    ILLUMINABLE COMPONENT WITH A VISIBLE SIDE [0001] The invention relates to an illuminable component with a visible side, an edge that surrounds the visible side and a rear side, comprising a flat decorative element with at least one translucent area and at least one light impermeable area, lighting means to illuminate at least one translucent area and at least one light-conducting layer disposed between a decorative element and the lighting means, which is placed on a rear side of the decorative element.
    [0002] Such components are provided, for example, as door stirrups. They can be placed at the corresponding location in the vehicle body, for example, with coupling means. On the upper or visible side of the component, the translucent area forms, for example, an inscription and / or a symbolic element. Inside the component there are lighting means, for example, a luminous film, LEDs or similar, which illuminate through the transparent light conducting layer through the transparent area. The flat decorative element in this case is, for example, a metal plate that has been molded in a molding matrix by retroinjection with the light-conducting layer. This layer preferably surrounds the entire back side of the decorative element.
    [0003] In the case of such a component the difficulty lies in the fact that in the state mounted on the edge it can occur through a practically unavoidable crack in many cases leakage light which in general is not desired. Such leakage light could be easily avoided by molding a frame made of non-plastic material onto the light-conducting layer.

    2/14 translucent. Thus, for example, in patent document DEC-40 06 649 a switch panel is described in which a transparent plastic is molded next to a flat decorative element. To prevent unwanted light output, a diaphragm body is molded into the decorative element. This plastic material surrounds the transparent plastic in the shape of a frame. Patent document EP-A-0 703 051 describes a component for the manufacture of a key switch. A radiolucent light-conducting plate is molded on the back of a decorative element. This is surrounded by a non-translucent frame, which is molded by injection into the decorative element and the light-conducting plate. Patent document WO 98/49700 describes a diaphragm piece that has a translucent insert, which is injected by a non-translucent material.
    [0004] The components referred to are generally parts in series that need to be manufactured in very high numbers. The requirement for such components is that they can be manufactured at low cost and that they work in a safe manner as well as meeting the high aesthetic requirements. It is mainly essential that the visible side has an attractive surface and that it can avoid light leakage mainly at the edge of the component.
    [0005] It is the task of the present invention to create a component of the type referred to in which leakage light can be largely avoided.
    [0006] The task is solved with a component according to gender, in which means are provided that absorb and / or disperse almost entirely light during the transport of goods.
    Petition 870190074171, of 8/2/2019, p. 12/31
    3/14 means of illumination through at least one light-conducting layer up to said edge. Such means can have, for example, a pigment, which is placed in the light-conducting layer and / or in an adhesion layer and / or in another layer. In this case, the circumstance is explored in which the light path from the lighting medium to the translucent area is shorter than the path to a possible vanishing point at the component's edge. In the relatively long journey to the possible vanishing point, light can be basically absorbed and / or dispersed, for example, through such a pigment, almost entirely. By scattering a leakage light can be avoided almost entirely. The light-absorbing and / or dispersing medium can also be present simply in a partial area of the light-conducting layer and / or in the other layer and / or in the adhesion layer and / or in the decorative element. In the case of the component according to the invention, therefore possible light leakage points can be formed in a larger size than in the case of known components. The invention therefore makes it possible especially to manufacture components with higher manufacturing tolerances since the light in the component is almost completely absorbed and / or scattered before reaching the possible leakage points and, therefore, it is possible to avoid disturbing leakage light. Almost total absorption and / or dispersion can occur if the luminous intensity has been reduced by 90%, the luminous intensity will be at the vanishing point at a maximum of 10% of the luminous intensity present in the illuminated area, measured in cd / m. Preferably, the reduction, however, is greater and is preferably 99%. If in this case, the intensity
    Petition 870190074171, of 8/2/2019, p. 13/31
    4/14 luminous in the illuminated area is 100 cd / m 2 (Candela), so at the vanishing point it will be a maximum of 10 cd / m and preferably a maximum of 1 cd / m.
    [0007] According to an improvement of the invention, the adhesion layer is on the rear side of the decorative element. The adhesion layer and / or the other layer is, for example, an adhesive agent, an adhesive substance or a lacquer. This adhesion layer allows a fixed union of the injected light-conducting layer with the decorative element. Therefore, the decorative element can be completely shaped by retroinjection by the light-conducting layer. The light-conducting layer therefore forms the flat decorative element during the injection molding process. As the decorative element is shaped by retro-injection only by at least one light-conducting layer, an exact conformation and, therefore, an external or visible side of the decorative element, which has the desired shape, can be ensured. The light-conducting layer and the decorative element can therefore be manufactured very easily and precisely as a unit. This unit can be added to the lighting means and, if necessary, to a housing. The component manufactured in this way can be used for the manufacture, for example, of a door step frieze, a frieze, a control element or a button. The decorative element is, for example, a vehicle element, for example, a door step strip, center console, sunroof console, doors, door lining or also a display in the car's interior compartment. It is also possible to form the decorative element as a switch or merely as a switch button. Are
    Petition 870190074171, of 8/2/2019, p. 14/31
    5/14 possible further applications of the invention for illuminable elements, for example for household appliances, for example refrigerators, pressure cookers, automatic washing machines, ovens, kitchen stoves, automatic or mobile dishwashers and the like.
    [0008] According to an improvement of the invention, it is provided that the flat decorative element extends at least partially over said edge. The light-conducting layer, in this case, is preferably formed in such a way that it extends at least into the edge. Preferably, this edge is surrounding. This makes it possible to manufacture a particularly robust and also aesthetically attractive component.
    [0009] The light-absorbing and / or light-scattering means are arranged according to an improvement in the light-conducting layer. These media have, for example, and especially a pigment, which is present homogeneous or non-homogeneous in an injected layer. The pigment is especially suitable for titanium dioxide or cobalt blue or carbon black. According to an alternative embodiment, it is provided that the light-absorbing and / or light-dispersing medium in the adhesion layer and / or in the other layer on the rear side of the decorative element. The adhesion layer and / or the other layer can be arranged on a back side of the decorative element and / or on another part of the component adjacent to the light-conducting layer, such as the surface of a wrapper and / or the material , of which such a component is composed, has light absorbing and / or light dispersing means. The adhesion layer can be formed, for example, by means of an adhesive agent (for
    Petition 870190074171, of 8/2/2019, p. 15/31
    6/14 example, black pigmented heat sealable lacquer), for example, an adhesive substance (for example, black pigmented adhesive substance based on epoxy or polyurethane) or, for example, through a lacquer (for example, black pigmented polyester lacquer). The other layer referred to is, for example, a film (for example, a black polyethylene film), for example, a galvanic black corm coating or a layer made of titanium carbonitrite or titanium oxynitrite.
    [0010] The light absorbing and / or dispersing means may be present in the light-conducting layer and / or in the adhesion layer and / or in another layer and / or in the component's decorative element.
    [0011] In principle, the rear side of the flat decorative element can also be formed as a light absorber. An adhesion layer and / or another layer and / or a decorative element with a light absorber and / or light scatterer and / or in the light-conducting layer are therefore not mandatory. For example, the back side of the decorative element can be formed as a light absorber by chemical modification such as, for example, nitration and, therefore, application of nitrogen.
    [0012] In accordance with an improvement of the invention, a transparent film is provided between the decorative element and the light-conducting layer, which extends at least over the translucent area of the decorative element. This transparent film is preferably free of light-absorbing and / or light-dispersing means. Therefore, it is possible that especially a lot of light reaches the illuminating area through the lighting means. The film
    Petition 870190074171, of 8/2/2019, p. 16/31
    The transparent 7/14 is preferably molded under injection pressure by the light-conducting layer and preferably extends at least partially into at least one passage of the decorative element.
    [0013] In accordance with an improvement of the invention, it is provided that the component has an enclosure, through which it can be fixed on an object, for example on a body or similar. Fixing is done, for example, with coupling elements or the like. The housing is also preferably designed in such a way that it can accommodate the lighting medium. Preferably the casing is designed in such a way that it shields the lighting medium so that the light cannot penetrate behind or from the side. Preferably, the areas adjacent to the light-conducting layer have at least partially preferably a total adhesion layer and / or another layer with light-absorbing and / or light-dispersing means and / or the material, from which the wrapping is made. , has light absorbing and / or light dispersing means.
    [0014] A specially decorative component can be manufactured according to an improvement if the decorative element is made of metal. Preferably, the decorative element is a film or sheet metal, for example, a sheet of metal, especially a sheet of steel or a sheet of steel, a sheet of light metal or a sheet of light metal.
    [0015] Other advantageous features are contained in the dependent claims, the description below as well as the drawing.
    [0016] Examples of embodiments of the invention will be explained in more detail below based on the drawing,
    Petition 870190074171, of 8/2/2019, p. 17/31
    8/14 where:
    [0017] Figure 1 schematically shows a cut through a component according to the invention that is mounted on a piece also cut;
    [0018] Figure 2 shows an enlarged partial section according to figure 1;
    [0019] Figure 3 shows a section according to figure 1, with the flat decorative element being raised with the light-conducting layer molded under injection pressure;
    [0020] Figure 4 shows schematically a section through a component according to the invention assembled according to a
    variant; [0021] THE figure 5 shows schematically a section partial expanded in according to figure 4; and [0022] THE figure 6 shows schematically an View space in a component according to the invention mounted. [0023] O component 1 shown in figures 1 and 2 1 is
    fixed on a rear side 3 on a piece 23, for example, of a bodywork. Component 1 can be glued, for example, to an upper side 25 of part 23 or can also be fixed mechanically with engagement means not shown here. These latching means can be arranged, for example, on the bottom side 3 of a housing 14. Component 1 is, for example, a door step strip, a strip, a control element, for example for a control block or to manufacture a button. It has a front side 2, which forms at least a side side, an edge 4 that surrounds the front side 2, which has an outer side 13. The edge 4 and the outer side 13 are preferably surrounding, which, however It's not mandatory. Front side 2 can be
    Petition 870190074171, of 8/2/2019, p. 18/31
    9/14 plan. However, it is also possible to make an embodiment with a non-flat front side, which has, for example, grooves and / or ribs.
    [0024] The front side 2 and preferably also the outer side 13 of the edge 4 is or are formed by a flat decorative element 5. This is stretched laterally over the edge 4 and extends basically to the upper side 25 of the piece 23. A principle is also possible an embodiment in which the decorative element is stretched laterally not downwards. As shown in figure 2, between a surrounding edge 20 of the flat decorative element 5 and the upper side 25, a gap 21 may be present. This is generally very small, for example, preferably 0.1 to 0.2 mm in size. Preferably, the slot 21 has a size of 0.05 to 1 mm and even more preferably 0.05 to 5 mm. The distance between the edge 20 and the upper side 25 is suggested in figure 2 by means of the double arrow 27. Such a gap 21 can also be produced by a roughness of the piece 23 on the upper surface 25.
    [0025] The decorative element 5 has a translucent area 6, which is illuminable and a non-translucent area 7. Area 6 can, according to figure 6, represent letters for example. In this case, however, other symbolic representations are possible as an example. Area 6 is formed, for example, by indentations of the decorative element 5. Outside area 6, the decorative element 5 is not permeable to light. This is the case, for example, when the decorative element 5 is made of metal, for example, from a steel plate or a light metal plate. In principle, the decorative element 5 could also be made of a material
    Petition 870190074171, of 8/2/2019, p. 19/31
    10/14 non-translucent plastic. The decorative element 5 can also be multilayered.
    [0026] The decorative element 5 has a rear side 8, on which an adhesion layer 11 is placed. This adhesion layer 11 serves especially to attach an injection-molded light-conducting layer 10 to the decorative element 5. The adhesion layer 11 can be, for example, an adhesive, an adhesive or a lacquer. These are preferably pigmented to black. Alternatively, the rear side 8 can be chemically treated. The rear side 8 can, for example, be made absorbent by nitration. It is also possible to apply a layer of black chromium, a film of black polyethylene or a layer made of titanium carbonitrite or titanium oxynitrite. The decorative element 5 is molded by retro-injection by the light-conductive layer 10. During the retro-injection molding of the decorative element 5 with the light-conductive layer 10 the decorative element 5 is molded in the injection molding matrix accordingly. At the same time, the light-conducting layer 10 is joined to the decorative element 5. As we can see, the light-conducting layer extends over the entire back side 8 of the decorative element 5. It forms the translucent area 6 and also the edge 4 as well as according to figure 3 a surrounding front side 19. It further forms according to figure 3 a cavity in the rear side 17 with an inner side 16 preferably flat. This cavity 17 is used to house lighting means 9, which are stored in a housing 14. Lighting means 9 have, for example, a light-conducting layer, in which light is radiated through LEDs
    Petition 870190074171, of 8/2/2019, p. 20/31
    11/14 not shown here. The lighting means 9, however, may present, for example, a luminous film.
    [0027] The light emitted by the lighting means 9 arrives through the light-conducting layer 10 to the translucent area 6 and leaves it, as suggested in figure 2 through light irradiations 28. A part of the light, which is emitted by the lighting means lighting 9, on the other hand, does not come out in the translucent area 6, but is radiated according to the suggested rays 28 'laterally in the light-conducting layer 10. This light could at first arrive through reflection to the gap 21 which would thus form a point of escape. To prevent this from happening, the light-conducting layer 10 contains a medium 24, which absorbs and / or disperses that light. The absorption and / or dispersion action is adjusted in such a way that basically no light can reach the slit 21, so the light is absorbed and / or dispersed in the path to the slit 21 almost completely. The absorption medium and / or dispersion medium 24 is formed, for example, through a pigment that is distributed in the light-conducting layer 10 in a homogeneous or inhomogeneous manner. The absorption medium 24 may at first also be present in the translucent area 6. The path, which the light travels through the illumination medium 9 to the front side 2, is relatively short so that in this case the corresponding absorption and / or dispersion can be dismissed. As it turns out, the path through the lighting means 9 to the slot 21 is a longer multiple of the lighting means 9 to the outside 2. In addition, the escape light would need to change the direction in the area of an edge 26 approximately 90 °.
    [0028] Alternatively or in addition to the
    Petition 870190074171, of 8/2/2019, p. 21/31
    12/14 absorption agent and / or dispersion agent 24 in the light-conducting layer, the adhesion layer 11 can be provided with such an absorption medium and / or dispersion medium. In addition, the housing 14 can also be provided with absorption means. The key is that the light that comes out not in the translucent area 6 on the path towards the slot 21 is absorbed and / or dispersed almost entirely.
    [0029] Figures 4 and 5 show a component Γ, which basically corresponds to component 1, but additionally presents a film 12 made of a translucent plastic material. This film 12 is shaped by retroinjection by the light-conducting layer 10 and extends into holes 29 of the decorative element 5. These holes 29 are, for example, cutouts by punctures. The front side 2 is formed, therefore, by areas through the retro-injection molded film 12. As the film 12 is translucent and preferably does not have absorption means and / or dispersion means, on the way to the translucent area it is absorbed and / or scattered little light. The film 12 is preferably inserted with the decorative element 5 in the injection molding matrix and during retro-injection molding of the light-conducting layer 10 it is plastically deformed. The decorative element 5 needs to be molded by retroinjection, therefore only once to form the light-conducting layer 10. In this case, through the injection pressure the decorative element 5 is molded in the corresponding matrix part. The decorative element molded by retroinjection 5 is placed according to figure 3 in the direction of the arrow 22 on the housing 14, on which the lighting means 9 are deposited. Component 1 is then ready for assembly and can be
    Petition 870190074171, of 8/2/2019, p. 22/31
    13/14 according to figure 6 be fixed on a piece 23. If necessary, the lighting means 9 must be connected using cables not shown here to an electrical power source.
