    (54) LIGHT EMISSION SYSTEM.
    FR 3 056 703 - A1 (57) The invention relates to a light emission system (1) comprising:
    - a light source support (2) comprising a first cooperation member (213),
    - a printed circuit (3) fixed to the light source support (2) and comprising a connection system (5),
    a connection cable (7) comprising a connection socket (6), this connection socket (6) comprising a second cooperation member (62),
    According to the invention, the connection system (5), the support (2) and the socket (6) are arranged so that when the connection system (5) and the socket (6) are connected one at the other, the first (213) and the second (62) cooperation members cooperate together to form a fixed mechanical connection.
    LIGHT EMISSION SYSTEM
    The invention relates to a light emission system, in particular a light emission system of a motor vehicle light device. More particularly, the invention relates to cooperation members making it possible to provide the link between the constituent elements of the light emission system.
    Light emission systems are known that carry a light source of the light emitting diode (LED), laser, halogen or other type. In general, the light emission system comprises a support carrying the light source and cabling making it possible to supply and control said source.
    In the case of light emission systems carrying LEDs, a printed circuit board (PCB) is associated with the LED with the aim of supplying it with electricity, controlling it and monitoring its good functioning. A connection cable is connected to the printed circuit to bring the electric current and allow it to perform all of its functions.
    Commonly, the connection cable comprises a connection socket adapted to cooperate with a connection system electrically connected to the printed circuit. Since the printed circuit is generally fixed, by welding or by gluing, to the support, the connection cable, once connected to the printed circuit, is held linked to the support.
    However, the connection between the connection cable and the support, inter alia between the connection socket and the connection system presents a risk of disconnection. Indeed, the connection socket may be detached from the connection member due to vibrations, shocks or other factors weakening the cooperation between the socket and the connection member. The detachment of the connection cable causes the light source to turn off, which in some cases may cause accidents, for example when the light emission system is installed in a lighting device for a motor vehicle.
    An objective of the invention is to provide a light emission system reducing the risk, or even not presenting a risk, of detachment between the connection socket and the connection system over time, which makes it possible to secure more the electrical connection of the light emission system during its use.
    To this end, a first object of the invention is a light emission system comprising:
    a light source support comprising a first cooperation member, a printed circuit fixed to the light source support and comprising a connection system, a connection cable comprising a connection socket, this connection socket comprising a second cooperation member,
    According to the invention, the connection system, the support and the socket are arranged in such a way that when the connection system and the socket are connected to each other, the first and the second cooperation members cooperate together to form a fixed mechanical connection.
    The term fixed mechanical connection means a connection having no degree of freedom, in particular an installation connection according to the vocabulary used in the field of mechanics. Thus, thanks to the first and second cooperation members, the connection system and the socket, once connected to each other, are held together over time despite stresses from the outside, such as vibrations, shock or other. There is therefore less, if any, risk of detachment of the connection cable from the printed circuit, which makes it possible to ensure the proper functioning of the light supplied and controlled by said printed circuit during a long period of use. It also means that the light-emitting system is more secure, which avoids unintended light cuts, which can lead to accidents when the system is integrated into a lighting device in a motor vehicle.
    In the present document, the light source is for example an electroluminescent light source. Such a light source uses electroluminescence. Electroluminescence is an optical and electrical phenomenon during which a material emits light in response to an electric current passing through it, or to a strong electric field.
    The light emission system according to the invention can optionally include one or more of the following characteristics:
    the first and the second cooperative members are arranged so as to engage and block one with respect to the other by clipping; thus, it is easy to produce mechanical parts, structurally simple and inexpensive, which ensure cooperation by clipping one into the other;
    the first cooperation member comprises a hole and the second cooperation member comprises a lug, the lug and the hole being arranged so that when the connection system and the plug are connected to each other, the lug abuts against an edge of the hole; thus, the hole, being made in the support, is simple to make. In addition, this solution is economically advantageous since we do not need an additional part to cooperate with the lug carried by the connection socket. The light source support is cleverly exploited to provide a cooperative device compatible with the pin. Furthermore, during the assembly of the light source support, it suffices to place the lug against an edge of the hole to hold the connection system and the connection socket together, which makes it possible to increase the assembly rate, therefore the productivity of the production chain of the light emission system. Conversely, to dismantle the light emission system, it suffices to release the lug from the hole by a simple and practical gesture after which the light source support is detached from the connection cable and can be easily manipulated, for example during an operation to change an old medium with a new one;
    the lug extends in a first direction and it has a triangular section in the first direction; such a shape is easier to produce, in particular by molding.
    the first and second cooperation bodies have complementary forms to each other; thus, there is a better hold between the cooperation members, which further strengthens the fixed mechanical connection between them;
    a light source fixed directly or indirectly to the light source support and connected to the printed circuit;
    the light source support is a heat sink; for example, the heat sink is installed in a lighting device for a motor vehicle;
    according to the preceding paragraph, the heat sink comprises a plate of conductive material on which the printed circuit is fixed, the first cooperation member being formed by a through hole in said plate; by way of example, the through hole can be produced by laser cutting or by stamping, which are simple and rapid operations;
    the connection system comprises a body adapted to be connected to the printed circuit, and a connection member adapted to cooperate with the connection socket in a first direction. The body of the connection system is disposed at a distance from an edge of the hole so that the space between the body and the edge in the first direction forms a housing in which the second cooperation member is placed; thus, when the connection and the connection socket are plugged into each other, the second cooperation member is in abutment against the edge of the hole;
    according to the preceding paragraph, the distance between the body and the edge of the hole in the first direction may be substantially identical to the dimension of the second cooperation member in this same direction; the connection is thus adjusted and the risks of disconnection linked to vibrations are reduced;
    the printed circuit is fixed on a first face of the plate, the connection system being connected to the printed circuit so that a body of the connection system passes through the hole and projects from a second face of the plate, opposite to the first face and that a connection member of the connection system is located on the side of the second face and adapted to cooperate with the connection socket; in other words, the printed circuit is on one side of the support and the connection cable on the other; thus, the connection of the connection cable to the connection system or the separation of these two elements is carried out away from the printed circuit, which avoids contact with it and therefore has less risk of spoil it;
    the connection member and the connection socket are of the male / female type.
    The invention also relates to a vehicle light device comprising at least one light emission system according to the invention.
    This vehicle light device can be:
    a road lighting device, in particular a headlamp or a fog light;
    a signaling light, in particular: a stop light, a daytime running light (also called DRL for "Day Running Light"), a night position light, a direction indicator;
    an interior lighting device, namely the interior of the vehicle interior, in particular: a ceiling lamp or a wall lamp.
    The invention also relates to a vehicle comprising at least one light device according to the invention.
    Other characteristics and innovative advantages will emerge from the description below, provided for information and in no way limitative, with reference to the appended drawings, in which:
    Figure 1 shows a schematic perspective view of a light emission system according to an embodiment of the invention;
    Figure 2 and Figure 3 show a schematic perspective view respectively from above and below of a light source support to which is fixed a printed circuit, said light source support and said printed circuit being part of the system light emission according to Figure 1;
    4 shows a sectional view along IV-IV of the light emission system of Figure 1;
    FIG. 5 represents a detail view A of FIG. 4.
    FIG. 6 represents a lighting device comprising several light emission systems such as that illustrated in FIG. 1.
    Referring to Figure 1, a light emission system according to the invention, referenced 1, comprises a light source support 2 carrying a light source (not shown in Figure 1); a printed circuit 3, partially visible in this figure; a connection system 5 being electrically connected to the printed circuit;
    several connection cables 7 connected to the connection system 5 via a connection socket 6.
    In the example illustrated, the light emission system 1 is adapted to be installed in a light device of a motor vehicle. In this example, the light device is a projector.
    The light source support 2 is configured here to both support the light source and to dissipate the heat emitted by said source. Here the support 2 is therefore a heat sink.
    The light source support 2 comprises a first plate 21 extending in a horizontal plane defined by two orthogonal vectors X and Y. with X extending in a longitudinal direction F1 of the emission system 1 and Y extending in a transverse direction F2 of said system 1. The light source support 2 further comprises a second plate 22 belonging to a vertical plane defined by two orthogonal vectors Z and Y with the vector Z extending in a vertical direction F3 pointing from bottom to top of figure 1
    Unless otherwise indicated, the terms "high" and "low" or "upper" and "lower". as well as "before". " back ". and "transverse" refers to the orientation in which the light emitting system is intended to be arranged when the light device comprising it is mounted in a vehicle. In particular, the terms "front" and "rear" are defined with respect to the direction of light emission in the sense of light emission from the light device. This orientation is illustrated in Figure 1.
    The first plate 21 of the support 2 has a first face 211 facing upwards and a second face 212 facing downwards. The first plate 21 further comprises a hole 213 passing through from the first face 211 to the second face 212. As illustrated in FIG. 2. the hole 213 may have a rounded rectangular shape, elongated in the transverse direction F2. This hole is called hereinafter: oblong hole. Furthermore, the first plate 21 comprises a raised base 41 projecting from the second face 212. A light source 4. fixed on the raised base 41. is at the same height of the printed circuit 3. which facilitates establishment of the electrical connection between these two elements. In addition, the light source 4 is in direct contact with the plate 21, which allows better dissipation of the heat emitted by said source.
    In the example illustrated, cooling fins are positioned at the front of the first plate 21. They consist of two lateral fins 217, 218 and a front fin 219. These cooling fins extend vertically from the first face 211.
    The printed circuit 3, which has the function of controlling and supplying the light source 4, is fixed to the second face 212 of the first plate 21. The printed circuit 3 is arranged so as to completely close the lower opening 215 of the hole 213 on the side of the second face 212 as shown in FIG. 3.
    In the same figure, the printed circuit 3 is fixed to the first plate 21 by screwing. As a variant, the printed circuit 3 can be fixed by gluing or by welding, the methods known to a person skilled in the art.
    As for the second plate 22 of the support 2, it comprises two lateral fins 221, opposite one another and extending towards the rear in the longitudinal direction F1.
    With reference to FIGS. 2 and 3, the second plate 22 also includes through openings 222 able to receive fastening members for the light reflector in order to block the movement of vertical and / or transverse translation of the light emission system 1. When the light source support 2 is installed on the reflector, a front face 223 of the second plate 22 is opposite a rear wall of the reflector.
    The light source support 2 comprising the first horizontal plate 21 and the second vertical plate 22 is obtained by a succession of steps comprising for example:
    a cutting step, a drilling step to form the oblong hole 213, the through holes 222, a stamping step to form the raised base 41, a first folding step to form fins of each of the plates, and a step second fold to form the first and second plates.
    Note that the first and second folding steps can be reversed.
    By way of example, the light source support 2 is produced from a metal plate, this material giving it high rigidity and good thermal conductivity.
    As can be seen in Figure 1, the connection system 5 is electrically connected to the printed circuit 3 by suitable members which will be detailed later in the description.
    The connection system 5 comprises a body 51 carrying connection members 52, illustrated in Figures 4 and 5 (but not shown in Figure 1). The connection members 52 are configured to cooperate with the connection socket 6 so as to establish an electrical connection between the socket 6 and the connection system 5. The body 51 of the connection system 5, being connected to the printed circuit 3, passes through the hole 213 and projects vertically from the first face 211. The connection members 52 are placed on the side of the first face 211 while the printed circuit 3 is located on the side of the second face 212.
    Several connection cables 7 are electrically connected to the connection system 5 via the connection socket 6. The connection cables 7 are connected to a control unit (not shown) which supplies electricity and which analyzes data to ensure the correct operation and to control the correct lighting of the light source. The cables 7 are thus adapted to ensure the electrical supply and the flow of information between the printed circuit and the control center.
    With reference to FIG. 4 and to FIG. 5, the connection socket 6 and the connection system 5 are connected to each other. The light source
    4, carried by the reception base 41, is located at the front of the light emission system 1. In the example illustrated, the light source 4 is electrically connected to the printed circuit 3 by soldered wires 42. Of course, there are other means known to those skilled in the art for establishing an electrical connection between the light source 4 and the printed circuit 3.
    The body 51 of the connection system 5 is connected to the printed circuit 3 by means of two metal pins 53 welded to the latter. As described above, the body 51 carries connection members located on the opposite side to that of the printed circuit 3. The connection members are, here, connection pins 52 extending backwards in the longitudinal direction F1. The connection pin 52, visible in FIGS. 4 and 5, is engaged in a housing 61 corresponding to the connection socket 6. The connection system 5 and the socket 6 as described are of the male / female type. Alternatively, the connection system 5 has housings while the connection socket 6 has connection pins.
    In the example illustrated, the connection socket 6 further comprises a lug 62 fixed to the bottom wall 65 of the connection socket 6. The lug 62 extends from a front face 64 of the connection socket 6 towards the 'rear, in a first direction A which is here parallel to the longitudinal direction F1. The section of the lug in the first direction A is substantially triangular with a large base 63 located at the rear.
    Referring to Figure 5, the body 51 of the connection system, fixed to the printed circuit, is located at a distance from a rear edge 216 of the hole 213 so as to leave sufficient space to fully accommodate the lug 62 between the edge rear 216 and the body 51, and so that the large base 63 of the lug abuts against the rear edge 216 of the hole 213.
    In this example, the distance d in the first direction A between the body 51 and the rear edge 216 corresponds to the dimension of the lug 62 defined in the same direction.
    When the socket 6 is connected to the connection system 5, the lug 62 and the hole 213 cooperate with each other to form a fixed connection having no degree of freedom of movement. Consequently, this connection prevents the rearward movement of the connection socket 6 and therefore the detachment thereof from the connection system 5 when the light-emitting system 1 is subjected to vibrations.
    In the example illustrated in FIG. 6, and in a nonlimiting manner, the light device comprises three reflectors 83, on each of which are arranged respectively a light source support 2 of the light emission system 1 according to the invention (the light system connection and connection cables are not shown for clarity). In FIG. 6, only the position of the reflectors is identified by the reference 83, the reflective surfaces of the reflectors not being visible.
    The arrangement of each light emitting system 1 on the corresponding light reflector 83 is designed so that the emitted light is directed towards the front of the vehicle by creating or participating in the generation of a light beam , in particular a light beam meeting the standards imposed in the automotive field.
    For each light source support 2, the corresponding reflector 83 is arranged so as to allow engagement of the first plate 21 in two horizontal grooves 81 arranged on either side of the first plate 21 until the latter is stopped by a front stop 84 of the reflector 83. At the end of the engagement, the second plate 22 is in abutment against a rear wall of the reflector 83 and fixing and / or positioning members 82 are engaged in the openings 222 of the second plate 22 in order to prevent the vertical and transverse displacement of the support 2.
    In order to reinforce the fixing of the support 2 on the reflector 83, the fixing and / or positioning members 82 comprise a screw so as to screw the second plate 22 to the rear wall of the reflector.
    Once the light source support 2 is installed, the light source is facing a reflecting surface of the corresponding reflector 83 making it possible to direct the light emitted forward and to create a light beam or part of a light beam with a given photometry. For example, a first assembly formed by a first light source support 2 and the associated reflector 83 allows the generation of a driving beam, a second assembly formed by a second light source support 2 and the associated reflector 83 allows the generation of part of a low beam, in particular its lower part, a third assembly formed by a third light source support 2 and the associated reflector 83 allows the generation of another part of the low beam, in particular its oblique part.
