Description

La présente invention concerne un module lumineux pour véhicule automobile. Elle trouve une application particulière mais non limitative dans les feux de signalisation additionnels.The present invention relates to a light module for a motor vehicle. It finds a particular but non-limiting application in additional signaling lights.

Un module lumineux tel qu'un feu de signalisation additionnel, connu de l'homme du métier, comprend au moins une source de lumière, un support de source de lumière, un boîtier ouvert, un élément de fermeture du boîtier, un faisceau de connexion électrique pour relier ladite au moins une source de lumière à un connecteur extérieur du véhicule automobile. Le module lumineux est fixé à l'aide d'une vis sur un boîtier du véhicule automobile fermé par une glace et disposé au niveau de grille de la face avant du véhicule automobile. Il est en particulier fixé dans un support de glace au niveau de ladite grille.A light module such as an additional traffic light, known to those skilled in the art, comprises at least one light source, a light source support, an open casing, a casing closing element, a connection harness electric to connect said at least one light source to an exterior connector of the motor vehicle. The light module is fixed by means of a screw to a casing of the motor vehicle closed by a glass and placed at the grid level of the front face of the motor vehicle. It is in particular fixed in a glass support at the level of said grid.

Un inconvénient de cet état de la technique antérieur est qu'en raison des contraintes d'environnement sur le véhicule automobile, il y a peu d'espace pour monter le module lumineux sur le véhicule automobile. Il est difficile de monter/démonter le module lumineux avec un tournevis en raison de la présence d'autres pièces telles que le radiateur qui se trouvent derrière le module lumineux. L'accès pour le montage/démontage via un tournevis est donc difficile. Le document JP 2017-134895 montre un dispositif lumineux comprenant un module lumineux monté sur un boîtier.A disadvantage of this state of the prior art is that due to the environmental constraints on the motor vehicle, there is little space to mount the light module on the motor vehicle. It is difficult to assemble/disassemble the light module with a screwdriver due to the presence of other parts such as the heat sink behind the light module. Access for assembly/disassembly via a screwdriver is therefore difficult. The document JP 2017-134895 shows a light device comprising a light module mounted on a housing.

Dans ce contexte, la présente invention vise à proposer un dispositif lumineux qui permet de résoudre l'inconvénient mentionné.In this context, the present invention aims to propose a luminous device which makes it possible to solve the drawback mentioned.

A cet effet, l'invention propose un dispositif lumineux dont les caractéristiques sont présentées dans la revendication 1.To this end, the invention proposes a luminous device whose characteristics are presented in claim 1.

Ainsi, comme on va le voir en détail ci-après, grâce au logement de positionnement, aux rainures, et à la patte d'accroche, il n'est plus nécessaire d'utiliser un tournevis pour fixer le module lumineux. Par ailleurs, le mouvement de rotation permet de monter facilement le module lumineux sur le boîtier du véhicule automobile et facilite l'accès au module lumineux à un opérateur. Par ailleurs, le fait de ne plus utiliser de tournevis évite d'abîmer le support de glace puisqu'il n'y a plus d'action de vissage/dévissage sur le support de glace.Thus, as will be seen in detail below, thanks to the positioning housing, the grooves, and the attachment lug, it is no longer necessary to use a screwdriver to fix the light module. Furthermore, the rotational movement makes it possible to easily mount the light module on the casing of the motor vehicle and facilitates access to the light module for an operator. Furthermore, the no longer using a screwdriver avoids damaging the crystal support since there is no longer any screwing/unscrewing action on the crystal support.

Des caractéristiques optionnelles du dispositif lumineux sont présentées dans les revendications dépendantes.Optional features of the light device are set out in the dependent claims.

Le dispositif lumineux 1 pour véhicule automobile selon l'invention est décrit en référence aux figures 1a à 12d. Par véhicule automobile, on entend tout type de véhicule motorisé.The luminous device 1 for a motor vehicle according to the invention is described with reference to the figures 1a to 12d . Motor vehicle means any type of motorized vehicle.

Le module lumineux 1 est juxtaposé à un boîtier 3 du véhicule automobile, le tout formant un dispositif lumineux 4. Le module lumineux 1 fait ainsi partie d'un dispositif lumineux 4 illustré sur la figure 1a. Dans des modes de réalisation non limitatifs, le dispositif lumineux 4 est un feu de signalisation et/ou un projecteur, ou un dispositif d'éclairage intérieur.The light module 1 is juxtaposed with a casing 3 of the motor vehicle, the whole forming a light device 4. The light module 1 thus forms part of a light device 4 illustrated in the picture 1a . In non-limiting embodiments, the light device 4 is a traffic light and/or a projector, or an interior lighting device.

Dans un mode de réalisation non limitatif illustré sur la figure 1a, le boîtier 3 présente une ouverture fermée par une glace 31. Dans des modes de réalisation non limitatifs, le boîtier 3 comprend au moins un élément optique 30 tel qu'illustré sur la figure 3a refermé par une glace 31 tel qu'illustré sur la figure 1a In a non-limiting embodiment illustrated in the picture 1a , the housing 3 has an opening closed by a glass 31. In non-limiting embodiments, the housing 3 comprises at least one optical element 30 as illustrated in the picture 3a closed by a glass 31 as shown in the picture 1a

On notera que le boîtier 3 peut comprendre d'autres composants configurés pour émettre un faisceau lumineux indépendamment du module lumineux 1. Le boîtier 3 est autrement appelé deuxième boîtier 3 dans la suite de la description.It will be noted that the box 3 can comprise other components configured to emit a light beam independently of the light module 1. The box 3 is otherwise called the second box 3 in the remainder of the description.

Le mode de réalisation de la figure 1a est pris comme exemple non limitatif dans la suite de la description. La glace 31 est formée d'un support de glace 33 et d'une pièce optique transparente 34. Elle permet de fermer le boîtier 3. Le boîtier 3 comprend en outre un support d'élément optique 32. Tel qu'illustré sur la figure 8, le support d'élément optique 32 comprend un orifice 320 à travers lequel un bout 30c de l'élément optique 30 peut passer. Dans un mode de réalisation non limitatif, l'orifice 320 a une forme hexagonale qui coopère avec une forme hexagonale du bout 30c de l'élément optique 30. L'élément optique 30 est ainsi maintenu en position tel qu'illustré sur la figure 9a. Par ailleurs, le support d'élément optique 32 comprend un corps 321 longitudinal dans lequel le corps 30b de l'élément optique 30 peut se loger tel qu'illustré sur la figure 9b. Le support d'élément optique 32 est configuré pour coopérer avec le support de glace 33 tel qu'illustré sur la figure 10. Comme on peut le voir, le support de glace 33 recouvre le support d'élément optique 32.The embodiment of the picture 1a is taken as a non-limiting example in the remainder of the description. The lens 31 is formed by a lens support 33 and a transparent optical part 34. It allows the housing 3 to be closed. The housing 3 also comprises an optical element support 32. As illustrated in the figure 8 , the optical element holder 32 includes an orifice 320 through which a tip 30c of the optical element 30 can pass. In a non-limiting embodiment, the orifice 320 has a hexagonal shape which cooperates with a hexagonal shape of the end 30c of the optical element 30. The optical element 30 is thus held in position as illustrated in the figure 9a . Furthermore, the optical element support 32 comprises a longitudinal body 321 in which the body 30b of the optical element 30 can be housed as illustrated in the figure 9b . The optical element support 32 is configured to cooperate with the crystal support 33 as illustrated in the figure 10 . As can be seen, the lens support 33 covers the optical element support 32.

Le boîtier 3 comprend en outre un support d'accroche 310 pour fixer le module lumineux 1 sur ledit boîtier 3 et le bloquer en position. Dans un premier mode de réalisation non limitatif illustré sur la figure 1b, le support d'accroche 310 est solidaire dudit support de glace 33. Comme on peut le voir sur la figure 1b, la patte d'accroche 124 du module lumineux 1 coopère avec le support d'accroche 310 du support de glace 33.The box 3 further comprises a hooking support 310 to fix the light module 1 on said box 3 and lock it in position. In a first non-limiting embodiment illustrated in the figure 1b , the attachment support 310 is integral with said ice support 33. As can be seen in the figure 1b , the attachment tab 124 of the light module 1 cooperates with the attachment support 310 of the lens support 33.

Dans un deuxième mode de réalisation illustré sur la figure 11a, le support d'accroche 310 est solidaire dudit support d'élément optique 32. Comme on peut le voir sur la figure 11b, la patte d'accroche 124 du module lumineux 1 coopère avec le support d'accroche 310 du support d'élément optique 32.In a second embodiment illustrated in the picture 11a , the attachment support 310 is integral with said optical element support 32. As can be seen in the figure 11b , the attachment lug 124 of the light module 1 cooperates with the attachment support 310 of the optical element support 32.

Dans un mode de réalisation non limitatif, le module lumineux 1 est un feu de signalisation additionnel juxtaposé au boîtier 3 comprenant ledit au moins un élément optique 30 refermé par une glace 31. Le feu de signalisation permet de réaliser une fonction lumineuse de signalisation. Le feu de signalisation est pris comme exemple non limitatif dans la suite de la description. Bien entendu, l'invention ne se limite pas au feu de signalisation, mais peut s'appliquer à d'autres types de modules lumineux. L'élément optique 30 est configuré pour coopérer avec au moins une source de lumière 10 (décrite plus loin) dudit module lumineux 1. Dans un mode de réalisation non limitatif, il forme un projecteur. Le projecteur permet de réaliser une fonction lumineuse d'éclairage. Bien entendu, l'invention ne se limite pas au projecteur. Ainsi, dans le mode de réalisation non limitatif pris comme exemple, le dispositif lumineux 4 est un projecteur et un feu de signalisation.In a non-limiting embodiment, the light module 1 is an additional traffic light juxtaposed to the housing 3 comprising said at least one optical element 30 closed by a window 31. The signaling light makes it possible to carry out a luminous signaling function. The traffic light is taken as a non-limiting example in the remainder of the description. Of course, the invention is not limited to the traffic light, but can be applied to other types of light modules. The optical element 30 is configured to cooperate with at least one light source 10 (described later) of said light module 1. In one non-limiting embodiment, it forms a projector. The projector makes it possible to perform a luminous lighting function. Of course, the invention is not limited to the projector. Thus, in the non-limiting embodiment taken as an example, the light device 4 is a projector and a traffic light.

Dans un mode de réalisation non limitatif, la fonction lumineuse de signalisation est :

  • un clignotant Tl appelé en anglais « Turn Indicator », et/ou,

Tel qu'illustré sur les figures 1a à 2, le module lumineux 1 est monté sur le boîtier 3 du véhicule automobile. En particulier, il est monté à l'arrière 3a dudit boîtier 3. Dans un mode de réalisation non limitatif, le module lumineux 1 est monté entre le boîtier 3 et la carrosserie (non illustrée) du véhicule automobile. Il est monté dans un espace limité, notamment dans le sens de la profondeur. Dans un exemple non limitatif cet espace est d'environ 10 centimètres. Dans un exemple non limitatif, il existe un jeu d'environ 10mm entre le module lumineux 1 et la carrosserie. Tel qu'illustré sur la figure 1a, le module lumineux 1 est juxtaposé au boîtier 3. La glace 31 du boîtier 3 est du côté opposé au module lumineux 1. Elle se trouve côté avant 3b du boîtier 3.As shown on the figures 1a to 2 , the light module 1 is mounted on the housing 3 of the motor vehicle. In particular, it is mounted at the rear 3a of said housing 3. In one non-limiting embodiment, the light module 1 is mounted between the housing 3 and the bodywork (not shown) of the motor vehicle. It is mounted in a limited space, especially in the direction of depth. In a non-limiting example, this space is approximately 10 centimeters. In a non-limiting example, there is a clearance of approximately 10mm between the light module 1 and the bodywork. As shown on the picture 1a , light module 1 is juxtaposed with case 3. Glass 31 of case 3 is on the opposite side to light module 1. It is located on the front side 3b of case 3.

L'élément optique 30 du boîtier 3 s'étend du côté de ladite glace 31. Dans l'exemple non limitatif illustré sur les figures 3a et 3b, l'élément optique 30 du boîtier 3 est un guide de lumière qui s'étend le long du boîtier 3. Ce mode de réalisation non limitatif est pris comme exemple non limitatif dans la suite de la description. Tel qu'illustré sur les figures 7a et 7b, le guide de lumière 30 comprend des éléments réfléchissants 30d, un corps 30b avec deux extrémités 30c, une des extrémités 30c comprenant une surface plane 30a. La surface plane 30a est configurée pour être disposée en regard de la source de lumière 10. Le corps 30b est configuré pour être disposé dans le support d'élément optique 32 tel qu'illustré sur la figure 9b. Une des extrémités 30c du corps 30b est configurée pour s'insérer dans l'interface 122 du boîtier ouvert 12 décrite plus loin. Dans un mode de réalisation non limitatif, ladite extrémité 30c a une forme hexagonale de sorte à s'insérer correctement dans l'orifice 321 du support d'élément optique 32. Par ailleurs, dans un mode de réalisation non limitatif illustré sur la figure 7b, le guide de lumière 30 comprend en outre des ergots de positionnement 300 du module lumineux 1. Dans un exemple non limitatif illustré, il comprend deux ergots de positionnement 300. Dans un mode de réalisation non limitatif, le guide de lumière 30 est positionné au centre desdits ergots de positionnement 300. Les ergots de positionnement 300 sont disposés autour du guide de lumière 30. Cela permet un meilleur positionnement par rapport à ladite source de lumière 10 décrite ci-après. Les ergots de positionnement 300 sont disposés sur la périphérie d'une des extrémités 30c du guide de lumière 30. Les ergots de positionnement 300 sont configurés pour coopérer avec des rainures 127 et des zones de guidage 128 d'un logement de positionnement 126 du boîtier ouvert 12 tel que décrit plus loin.The optical element 30 of the housing 3 extends from the side of said glass 31. In the non-limiting example illustrated in the figures 3a and 3b , the optical element 30 of the housing 3 is a light guide which extends along the housing 3. This non-limiting embodiment is taken as a non-limiting example in the remainder of the description. As shown on the figures 7a and 7b , the light guide 30 comprises reflective elements 30d, a body 30b with two ends 30c, one of the ends 30c comprising a flat surface 30a. The flat surface 30a is configured to be placed opposite the light source 10. The body 30b is configured to be placed in the element support optical 32 as shown in the figure 9b . One of the ends 30c of the body 30b is configured to fit into the interface 122 of the open box 12 described below. In a non-limiting embodiment, said end 30c has a hexagonal shape so as to fit correctly into the orifice 321 of the optical element support 32. Furthermore, in a non-limiting embodiment illustrated in the figure 7b , the light guide 30 further comprises positioning lugs 300 of the light module 1. In a non-limiting example illustrated, it comprises two positioning lugs 300. In a non-limiting embodiment, the light guide 30 is positioned at the center of said positioning lugs 300. The positioning lugs 300 are arranged around the light guide 30. This allows better positioning with respect to said light source 10 described below. The positioning lugs 300 are arranged on the periphery of one of the ends 30c of the light guide 30. The positioning lugs 300 are configured to cooperate with grooves 127 and guide zones 128 of a positioning housing 126 of the housing open 12 as described below.

Tel qu'illustré sur les figures 4a à 5, le module lumineux 1 comprend :

  • au moins une source de lumière 10,
  • un support de source de lumière 11,
  • un boîtier ouvert 12,
  • un élément de fermeture 13 du boîtier ouvert 12,
  • un élément primaire de connexion électrique 14 relié au support de source de lumière 11,
  • un élément secondaire de connexion électrique 15 relié au boîtier.
As shown on the figures 4a to 5 , light module 1 comprises:

  • a light source support 11,
  • an open case 12,
  • a closing element 13 of the open casing 12,
  • a primary electrical connection element 14 connected to the light source support 11,
  • a secondary electrical connection element 15 connected to the housing.

Ces différents éléments sont décrits en détail ci-après.These various elements are described in detail below.

La source de lumière 10 est illustrée sur les figures 3b, 4b et 5. Dans un mode de réalisation non limitatif illustré, le module lumineux 1 comprend une unique source de lumière 10. Dans un autre mode de réalisation non limitatif non illustré, le module lumineux 1 comprend une pluralité de sources de lumière 10. Dans un mode de réalisation non limitatif, ladite au moins une source de lumière 10 est une source de lumière à semi-conducteur. Dans un mode de réalisation non limitatif, la source de lumière à semi-conducteur fait partie d'une diode électroluminescente. Par diode électroluminescente, on entend tout type de diodes électroluminescentes, que ce soit dans des exemples non limitatifs des LED (« Light Emitting Diode »), des OLED (« organic LED »), des AMOLED (Active-Matrix-Organic LED), ou encore des FOLED (Flexible OLED).The light source 10 is illustrated in the figure 3b , 4b And 5 . In one illustrated non-limiting embodiment, the light module 1 comprises a single light source 10. In another non-illustrated non-limiting embodiment, the light module 1 comprises a plurality of light sources 10. In one embodiment non-limiting, said at least one light source 10 is a semiconductor light source. In one non-limiting embodiment, the semiconductor light source is part of a light emitting diode. By light-emitting diode, we mean any type of light-emitting diode, whether in non-limiting examples LED (“Light Emitting Diode”), OLED (“organic LED”), AMOLED (Active-Matrix-Organic LED), or FOLED (Flexible OLED).

Ladite au moins une source de lumière 10 est configurée pour émettre des rayons lumineux qui coopèrent avec l'élément optique 30 pour générer un faisceau lumineux. Ledit faisceau lumineux permet de réaliser la fonction lumineuse de signalisation. Dans l'exemple non limitatif illustré sur la figure 3b, ladite au moins une source de lumière 10 coopère avec le guide de lumière 30. Elle est disposée en regard d'une extrémité du guide de lumière 30. Dans un mode de réalisation non limitatif, ladite au moins une source de lumière 10 est disposée sur le support de source de lumière 11 décrit ci-après.Said at least one light source 10 is configured to emit light rays which cooperate with the optical element 30 to generate a light beam. Said light beam makes it possible to perform the luminous signaling function. In the non-limiting example illustrated in the figure 3b , said at least one light source 10 cooperates with the light guide 30. It is arranged facing one end of the light guide 30. In a non-limiting embodiment, said at least one light source 10 is arranged on the light source support 11 described below.

Le support de source de lumière 11 est illustré sur les figures 3b, 4b et 5. Il est pris en sandwich entre le boîtier ouvert 12 et l'élément de fermeture 13. Il s'étend à 90° par rapport à l'axe d'émission des rayons lumineux de ladite au moins une source de lumière 10. Dans un mode de réalisation non limitatif illustré sur la figure 5, le support de source de lumière 11 est une carte à circuit imprimé, autrement appelée carte PCBA et connue sous l'acronyme anglo-saxon « Printed Circuit Board Assembly ». Cette carte PCBA comprend des composants électroniques (non illustrés) tels que dans un exemple non limitatif un dispositif de contrôle (non illustré) de ladite au moins une source de lumière 10, autrement appelé « driver » en anglais.The light source holder 11 is illustrated in the figure 3b , 4b And 5 . It is sandwiched between the open casing 12 and the closure element 13. It extends at 90° relative to the axis of emission of the light rays from said at least one light source 10. In one mode non-limiting embodiment illustrated on the figure 5 , the light source support 11 is a printed circuit board, otherwise called a PCBA board and known by the acronym “Printed Circuit Board Assembly”. This PCBA board comprises electronic components (not shown) such as, in a non-limiting example, a control device (not shown) of said at least one light source 10, otherwise called a “driver”.

Tel qu'illustré sur la figure 5, l'élément primaire de connexion électrique 14 est relié au support de source de lumière 11. Tel qu'illustré sur la figure 4b, il coopère avec l'élément secondaire de connexion électrique 15 pour réaliser une connexion électrique. Dans un mode de réalisation non limitatif, ledit élément primaire de connexion électrique 14 est soudé sur le support de source de lumière 11. Dans un mode de réalisation non limitatif illustré, ledit élément primaire de connexion électrique 14 est un connecteur femelle. Le fait d'avoir un connecteur femelle sur le support de source de lumière 11 permet d'avoir un appui surfacique plus stable que si c'était un connecteur mâle. Tel qu'illustré sur la figure 5, le connecteur femelle 14 est composé de deux broches 14a, 14b (l'une positive, l'autre négative) assemblées sur le support de source de lumière 11. Dans un exemple non limitatif, les deux broches 14a, 14b sont soudées sur le support de source de lumière 11.As shown on the figure 5 , the primary electrical connection element 14 is connected to the light source support 11. As illustrated in the figure 4b , it cooperates with the secondary electrical connection element 15 to make an electrical connection. In a non-limiting embodiment, said primary electrical connection element 14 is welded to the light source support 11. In an illustrated non-limiting embodiment, said primary electrical connection element 14 is a female connector. The fact of having a female connector on the light source support 11 makes it possible to have a more stable surface support than if it were a male connector. As shown on the figure 5 , the female connector 14 is composed of two pins 14a, 14b (one positive, the other negative) assembled on the light source support 11. In a non-limiting example, the two pins 14a, 14b are soldered on the light source holder 11.

Dans un mode de réalisation non limitatif non illustré sur la figure 5, le support de source de lumière 11 comprend en outre au moins un orifice de référence 110 configuré pour le positionner par rapport au boîtier ouvert 12. Dans une variante de réalisation non limitative, il comprend deux orifices de référence 110. Ces derniers coopèrent avec deux pions de référence 120 du boîtier ouvert 12. Ils permettent un référencement selon des axes Y et Z parallèles au support de source de lumière 11.In a non-limiting embodiment not illustrated in the figure 5 , the light source support 11 further comprises at least one reference orifice 110 configured to position it relative to the open housing 12.

In a non-limiting embodiment, the closing element 13 is a radiator or a closing cover. In the nonlimiting example illustrated, it is a radiator. In one non-limiting embodiment, closure member 13 is secured to open housing 12 by welding. Light source holder 11 is secured to closure member 13. When closure member 13 is a radiator, in one non-limiting embodiment, the light source holder 11 is attached to the radiator 13 via an adhesive. When the closure element 13 is a closure cap, in a non-limiting embodiment not illustrated, the light source support 11 is fixed to the closure cap 13 via fixing clips or rivets. In a non-limiting embodiment illustrated in the figure 5 , the closure element 13 comprises at least one slide 131 for positioning the open casing 12. In a non-limiting variant embodiment, it comprises three slides 131. They cooperate with the positioning lugs 121 of the open casing 12.

Dans un mode de réalisation non limitatif illustré sur la figure 6a, le boîtier ouvert 12 comprend au moins un pion de référence 120 pour le positionnement du support de source de lumière 11. Dans une variante de réalisation non limitative, il comprend deux pions de référence 120. Les deux pions de référence 120 sont configurés pour assurer le positionnement du support de source de lumière 11. Ils coopèrent avec les orifices de référence 110 du support de source de lumière 11. Dans un mode de réalisation non limitatif illustré sur la figure 6a, le boîtier ouvert 12 comprend au moins une patte de positionnement 121. Dans une variante de réalisation non limitative, il comprend trois pattes de positionnement 121. Les trois pattes de positionnement 121 sont configurées pour positionner correctement le boîtier ouvert 12 par rapport à l'élément de fermeture du boîtier 13. Ces pattes de positionnement 121 sont configurées pour traverser les orifices de positionnement 111 du support de source de lumière et s'engager dans les glissières 131 de l'élément de fermeture 13.The open housing 12 is illustrated in the figures 1b to 6b . It is configured to cover the light source support 11. In a non-limiting embodiment illustrated in the figure 6a , the open box 12 comprises at least one reference pin 120 for positioning the light source support 11. In a non-limiting variant embodiment, it comprises two reference pins 120. The two reference pins 120 are configured to ensure the positioning of the light source support 11. They cooperate with the reference orifices 110 of the light source support 11. In a non-limiting embodiment illustrated in the figure 6a , the open housing 12 comprises at least one positioning lug 121. In a non-limiting variant embodiment, it comprises three positioning lugs 121. The three positioning lugs 121 are configured to correctly position the open housing 12 with respect to the closure element of the housing 13. These positioning lugs 121 are configured to pass through the positioning holes 111 of the light source support and engage in the slides 131 of the closure element 13.

Dans un mode de réalisation non limitatif illustré sur les figures 3b à 6b, le boîtier ouvert 12 comprend en outre une interface 122 avec l'élément optique 30. Dans une variante de réalisation non limitative, cette interface 122 est circulaire. Dans l'exemple non limitatif du guide de lumière 30, tel qu'illustré sur la figure 3b, une extrémité 30c du guide de lumière 30 peut être insérée dans cette interface 122. L'interface 122 se trouve en regard de la source de lumière 10 de sorte que l'extrémité 30c, en particulier sa surface plane 30a, du guide de lumière 30 se trouve en regard de la source de lumière 10. Ainsi, les rayons lumineux de la source de lumière 10 sont dirigés dans le guide de lumière 30. L'interface 122 comprend un joint torique 1220 qui assure l'étanchéité.In a non-limiting embodiment illustrated in the figures 3b to 6b , the open housing 12 further comprises an interface 122 with the optical element 30. In a non-limiting variant embodiment, this interface 122 is circular. In the non-limiting example of the light guide 30, as illustrated in the figure 3b , one end 30c of the light guide 30 can be inserted into this interface 122. The interface 122 is facing the light source 10 so that the end 30c, in particular its flat surface 30a, of the light guide 30 is next to the source of light 10. Thus, the light rays from the light source 10 are directed into the light guide 30. The interface 122 includes an O-ring 1220 which provides the seal.

Dans un mode de réalisation non limitatif illustré sur les figures, le boîtier ouvert 12 comprend en outre une partie connecteur 123. Tel qu'illustré sur la figure 6b, une partie de connexion secondaire 151 de l'élément secondaire de connexion électrique 15 est insérée dans la partie connecteur 123, et configuré pour coopérer avec un connecteur extérieur (non illustré) du véhicule automobile qui permet d'alimenter la carte PCBA.In a non-limiting embodiment illustrated in the figures, the open housing 12 further comprises a connector part 123. As illustrated in the figure 6b , a secondary connection part 151 of the secondary electrical connection element 15 is inserted into the connector part 123, and configured to cooperate with an external connector (not shown) of the motor vehicle which makes it possible to supply the PCBA board.

Dans un mode de réalisation non limitatif illustré sur la figure 6a, le boîtier ouvert 12 comprend en outre un logement de positionnement 126 avec une pluralité de rainures de 127. Tel qu'illustré sur la figure 6c, le logement de positionnement 126 comprend un axe central Ax1 perpendiculaire à la direction longitudinale du boîtier ouvert 12. Le logement de positionnement 126 comprend une section transversale sensiblement circulaire et débouche sur l'interface 122 et l'intérieur du boîtier ouvert 12. Les rainures 127 sont aménagées dans le logement 126. Tel qu'illustré sur la figure 6b, le logement de positionnement 126 comprend une collerette 1260 dans laquelle lesdites rainures 127 sont réalisées. Lesdites rainures 127 partent de ladite collerette 1260 pour déboucher dans ledit logement 126, côté intérieur du boîtier ouvert 12. Le logement de positionnement 126 permet d'accueillir le guide de lumière 30, en particulier une de ses extrémités 30c qui peut s'insérer dans ledit logement de positionnement 126. Les rainures 127 permettent de bloquer les ergots de positionnement 300 du guide de lumière 30.In a non-limiting embodiment illustrated in the figure 6a , the open housing 12 further includes a positioning recess 126 with a plurality of grooves 127. As shown in the figure 6c , the positioning housing 126 comprises a central axis Ax1 perpendicular to the longitudinal direction of the open housing 12. The positioning housing 126 comprises a substantially circular cross section and opens onto the interface 122 and the interior of the open housing 12. The grooves 127 are located in apartment 126. As shown in the figure 6b , the positioning housing 126 comprises a flange 1260 in which said grooves 127 are formed. Said grooves 127 depart from said collar 1260 to open into said housing 126, on the inside of the open box 12. The positioning housing 126 makes it possible to accommodate the light guide 30, in particular one of its ends 30c which can be inserted into said positioning housing 126. The grooves 127 make it possible to block the positioning lugs 300 of the light guide 30.

Dans un exemple non limitatif non illustré, le logement de positionnement 126 comprend trois rainures 127. Dans un mode de réalisation non limitatif, les trois rainures 127 sont décalées angulairement de 120°. Dans un autre exemple non limitatif non illustré, il comprend deux rainures 127. Dans un mode de réalisation non limitatif, les deux rainures 127 sont décalées angulairement de 180°, à savoir elles sont disposées en regard l'une de l'autre. Le fait de décaler angulairement les rainures 127 permet d'avoir des zones de guidage 128 dans le logement de positionnement 126 tel qu'illustré sur la figure 6c. Tel qu'illustré sur la figure 6c, les zones de guidage 128 sont formées d'arcs de cercle. Ils sont situés sur la circonférence intérieure de la collerette 1260. Dans le mode de réalisation non limitatif illustré, il y a trois zones de guidages 128 dont deux se terminent par une butée 128b. Dans un mode de réalisation non limitatif illustré, un arc de cercle 128 est ainsi décalé de 120° par rapport à un arc de cercle adjacent.In a non-limiting example not illustrated, the positioning housing 126 comprises three grooves 127. In a non-limiting embodiment, the three grooves 127 are angularly offset by 120°. In another non-limiting example not illustrated, it comprises two grooves 127. In a non-limiting embodiment, the two grooves 127 are angularly offset by 180°, ie they are arranged opposite one another. The fact of angularly offsetting the grooves 127 makes it possible to have guide zones 128 in the positioning housing 126 as illustrated in the figure 6c . As shown on the figure 6c , the guide zones 128 are formed of circular arcs. They are located on the inner circumference of the collar 1260. In the non-limiting embodiment illustrated, there are three guide zones 128, two of which end in a stop 128b. In one illustrated non-limiting embodiment, an arc of a circle 128 is thus offset by 120° relative to an adjacent arc of a circle.

Dans un mode de réalisation non limitatif illustré sur les figures 1b et 4a, le boîtier ouvert 12 comprend en outre une patte d'accroche 124 au boîtier 3. La patte d'accroche 124 est configurée pour s'accrocher au support d'accroche 310 du boîtier 3. Comme on va le voir par la suite, le module lumineux 1 est configuré pour effectuer un mouvement de rotation et s'accrocher en fin de rotation à un deuxième boîtier 3 du véhicule automobile via sa patte d'accroche 124 de son boîtier ouvert 12. Selon un premier mode de réalisation non limitatif illustré sur la figure 1b, la patte d'accroche 124 coopère avec un support d'accroche 310 du support de glace 33 du boîtier 3. Notamment, elle est clipsée sur ledit support d'accroche 310. Selon un deuxième mode de réalisation non limitatif illustré sur la figure 11b, la patte d'accroche 124 coopère avec un support d'accroche 310 du support d'élément optique 32 du boîtier 3. Notamment, elle est clipsée sur ledit support d'accroche 310.In a non-limiting embodiment illustrated in the figure 1b And 4a , the open housing 12 further comprises a hooking tab 124 to the housing 3. The hooking tab 124 is configured to hook to the hooking support 310 of the housing 3. As will be seen later, the module light 1 is configured to perform a rotational movement and cling at the end of rotation to a second housing 3 of the motor vehicle via its hooking lug 124 of its open housing 12. According to a first non-limiting embodiment illustrated in the figure 1b , the hooking lug 124 cooperates with a hooking support 310 of the crystal support 33 of the housing 3. In particular, it is clipped onto said hooking support 310. According to a second non-limiting embodiment illustrated in the figure 11b , the attachment lug 124 cooperates with an attachment support 310 of the optical element support 32 of the housing 3. In particular, it is clipped onto said attachment support 310.

Dans un mode de réalisation non limitatif illustré sur la figure 3b, le boîtier ouvert 12 comprend en outre des moyens de centrage 125 de la source de lumière 10 avec l'élément optique 30.In a non-limiting embodiment illustrated in the figure 3b , the open housing 12 further comprises means 125 for centering the light source 10 with the optical element 30.

L'élément secondaire de connexion électrique 15 est illustré sur les figures 6a et 6b. Tel qu'illustré, l'élément secondaire de connexion électrique 15 est relié au boîtier ouvert 12. Dans un mode de réalisation non limitatif, ledit boîtier ouvert 12 est surmoulé sur l'élément secondaire de connexion électrique 15. Selon le processus de surmoulage, l'élément secondaire de connexion électrique 15 est mis en place dans un moule d'injection, puis la matière du boîtier ouvert 12 est injectée dans le moule d'injection pour obtenir la pièce. Cela permet d'assurer l'étanchéité et de respecter une côte précise d'assemblage. L'élément secondaire de connexion électrique 15 est configuré pour coopérer avec l'élément primaire de connexion électrique 14. Dans un mode de réalisation non limitatif, l'élément secondaire de connexion électrique 15 est un connecteur mâle. Le fait d'avoir un connecteur mâle sur le boîtier ouvert 12 est plus simple à fabriquer que d'avoir un connecteur mâle sur le support de source de lumière 11.The secondary electrical connection element 15 is illustrated in the figures 6a and 6b . As illustrated, the secondary electrical connection element 15 is connected to the open casing 12. In one non-limiting embodiment, said open casing 12 is overmolded on the secondary electrical connection element 15. According to the overmolding process, the secondary electrical connection element 15 is placed in an injection mold, then the material of the open box 12 is injected into the injection mold to obtain the part. This makes it possible to ensure tightness and to respect a precise assembly dimension. The secondary electrical connection element 15 is configured to cooperate with the primary electrical connection element 14. In one non-limiting embodiment, the secondary electrical connection element 15 is a male connector. Having a male connector on the open housing 12 is easier to manufacture than having a male connector on the light source holder 11.

L'assemblage selon un axe X perpendiculaire au support de source de lumière 11, entre le support de source de lumière 11 et le boîtier ouvert 12 est ainsi facile grâce au connecteur mâle 15 et au connecteur femelle 14 vu précédemment. La connexion électrique entre le connecteur mâle 15 et le connecteur femelle 14 lors de l'assemblage entre le support de source de lumière 11 et le boîtier ouvert 12 est ainsi simple à réaliser.The assembly along an axis X perpendicular to the light source support 11, between the light source support 11 and the open box 12 is thus easy thanks to the male connector 15 and the female connector 14 seen above. The electrical connection between the male connector 15 and the female connector 14 during assembly between the light source support 11 and the open box 12 is thus simple to make.

Tel qu'illustré sur les figures 6a et 6b, l'élément secondaire de connexion électrique 15 comprend :

  • une partie de connexion primaire 150 avec ledit élément primaire de connexion électrique 14, et
  • une partie de connexion secondaire 151 avec le connecteur extérieur du véhicule automobile.
As shown on the figures 6a and 6b , the secondary electrical connection element 15 comprises:
  • a primary connection part 150 with said primary electrical connection element 14, and
  • a secondary connection part 151 with the exterior connector of the motor vehicle.

Le fait que l'élément secondaire de connexion 15 permette à la fois une connexion avec la carte PCBA via la partie de connexion primaire 150, et une connexion avec le connecteur extérieur via la partie de connexion secondaire 151 permet de ne pas utiliser de faisceau de connexion électrique interne entre le support de source de lumière 11 et le connecteur extérieur du véhicule automobile qui entraînerait des problèmes de compatibilité électromagnétique. On évite ainsi des problèmes de compatibilité électromagnétique. Cela évite également d'avoir des problèmes de positionnement du faisceau de connexion électrique interne à l'intérieur du boîtier ouvert 12, une fois le boîtier ouvert 12, le support de source de lumière 11 et l'élément de fermeture 13 assemblés ensemble. En effet, dans le cas d'une utilisation d'un tel faisceau de connexion électrique interne, il serait nécessaire d'avoir une grande longueur pour pouvoir assurer le remplacement de la source de lumière 10.The fact that the secondary connection element 15 allows both a connection with the PCBA board via the primary connection part 150, and a connection with the external connector via the secondary connection part 151 makes it possible not to use a wiring harness. internal electrical connection between the light source holder 11 and the exterior connector of the motor vehicle which would cause electromagnetic compatibility problems. This avoids problems of electromagnetic compatibility. This also avoids having problems positioning the internal electrical connection harness inside the open box 12, once the open box 12, the light source support 11 and the closing element 13 are assembled together. Indeed, in the case of using such an internal electrical connection harness, it would be necessary to have a great length to be able to ensure the replacement of the light source 10.

La partie de connexion primaire 150 forme le connecteur mâle. Elle comprend deux broches 150a, 150b (l'une positive, l'autre négative) configurées pour coopérer respectivement avec les deux broches 14a, 14b de l'élément primaire de connexion électrique 14. Dans un mode de réalisation non limitatif, les deux broches 150a, 150b sont intégrées au boîtier ouvert 12 par surmoulage. Tel qu'illustré sur la figure 6b, la partie de connexion primaire 150 s'étend selon une première direction AX. Elle est en contact plan avec le boîtier ouvert 12 ce qui évite toute déformation et aux broches 150a, 150b de bouger.The primary connection part 150 forms the male connector. It comprises two pins 150a, 150b (one positive, the other negative) configured to cooperate respectively with the two pins 14a, 14b of the primary electrical connection element 14. In a non-limiting embodiment, the two pins 150a, 150b are integrated into the open casing 12 by overmoulding. As shown on the figure 6b , the primary connection part 150 extends along a first direction AX. It is in flat contact with the open housing 12 which prevents any deformation and the pins 150a, 150b from moving.

La partie de connexion secondaire 151 forme un connecteur mâle qui est configuré pour s'enficher dans un connecteur femelle formé (non illustré) dans le connecteur extérieur du véhicule automobile. Elle comprend deux broches 151a, 151b (l'une positive, l'autre négative). La partie de connexion secondaire 151 s'étend selon une seconde direction AY. La seconde direction AY fait un angle β avec la première direction AX compris entre 45° et 135°. Grâce à cet agencement avec un angle β, il est possible de monter le module lumineux 1 entre le deuxième boîtier 3 et la carrosserie du véhicule automobile selon l'axe X, et de le démonter pour le remplacer lorsque le dispositif lumineux 4 est monté sur le véhicule automobile. Cela permet également d'avoir de petites dimensions notamment en largeur du module lumineux 1 de sorte à pouvoir l'intégrer facilement dans l'espace entre le deuxième boîtier 3 et la carrosserie du véhicule automobile.The secondary connection part 151 forms a male connector which is configured to plug into a formed female connector (not shown) in the exterior connector of the motor vehicle. It comprises two pins 151a, 151b (one positive, the other negative). The secondary connection part 151 extends along a second direction AY. The second direction AY makes an angle β with the first direction AX comprised between 45° and 135°. Thanks to this arrangement with an angle β, it is possible to mount the light module 1 between the second housing 3 and the body of the motor vehicle along the X axis, and to dismantle it to replace it when the light device 4 is mounted on the motor vehicle. This also makes it possible to have small dimensions, in particular in width, of the light module 1 so as to be able to integrate it easily into the space between the second casing 3 and the bodywork of the motor vehicle.

Dans un mode de réalisation non limitatif illustré, l'angle β est de 90°.In one illustrated non-limiting embodiment, the angle β is 90°.

Ainsi, la première direction AX est perpendiculaire au support de source de lumière 11 et la seconde direction AY est parallèle au support de source de lumière 11 et au deuxième boîtier 3. Le fait d'avoir la partie de connexion secondaire parallèle au deuxième boîtier 3 permet d'avoir une connexion avec le connecteur extérieur 5 parallèlement au deuxième boîtier 3. Les dimensions du module lumineux 1 peuvent ainsi être réduites, notamment selon l'axe X, et le module lumineux 1 prend moins de place que si la connexion était perpendiculaire au deuxième boîtier 3 par exemple.Thus, the first direction AX is perpendicular to the light source holder 11 and the second direction AY is parallel to the light source holder 11 and the second housing 3. Having the secondary connection part parallel to the second housing 3 makes it possible to have a connection with the external connector 5 parallel to the second housing 3. The dimensions of the light module 1 can thus be reduced, in particular along the X axis, and the light module 1 takes up less space than if the connection were perpendicular to the second housing 3 for example.

Tel qu'illustré sur les figures 4b et 6b, la partie de connexion primaire 150 et la partie de connexion secondaire 151 sont reliées entre elles via un coude 152 qui permet de réaliser l'angle β. Ainsi, la broche 150a de la partie de connexion primaire 150 est reliée par un coude à la broche 151a de la partie de connexion secondaire 151, et la broche 150b de la partie de connexion primaire 150 est reliée par un coude à la broche 151b de la partie de connexion secondaire 151.As shown on the figure 4b And 6b , the primary connection part 150 and the secondary connection part 151 are interconnected via an elbow 152 which makes it possible to achieve the angle β. Thus, the pin 150a of the primary connection part 150 is connected by an elbow to the pin 151a of the secondary connection part 151, and the pin 150b of the primary connection part 150 is connected by an elbow to the pin 151b of the secondary connection part 151.

Le montage par un opérateur du module lumineux 1 sur le boîtier 3 du véhicule automobile est effectué comme suit en référence aux figures 12a à 12d. Sur les figures 12a à 12d, le deuxième mode de réalisation avec le support d'accroche 310 sur le support d'élément optique 32 du deuxième boîtier 3 est pris comme exemple non limitatif pour illustrer ledit montage.The assembly by an operator of the light module 1 on the casing 3 of the motor vehicle is carried out as follows with reference to the figures 12a to 12d . On the figures 12a to 12d , the second embodiment with the attachment support 310 on the optical element support 32 of the second housing 3 is taken as a non-limiting example to illustrate said assembly.

Dans une première étape illustrée sur la figure 12a, le module lumineux 1 est disposé par l'opérateur entre le deuxième boîtier 3 et la carrosserie du véhicule automobile. Il le tourne de sorte qu'il présente un angle par rapport à l'axe longitudinal du deuxième boîtier 3. La rotation est illustrée par la flèche référencée 60 sur la figure.In a first step illustrated on the figure 12a , the light module 1 is placed by the operator between the second housing 3 and the body of the motor vehicle. He turns it so that it has an angle with respect to the longitudinal axis of the second casing 3. The rotation is illustrated by the arrow referenced 60 in the figure.

Dans une deuxième étape illustrée sur la figure 12b, le module lumineux 1 est positionné par l'opérateur de sorte que les rainures 127 du boîtier ouvert 12 du module lumineux 1 se trouvent en regard des ergots de positionnement 300 du boîtier 3. Puis, l'opérateur pousse le module lumineux 1 en translation selon un axe (non illustré) perpendiculaire à l'axe longitudinal du deuxième boîtier 3 de sorte que les ergots de positionnement 300 du boîtier 3 s'insèrent dans lesdites rainures 127 du boîtier ouvert 12. Le module lumineux 1 est ainsi disposé dans une première position p1. Le module lumineux 1 est ainsi pré-positionné sur le deuxième boîtier 3. La translation est illustrée par la flèche référencé 61 sur la figure.In a second step illustrated on the figure 12b , the light module 1 is positioned by the operator so that the grooves 127 of the open casing 12 of the light module 1 are opposite the positioning lugs 300 of the casing 3. Then, the operator pushes the light module 1 in translation along an axis (not shown) perpendicular to the longitudinal axis of the second casing 3 so that the positioning lugs 300 of the casing 3 fit into said grooves 127 of the open casing 12. The light module 1 is thus arranged in a first position p1. The light module 1 is thus pre-positioned on the second housing 3. The translation is illustrated by the arrow referenced 61 in the figure.

Dans une troisième étape illustrée sur la figure 12c, l'opérateur tourne le module lumineux 1 de sorte qu'il effectue un mouvement de rotation. Lors de cette rotation, les ergots de positionnement 300 du deuxième boîtier 3 glissent le long des zones de guidage 128 du boîtier ouvert 12 jusqu'à arriver en butée jusqu'aux butées 128b desdites zones de guidage 128. La rotation est illustrée par la flèche référencée 62 sur la figure. Les butées 128b permettent de bloquer la fin de la rotation.In a third step illustrated on the figure 12c , the operator turns the light module 1 so that it performs a rotational movement. During this rotation, the positioning lugs 300 of the second casing 3 slide along the guide zones 128 of the open casing 12 until they come into abutment as far as the stops 128b of said guide zones 128. The rotation is illustrated by the arrow referenced 62 in the figure. The stops 128b make it possible to block the end of the rotation.

Dans une quatrième étape illustrée sur la figure 12d, la rotation du module lumineux 1 se termine lorsque la patte d'accroche 124 du boîtier ouvert 12 s'engrène sur le support d'accroche 310 du deuxième boîtier 3, et se clipse sur ledit support d'accroche 310. Ainsi, le boîtier ouvert 12 est verrouillé sur le deuxième boîtier 3. Ainsi, le dispositif d'accroche formé par la patte d'accroche 124 et le support d'accroche 310 permet d'empêcher un déverrouillage intempestif du boîtier ouvert 12 lorsque notamment le véhicule automobile roule. Le module lumineux 1 est ainsi accroché au deuxième boîtier 3. Le module lumineux 1 est ainsi disposé dans une deuxième position p2, autrement appelée position montée.In a fourth step illustrated on the figure 12d , the rotation of the light module 1 ends when the hooking lug 124 of the open box 12 meshes with the hooking support 310 of the second box 3, and clips onto said hooking support 310. Thus, the box open 12 is locked on the second casing 3. Thus, the attachment device formed by the attachment lug 124 and the attachment support 310 makes it possible to prevent inadvertent unlocking of the open casing 12 when in particular the motor vehicle is moving. The light module 1 is thus attached to the second housing 3. The light module 1 is thus arranged in a second position p2, otherwise called the mounted position.

La figure 12e illustre ainsi le module lumineux 1 qui passe de la première position p1 à la deuxième position p2.There figure 12e thus illustrates the light module 1 which passes from the first position p1 to the second position p2.
