Description

Motor vehicle light device

The present invention relates to a motor vehicle lighting device. It finds a particular, but not limiting, application in motor vehicles.

1. un boîtier avec une ouverture de sortie,
2. un premier module lumineux configuré pour réaliser une fonction d’éclairage. Le module lumineux génère un faisceau lumineux en direction de l’ouverture de sortie pour réaliser la fonction d’éclairage,
3. un deuxième module lumineux configuré pour réaliser une fonction de signalisation. Le module lumineux génère un faisceau lumineux en direction de l’ouverture de sortie pour réaliser la fonction de signalisation.

A motor vehicle light device comprises, in a manner known to those skilled in the art:

1. a housing with an exit opening,
2. a first light module configured to perform a lighting function. The light module generates a light beam in the direction of the exit aperture to perform the lighting function,
3. a second light module configured to perform a signaling function. The light module generates a light beam in the direction of the exit opening to perform the signaling function.

A disadvantage of this state of the art is that the exit opening comprises a dedicated part for lighting, and another dedicated part for signalling. Therefore, the surface of the outlet opening takes up a lot of space, which poses a problem of space.

In this context, the present invention aims to propose a luminous device for a motor vehicle which makes it possible to solve the drawback mentioned.

1. un boîtier avec une ouverture de sortie,
2. au moins un module lumineux inséré dans ledit boitier et configuré pour réaliser une fonction d’éclairage, caractérisé en ce que ledit au moins un module lumineux est solidaire avec au moins un guide de lumière configuré pour réaliser une fonction de signalisation et forme un ensemble avec ledit guide de lumière, ledit ensemble étant mobile entre une première position dans laquelle ledit au moins un module lumineux est en regard de ladite ouverture de sortie et ledit guide de lumière est en regard d’une face dudit boîtier, et une deuxième position dans laquelle ledit guide de lumière est en regard de ladite ouverture de sortie et ledit au moins un module lumineux est en regard de ladite face dudit boîtier.

To this end, the invention proposes a motor vehicle lighting device comprising:

1. a housing with an exit opening,
2. at least one light module inserted into said box and configured to perform a lighting function, characterized in that said at least one light module is integral with at least one light guide configured to perform a signaling function and forms an assembly with said light guide, said assembly being movable between a first position in which said at least one light module faces said exit opening and said light guide faces a face of said housing, and a second position in which said light guide faces said exit opening and said at least one light module faces said face of said housing.

Thus, as will be seen in detail below, the fact of being able to move said assembly between a first position and a second position makes it possible to make the light module retractable in the body of the motor vehicle so that it is no longer necessary to have in the exit opening two separate parts dedicated to lighting and signalling. Indeed, the light beam for signaling exits at the same place through the exit opening as the light beam for lighting. Consequently, the surface of the exit opening can be reduced compared to that of the state of the prior art. In addition, the light module is protected when the light function is not in use.

According to non-limiting embodiments, the light device may also comprise one or more additional characteristics taken alone or according to all the technically possible combinations, among the following.

According to a non-limiting embodiment, said light device comprises a plurality of light guides, one or more of which is integral with said at least one light module.

According to a non-limiting embodiment, said light device comprises at least one actuator configured to move said assembly between said first position and said second position.

According to a non-limiting embodiment, said light device comprises a plurality of light modules.

According to a non-limiting embodiment, said light device comprises a plurality of actuators each configured to move one of said light modules between said first position and said second position.

According to a non-limiting embodiment, said casing is without glass to close said outlet opening of said casing.

According to a non-limiting embodiment, the lighting function is a high beam or a dipped beam.

The invention and its various applications will be better understood on reading the following description and examining the accompanying figures.

there shows a diagram of a front face of a motor vehicle in which is integrated a light device comprising a housing and a light module configured to perform a lighting function and a light guide configured to perform a signaling function, said guide of light being integral with said light module, according to a non-limiting embodiment of the invention,

Identical elements, by structure or by function, appearing in different figures retain, unless otherwise specified, the same references.

A luminous device 1 of a motor vehicle 2 according to the invention is described with reference to FIGS. 1 to 3, according to non-limiting embodiments. Motor vehicle means any type of motorized vehicle. In non-limiting embodiments, the motor vehicle 2 is an electric, hybrid or combustion engine vehicle. The motor vehicle 2 is otherwise called a vehicle. The motor vehicle 2 comprises a front face 20 in which the light device 1 is integrated. In one non-limiting embodiment, the light device 1 is a front headlight of the motor vehicle 2.

1. un boîtier 10 avec une ouverture de sortie 10a,
2. un module lumineux 12 inséré dans ledit boîtier 10 et au moins un guide de lumière 13, le tout formant un ensemble 14.

As illustrated in Figure 1, the light device 1 comprises:

1. a housing 10 with an outlet opening 10a,
2. a light module 12 inserted in said housing 10 and at least one light guide 13, the whole forming an assembly 14.

In a first non-limiting embodiment, the case 10 includes a lens to close the outlet opening 10a of the case 10. In a second non-limiting embodiment, the case 10 is without a lens. This provides a style effect.

The light module 12 is configured to emit a primary light beam 12a (illustrated schematically by an arrow in Figure 1) towards the exit opening 10a of the housing 10 and which passes through said exit opening 10a. The primary light beam 12a makes it possible to perform a primary optical function f1. In a non-limiting embodiment, the primary optical function f1 is a lighting function. Thus, the light module 12 is configured to perform a lighting function f1. In this case, the light module 12 is also called a lighting module. In non-limiting embodiments, the lighting function f1 is a main beam HB called "high beam" in English language or a dipped beam LB (or code) called "low beam" in English language . In a non-limiting embodiment, the light module 12 comprises at least one output or projection lens. The light modules being known to those skilled in the art, the light module 12 is not described in detail here.

1. un clignotant TI appelé en langage anglo-saxon « Turn Indicator », et/ou
2. un feu diurne DRL appelé en langage anglo-saxon « Daytime Running Lamp », et/ou
3. un feu de parking PL appelé en langage anglo-saxon « Parking Lamp », et/ou
4. un feu de brouillard FG appelé en langage anglo-saxon « Fog lamp », et/ou
5. un feu latéral SM appelé en langage anglo-saxon « Side marker », et/ou

Said at least one light guide 13 is configured to emit a secondary light beam 13a (illustrated schematically by an arrow in FIG. 1) towards the exit opening 10a of the housing 10 and which passes through the said exit opening 10a. The secondary light beam 13a makes it possible to perform a secondary optical function f2. In a non-limiting embodiment, the secondary optical function f2 is a signaling function. Thus, the light guide 13 is configured to perform a signaling function f2. A signaling function f2 is thus integrated into the light device 1. In non-limiting embodiments, the signaling function f2 is:

1. a TI indicator called in Anglo-Saxon language “Turn Indicator”, and/or
2. a DRL daytime running light called in Anglo-Saxon language "Daytime Running Lamp", and/or
3. a HGV parking light called in Anglo-Saxon language "Parking Lamp", and/or
4. a fog lamp FG called in Anglo-Saxon language "Fog lamp", and/or
5. an SM side light called in Anglo-Saxon language “Side marker”, and/or

In a non-limiting embodiment, the light guide 13 comprises a screen. The light guides being known to those skilled in the art, the light guide 13 is not described in detail here. The light module 12 is integral with said at least one light guide 13 so as to form an assembly 14. There is no possible movement between the light module 12 and the light guide 13. In a non-limiting embodiment , said at least one light guide 13 is arranged under the light module 12. Thus, the size of the light device 1 is reduced in its width. Figure 2 illustrates a front face 20 of the motor vehicle 2 in which is integrated a light device 1 which is a front projector in the non-limiting example taken. As illustrated in FIG. 2, said at least one light guide 13 is integrated in the lower part of the front headlight of the motor vehicle 2. The signaling function f2 is thus integrated in the lower part of the front headlight of the motor vehicle 2 in the non-limiting example taken.

The assembly 14 formed by the light module 12 and by said at least one light guide 13 is movable between a first position p1 (illustrated in Figure 2) and a second position p2 (illustrated in Figure 3).

In the first position p1 illustrated in FIG. 2, the light module 12 faces the outlet opening 10a of the housing 10, while the light guide 13 faces a face 10b of the housing 10. The latter is thus completely or partially hidden by the face 10b of the housing 10. To this end, it is partly illustrated in dotted lines. It will be noted that the box 10 is integrated behind the front face 20 of the motor vehicle 2. To this end, it is largely illustrated in dotted lines. In particular, face 10b is located behind front face 20 of motor vehicle 2. Thus, assembly 14 assumes this first position p1 when lighting function f1 is activated and signaling function f2 is deactivated. This allows the primary light beam 12a to pass through the exit aperture 10a to illuminate the road on which the motor vehicle 2 is located, for example. In a non-limiting example, the assembly 14 passes into the first position p1 when the main beam 12 is on when the motor vehicle is driving at night. In another non-limiting example, the assembly 14 goes into the first position p1 when the headlights are called day or night.

It will be noted that in the non-limiting embodiment where the light guide 13 is arranged under the light module 12, when the assembly 14 moves to reach the first position p1, it performs a downward movement. In one non-limiting embodiment, the movement is a downward translational movement. The assembly 14 thus descends to reveal the light module 12 and the light guide 13 to disappear behind the face 10b of the case 10.

In the second position p2 illustrated in FIG. 3, the light guide 13 faces the outlet opening 10a of the housing 10, while the light module 12 faces the face 10b of the housing 10. The latter is thus completely or partially hidden by the face 10b of the housing 10. For this purpose, it is largely illustrated in dotted lines. It will be noted that the box 10 is integrated behind the front face 20 of the motor vehicle 2. To this end, it is partly illustrated in dotted lines. In particular, face 10b is located behind front face 20 of motor vehicle 2. Thus, assembly 14 assumes this second position p2 when signaling function f2 is activated and lighting function f1 is deactivated. This allows the secondary light beam 13a to pass through the exit opening 10a to illuminate the road on which the motor vehicle 2 is located, for example. In a non-limiting example, the assembly 14 goes into the second position p2 when the DRL daytime running lights are on when the motor vehicle is driving during the day and/or when a TI indicator is switched on. In another non-limiting example, the assembly 14 passes into the second position p2 when the motor vehicle 2 is stationary and the daytime running lights DRL switch on and off to follow a welcome scenario.

It will be noted that in the non-limiting embodiment where the light guide 13 is arranged under the light module 12, when the assembly 14 moves to reach the second position p2, it performs an upward movement. In one non-limiting embodiment, the movement is an upward translational movement. Assembly 14 thus rises to reveal light guide 13 and light module 12 to disappear behind face 10b of housing 10.

In order to move the assembly 14 between the first position p1 and the second position p2, in one non-limiting embodiment, the light device 1 further comprises at least one actuator 15 illustrated in FIG. 1. The actuator 15 thus allows to move the assembly 14 downwards or upwards and thus to retract said at least one light guide 13 (position p1) or the light module 12 (position p2) behind the face 10b of the housing 10. In one mode of non-limiting embodiment, the actuator 15 is carried by a fixed plate 16 (illustrated in Figure 1). Since the actuators are well known to those skilled in the art, the actuator 15 is not described in detail here.

In a non-limiting embodiment, the light device 1 comprises a plurality of light modules 12, each integral with at least one light guide. In the non-limiting embodiment of Figure 2, the light device 1 comprises two light modules 12. Thus, in a non-limiting example, a first light module 12 is configured to perform a lighting function f1 which is a traffic light. road, and a second light module 12 is configured to perform a lighting function f1 which is a low beam. In the non-limiting example of Figure 2, the low beam is to the left of the high beam from the point of view of a pedestrian looking at the front face 20 of the motor vehicle 2.

In the case where the light device 1 comprises a plurality of light modules 12, in a first non-limiting embodiment, the light device 1 comprises a single actuator 15 for all the light modules 12. Thus, the light modules 12 are set in motion all at the same time. They thus perform a downward or upward movement at the same time. The single actuator 15 thus makes it possible to move an assembly 14 formed by the assembly of light modules 12 and light guides 13 integral with said light modules 12. In a second non-limiting embodiment, the light device 1 comprises an actuator 15 associated with each light module 12. Thus, the light modules 12 are independent of each other and are set in motion independently. They thus perform a downward or upward movement independently of each other. Thus, in a non-limiting example, where the driver of the motor vehicle 2 flashes the headlight, the light module 12 which produces the main beam can descend to face the exit opening 10a while the light module 12 which realizes the low beam does not move and remains hidden behind the face 10b of the housing 10. The high beam is activated while the low beam is deactivated. Each actuator 15 thus makes it possible to move an assembly 14 formed by a light module 12 and at least one light guide 13 integral with said light module 12.

In a non-limiting embodiment, the light device 1 comprises several light guides 13, one or more of which is integral with said light module 12. Thus, in the non-limiting embodiment of Figure 3 where there are two light modules 12 , the light device 1 comprises three light guides 13, two of which are integral with the first light module 12 (here the driving light on the right in the non-limiting example taken), and one is integral with the second light module 12 (here the low beam on the left in the non-limiting example taken).

Of course, the description of the invention is not limited to the application and to the embodiments described above.

1. elle permet de protéger le module lumineux 12 quand il n’est pas en fonctionnement, notamment en cas d’absence de glace (permettant de fermer l’ouverture de sortie 10a du boîtier 10) sur le boîtier 10. Cela le protège des chocs ou encore des contacts avec des piétons. Cela évite aux piétons de toucher avec leurs mains le module lumineux 12. Ainsi, cela évite d’abîmer le module lumineux 12. Ainsi, lorsque la fonction d’éclairage est désactivée, ledit module lumineux 12 correspondant est protégé contre d’éventuelles agressions extérieures. Il n’est en effet pas accessible.
2. de la même manière, elle permet de protéger ledit au moins un guide de lumière 13 quand il n’est pas en fonctionnement.
3. elle permet d’obtenir deux fonctions optiques dans un même dispositif lumineux 1, à savoir dans l’exemple non limitatif pris une fonction d’éclairage f1 et une fonction de signalisation f2 dans un même dispositif lumineux 1. Cela permet de réduire l’espace utilisé pour réaliser ces deux fonctions optiques. Cela permet également d’avoir une signature visuelle différente par rapport à d’autres véhicules automobiles et d’obtenir une différentiation esthétique par rapport à d’autres véhicules automobiles.

Thus, the invention described has in particular the following advantages.

1. it makes it possible to protect the light module 12 when it is not in operation, in particular in the event of the absence of ice (allowing the outlet opening 10a of the case 10 to be closed) on the case 10. This protects it from shocks or still contact with pedestrians. This prevents pedestrians from touching the light module 12 with their hands. Thus, this avoids damaging the light module 12. Thus, when the lighting function is deactivated, said corresponding light module 12 is protected against possible external attacks. . It is indeed not accessible.
2. in the same way, it makes it possible to protect said at least one light guide 13 when it is not in operation.
3. it makes it possible to obtain two optical functions in the same light device 1, namely in the non-limiting example taken a lighting function f1 and a signaling function f2 in the same light device 1. This makes it possible to reduce the space used to achieve these two optical functions. This also makes it possible to have a different visual signature compared to other motor vehicles and to obtain an aesthetic differentiation compared to other motor vehicles.
