LIGHT MODULE FOR A MOTOR VEHICLE

Description

[0001] The present invention relates to a lighting module for vehicles. It finds a particular, but not limiting, application in motor vehicles.

[0002] In the field of motor vehicles, a vehicle lighting module well known to those in the trade includes: at least one light source configured to emit light rays, at least one collector associated with said at least one light source, said collector being configured to collect and direct the light rays from said at least one light source, at least one optical output element configured to transmit the light rays outwards from said motor vehicle to form a light beam.

[0003] The light module is integrated into a lighting system and also includes one or more masks, which are styling elements that enclose the light module. The lighting system is a motor vehicle headlight. The light beam can be adjusted to have both vertical and lateral movement. Vertical movement is useful for compensating for the vehicle's attitude, which varies from one vehicle category to another and according to the vehicle's load, and for directing the light beam to avoid dazzling an occupant of an oncoming vehicle. Lateral movement is useful for adjusting the alignment between two light modules and for ensuring proper alignment of the light beam with the vehicle's axis. For this purpose, all the components (at least one light source, at least one collector, and at least one optical output element) of the light module are set in motion.

[0004] One drawback of this prior art is that a structural component is required to move the entire lighting module. Consequently, the combined structural component and lighting module are quite bulky.

[0005] Known light modules are described in documents EP 1270322 A and US 6220735 B.

[0006] In this context, the present invention aims to provide a vehicle lighting module that proposes to solve the aforementioned problem.

[0007] To this end, the invention proposes a vehicle lighting module, as defined in claim 1, said lighting module comprising: at least one light source configured to emit light rays, at least one collector associated with said at least one light source, said collector being configured to collect and direct the light rays from said at least one light source towards at least one optical output element, said at least one optical output element configured to transmit said light rays to the outside of said vehicle to form a light beam, characterized in that said light module further comprises a system for lateral relative displacement of said at least one collector and of said at least one associated light source with respect to said at least one optical output element so as to move said light beam laterally.

[0008] By "relative lateral displacement" we understand that the displacement includes at least one lateral translation. Thus, the at least one collector and the said at least one associated light source shift laterally with respect to the at least one output optical element, that is to say that every point of the at least one collector or of the said at least one associated light source shifts laterally with respect to the at least one output optical element.

[0009] Thus, as we will see below, moving at least one collector and at least one associated light source relative to at least one output optical element allows for lateral and / or vertical movement without having to move all the parts of the optical module. This eliminates the structural component that was dedicated to this purpose. It also avoids play in the style parts and consequently prevents light leakage through these gaps. The front of the light module remains fixed, being formed by at least one output optical element and the style parts, while the rear of the optical module is set in motion for lateral and / or vertical movement, the rear being formed by at least one collector and at least one light source.

[0033] Identical elements, whether structural or functional, appearing on different figures retain the same references unless otherwise specified.

[0034] The light module 1 for vehicle 2 according to the invention is described with reference to figures 1 à 41 In a non-limiting embodiment, vehicle 2 is a motor vehicle. A motor vehicle is defined as any type of motorized vehicle. This embodiment is taken as a non-limiting example in the following description. In the following description, vehicle 2 is thus also referred to as motor vehicle 2.

[0035] As illustrated on the [ Fig.1 The light module 1 is configured to be integrated into the housing of a light device 4. In a non-limiting embodiment, the light device 4 is a projector. The light device 4 thus comprises a housing (not shown) in which at least one light module 1 is integrated. In a non-limiting embodiment, the light device 4 includes an output lens (not shown) that closes the housing. In another non-limiting embodiment, it is said at least one optical output element 12 described later that closes said housing.

[0036] Light module 1 includes: at least one light source 10, at least one collector 11 associated with said at least one light source 10, at least one optical output element 12, a lateral relative displacement system 13 of said at least one collector 1 and of said associated light source 10 with respect to said at least one optical output element 12 so as to move said light beam F1 laterally. The lateral relative displacement system 13 is otherwise called the lateral displacement system 13.

[0037] As illustrated on the [ Fig.1 In a non-limiting embodiment, the light module 1 comprises: a plurality of light sources 10, a plurality of collectors 11 each associated with a light source 10, a plurality of optical output elements 12, a system for lateral relative displacement 13 of said plurality of collectors 11 and their associated light sources 10 with respect to said optical output elements 12 so as to move said light beam F1 laterally.

[0038] In the illustrated, non-limiting example, the light module 1 comprises: four light sources 10, four collectors 11 each associated with a light source 10, two optical output elements 12.

[0039] In the non-limiting example shown, one of the output optical elements 12 is arranged opposite one of the four collectors 11, and the other of the output optical elements 12 is arranged opposite the other three collectors 11.

[0040] This non-limiting embodiment is taken as a non-limiting example in the remainder of the description. Note that on the [ Fig.1 ], the light sources 10 are illustrated by transparency.

[0041] In a non-limiting embodiment illustrated in the top view of the [ Fig.3 ] and on the cross-sectional view of the [ Fig.4 ], the light module 1 further includes at least one cover 16, otherwise called a mask 16 or style piece 16, for closing the light module 1. Said at least one cover 16 extends from the collectors 11 to said optical output elements 12.

[0042] In a non-limiting embodiment illustrated on the [ Fig.2 ], the light module 1 further comprises a vertical relative displacement system 14 of said plurality of collectors 11 and their associated light sources 10 with respect to said optical output elements 12 so as to vertically move said light beam F1. On the [ Fig.2 ], the lateral relative displacement system 13 has only been partially illustrated. It should be noted that on the [ Fig.2 Above the line L, shown in alternating dashed and dotted lines, the elements are illustrated in top view, while below the line L, the elements are illustrated in side view. The lateral relative displacement system 13 is also called the lateral displacement system 13.

[0043] The elements of the light module 1 are described in detail below.

[0044] In a non-limiting embodiment, the light sources 10 are semiconductor light sources. In a non-limiting embodiment, the semiconductor light sources are part of a light-emitting diode or a laser diode. By light-emitting diode, we mean any type of light-emitting diode, whether in non-limiting examples LEDs (Light Emitting Diodes), OLEDs (Organic LEDs), AMOLEDs (Active-Matrix-Organic LEDs), or FOLEDs (Flexible OLEDs).

[0045] The light sources 10 are configured to emit R1 light beams (illustrated on the figures 1 And 2 ). These light rays R1 will arrive at the plurality of collectors 11. The collectors 11 include a support 11.1 (illustrated on the figures 4 And 5 ) in the shape of a shell or cap, and a reflective surface 11.2 (illustrated on the figures 4 And 5 ) on the inner face of the support 11.1. In non-limiting embodiments, the reflective surface 11.2 comprises an elliptical or parabolic profile.

[0046] As illustrated on the [ Fig.5 The reflective surface 11.2, if it is of the elliptical type, has a second focal point 11.3 located at the front of the output optical element 12 and at a distance from the optical axis Aa of the light module 1. It should be noted that it is also possible for this focal point 11.3 to be located at the rear of the output optical element 12 and / or on the optical axis Aa, provided that it is close to said output optical element 12, so as to reduce the width of the light beam F1 at the level of the entrance face 12.1 of said output optical element 12. This makes it possible to reduce the height of the output optical element 12 and therefore to reduce the size of the light module 1.

[0047] Each collector 11 of said plurality of collectors 11 is associated with a light source 10. Each collector 11 is configured to collect and direct the light rays R1 from the associated light source 10 towards an output optical element 12, the light rays R1 being reflected on said reflective surface 11.2 of the collector 11. In a non-limiting embodiment, the plurality of collectors 11 forms a so-called multi-cavity reflector.

[0048] The light source 10 associated with a collector 11 is located at a focus of the reflective surface 11.2 of said collector 11 such that its light rays R1 are collected and reflected along the optical axis Aa (illustrated on the [ Fig.5 of the luminous module 1. In a non-limiting embodiment, at least a portion of these reflected rays have angles of inclination α in a vertical plane with respect to said optical axis Aa that are less than or equal to 25°, so as to be in the so-called Gaussian conditions, allowing for stigmatism, i.e., sharpness of the projected image. In a non-limiting variant of the embodiment, the angles of inclination α are less than or equal to 10°.

[0049] In a non-limiting embodiment, the light sources 10 are arranged on a PCB support (“Printed Circuit Board”) (not shown) which is itself attached to a heat sink (not shown) which cools the light sources 10. The heat sink is attached to the collectors 11.

[0050] As we will see below, the assembly of collectors 11 - light sources 10 - radiator can be set in motion so that the light beam F1 can move vertically and / or laterally, while the output optical element 12 remains stationary as well as the mask(s) 16 of said light module 1. Thus, the rear of the light module 1 formed by the assembly of collectors 11 - light sources 10 - radiator moves while the front formed by the output optical element 12 and the mask(s) 16 remains fixed.

[0051] The optical output element 12 is configured to transmit the light rays R1 outwards from the motor vehicle 2 to form a light beam F1 along the optical axis Aa of said light module 1. It comprises an input face 12.1 (illustrated in the figures 1 And 5 ) which receives the light rays R1 and an exit face 12.2 (illustrated on the figures 1 And 5) through which the light beam F1 formed by the light rays R1 exits. Said at least one optical output element 12 has a focus 12.3 (illustrated on the [ Fig.5 ]) which is located along the optical axis Aa, at the level of the light source 10 or even behind said light source 10. In this case the focus 12.3 is located at the level of the reflective surface 11.2 of the collector 11. It should be noted that it is also possible that this focus 12.3 is located behind or in front of the reflective surface 11.2.

[0052] In a non-limiting embodiment, the light beam F1 is a segmented light beam. Certain segments can thus be extinguished to avoid dazzling an oncoming vehicle, for example, motor vehicle 2. In this case, the reflective surface 11.2 of the collectors 11 has several vertical sectors.

[0053] In a first non-limiting embodiment, the light beam F1 is a road beam, namely it has a flat cut-off.

[0054] In a second, non-limiting embodiment, the light beam F1 is a kink-shaped beam, meaning it has an inclined cut and a flat cut. The flat cut and the inclined cut define the upper part of their respective portions of the light beam F1. It thus has two parts: a first portion F1a, which is an inclined cut, including an inclined section; and a second portion F1b, which is a flat cut. The two parts F1a and F1b are described later. In a non-limiting embodiment, the inclined cut includes an inclined section and a flat section forming an angle between them.

[0055] In a non-limiting embodiment illustrated on the figures 1 or 5Said at least one output optical element 12 is a projection lens. It is a converging projection lens that projects the image of the reflecting surface 11.2 to infinity. In non-limiting embodiments, the projection lens is plano-convex, convex-convex, or a meniscus. The projection lens is thin. In a non-limiting embodiment, its thickness is less than 7 mm (millimeters). In one embodiment, said at least one output optical element 12 is planar or has a slight curvature. In a non-limiting example, the curvature has a minimum radius of curvature of 200 mm (millimeters). Below this radius, in the case of a light beam F1 comprising two parts F1a and F1b described later, the vertical displacement will not be the same. Said at least one output optical element 12 is thus relatively straight with respect to the vehicle axis OX. Viewed from above, it is relatively straight.This allows for a sufficient vertical deflection angle (7° in a non-limiting example). And the lateral displacement will not distort the flat cutoff F1b of the light beam F1 described later.

[0056] In a first, non-limiting embodiment, said at least one optical output element 12 is perpendicular to the optical axis Aa of the light module 1, i.e., it is not inclined with respect to the vehicle axis OX on a horizontal plane when the light module 1 is in the mounting position on the vehicle 2. As illustrated in the [ Fig.6 ], the two optical output elements 12a, 12b shown are not inclined. In a second, non-limiting embodiment, said at least one optical output element 12 has an angle of inclination β on said horizontal plane with respect to the perpendicular to the optical axis Aa of the light module 1, namely it is inclined with respect to the vehicle axis OX, the optical axis Aa being substantially parallel to the vehicle axis OX. As illustrated in the [ Fig.7 In the top view, the two optical output elements 12a, 12b shown are inclined. The horizontal plane is a plane parallel to the ground which contains the vehicle axis OX.

[0057] In a non-limiting embodiment, the tilt angle β has a maximum value of 15°. In another non-limiting embodiment, the tilt angle β is equal to 3°. This results in an output optical element 12 that is only slightly inclined relative to the vehicle axis OX. This maximizes the range of movement within which the cutoff of the light beam F1 is not distorted. If the tilt angle β is too steep, the cutoff of the light beam F1 will indeed be distorted.

[0058] In a non-limiting embodiment, the light module 1 comprises a plurality of optical output elements 12, of which one part 12a of the optical output elements 12 is associated with a first portion F1a of said light beam F1 and the other part 12b of the optical output elements 12 is associated with a second portion F1b of said light beam F1. As illustrated in the [ Fig.1 ] or the [ Fig.5 [ ], there are two optical output elements 12, one 12a associated with the first portion F1a of said light beam F1 and the other 12b associated with the second portion F1b of said light beam F1. This allows for the creation of a coded beam. The first portion F1a represents the inclined cutoff, also called the "kink." It is also referred to as the inclined cutoff F1a or simply the cutoff F1a. The second portion F1b represents the flat cutoff, also called the "flat." It is also referred to as the flat cutoff F1b or simply the cutoff F1b. In the non-limiting example illustrated in the figures 1 And 2A collector 1 is used to create the first portion F1a ("kink") of the light beam F1, and three collectors 11 are used to create the second portion F1b ("flat") of the light beam F1. This non-limiting embodiment of the plurality of output optical elements 12 to form a light beam F1 with a slanted cutoff and a flat cutoff is taken as a non-limiting example in the following description. It should be noted that in this case, in a non-limiting embodiment, the two output optical elements 12a and 12b share the same common longitudinal axis perpendicular to the vehicle axis OX.

[0059] The lateral relative displacement system 13 and the vertical displacement system 14 allow for the combination of lateral and vertical movement of the collectors 11 and the associated light sources 10, enabling the light beam F1 to move laterally and / or vertically. It should be noted that the entire assembly—collectors 11, light sources 10, and heat sink—moves, but for the sake of simplicity, we will refer only to the movement of the collectors 11 hereafter. The lateral and / or vertical movement occurs within the light module 1.

[0060] As illustrated on the figures 8 à 10 The lateral relative displacement system 13 allows the collectors 11 to be moved laterally relative to the output optical elements 12, whether: to the left (PH- position) relative to a vertical plane containing the vehicle axis OX to have an output beam F1 oriented to the right H+ ([ Fig.9 ] in rear view) relative to a nominal lateral position H0 of the light beam F1 ( [ Fig.8 ] in rear view), said nominal lateral position H0 of the light beam F1 corresponding to a nominal lateral position PH0° of the collectors 11, or to the right (position PH+) with respect to said vertical plane to have an output beam F1 oriented to the left H-([ Fig.10 ] in rear view) relative to this nominal lateral position H0°. Note that the vertical plane is defined when the light module 1 is in the mounting position on the motor vehicle 2.

[0061] This allows us to obtain respectively a light beam F1 whose luminous image is represented in iso-candela on the figures 11 à 13 Each curve represents a constant luminous intensity level called iso-candela. Generally, the nominal lateral position H0° is defined by the horizontal; and the horizontal is defined when the light module 1 is in its mounting orientation in the normal operating position. In other words, the horizontal is the plane of the road on which the motor vehicle 2 is traveling. Note on the figures 8 à 10 that the collectors 11 positioned at a nominal vertical position PV0° corresponding to a nominal vertical position V0° of the light beam F1.

[0062] As can be seen, the inclined cut F1a of the light beam F1 on the [ Fig.12 ] is located further to the right H+ than that on the [ Fig.11 ] (nominal lateral position H0). And, the F1a cutoff of the light beam F1 on the [ Fig.13 ] is located further to the left H- than that on the [ Fig.11 As will be seen later, the lateral displacement is achieved through a circular translation of the collectors 11. In a non-limiting embodiment, the lateral displacement of the collectors 11 and the associated light sources 10 generates a lateral displacement angle of between ±5° and, in particular, between ±3° for the light beam F1. In a non-limiting variant, the lateral displacement angle is equal to between ±3° and ±3°. These values ​​are understood as the displacement of the light beam F1 along the isocandela. It should be noted that a lateral displacement of 2 mm of the collectors 11 corresponds to a lateral displacement of the light beam F1 of approximately 2°. It should be noted that the lateral displacement has no effect on the flat cutoff F1b.

[0063] As illustrated on the figures 14 à 16 The vertical relative displacement system 14 allows the collectors 11 to be moved vertically relative to the output optical elements 12, whether: upwards (position PV+, also called high position) relative to the horizontal plane parallel to the ground which contains the vehicle axis OX in order to have a light beam F1 directed downwards V- ([ Fig.15 ]) relative to a nominal vertical position V0° ([ Fig.14 ]), or downwards (PV- position, also called the low position) relative to said parallel horizontal plane to have a light beam F1 directed upwards V+ ( [ Fig.16 ]) relative to this nominal vertical position V0°. Note that the horizontal plane is defined when the light module 1 is in the mounting position on the motor vehicle 2.

[0064] This allows the light beam F1 to be moved below or above its nominal vertical position V0°. As will be seen later, the relative vertical displacement is achieved by rotating the collectors 11. In a non-limiting embodiment, the relative vertical displacement of the collectors 11 generates a vertical deflection angle of between ±10° and, in particular, between ±7° for the light beam F1. In a non-limiting variant, the vertical deflection angle is approximately ±7° for the light beam F1. This value refers to the displacement of the light beam F1 along the isocandela axis.It should be noted that the vertical displacement being achieved by a rotation about the axis of rotation AD (described later) at the level of the output optical elements 12, a mechanical rotation of 1° corresponds to a vertical displacement of the light beam F1 of approximately 1°.

[0065] THE figures 17 à 19 , And 23 à 25These diagrams illustrate different horizontal and vertical positionings of the collectors 11 relative to the output optical elements 12. A nominal position PV0° / PH0° is defined by a nominal vertical position PV0° and a nominal lateral position PH0°, which corresponds to a nominal position V0° / H0° of the light beam F1 defined by a nominal vertical position V0° and a nominal lateral position H0° of the light beam F1. By nominal position V0° / H0°, we mean the position of the light beam F1 set on a motor vehicle 2 whose dimensions are all at their nominal values. As will be seen below, when the collectors 11 move to the right, this directs the light beam F1 to the left, while when the collectors 11 move to the left, this directs the light beam F1 to the right.Furthermore, when the collectors 11 move upwards, the light beam F1 tilts downwards, while when the collectors 11 move downwards, the light beam F1 tilts upwards.

[0066] Thus, as illustrated on the figures 17 à 19 , the collectors 11 are positioned in a vertical PV+ position located above the nominal vertical PV0 position, otherwise known as the high PV+ position. Furthermore, on the [ Fig.17 ], the collectors 11 are positioned at the nominal lateral position PH0°, while on the [ Fig.18 ], they are positioned in the lateral position on the left PH-, and on the [ Fig.19 ], they are positioned laterally to the right PH+. This allows us to obtain respectively a light beam F1 whose image is represented on the figures 20 à 22 As can be seen in these figures, the light beam F1 is located at a vertical position V- below the nominal vertical position V0°. Furthermore, the cutoff F1a of the light beam F1 on the [ Fig.21 ] is located further to the right H+ than that on the [ Fig.20 ] (nominal lateral position H0°). And, the F1a cutoff of the light beam F1 on the [ Fig.22 ] is located further to the left H- than that on the [ Fig.20 ].

[0067] Thus, as illustrated on the figures 23 à 25 , the collectors 11 are positioned in a vertical PV- position located below the nominal vertical position V0°, otherwise called the low PV- position. Furthermore, on the [ Fig.23 ], the collectors 11 are positioned at the nominal lateral position PH0°, while on the [ Fig.24 ], they are positioned in the lateral position on the left PH-, and on the [ Fig.25 ], they are positioned laterally on the right PH-. This allows us to obtain respectively a light beam F1 whose image is represented on the figures 26 à 28 As can be seen in these figures, the light beam F1 is located at a vertical position V+ above the nominal vertical position V0°. Furthermore, the cutoff F1a of the light beam F1 on the [ Fig.27 ] is located further to the right H+ than that on the [ Fig.26 ] (nominal lateral position H0°). And, the F1a cutoff of the light beam F1 on the [ Fig.28 ] is located further to the left H- than that on the [ Fig.26 ].

[0068] In summary: The nominal lateral position PH0° of the collectors 11 corresponds to the nominal lateral position H0° of the light beam F1, the lateral position PH- of the collectors 11 corresponds to the lateral position H+ of the light beam F1, the lateral position PH+ of the collectors 11 corresponds to the lateral position H- of the light beam F1, the nominal vertical position PV0° of the collectors 11 corresponds to the nominal vertical position V0° of the light beam F1, the vertical position PV- of the collectors 11 corresponds to the vertical position V+ of the light beam F1, and the vertical position PV+ of the collectors 11 corresponds to the vertical position V- of the light beam F1.

[0069] The lateral relative displacement system 13 and the vertical relative displacement system 14 are now described in detail below at the kinematic level with reference to figures 29 à 41 On the figures 29 à 41 Also illustrated are the output optical element 12 and the collectors 11 forming the reflector.

[0070] As illustrated on the [ Fig.1 ] and the [ Fig.29 ], the lateral relative displacement system 13 comprises: a pivot joint centered at A and with axis AE and a ball joint centered at D arranged laterally on either side of said at least one optical output element 12, a pivot joint centered at B and a pivot joint or ball joint centered at C arranged on either side of the plurality of collectors 11, the pivot joint(s) having an axis parallel to AE, two parallel connecting rods G1, G2 of the same length, each respectively connecting the pivot joint centered at A and the pivot joint centered at B, and the ball joint centered at D and the pivot joint or ball joint centered at C so as to form a parallelogram ABCD, a primary actuator H1 configured to rotate the pivot joint centered at A in a substantially transverse direction AD so as to move said plurality of collectors 11 transversely, a primary annular linear connection centered at F connecting said primary actuator H1 to one of said connecting rods G1,G2 to form a primary crank M1.

[0071] More precisely, the centers A, B, C, and D form the corners of parallelogram ABCD, and parallelogram ABCD is formed by the segments AB, BC, CD, and DA. For simplicity, the term parallelogram ABCD is used to refer to the assembly formed by the two connecting rods G1 and G2, the output optical element 12, and the collectors 11.

[0072] For simplicity, we refer to the links A, B, C, D, E, F as links with respective centers A, B, C, D, E, F. The primary crank M1 is also called the lateral thrust crank M1 or the lateral crank M1. The axis AE passes through centers A and E.

[0073] It is worth remembering that a ball joint can rotate in all directions while a pivot joint rotates around an axis and cannot perform translation.

[0074] The transverse displacement of the plurality of collectors 11 is a circular translational movement over a small angular stroke. Circular translational movement is a translation along a trajectory that is a portion of a circle. Recall that the lateral displacement angle is between ±5° and, in particular, between ±3° for the light beam F1.

[0075] It should be noted that on the [ Fig.29 The optical output element 12 is connected to the symbol representing a mass, which means that said optical output element 12 is fixed relative to the motor vehicle 2. It does not move and remains stationary while the collectors 11 move. It should be noted that pivot joints, which are rotating joints, are known for their reliability. Unlike sliding systems, there is no risk of jamming or binding. On the other hand, the movement is circular (instead of rectilinear). However, if we are working with a small angular displacement and the parallelogram ABCD is nominally a rectangle, then the circular translation is close to the rectilinear translation.

[0076] The lateral push crank M1 connects the primary annular linear link F to one of the connecting rods G1, G2 so as to form the lever arm AF (for G1) or the lever arm DF (for G2). The crank M1 is rigidly coupled to one of the connecting rods G1, G2, here G1 in the illustrated non-limiting example.

[0077] In a non-limiting embodiment, the collectors 11, the output optical element 12, and the connecting rods G1, G2 are configured to assume a position PH0° in which the parallelogram ABCD forms a rectangle. In a non-limiting variant, this position is the nominal position PH0° described previously. This allows for the most lateral movement possible without an axial component. This results in a minimal variation in the distance between the collectors 11 and the associated output optical elements 12.

[0078] Parallelogram ABCD is deformable in that angles DCB and CBA can change, but the sides are of equal length with AB=DC and AD=BC. The line passing through the center of the pivot joint A and the center of the annular linear joint F, and the line passing through the center of the pivot joint A and the center of the pivot B, are perpendicular to each other.

[0079] The two connecting rods G1 and G2 are also called lateral connecting rods G1 and G2. Each connecting rod G1 and G2 rotates relative to the axis AE and to an axis parallel to AE passing through the ball joint D, respectively. The connecting rods G1 and G2 are parallel to each other and of equal length (AB = CD). The axis AE passes through the centers A and E.

[0080] The primary actuator H1 is also known as the lateral actuator H1. In a non-limiting configuration, the lateral actuator H1 is a manual screw that is adjusted at the factory or in a garage. Therefore, a screw-nut connection is used in this case. It allows for precise centering of the light beam F1 onto the vehicle 2, taking into account manufacturing tolerances. The primary actuator H1 can move forward or backward.

[0081] Since the lateral displacement, also called transverse displacement, of the plurality of collectors 11 is a circular translational movement, the primary actuator H1 rotates the pivot joint centered at A in a substantially transverse direction AD. Thus, the coupling of the pivot joint A and the ball joint D defines an axis AD (passing through centers A and D) for the lateral movement. Generally, the transverse direction AD corresponds to the horizontal direction when the module is mounted on the motor vehicle 2.

[0082] In a non-limiting embodiment, the pivot joint centered at A and with axis AE is achieved by means of a ball joint centered at A and a secondary annular linear joint centered at E. The centers A and E are not coincident. The secondary annular linear joint E determines the direction of rotation at the ball joints A and D. The ball joint A and the secondary annular linear joint E form an equivalent pivot.

[0083] The two pivot joints B and C have their axis of rotation parallel to the axis AE. This allows the parallelogram ABCD to be deformable to create lateral movement.

[0084] Note that a linear annular joint is schematically represented by a ball cooperating within a hollow cylinder. Note also that a linear annular joint is a ball joint capable of translating in a predetermined direction. In a non-limiting embodiment, the predetermined direction is the axis AE.

[0085] Thus, in a non-limiting embodiment, the primary annular linear link F has an axis parallel to the axis AE. This creates a slight hyperstaticity during the lateral displacement of the lateral relative displacement system 13, but this is managed thanks to the flexibility of the parts, the operating clearances and the small amplitude of the deformations required.

[0086] Indeed, during lateral movement, the female part of the primary annular linear linkage F describes a circle (in plane ABD, centered at A), since the connecting rod G1 rotates around axis AE. This female part becomes misaligned in the Y direction relative to the male part (ball), which necessarily remains aligned with the axis of the lateral actuator H1. However, this displacement is minimal. For example, with a lever arm AF of 50 mm and a stroke of 3°, the Y-axis movement is -0.07 mm. The flexibility of the parts and the operating clearances are sufficient to accommodate this variation. If the opposite configuration is chosen (annular linear linkage with axis AF), there is no longer any indeterminacy in the lateral movement. The ball simply moves 0.07 mm within the female part of the linkage (this is the usual role of annular linear links in a projector adjustment system). On the other hand, a greater hyperstaticity is created on the combined lateral and vertical movement.

[0087] On the [ Fig.29 The collectors 11 are in the nominal lateral position PH0° and in the nominal vertical position PV0°, referred to as the nominal position PV0° / PH0°, which corresponds to the light beam F1 in a nominal position V0° / H0° illustrated by the black square on the displacement grid g. By extension, the mechanical elements of the relative lateral displacement system 13 / vertical displacement system 14 are said to be in the nominal position PV0° / PH0°. For the sake of simplicity, only the nominal position V0° / H0° of the light beam F1 has been shown.

[0088] On the [ Fig.30 ], the collectors 11 perform a circular translational movement which allows the light beam F1 to be moved laterally to the left as indicated by the black square in the illustrated displacement grid g. As illustrated on the [ Fig.30 When the primary actuator H1 is pulled (in practice, the screw is loosened manually), the primary annular linear link F is pulled, creating a rotation around the axis AE which moves the entire set of collectors 11 to the right in the illustrated non-limiting example so that the light beam F1 moves to the left as indicated by the black square in the illustrated displacement grid g. To move the entire set of collectors 11 to the left so that the light beam F1 moves to the right, the primary actuator H1 must be pushed (in practice, the screw is tightened manually).

[0089] Thus, the linear movement (reference arrow S1) of the lateral actuator H1 causes a rotation (reference arrow S2) of the connecting rod G1 around the axis AE passing through the center of the ball joint A and the center of the secondary annular linear joint E. This then causes a deformation of the parallelogram ABCD. This results in a circular translational movement (reference arrow S3) of the reflector formed by the plurality of collectors 11 (it remains parallel throughout the trajectory to its nominal starting position PV0° of the [ Fig.29 ]).

[0090] As illustrated on the [ Fig.2 ] and the [ Fig.31 ], the vertical relative displacement system 14 comprises: the pivot joint centered at A and axis AE and a ball joint centered at D arranged on either side of said at least one optical output element 12, the pivot joint centered at B and the pivot joint or ball joint centered at C arranged on either side of the plurality of collectors 11, the pivot joint(s) having an axis parallel to AE, the two parallel connecting rods G1, G2 of the same length each connecting the centers A, D and the centers B, C located on the same side so as to form a parallelogram ABCD, said primary annular linear link centered at F.

[0091] For the vertical relative displacement system 14, in a non-limiting embodiment, said primary annular linear link F has an axis parallel to the axis AE.

[0092] For the vertical displacement system 14, in a non-limiting embodiment, the pivot joint with center A and axis AE is achieved by means of a ball joint with center A and an annular linear joint with center E. In a non-limiting embodiment, the secondary annular joint E has axis AE.

[0093] For the vertical displacement system 14, the primary annular linear link F is located on the axis AD passing through the centers A and D when said collectors 11 are in the nominal lateral position PH0° (as illustrated on the [ Fig.31 ]). This allows the collectors 11 to rotate around the axis AD. Thus, the coupling of the ball joint A and the ball joint D defines an axis of rotation AD for the vertical movement. Note that when outside the nominal lateral position PH0°, the primary annular linear joint F is not on the axis AD (as illustrated in the [ Fig.32 ]).

[0094] The annular linear linkage centered at E connects a secondary actuator H2 to one of said connecting rods G1, G2 to form a secondary crank M2, said secondary actuator H2 being configured to rotate the plurality of collectors 11 around the axis AD. The secondary crank M2 is also called the vertical push crank M2 or vertical crank M2.

[0095] Thus, the vertical displacement system 14 further includes said secondary actuator H2. The secondary actuator H2 is also called the vertical actuator H2.

[0096] It should be noted that the vertical displacement system 14 uses the ball joints A, D, the pivot joints B, C, and the connecting rods G1, G2 already used by the lateral relative displacement system 13. The lateral relative displacement system 13 and the vertical displacement system 14 thus share common elements. This results in a compact overall displacement system.

[0097] The vertical push crank M2 connects the secondary annular linear link E to one of the connecting rods G1, G2 so as to form the lever arm AE (for G1) or the lever arm DE (for G2). The crank M2 is rigidly coupled to one of the connecting rods G1, G2, here G1 in this non-limiting example. In another non-limiting example, the crank M2 can be coupled to a connecting rod G1, G2 that is different from the one used for M1.

[0098] The line passing through the center of the ball joint A and the center of the annular linear joint E, and the line passing through the center of the ball joint A and the center of the pivot joint B, are perpendicular to each other. This allows for lateral adjustment that is perfectly horizontal when in the nominal vertical position PV0°.

[0099] In non-limiting embodiments, the vertical actuator H2 is a manual screw that is factory-set or an electric actuator that, when the motor vehicle 2 is in operation, allows for dynamic correction of the vehicle's ride height, or a combination of both. The electric actuator includes an electronic motor. The secondary actuator H2 can move forward or backward. It is configured to rotate the ball joint A in a vertical direction so as to pivot the plurality of collectors 11 around the axis AD. It thus enables a rotational movement of the collectors 11 around the axis AD.

[0100] On the [ Fig.31 ], the collectors 11 perform a rotational movement that allows the light beam F1 to be moved vertically downwards as indicated by the black square in the illustrated displacement grid g. As illustrated on the [ Fig.31 When the vertical actuator H2 is pulled, the secondary annular linear link E is pulled, creating a rotation about an axis AD that moves all the collectors 11 upwards (the axis MM' of the collectors 11 tilting downwards), so that the light beam F1 is oriented downwards as indicated by the black square in the illustrated displacement grid g. To move all the collectors 11 downwards so that the light beam F1 tilts upwards, the secondary actuator H2 must be pushed.

[0101] Thus, the linear movement (reference arrow S4) of the vertical actuator H2 causes a rotation (reference arrow S5) of the reflector assembly (formed by the collectors 11) - two connecting rods G1, G2, around the axis passing through the center of the two ball joints A and D. This axis AD is substantially perpendicular to the longitudinal axis of the vehicle OX.

[0102] On the [ Fig.32 The collectors 11 perform a circular translational movement and also a rotational movement, which allows the light beam F1 to be moved laterally to the left and vertically downwards, as indicated by the black square in the illustrated displacement grid g. Both the lateral actuator H1 and the vertical actuator H2 are thus activated. It should be noted that for both lateral and vertical displacement, the distance between the two pivot joints C and B remains the same.

[0103] Figures 33 to 41, taken from the top and sides, illustrate the different possible positions of the collectors 11 and, consequently, of the light beam F1. The figures show how one moves from one position to another. In the non-limiting examples illustrated in these figures 33 à 41 For the sake of simplicity, only three collectors 11 and one output element 12 have been illustrated.

[0104] There [ Fig.33 [ ] illustrates the nominal position V0° / H0° of the light beam F1 and therefore the nominal position PV0° / PH0° of the collectors. For clarity, only the vertical and lateral position of the light beam F1 is shown in the figures.

[0105] There [ Fig.34 [ ] illustrates a high vertical position V+7° and a nominal lateral position H0° of the light beam F1. In this non-limiting example, the collectors 11 are positioned 7° below the nominal vertical position PV0° and in the nominal lateral position PV0°. In the side view, it can be seen that by pushing on the vertical actuator H2, the collectors 11 descend to the lower position (their axis MM' tilts upwards) so that the light beam F1 tilts upwards and thus moves from the nominal vertical position V0° to the high vertical position V+7°, while the output optical element 12 remains unchanged. The light beam F1 exiting the output optical element 12 will thus be oriented upwards and laterally centered as illustrated by the black square in the grid g shown.

[0106] There [ Fig.35 [Illustrates a high vertical position V+7° and a right lateral position H+3° of the light beam F1. In this non-limiting example, the collectors 11 are positioned 7° below the nominal vertical position PV0° and to the left of the nominal lateral position PH0°. They remain in the lowered position. In the top view, it can be seen that by pushing on the lateral actuator H1, the collectors 11 move to the left so that the light beam F1 is positioned 3° to the right of the nominal lateral position H0°, while the output optical element 12 has not moved. In the side view, it can be seen that the collectors 11 remain in the lowered position so that the light beam F1 remains oriented upwards V+7°, while the output optical element 12 has not moved.] The light beam F1 which exits the optical output element 12 will thus be directed to the right and upwards as illustrated by the black square in the illustrated grid g.

[0107] There [ Fig.36 [ ] illustrates a nominal vertical position V+0° and a right lateral position H+3° of the light beam F1. In the top view, it can be seen that the collectors 11 remain on the left so that the light beam F1 remains oriented to the right H+3°, while the output optical element 12 has not moved. To return to the nominal vertical position V0°, in the side view, the vertical actuator H2 is pulled. The collectors 11 move upwards to the nominal vertical position (their axis MM' returns to the horizontal) so that the light beam F1 returns to its nominal vertical position V0°. The light beam F1 exiting the output optical element 12 will thus be oriented to the right and vertically centered as illustrated by the black square in the grid g shown.

[0108] There [ Fig.37 Figure 1 illustrates a low vertical position (V-7°) and a right lateral position (H°+3°) of the light beam F1. In the top view, the collectors 11 remain on the left so that the light beam F1 remains on the right (H+3°), while the output optical element 12 has not moved. To reach the low vertical position (V-7°), the side view shows that the vertical actuator H2 is pulled again. The collectors 11 move upwards to the high position (their axis MM' tilts downwards) so that the light beam F1 moves from the nominal vertical position (V0°) to the low vertical position (V-7°). The light beam F1 exiting the output optical element 12 will thus be oriented downwards and to the right, as illustrated by the black square in the grid shown.

[0109] There [ Fig.38 Figure 1 illustrates a low vertical position (V-7°) and a nominal lateral position (H0°) of the light beam F1. To return to the nominal lateral position (H0), the lateral actuator H1 is pulled in the top view. The collectors 11 move to the right so that the light beam F1 moves from the right lateral position (H+3°) to the nominal lateral position (H0), while the output optical element 12 remains stationary. In the side view, the collectors 11 remain in the high position (their axis MM' remains inclined downwards). The light beam F1 exiting the output optical element 12 will thus be oriented downwards and laterally centered, as illustrated by the black square in the grid shown.

[0110] There [ Fig.39 [ ] illustrates a low vertical position V-7° and a left lateral position H-3° of the light beam F1. To transition to the left lateral position H-3°, the top view shows that the lateral actuator H1 is pulled again. The collectors 11 move to the right so that the light beam F1 changes from the nominal lateral position H0° to the left lateral position H-3°, while the output optical element 12 remains unchanged. In the side view, the collectors 11 remain in the high position (their axis MM' remains inclined downwards). The light beam F1 exiting the output optical element 12 will thus be oriented downwards and to the left, as illustrated by the black square in the grid g shown.

[0111] There [ Fig.40 Figure 1 illustrates a nominal vertical position V0° and a left lateral position H-3° of the light beam F1. In the top view, the collectors 11 remain on the right, while the output optical element 12 has not moved. To return to the nominal vertical position V0°, the side view shows that the vertical actuator H2 is pushed. The collectors 11 return to the nominal vertical position (their axis MM' returns to the horizontal) so that the light beam F1 moves from the low vertical position V-7° to the nominal vertical position V0°, while the output optical element 12 has not moved. The light beam F1 exiting the output optical element 12 will thus be oriented to the left and vertically centered, as illustrated by the black square in the grid shown.

[0112] There [ Fig.41[ ] illustrates a high vertical position V+7° and a left lateral position H-3° of the light beam F1. In the top view, it can be seen that the collectors 11 remain on the right, while the output optical element 12 has not moved. To transition to the high vertical position V+7°, in the side view, the vertical actuator H2 is pushed again. The collectors 11 move downwards to the lower position (their axis MM' tilts upwards) so that the light beam F1 moves from the nominal vertical position V0° to the high vertical position V+7°, while the output optical element 12 has not moved. The light beam F1 exiting the output optical element 12 will thus be oriented to the left and upwards, as illustrated by the black square in the grid g shown.

[0113] Of course, the description of the invention is not limited to the embodiments and the scope described above. Thus, in another non-limiting embodiment, the output optical element(s) 12 are mirrors instead of projection lenses.

[0114] Thus, the described invention offers the following advantages in particular: It allows the light beam F1 to be moved laterally, and also vertically. It allows for the combination of lateral and vertical movement of the light beam F1, preventing the entire light module 1 (output optical element 12, collectors 11, and light sources 10) from moving within the lighting device. Consequently, a person viewing the lighting device from outside the vehicle 2 will not see any parts move. For both vertical and lateral movement, it eliminates the play (of several millimeters) with the styling parts that is necessary when the entire light module 1 is moving within the lighting device. This play is required to control the angles of movement so that the light module does not strike the styling parts. Therefore, it prevents light leakage through these gaps.Furthermore, a person viewing the lighting system from outside vehicle 2 will not see any unsightly gaps or technical elements hidden behind the masks, such as, for example, electrical wires. This solution does not distort the light beam F1, since only the collectors 11 and light sources 10 move; it also allows for a more compact light module 1 within the lighting system.The housing of the lighting device is therefore smaller, eliminating a structural component used in the prior art that moved the entire lighting module 1. This reduces both size and weight, allows for sufficient lateral and vertical movement angles without distorting the light beam F1, and eliminates the need for an exit lens opposite the lighting module 1. This exit lens was necessary in the prior art solution when the entire lighting module 1 moved, to ensure its watertightness (against water, dirt, etc.). Without the exit lens, there is no light loss. The lighting module 1 is thus more efficient.
