Description

La présente invention se rapporte au domaine des dispositifs lumineux, notamment de véhicule automobile, dans lesquels une source de lumière est positionnée par rapport à une unité optique.The present invention relates to the field of light devices, in particular motor vehicle devices, in which a light source is positioned relative to an optical unit.

En particulier, l'invention a trait à un module lumineux dans lequel ce positionnement est assuré par des moyens de référencement du support de cette source coopérant avec des moyens de référencement de l'unité optique. Plus particulièrement, ces moyens de référencement sont des pions et des orifices dans lesquels sont insérés ces pions.In particular, the invention relates to a light module in which this positioning is provided by means for referencing the support of this source cooperating with means for referencing the optical unit. More particularly, these referencing means are pins and orifices in which these pins are inserted.

Les documents JP 2015 079614 A , US 2015/093179 A1 , FR 2 698 738 A1 montrent l'utilisation de pions de référencement lors du positionnement d'une pièce par rapport à une autre.The documents JP 2015 079614 A , US 2015/093179 A1 , FR 2 698 738 A1 show the use of referencing pins when positioning one part relative to another.

Par « référencement », on entend des repères permettant de garantir un positionnement déterminé selon au moins une direction dans l'espace.By "referencing" is meant markers making it possible to guarantee a determined positioning according to at least one direction in space.

Il est connu d'assurer un référencement selon trois directions orthogonales entre elles par insertion de pions dans des orifices afin d'assurer un positionnement précis. Comme le positionnement est selon ces trois directions, une seule position est théoriquement possible. Par conséquent en l'absence de jeu, le support doit être positionné précisément avant montage sur l'unité optique si l'on veut que le support s'assemble.It is known to provide referencing in three mutually orthogonal directions by inserting pins into orifices in order to ensure precise positioning. As the positioning is according to these three directions, only one position is theoretically possible. Consequently, in the absence of play, the support must be positioned precisely before assembly on the optical unit if the support is to be assembled.

Cependant, le support de source de lumière et l'unité optique sont produits séparément, parfois par des fabricants différents, et présentent donc certaines tolérances de fabrication, notamment quant au positionnement des trous et des orifices. En cas de léger décalage, le risque est que l'assemblage se fasse difficilement, voire pas du tout.However, the light source support and the optical unit are produced separately, sometimes by different manufacturers, and therefore have certain manufacturing tolerances, in particular as regards the positioning of the holes and the orifices. In the event of a slight offset, the risk is that the assembly will be difficult, if at all.

Pour éviter cela, une solution connue est de réaliser le pion de référencement avec un diamètre suffisamment inférieur à celui de l'orifice correspondant, de manière à ce qu'un jeu soit présent autour du pion, entre celui-ci et les bords de l'orifice.To avoid this, a known solution is to make the referencing pin with a diameter sufficiently smaller than that of the corresponding orifice, so that a clearance is present around the pin, between it and the edges of the 'orifice.

Si cela permet de garantir un montage, un inconvénient est que ce jeu subsiste une fois le support assemblé à la pièce optique. La conséquence est que l'on perd en précision dans le positionnement de la source de lumière par rapport à l'unité optique, en particulier lors de l'utilisation du véhicule. Par conséquent, on perd également dans la qualité du faisceau émis par le module lumineux.If this makes it possible to guarantee assembly, a drawback is that this clearance remains once the support is assembled to the optical part. The consequence is that we lose precision in the positioning of the light source with respect to the optical unit, especially when using the vehicle. Consequently, the quality of the beam emitted by the light module is also lost.

Un problème technique que vise à résoudre la présente invention est donc d'améliorer la précision du positionnement de la source de lumière par rapport à l'unité optique, tout en garantissant un assemblage du support à l'unité optique.A technical problem which the present invention aims to solve is therefore to improve the precision of the positioning of the light source with respect to the optical unit, while guaranteeing assembly of the support to the optical unit.

A cet effet, un premier objet de l'invention est un module lumineux pour un dispositif d'éclairage et/ou de signalisation d'un véhicule automobile, tel que défini par la revendication 1 et comprenant :

  • au moins une source de lumière montée sur un support,
  • une unité optique destinée à coopérer avec la source de lumière pour former un faisceau lumineux,
  • un système de référencement comprenant au moins un pion de référencement inséré dans un orifice de référencement, le support étant pourvu de l'un parmi le pion de référencement et l'orifice de référencement, et l'unité optique étant pourvue de l'autre parmi le pion de référencement et l'orifice de référencement ;
le ou au moins l'un des pions de référencement comprenant deux parties en vis-à-vis, l'une des parties, dite partie rigide, étant plus rigide que l'autre des parties, dite partie souple.To this end, a first object of the invention is a light module for a lighting and/or signaling device for a motor vehicle, as defined by claim 1 and comprising:
  • at least one light source mounted on a support,
  • an optical unit intended to cooperate with the light source to form a light beam,
  • a referencing system comprising at least one referencing pin inserted into a referencing orifice, the support being provided with one of the referencing pin and the referencing orifice, and the optical unit being provided with the other of the referencing pin and the referencing orifice;
the or at least one of the referencing pins comprising two parts facing each other, one of the parts, called the rigid part, being more rigid than the other of the parts, called the flexible part.

Ainsi lors de l'assemblage du support à l'unité optique, en cas de décalage entre l'orifice et le pion de référencement avec lequel il coopère, la partie souple pourra se déformer pour permettre l'insertion de ce pion dans cet orifice, la partie rigide assurant le guidage du pion dans l'orifice. La partie souple permet donc un léger débattement à l'assemblage, permettant de garantir que celui-ci se fasse plus facilement. Une fois insérée, la partie souple est en contact avec l'orifice, permettant ainsi de limiter, voire de supprimer le jeu. De ce fait, le positionnement est plus précis et moins sujet à des variations lors de l'assemblage du module dans le dispositif d'éclairage et/ou de signalisation ou lors de l'utilisation du véhicule.Thus when assembling the support to the optical unit, in the event of a mismatch between the orifice and the referencing pin with which it cooperates, the flexible part may deform to allow the insertion of this pin into this orifice, the rigid part guiding the pin in the orifice. The flexible part therefore allows a slight movement during assembly, making it possible to guarantee that this is done more easily. Once inserted, the flexible part is in contact with the orifice, thus making it possible to limit or even eliminate play. As a result, positioning is more precise and less subject to variations when assembling the module in the lighting and/or signaling device or when using the vehicle.

Les figures 1 à 3 illustrent un exemple d'unité optique d'un module lumineux selon un exemple de réalisation de l'invention. Cette unité optique est ici une pièce optique 1 monobloc.THE figures 1 to 3 illustrate an example of an optical unit of a light module according to an example embodiment of the invention. This optical unit is here a one-piece optical part 1.

Dans cet exemple, le module lumineux est un module lumineux de projecteur de véhicule.In this example, the light module is a vehicle headlight light module.

La pièce optique 1 comprend une première pluralité de collimateurs 2' et une deuxième pluralité de collimateurs 2". Chacun de ces collimateurs 2', 2" comprend un dioptre d'entrée 2, destiné à recevoir les rayons lumineux r1, r2, r3 émis par une source lumineuse 21, 22, destinée à être placée ici en vis-à-vis et proche de l'extrémité libre du collimateur correspondant 2', 2", en haut en éclairant vers le bas dans cet exemple.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 dioptre 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 to the free end of the corresponding collimator 2', 2", at the top while illuminating downwards in this example.

Dans cet exemple, la source lumineuse est une diode électroluminescente, encore appelée LED 21.In this example, the light source is a light-emitting diode, also called LED 21.

Ces rayons lumineux r1, r2, r3 entrent par réfraction dans les collimateurs 2', 2", donc dans la pièce optique 1.These light rays r1, r2, r3 enter by refraction into the collimators 2', 2", therefore into the optical part 1.

La première pluralité de collimateurs comprend ici deux collimateurs 2', qui sont chacun couplés optiquement à un organe de réflexion 3, qui est lui couplé optiquement à un organe de coupure 4, lui-même couplé à un organe de sortie 5. Ces différents éléments sont donc couplés entre eux et agencés de manière à mettre en forme les rayons lumineux émis par les sources lumineuses 21 de manière à former un faisceau à coupure.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 cut-off 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.

Chaque collimateurs 2' est agencé pour envoyer, ici par réfraction et réflexion totale interne les rayons lumineux r1, r2, r3 émis par la LED 21, en un faisceau davantage concentré, en direction de l'organe de réflexion 3.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.

Cet organe de réflexion 3 est ici un dioptre agencé de manière à réfléchir par réflexion totale interne ces rayons r1, r2, r3 vers l'organe de coupure 4, plus particulièrement vers l'arrête 4a de cet organe de coupure 4. Par exemple, l'organe de réflexion 4 peut réfléchir ces rayons r1, r2, r3 vers une zone focale agencée au niveau de cette arrête 4a.This reflection member 3 is here an optical interface arranged so as to reflect by total internal reflection these rays r1, r2, r3 towards the switching device 4, more particularly towards the edge 4a of this switching device 4. For example, the reflection member 4 can reflect these rays r1, r2, r3 towards a focal zone arranged at this edge 4a.

Ces rayons r1, r2, r3 passent au niveau de cette arrête 4a de trois manières différentes, comme il sera expliqué ci-après, puis atteignent l'organe de sortie 5, ici le dioptre de sortie 5 de la pièce optique 1. Ils sortent ensuite de la pièce optique 1 par réfraction au travers du dioptre de sortie 5.These rays r1, r2, r3 pass at the level of this edge 4a in three different ways, as will be explained below, then reach the output member 5, here the output dioptre 5 of the optical part 1. They come out then of the optical part 1 by refraction through the exit diopter 5.

Ce dioptre de sortie 5 est agencé de manière à former un organe de projection de l'image de l'arrête 4a.This exit diopter 5 is arranged so as to form a member for projecting the image of the edge 4a.

Ainsi, les rayons r1 qui passent au plus près de l'arrête 4a, sans rencontrer la surface 4b de la plieuse, notamment au niveau d'une zone focale du dioptre de sortie 5, sont réfractés par le dioptre de sortie 5 de manière parallèle à un axe optique O du module lumineux.Thus, the rays r1 which pass as close as possible to the edge 4a, without encountering the surface 4b of the bender, in particular at the level of a focal zone of the exit diopter 5, are refracted by the exit diopter 5 in a parallel manner. to an optical axis O of the light module.

En revanche, les rayons r2 et r3 qui passent au-dessus de cet arrête 4a seront réfractés vers le bas par le dioptre de sortie 5.On the other hand, the rays r2 and r3 which pass above this edge 4a will be refracted downwards by the exit diopter 5.

Certains de ces rayons r2 réfractés vers le bas, sont d'abord réfléchis directement par l'organe de réflexion 3 sur le dioptre de sortie 5, en passant au-dessus de l'arrête 4a. D'autres rayons r3 réfractés vers le bas, sont d'abord réfléchis par l'organe de réflexion 3 en arrière de l'arrête 4a, et sont donc réfléchis par la plieuse 4, par réflexion totale interne, vers le dioptre de sortie 5, en passant également au-dessus de l'arrête 4a.Some of these rays r2 refracted downwards are first reflected directly by the reflector 3 on the exit diopter 5, passing above the edge 4a. Other rays r3 refracted downwards are first reflected by the reflection member 3 behind the edge 4a, and are therefore reflected by the bender 4, by total internal reflection, towards the exit diopter 5 , also passing over stop 4a.

L'essentiel, voire la totalité, des rayons r1, r2, r3 participe donc à la formation du faisceau sortant de la pièce optique 1. Ce faisceau est le faisceau lumineux émis par le module optique.Most, or even all, of the rays r1, r2, r3 therefore contribute to the formation of the beam emerging from the optical part 1. This beam is the light beam emitted by the optical module.

Par ailleurs, ce faisceau présente une ligne de coupure L supérieure, comme illustré en figure 8. Cette ligne de coupure L correspond à l'image de l'arrête 4a, qui forme donc le bord de coupure de la plieuse 4, les rayons étant envoyés au plus haut sur la ligne de coupure (rayons r1) ou en dessous (rayons r2, r3).Furthermore, this beam has an upper cut-off line L, as illustrated in figure 8 . This cut line L corresponds to the image of the edge 4a, which therefore forms the cut edge of the folder 4, the rays being sent to the highest point on the cut line (rays r1) or below (rays r2 , r3).

Ici ce faisceau est une portion centrale d'un faisceau de croisement. On peut observer que l'arrête 4a présente en effet une portion oblique et deux portions horizontales de part et d'autre de cette portion oblique, correspondant à la forme de la ligne de coupure L.Here this beam is a central portion of a dipped beam. It can be observed that the edge 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.

La deuxième pluralité de collimateurs comprend ici cinq collimateurs 2" qui sont chacun couplés optiquement d'amont en aval à un organe de réflexion 3", un organe de coupure 4" et un organe de sortie 5", agencés de manière à mettre en forme les rayons lumineux émis par la source lumineuse de manière à former un faisceau à coupure horizontale, selon le même principe que décrit en figure 3. La différence est qu'ici l'arrête de coupure 4a" est dans un plan horizontal.The second plurality of collimators here comprises five collimators 2" which are each optically coupled from upstream to downstream to a reflection member 3", a cut-off member 4" and an output member 5", arranged so as to shape the light rays emitted by the light source so as to form a beam with horizontal cut-off, according to the same principle as described in picture 3 . The difference is that here the cutting edge 4a" is in a horizontal plane.

La portion centrale et le faisceau à coupure horizontale sont émis en même temps de manière à former un faisceau de croisement.The central portion and the horizontal cut-off beam are emitted at the same time so as to form a passing beam.

Les dioptres formant le dioptre d'entrée 2 des collimateurs 2', 2", les organes de réflexion 3, 3", les plieuses 4, 4" formant les organes de coupure et les dioptres de sortie 5, 5" permettent donc par leur agencement de mettre en forme le faisceau de manière à ce qu'il corresponde à un faisceau de croisement. Ces dioptres forment donc les surfaces actives de la pièce optique 1.The diopters forming the input diopter 2 of the collimators 2', 2", the reflection members 3, 3", the benders 4, 4" forming the cut-off members and the output diopters 5, 5" therefore allow by their arrangement of shaping the beam to match a dipped beam. These diopters therefore form the active surfaces of the optical part 1.

On comprend donc l'importance du positionnement des LED 21, 22 par rapport à leurs collimateurs 2', 2" respectifs. En effet, en cas d'erreur de positionnement, les rayons r1, r2, r3 ne vont pas suivre le trajet pour lequel la pièce optique 1 a été conçue. On risque donc d'obtenir un faisceau non conforme à ce qui était souhaité.We therefore understand the importance of the positioning of the LEDs 21, 22 with respect to their respective collimators 2', 2". Indeed, in the event of a positioning error, the rays r1, r2, r3 will not follow the path to which the optical part 1 was designed. There is therefore a risk of obtaining a beam that does not conform to what was desired.

Ceci est d'autant plus important avec la première pluralité de collimateurs 2', afin d'éviter le plus possible d'avoir des rayons au-dessus de la ligne de coupure L, et donc d'éblouir les conducteurs des véhicules suivis ou venant en sens inverse.This is all the more important with the first plurality of collimators 2′, in order to avoid as much as possible having rays above the cut-off line L, and therefore dazzling the drivers of the vehicles followed or coming reverse.

Pour cela, la pièce optique 1 est munie de pions de référencement 30.For this, the optical part 1 is provided with referencing pins 30.

Comme illustré en figures 1 et 2 et 4 à 6, les pions de référencement 30 sont au nombre de trois et comprennent deux parties en vis-à-vis:

  • une partie rigide 31,
  • une partie souple 32, au sens qu'elle est moins rigide que ladite partie rigide 31.
As illustrated in figures 1 and 2 And 4 to 6 , the referencing pins 30 are three in number and comprise two facing parts:
  • a rigid part 31,
  • a flexible part 32, in the sense that it is less rigid than said rigid part 31.

Ici les trois pions de référencement 30 sont des pions fendus comprenant une fente, non représentée, séparant ces deux parties 31, 32 l'une de l'autre.Here the three referencing pins 30 are split pins comprising a slot, not shown, separating these two parts 31, 32 from each other.

Chacun de ces pions de référencement 30 fait saillie, ici vers le haut, depuis une portion de la pièce optique 1, cette portion étant appelée ci-après base 35.Each of these referencing pins 30 projects, here upwards, from a portion of the optical part 1, this portion being referred to below as base 35.

D'une manière générale selon l'invention, la partie rigide 31 peut, comme ici, présenter une protubérance de renfort 34. Cette protubérance de renfort 34 peut s'étendre entre ladite base 35 et un sommet 36 de cette protubérance 34.Generally according to the invention, the rigid part 31 may, as here, have a reinforcing protuberance 34. This reinforcing protuberance 34 can extend between said base 35 and a top 36 of this protrusion 34.

Ce sommet 36 peut, comme ici, former une première zone d'appui rigide 36 permettant un référencement selon une direction orthogonale au support, ici selon une direction verticale Z, comme il sera expliqué après.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.

Les trois premières zones d'appui rigide 36, donc celles de chaque pion de référencement 30, sont ici planes et coplanaires entre elles. Elles forment donc un plan de référencement passant par ces zones d'appui 36 permettant ainsi un référencement selon un déplacement le long d'une direction perpendiculaire à ce plan de référencement. Elles permettent donc ici un référencement d'un support selon une direction verticale Z, lorsque on monte ce support en appui contre ces zones d'appui 36.The first three rigid support zones 36, therefore those of each referencing pin 30, are here planar and coplanar with each other. They therefore form a reference plane 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 support zones 36.

Selon l'invention, comme ici, les protubérances de renfort 34 peuvent être reliées aux pions de référencement 30 respectifs sur toute leurs longueurs et rigidifier ainsi les pions de référencement 30 respectifs selon un mouvement allant de la partie souple 32 vers la partie rigide 31.According to the invention, as here, the reinforcing protuberances 34 can be connected to the respective referencing pins 30 over their entire lengths and thus stiffen the respective referencing pins 30 according to a movement going from the flexible part 32 towards the rigid part 31.

Comme on peut le voir en figures 4 à 6, ces pions de référencement 30 forment avec des orifices de référencement 25 un système de référencement d'un support 20 des sources lumineuses 21, 22 sur la pièce optique 1, afin de positionner correctement les LED 21, 22 par rapport aux dioptres d'entrée 2 et aux collimateurs 2', 2 ".As can be seen in figures 4 to 6 , 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 diopters 2 and 2', 2" collimators.

Ici, les pions de référencement 30 sont venus de matière avec la pièce optique 1, le support 20 comprenant les orifices de référencement 25.Here, the referencing pins 30 are integral with the optical part 1, the support 20 comprising the referencing orifices 25.

Dans cet exemple, le support 20 est une carte de circuit imprimé, sur laquelle sont positionnées et fixées les LED 21, 22. Il est donc plus facile de réaliser les orifices de référencement 25 sur cette carte et de réaliser les pions de référencement 30 sur la pièce optique 1.In this example, the support 20 is a printed circuit board, on which the LEDs 21, 22 are positioned and fixed. It is therefore easier to make the referencing holes 25 on this board and to make the referencing pins 30 on optical part 1.

Néanmoins, selon d'autres exemples de réalisation non représentés, on pourrait inverser en réalisant les pions de référencement sur le support et les orifices de référencement sur une pièce de l'unité optique. Par exemple, on pourrait appliquer un tel agencement dans le cas où le support est un radiateur et la pièce de l'unité optique un réflecteur.Nevertheless, according to other exemplary embodiments not shown, it could be reversed by making the referencing pins on the support and the referencing orifices on a part of the optical unit. For example, such an arrangement could be applied in the case where the support is a radiator and the part of the optical unit a reflector.

Selon l'invention, la partie souple 32 peut être élastique. Dans cet exemple, cela est obtenu au moyen de la fente 33.According to the invention, the flexible part 32 can be elastic. In this example, this is achieved by means of slot 33.

La fente 33 permet la flexibilité de la partie souple 32, en particulier vers la partie rigide 31.The slot 33 allows the flexibility of the flexible part 32, in particular towards the rigid part 31.

La rigidité de cette dernière est renforcée par la protubérance de renfort 34.The rigidity of the latter is reinforced by the reinforcing protrusion 34.

Cet agencement et ses effets sont expliqués ci-après au regard des figures 7a et 7b.This arrangement and its effects are explained below with regard to the figures 7a and 7b .

La figure 7a illustre un pion de référencement P selon l'art antérieur. Celui-ci coopère avec un orifice de référencement R d'un support S de source lumineuse. Pour éviter un risque de non assemblage de l'unité optique et de ce support, un jeu J est prévu entre les bords latéraux du pion de référencement P et le bord de cet orifice de référencement R.There figure 7a illustrates a referencing pawn P according to the prior art. This cooperates with a referencing orifice R of a light source support S. To avoid a risk of non-assembly of the optical unit and this support, a clearance J is provided between the side edges of the referencing pin P and the edge of this referencing orifice R.

En figure 7b, qui illustre un pion de référencement 30, tel que ceux de la pièce optique illustrée en figures 1 à 6, le pion de référencement 30 est logé dans l'orifice de référencement 25 du support 20, la partie rigide 31 étant contre le bord 26 de l'orifice de référencement 25.In figure 7b , which illustrates a referencing pin 30, such as those of the optical part illustrated in figures 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 referencing orifice 25.

Selon l'invention, comme ici, la fente 33 peut être agencée de manière à s'étendre en profondeur selon un axe longitudinal du pion de référencement 30. Notamment la fente 33 peut s'étendre au travers de l'orifice de référencement 25 et au-delà de l'orifice de référencement 25 en s'éloignant de l'extrémité libre du pion de référencement 30.According to the invention, as here, the slot 33 can be arranged so as to extend in depth along a longitudinal axis of the referencing pin 30. In particular the slot 33 can extend through the referencing orifice 25 and beyond the referencing orifice 25 away from the free end of the referencing pin 30.

Lors de l'assemblage, la flexibilité de la partie souple 32 permet un rapprochement de celle-ci de la partie rigide 31. Ce débattement permet qu'en cas de mauvais alignement du pion et de l'orifice de référencement 30, 25, la partie souple 32 plie dans la fente 33, laissant passer le pion de référencement 30 dans l'orifice de référencement 25.During assembly, the flexibility of the flexible part 32 allows it to move closer to the rigid part 31. This movement allows that in the event of misalignment of the pin and the referencing orifice 30, flexible part 32 bends in slot 33, allowing referencing pin 30 to pass into referencing orifice 25.

Par ailleurs, l'élasticité de cette partie souple 32 va générer une force de rappel, de sorte que la partie souple 32 va exercer une poussée sur le bord 26 de l'orifice de référencement 25 et déplacer le pion de référencement 30 vers la partie du bord qui est en vis-à-vis de la partie rigide 31. Cette partie rigide 31 assure ainsi la précision du référencement.Furthermore, the elasticity of this flexible part 32 will generate a restoring force, so that the flexible part 32 will exert a thrust 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 precision of the referencing.

Ici, on peut observer que le jeu subsistant 27 après le montage est très faible, plus de huit fois inférieur au jeu J de l'art antérieur.Here, it can be observed that the remaining clearance 27 after assembly is very small, more than eight times less than the clearance J of the prior art.

Ce jeu 27 peut même être nul, notamment avec la partie souple 32 en contrainte contre le bord de l'orifice et exerçant une poussée plaquant la partie rigide 31 contre le bord 26 de l'orifice 25.This clearance 27 may even be zero, in particular with the flexible part 32 constrained against the edge of the orifice and exerting a thrust pressing the rigid part 31 against the edge 26 of the orifice 25.

Notamment, comme ici, cette poussée s'exerce selon une direction transversale à la fente 33.In particular, as here, this thrust is exerted in a direction transverse to the slot 33.

De plus, le support 20 est enfoncé avec sa face portant les LED 21, 22 en appui contre la première zone d'appui 36. Ainsi comme illustré en figure 7b, cette première zone d'appui rigide 36 est plaquée sur une portion du support 20 adjacente au bord 26 de l'orifice de référencement 25 correspondant.In addition, the support 20 is pushed in with its face carrying the LEDs 21, 22 resting against the first support zone 36. Thus, as illustrated in figure 7b , this first rigid bearing zone 36 is pressed against a portion of the support 20 adjacent to the edge 26 of the corresponding referencing orifice 25 .

Dans cet exemple, la pièce optique 1 comprend trois pions de référencement 30 coopérant avec trois orifices de référencement 25, de manière à réaliser un isostatisme selon trois directions orthogonales entre elles.In this example, the optical part 1 comprises three referencing pins 30 cooperating with three referencing orifices 25, so as to achieve isostatism in three mutually orthogonal directions.

Comme on peut le voir en figures 4 et 5, qui sont ici des vues de dessus du module 100, le support 20 est en appui sur les trois premières zones d'appui 36, qui sont coplanaires entre elles, et sont donc comprises dans un plan A, ici horizontal, symbolisé par les rectangles en pointillés en figure 4. Cela permet un positionnement du support 20 selon ce plan A et donc un assemblage avec un référencement vertical. En effet, cela permet un positionnement précis par rapport à un déplacement selon la direction verticale Z. Autrement dit lors de l'assemblage, les premières zones d'appui 36 forment une butée selon la direction verticale Z.As can be seen in figure 4 And 5 , which here are top views of the module 100, the support 20 rests 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 rectangles dotted in figure 4 . This allows a positioning of the support 20 according to this plane A and therefore an assembly with a vertical referencing. Indeed, this allows precise positioning with respect to a movement in the vertical direction Z. In other words, during assembly, the first support zones 36 form an abutment in the vertical direction Z.

Ici, les fentes 33 des deux pions de référencement 30 avant, agencés en haut de ces figures, sont alignées selon une direction d'alignement B, ici parallèle à une direction transversale Y.Here, the slots 33 of the two front referencing pins 30, arranged at the top of these figures, are aligned in an alignment direction B, here parallel to a transverse direction Y.

Ici, les orifices de référencement 25 avant sont légèrement oblongs, de manière à ce que ces pions de référencement 30 avant présentent un jeu à chaque extrémité latérale de leurs fentes 33 et pas de jeu perpendiculairement et de part et d'autres de celle-ci. Ainsi un jeu transversal est permis selon cette direction d'alignement B.Here, the front referencing holes 25 are slightly oblong, so that these front referencing pins 30 have play at each lateral end of their slots 33 and no play perpendicularly and on either side thereof . Thus a transverse clearance is allowed along this alignment direction B.

Par ailleurs, le débattement des parties souples 32 correspondantes permet un assemblage avec moins de risque et permet le plaquage des deux parties rigides 31 contre le bord 26 des orifices de référencement 25, donc un plaquage selon une ligne de référencement 29 parallèle à la direction d'alignement B. On a donc un positionnement longitudinal, soit un référencement longitudinal, puisque la ligne de référencement 29 forme la limite de recul du support 20 par rapport à la pièce optique 1.Furthermore, the movement of the corresponding flexible parts 32 allows an assembly with less risk and allows the pressing of the two rigid parts 31 against the edge 26 of the referencing orifices 25, therefore a pressing along a referencing line 29 parallel to the direction of alignment B. There is therefore a longitudinal positioning, i.e. a longitudinal referencing, since the reference line 29 forms the limit of recoil of the support 20 with respect to the optical part 1.

Le troisième pion de référencement 30, ici à l'arrière, est à distance de la direction d'alignement B, donc de la ligne passant par les fentes 33 des pions de référencement 30 avant.The third reference 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 reference pins 30.

Cela permet un meilleur appui vertical du support 20.This allows a better vertical support of the support 20.

De plus, la fente 33 de ce pion de référencement 30 arrière est agencée de manière à être aligné avec un droite longitudinale C perpendiculaire à la direction d'alignement B.In addition, the slot 33 of this rear referencing pin 30 is arranged so as to be aligned with a longitudinal straight line C perpendicular to the alignment direction B.

Ainsi, le débattement de la partie souple 32 de ce pion de référencement 30 arrière permet le plaquage de la partie rigide 31 correspondante contre le bord de l'orifice de référencement 25, donc un plaquage selon un point de cette droite longitudinale C. Comme les pions de référencement 30 avant permettent un jeu uniquement transversal, soit parallèlement à la direction d'alignement B, ce point forme ainsi une limite de déplacement selon un déplacement transversal du support 20, et donc forme un référencement transversal entre la pièce optique 1 et le support 20.Thus, the displacement of the flexible part 32 of this rear referencing pin 30 allows the pressing of the corresponding rigid part 31 against the edge of the referencing orifice 25, therefore a pressing according to a point of this longitudinal straight line C. As the front referencing pins 30 allow only transverse play, i.e. parallel to the alignment direction B, this point thus forms a displacement limit according to a transverse displacement of the support 20, and therefore forms a transverse referencing between the optical part 1 and the bracket 20.

Ces trois pions de référencement 30 permettent donc à eux seuls un référencement du support 20 sur la pièce optique 1 selon les trois directions orthogonales : longitudinale X, transversale Y et verticale Z.These three referencing pins 30 therefore alone allow referencing of the support 20 on the optical part 1 according to the three orthogonal directions: longitudinal X, transverse Y and vertical Z.

A noter que l'orifice de référencement 25 arrière est ouvert sur le côté à l'arrière de manière à permettre un jeu longitudinal, de manière à faciliter le débattement des parties souples 32 des pions de référencement 30 avant.It should be noted that the rear referencing orifice 25 is open on the rear side so as to allow longitudinal play, so as to facilitate movement of the flexible parts 32 of the front referencing pins 30 .

Ici les pions de référencement 30 sont agencés autour des pluralités de collimateurs 2', 2", voire de manière adjacente à certains collimateurs 2', comme on peut le voir en figure 7b.Here the referencing pins 30 are arranged around the plurality of collimators 2', 2", or even adjacent to certain collimators 2', as can be seen in figure 7b .

A noter que selon une variante non représentée, un tel référencement isostatique peut être obtenu avec trois pions de référencement, dont au moins l'un diffère des pions de référencement 30 précédents en ce que la partie souple diffère en ce qu'elle est formée par une lame ressort, notamment en métal. Cette lame peut être plantée ou emmanchée dans le pion de référencement, la lame pouvant être déplacée vers la partie rigide en étant mise sous contrainte élastique.It should be noted that according to a variant not shown, such isostatic referencing can be obtained with three referencing pins, at least one of which differs from the previous referencing pins 30 in that the flexible part differs in that it is formed by a leaf spring, 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 placed under elastic stress.

Selon une variante non représentée, un tel référencement isostatique peut être obtenu avec trois pions de référencement, dont au moins l'un diffère des pions de référencement 30 précédents en ce que la partie rigide est constituée d'un premier matériau, notamment du PC, et la partie souple est constituée d'un deuxième matériau, notamment du silicone, permettant ainsi une déformation élastique avec augmentation de la contrainte lorsque la partie souple est comprimée vers la partie rigide.According to a variant not shown, such isostatic referencing can be obtained with three referencing pawns, at least one of which differs from the pawns of referencing 30 above in that the rigid part consists of a first material, in particular PC, and the flexible part consists of a second material, in particular silicone, thus allowing an elastic deformation with an increase in the stress when the part flexible is compressed towards the rigid part.
