Description

La présente invention concerne les sources lumineuses, en particulier pour dispositif d'éclairage et/ou de signalisation d'un véhicule automobile, de type diodes électroluminescentes organiques, appelées OLED dans ce qui suit.The present invention relates to light sources, in particular for a lighting and / or signaling device of a motor vehicle, of the organic light-emitting diode type, called OLEDs in what follows.

Elle concerne plus particulièrement la connexion électrique d'une OLED d'un dispositif d'éclairage à un élément extérieur tel qu'un réseau d'alimentation électrique du véhicule automobile.It relates more particularly to the electrical connection of an OLED of a lighting device to an external element such as an electrical supply network of the motor vehicle.

Les sources de lumière utilisées pour l'éclairage et la signalisation dans les véhicules automobiles sont de plus en plus fréquemment constituées par des diodes électroluminescentes, notamment pour des avantages d'encombrement et d'autonomie par rapport à des sources de lumière classiques. L'utilisation de diodes électroluminescentes dans les modules d'éclairage et/ou de signalisation a permis en outre aux acteurs du marché (fabricants d'automobiles et concepteurs de dispositifs d'éclairage et/ou de signalisation) d'apporter une touche créative à la conception de ces dispositifs, notamment pour l'utilisation d'un nombre toujours plus grand de ces diodes électroluminescentes pour réaliser des effets optiques.The light sources used for lighting and signaling in motor vehicles are more and more frequently made up of light-emitting diodes, in particular for the advantages of size and range compared to conventional light sources. The use of electroluminescent diodes in lighting and / or signaling modules has also enabled market players (automobile manufacturers and designers of lighting and / or signaling devices) to bring a creative touch to the design of these devices, in particular for the use of an ever greater number of these light-emitting diodes to achieve optical effects.

Certains dispositifs lumineux pour véhicules automobiles tirent également partie de la technologie OLED, dont l'attrait principal est la réalisation de formes complexes améliorant l'aspect esthétique du dispositif et de l'éclairage. Des dispositifs lumineux comprenant une source OLED ont notamment été utilisés pour des fonctions de feu de position arrière.Certain lighting devices for motor vehicles also take advantage of OLED technology, the main attraction of which is the realization of complex shapes improving the aesthetic appearance of the device and of the lighting. Light devices comprising an OLED source have in particular been used for rear position light functions.

La connexion entre cathode et anode de l'OLED est généralement réalisée via un circuit imprimé flexible, ou fPCB par la suite, pour « flexible Printed Circuit Board » en anglais.The connection between cathode and anode of the OLED is generally made via a flexible printed circuit, or fPCB hereinafter, for “flexible Printed Circuit Board ” in English.

Par exemple, la figure 1 illustre un OLED 100 selon l'art antérieur. Un fBCP 101 est relié à l'anode et à la cathode de l'OLED. La connexion avec l'alimentation électrique du véhicule automobile est réalisée par soudure d'un premier fil 102.1 et d'un deuxième fil 102.3, le premier fil 102.1 étant rapporté sur l'anode, et le deuxième fil 102.2 étant rapporté sur la cathode, par exemple.For example, the figure 1 illustrates an OLED 100 according to the prior art. An fBCP 101 is connected to the anode and cathode of the OLED. The connection with the power supply of the motor vehicle is made by welding a first wire 102.1 and a second wire 102.3, the first wire 102.1 being attached to the anode, and the second wire 102.2 being attached to the cathode, for example.

Le fPCB 101 est généralement fin et la liaison par soudure est fragile.The fPCB 101 is generally thin and the solder bond is brittle.

Il existe donc un besoin d'une connexion assurant un contact électrique de façon mécanique, sans soudure, et de manière robuste. EP 3.026.761 divulgue une source lumineuse selon le préambule de la revendication 1.There is therefore a need for a connection ensuring electrical contact mechanically, without welding, and in a robust manner. EP 3,026,761 discloses a light source according to the preamble of claim 1.

La présente invention vient améliorer la situation.The present invention improves the situation.

Un premier aspect de l'invention concerne une source lumineuse comprenant :

  • une diode électroluminescente organique ;
  • une portion de connexion électronique apte à permettre l'alimentation électrique de ladite diode électroluminescente organique ;
  • un connecteur apte à recevoir une alimentation électrique depuis un élément extérieur ;
  • un moyen de plaquage du connecteur sur la portion de connexion.
A first aspect of the invention relates to a light source comprising:
  • an organic light emitting diode;
  • an electronic connection portion capable of enabling the power supply of said organic light-emitting diode;
  • a connector adapted to receive an electric power supply from an external element;
  • a means for plating the connector on the connection portion.

Une liaison mécanique est ainsi opérée sur la portion de connexion électronique avec un connecteur. Il est ainsi rendu possible de créer un connecteur dont une extrémité non reliée à la portion de connexion est facilement connectable à un élément extérieur à la source lumineuse, tel qu'un circuit d'alimentation par exemple. Selon l'invention, la portion de connexion est un circuit imprimé flexible formant une anode et une cathode de la diode électroluminescente organique.A mechanical connection is thus made on the electronic connection portion with a connector. It is thus made possible to create a connector, one end of which is not connected to the connection portion is easily connectable to an element external to the light source, such as a power supply circuit for example. According to the invention, the connection portion is a flexible printed circuit forming an anode and a cathode of the organic light-emitting diode.

Selon un mode de réalisation, le connecteur peut comprendre des languettes de connexion à l'élément extérieur.According to one embodiment, the connector may include tabs for connection to the external element.

L'utilisation d'une languette, ayant une dimension supérieure aux deux autres dimensions dans l'espace, permet d'obtenir un connecteur aisément accessible, ce qui est particulièrement avantageux, notamment dans un environnement contraint tel qu'un phare de véhicule automobile.The use of a tab, having a dimension greater than the other two dimensions in space, makes it possible to obtain an easily accessible connector, which is particularly advantageous, in particular in a constrained environment such as a motor vehicle headlight.

En complément, la source lumineuse peut comprendre deux languettes de connexion, une première languette de connexion étant destinée à être reliée à l'anode et une deuxième languette de connexion étant destinée à être reliée à la cathode.In addition, the light source can comprise two connection tabs, a first connection tab being intended to be connected to the anode and a second connection tab being intended to be connected to the cathode.

Ainsi, à la fois l'anode et la cathode peuvent être reliées aisément à l'élément extérieur.Thus, both the anode and the cathode can be easily connected to the outer member.

En complément ou en variante, les languettes de connexion peuvent avoir des tailles ou des formes différentes.In addition or alternatively, the connection tabs may have different sizes or shapes.

Un tel mode de réalisation permet de différencier aisément les languettes, facilitant ainsi le raccordement de la source lumineuse à l'élément extérieur pouvant être un circuit d'alimentation.Such an embodiment makes it possible to easily differentiate the tabs, thus facilitating the connection of the light source to the external element which can be a supply circuit.

Selon un mode de réalisation, le moyen de plaquage peut être apte à encapsuler au moins partiellement la diode électroluminescente organique de manière à presser chaque languette contre la portion de connexion.According to one embodiment, the plating means may be able to at least partially encapsulate the organic light-emitting diode so as to press each tab against the connection portion.

Ainsi, les éléments de la source lumineuse sont reliés mécaniquement, améliorant la robustesse de la liaison entre les languettes et la portion de connexion.Thus, the elements of the light source are mechanically connected, improving the strength of the connection between the tabs and the connection portion.

En complément, le moyen de plaquage peut comprendre une première partie et une deuxième partie, les première et deuxième parties étant aptes à être assemblées de manière à réaliser l'encapsulation de la diode électroluminescente organique.In addition, the plating means can comprise a first part and a second part, the first and second parts being able to be assembled so as to achieve the encapsulation of the organic light-emitting diode.

Ainsi, l'utilisation de deux parties permet de faciliter l'assemblage des éléments de la source lumineuse.Thus, the use of two parts makes it possible to facilitate the assembly of the elements of the light source.

Encore en complément, les première et deuxième parties peuvent être reliées par une charnière.Still further, the first and second parts can be connected by a hinge.

Il est ainsi possible de désengager l'OLED du moyen de plaquage, afin de la remplacer par exemple.It is thus possible to disengage the OLED from the plating means, in order to replace it for example.

En complément ou en variante, le moyen de plaquage peut encapsuler intégralement la diode électroluminescente organique.Additionally or alternatively, the plating means may fully encapsulate the organic light emitting diode.

La protection de l'OLED est ainsi assurée. Par exemple, le matériau du moyen de plaquage peut être étanche assurant ainsi l'étanchéité de la source lumineuse.The protection of the OLED is thus ensured. For example, the material of the plating means can be waterproof, thus ensuring the tightness of the light source.

Selon un mode de réalisation, le connecteur comprend un premier moyen de positionnement et le moyen de plaquage comprend un deuxième moyen de positionnement, les premier et deuxième moyens de positionnement étant complémentaires de manière à positionner le connecteur dans une position prédéterminée sur la portion de connexion.According to one embodiment, the connector comprises a first positioning means and the plating means comprises a second positioning means, the first and second positioning means being complementary so as to position the connector in a predetermined position on the connection portion .

Ainsi, il est rendu possible d'assembler avec précision, de manière simple, la source lumineuse.Thus, it is made possible to assemble with precision, in a simple manner, the light source.

Par exemple:

  • le premier moyen de positionnement comprend un plot et le deuxième moyen de positionnement comprend un trou complémentaire du plot ; ou
  • le deuxième moyen de positionnement comprend un plot et le premier moyen de positionnement comprend un trou complémentaire du plot.
For example:
  • the first positioning means comprises a stud and the second positioning means comprises a hole complementary to the stud; or
  • the second positioning means comprises a stud and the first positioning means comprises a hole complementary to the stud.

En complément ou en variante, le connecteur peut comprendre au moins deux premiers moyens de positionnement et le moyen de plaquage comprend au moins deux deuxièmes moyens de positionnement, les premier et deuxième moyens de positionnement étant complémentaires de manière à positionner et bloquer en rotation le connecteur dans une position prédéterminée sur la portion de connexion.In addition or as a variant, the connector can comprise at least two first positioning means and the plating means comprises at least two second positioning means, the first and second positioning means being complementary so as to position and block the connector in rotation. in a predetermined position on the connection portion.

Ainsi, la source lumineuse est stable et robuste et peut être connectée avec précision à l'élément extérieur.Thus, the light source is stable and robust and can be accurately connected to the outdoor element.

Selon un mode de réalisation, le connecteur peut comprendre de l'or et la portion de connexion électronique comprend un alliage nickel-or. En variante, le connecteur peut comprendre de l'étain et la portion de connexion électronique comprend de l'étain.According to one embodiment, the connector may comprise gold and the electronic connection portion comprises a nickel-gold alloy. Alternatively, the connector can include tin and the electronic connection portion includes tin.

Dans les deux cas, on évite avantageusement toute migration d'électrons ou corrosion de la source lumineuse.In both cases, any electron migration or corrosion of the light source is advantageously avoided.

Un deuxième aspect de l'invention concerne un module lumineux pour véhicule automobile comprenant au moins une source lumineuse selon le premier aspect de l'invention.A second aspect of the invention relates to a light module for a motor vehicle comprising at least one light source according to the first aspect of the invention.

Selon un mode de réalisation, le module lumineux comprend au moins une première source lumineuse comprenant un premier connecteur et une deuxième source lumineuse comprenant un deuxième connecteur, et les premier et deuxième connecteurs ont des tailles ou formes respectives différentesAccording to one embodiment, the light module comprises at least a first light source comprising a first connector and a second light source comprising a second connector, and the first and second connectors have different respective sizes or shapes.

Il est ainsi aisé de différencier les sources lumineuses par leurs connecteurs et les sources lumineuses peuvent ainsi avoir des caractéristiques différentes sans risquer de faire une erreur dans le raccordement des sources lumineuses à l'élément extérieur pouvant être un circuit d'alimentation.It is thus easy to differentiate the light sources by their connectors and the light sources can thus have different characteristics without running the risk of making an error in the connection of the light sources to the external element which may be a supply circuit.

En complément, le premier connecteur de la première source lumineuse comprend une première languette de connexion et une deuxième languette de connexion, et le deuxième connecteur de la deuxième source lumineuse comprend une troisième languette de connexion et une quatrième languette de connexion et un premier espacement entre la première languette de connexion et la deuxième languette de connexion est différent d'un deuxième espacement entre la troisième languette de connexion et la quatrième languette de connexion.Additionally, the first connector of the first light source includes a first connector tab and a second connector tab, and the second connector of the second light source includes a third connector tab and a fourth connector tab and a first spacing between the first connection tab and the second connection tab is different from a second spacing between the third connection tab and the fourth connection tab.

Il n'est ainsi pas possible d'intervertir les connexions des sources lumineuses à l'élément extérieur.It is thus not possible to interchange the connections of the light sources to the exterior element.
