplied by a current source of a motor vehicle, such as a car battery, into a suitable charging voltage. to supply the source or sources of light. The power control device makes it possible, in a known manner for the ADB systems, to selectively supply independently each group of light sources that participate in the creation of a projected pixel.
    [0009] In the example of Figure 1 the primary optical element 6 comprises at least one light guide 14, four in this case, and a body with a curved output diopter 16. The body of the primary optical element forms a correction portion with a dome-shaped surface 16, for example hemispherical. Each light guide 14, also called waveguide or optical guide, is associated with a primary light source 12, it conducts light through the material of the element. It has an elongation, possibly principal, along the optical axis 10. The material constituting the light guides 14 and the body is transparent. This is a material for optical lens, such as an organic material or possibly glass and came from material. Such an optical element is well known to those skilled in the art and can be implemented as described in EP2743567A1. Alternatively, the primary optical element may include microlenses or pads to guide the light emitted by the light sources. The projection lens 4 comprises an input diopter 22 facing the output diopter 16 of the primary optical element, and an output diopter 24. Each of these diopters is continuous. The projection lens 4 forms a ribbon of continuous material. The surface of the exit diopter 24 follows the geometry of a toric surface obtained by rotating a circle about an axis offset from its center. Two identical modules therefore have two identical surface elements of the same torus and can be assembled horizontally in the normal direction of assembly to form a continuous surface element of the same torus having a double surface. The surface thus created by the exit dioptres 24 can be enlarged by adding identical modules. According to a preferred embodiment of the invention, the radius of curvature R of the output diopter 24 of the projection lens 4 is given by the following equation: R = L (sin (c1) 1) 2 2 in which L is the width of the projection lens seen from the front and a = k (AE)) / N. AE) is the angular width in degrees of a light band projected by the module and k and N are positive integers. The width of a light band or a pixel is substantially equal to the width 20 at half height of the intensity profile. The quantities involved in equation 1.1 are illustrated schematically in FIG. 2a, which shows a schematic view from above of a lighting module according to the invention in the case where a = AB. L is the width of the projection lens seen from the front, in the case illustrated, it is the length of a rope of a circle of radius R which centers on the location of the single light source 12 of the module, the rope being supported by an angle Ae. 30 AE) is the angular width in degrees of a light band projected by the module.
    [0010] Preferably, the radius of curvature R is greater than 200 mm and preferably between 400 and 1200 mm. The angle AE) is preferably between 1.5 ° and 3 °.
    [0011] The entry face 22 of the projection lens 4 preferably comprises a convex geometry in the horizontal direction, as indicated in FIG. 2a. The convexity is preferably centered on the optical axis 10 of the primary optical element.
    [0012] Figure 2b schematically illustrates the light band that the module 1 of Figure 2a is able to project on the road in front of the vehicle equipped with the module. The single light source 12 creates a single band of angular width, 8, E). Similar modules capable of creating a plurality of parallel strips of the same width (contiguous or spaced each with an angular width, 8, E) using a plurality of light sources and / or primary optical elements can be realized by the person skilled in the art by using a projection lens that complies with the formula according to the invention. The example which is described below illustrates the impact of the factor N which is involved in the calculation of the radius of curvature of the output diopter of the projection lens according to the invention. When several identical modules, therefore of the same radius of curvature R are placed side by side, the integer factor N defines a multiplication factor of the resolution obtained by the juxtaposition of the modules. This is illustrated by Figures 3a and 3b as an example. In the case of Figure 3a, two identical modules (N = 1) similar to that illustrated in Figure 2a are juxtaposed horizontally in the normal direction of assembly. The two light bands created by the light source 12 of the first module and the light source 12bis of the second module both have an angular width equal to Ae, and they do not overlap laterally. Thus, the angle ΔE) between the optical axes of the two adjacent modules is substantially equal to the angular width of a light band at the effects of cutoff blur. This angle gives the resolution of the beam obtained.
    [0013] In the case of FIG. 3b, the factor N is equal to 2. A lateral superposition of the halves of projected light strips is obtained. The horizontal angle between the optical axes of the two contiguous modules is substantially, with blurring effects, at half the angular width of a light segment. The resolution is doubled. With increasing N, the resolution of the overall beam obtained by an assembly of identical modules increases, while the overall width of this beam decreases. The factor k which is involved in the calculation of the radius of curvature of the output diopter lo of the projection lens according to the invention is a predefined integer. It corresponds to a choice of embodiment of the overall strip light beam generated by a lighting device comprising at least two modules according to the invention. The factor k is the number of pixels constituting a light group coming from a single module until it encounters a pixel coming from another module of the lighting device, when the overall beam is traveled in a direction determined in its width. (from left to right or vice versa). A luminous group is thus called a set of contiguous or overlapping pixels produced exclusively by a module, each module projecting at least one light group 20, said groups being able to be contiguous or spaced apart. A light group contains at least one pixel. The overall beam of a strip lighting device consists of a succession of light groups from at least two identical modules according to the invention, said groups being contiguous or overlapping according to the selected factor N. For practical reasons of modularity and compactness of the module of the invention, k will be chosen less than or equal to 50, more generally less than or equal to 20 and preferably less than or equal to 10. Similarly, N will advantageously be between 1 and 4, terminals included. A first example is illustrated diagrammatically in FIG. 4, which shows two sets of k = 2 projected pixels 112 by a first module, as well as two sets of pixels 112bis projected by a second module identical to the first module. In the illustrated case the curvature according to equation 1.1 uses the factors k = 2 and N = 1 respectively. The pixels projected by the two identical modules intertwine to create a beam consisting of contiguous pixels.
    [0014] Other examples of the possibility of overall band-beam configuration generated by at least two associated modules of the invention in a strip lighting device are illustrated in FIGS. 7A and 7B. In these two figures, the pixels from each of the modules have not been shown superimposed to facilitate understanding, it being understood that the overall beam results from the sum of the pixels. In FIG. 7A, N = 1 and k = 1, each module generating two spaced pixels. In FIG. 7B, k = 1 and N = 2, each module generating three distinct pixels contiguous, the pixels of the first module and the second module then being overlapped.
    [0015] In all embodiments, in order to facilitate the horizontal juxtaposition of the modules, it is preferable that the lateral extent of the module, or of its case, in the normal mounting direction is increasing or decreasing in the direction of the light emitted by the module. Preferably, the extent of the rear portion is strictly less than that of the front portion where the projection lens is housed.
    [0016] Advantageously, the rear part is at least five times smaller than the front part. Preferably, the back portion is 5% to 50% smaller than the front portion. This is illustrated by the schematic drawing of FIG. 5, which shows a view from above of an assembly of eight identical modules arranged in lateral contact and in accordance with the invention.
    [0017] Alternatively, the extent of the front portion is strictly less than that of the rear portion. In this case the front portion is advantageously at least five times less wide than the rear part. Preferably, the front portion is 5% to 50% narrower than the rear portion. In all embodiments of the invention, an unillustrated intermediate lens can be positioned in the optical system between the primary optical element. 6 and the projection lens 4. The intermediate lens is configured to concentrate the radiation from the output diopter of the primary optical element with which it is associated on the projection lens. In all the embodiments of the invention, the module may comprise lateral alignment or positioning means, which make it possible to facilitate the juxtaposition of two identical modules horizontally in the normal direction of assembly, so that the The output dioptres of the modules form a continuous toric surface element. The alignment means may be shaped in the projection lenses or may be included in support means which allow the different components of the module to be held at their intended location.
    [0018] Alternately the alignment means may be provided in a non-illustrated heat sink element of the module. As an example, FIG. 6 shows an internal section of a projection lens according to one embodiment of the invention. The section is made by a vertical plane transverse to the optical axis. The alignment means comprise notches 26 and protrusions 25 on the lateral edges of the projection lens. The location of the notches and protrusions is chosen so that the protrusions of a first module according to the invention can engage in the corresponding notches of an identical module juxtaposed horizontally in the normal direction of mounting the module. . Other geometries of notches and protrusions are obviously conceivable without departing from the scope of the invention. The present description and the examples illustrated by the figures allow one skilled in the art to create a variety of lighting modules according to the invention using different parameters in equation 1.1. Assemblies of such modules can then be used to create motor vehicle band projectors with different optical signatures. 30
