Definitions
- the present invention relates to the field of light devices, in particular of a motor vehicle, in which a light source is positioned relative to an optical unit.
- the invention relates to a light module in which this positioning is ensured by means of referencing the support of this source cooperating with means of referencing the optical unit. More particularly, these referencing means are pins and orifices in which these pins are inserted.
- referencing means benchmarks to guarantee a determined positioning in at least one direction in space.
- the light source support and the optical unit are produced separately, sometimes by different manufacturers, and therefore have certain manufacturing tolerances, particularly with regard to the positioning of holes and orifices. In the event of a slight offset, the risk is that assembly will be difficult, if at all.
- a known solution is to make the referencing pin with a diameter which is sufficiently smaller than that of the corresponding orifice, so that a clearance is present around the pin, between the latter and the edges of the 'orifice.
- a technical problem which the present invention aims to solve is therefore to improve the precision of the positioning of the light source relative to the optical unit, while guaranteeing an assembly of the support to the optical unit.
- a first object of the invention is a light module for a lighting and / or signaling device of a motor vehicle, comprising:
- a referencing system comprising at least one referencing pin inserted in a referencing orifice, the support being provided with one of the referencing pawn and the referencing orifice, and the optical unit being provided with the other among the referencing pin and the referencing orifice the or at least one of the referencing pins comprising two opposite parts, one of the parts, known as the rigid part, being more rigid than the other of the parts, called flexible part.
- the flexible part may be deformed to allow the insertion of this pin in this orifice, the rigid part ensuring the guide of the pin in the orifice.
- the flexible part therefore allows a slight clearance during assembly, to guarantee that it is done more easily.
- the flexible part is in contact with the orifice, thus making it possible to limit or even eliminate the play.
- the positioning is more precise and less subject to variations during assembly of the module in the lighting and / or signaling device or when using the vehicle.
- the flexible part is elastic and arranged so as to press the rigid part against an edge of the referencing orifice; this removes the game completely while ensuring mounting travel and more precise positioning;
- the or at least one of the referencing pawns is a split pawn comprising a slot separating said two parts from one another; it’s a simple way to make a pawn in two parts, especially by molding or machining;
- the rigid part comprises a reinforcing protuberance, fixed to the portion of the optical unit from which the corresponding referencing pin projects and is arranged so as to oppose a force in a direction transverse to the slot, in particular perpendicular to slot ; guidance by the rigid part is thus improved by strengthening it;
- the reinforcing protuberance has a first rigid support zone allowing referencing in a direction orthogonal to the support, in particular in a vertical direction; with the same element, two functions are carried out, thus simplifying the production of the referencing system;
- the light module comprises at least two split reference pins whose slots are aligned in an alignment direction; this allows simple referencing perpendicular to the alignment direction;
- the light module comprises at least three referencing pins, a third split referencing pin being aligned at a distance from the alignment direction; this ensures isostatism in two orthogonal directions;
- the third referencing piece is also a split piece, the slot of which is directed perpendicular to said alignment direction; positioning accuracy is improved, while allowing travel simplifying assembly;
- the flexible part of or at least one of the referencing pins is a leaf spring arranged so that its stress increases when it approaches the rigid part; it's a simple way to press the rigid part against the edge of the hole; this leaf spring can be an insert, in particular made of metal;
- the or at least one of the referencing pins is bi-material, in particular obtained by bi-injection, the rigid part being in a first material and the flexible part being in a second material; it is an alternative way of making both parts;
- the second material is more flexible than the first material, and possibly elastic;
- the first material is polycarbonate (PC) and the second material is silicone;
- the light module includes several reference pins; positioning is improved;
- the light module comprises at least at least three referencing pins arranged so as to produce an isostatism in three transverse directions, in particular orthogonal directions, between them; positioning is further improved;
- the rigid part comprises a first rigid support zone pressed against a portion of the one which, among the optical unit or the support, comprises the corresponding referencing orifice, this portion being distinct from the edge or edges of this orifice; this makes it possible to carry out a referencing in a direction different from that of the referencing between the rigid part and the edge of the orifice; in particular in the case of the protuberance, the latter can extend between the base and a vertex of this protuberance, this vertex comprising the first support zone;
- the light module may include three referencing pins each having a first support area; the first three support zones thus define a referencing plane, allowing referencing in a direction perpendicular to this plane;
- the optical unit comprises one or a plurality of collimators, a cut-off member and an output member arranged so as to shape the light rays emitted by the light source so as to form a cut-off beam
- the monoblock optical part comprising the collimator (s)
- the optical unit may comprise a single-piece optical part comprising one or a plurality of collimators, a cut-off member and an output member arranged so as to shape the light rays emitted by the light source so as to form a beam cut-off, in particular a passing beam; positioning accuracy helps minimize risks of stray rays, which is particularly important in the context of a cut-off beam and in particular with a single piece;
- the referencing pin (s) and / or the rigid part of the referencing pin (s) came integrally with said one-piece optical part, the support comprising the referencing orifice (s); precise positioning of the support relative to the optical unit can thus be achieved;
- the referencing pin or pins are arranged around the or the plurality of collimators
- the support is a printed circuit board and has the referencing orifice (s), the optical unit presenting the referencing pin (s); the optical unit can for example comprise the one-piece optical part;
- the light source is a light emitting diode;
- the referencing orifices and / or the referencing pins are arranged in such a way that:
- the referencing pins have a first clearance with the edges of the corresponding referencing orifices
- the referencing pins are either on either side in contact with the edges of the corresponding referencing orifices, or have a second clearance with the edges of the corresponding referencing orifices, the first game being greater than the second game;
- the first set may be on each side of the lateral ends of the slot
- the referencing orifice (s) are oblong; in particular, in the case of split referencing pins, the referencing orifice (s) may have a greater width in a direction parallel to the slot than in a direction transverse thereto.
- Another object of the invention is a vehicle lighting and / or signaling device comprising a light module according to the invention.
- the invention also relates to a vehicle comprising a lighting and / or signaling vehicle according to the invention, in particular connected to the power supply of the vehicle.

- Figure 6 shows the light module of Figure 5, in rear perspective and from above;
- FIGS. 7a and 7b respectively represent a referencing pawn according to the prior art and an example of referencing pawn according to the invention
- FIG. 8 represents a beam having an upper cut-off line.
- Figures 1 to 3 illustrate an example of an optical unit of a light module according to an exemplary embodiment of the invention.
- This optical unit is here a one-piece optical part 1.
- the light module is a vehicle headlight light module.
- the optical part 1 comprises a first plurality of collimators 2 "and a second plurality of collimators 2".
- Each of these collimators 2 ', 2 ” comprises an input diopter 2, intended to receive the light rays r1, r2, r3 emitted by a light source 21, 22, intended to be placed here opposite and close from the free end of the corresponding collimator 2 ', 2 ”, at the top while lighting down in this example.
- the light source is a light-emitting diode, also called LED 21.
- the first plurality of collimators here comprises two collimators 2 ', which are each optically coupled to a reflection member 3, which is itself optically coupled to a breaking member 4, itself coupled to an output member 5. These different elements are therefore coupled together and arranged so as to shape the light rays emitted by the light sources 21 so as to form a cut-off beam.
- Each collimator 2 ’ is arranged to send, here by refraction and total internal reflection, the light rays r1, r2, r3 emitted by the LED 21, in a more concentrated beam, in the direction of the reflection member 3.
- This reflecting member 3 is here a diopter arranged so as to reflect by total internal reflection these rays r1, r2, r3 towards the breaking member 4, more particularly towards the stop 4a of this breaking member 4.
- the reflecting member 4 can reflect these rays r1, r2, r3 towards a focal zone arranged at this stop 4a.
- This output diopter 5 is arranged so as to form a member for projecting the image of the edge 4a.
- the rays r1 which pass as close as possible to the edge 4a, without meeting the surface 4b of the folder, in particular at the level of a focal zone of the output diopter 5, are refracted by the output diopter 5 in a parallel manner to an optical axis O of the light module.
- Some of these downward refracted rays r2 are first reflected directly by the reflecting member 3 on the output diopter 5, passing over the stop 4a.
- Other rays r3 refracted downwards are first reflected by the reflection member 3 behind the stop 4a, and are therefore reflected by the folder 4, by total internal reflection, towards the output diopter 5 , also passing over stop 4a.
- This beam is the light beam emitted by the optical module.
- this beam has an upper cut-off line L, as illustrated in FIG. 8.
- This cut-off line L corresponds to the image of the edge 4a, which therefore forms the cut-off edge of the folder 4, the radii being sent to the highest on the cut-off line (rays r1) or below (rays r2, r3).
- this beam is a central portion of a passing beam. It can be observed that the stop 4a indeed has an oblique portion and two horizontal portions on either side of this oblique portion, corresponding to the shape of the cut line L.
- the second plurality of collimators here comprises five 2 ”collimators which are each optically coupled from upstream to downstream to a 3” reflecting member, a 4 ”breaking member and a 5” outlet member, arranged so as to shape the light rays emitted by the light source so as to form a beam with horizontal cutoff, according to the same principle as described in FIG. 3.
- the difference is that here the cutoff stop 4a ”is in a horizontal plane.
- the central portion and the beam with horizontal cut are emitted at the same time so as to form a passing beam.
- the dioptres forming the input diopter 2 of the collimators 2 ', 2 ”, the reflection members 3, 3”, the bending machines 4, 4 ”forming the cut-off members and the output diopters 5, 5” therefore make it possible by their arrangement for shaping the beam so that it corresponds to a passing beam. These diopters therefore form the active surfaces of the optical part 1.
- the optical part 1 is provided with referencing pins 30.
- the reference pins 30 are three in number and include two opposite parts:
- the three reference pins 30 are split pins comprising a slot, not shown, separating these two parts 31, 32 from one another.
- Each of these referencing pins 30 projects, here upwards, from a portion of the optical part 1, this portion being hereinafter called base 35.
- the rigid part 31 can, as here, have a reinforcement protrusion 34.
- This reinforcement protrusion 34 can extend between said base 35 and a top 36 of this protuberance 34.
- This vertex 36 can, as here, form a first rigid support zone 36 allowing referencing in a direction orthogonal to the support, here in a vertical direction Z, as will be explained below.
- the first three rigid support zones 36 are here flat and coplanar with one another. They therefore form a referencing plan passing through these support zones 36 thus allowing a referencing according to a displacement along a direction perpendicular to this referencing plane. They therefore allow here a referencing of a support in a vertical direction Z, when this support is mounted in abutment against these bearing zones 36.
- the reinforcement protrusions 34 can be connected to the respective reference pins 30 over their entire lengths and thus stiffen the respective reference pins 30 according to a movement going from the flexible part 32 towards the rigid part 31.
- these referencing pins 30 form with referencing orifices 25 a system for referencing a support 20 of the light sources 21, 22 on the optical part 1, in order to correctly position the LEDs 21, 22 with respect to the input dioptres 2 and the collimators 2 ', 2 ”.
- the referencing pins 30 have come in one piece with the optical part 1, the support 20 comprising the referencing orifices 25.
- the support 20 is a printed circuit board, on which the LEDs 21, 22 are positioned and fixed. It is therefore easier to produce the reference orifices 25 on this card and to produce the reference pins 30 on optical part 1.
- the flexible part 32 can be elastic. In this example, this is achieved by means of the slot 33.
- the slot 33 allows the flexibility of the flexible part 32, in particular towards the rigid part 31.
- the rigidity of the latter is reinforced by the reinforcement protrusion 34.
- FIG. 7a illustrates a referencing pin P according to the prior art.
- the latter cooperates with a referencing orifice R of a light source support S.
- a clearance J is provided between the lateral edges of the referencing pin P and the edge of this referencing orifice R.
- FIG. 7b which illustrates a referencing pin 30, such as those of the optical part illustrated in FIGS. 1 to 6, the referencing pin 30 is housed in the referencing orifice 25 of the support 20, the rigid part 31 being against the edge 26 of the reference orifice 25.
- the slot 33 can be arranged so as to extend in depth along a longitudinal axis of the referencing pin 30.
- the slot 33 can extend through the referencing orifice 25 and beyond the referencing orifice 25, moving away from the free end of the referencing pin 30.
- the flexibility of the flexible part 32 allows it to be brought closer to the rigid part 31. This movement allows that in the event of misalignment of the pin and the reference orifice 30, 25, the flexible part 32 folds into the slot 33, allowing the referencing pin 30 to pass into the referencing orifice 25.
- this flexible part 32 will generate a restoring force, so that the flexible part 32 will exert a push on the edge 26 of the referencing orifice 25 and move the referencing pin 30 towards the part of the edge which is opposite the rigid part 31.
- This rigid part 31 thus ensures the accuracy of the referencing.
- This clearance 27 can even be zero, in particular with the flexible part 32 in stress against the edge of the orifice and exerting a thrust pressing the rigid part 31 against the edge 26 of the orifice 25.
- this thrust is exerted in a direction transverse to the slot 33.
- the support 20 is pressed in with its face carrying the LEDs 21, 22 bearing against the first support area 36.
- this first rigid support area 36 is pressed against a portion of the support 20 adjacent to the edge 26 of the corresponding reference orifice 25.
- the optical part 1 comprises three referencing pins
- the support 20 is supported on the first three support zones 36, which are coplanar with each other, and are therefore included in a plane A, here horizontal, symbolized by the dotted rectangles in FIG. 4.
- This allows positioning of the support 20 according to this plane A and therefore an assembly with vertical referencing. In fact, this allows precise positioning with respect to a displacement in the vertical direction Z.
- the first support zones 36 form a stop in the vertical direction Z.
- the slots 33 of the two front reference pins 30, arranged at the top of these figures, are aligned in an alignment direction B, here parallel to a transverse direction Y.
- the front referencing orifices 25 are slightly oblong, so that these front referencing pins 30 have play at each lateral end of their slots 33 and no play perpendicular to and on either side thereof. .
- a transverse play is allowed according to this alignment direction B.
- the movement of the corresponding flexible parts 32 allows assembly with less risk and allows the plating of the two rigid parts.
- the third referencing pin 30, here at the rear, is at a distance from the alignment direction B, therefore from the line passing through the slots 33 of the front referencing pins 30.
- this rear referencing pin 30 is arranged so as to be aligned with a longitudinal straight line C perpendicular to the alignment direction B.
- the movement of the flexible part 32 of this rear referencing pin 30 allows the plating of the corresponding rigid part 31 against the edge of the referencing orifice 25, therefore a plating along a point of this longitudinal straight line C.
- this point thus forms a limit of displacement according to a transverse displacement of the support 20, and therefore forms a transverse referencing between the optical part 1 and the support 20.
- rear referencing orifice 25 is open on the rear side so as to allow longitudinal play, so as to facilitate the movement of the flexible parts 32 of the front referencing pins 30.
- referencing pins 30 are arranged around the pluralities of collimators 2 ’, 2”, or even adjacent to certain collimators 2 ’, as can be seen in FIG. 7b.
- such an isostatic referencing can be obtained with three referencing pawns, at least one of which differs from the preceding referencing pawns in that the flexible part differs in that it is formed by a spring leaf, in particular made of metal.
- This blade can be planted or fitted into the referencing pin, the blade being able to be moved towards the rigid part by being put under elastic stress.
- such an isostatic referencing can be obtained with three referencing pawns, at least one of which differs from the pawns of referencing 30 previous in that the rigid part is made of a first material, in particular PC, and the flexible part is made of a second material, in particular silicone, thus allowing elastic deformation with increase in stress when the part flexible is compressed towards the rigid part.
