    DESCRIPTION
    Illumination device for interior panel of vehicle
    OBJECT OF THE INVENTION
    The purpose of the present patent application is to provide a lighting device for the interior panel of the vehicle according to claim 1, which incorporates notable innovations and advantages.
    BACKGROUND OF THE INVENTION
    The lighting concept generating a 3D effect (three dimensions) is known and applied in lighting devices for vehicle headlights currently on the market. It is also noted that its application has been to date mainly in subsequent pilots. In addition, the patents related to this effect show, either by the drawings or by the way in which they use the technology, which are aimed at the implementation of a 3D effect on said subsequent pilots. That is why it is desired to apply for a patent with said 3D effect for the vehicle's interior, focusing on the technology used to the needs of an interior lighting, where the technical requirements differ greatly from the technical requirements for the exterior lighting.
    It is known from the state of the art, as reflected in WO2013113728, a rear light device for motor vehicles, comprising multiple LED type light sources. It is formed by a module that includes the following elements, from back to front, in the direction of the beam of light emitted by said LED, namely: a printed circuit board (PCB) comprising at least 3 LEDs and preferably at least 5 Functional LEDs by means of suitable printed circuits and an external power supply; a light guide; optical parts suitable for guiding and / or distributing the beams of one or more of said LEDs; a mirror optionally with transparent or perforated areas; at least one semi-transparent screen; as well as an optional housing to house all of said elements in a preferably sealed structure. The invention is suitable for the taillights of motor vehicles.

    It is therefore a light device focused on exterior light with different functions in the same housing, for example the function of braking signaling and light position. Specifically, the light arrives indirectly through the gluttony of light and other optical elements, the direction of light emission being the same as that of reflection. This forces to occupy more space and to use glues of light with elbows (in which important losses take place) to make arrive the light to all the points. On the other hand, the end of the light glutton is the one that introduces the light into the reflection zone, thus being a point light input. If different points of light entry are desired, a multitude of light glues are required that have at one end pointing towards the reflection zone.
    It is also known from the state of the art, as reflected in EP2390137, a lighting device comprising a light source and an optical unit, which is assigned to the light source. The optical unit comprises a reflective unit with a front mirror and a semi-reflective unit, arranged in the main radiation direction, between which the light is reflected producing the effect of continuous reflection.
    The idea is technically designed for exterior lighting, in particular for subsequent lighting. There is a direct emission of light, through lenses or optics, in order to perform a first brake light function. At the same time, the same light source is used to perform a second 3D effect function for position light. For this, some beams of light enter the zone of reflection in a totally direct way, that is, without optics or intermediate treatments.
    It is also known in the state of the art, as reflected in WO2014177816, a lighting device for a motor vehicle. It consists of a combination of means essentially composed of: a) a reflection zone in which the 3D effect is produced composed of a reflective surface and a semi-transparent surface and, b) opaque parallel plates facing each of the emitters of LED light, where said plates define a channel that conducts light from the emitter to the reflection zone. As a particular feature of the patent, it is observed that the light emitter is inclined with respect to the axis defined by the opaque parallel plates, so that the light strikes not perpendicularly on the conductive channel of light, so that the dispersion of the incident light in the reflection zone.

    It is observed in said device that the light indirectly reaches the reflection zone, having passed a channel to homogenize the light and a terminal to increase the brightness. Also for this case, a multitude of parallel opaque plates are needed to emit light inside the reflection zone, and a multitude of light emitters, each light emitter having its own channel and its terminal.
    It is also known in the state of the art, as reflected in EP2336632, a device that has a semi-transparent screen and a reflective screen that form a cavity, one of whose surfaces is concave or convex. It comprises a light source that includes a support arranged in such a way that the light rays penetrate the cavity along a main direction oriented towards a space to be illuminated. The screens are arranged in relation to a direction of emission of the light source such that a portion of the light rays emitted by the light source is released outside the cavity, without crossing a semi-reflective area of the screen . Therefore, there is also in this case a direct emission of light and an indirect emission through the reflection cavity.
    Thus, it is seen that there is still a need for a lighting device that, by applying the concept of reflection and semi-reflection, creates a 3D effect towards the user, particularly in the interior door panel moldings.
    DESCRIPTION OF THE INVENTION
    The present invention deals with the application of the lighting concept that generates a 3D effect inside the automobile vehicles, specifically applied in interior panels, where the lighting technical requirements to be fulfilled are not as demanding as outside the vehicle. Thus, by way of example, it will not be necessary for the light beams emitted by the light emitter to directly illuminate the exterior of the illumination module, in order to meet the necessary intensity and illumination levels. Likewise, the number of components for the emission and conduction of the light beams may be significantly reduced. On the contrary, other technical requirements come into play such as the design of the generated 3D effect, the little space available for the lighting module, the high quality perceived by the user when observing the lighting module, both with lighting on and with lighting off ...

    The 3D effect is based on having a 100% reflective surface facing a semi-light transmitting surface, substantially 50%. That is, it allows the light beams to pass approximately 50% of the incidents, the other 50% being reflected. In this way, the semi-light transmitting surface emits part of the incident light beams outwards and reflects other light beams inwards. The reflected beams impact the 100% reflective surface again and return to the semi-transmitting surface, and thus repeatedly, achieving the effect of 3D image, seeing from the outside the same silhouette of repeated light an indefinite number of times, each being repetition of a lower intensity. In this way, a depth effect is observed.
    Thus, and more specifically, the lighting device for the interior panel of the vehicle comprising at least one light transmitting means which runs substantially along the interior panel of the vehicle, at least one light source linked to at least one transmitting means of light and facing one end of the at least one light transmitting means, so that the at least one light transmitting means conducts the light emitted by the at least one light source in a direction of light emission, a partially mask transparent covering at least partially the light transmitting means, so as to allow the passage of light through at least one transparent area of the partially transparent mask, a reflective surface attached to the partially transparent mask, a semi-transparent surface attached to the partially transparent mask, a reflection area, defined between the reflecting surface and the semi-transparent surface, so that it receives light through the at least one transparent area of the partially transparent mask, a smoked molding adjacent to the semi-transparent surface so as to allow light to pass through the smoked molding to the outside of the inner panel in an emission direction, where the smoked molding, the reflecting surface, the semi-transparent surface and the direction of light emission are substantially parallel to each other.
    In this way, the lighting device emits light into the interior of the room obtaining an essentially elongated illuminated surface. Thus, the light is emitted by the at least one light source and conducted by the at least one light transmitting means in a substantially constant and homogeneous manner along its longitudinal dimension, which follows substantially the same direction as the direction light emission by
    5

    of the light source. Thus, a first and important difference is observed with respect to exterior lighting concepts, where the direction of light emission is essentially perpendicular to the reflecting surface and the semi-transparent surface. The lighting modules achieved in the state of the art therefore require an important depth, since all the components are located one after the other in the direction of light emission. It is easily understood that, in the interior of the room, especially in door panels or instrument panels, this depth does not exist, so a shallow illumination module is required, while achieving an elongated illuminated surface, in addition to minimize components and module costs.
    On the other hand, said configuration makes it possible to minimize the number of light emitters, a light intensity not as high as outdoors being required indoors. Another additional advantage to be considered in said configuration is that, being substantially parallel to each other the smoked molding, the reflecting surface, the semi-transparent surface and the direction of light emission, a correct reflection is achieved without distortions in the 3D drawing emitted towards The interior of the room.
    Mention also that the functions of the gluttony of the light are the habitual ones to transmit the light and to look for a maximum homogeneity of light in all its length. In the present invention the gluttony of light does not present angular changes of direction or corners, so that there is no loss of light at these points. As for the reflective surface it is a 100% reflective surface which bounces all the incident light beams. It is in the area or zone of reflection, between the reflecting surface and the semi-transparent surface, that the multiple reflections of the light beams are produced in order to produce the 3D effect.
    In addition, a component not used in lighting devices known in the state of the art that implement a 3D illumination is the use of a smoked molding. This smoked surface has a finish that allows the passage of light from the reflection area to the outside but, on the contrary, does not allow the light beams to penetrate from the outside. This point is especially advantageous for not introducing light distortions in the reflection area, obtaining a clear and clear drawing, in addition to not allowing to see from the outside the components that form the lighting device of the present invention, so that it favors to the good finish of the interior of the vehicle, essential requirement of any component located in the interior of a vehicle.

    According to another aspect of the invention, the direction of emission is in a plane substantially perpendicular to the semi-transparent surface. In this way, the light that strikes from the reflection area towards the semi-transparent surface crosses it completely towards the outside of the device, that is, towards the interior of the room, minimizing the effect of light losses.
    It should be mentioned that the reflection area is also defined by the transparent area of the partially transparent mask, the reflection area being adjacent to the at least one transparent area of the partially transparent mask. It is through said transparent area of the partially transparent mask that the light conducted through the light transmitting means is transferred to the reflection area, allowing the lighting device to function. Said transparent areas are located along the light transmitting medium, selecting the light entry zones inside the reflection area. Thus, you can select the drawing or image from which you want to generate the 3D effect by modifying the transparent areas of the partially transparent mask. In addition, the reflective surface and the semi-transparent surface are located at the band and band of the transparent area of the partially transparent mask. Thus, the transparent area of the partially transparent mask is between the reflective surface and the semi-transparent surface, collecting all the light in the reflection area.
    In a preferred embodiment of the invention, the reflecting surface, the semi-transparent surface and the smoked molding are superimposed on each other in the direction of light reflection. In this way, the transmission of light into the interior of the vehicle does not suffer almost any loss or unwanted distortion. Advantageously, the surfaces may have a special geometry, different from a rectangular geometry. The proposed configuration allows the said components to have this particular geometry adapted to the interior design of the vehicle, fulfilling the requirements that the geometry must be common for the three components, as well as essentially parallel to each other.
    In a preferred embodiment of the invention, the inner panel comprises as an outer element the smoked molding, the semitransparent surface being between the reflective surface and the smoked molding.

    Advantageously, the partially transparent mask comprises an inner face adjacent to the matte white light transmitting medium. In this way it is sought that there is no loss of light. Consequently, the light transmitting means or gluttony of light will be in full length enclosed by white and matt walls that increase the homogeneity of light in its interior avoiding the loss or absorption of light in said area. It is therefore sought to minimize light losses in the operation of light transmission due to the need to minimize the number of light emitters. Thus, there is no light leakage thanks to the mask, since it wraps the light transmitting medium, in addition to increasing the homogeneity of the light by finishing the matt white finish of its interior walls.
    On the other hand, the partially transparent mask comprises an outer face adjacent to the black light reflection area, in order to absorb all the scattered light beams other than those that participate in the 3D effect.
    In a preferred embodiment of the invention, the partially transparent mask material is ABS (acrylonitrile butadiene styrene) so that it is impact and shock resistant, while favoring a correct transmission of light through it.
    In a preferred embodiment of the invention, the light passing through the partially transparent mask is by elimination of the black color of the outer face by means of a laser process, so that at least one transparent area of passage is defined or obtained. light to the reflection zone. More particularly, it is about applying laser to the mask in order to obtain a passage of light between the cavity of the gluttony and the area or zone of reflection. It is intended that the light beams pierce the molding only through this area. Thus, with the change of the geometry of the laserated graph, one or another geometry of the graph can be obtained, which will be reflected multiple times and seen by the user. Therefore, a technique is used that has no restrictions on the possible graphics to obtain. Specifically, with the laserado the layer of black paint is removed forming the drawing through which the light will pass. In addition, this technique achieves the passage of homogeneous light at the color level. Alternatively, a die cut could be used, which would also allow the direct passage of light, but provide surface defects and non-homogeneities. Any defect or scattering of light transfer it to the reflection zone so it is very important that there is a material that absorbs these defects. White ABS is ideal for

    Provide this homogeneity. Additionally, the operation is independent of the color of the LED. Therefore, any generated color would pass with the same precision and quality.
    The triple functionality of the partially transparent mask in the lighting device of the present invention is highlighted. Thus, it allows to avoid loss of light by wrapping the light transmitting medium with essentially white and matt walls, it allows the transmission of light from the light transmitting medium to the reflection area only in the transparent areas of the partially transparent mask, achieving a high definition in the desired drawing and, lastly, to prevent unwanted beams of light from participating in the 3D effect by means of a black finish on the surface adjacent to the reflection area, preventing the desired drawing from being distorted and not damaged.
    Advantageously, a cavity defined at least partially by the partially transparent mask envelops the light transmitting means. In this way, the light transmitting means is closed, avoiding losses and light leaks, and light can only be transmitted through the transparent area.
    In a preferred embodiment of the invention, the smoked molding is in black smoked finish, so that the user does not see the elements that make up the interior of the molding. In addition, a good design and finish is achieved, in accordance with the interior requirements of a vehicle's interior.
    Advantageously, the smoked molding is in polycarbonate with black dye, so that great impact resistance, great transparency, high resistance to thermal deformation, high dimensional stability, and good electrical insulation properties are achieved. Alternatively, said smoked molding is of PMMA of high hardness so as to avoid possible scratches and is of smoked translucent surface finish, so that the exterior appearance is dark and preferably bright. Thus, when the at least one light source is turned off, the smoked molding behaves like an opaque element (which does not allow to see through it) and when the at least one light source is on, it allows the passage of light and leaves visible the ornament or drawing generated in the area of reflection. In addition, it is the element that covers and protects the internal components of the lighting device.

    According to another aspect of the invention, the smoked molding comprises a semi-reflective layer based on a chrome varnish on the face facing the reflective surface so that the reflection area is defined between the reflective surface and the smoked molding. Thus, in a preferred embodiment, the semi-transparent layer or surface would be a chrome varnish that allows semi-reflection to be performed. In this way a saving of components is achieved, the semi-transparent surface and the smoked molding being a unique component, the exterior material also presenting the characteristics of good exterior surface finish, light transfer from inside to outside, no light passing from outside to inside.
    In a particular embodiment of the invention, the lighting device comprises a light source facing each end of the light transmitting means, so that a higher light intensity is achieved, while a greater homogeneity over the entire length of the device.
    It should be mentioned that the semi-transparent surface has a reflection between 40% and 60% of the incident light beams, so that the first incident light beams on the semi-transparent surface are reflected to the reflection area, and a few light beams incidents on the semi-transparent surface are transmitted through the semi-transparent surface in the direction of emission. In this way, and through multiple reflections the effect of depth and 3D effect is achieved.
    Consequently, a concept of reflection between a reflective surface and a semi-transparent surface is adapted in order to create multiple reflections and a visual effect in 3D form to the needs and requirements of interior lighting of the vehicle, the change of directions being especially relevant of the light beams in order to minimize the interior space occupied by the lighting device, in addition to a specific selection of the light beams to the reflection area through the transparent mask in order to create a specific and specific drawing from which to generate the 3D effect.
    The attached drawings show, by way of non-limiting example, a lighting device for an interior vehicle panel, constituted in accordance with the invention.

    DESCRIPTION OF A PREFERRED EMBODIMENT
    In view of the aforementioned figures and, according to the numbering adopted, an example of preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
    The present invention aims at obtaining a novel lighting device for interiors of a vehicle. Thus, as can be seen in Figure 1, the lighting device of the present invention can be used for the generation of a decorative illuminated surface of a panel of a vehicle door. The present lighting device generates an illuminated drawing or silkscreen with a depth or 3D effect
    Thus, as seen in Figures 2 and 3, the lighting device for the interior panel of the vehicle comprises at least one light-transmitting means 2 which runs substantially along the interior panel 1 of the vehicle, at least one source of light 22 linked to at least one light transmitting means 2 and facing one end 21 of the at least one light transmitting means 2, so that the at least one light transmitting means 2 conducts the light emitted by the at least one source of light 22 in a direction of light emission 71, a partially transparent mask 5 that at least partially covers the light transmitting means 2, so as to allow the passage of light through at least one

    transparent area 51 of the partially transparent mask 5, a reflective surface 3 attached to the partially transparent mask 5, a semi-transparent surface 4 attached to the partially transparent mask 5, a reflection area 34, defined between the reflective surface 3 and the semi-transparent surface 4, so that it receives the through light through the at least one transparent area 51 of the partially transparent mask 5, a smoked molding 6 adjacent to the semi-transparent surface 4 so as to allow the passage of light through the smoked molding 6 outside the inner panel 1 in an emission direction 73, where the smoked molding 6, the reflecting surface 3, the semi-transparent surface 4 and the light emission direction 71 are substantially parallel to each other.
    Usually, and in a preferred embodiment, the interior moldings or panels 1 in which this 3D effect is to be generated are elongated and narrow. In addition, in order to save on the number of light emitters or light sources 22 and ensure high homogeneity of light throughout the molding, a light glutton or light transmitting means 2 is used that runs along the entire molding or inner panel 1. For this, and in an advantageous embodiment, a light source 22 is used at each end of the light glutton or light transmitting means 2, pointing and emitting the light directly on each end of the glutton of light or light transmitting medium 2. Normally, two LEDs are used located at each end of the light guide or light transmitting means 2, and facing each other. In this way, a compact module is generated, which occupies a minimum space, and with a minimum energy consumption but, at the same time, generates a precise, homogeneous and striking illumination for the user.
    More particularly, as seen in Figures 2 and 3, the emission direction 73 is in a plane substantially perpendicular to the semi-transparent surface 4.
    On the other hand, as seen in Figures 2 and 3, the reflection area 34 is also defined by the transparent area 51 of the partially transparent mask 5, the reflection area 34 being adjacent to the at least one transparent area 51 of the partially transparent mask 5.
    Additionally, as seen in Figures 1, 2 and 3, the reflecting surface 3, the semi-transparent surface 4 and the smoked molding 6 are superimposed on each other in the direction of light reflection 73. According to a particular embodiment of the invention, yes the

    Smoked molding 6 integrates in the same component the semi-reflective or semi-transparent surface 4, it must be parallel only with the reflecting surface 3.
    According to another aspect of the invention, as seen in Figures 1, 2 and 3, the inner panel 1 comprises as an outer element the smoked molding 6, the semi-transparent surface 4 being between the reflecting surface 3 and the smoked molding 6.
    More specifically, as can be seen in Figures 2 and 3, the partially transparent mask 5 comprises an inner face 53 contiguous to the light-transmitting means 2 of a matt white color.
    According to a preferred embodiment of the invention, as seen in Figures 2 and 3, the partially transparent mask 5 comprises an outer face 52 contiguous with the reflection area 34 of black light. According to a particular embodiment of the invention, the black color is a layer of black paint. In this way, the partially transparent mask piece 5 has a black outer layer paint (similar to the black of the keyboard keys).
    More particularly, as seen in Figure 3, the partially transparent mask material 5 is ABS (acrylonitrile butadiene styrene). In a specific embodiment the material is white ABS.
    According to another aspect of the invention, as can be seen in Figures 2 and 3, the light passing through the partially transparent mask 5 is by elimination of the black color of the outer face 52 by means of a laser process, so that it defines the at least one transparent zone 51 of passage of light to the reflection zone 34.
    On the other hand, as seen in Figures 2 and 3, a cavity 54 defined at least partially by the partially transparent mask 5 envelops the light transmitting means 2.
    More specifically, as seen in Figure 1, the smoked molding 6 is in a black smoked finish.

    Additionally, as seen in Figure 1, the smoked molding 6 is in polycarbonate with black dye.
    According to a preferred embodiment of the invention, as seen in Figures 2 and 3, the smoked molding 6 comprises a semi-reflective layer based on a chrome varnish on the face facing the reflecting surface 3 so that the reflection area 34 is defined between the reflective surface 3 and the smoked molding 6.
    More particularly, the lighting device comprises a light source 22 facing each end 21 of the light transmitting means 2.
    According to a specific embodiment of the invention, as seen in Figures 2 and 3, the semi-transparent surface 4 has a reflection between 40% and 60% of the incident light beams, so that the first incident light beams on the semi-transparent surface 4 are reflected to the reflection area 34 and a few second beams of light incident on the semi-transparent surface 4 are transmitted through the semi-transparent surface 4 in the direction of emission 73. The semi-transparent or semi-reflective surface 4 is parallel to the reflective surface 3, also called inner cover with mirror.
    Going into more detail of the operation of the present invention, a first light source 22 is shown in FIG. 2 facing the light transmitting means 21. It is noted that at the opposite end of the light transmitting means 21 there would be a second light source. 22, so that the light transmitted by the light transmitting means 21 along the direction of light emission 71 is more homogeneous and constant. The light-transmitting means 21 is preferably a circular elongate, essentially elongated, and minimizes direction changes in order to avoid light loss in the elbows.
    Therefore, the light is transmitted along the light transmitting means 21. In order to minimize the loss and leakage of light, the light transmitting means 21 is covered by an inner face 53 of the partially transparent mask 5 , so that it forms a cavity 54. It is therefore sought that, by means of the white walls that form the inner face 53, light beams do not escape from the cavity 54, improving the efficiency in the transmission of light, as well as its homogeneity.

    The light escapes only from the cavity 54 through the at least one transparent zone 51 of the partially transparent mask 5. Thus, those zones are desired by which it is desired that the light enters the reflection area 34 in order to limit the drawing or silkscreen that you want to generate. As can be seen in Figure 2, the transparent zone 51 is, by way of example, essentially an elongated rectangle formed in the lower zone of the reflection area 34. Thus, the light is transmitted from the cavity 54 to the reflection area 34 essentially in a direction of light transmission 72 through the transparent areas 51. Note that these transparent areas 51 can have any desired geometry, thus varying the pattern or screenprint to be represented.
    In addition, as seen in Figure 3, the light beams are introduced into the reflection area 34 and the reflections begin in order to generate a 3D effect. Thus, a succession of reflections occurs between the reflecting surface 3 and the semi-transparent surface 4. Thanks to the semi-reflection characteristic of the semi-transparent surface 4, part of the light beams are reflected towards the reflecting surface 3 and the remaining ones are emitted towards smoked molding 6 and outward. Thus, a succession of drawings is generated that reproduce the transparent zone 51, each of them having a lower intensity and dimension, thus generating the effect of depth or 3D.
    Note from the section of Figure 3 the minimum space occupied by the lighting device of the present invention, especially in the direction of reflection 73 or depth of the device, being especially relevant for vehicle interiors.
    The details, shapes, dimensions and other accessory elements, as well as the components used in the implementation of the lighting device for the interior panel of the vehicle may be conveniently replaced by others that are technically equivalent, and do not depart from the essentiality of the invention nor of the scope defined by the claims included below of the following list.
