Description

[0001] The invention relates to the field of lighting modules for interior equipment of motor vehicles, in particular lighting modules with a light guide. The invention is particularly, but not exclusively, suitable for displaying light patterns on interior equipment for motor vehicles.

[0002] Currently, light patterns are often displayed in motor vehicle interiors in order to convey information, for aesthetic customization purposes or to create ambience.

[0003] It is also preferred to display such patterns at high resolution.

[0004] For this purpose, it is known to use a screen, such as an LCD screen.

[0005] However, this technology is not only expensive but also sensitive to environmental conditions such as temperature, humidity or UV radiation.

[0006] Furthermore, it is preferred to have a flexible lighting module in order to facilitate its integration into any type of equipment. This is particularly the case in motor vehicle interiors, where the interior equipment has non-planar surfaces.

[0007] Furthermore, there are significant space limitations in the interior of a motor vehicle and it is important to provide a compact lighting module.

[0008] Finally, the above-mentioned solution has the disadvantage of high energy consumption, wherein the energy consumption is greater the larger the surface area of ​​the device in which the lighting module is to be integrated.

[0009] Therefore, there is a need for an interior device for a motor vehicle, which interior device comprises a lighting module adapted to display a precise light pattern and which is robust, inexpensive, energy efficient, compact and easy to integrate.

[0010] The present invention improves this situation.

[0011] To this end, a first aspect of the invention relates to an interior device for a motor vehicle, the device comprising an outer surface on which a light module is arranged, the light module comprising:

[0012] an assembly of at least one flexible guide plate, each flexible guide plate in the assembly being adapted to receive light via at least one edge of the flexible guide plate and to reflect the light in a direction substantially perpendicular to a surface of the flexible guide plate according to at least one pattern etched in the flexible guide plate;

[0013] at least one light injection element adapted to receive light and distribute the light in the assembly of at least one flexible guide plate;

[0014] At least one light source is adapted to inject light into the at least one light injection element.

[0015] The use of a flexible guide plate makes it easier to integrate the lighting module into an interior device for a motor vehicle and also compact, since the lighting module can have a small thickness. In addition, large surface areas can be illuminated while limiting the number of light sources used.

[0016] According to an embodiment, the internal device may further include a touch-sensitive layer adapted to receive a touch input from a user, and the touch-sensitive layer may be located between the outer surface of the device and the light emitting module, or below the outer surface of the device.

[0017] Thus, the lighting module may be coupled with the touch sensitive layer to receive touch input from a vehicle user, thereby optimizing the use of confined space within a motor vehicle interior.

[0018] Additionally, the touch sensitive layer may be a capacitive layer.

[0019] This capacitor layer has good impact resistance.

[0020] According to an embodiment, the interior device may further comprise a control element adapted to control the at least one light source.

[0021] This makes it possible to manage the light source and thus change the pattern displayed by the lighting module. Thus, lighting animations or dynamic information can be displayed.

[0022] Additionally, the control element may be adapted to receive touch input data from the touch sensitive layer and may be configured to control the at least one light source depending on the touch input data.

[0023] The touch-sensitive layer is thus used to manage the display of the pattern of the lighting module, which makes it possible to provide the user with luminous feedback regarding his touch input.

[0024] In addition, the light emitting module may be adapted to display at least one symbol in a given area of ​​the light emitting module based on a pattern of each flexible guide plate in the component, and a touch-sensitive area of ​​the touch-sensitive layer opposite to the given area of ​​the light emitting module may be adapted to receive touch input to generate touch input data according to the touch-sensitive area.

[0025] This makes it easier for users to ensure that their touch input is accurate because illuminated feedback is provided in the touch-sensitive area where the touch input occurs.

[0026] In addition, the light-emitting module can be adapted to display at least a first symbol in a first given area of ​​the light-emitting module and at least a second symbol in a second given area of ​​the light-emitting module based on the pattern of each flexible guide plate in the component, and the first touch-sensitive area of ​​the touch-sensitive layer can be opposite to the first given area of ​​the light-emitting module, and the second touch-sensitive area of ​​the touch-sensitive layer can be opposite to the second given area of ​​the light-emitting module, first touch input data can be generated by the touch-sensitive layer when receiving a first touch input in the first touch-sensitive area, and second touch input data can be generated by the touch-sensitive layer when receiving a second touch input in the second touch-sensitive area.

[0027] This means that the user can enter several different touch inputs via the same device, allowing for more complex functionality.

[0028] According to an embodiment, the light emitting module may include a flexible guide plate, a light injection element and a light source, the light source may be adapted to project light within a first wavelength range and within a second wavelength range different from the first range, and the control element is adapted to control the light source to project light within the first range or within the second range.

[0029] Hence, the device is adapted to be dynamically controlled to vary the colour of the projected pattern.

[0030] Furthermore, the control element may be adapted to control the light source to project light within the first range or within the second range according to the animation command.

[0031] Therefore, a lighting animation or dynamic information for an atmosphere can be displayed.

[0032] Additionally or alternatively, the control element may be adapted to control the light source to project light within the first range or within the second range depending on the touch input data.

[0033] Thus, the color of the pattern depends on the user's touch input, which enriches the allowed interaction with the user.

[0034] According to the first embodiment or the second embodiment, the light emitting module may include a single flexible guide plate.

[0035] Thus, simple, inexpensive lighting modules can be used while displaying light patterns on large and potentially non-planar surfaces.

[0036] Alternatively, according to the second embodiment or according to the third embodiment or the fourth embodiment, the light-emitting module may include a first injection element and a second injection element, the at least one source may be adapted to selectively inject light into the first injection element and the second injection element, and the assembly of the first light injection element and at least one flexible guide plate may be arranged so as to project light according to a first pattern, and wherein the assembly of the second light injection element and at least one flexible guide plate is arranged so as to project light according to a second pattern.

[0037] Thus, the first injection element and the second injection element can be used separately, which allows animations to be achieved by color variations or spatial variations of the light emitted by the component.

[0038] Additionally, the lighting module of the interior device may include a first light source adapted to inject light into the first light injection element and a second light source adapted to inject light into the second light injection element.

[0039] Thus, control of dynamic display is made possible by managing sources enabled independently of each other.

[0040] Further, additionally, the first light source may be adapted to generate light in a first wavelength range and the second light source may be adapted to generate light in a second wavelength range different from the first range.

[0041] This makes it possible to dynamically change the color of the displayed pattern.

[0042] According to a second embodiment, the first injection element can be arranged so as to inject light into a first segment of an edge of a guide plate of the injection component, and the second injection element can be arranged so as to inject light into a second segment of an edge of a flexible guide plate, a first portion of the flexible guide plate positioned opposite to the first segment of the edge is etched according to a first pattern, and a second portion of the flexible guide plate positioned opposite to the second segment of the edge is etched according to a second pattern.

[0043] This makes it possible to produce several patterns at different spatial positions via a single flexible guide sheet, which limits the costs and space requirements associated with the light emitting module.

[0044] Alternatively, according to the third and fourth embodiments, the component may include at least a first flexible guide plate and a second flexible guide plate, a first pattern is etched in the first flexible guide plate, and a second pattern is etched in the second flexible guide plate, the first injection element is arranged so as to inject light into an edge of the first flexible guide plate, and the second injection element is arranged so as to inject light into an edge of the second flexible guide plate.

[0045] This makes it possible to create complex variations of patterns and / or to provide light-emitting modules covering a large illuminated surface area.

[0046] In addition, according to the third embodiment, the first guide plate and the second guide plate may be overlapped in the light emitting module so as to project the first pattern and the second pattern in a common area of ​​the light emitting module.

[0047] This makes it possible to change the pattern projected in the common area. Animation can be produced by dynamically changing the pattern of the common area or changing its color.

[0048] Furthermore, because the flexible guide plates are thin, they can be stacked without taking up significant space, which is particularly advantageous in constrained environments such as the interior of a motor vehicle.

[0049] Alternatively, according to a fourth embodiment of the present invention, the first guide plate and the second guide plate may be placed adjacent to each other in such a manner that the first pattern and the second pattern are projected at different positions.

[0050] This makes it possible to cover large emitting surface areas (in particular greater than 100 cm2) while allowing integration on irregular and complex surfaces.

[0051] In addition, the light-emitting module of the internal device may include more than two flexible guide plates, which are placed adjacent to each other in such a way as to form a matrix of flexible guide plates, each flexible guide plate being associated with a light injection element adapted to inject light into the edge of the flexible guide plate, and each flexible guide plate having at least one pattern etched in the plate.

[0052] This makes it possible to create complex light animations through spatial variations of the projected light, while allowing easy integration into devices with complex surfaces.

[0053] Additionally, in the fourth embodiment, the flexible guide plates in the assembly may have the same square shape or rectangular shape.

[0054] Thus, the production of the lighting module is simplified and the associated costs are reduced.

[0055] Furthermore, in the fourth embodiment, the size of the shape of the guide plate may be between 3 cm and 25 cm, in particular between 3 cm and 5 cm.

[0056] The dimensions of the matrix elements as flexible guides are therefore small, which makes it possible to produce lighting modules with a large number of flexible guides. This allows to display many patterns and thus create complex light animations.

[0057] Furthermore, according to the second, third or fourth embodiment, the control element may be adapted to control the at least one source to selectively project light according to the first pattern and according to the second pattern.

[0058] Thus, a single element is able to control the selective injection of light into various light injection elements of a lighting module, which improves the synchronization of the display of light patterns with respect to each other.

[0059] Furthermore, the control element may be adapted to dynamically control the at least one source in such a way that a light animation comprising at least the first pattern and the second pattern is generated.

[0060] This makes it easier to create light animations from patterns.

[0061] According to an embodiment of the invention, the interior device may be a dashboard of a motor vehicle.

[0062] Thus, it is possible to display information or create a luminous atmosphere for the front passengers of the vehicle. It is particularly important to disseminate information to the driver and even allow interaction with the driver. Furthermore, the dashboard comprises a non-flat surface and therefore the use of a luminous module with a flexible guide plate is particularly advantageous.

[0063] Additionally, the instrument panel may include an inflatable safety device beneath an outer surface of the instrument panel.

[0064] Since the lighting module comprises a flexible guide plate, the lighting module is easily deformed or torn, which allows the inflatable safety device to deploy in the event of a collision. Thus, both lighting / signaling and safety functions can be integrated into the same device.

[0065] Alternatively, the interior equipment may be a motor vehicle seat, a motor vehicle roof or a motor vehicle rear shelf.

[0066] The devices may all have non-planar surfaces and / or impose significant compactness constraints.

[0067] According to an embodiment of the invention, each flexible guide plate in the assembly may have a thickness between 0.2 mm and 1 mm.

[0068] Such a thickness allows the flexible guide plate to be highly flexible and facilitates its integration in particular on a curved support.

[0069] According to an embodiment of the present invention, at least one flexible guide plate in the assembly may be made of a transparent material.

[0070] This increases the integration possibilities of the light emitting module as well as its aesthetic appearance. Note that at least one of the flexible guide plates may be translucent or opaque.

[0071] In addition, each flexible guide plate in the assembly may include a polycarbonate (PC), polymethyl methacrylate (PMMA), thermoplastic polyurethane (TUP), or polyethylene terephthalate (PET) film.

[0072] This material makes it possible to produce transparent and flexible guide plates.

[0073] According to an embodiment of the present invention, each flexible guide plate may include a film including a microstructure, in which each of the first pattern and the second pattern is etched by ultraviolet printing the microstructure of the film.

[0074] This microstructure enables the creation of high-resolution patterns while maintaining a high level of transparency of the flexible guide plate.

[0075] Additionally, for each flexible guide plate, the surface density of the microstructures may decrease with distance from the edge of the guide plate, into which the light is injected.

[0076] The uniformity of the pattern projected by the flexible guide plate is thus improved.

[0077] According to an embodiment of the present invention, each injection element may include a plurality of injection guides, each injection guide being adapted to receive light from one end of the guide and guide the light to a given longitudinal position on the injection element, the longitudinal positions of the injection guides being different so as to distribute the light longitudinally in the injection element.

[0078] This allows the light to be evenly distributed in the edge of the flexible guide plate, which improves the quality of the projection of the first and second patterns.

[0079] Other features and advantages of the present invention will become apparent by reviewing the following detailed description and the accompanying drawings, in which:

[0080] [ Figure 1 ] depicts a lighting module for interior equipment of a motor vehicle according to a first embodiment of the invention;

[0081] [ Figure 2 ] depicts an injection element of a light emitting module according to an embodiment of the present invention;

[0082] [ Figure 3 ] depicts a lighting module for interior equipment of a motor vehicle according to a second embodiment of the invention;

[0083] [ Figure 4 ] depicts a lighting module for interior equipment of a motor vehicle according to a third embodiment of the invention;

[0084] [ Figure 5] depicts a lighting module for interior equipment of a motor vehicle according to a fourth embodiment of the invention;

[0085] [ Figure 6 ] depicts an apparatus for a motor vehicle according to an embodiment of the invention.

[0086] The present description focuses on features that distinguish the interior device or lighting module from interior devices or lighting modules known in the prior art.

[0087] [ Figure 1 ] shows a lighting module 100 for a motor vehicle according to a first embodiment of the present invention.

[0088] The light emitting module 100 comprises a flexible guide plate 110 adapted to receive light via an edge 114 and to reflect the light in a direction Z substantially perpendicular to the surface of the flexible guide plate, the flexible guide plate thus being arranged in a direction [ Figure 1 ] extends in plane XY in .

[0089] A guide plate is understood to mean a light-guiding element, one of the dimensions of which is much smaller in space than the other two dimensions, for example, one or more orders of magnitude smaller. Figure 1 ] As shown in FIG. 1 , in this case, the guide plate is a flexible guide plate whose thickness along the Z axis is at least two orders of magnitude smaller than its dimension in the plane XY in which the flexible guide plate 110 extends.

[0090] The flexible guide plate 110 may include a flexible membrane 111 at its core, the flexible membrane including at least one edge 114 adapted to guide light in a general direction X, and including a set of microstructures 113 adapted to reflect light guided in the flexible membrane 111 to the outside of the flexible guide plate 110, in particular in one or more directions substantially along the axis Z.

[0091] The flexible film 111 may be a substrate film made of polycarbonate (PC), polymethyl methacrylate (PMMA), thermoplastic polyurethane (TUP) or polyethylene terephthalate (PET). The flexible film 111 may have a thickness, i.e. a dimension along the axis Z, between 12 microns and 1000 microns. More specifically, the thickness of the flexible film 111 may be between 50 microns and 1000 microns, for example between 200 microns and 500 microns. Alternatively, it is a flexible guide plate 110 having a thickness between 200 microns and 1000 microns.

[0092] The above materials, in combination with the low thickness as described above, make it possible to obtain a flexible membrane 111. Other materials can be considered for the composition of the flexible membrane 111. However, it is preferred according to the invention to provide a deformable transparent material.

[0093] A thin coating of microstructures 113 may be applied to one of the faces of the flexible membrane 111 or integrated in the flexible membrane 111. The microstructure coating 113 may in particular have a thickness along the axis Z of less than 20 micrometers.

[0094] Such microstructures 113 may generally take the form of bumps on which light is reflected in a direction substantially along the axis Z. Such microstructures 113 may be adapted to pattern the light leaving the flexible membrane 111. To this end, the microstructures 113 may be etched by UV printing according to the desired pattern.

[0095] The microstructures 113 are structures or irregularities of the flexible film with a size less than a few micrometers. Therefore, the microstructures also cover the nanostructures. Microstructures 113 of such size make it possible to ensure a high transparency of the flexible film 111. In particular, a transparency of about 97% can be obtained in practice by using the microstructures 113. Alternatively, the flexible guide plate can be translucent or opaque.

[0096] Advantageously, the microstructures 113 may be distributed along the axis X so that the linear density of the microstructures 113 is proportional to the distance from the edge 114 via which the light injected by the injection element 120 is received. In other words, the farther the microstructures 113 are from the edge 114, the denser they are grouped together. Such a distribution advantageously makes it possible to ensure a uniform distribution of the luminous intensity of the pattern emitted by the flexible guide plate 110 along the axis X.

[0097] The flexible guide plate 110 may further comprise one or two optional protective layers 112.1 and 112.2 making it possible to mechanically protect the flexible film 111. Furthermore, at least one of the protective layers 112.1 and 112.2 may comprise an anti-UV treatment, making it possible to protect the flexible film from UV rays once the microstructures 113 have been etched. Without such UV protection, the pattern projected by the flexible guide plate 110 may deteriorate over time, in particular when exposed to sunlight.

[0098] The flexible film 111 and the protective layers 112.1 and 112.2 are in [ Figure 1 ] are shown as spaced apart, this is purely for illustrative purposes. However, it will be understood that the protective layers 112.1 and 112.2 can be attached to the flexible film, in particular by lamination.

[0099] Since the guide plate 110 is flexible, it is not necessarily comprised in a plane, but can be bent, depending on where it is placed and the mechanical constraints imposed on it.

[0100] [ Figure 1] The light module 100 shown in FIG. 1 further includes a light injection element 120 (also referred to as a light strip), because the light injection element extends longitudinally in a direction Y and is adapted to extend in a direction perpendicular to its longitudinal direction (e.g., in a direction perpendicular to its longitudinal direction). Figure 1 ] When arranged in the manner shown, light is injected along the axis X).

[0101] The light injection element 120 is Figure 1 ] has a rectangular or square cross-section. However, the light injection element 120 may have a circular, elliptical or polygonal cross-section.

[0102] Thus, the light injection element 120 comprises an output surface 122 extending in a longitudinal direction and adapted to inject light in a direction substantially perpendicular to the output surface 122. The light injection element 120 further comprises an input surface 121 adapted to receive light from the light source 130 at one end of the light injection element 120, and the light injection element 120 is adapted to guide the light longitudinally along the axis Y, thereby distributing the light on the output surface 122. Figure 2 ]The distribution of light by the output surface 122 will be more clearly understood in the description of FIG.

[0103] There is no limitation on the light source 130. The light source 130 may be adapted to produce light within a range of wavelengths. Such a range may be centered around visible colors so as to produce colored light, such as blue, red, or green. Alternatively, the light source 130 may emit light across the entire wavelength range visible to the human eye in such a way that white light is produced. Laser-type light sources 130 may produce a very narrow range of wavelengths.

[0104] The light source 130 may be adapted to generate light in at least two different wavelength ranges, for example corresponding to two different colors. The light source may be, for example, a light emitting source of the LED type, which has the advantages of, for example, small size, low energy consumption and not heating up very much, thereby generating light of two different colors, adapted to be controlled by a control element (not shown). The light source may in particular be an RGB type diode adapted to generate red light, green light and blue light. Therefore, the light emitting module according to the first embodiment may include a flexible guide plate 110, an injection element 120, and a light source 130 adapted to generate light in at least two different wavelength ranges.

[0105] The light source 130 may be controlled by a control element (not shown but described below) to vary the projected color and thereby create a light animation. Alternatively, the color may be dynamically controlled based on touch input data received by the control element, such as from [ Figure 6 ] can be understood more clearly in the description of .

[0106] Alternatively, the light source 130 is not arranged directly opposite the input surface 121 of the injection element 120, but the lighting module 100 further comprises an optical fiber placed between the light source 130 and the injection element 120, which makes it possible to move the source 130 away from the assembly formed by the injection element 120 and the flexible guide plate 110.

[0107] [ Figure 2 ] shows an injection element 120 of a light emitting module according to an embodiment of the present invention.

[0108] The injection element 120 may include a plurality of injection guides 123 adapted to receive light from a source 130 via an input surface 121 and guide the light to longitudinal positions on an output surface 122, wherein the longitudinal positions of the light guides are different in such a manner that the light is distributed to at least several longitudinal positions on the output surface 122.

[0109] This makes it possible to inject light at different longitudinal positions on the edge 114 along the axis Y. Each longitudinal position on the edge 114 may correspond to a guide line of the flexible membrane 111 adapted to guide light along such guide line along the axis X.

[0110] This combination of flexible guide plate 110 , injection element 120 and source 130 thus makes it possible to project light in direction Z via a flexible, transparent, translucent or opaque surface with good surface homogeneity and according to a given pattern.

[0111] In practice, such a lighting module may make it possible to emit a pattern having a brightness between 100 and 1000 candela per square meter, wherein the light extraction efficiency may range between 25% and 80%.

[0112] Details regarding the structure and arrangement of these elements 110 , 120 , and 130 are further described in the international patent application published under number WO 2011130715 A2.

[0113] The lighting module for interior equipment of a vehicle according to the present invention comprises:

[0114] - At least one guide plate (such as [ Figure 1 ] an assembly of a flexible guide plate 110) as shown in FIG. 1 , the assembly being adapted to reflect light according to at least one pattern;

[0115] - at least one light injection element, such as a reference Figure 1 and Figure 2 The described injection element 120; and

[0116] - at least one light source (such as reference [ Figure 1] the light source 130 described, the at least one light source being adapted to inject light into the at least one injection element.

[0117] "Pattern" refers to any predefined spatial distribution of the luminous intensity emitted by the light-emitting module. In particular, reference is made here to a two-dimensional pattern or a one-dimensional pattern. Thus, the pattern may comprise a two-dimensional shape or symbol obtained by contrast between the luminous intensity at different positions in the plane XY of the flexible guide plate 110. The pattern may also comprise several shapes or symbols. Alternatively, the pattern covers a predefined or intentional spatial distribution of the luminous intensity that does not result in the appearance of any overall shape, such as a distribution that results in a cloud of luminous points. In the context of the present invention, the pattern is formed by injecting light into an injection element that is arranged relative to the flexible guide plate in such a way that a pattern is formed on the flexible guide plate. The flexible guide plate is thus adapted to project light according to at least one pattern, and the pattern may correspond to at least one shape or symbol. When the flexible guide plate is combined with several injection elements, the flexible guide plate may also project light according to at least two patterns.

[0118] In a first embodiment, the lighting module comprises a single source, a single injection element and a single flexible guide plate adapted to form a pattern.

[0119] In the following second, third and fourth embodiments, the light module comprises at least two injection elements similar to the above-mentioned injection element 120. These embodiments may vary according to the number of elements included in the light module and their corresponding arrangement. However, the description and definition of the light source, injection element and flexible guide plate given above apply to all embodiments.

[0120] [ Figure 3 ] shows a light emitting module 300 according to a second embodiment of the present invention.

[0121] In a second embodiment, several injection elements are arranged such that light is injected into the same flexible guide plate, the flexible guide plate comprising several patterns.

[0122] In particular, in [ Figure 3 ] in the example, the first injection element 320 . 1 and the second injection element 320 . 2 are arranged so as to inject light into the edge 314 of the flexible guide plate 310 .

[0123] The first injection element 320.1 and the second injection element 320.2 may be similar to the reference Figure 1 and Figure 2 Similarly, the flexible guide plate 310 may correspond to the flexible guide plate 110 described above.

[0124] like[ Figure 3] As shown in FIG. 1 , the first injection element 320.1 and the second injection element 320.2 are arranged so as to inject light into the edge 314 at different longitudinal positions along the axis Y.

[0125] Note that since the guide plate 310 is flexible, the guide plate may not be flat but may be curved. Figure 3 ] shows the light emitting module 300 when the guide plate is flat (eg placed on a flat rigid support).

[0126] Thus, the first injection element 320.1 is adapted to inject light into the edge 314 which is then guided by the flexible guide plate 310 into the first part 315.1 of the flexible guide plate 310. The second injection element 320.2 is adapted to inject light into the edge 314 which is then guided into the second part 315.2 of the flexible guide plate 310.

[0127] For this purpose, the first source 330.1 is arranged opposite the input surface of the first injection element 320.1 in such a way that the light propagates within the first injection element 320.1 and thus towards the first portion 315.1 of the flexible guide plate 310. The second source 330.2 is arranged opposite the input surface of the second injection element 320.2 in such a way that the light propagates within the second injection element 320.2 and thus towards the second portion 315.2 of the flexible guide plate 310.

[0128] Alternatively, a single source may be provided and the light emitting module 300 comprises a first optical fiber adapted to transmit light from the single source to an input surface of the first injection element 320.1 and a second optical fiber adapted to transmit light from the single source to an input surface of the second injection element 320.2.

[0129] The first source 330.1 and the second source 330.2 or a single source can selectively inject into the first injection element 320.1 and / or into the second injection element 320.2. This selective injection can be controlled by a control element (CTRL) 340 connected to the two sources 330.1 and 330.2 or controlling the power supply to the two sources 330.1 and 330.2.

[0130] A first pattern 316.1 is etched in the first portion 315.1, and a second pattern 316.2 is etched in the second portion 315.2. Selective injection of light into the first injection element 320.1 and / or the second injection element 320.2 enables the first pattern to be projected, the second pattern to be projected, neither of these patterns to be projected, or both patterns to be projected simultaneously, thereby enabling the generation of animations from at least the first pattern and the second pattern, or display of dynamic luminous information, by dynamic control. Alternatively, the selective injection of light may be dynamically controlled based on touch input data received by the control element 340, such as from [ Figure 6 ] can be understood more clearly in the description of .

[0131] exist[ Figure 3 ], the first pattern 316.1 and the second pattern 316.2 each correspond to a symbol, which symbols are different. However, consistent with the definition of "pattern" given above, these patterns can be any intentional or predetermined spatial distribution of luminous intensity. In addition, in the case where the patterns are shapes or symbols, the first pattern 316.1 and the second pattern 316.2 can have the same shape. The animation is then achieved by the spatial movement of the pattern from the first part 315.1 to the second part 315.2, or vice versa. In addition, when the sources 330.1 and 330.2 produce light of different colors, the color projected for each pattern respectively can vary.

[0132] [ Figure 3 ] shows an example with two patterns and two injection elements. However, the first embodiment also covers a light emitting module having a flexible guide plate with three or more parts and having at least three injection elements, each part comprising an etched pattern, each injection element being placed opposite one of the parts.

[0133] A dedicated source for each injection element may be provided for this purpose, or a single source with several optical fibers may be provided for this purpose.

[0134] [ Figure 4 ] shows a light emitting module 400 according to a second embodiment of the present invention.

[0135] In a second embodiment of the present invention, the light emitting module 400 comprises at least a first flexible guide plate 410.1 and a second flexible guide plate 410.2, which are stacked, meaning that at least a portion of the first flexible guide plate 410.1 in the plane XY overlaps with at least a portion of the second flexible guide plate 410.2 in a common area corresponding to a set of positions in the plane XY.

[0136] Preferably, the first flexible guiding plate 410.1 and the second flexible guiding plate 410.2 have the same dimensions in the plane XY and completely overlap.

[0137] Note that since the guide plate is flexible, the guide plate may not be flat but may be curved. Therefore, [ Figure 4 ] shows the light emitting module 400 when the guide plate is flat (eg, stacked on a flat support).

[0138] Such superposition is particularly advantageous since, as mentioned above, the flexible guide plate is preferably transparent.

[0139] Hence, the first flexible guide plate 410.1 and the second flexible guide plate 410.2 are adapted to project the first pattern 416.1 and the second pattern 416.2, respectively, in a common area.

[0140] The first injection element 420.1 is arranged to inject light into an edge of the first flexible guide plate 410.1 and the second injection element 420.2 is adapted and arranged to inject light into an edge of the second guide plate 410.2.

[0141] For this purpose, the first source 430.1 is arranged opposite the input surface of the first injection element 420.1 in such a way that the light propagates within the first injection element 420.1 and thus towards the first flexible guide plate 410.1. The second source 430.2 is arranged opposite the input surface of the second injection element 420.2 in such a way that the light propagates within the second injection element 420.2 and thus towards the second flexible guide plate 410.2.

[0142] Alternatively, a single source may be provided and the lighting module comprises a first optical fiber adapted to transmit light from the single source to an input surface of the first injection element 420.1 and a second optical fiber adapted to transmit light from the single source to an input surface of the second injection element 420.2.

[0143] The first source 430.1 and the second source 430.2 or a single source may selectively inject into the first injection element 420.1 and / or into the second injection element 420.2. Such selective injection may be controlled by a control element 440 connected to or controlling the power supply to the two sources 430.1 and 430.2.

[0144] A first pattern 416.1 is etched in the first flexible guide plate 410.1, and a second pattern 416.2 is etched in the second flexible guide plate 410.2. Selective injection of light into the first injection element 420.1 and / or the second injection element 420.2 thus enables the first pattern to be projected, the second pattern to be projected, neither of these patterns to be projected, or both patterns to be projected simultaneously, thereby enabling animation to be generated from at least the first pattern and the second pattern by dynamic control. Alternatively, the selective injection of light can be dynamically controlled based on touch input data received by the control element 440, such as from [ Figure 6 ] can be understood more clearly in the description of .

[0145] exist[ Figure 4 ], for illustrative purposes, the first pattern 416.1 and the second pattern 416.2 have different symbols and are similar to [ Figure 3 ] are the same as the patterns 316.1 and 316.2. However, consistent with the definition of pattern given above, these patterns can be any intentional or predetermined spatial distribution of luminous intensity. In addition, in the case where the pattern is a shape or symbol, the first pattern 416.1 and the second pattern 416.2 can have the same symbol but different colors. Specifically, when the sources 430.1 and 430.2 generate light of different colors, the color projected for each pattern can vary.

[0146] [ Figure 4 ] shows an example with two patterns, two injection elements and two flexible guide plates. However, the second embodiment also covers a lighting module with at least three flexible guide plates, with at least three injection elements, each injection element being placed opposite one of the flexible guide plates. A dedicated source for each injection element can be provided for this purpose, or a single source with several optical fibers can be provided for this purpose.

[0147] At least one of the flexible guide plates may be transparent. Alternatively, according to the second embodiment, the flexible guide plate located below the light emitting module 400 (in other words, the first flexible guide plate 410.1) may be opaque or translucent. Conversely, the second flexible guide plate 410.2 is transparent or translucent so as to allow at least a portion of the light emitted by the first flexible guide plate 410.2 to pass through. The second flexible guide plate 410.2 may further include a textured material so as to improve the aesthetic appearance of the light emitting module and / or to match its material with the material of the internal device in which the light emitting module is integrated. Such a textured material may also be used for the flexible guide plates of the light emitting modules according to the first, second and fourth embodiments. A textured material refers to any material having a predefined texture, which predefined texture relates to, for example, a surface treatment of the flexible guide plate. The textured material may include particles, ridges or cracks or any other texture elements.

[0148] [ Figure 5 ] shows a light emitting module 500 according to a fourth embodiment of the present invention.

[0149] In a fourth embodiment of the present invention, the light emitting module 500 comprises at least a first flexible guide plate 510.1 and a second flexible guide plate 510.2, which are placed adjacent to each other and are therefore adapted to project light from different positions in a plane XY in which the flexible guide plates mainly extend.

[0150] Note that since the guide plate is flexible, the guide plate may not be flat but may be curved. Therefore, [ Figure 5 ] shows the light emitting module 500 when the flexible guide plate is flat (eg placed on a flat rigid support).

[0151] Thus, the first flexible guide plate 510.1 is adapted to project a first pattern (not shown) at a first position on the plane XY, and the second flexible guide plate 510.2 is adapted to project a second pattern 516.2 at a second position on the plane XY, the first position and the second position being different, for example adjacent to each other. Each of the projected patterns may comprise a symbol or a portion of a symbol. When the pattern of a flexible guide plate comprises a portion of a symbol, this portion may be complementary to another portion of the symbol formed by the pattern of another flexible guide plate, or complementary to another portion of the symbol formed by the pattern of the other flexible guide plate.

[0152] The first injection element 520.1 is arranged to inject light into an edge of the first flexible guide plate 510.1 and the second injection element 520.2 is arranged to inject light into an edge of the second guide plate 510.2.

[0153] The relative arrangement of each injection element with respect to the flexible guide plate is in accordance with the explanations set out above and for [ Figure 5 ]The fourth embodiment of the present invention will not be described in detail.

[0154] The first source 530.1 is arranged opposite to the input surface of the first injection element 520.1 in such a way that the light propagates inside the first injection element 520.1 and thus towards the first flexible guide plate 510.1. The second source 530.2 is arranged opposite to the input surface of the second injection element 520.2 in such a way that the light propagates inside the second injection element 520.2 and thus towards the second flexible guide plate 510.2.

[0155] Alternatively, a single source may be provided and the lighting module 500 comprises a first optical fiber adapted to transmit light from the single source to an input surface of the first injection element 520.1 and a second optical fiber adapted to transmit light from the single source to an input surface of the second injection element 520.2.

[0156] The first source 530.1 and the second source 530.2 or a single source may selectively inject light into the first injection element 520.1 and / or the second injection element 520.2. Such selective injection may be controlled by a control element 540 connected to the two sources 530.1 and 530.2 or controlling the power supply to the two sources 530.1 and 530.2. Alternatively, the selective injection of light may be dynamically controlled based on touch input data received by the control element 540, such as from [ Figure 6 ] can be understood more clearly in the description of .

[0157] A first pattern is etched in the first flexible guide plate 510.1, and a second pattern is etched in the second flexible guide plate 510.2. Selective injection of light into the first injection element 520.1 and / or the second injection element 520.2 thus makes it possible to project the first pattern, project the second pattern, project neither of these patterns, or project both patterns simultaneously, thereby making it possible to generate an animation from at least the first pattern and the second pattern by dynamic control.

[0158] exist[ Figure 5 ], for illustrative purposes only, a light emitting module 500 including twelve flexible guide plates arranged in a matrix with three rows and four columns, twelve injection elements and twelve light sources has been shown.

[0159] In the third embodiment, there is no limit to the number of flexible guide plates. Therefore, the third embodiment is applicable to N flexible guide plates, N correspondingly associated injection elements, and N light sources or a single source connected to N injection elements by N optical fibers, where N is any integer greater than or equal to 2.

[0160] There is also no restriction on the arrangement of the flexible guide plates relative to each other. When they are positioned in a matrix, there is no restriction on the number of rows or columns.

[0161] The first pattern and the second pattern may have different shapes and may be, for example, [ Figure 3] are the same as the patterns 316.1 and 316.2. However, consistent with the definition of "pattern" given above, these patterns can be any intentional or predetermined spatial distribution of luminous intensity. In addition, in the case where the patterns are shapes or symbols, the first pattern and the second pattern can have the same symbol but different colors. Specifically, when sources 530.1 and 530.2 generate light of different colors, the color projected for each pattern can vary.

[0162] Furthermore, as explained above, the patterns may comprise symbol portions which are complementary to one another in such a way that one or more symbols are formed on several flexible guide plates of the matrix.

[0163] The flexible guide plates may be connected to each other by a support matrix structure, which itself may be flexible.Alternatively, each flexible guide plate may be connected to the surrounding flexible guide plate by fastening means, by adhesive bonding, clamping, clipping, or any other method.

[0164] The group of light sources can be controlled by a control element 540 via a group of wires, each wire connecting the control element 540 to a light source. The wires can be carried by a structure 550, making it possible to centralize and route the wires to the control element, thereby reducing bulk and also allowing shielding of the wires.

[0165] There is no restriction on the dimensions of the flexible guide plates in the plane XY. For example, each flexible guide plate may be rectangular or square in shape, with at least one dimension between 2 cm and 10 cm. For example, the flexible guide plates are square or rectangular, with:

[0166] - a size between 2 cm and 10 cm, for example between 2 cm and 5 cm, for example equal to 5 cm; and

[0167] - Another dimension between 2 cm and 10 cm, for example between 2 cm and 5 cm, for example equal to 5 cm.

[0168] For example, each flexible guide plate is a 3 cm x 3 cm square.

[0169] The second, third and fourth embodiments have been described in a unique manner relative to each other. However, it is noted that these three embodiments can be combined in the same lighting module, in particular:

[0170] - the second embodiment and the third embodiment may be combined: at least two flexible guide plates are superimposed, and one of the two flexible guide plates is associated with two light injection guides adapted to selectively inject light into two different portions of the guide plate, two patterns being etched in the two portions respectively;

[0171] - the second embodiment and the fourth embodiment may be combined: at least two flexible guide plates are placed adjacent to each other, and one of the two flexible guide plates is associated with two light injection guides adapted to selectively inject light into two different portions of the guide plate, two patterns being etched in the two portions respectively;

[0172] The third embodiment and the fourth embodiment may be combined: at least two flexible guide plates are placed adjacent to each other, and one of the two flexible guide plates overlaps with a third flexible guide plate of the light emitting module;

[0173] -The second embodiment, the third embodiment and the fourth embodiment can be combined: at least two flexible guide plates are placed adjacent to each other, and one of the two flexible guide plates is overlapped with a third flexible guide plate of the light-emitting module, and one of the three flexible guide plates is associated with two light injection guides, which are adapted to selectively inject light into two different parts of the guide plate, and two patterns are respectively etched in the two parts.

[0174] [ Figure 6 ] depicts an interior device 600 for a motor vehicle according to an embodiment of the present invention.

[0175] The interior device 600 according to the invention comprises a light emitting module 100, 300, 400, 500 according to one of the above embodiments or according to a combination of several of the above embodiments and an outer surface 620 to which the light emitting module 100, 300, 400, 500 is attached.

[0176] External surfaces are surfaces that are accessible to a user when the internal device is installed in a vehicle. External surfaces are thus distinguished from internal surfaces that are accessible only by removing the device or when the device is not installed in a vehicle.

[0177] "Interior" equipment refers to any equipment comprising at least one exterior surface that is intended to be accessible to a user of the interior of a motor vehicle.

[0178] There is no limitation on the manner in which the light emitting modules 100 , 300 , 400 , 500 are attached to the outer surface 620 .

[0179] The light module 100, 300, 400, 500 can be inserted, for example, into a frame or support of the device 600, which is provided for this purpose, in particular has a shape complementary to the light module 600 and is held in place by adhesive bonding, screwing, clamping, clipping, or any other type of holding means or attachment means. Alternatively, the light module 100, 300, 400, 500 is directly bonded to the outer surface 620 of the device 600.

[0180] The device 600 may further include a control element 640, which may be one of the control elements described above with reference to the four embodiments. Thus, the control element 640 may be external to the light emitting module 100, 300, 400, 500. Alternatively, as described above, the control element may be internal to the light emitting module 100, 300, 400, 500.

[0181] The control element 640 may include a processor configured to communicate unidirectionally or bidirectionally with a memory, such as a random access memory (RAM) or a read-only memory (ROM) or any other type of memory (flash memory, EEPROM, etc.), via one or more buses or via a wired connection. Alternatively, the memory includes several of the above-mentioned types of memories. Preferably, the memory is a non-volatile memory. The processor is adapted to execute instructions stored in the memory for implementing one or more animations based on the reception of animation commands, or for controlling the projection of patterns based on touch input data from the touch-sensitive layer 610 described below. Alternatively, the processor may be replaced by a microcontroller designed and configured to implement one or more animations based on the reception of animation commands, or to control the projection of patterns based on touch input data from the touch-sensitive layer 610 described below.

[0182] Optionally, the internal device 600 may further include a touch-sensitive layer 610 adapted to receive a touch input from a user. The touch input is not limited, and the touch input may be a tap, a tap and hold, a flick, a slide, a two-finger tap, a pinch to zoom in or out, two consecutive taps, or any other type of touch input.

[0183] There is also no limitation on the technology associated with the touch-sensitive layer 610, which may be, for example, of the capacitive type. Alternatively, the touch-sensitive layer 610 is of the resistive type. This technology is well known and will not be described in more detail in this specification.

[0184] The lighting modules 100, 300, 400, 500 are adapted to form one or more patterns 630 including a first symbol 631 such as a + symbol and a second symbol 632 such as a - symbol. As explained above, examples of these patterns are given for illustrative purposes only.

[0185] Depending on the embodiment in question, pattern 630 may be projected by one or more flexible guide plates:

[0186] In the first embodiment, the pattern 630 is formed by a single flexible guide plate of the light emitting module 100;

[0187] - In a second embodiment, the pattern 630 is formed by a single flexible guide plate of the light module 300, but each symbol 631 and 632 can be projected by selectively injecting into two injection elements opposite different sections of the edge of the flexible guide plate, in such a way that the symbols 631 and 632 are projected in two different areas. Thus, the projected pattern can include one symbol, another symbol, two symbols or no symbol. More generally, selectively injecting into one injection element, another injection element or two injection elements makes it possible to dynamically change the projected pattern 630;

[0188] - In a third embodiment, the pattern 630 is formed by superposition of at least two flexible guide plates of the light module 400. According to a first example, each flexible guide plate produces the same pattern 630, but with different colors, which makes it possible to dynamically change the color. According to a second example, the first flexible guide plate is adapted to project a first symbol 631 according to a first color, and the second flexible guide plate is adapted to project a second symbol 632 according to a second color that is the same as or different from the first color, and the injection of light is selectively controlled between the two flexible guide plates in such a way that the projected pattern 630 is dynamically changed, as in the second embodiment;

[0189] In a fourth embodiment, the pattern 630 is formed by a matrix of at least two flexible guide plates adjacent to each other. Thus, according to a first example, the first flexible guide plate projects a first symbol 631 and the second flexible guide plate projects a second symbol 632. Alternatively, the light module 500 comprises more than two flexible guide plates and each flexible guide plate is adapted to project a portion of the symbols 631 and 632. For example, each symbol can be generated by four flexible guide plates.

[0190] When the pattern 630 forms several symbols, such as [ Figure 6 ], each symbol may be projected in a given area of ​​the light emitting modules 100, 300, 400, 500. The first symbol 631 may be projected in a first given area on the right side of the light emitting module, and the second symbol 632 may be projected in a second given area on the left side of the light emitting module.

[0191] According to an embodiment, the touch sensitive layer 610 may include touch sensitive areas corresponding to the first given area and the second given area, respectively. Therefore, the first touch sensitive area may overlap with the first given area, and the second touch sensitive area may overlap with the second given area. The touch sensitive area and the given area of ​​the light emitting module may only partially overlap.

[0192] Therefore, when the user touches the first symbol 631, a first touch input may be received in the first touch-sensitive area, and when the user touches the second symbol 632, a second touch input may be received. When the first touch input is received, the first touch input data is transmitted to the control element 640, and when the second touch input is received, the second touch input data is transmitted to the control element 640.

[0193] The control element 640 is adapted to control the source of the light emitting module 100, 300, 400, 500 according to the received touch input data. For example:

[0194] - The control element 640 may change the luminous intensity of the pattern according to the touch input data. For example, the control element increases the luminous intensity of the projected pattern 630 when receiving the first touch input data, and decreases the luminous intensity of the projected pattern 630 when receiving the second touch input data;

[0195] - The control element 640 can change the color of the pattern 630 according to the received touch input data;

[0196] -The control element can activate or deactivate certain light sources based on the received touch input data.

[0197] Alternatively or in addition, the control element 640 may control another device of the vehicle based on the touch input data ([ Figure 6 ] is not shown). For example, the volume of the speaker can be increased or decreased according to the touch input data. Alternatively, the temperature of the vehicle air conditioning / heating system can be controlled based on the received touch input data.

[0198] More than two symbols may be set in more than two given areas associated with more than two touch-sensitive areas, and the control element 640 is adapted to control the lighting module 100, 300, 400, 500 or other devices according to more than two touch input data.

[0199] There is no limitation on the type of internal device 600 discussed.

[0200] The interior device 600 may be, for example, a dashboard of a motor vehicle. For example, the interior device may be a dashboard on the passenger side of a motor vehicle. Thus, the interior device 600 may be advantageously used to control other devices in the vehicle, such as a heating / air conditioning system or speakers. Where the interior device is a dashboard, the interior device may include an inflatable safety device, such as an airbag, for example, below the outer surface 620 of the device 600 and within the [ Figure 6In this case, since the light emitting module includes one or more thin flexible guide plates, the light emitting module 100, 300, 400, 500 can be torn by the inflatable safety device in the event of a vehicle collision, which makes it possible to perform an ambient lighting function or an aesthetic lighting function, or control a device of the vehicle without compromising the driving safety features provided by the inflatable safety device.

[0201] The interior device 600 may alternatively be a seat for a motor vehicle, in particular the rear part of a seat, in such a way that light is projected towards the rear passengers of the vehicle. The lighting modules 100, 300, 400, 500 may be integrated into the back of a seat headrest or into the back of a seat body. Alternatively, the interior device 600 may be a motor vehicle roof or a motor vehicle rear shelf.

[0202] The invention is not limited to the embodiments described above by way of example; it extends to other variants.
