Description

Title of the invention: Lighting assembly for the implementation of a road vehicle position light signal

[0001] The present invention relates to the field of lighting devices intended to be positioned on the front of road vehicles and more particularly to the field of devices enabling lighting of the central or median part of the front of such vehicles.

[0002] Road vehicles incorporate lighting devices, particularly on their front and rear ends. These devices primarily serve a safety purpose by projecting light in the direction of the vehicle's movement to optimize driver visibility (high beams, low beams) and projecting light signals to inform the vehicle's surroundings about its movement (position lights, turn signals, etc.). Furthermore, as vehicle designs evolve, a trend is emerging towards providing lighting that highlights elements mounted in the central part of the vehicle.Thus, some vehicle designs incorporate lighting devices that function similarly to parking lights to illuminate a graphic element such as the vehicle manufacturer's emblem or brand, traditionally positioned on the front of the vehicle or its hood, at its centerline. Such lighting devices can also be arranged to highlight other elements of the vehicle's front end, such as the grille, the design of which is often specific to the brand or model range.

[0003] In the design and construction of a vehicle, the arrangement of the light surfaces on the various faces of the vehicle must comply with a strict set of standards and regulatory constraints. The luminous intensity required for these supplementary lights to illuminate elements in the central part at the front of the vehicle is similar to that of the position lights, so that currently, only these position lights are likely to be considered for providing this supplementary lighting. From a regulatory standpoint, provided that the light surfaces in operation are not separated by more than 75 millimeters, there is no objection to these lights extending to the vehicle's centerline.However, it is imperative that a lateral end of the lighting assembly of the device performing the positioning function be positioned within 400 millimeters of the vehicle's overall lateral dimensions. Generally, . The end of a vehicle's grille is located well beyond the 400 millimeters of the overall side measurement. Lighting this grille is therefore technically complex, if not impossible. Even more so, the same applies to lighting an emblem or brand name placed on the vehicle's or grille's longitudinal centerline, that is, at a maximum distance from the overall side measurement.

[0004] To overcome the constraint imposing a maximum distance of 75 millimeters between two illuminated surfaces, a regulatory alternative allows the various illuminated surfaces to be arranged arbitrarily within the same quadrilateral encompassing them, provided that these illuminated surfaces cover at least 60% of the area of ​​this quadrilateral. This permitted construction alternative nevertheless remains restrictive by imposing a minimum light coverage, thus also limiting the possibilities for illuminated designs of vehicle front ends.

[0005] The present invention aims to overcome these drawbacks by proposing a lighting device which allows for the projection of light at the level of the central part, or even the middle part of the front of a vehicle, while meeting the regulatory constraints in force at the date of filing of this document.

[0006] The invention thus relates to a lighting system for producing a position light signal on at least one lateral half of the front face of a road vehicle, comprising: - a plurality of luminous surfaces, - a support structure for positioning the light production equipment for creating each of the illuminated surfaces of the lighting system, characterized in that the different luminous surfaces of the lighting system correspond to at least: - a first central set of luminous surfaces positioned in a central part of the front of the vehicle, - a second lateral assembly comprising at least one luminous surface dedicated to the dipped beam headlights and / or at least one luminous surface dedicated to the cornering lights and / or at least one luminous surface dedicated to the main beam headlights of the vehicle, this second lateral assembly being configured such that at least one luminous surface of the second assembly comprises, on the one hand, at least one lateral end positioned less than 400 millimeters from the overall lateral dimension of the vehicle and, on the other hand, a medial end positioned beyond 400 millimeters from the overall lateral dimension of the vehicle, so that, on the one hand, the lateral end of the first central set of luminous surfaces is positioned at most 75 millimeters from the medial end of the luminous surface of the second lateral set and that, on the other hand, the first central set is configured to be operated jointly with the second lateral set in the form of a set of operated luminous surfaces spaced at most 75 millimeters apart.

[0007] The invention also relates to a vehicle equipped with at least one pair of lighting assemblies according to the invention, characterized in that the lighting assemblies are mounted on the front of the vehicle, symmetrically on either side of the median longitudinal vertical plane of the vehicle.

[0008] The invention also relates to a method of operating a lighting assembly according to the invention, characterized in that the method comprises a step of jointly actuation, on the one hand, of the first central set of luminous surfaces and, on the other hand, of at least one luminous surface of the second lateral set, by modulation of the luminous intensity emitted by each of the actuated luminous surfaces.

[0009] The invention will be better understood from the following description, which relates to preferred embodiments, given by way of non-limiting example, and explained with reference to the accompanying schematic drawings, in which: - [Fig. 1] represents a schematic illustration of an example of a lighting assembly according to the invention for producing a position light signal on one lateral half of the front face of a vehicle, - [Fig.2] represents a schematic illustration of a second example of a lighting assembly according to the invention for producing a position light signal on a lateral half of the front face of a vehicle.

[0010] The present invention relates to a lighting assembly for providing a position light signal on at least one lateral half of the front face 2 of a road vehicle, comprising: - a plurality of luminous surfaces 111, 121, 122, 123, - a support structure 21 for the positioning of production resources of light for the realization of each of the luminous surfaces 111, 121, 122, 123 of the lighting assembly, characterized in that the different luminous surfaces 111, 121, 122, 123 of the lighting assembly correspond to at least: - a first central assembly 11 of luminous surfaces 111 positioned in a central part of the front face 2 of the vehicle, - a second lateral assembly 12 comprising at least one luminous surface dedicated to the dipped headlights 121 and / or at least one luminous surface dedicated to the cornering lights 122 and / or at least one luminous surface dedicated to the high beams 123 of the vehicle, this second lateral assembly 12 being configured such that the at least one luminous surface 121, 122, 123 of the second assembly 12 comprises, on the one hand, at least one lateral end 124 positioned less than 400 millimeters from the overall lateral dimension 23 of the vehicle and, on the other hand, a medial end 125 positioned beyond 400 millimeters from the overall lateral dimension 23 of the vehicle, so that, on the one hand, the lateral end 114 of the first central set 11 of luminous surfaces 111 is positioned at most 75 millimeters from the medial end 125 of the luminous surface 121, 122, 123 of the second lateral set 12 and that, on the other hand, the first central set 11 is configured to be actuated jointly with the second lateral set 12 in the form of a set of actuated luminous surfaces 111, 121, 122, 123 spaced at most 75 millimeters apart.

[0011] The lighting assembly according to the invention is thus subdivided into, on the one hand, a first set 11 of luminous surfaces 111 positioned at a central part of the front face 2 of the vehicle and primarily adapted for generating a position light signal, and, on the other hand, a second set 12 of luminous surfaces 121, 122, 123 positioned laterally on the front face 2 of the vehicle and adapted to participate both in the position light signal and in the signal of another function. The lighting assembly according to the invention thus integrates, in addition to the luminous surfaces intended for generating a position light signal, one or more luminous surfaces 121, 122, 123 positioned laterally on the front face of a vehicle and which also participate in generating a light signal other than that of the position lights.By using luminous surfaces 121, 122, 123, whose position on the front face 2 of the vehicle defines a lateral end 124 positioned within a maximum required distance from the overall lateral dimensions 23 of the vehicle, the lighting assembly according to the invention is then able to provide light distribution for a position light signal to a more centralized portion of the front face 2 of the vehicle, thus meeting regulatory requirements. Furthermore, by integrating into the lighting assembly for generating a position light signal one or more luminous surfaces that also contribute to generating another light signal, the lighting assembly according to the invention is able to meet, at least partially, the space constraints related to the multiplication of light sources or means of light production on the front face 2 of the vehicle.

[0012] According to an example relating to a variant of the construction of the lighting assembly according to the invention, the first central assembly 11 of luminous surfaces 111 is made up of at least one printed circuit board incorporating light-emitting diodes. According to this variant of the construction, the light source of the luminous surface 111 of the first central assembly 11 involves a device with a particularly small footprint, allowing it to be positioned in spaces or gaps with limited volume. Furthermore, the use of printed circuit boards incorporating light-emitting diodes allows for the distribution of light sources or light-producing means arranged in a chain, thus achieving continuous illumination of the surfaces 111 of the first central assembly 11.

[0013] According to an example relating to a preferred construction variant of the lighting assembly according to the invention, which can be combined with either of the variants detailed above, at least one luminous surface 122 of the second lateral assembly 12, actuated jointly with the first central assembly 11 of luminous surfaces 111, is dedicated to cornering lights. This construction variant makes it possible to benefit from the luminous surface 122 associated with a light-producing means, the actuating of which, outside the scope of the invention, is used to couple the low-beam headlights under certain vehicle operating conditions. These cornering lights are generally accessory and are triggered automatically based on various parameters such as vehicle speed, steering angle, and the operation of a turn signal, as analyzed by a computer.Since the light surfaces dedicated to the cornering lights 122 complement the light surfaces dedicated to the dipped headlights 121 or the main beam headlights 123, these light surfaces dedicated to the cornering lights 122 are therefore subjected to less stress than their counterparts dedicated to the dipped headlights 121 or the main beam headlights 123. Also, the use of the light surfaces dedicated to these cornering lights 122, at least as part of the second lateral assembly 12 of the lighting assembly according to the invention, makes it possible to benefit from the privileged position on the front 2 of the vehicle, of light surfaces which also participate in the generation of a light signal other than that of the position lights and have optimal availability to participate in the production of a position light signal.

[0014] According to an example relating to a variant construction of the lighting assembly according to the invention and capable of being combined with either of the variants detailed above, the lighting assembly also includes at least one device for modulating the light intensity of at least one dedicated luminous surface 121, 122, 123 of the second lateral assembly 12 with respect to the light intensity of the first central assembly 11 of luminous surfaces 111 operated jointly as part of the operation of the lighting system. Within the lighting system according to the invention, the luminous surfaces 121, 122, 123 of the second lateral assembly 12 are also intended to generate a light signal other than that of the position lights. For safety reasons, however, it is imperative that the luminous intensity of this other signal, which corresponds to the dipped headlights 121 and / or the cornering lights 122 and / or the main beam headlights 123 of the vehicle, be greater than a minimum value. Conversely, for a position light signal, the required luminous intensity must be lower to meet regulatory photometric requirements.Also, within the framework of this construction variant, the integration of the luminous surfaces 121, 122, 123 of the second lateral assembly 12 into the lighting assembly according to the invention is coupled to a device for modulating the luminous intensity of these luminous surfaces 121, 122, 123 so that this intensity is adapted to the type of light signal to which the luminous surfaces 121, 122, 123 of the second lateral assembly 12 are associated in their operation.Thus, when one of the luminous surfaces 121, 122, 123 of the second lateral assembly 12 is activated to emit a signal corresponding to the low beam headlights and / or cornering lights and / or high beam headlights, the modulation device activates the light-producing means of these luminous surfaces 121, 122, 123 to produce a luminous intensity higher than that produced when coupled with the luminous surfaces of the first medial assembly 11 to emit a position light signal. In a specific implementation example of this variant, the lighting assembly incorporates a common modulation device for the various light-producing means of the luminous surfaces 121, 122, 123 of the second lateral assembly 12.Alternatively, the lighting assembly incorporates several modulation devices so that each of them is respectively associated with one or more means of producing light from the luminous surfaces 121, 122, 123 of the second lateral assembly 12 participating in the emission of the same light signal which is other than that of the position lights.

[0015] According to an example relating to a variant construction of the lighting assembly according to the invention and capable of being combined with the variant detailed above, at least one light intensity modulation device incorporates a mechanism for modulating the electrical pulse width transmitted to the light-producing means of the luminous surfaces 111, 121, 122, 123. According to this variant construction, the modulation of the light intensity generated at the level of the various luminous surfaces 111, 121, 122, 123 of the lighting assembly is achieved while maintaining a constant electrical power transmitted to the light-producing means. The light intensity is modified by varying the frequency and / or duration of the electrical pulses transmitted to the light-producing means. Reducing the duration of the electrical signal for each pulse thus increases the flicker of the light-producing means, thereby reducing the intensity of the light produced at the corresponding luminous surfaces 111, 121, 122, 123 of the lighting system. Conversely, increasing the frequency and / or duration of the electrical signal for each pulse reduces the flicker of the light-producing means and increases the intensity of the light produced at the corresponding luminous surfaces 111, 121, 122, 123 of the lighting system.

[0016] According to an example relating to a variant construction of the lighting assembly according to the invention and capable of being combined with either of the variants detailed above, the support structure 21 comprises several housings respectively dedicated to the positioning of the different light-producing means for the luminous surfaces 111, 121, 122, 123 of the lighting assembly. Within the framework of the lighting assembly according to the invention, the support structure 21 contributes to the integration and positioning of the luminous surfaces 111 of the first central assembly 11 and the luminous surfaces 121, 122, 123 of the second lateral assembly 12 at the level of the front face 2 of the vehicle.According to an example relating to a first specific variant of this construction variant, a single support structure 21 positions all the light surfaces 111, 121, 122, 123 of the two assemblies, central 11 and lateral 12, in a position at least on one lateral half of the front face 2 of a vehicle. The support structure 21 is then arranged to be mounted on at least a portion corresponding to one lateral half of the front face 2 of a vehicle. This support structure 21 is thus common to several light-producing means associated with different light surfaces 111 of the first central assembly 11 and different light surfaces 121, 122, 123 of the second lateral assembly 12. This support structure 21 may also incorporate a housing adapted to receive a modulation device associated with one or more of the light-producing means held in position by the structure.According to another example relating to a second specific variant of this construction variant, the support structure 21 is divided into at least two independent structural portions 21a, 21b which position the various light surfaces 111, 121, 122, 123 of the lighting assembly at the level of at least one lateral half of the front face 2 of a vehicle. Within this specific construction variant, each of the different portions 21a, 21b is configured to position one or more respective light surfaces 111, 121, 122, 123. By way of example, a first portion 21a of the support structure 21 positions the light surfaces 111 of the first central assembly 11 and a second portion. 21b of the support structure 21 positions the various light surfaces 121, 122, 123 of the second lateral assembly 12. The different portions 21a, 21b of the support structure 21 are then detached from one another and adapted for independent installation on the vehicle. Each of these portions 21a, 21b of the support structure 21 is thus common to several light-producing means of the lighting system. Furthermore, each of the portions 21a, 21b of the support structure 21 is also capable of incorporating a housing adapted to receive a modulation device associated with one or more of the light-producing means held in position by the relevant portion 21a, 21b of the support structure 21.

[0017] According to an example relating to a construction variant of the lighting assembly according to the invention and capable of being combined with the variant detailed above, each housing for the light-producing means of the luminous surfaces 111, 121, 122, 123 includes a reflection mechanism and is associated with a protective glass. According to a specific construction example of this construction variant, the reflection mechanism involves a parabolic mirror arranged on the side of the housing opposite the protective glass with respect to the light-producing means.

[0018] The invention also relates to a vehicle equipped with at least one pair of lighting assemblies according to the invention, such that the lighting assemblies are mounted on the front face 2 of the vehicle, symmetrically on either side of the vehicle's median longitudinal vertical plane. This symmetrical arrangement of the lighting assemblies on the vehicle allows the emission of a visible position light signal over a large portion of the vehicle's front face.Each lighting assembly is positioned between a lateral end 124 located less than 400 millimeters from the overall lateral dimensions 23 of the vehicle and a medial end 125 close to the central part of the front face 2 of the vehicle. A significant portion of the front face 2 of the vehicle, particularly in the central part, is thus able to incorporate one or more luminous surfaces 111 adapted for emitting a position light signal and capable of being used to create an original lighting design or to highlight specific elements of the front face 2 of the vehicle. Preferably, the lighting assemblies mounted on the front face 2 of the vehicle are arranged to be actuated and operate together as part of the emission of a position light signal.

[0019] According to an example relating to a variant of the vehicle construction according to the invention and capable of being combined with the variant detailed above, the respective luminous surfaces 111 of the first central assemblies 11 of each Lighting assemblies converge on the front face 2 of the vehicle at the level of at least a portion of the grille 22 and / or near and / or at the level of the longitudinal median vertical plane of the vehicle. In this example of vehicle construction according to the invention, any part of the front face 2 of the vehicle is capable of carrying at least one luminous surface 111, 121, 122, 123 for emitting a vehicle position light signal while complying with regulatory constraints relating in particular to the positioning of a lateral end 124 located less than 400 millimeters from the overall lateral dimension 23 of the vehicle.

[0020] The invention also relates to a method of operating a lighting assembly according to the invention, characterized in that the method comprises: - a joint actuation step, on the one hand, of the first central set 11 of luminous surfaces 111 and, on the other hand, of at least one luminous surface 121, 122, 123 of the second lateral set 12, by modulation of the luminous intensity emitted by each of the actuated luminous surfaces 111, 121, 122, 123. The combined actuation of the various luminous surfaces 111, 121, 122, 123 of the lighting assembly of the invention thus enables the emission of a position light signal on the front 2 of the vehicle. Since the luminous surfaces 111 of the first central assembly 11 are solely intended for emitting a position light signal, the luminous intensity of the light-producing means is specifically calibrated for this signal when the light-producing means are amplified. Conversely, at least one luminous surface 121, 122, 123 of the second lateral assembly 12 is also intended for emitting a light signal other than a position light signal.Also, the actuation of this at least one luminous surface 121, 122, 123 of the second lateral assembly 12 within the framework of the operation of the lighting assembly of the invention is coupled to a modulation of its luminous intensity so that it is adapted to the luminous intensity required in the context of the emission of a light signal of position lights in particular when this photometric intensity differs from that of the light signal other than that of position lights in which the at least one luminous surface 121, 122, 123 of the second lateral assembly 12 participates.

[0021] According to an example relating to a variant of the implementation of the method according to the invention, once the type of at least one luminous surface 121, 122, 123 of the second lateral assembly 12 actuated jointly with the first central assembly 11 of luminous surfaces 111 and the normal operation of this at least one luminous surface 121, 122, 123 are identified, the step of modulating the light intensity emitted by each of the actuated luminous surfaces 111 includes in particular: - on the one hand, a step of maintaining the luminous intensity of the first central set 11 of luminous surfaces 111 above a minimum value and, - on the other hand, a step of substituting any extinction of at least one luminous surface 121, 122, 123 of the second set 12 by maintaining a luminous intensity equal to or greater than a non-zero minimum value. In this variant of the implementation of the method of the invention, maintaining the light intensity of the first central assembly 11 above a minimum value allows the emission of a light signal of position lights. Preferably, the modulation of the luminous intensity for this signal is also arranged to maintain this intensity below a maximum value in order to comply with the legal or regulatory provisions relating to the required luminous intensity of a position light signal. Furthermore, since at least one luminous surface 121, 122, 123 of the second lateral assembly 12 also participates in the emission of a low beam and / or cornering light and / or high beam signal, that is to say, a light signal whose luminous intensity is greater than that of a position light signal, the modulation of the luminous intensity of at least one luminous surface 121, 122, 123 of the second lateral assembly 12 then consists of adapting the luminous intensity to the type of light signal in which this second lateral assembly 12 participates.In this variant of the method according to the invention, this luminous intensity is thus alternately, on the one hand, increased when at least one luminous surface 121, 122, 123 of the second lateral assembly 12 is used to produce a light signal of dipped headlights and / or cornering lights and / or main beam headlights and, on the other hand, in the context of the operation of the lighting assembly of the invention, reduced to a non-zero value when at least one luminous surface 121, 122, 123 of the second lateral assembly 12 ceases to participate in the emission of a light signal of dipped headlights and / or cornering lights and / or main beam headlights. The luminous intensity of at least one luminous surface 121, 122, 123 of the second lateral assembly 12 is then zero only in the absence of participation of this at least one luminous surface 121, 122, 123 in the emission of any light signal.Thus, according to an example relating to a variant of the implementation of the method according to the invention and capable of being combined with the variant previously detailed, the luminous intensity of at least one luminous surface 121, 122, 123 of the second lateral assembly 12 is adjusted to an intensity value necessary for the emission of a low beam and / or cornering beam and / or high beam signal by this at least one luminous surface 121, 122, 123 such that this necessary intensity value is greater than the non-zero minimum value.

[0022] According to an example relating to a variant of the implementation of the method according to the invention and capable of being combined with one or the other of the variants previously detailed, the minimum value of the luminous intensity of the luminous surfaces 111, 121, 122, 123 actuated by the first central assembly 11 and the second lateral assembly 12 corresponds to the value of the luminous intensity required for a position light.Also, in the context of the operation of the lighting assembly of the invention according to this variant of the method, as soon as at least one luminous surface 121, 122, 123 of the second lateral assembly 12 ceases to participate in the emission of a light signal of dipped beam and / or cornering beam and / or main beam, the luminous intensity of this at least one luminous surface 121, 122, 123 is reduced to a non-zero value which, on the one hand, is less than that of a light signal of dipped beam and / or cornering beam and / or main beam and, on the other hand, is within the range of luminous intensity required for a light signal of position lights.

[0023] According to an example relating to an embodiment of the method according to the invention and capable of being combined with either of the previously detailed embodiments, the luminous intensity of the first central assembly 11 of luminous surfaces 111 is kept constant. According to this construction embodiment, within the framework of the operation of the lighting assembly of the invention, the luminous surfaces 111 of the first central assembly 11 being solely intended to produce a light signal of position lights, only one level of luminous intensity for such a signal is necessary, so that no variation in the intensity of the signal is expected.

[0024] Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, particularly with regard to the composition of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

A method of operation according to claim 10, characterized in that, once the type of at least one luminous surface (121, 122, 123) of the second lateral assembly (12) actuated jointly with the first central assembly (11) of luminous surfaces (111) and the normal operation of this at least one luminous surface (121, 122, 123) are identified, the step of modulating the luminous intensity emitted by each of the actuated luminous surfaces (111) includes in particular: - on the one hand, a step of maintaining the luminous intensity of the first central assembly (11) of luminous surfaces (111) above a minimum value and, - on the other hand, a step of substituting any extinction of at least one luminous surface (121, 122, 123) of the second assembly (12) by maintaining a luminous intensity equal to or greater than a non-zero minimum value.

12. A method of operation according to any one of claims 11, characterized in that the luminous intensity of at least one luminous surface (121, 122, 123) of the second lateral assembly (12) is adjusted to an intensity value necessary for the emission of a low beam and / or cornering light and / or high beam signal by this at least one luminous surface (121, 122, 123) such that this necessary intensity value is greater than the non-zero minimum value.

13. A method of operation according to claim 11, characterized in that the minimum value of the luminous intensity of the luminous surfaces (111, 121, 122, 123) actuated by the first assembly 15 central (11) and of the second lateral assembly (12) corresponds to the value of the luminous intensity required for a position light.

14. A method of operation according to any one of claims 10 to 13, characterized in that the luminous intensity of the first central set (11) of luminous surfaces (111) is kept constant.
