    DESCRIPTION

    Lighting device for exterior cover of one side of a vehicle

     5
    OBJECT OF THE INVENTION

    The object of the present patent application is a lighting device for the outer cover of a side of a vehicle according to claim 1, which incorporates notable innovations and advantages. 10


    BACKGROUND OF THE INVENTION

    At present, various exterior lighting devices are known located at 15 different points of the vehicle body. Thus, it is known from the state of the art, as reflected in document US20070295043, an actuator for unlocking doors of a keyless vehicle. The actuator includes a housing that defines a periphery and an interior volume. A cover plate is fixedly secured to the housing at its periphery. The cover plate defines an inner surface versus the inner volume and an outer surface opposite the inner surface. The outer surface is opaque under standard ambient light conditions. The drive device also includes a switch that is operatively connected to the inner surface of the cover plate, in a defined location to toggle the device between the ON and OFF conditions. The drive device 25 further comprises a presence sensor to identify when an operator is adjacent to the cover plate. An interior light illuminates the cover plate in such a way that the light passes through the cover plate and the outer surface, illuminating the switch towards the operator.
     30
    It is noted that said document presents a set of illuminated capacitive actuators to enter a code that allows the vehicle to be unlocked without a key. It has LED diodes that emit the light in a direction opposite to the projection towards the operator, through the filling of a cavity of light and allow its output only by an intermediate element with a graph, located between the sensors and the cover element . 35 The cover is tinted black. However, it is observed that the generation of light is not optimal: LEDs emit light in a direction opposite to that of projection. It seeks to fill the interior volume of light, a fact that leads to many losses and inefficiencies, resulting in a low quality in the homogeneity of the projected light, as well as a low intensity of projected light. 5

    It is also known in the state of the art, as reflected in document US9016910, a vehicle finishing component for interior and exterior surfaces, comprising: a partially light-transmitting substrate; an adjacent lighting source, the lighting source being operable between a lighting state and an unlit state; and a layer of variable transmissivity that transmits light on a first surface of the substrate. The variable transmissivity layer includes an opaque portion which does not transmit light, and a light transmitting part. The light transmitting part comprises one or more defined lines through the opaque part, arranged to define perceptible indications when the light source is in its illuminated state. 15 Each line is visually imperceptible to the naked eye when the light source is in its unlit state.

    Specifically, the light of the LED emitter is oriented in the same direction and direction as the projection of the logo, the mask or intermediate element with a graphic, allowing the passage of light 20 through a transparent area. However, there are clear differences in terms of lighting and the generation of a homogeneous lighting concept. In particular, whenever an LED emits in the same direction as that of propagation, very bright areas (just those facing the emitter) and areas not so well lit (where there is no emitter just behind) are perceived. Golden and arches are produced, making it impossible for the image to be homogeneous.

    It is also known from the state of the art, as reflected in EP2062784, an exterior vehicle component that includes a first member having a decorative surface arranged in an outer portion thereof for the transmission of light, the first member further includes a first coupling part, a second member having a second coupling part that is mounted with the first coupling part of the first member, the first member and the second member forming a double layer structure. It also includes a light emitter. The light goes out in response to a power supply provided from the vehicle. 35


    It is noteworthy that the solutions presented could only be used with the engine stopped, since none of them would meet the homologation requirements for a vehicle in motion that are detailed below. In this regard it is worth mentioning that light is a transverse electromagnetic radiation, that is, that the oscillation of the electromagnetic field is perpendicular to its propagation. In general, conventional light sources, such as the sun, emit light with electric fields in any direction to the direction of propagation (but always perpendicular to it).
     10
    In Figures 3A and 3B, the technical requirements for homologation of the vehicles are observed, according to which there can be no direct light emitter that can be seen in the following areas marked with the vehicle with the engine running, similar to some cones of surface, at a distance of 25m. Therefore, an observer who is inside the areas marked in Figures 3A and 3B, cannot glimpse any red light emitter (towards the front area of the vehicle) and white light emitter (towards the rear area of the vehicle) that is not intended for the functions of lighting, braking, signaling of the march ... Consequently, it is necessary to look for an embodiment that allows the vehicle to be homologated while projecting the logo or graphic to illuminate during the march or circulation of said vehicle. twenty

    Thus, it is seen that there is still a need to have a lighting device for the outer cover of one side of a vehicle, as a trim, that has good homogeneity properties in the light emitted outward, and that meets the technical requirements for approval of the vehicle in terms of its projection towards the lateral areas and the vehicle in motion.


    DESCRIPTION OF THE INVENTION
     30
    The purpose of this idea is to project an illuminated logo at some point on the side of the vehicle, preferably on the plastic elements of the doors, either at the front or rear door, making the minimum possible alterations to the current structure of said door, such as , for example, by means of an LED emitter that illuminates a logo through a window on the exterior door trim. Consequently, it is not the object of the present idea to generate a beam of light for the lighting of the lateral area of the vehicle, but to illuminate a logo located on the side of the vehicle so that it can be glimpsed in all kinds of conditions.

    As mentioned, light is a transverse electromagnetic radiation, that is, that the oscillation of the electromagnetic field is perpendicular to its propagation. However, by different physical mechanisms, a single oscillation direction can be filtered, in this state the light is polarized.

    Thus, polarized light is one that has a certain direction of oscillation. There are three 10 types of polarized light: linear, circular and elliptical. A polarizing filter can be imagined as a grid that only allows the passage of light that oscillates in the plane parallel to the normal vector to the surface of the grid. Light transmitted to the other side of the polarizing element is considered polarized light. In reality, the commercial polarizing filter consists of a polymer chain stretched to the limit, so that the molecules act as a grid that strongly absorbs a polarized component of light and is very transparent to the other component, as described by Malus's Law. Thus, a polarizing element comprises walls that restrict the direction of light output, closing the field in which the light is projected.
     twenty
    Thus, and in more detail, the invention consists of a lighting device for outer cover of a side of a vehicle, wherein the vehicle comprises a structural panel of the outer cover, where the structural panel comprises an opening, and where the device for lighting comprises a housing facing the opening and defining an interior volume between the housing and the opening of the structural panel, at least one light emitter arranged in the interior volume and operable in a first on or a second off state, a photolith with at least one graphic element, where the photolith is arranged between the at least one light emitter and the structural panel, and where the outer shell is partially opaque, so that it allows visualizing the at least one graphic element, where the lighting device comprises at least one light orientation means 30 so that the light emitted by the at least one light emitter is reorient tata towards the opening of the structural panel, and where the at least one light orientation means and the photolyte are housed in the inner volume between the housing and the opening of the structural panel and are arranged parallel and superimposed on each other. In this way it is possible to project an image or graphic configuration determined by the photolithic element to the outside of the vehicle, while said image appears to be substantially homogeneous in appearance, without areas brighter than others, and in such a way that the Image is projected according to an orientation substantially perpendicular to the vehicle body.

    It is observed that by means of the light orientation means, the angle or direction of the light beams is modified, so that a high homogeneity of the projected light is advantageously achieved in a minimum available space. This requirement is detailed later.

    More in particular, the at least one light orientation means is a light guide, wherein said light guide preferably consists of a flat plate through which a greater sharpness and quality of the generated image is achieved. The light guide advantageously presents a distribution of the light emitted by the at least one light emitter in a homogeneous manner throughout its surface. Thus, there are no golden and / or arcs, which prevent the transmitted light from being homogeneous. fifteen

    Advantageously, the light guide is an essentially flat plate, where the light guide comprises at least one light transmission surface and at least one end where the light emitted by the at least one light emitter strikes, so that the light less a light transmitting surface is substantially parallel to the photolith. Thus, and preferably, the light of the light emitter, preferably an LED, is introduced by one of the ends of the light guide, perpendicular to the direction of emission towards the outside of the vehicle body. It is important to note that the lateral area of the vehicle generally has very small volumes of space, especially in the direction transverse to the direction of advance of the vehicle. Consequently, and with the aim of not modifying the structure of, for example, a door, the lighting device of the present invention must have a reduced total thickness. Said arrangement of the light guide saves space, especially in the direction of exit of the light beam. Thus, the light emitter emits in a first direction, the light guide distributes the light received homogeneously throughout the transmission surface, and the light is redirected towards the side 30 of the vehicle in a second direction. The light transmitting surface means each of the two lateral faces of the flat plate. By end, each of the four sides of the flat plate is understood.

    According to another aspect of the invention, the light guide comprises a plurality of optical structures such that the light is dispersed particularly in a direction substantially perpendicular to the at least one light transmitting surface. Said substantially perpendicular direction will be either the one that goes inside the vehicle, or towards the outside. Thus, the light is redirected, at least in part, from the direction of emission of the light emitter, to the appropriate direction for the functionality of the present invention, that is, towards the outside of the vehicle body.

    The set of optical structures are arranged inside the light guide, next to both transmission surfaces, or faces of the flat plate. Said optical structures 10 are preferably made by laser. Its placement allows the dispersion of the light beams in any direction, especially towards the opening of the structural panel.

    On the other hand, the lighting device comprises a reflector element disposed between the housing and the light guide, so that the reflector element is substantially parallel to the at least one light transmitting surface of the light guide. Said reflector element bounces towards the outside of the vehicle, the light beams that go in the direction perpendicular opposite to the exit. In this way, greater light efficiency is achieved by reorienting most of the light emitted by the light emitter towards the opening of the structural panel, and therefore, towards the outside of the vehicle, optimizing the functionality of the lighting device.

    In a particular embodiment, the optical structures are preferably placed on the surface closest to the reflector element so that most of the light beams coming from the light emitter are reoriented outward without rebounding in the element itself reflector.

    Advantageously, the reflector element comprises at least one matt white surface. Consequently, at least the surface of the reflector element facing the light guide is matte white. In this way, the recovery of the light that is directed towards the rear area of the device and inside the vehicle is optimized, and direct it, with the least losses, towards the front area of the device, and outside the vehicle, to be illuminated.

    Additionally, the at least one light orientation means is a polarizing element, which allows the field of illumination of light emitted towards the outside to be closed in order to meet the aforementioned homologation requirements for restriction of the field of view, in order to that the lighting device may be switched on, projecting the logo or graphic element of the photolith during the running of the vehicle, in a direction 5 substantially perpendicular to the side of the vehicle. Therefore, the graphic element can only be seen from a position essentially facing the lighting device and essentially perpendicular to the direction of travel of the vehicle. Thus, an observer located in a front or front area of the vehicle, even if it is arranged on the sides of the vehicle, will not display the illuminated graphic device of the present invention, 10 thus complying with the approval requirements presented above.

    More specifically, the polarizing element is a film comprising a plurality of micro walls that restrict the direction of light output. Said micro walls act in the manner of a grid that strongly absorbs a polarized component of light, and is very transparent to the other component.

    According to another aspect of the invention, the photolyte comprises at least a first opaque zone and at least a second transparent zone. It is through the restriction of the light of the opaque zone, and the transmission of light through the transparent zone that the projection of a graphic element or logo to the outside is obtained.

    More specifically, the at least one first opaque zone is obtained by an application of a paint on the photolyte and the at least one second transparent zone is obtained by means of a laser operation to remove the paint. Thus, and by means of a laser operation, the paint is removed to give way to the transparent areas in the photolith, which can be a plastic substrate. This option by laser is cheaper than others, and has sufficient accuracy. A preferred embodiment is to achieve, through a single LED light emitter, different colors thanks to the placement of a plastic substrate of the photolith with a chromatic variety. 30

    According to another aspect of the invention, the partially opaque outer shell is of smoked black finish. The black smoked finish prevents seeing the interior and therefore the logo and the rest of the lighting device, while in on mode allows a light transmission that allows to appreciate the desired illuminated logo. 35

    It should be mentioned that the partially opaque outer cover is made by a bi-injection stage, in which the black smoked finish is injected into an outer face of the structural panel, said finish being obtained in a simple manner, and without a significant cost increase. 5

    In a first preferred embodiment of the invention, the lighting device successively comprises the housing, the reflector element, the light guide and the photolyte, facing the opening of the structural panel, and covered by the partially opaque outer cover, the element being reflector, light guide, photolyte and aperture 10 superimposed on each other. This arrangement of elements maximizes the performance of light efficiency, and homogeneity of the photolithic image, that is, the logo, which is transmitted abroad. On the other hand, this arrangement of elements offers various possibilities for positioning the light emitter, since it could be placed in front of each of the ends or edges of the light guide in its flat plate conformation. In addition, 15 it favors that the lighting device is compact and does not take up too much space, especially in the transverse direction, so that the structure of, for example, a door, is not affected.

    In a second preferred embodiment of the invention, the lighting device 20 successively comprises the housing, at least one light emitter, the photolith and the polarizing element, facing the opening of the structural panel and covered by the partially opaque outer cover, being the photolith, the polarizing element and the opening superimposed on each other. Said arrangement of elements maximizes the benefits of closing the field of illumination of light emitted towards the outside in order to comply with the 25 homologation requirements mentioned above so that the lighting device can be switched on while the vehicle is running.

    In a third preferred embodiment of the invention, the lighting device successively comprises the housing, the reflector element, the light guide, the photolith and the polarizing element 30, facing the opening of the structural panel and covered by the partially opaque outer cover , the reflector element, the light guide, the photolyte, the polarizing element and the opening being superimposed on each other. This arrangement of elements maximizes both the homogeneity and light efficiency benefits, as well as closing the light emission field. 35

Other features and advantages of said illumination device for outer cover of a side of a vehicle, object of the present invention, will be apparent from the description of a preferred, but not exclusive, embodiment illustrated by way of example. limiting in the accompanying drawings, in which:

    DESCRIPTION OF A PREFERRED EMBODIMENT
     30
    In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
    Thus, as can be seen in Figure 1, the invention relates to a lighting device intended to be housed in a side area of the vehicle. The function of this lighting device is to highlight and highlight a logo arranged on a lining on the side of a vehicle. These coverings are normally plastic parts that improve the surface finish of the vehicle and / or allow hiding areas to be seen from the outside, as an example, the plastic covers indicated on the A, B or C stud of the vehicle of the Figure 1.

    More in detail, as can be seen in the exploded one of Figure 2, the illumination device for outer cover 9 of a side of a vehicle, wherein the vehicle 10 comprises a structural panel 1 of the outer cover 9, where the structural panel 1 comprises an opening 11, and wherein the lighting device comprises a housing 3 facing the opening 11 and defining an interior volume between the housing 3 and the opening 11 of the structural panel 1, at least one light emitter 4 arranged in the inner and operable volume in a first state on or a second state off, a photolite 8 with at least 15 a graphic element 83, where the photolite 8 is arranged between the at least one light emitter 4 and the structural panel 1, and where the outer cover 9 is partially opaque, so that it allows visualizing the at least one graphic element 83, wherein the lighting device comprises at least one light orientation means 6 so that the light emitted by the at least one light emitter 4 is reoriented towards the opening 11 of the structural panel 1, and wherein the at least one light-oriented means 6 and the photolyte 8 are housed in the interior volume between the housing 3 and the opening 11 of the structural panel 1 and are arranged parallel and superimposed on each other. In this way a very compact structure is obtained, especially in the transverse direction or perpendicular to the direction of advance of the vehicle, which makes it possible not to alter the structure of the outer cover 25 9 and of the structural panel 1. Figure 2 shows a possible application of the present idea in the illumination of a logo arranged on the outer cover 9 of a vehicle B-pillar.

    The housing 1 encompasses the entire assembly and allows fixing to the substrate or inner structure 30 itself. It also allows light to not escape from the ends of the light guide. As seen in Figure 2, it is like a box with a concavity that encloses all intermediate concepts so that there are no movements, loss of light, etc ...

    Two alternatives are contemplated for the lighting device, that of only displaying the logo or graphic element 83 when the at least one light emitter is in a first on state, and, on the other hand, that of additionally displaying the logo or graphic element 83 when the at least one light emitter is in a second off state, by including, for example, a chrome or similar contour in the photolith 8. 5

    More particularly, as can be seen in Figure 2, the at least one light-guiding means 6 is a light guide 61. Preferably said light guide 61 is a methacrylate component with the same geometry as the photolyte 8 to be illuminated and arranged adjacently and just behind the photolyte 8, in the direction of light emission towards the opening 11 10 of the structural panel 1.

    More specifically, as seen in Figure 2, the light guide 61 is an essentially flat plate, where the light guide 61 comprises at least one light transmitting surface 611 and at least one end 612 where the emitted light strikes at least 15 a light emitter 4, so that the at least one light transmitting surface 611 is substantially parallel to the photolyte 8. In a preferred embodiment, the light emitter 4 is oriented towards the end 612 or lower side of the light guide, said light emitter 4 being therefore located at a lower level than said light guide 61.
     twenty
    According to another aspect of the invention, as seen in Figure 5, the light guide 61 comprises a plurality of optical structures 613 such that the light is dispersed particularly in a direction substantially perpendicular to the at least one light transmitting surface 611. In this way the light is emitted in a first direction and reflected in a second direction substantially perpendicular to the first direction. 25 In this way, a homogeneous illumination of the entire light transmission surface 611 is achieved, avoiding the creation of divergent aureas and light intensities in the logo 8, in addition to minimizing the space occupied by the lighting device, especially critical in the aforementioned transverse direction.
     30
    It should be mentioned that, as can be seen in Figure 2, the lighting device comprises a reflector element 5 disposed between the housing 3 and the light guide 61, so that the reflector element 5 is substantially parallel to the at least one surface of light transmission 611 of the light guide 61.
     35
    On the other hand, as seen in Figure 2, the reflector element 5 comprises at least one matt white surface 51.

    Additionally, as seen in Figures 2 and 4, the at least one light orientation means 6 is a polarizing element 71. 5

    More particularly, as seen in Figure 4, the polarizing element 71 is a film comprising a plurality of micro walls 711 that restrict the direction of light output.
     10
    According to another aspect of the invention, as can be seen in Figure 2, the photolyte 8 comprises at least a first opaque zone 81 and at least a second transparent zone 82. In this way it is possible to generate by means of the zones that allow the transmission of light (second transparent area 82) an element to be illuminated, which will correspond to the desired logo or image to be highlighted. fifteen

    It should be mentioned that, as seen in Figure 2, the at least one first opaque zone 81 is obtained by an application of a paint on the photolyte 8 and the at least one second transparent zone 82 is obtained by a laser operation to Remove the paint. Another alternative to the laser is to make a negative structure similar to the one used in photography. This allows a very high definition and precision but, on the contrary, it is a higher cost concept.

    According to another aspect of the invention, as seen in Figures 1 and 2, the partially opaque outer cover 9 is of black smoked finish. It is an object of the invention to illuminate a trim so that, when the light emitting assembly is turned off, the existence of a lighting system is not appreciated and the user perceives a trim or outer cover 9 of the same quality and appearance that are currently mounted on a motor vehicle. On the contrary, when the at least one light emitter 4 is in a first on state, the user perceives a trim or molding with an illuminated figure or logo 8.

    More specifically, as seen in Figures 1 and 2, the partially opaque outer cover 9 is made by a bi-injection stage, in which the black smoked finish is injected into an outer face 91 of the structural panel 1. 35

    According to a preferred embodiment of the invention, as seen in Figure 2, the lighting device successively comprises the housing 3, the reflector element 5, the light guide 61 and the photolyte 8, facing the opening 11 of the structural panel 1 and covered by the outer cover 9 partially opaque, the reflector element 5, the light guide 61, the photolyte 8 and the opening 11 being superimposed on each other.

    According to another preferred embodiment of the invention, as seen in Figure 2, the lighting device successively comprises the housing 3, at least one light emitter 4, the photolitho 8 and the polarizing element 71, facing the opening 11 of the structural panel 10 and covered by the outer cover 9 partially opaque, the photolyte 8, the polarizing element 71 and the opening 11 being superimposed on each other.

    According to another preferred embodiment of the invention, as seen in Figure 2, the lighting device successively comprises the housing 3, the reflector element 5, the light guide 61, the photolitho 8 and the polarizing element 71, facing each other. the opening 11 of the structural panel 1 and covered by the partially opaque outer cover 9, the reflector element 5, the light guide 61, the photolyte 8, the polarizing element 71 and the opening 11 being superimposed on each other. It should be mentioned that the sizes of the reflector element 5, of the light guide 61, and of the photolyte 8 are substantially similar. twenty

    The details, shapes, dimensions and other accessory elements, as well as the components used in the implementation of the illumination device for exterior cover of a side of a vehicle may be conveniently replaced by others that are technically equivalent, and do not depart from the essentiality of the invention or of the scope defined by the claims that are included after the following list.
