    (54) LIGHT MODULE OF A MOTOR VEHICLE WITH COOLING DEVICE.
    FR 3 055 401 - A1 (5y A light module comprises a base, on which are mounted at least one light source and a cooling member (6) comprising at least two fins (24), connected to one another in an elastic manner and each comprising at least one dissipation wall (23) and a connection portion (30) thermally connected to the base by a thermal interface.
    The module comprises at least one wedge (40) capable of coming into contact with a part of a fin during the elastic bringing together of this fin with another fin.

    LIGHT MODULE OF A MOTOR VEHICLE WITH A COOLING MEMBER.
    The invention relates to the field of lighting and / or signaling devices for motor vehicles, and it relates more particularly to light modules intended to be mounted in a vehicle headlight and the cooling members associated with these modules.
    Motor vehicle headlamps are usually composed of a housing which is closed by a transparent wall through which emerge one or more light beams. This housing thus forms a housing for at least one light module, mainly comprising a light source and an optical system for shaping the light generated by the light source for the emission of the light beam by the projector.
    In recent years, the use of light sources consisting of at least one light emitting diode, or LED for the English acronym for "Light emitting diode", has spread due to their low energy consumption, their small size. and the quality of the lighting obtained. However, the use of light-emitting diodes has the disadvantage of producing heat, while heat is found to be detrimental to the proper functioning of light-emitting diodes. In fact, the more a light-emitting diode rises in temperature, the more the light flux it is likely to emit decreases.
    It is understood that this drawback is all the greater when the light module is designed to generate a beam requiring a high light intensity, such as for low beam, high beam or fog lights, the number of diodes electroluminescent and / or the power necessary for their operation then being high. Due to the sharp rise in temperature of the light module during use, it is necessary to reduce the temperature in the light module to avoid any malfunction of the light source or sources, inherent in excessive heat.
    To ensure effective cooling of the light emitting diodes, it is known to use a cooling member, which comprises on the one hand a part for fixing to a base itself carrying the light emitting diodes and on the other hand a heat dissipating part formed in particular by 'fins mounted in series elastically with respect to each other and carrying the fixing part, the spacing of the fins acting on the dimension of the fixing part. The fixing part also has the function of transferring calories by conduction from the base to the dissipating part of the cooling member.
    The fixing part is substantially flat so as to be pressed against a face of the base and it has connection portions forming the bearing surface on the base, as well as indexing means, for example orifices, arranged at the lateral ends. of this fixing part configured to cooperate with complementary indexing means, for example pins, carried by the base.
    The connection portions allow the attachment of the
    0 cooling using glue clamped between the carrier base of the light emitting diodes and the connection portions, and this glue allows the immobilization of the cooling member in the position defined by the cooperation of the indexing means.
    In practice, in order to take into account the manufacturing clearances which can cause a misalignment of the indexing means, a spacing of the indexing means of the cooling member is greater than the spacing of the pins carried by the base, it being understood that it is easier to compress the folded sheet forming the cooling member in order to match the indexing means carried by the sheet with the carried pins
    0 by the base than having to separate one of the other fins from the cooling member. Thus during assembly, a stress is exerted on the dissipating part to bring the fins laterally closer to one another, so as to bring the indexing means arranged at the lateral ends of the cooling member closer. This stress may cause the connection portions to overlap one another, and this may result in plastic deformation of one of the connection portions.
    It is understood that the plastic deformation of a connection portion as a result of an overlap on or under another connection portion implies a defect in the flatness of the whole of the fixing part, and therefore variable space between the base and each connection portions to be filled with glue. Either the quantity of glue is then insufficient to fill this larger space than that theoretically provided and the fixing of the cooling member is then penalized, or glue is placed in addition to fill the hole and the layer of glue used for fixing the cooling member is therefore not homogeneous. This excess glue and the resulting non-regular layer implies a reduction in the heat exchange efficiency between the base and the dissipating part, due to the insufficient dissipative thermal properties of the glue, and / or an inhomogeneous heat exchange.
    The present invention aims to solve the drawbacks described above by designing a light module having in particular a cooling member allowing the cooling of this module more effectively.
    In this context, the present invention relates to a light module comprising a base, on which are mounted at least one light source and a cooling member comprising at least two fins, connected to each other in an elastic manner and each comprising at least one dissipation wall. and a connection portion thermally connected to the base by a thermal interface, and in particular glue. According to the invention, the module comprises at least one wedge capable of coming into contact with a part of a fin when the elastic reconciliation of this fin with another fin.
    It is understood by "able to come into contact" that in a rest position of the light module, that is to say without being exerted on this module a constraint by an operator, the wedge is not in contact with the fin but facing it, and that it is this constraint, causing the elastic reconciliation of the fins which brings the wedge into contact with the fin, and which thus forms a stop preventing the overlapping of the connection portions carried respectively by the fins.
    According to a first series of characteristics, taken alone or in combination, and specific to the formation of the cooling member, it can be provided that:
    - the cooling member is formed from a single folded sheet;
    - the cooling member is made of plastic material, in particular molded;
    - The at least two fins are connected to each other in an elastic manner by a first fold;
    - The first fold connecting a fin to another fin extends one end of a dissipation wall of each of these fins;
    - The first fold connecting two fins between them extends at a distal end of the cooling member, that is to say an end opposite to the connection portions and to the base when the cooling member is mounted on the base ;
    - the fins include two dissipation walls;
    - The dissipation walls of the same fin are connected together by a second fold, the first and second folds being arranged at opposite ends of the cooling member;
    - the second fold between two dissipation walls extends to the right of at least one connection portion carried by one of the fins;
    - the dissipation walls are parallel to each other;
    - Each connection portion of a fin extends a dissipation wall of this fin by means of a fold;
    - The dissipation wall and the connection portion are substantially orthogonal;
    - The connection portions are arranged substantially in the same plane;
    - The second fold joining two fins is orthogonal to the fold (s) connecting the dissipation wall and connection portion.
    According to another series of characteristics, taken alone or in combination with one another, and potentially combined with one and / or the other of the characteristics of the first series mentioned above, it can be provided that
    - the wedge came integrally with the cooling member; by this formulation is meant to cover the fact that the shim is in one piece with such or such part of the cooling member, that is to say that the separation of the shim and the cooling member cannot be done without destruction of one and / or the other; therefore, the wedge is not an insert, separate from the cooling member and to be fixed elsewhere;
    - the shim is a separate part of the cooling member, for
    0 example made of an elastic material, in particular a plastic foam;
    - The wedge is arranged between two dissipation walls of the same fin, capable of coming into contact with at least one of the two walls during the elastic reconciliation of this fin with another fin;
    - the wedge came in one piece with a dissipation wall of one of the fins and extending towards the other fin; we understand that in this case, the wedge extends in orthogonal projection from the plane defined by the dissipation wall;
    - the wedge came integrally with the connection portion of one of the fins;
    - The wedge has the shape of a finger extending the connection portion to extend between two fins or between two dissipation walls of the same fin: by finger, we mean a protrusion projecting from the connection portion which has dimensions smaller than those of the connection portion, in particular along the transverse direction defining the direction of the series of fins and connection portions;
    - the shim extends the connection portion from a lateral edge thereof, substantially parallel to the dissipation wall along which the shim extends;
    îo - the shim extends in a direction orthogonal to the plane defined by the connection portion of the associated fin, in particular by a fold with this connection portion, or else it extends in the plane defined by the connection portion associated fin;
    - the wedge is formed by a folded corner of the connection portion.
    The invention also relates to a motor vehicle headlamp comprising a light module as it has just been described, and in particular a headlamp comprising a housing and a closing glass defining a housing for receiving at least one light module.
    Other characteristics and advantages of the present invention will appear more clearly with the aid of the description and the drawings, among which:

    Figures 6 and 7 are steps of the process for obtaining by folding the cooling member of Figure 3; and îo - Figure 8 is a detail view of a cooling member according to a second embodiment of the invention.
    In the description which follows, a longitudinal, vertical and transverse orientation will be adopted, without limitation, according to the orientation traditionally used in the automobile and illustrated by the trihedron L, V, T of FIG. 2. In addition, the terms lower and upper must be interpreted in the light of the position of the light module in the motor vehicle when this module is in the normal position of use.
    FIG. 1 represents a light module 2 intended to be fixed in a
    0 housing (not shown) of a headlight of a motor vehicle.
    The module comprises a base 4 on which are attached at least one cooling member 6, a light reflector 8, and one or more light sources 10, consisting here of light-emitting diodes 10. The light source 10 is arranged opposite of the light reflector 8 so that the light rays emitted by the source are directed towards the latter so that it deflects them towards an optical element 12, here taking the form of a lens.
    We understand that, without departing from the context of the invention, we can propose a light module with an optical shaping system
    0 different from the one presented here, formed by the reflector and the lens.
    The light source 10 can be mounted on a printed circuit board 14, the assembly being supported by the base 4. The cooling member 6, the function of which is to dissipate the heat produced by the light source 10, is also arranged on this base 4, substantially in the vicinity of the light source 10. In FIG. 1, two cooling members have been illustrated arranged opposite one another, on either side of the defined plane by the base 4. In the following, only one cooling member will be illustrated and described but, symmetrically, two cooling members may be fixed to the base.
    îo It is understood that the base 4 has a mechanical support function for the light source 10 and for the cooling member 6 also and that it participates in the transfer of the heat produced by the light source in operation towards the member cooling 6, the shape of which is described below, allows the heat to be removed away from the light source.
    An embodiment has been illustrated in FIG. 2 in which the base 4 supports three light-emitting diodes and the cooling member 6.
    The base 4 has a substantially flat plate shape, with a first face 16 and an opposite second face 17. At a first longitudinal end of the base, fixing means are provided for
    0 immobilize the cooling member, while the opposite longitudinal end of the base may have a bevelled shape to form a cutting edge of the rays emitted by the source and deflected by the reflector.
    The cooling member 6 is fixed to the first longitudinal end of the base 4, so that a first part 18 of the cooling member 6 is without contact with the base 4. This particular configuration makes it possible to increase the surface exchange of the cooling member 6 with the surrounding air.
    The first face 16 is configured to receive the light source or sources 10 and the printed circuit board. In the example illustrated in the figure
    0 2, it is on this first face 16 that the cooling member 6 is fixed in the vicinity of the light source 10, but as may have been specified previously, provision may be made for a second cooling member to be fixed on the second face symmetrically to the first cooling member, or it can be provided that only one cooling member is provided, but fixed on the second face.
    The cooling member 6 comprises a fixing part 20 and a heat dissipating part 22. These two parts 20, 22 form a one-piece assembly, that is to say that they are made in a common part and that they cannot be separated without causing the rupture of one or the other.
    The cooling member is placed relative to the base so that the fixing part overlaps the base, to allow the provision of a layer of adhesive, forming a thermal interface, between the fixing part and the base, and so that the dissipating part 22 is partly without contact with the base 4.
    The cooling member is formed by folding a single sheet metal part, the folding in particular forming a bellows assembly for the heat dissipating part 22. The material used to obtain this sheet can in particular be aluminum .
    0 The cooling member 6 comprises a plurality of dissipation walls 23, connected in pairs to form a fin 24. These dissipation walls 23 are substantially parallel to each other. The cooling member comprises at least two fins and in the illustrated case, it comprises five fins respectively formed by two dissipation walls.
    Each dissipation wall and the fin that it contributes to form has a proximal part 26, turned towards the fixing part 20 and towards the base 4, and a distal part 28 forming a free end remote from the base. The proximal part 26 of each dissipation wall carries a portion
    0 connection 30 which extends substantially perpendicularly the wall ίο dissipation and which will be described in more detail below, all of the connection portions forming the fixing part 20. It can be seen that the proximal part has a height, c that is to say a dimension in the vertical direction, less than the height of the distal part, so that a shoulder 32 delimits these distal and proximal parts of the dissipation wall. It will be noted that the shoulder 32 is intended to abut against the thickness of the base 4 to facilitate the positioning and the maintenance of the cooling member 6 on the base 4.
    The cooling member takes the form of a sheet folded into several zones along substantially vertical bending axes AA, that is to say axes substantially perpendicular to the main direction of longitudinal elongation of the walls of dissipation, and substantially perpendicular to the extension plane defined by the first face 16 of the base 4. This succession of folding axes defines a series of consecutive fins along the transverse direction.
    In this plurality of folding zones, one can in particular distinguish first folds 33 connecting together two successive fins 24 at the level of the proximal end 26 of the dissipation walls 23 making them up, and second folds 34 connecting together two walls of
    0 dissipation of the same fin, at their distal end 28.
    The alternation of first fold and second fold thus defines a serpentine shape from a first dissipation wall 23a disposed at a transverse end of the cooling member to a second dissipation wall 23b disposed at a transverse end opposite of the cooling member.
    The plurality of fins juxtaposed in transverse series provides a large exchange surface with the surrounding air allowing the heat dissipated from the base 4 to the cooling member 6 to be quickly dissipated.
    0 In this plurality of fins 24 forming the dissipating part 22, one can observe two external fins 24a, 24b, arranged at each of the transverse ends of the cooling member and which here have a smaller longitudinal dimension than that of the other fins that 'they surround, as well as a central fin 24c.
    The dissipating part 22 is attached to the base 4 by means of the fixing part 20, formed by several connection portions 30 which are distinct from each other. These connection portions 30 each have a first fixing face 35 intended to be fitted against the base 4, and the arrangement in a transverse series of the connection portions, substantially in the same plane, arranges the connection portions in a strip. transverse fixing. The first fastening faces 35, visible in particular in FIG. 3, are fixed to the first face 16 of the base using an adhesion means, such as glue, preferably having advantageous thermal transfer properties.
    Each dissipation wall 23 is extended by a connection portion 30, which extends substantially perpendicular to this dissipation wall by being connected together by a fold 36. The two connection portions of the same fin are folded in the same direction so that a first connection portion 30a is folded to extend substantially between the two dissipation walls 23 of the same fin,
    0 between the proximal end and the shoulder 32 of the dissipation walls of this fin, and that a second connection portion 30b is folded to extend in the same direction between a dissipation wall of a fin and a wall dissipation of a neighboring fin. It can be seen in the figures that the central fin 24c differs from this arrangement so that its connection portions are bent in opposite directions, each away from the fin which carries them. In this way, the central fin defines a longitudinal axis of symmetry B-B of the cooling member, an equal number of connection portions being distributed on either side of this longitudinal axis of symmetry.
    0 Furthermore, the outer fins 24a, 24b differ from the other fins in that the second connection portion that they carry, that is to say the connection portion folded in the direction of the separation of the fin , carries first indexing means 38. These first indexing means can consist of orifices configured to cooperate with second indexing means carried by the base, and in particular pins 39. As may have been specified previously , the alignment of the pins 39 and the orifices of the first indexing means 38 can be obtained by means of a stress exerted on the fins of the cooling member. The elastic connection between the fins, obtained by the presence of the folding zones, allows the fins to come closer to one another, or at least to the dissipation walls of the same fin to get closer to each other.
    In order to ensure that the plane defined by the arrangement of the first fixing faces of the connection portions is perfectly plane, and thus to ensure a contact zone between the cooling member and the base which is of constant thickness to ensure in particular a homogeneity of heat exchange, provision is made according to the invention to have a shim 40 facing a part of a fin, in particular to avoid overlapping of the connection portions on each other.
    In what follows, a first embodiment will be described, with particular reference to FIGS. 3 to 7, in which the shim 40 is formed projecting from a connection portion 30. It is thus intended to equip the portions of connection, or at least at least one, of a shim configured to come into contact with a dissipation wall 23.
    Each connection portion has the shape of a rectangular element with a lateral edge 42 common with the dissipation wall, which corresponds at least in part with the fold 36, and two edges perpendicular to this lateral edge, one of which is an end edge. front longitudinal 44 facing the light source and a rear longitudinal end edge 46 facing the fins.
    The wedge 40 extends the connection portion 30 from the rear longitudinal end edge 46 so as to extend between two dissipation walls. In the illustrated embodiment, with the exception of the central fin 24c, each fin 24 carries a shim 40, projecting from the first connection portion 30a carried by the fin, that is to say the portion connection folded so as to extend between the two dissipation walls
    23 of the fin. It is therefore understood that the wedge 40 has the effect of pressing on a dissipation wall 23 inside the corresponding fin 24 when the plurality of fins is elastically deformed. Provision could be made to equip each connection portion with a shim, but in the case where only one connection portion of a fin is equipped, it will advantageously be provided that it is the first connection portion which is equipped with the shim , in particular to allow the external fins to be fitted with such a wedge, which must also carry the indexing means.
    The wedge 40 extends the connection portion and it came integrally with this connection portion, in the same plane defined by this connection portion. If it is possible to provide variants in which the shim is folded to extend substantially perpendicular to the plane defined by the associated connection portion, it is advantageous here to have an arrangement of the shim in the planar continuity of the connection portion, so that a folding zone is avoided which could weaken the wedge when it comes into
    0 stop against the dissipation wall.
    The wedge takes the form of a finger extending from the rear longitudinal end edge 46 of the connection portion, in line with the free lateral edge, that is to say the lateral edge opposite the common lateral edge. 42 defining the fold 36 between the connection portion 30 and the dissipation wall 23. As a result, the shim is not centered in the middle of the fin, between the two dissipation walls, but that it extends in the vicinity of one of the two dissipation walls, ready to come into contact with it as soon as the fins are elastically deformed.
    We understand that this wedge 40 avoids that the portions of
    0 connections 30 which are adjacent do not overlap or overlap with each other. The wedge 40 is intended to come into contact against a dissipation wall 23 of a fin 24 to limit the travel of the connection portion during the elastic bringing together of two fins between them.
    As may have been clarified, the cooling member is formed from a folded sheet. We will now describe a process for obtaining by folding the cooling member 6, with particular reference to Figure 5 in which there is shown a portion of the unfolded sheet, fold lines being shown to facilitate understanding of manufacturing steps. It is understood that the cooling member 6 is formed from a single piece of sheet metal 60, originally planar, of substantially longitudinal shape and delimited by two longitudinal edges 62.
    A first longitudinal edge 62a extends in a rectilinear manner, while the second opposite longitudinal edge 62b comprises cutouts 63 configured to form, after folding, the connection portions 30. At each transverse end of the unfolded sheet, a specific cutout 64 is made to form the connection portion carrying the first indexing means.
    The cutouts 63 take the form of two facing portions, substantially L-shaped, which extend projecting from the second longitudinal edge 62b and separated at their free end by a slot 65 parallel to
    0 the axis of the first folds 33. Notches 66 are formed at the junction of the second longitudinal edge and the base of each of the portions, to subsequently facilitate the folding of the connection portions.
    The zones corresponding to the first 33 and second 34 folds extend from one longitudinal edge 62 to the other.
    One carries out the successive formation of the fins one after the other, by placing a roller against the sheet at the level of the different zones and by folding the dissipation walls facing each other. After this first folding step, a series of fins was formed for each of which the cutouts 63 are still in the same plane as the dissipation walls 23.
    In FIG. 6, two dissipation walls 23 are illustrated parallel to one another, with a first dissipation wall 23a forming part of a first fin and a second dissipation wall 23b forming part of a second fin directly adjacent to the first fin. The two fins are joined by a first fold 33 in the vicinity of which the connection portions extend. Here we have a first connection portion 30a extending the first dissipation wall 23a and which carries a wedge finger 40, and a second connection portion 30b extending the second dissipation wall 23, without wedge. As has just been specified, the connection portions are at this stage in the plane defined by the dissipation wall which they extend respectively.
    The connection portions are then folded at the folds 36 to fold them down and arrange them substantially orthogonally to the dissipation wall which they extend respectively. As illustrated in FIG. 7, these connection portions are folded in the same direction, so that the first connection portion 30a carrying the shim extends between two dissipation walls of the same fin and that the second connection portion 30b, here without shim, extends between a dissipation wall of a fin and a dissipation wall of a second fin.
    0 The folding of the connection portions is facilitated by the presence of the notches, which define, when the cooling member is mounted, the shoulders 32 between the proximal part 26 and the distal part 28 of the dissipation walls 23.
    According to the invention, the connection portions 30 are configured to form a flat fixing surface to increase the contact surface with the base. Advantageously, the connection portions 30 are adjacent but do not overlap due to the presence of shims 40 which limit the movement of the fins 24 relative to each other when a transverse stress is exerted on them at time of the
    0 positioning of the cooling member on the base. This prevents plastic deformation of the connection portions 30, and ensures constant spacing between the fixing faces of the connection portions and the face of the base on which these connection portions are pressed, and therefore a constant thickness of adhesive. . Thus the heat transfer between the base 4 and the dissipating part 22 of the cooling member 6 is improved thanks to a homogeneous distribution of the adhesive.
    Variant embodiments may be provided without the context of the invention being changed, since shims are provided facing part of the fin, to come into contact with the latter when at least two fins are brought together elastically. As a nonlimiting example, it can be provided that:
    - the fins are formed of a single dissipation wall and that only first folds are provided;
    - the wedges extend in a direction perpendicular to the plane defined by the connection portions;
    - at least one shim has come integrally with a dissipation wall of one of the fins, extending towards a neighboring fin;
    - the shims are formed by an attached piece fixed on the connection portion or on the dissipation wall.
    FIG. 8 illustrates another alternative embodiment, according to which the wedge is produced by a fold 70 of a corner 72 of the connection portion, and in particular a corner facing a neighboring connection portion. In this way, the wedge does not extend in the plane defined by the connection portions and forms a stop at the overlap of these neighboring connection portions, the connection portion carrying the wedge being unable to slide under the connection portion in look of which extends the hold. According to the invention, the wedge is able to come into contact with part of the fin, namely the connection portion.
