Ceci est en particulier le cas lorsque la source de lumière est du type à diode électroluminescente. On peut ainsi obtenir des dispositifs d'éclairage performants. Cependant, de tels dispositifs présentent des inconvénients. Ils ont des structures complexes et sont donc compliqués à assembler. En outre, il est nécessaire de mettre en place des tolérances sur de nombreuses pièces qui doivent être montées les unes avec les autres. Les chaînes de cotes des différentes pièces sont donc également complexes dans ces dispositifs.It is known, for example, from documents US 2009/303 742 And WO 2005/116 520 to produce lighting devices in which the light source is mounted on a radiator onto which an air flow is directed, so that part of the heat produced by the light source is dissipated by the radiator into the air flow. This is particularly the case when the light source is of the light-emitting diode type. This makes it possible to obtain high-performance lighting devices. However, such devices have disadvantages. They have complex structures and are therefore complicated to assemble. In addition, it is necessary to establish tolerances on many parts that must be mounted together. The dimension chains of the individual parts are therefore also complex in these devices.

Un module optique comprenant les caractéristiques du préambule de la revendication 1 est connu par exemple du document DE 10 2007 043961 A1 .An optical module comprising the features of the preamble of claim 1 is known for example from document DE 10 2007 043961 A1 .

Le but de l'invention est de fournir un module optique de dispositif d'éclairage et/ou de signalisation remédiant aux inconvénients précédemment mentionnés et améliorant les modules optiques connus de l'art antérieur. En particulier, l'invention propose un module optique de structure simple et dans lequel les chaînes de cotes sont également simples.The aim of the invention is to provide an optical module for a lighting and/or signaling device which overcomes the previously mentioned drawbacks and improves the optical modules known from the prior art. In particular, the invention provides an optical module of simple structure and in which the dimension chains are also simple.

Ces objectifs sont atteints avec un module optique selon la revendication 1.These objectives are achieved with an optical module according to claim 1.

Selon un mode de réalisation non revendiqué, le module optique de dispositif d'éclairage et/ou de signalisation d'un véhicule automobile, comprend un support, une lentille optique et un échangeur thermique. La lentille optique et l'échangeur thermique sont fixés audit support et le support relie la lentille optique à l'échangeur thermique. De préférence, le support supporte directement la lentille et supporte directement l'échangeur thermique. Ainsi, il est possible de réaliser un module optique simple et facile à assembler, les chaînes de cotes des différents composants étant elles aussi simples.According to an unclaimed embodiment, the optical module of a lighting and/or signaling device of a motor vehicle comprises a support, an optical lens and a heat exchanger. The optical lens and the exchanger thermal are fixed to said support and the support connects the optical lens to the heat exchanger. Preferably, the support directly supports the lens and directly supports the heat exchanger. Thus, it is possible to produce a simple and easy-to-assemble optical module, the dimension chains of the various components also being simple.

Le support peut être destiné à être monté directement ou indirectement sur le boîtier du dispositif d'éclairage et/ou de signalisation et à l'intérieur de ce boîtier.The bracket may be intended to be mounted directly or indirectly on the housing of the lighting and/or signaling device and inside this housing.

Le support peut également supporter un ventilateur et/ou au moins un réflecteur de lumière et/ou une plieuse et/ou un moyen de canalisation d'air. De préférence, le support supporte directement le ventilateur et/ou l'au moins un réflecteur de lumière et/ou la plieuse et/ou le moyen de canalisation d'air. Ainsi, le module optique est encore simplifié et son assemblage est encore facilité.The support may also support a fan and/or at least one light reflector and/or a folder and/or an air channeling means. Preferably, the support directly supports the fan and/or the at least one light reflector and/or the folder and/or the air channeling means. Thus, the optical module is further simplified and its assembly is further facilitated.

Le support peut comprendre des moyens de positionnement de la lentille optique et/ou du ventilateur et/ou de l'au moins un réflecteur de lumière et/ou de la plieuse et/ou de l'échangeur thermique, ces moyens coopérant avec des moyens de positionnement prévus sur la lentille optique et/ou sur le ventilateur et/ou sur l'au moins un réflecteur de lumière et/ou sur la plieuse et/ou sur l'échangeur thermique.The support may comprise means for positioning the optical lens and/or the fan and/or the at least one light reflector and/or the folder and/or the heat exchanger, these means cooperating with positioning means provided on the optical lens and/or on the fan and/or on the at least one light reflector and/or on the folder and/or on the heat exchanger.

Le module optique peut comprendre une première et une deuxième sources de lumière destinées à assurer deux fonctions distinctes d'éclairage et/ou de signalisation.

Ainsi, il est possible d'orienter l'axe du module optique en fonction de courbes négociées par le véhicule.The support may be capable of being mounted in rotation in a housing of a lighting and/or signaling device of a motor vehicle. Thus, it is possible to orient the axis of the optical module according to curves negotiated by the vehicle.

Le module optique peut comprendre une embase destinée à être fixée au boîtier de dispositif d'éclairage et/ou de signalisation du véhicule automobile et comprenant des premiers moyens d'articulation destinés à être solidarisés au support de sorte à permettre la rotation du support par rapport au boîtier. Par exemple, le support peut comprendre un tenon destiné à coopérer avec un orifice de l'embase, par exemple un tenon au sommet du support et un en dessous, l'axe passant par ces tenons correspondant à l'axe de rotation du module par rapport au boîtier.The optical module may comprise a base intended to be fixed to the housing of the lighting and/or signaling device of the motor vehicle and comprising first articulation means intended to be secured to the support so as to allow rotation of the support relative to the housing. For example, the support may comprise a tenon intended to cooperate with an orifice of the base, for example a tenon at the top of the support and one below, the axis passing through these tenons corresponding to the axis of rotation of the module relative to the housing.

L'embase peut comprendre un mécanisme de manœuvre destiné à orienter le support relativement au boîtier. Selon un exemple de réalisation, l'embase peut comprendre un mécanisme d'entraînement, d'où sort un axe d'entraînement coopérant avec un orifice du module, préférentiellement du support, de manière à entraîner le support en rotation. En variante, et tel qu'illustré, le support peut être indirectement relié à l'embase par une pièce intermédiaire, par exemple un cadre. Le support peut alors comprendre des pattes de fixation fixées au cadre. Le cadre comprend dans ce cas les moyens coopérant avec les premiers moyens d'articulation de l'embase, par exemple un tenon en haut et un orifice en bas, le tenon tournant dans l'orifice supérieur de l'embase et l'orifice recevant l'axe d'entraînement.The base may comprise an operating mechanism intended to orient the support relative to the housing. According to an exemplary embodiment, the base may comprise a drive mechanism, from which emerges a drive shaft cooperating with an orifice of the module, preferably of the support, so as to drive the support in rotation. Alternatively, and as illustrated, the support may be indirectly connected to the base by an intermediate part, for example a frame. The support may then comprise fixing lugs fixed to the frame. The frame in this case comprises the means cooperating with the first articulation means of the base, for example a tenon at the top and an orifice at the bottom, the tenon rotating in the upper orifice of the base and the orifice receiving the drive shaft.

La lentille optique peut être positionnée et fixée au support dans la partie avant de ce dernier et l'échangeur thermique peut être positionné et fixé au support sous ce dernier.The optical lens can be positioned and fixed to the bracket in the front part of the latter and the heat exchanger can be positioned and fixed to the bracket below the latter.

Compte tenu de la structure des systèmes optiques décrits précédemment, on comprend qu'il est important que les différents composants des systèmes optiques, à savoir : sources de lumière, réflecteurs, plieuse et lentille optique soient positionnés précisément les uns par rapport aux autres. Pour ce faire, plusieurs solutions existent. Notamment, on peut positionner la lentille par rapport au support, positionner les réflecteurs par rapport au support, positionner les sources de lumière par rapport au radiateur et positionner le radiateur par rapport au support. Dans cet exemple, la chaîne de cotes positionnant les sources de lumière par rapport aux réflecteurs ou par rapport à la lentille optique passent par le radiateur et le support. Alternativement, on peut positionner la lentille par rapport au support, positionner les réflecteurs par rapport au radiateur, positionner les sources de lumière par rapport au radiateur et positionner le radiateur par rapport au support. Dans ce dernier exemple, la chaîne de cotes positionnant les sources de lumière par rapport aux réflecteurs ne passent plus que par le radiateur.Given the structure of the optical systems described above, it is understood that it is important that the various components of the optical systems, namely: light sources, reflectors, folder and optical lens are positioned precisely relative to each other. To achieve this, several solutions exist. In particular, one can position the lens relative to the support, position the reflectors relative to the support, position the light sources relative to the radiator and position the radiator relative to the support. In this example, the dimension chain positioning the light sources relative to the reflectors or relative to the optical lens passes through the radiator and the support. Alternatively, one can position the lens relative to the support, position the reflectors relative to the radiator, position the light sources relative to the radiator and position the radiator relative to the support. In this last example, the dimension chain positioning the light sources relative to the reflectors now only passes through the radiator.

Avantageusement, dans toutes les variantes, les différents composants des systèmes optiques sont supportés par le support indirectement ou, de préférence, directement.Advantageously, in all variants, the various components of the optical systems are supported by the support indirectly or, preferably, directly.

Le ventilateur permet de créer un flux d'air 22 s'écoulant entre des ailettes 18 du radiateur et canalisé par un guide 13 pour optimiser l'échange thermique entre l'air et le radiateur.The fan creates an air flow 22 flowing between fins 18 of the radiator and channeled by a guide 13 to optimize the heat exchange between the air and the radiator.

De préférence, les différents circuits imprimés portant les diodes électroluminescentes sont fixés sur le radiateur et positionnés par rapport au radiateur. Ils sont donc indirectement supportés par le support 2, le radiateur étant fixé sur le support.Preferably, the various printed circuits carrying the light-emitting diodes are fixed to the radiator and positioned relative to the radiator. They are therefore indirectly supported by the support 2, the radiator being fixed to the support.

Le support présente par ailleurs des moyens de fixation permettant sa fixation à une structure du véhicule automobile. De préférence, les moyens de fixation permettent sa fixation dans un boîtier de dispositif d'éclairage et/ou de signalisation, ce boîtier présentant par ailleurs des moyens de fixation à la structure du véhicule automobile. Le support est de préférence réalisé par moulage. Il est par exemple réalisé en métal ou en plastique, notamment en composite.The support also has fixing means allowing it to be fixed to a structure of the motor vehicle. Preferably, the fixing means allow it to be fixed in a lighting and/or signaling device housing, this housing also having means for fixing to the structure of the motor vehicle. The support is preferably made by molding. It is for example made of metal or plastic, in particular composite.

Un deuxième mode de réalisation du module optique selon l'invention est décrit ci-après en référence aux figures 4 et 5. Il ne diffère du premier mode de réalisation que dans la structure du support 2. En effet, dans ce deuxième mode de réalisation, le support 2 comprend des premiers moyens d'articulation 2c qui coopère avec des deuxièmes moyens d'articulation sur une embase 2b destinée à être fixée dans un boîtier du dispositif d'éclairage et/ou de signalisation. Ainsi, le support et donc le module optique peut être orienté relativement au boîtier. L'embase forme par exemple un cadre dans lequel le support est articulé. Cette articulation est par exemple réalisée selon un axe vertical, par exemple par une liaison pivot. Ainsi, une fonction de modification de la direction de l'axe optique du dispositif d'éclairage et/ou de signalisation peut être réalisée lorsque le véhicule automobile négocie une courbe. L'embase peut aussi comprendre un moyen de manœuvre comme un motoréducteur permettant de piloter l'orientation du support et donc celle du module optique.A second embodiment of the optical module according to the invention is described below with reference to Figures 4 and 5 . It differs from the first embodiment only in the structure of the support 2. Indeed, in this second embodiment, the support 2 comprises first articulation means 2c which cooperate with second articulation means on a base 2b intended to be fixed in a housing of the lighting and/or signaling device. Thus, the support and therefore the optical module can be oriented relative to the housing. The base forms for example a frame in which the support is articulated. This articulation is for example carried out along a vertical axis, for example by a pivot connection. Thus, a function of modifying the direction of the optical axis of the lighting and/or signaling device can be performed when the motor vehicle negotiates a curve. The base can also include an operating means such as a geared motor making it possible to control the orientation of the support and therefore that of the optical module.

Par exemple, le support peut comprendre comme premiers moyens d'articulation un tenon (non représenté), par exemple un tenon au sommet du support et un tenon en dessous, l'axe passant par ces tenons correspondant à l'axe de rotation du module par rapport au boîtier. L'embase peut comprendre comme deuxièmes moyens d'articulation des orifices destinés à coopérer avec les tenons.For example, the support may comprise as first articulation means a tenon (not shown), for example a tenon at the top of the support and a tenon below, the axis passing through these tenons corresponding to the axis of rotation of the module relative to the housing. The base may comprise as second articulation means orifices intended to cooperate with the tenons.

Selon une variante, l'embase 2b comprend un mécanisme d'entraînement, d'où sort un axe d'entraînement 2d coopérant avec un orifice du module, préférentiellement du support 2, de manière à entraîner le support 2 en rotation. En variante, et tel qu'illustré, le support 2 peut être indirectement relié à l'embase 2b par une pièce intermédiaire (non représentée par souci de clarté), par exemple un cadre. Le support peut alors comprendre des pattes de fixation 2e fixées au cadre. Le cadre comprend alors des moyens coopérant avec les deuxièmes moyens d'articulation de l'embase, par exemple un tenon en haut et un orifice en bas, le tenon tournant dans l'orifice supérieur 2c de l'embase et l'orifice recevant l'axe d'entrainement 2d.According to a variant, the base 2b comprises a drive mechanism, from which a drive shaft 2d emerges cooperating with an orifice of the module, preferably of the support 2, so as to drive the support 2 in rotation. Alternatively, and as illustrated, the support 2 may be indirectly connected to the base 2b by an intermediate part (not shown for the sake of clarity), for example a frame. The support may then comprise fixing lugs 2e fixed to the frame. The frame then comprises means cooperating with the second articulation means of the base, for example a tenon at the top and an orifice at the bottom, the tenon rotating in the upper orifice 2c of the base and the orifice receiving the drive shaft 2d.

Dans tout ce document, on entend, par « supporter un composant », l'action de reprendre les efforts exercés sur le composant et de les transmettre à la structure du véhicule automobile, les efforts étant notamment ceux, à distance, dus à des forces d'accélération comme le poids. En outre, une pièce supportant « directement » un composant reprend directement les efforts exercés sur le composant et les transmet à la structure du véhicule automobile, c'est-à-dire qu'il n'y a pas de pièce intermédiaire transmettant les efforts entre le composant et la pièce. Alternativement, une pièce intermédiaire peut être prévue si sa seule fonction est une fonction d'interface. Dans ce dernier cas, malgré la pièce intermédiaire, on considère que la pièce supporte directement le composant.Throughout this document, the term "supporting a component" means the action of absorbing the forces exerted on the component and transmitting them to the structure of the motor vehicle, the forces being in particular those, at a distance, due to acceleration forces such as weight. In addition, a part "directly" supporting a component directly absorbs the forces exerted on the component and transmits them to the structure of the vehicle automotive, that is, there is no intermediate part transmitting forces between the component and the part. Alternatively, an intermediate part may be provided if its only function is an interface function. In the latter case, despite the intermediate part, the part is considered to directly support the component.

Dans les différents modes de réalisation, le module optique assure une première fonction feu de croisement et une deuxième fonction feu de route. Cependant, le module optique selon l'invention peut assurer toute autre fonction en remplacement de l'une et/ou de l'autre des première et deuxième fonctions. Le module optique selon l'invention peut également n'assurer qu'une seule fonction d'éclairage et/ou de signalisation, comme une fonction antibrouillard.In the various embodiments, the optical module provides a first dipped beam function and a second main beam function. However, the optical module according to the invention may provide any other function as a replacement for one and/or the other of the first and second functions. The optical module according to the invention may also provide only one lighting and/or signaling function, such as a fog light function.

Dans tout ce texte, le terme « au moins sensiblement » utilisé avec différents adjectifs signifie : « adjectif » ou « sensiblement adjectif », par exemple « au moins sensiblement perpendiculaire » signifie « perpendiculaire » ou « sensiblement perpendiculaire ».Throughout this text, the term "at least substantially" used with different adjectives means: "adjective" or "substantially adjective", for example "at least substantially perpendicular" means "perpendicular" or "substantially perpendicular".
