    Lighting and / or signaling device for a motor vehicle
    The invention relates to a lighting and / or signaling device for a motor vehicle, comprising: - at least two light guides with a Lichteinkoppelstelle and a decoupling, as well as at least one of the respective light guides to parent light source, which light into the respective light guide via the Lichteinkoppelstelle and a subsequent feed line section fed, wherein in the light guides fed light by means arranged in the coupling-out of the respective light guide coupling elements over a light exit area in
    Outcoupling of the respective light guide emerges, and - an at least partially translucent lens, which is arranged in the light exit direction after the light guides.
    Furthermore, the invention relates to a motor vehicle headlight, which comprises at least one illumination and / or signaling device according to the invention.
    Since electric vehicles, especially electrically powered vehicles, are becoming more widespread, information about the state of the remaining electrical energy of such a motor vehicle may be of importance.
    This can be realized with simple means on a dashboard display, with its own lighting and / or signaling device, which can be arranged outside the vehicle, is possible.
    DE 10 2011121 058 A1 describes, among other things, a display about an energy store of a vehicle, which display is shown with light sources of the vehicle, wherein a light function of the vehicle is realized with the same light means, which has no relation to the energy store.
    From DE 10 2007 005 551 Al a lamp is known, said lamp having a housing and a lens, behind which a light source is provided, and wherein the
    Lens is divided into at least two separate translucent and spaced apart light windows having the same or different lighting functions. An at least partially opaque area is present between these light windows, at least one additional transparent area being provided in the light-impermeable area in order to implement a coherent light window required by the legislature if the two light windows fulfill the same light function.
    It is an object of the invention an improved lighting and / or
    Signaling device to provide.
    This object is achieved in that the lens has at least two, at least partially transparent areas separated by an opaque area, called light windows in the further course, which are each associated with at least one of the at least two light guides and their arrangement with respect to the respective light guides an at least partial irradiation of the from the
    Light exit region of the respective light guide exiting light allows.
    A realization of the light windows in the prior art is usually carried out by a continuous, at least partially translucent or transparent lens without opaque areas, with a cover with mostly milled-out light windows of the lens is connected downstream, i. in that the at least partially translucent component or material of the lens is connected to one another in a continuous manner.
    Despite the separate illumination of the individual light windows by respectively associated light sources or light sources, there is inevitably a crosstalk of the emitted light of the light source of a light window into an unassigned light window, since, as mentioned above, the light pane in the prior art consists of a continuous surface, at least partially translucent material or component.
    According to the invention, inter alia, such a crosstalk, so a crosstalk of the light from a light window to an adjacent light window, prevented.
    The number of light windows is determined by the particular design of the device and can be varied or adjusted as desired.
    The shape of the light windows can essentially be directed to the shape of the respective light guides to which the light windows are assigned.
    The light windows can serve the charge level indicator of a motor vehicle, wherein a finer gradation of different states of charge is possible, the more light window has the lens.
    Likewise, the lighting and / or signaling device according to the invention could represent a running light for a turn signal.
    By "at least partially translucent" is meant that the diaphragm surface has a transmittance of less than 1 and thereby regulates the light emerging from the light guide light or attenuates in terms of transmittance - the same applies to "at least partial irradiation".
    Thus, a completely opaque or opaque medium would have a transmittance equal to zero or substantially equal to zero.
    By contrast, media which leave the intensity of the transmitted light unchanged have a transmittance equal to one or substantially equal to one.
    It is advantageously provided if the light guides can be controlled independently of one another.
    This means above all that the light sources, which are assigned to the respective optical fibers, can be controlled independently of one another in order to realize a running light and / or a state of charge display.
    In this case, the light sources can also be dimmable.
    Advantageously, the lens can be produced in one piece in a two-component injection molding process.
    As a result, a real assembly time reduction of the lighting and / or
    Signaling device allows.
    Likewise, a reduction in costs is made possible by the reduction of the individual components. Moreover, in rubbing tests, abrasions were not detected between the light windows and the opaque areas due to the lens produced integrally by the two-component injection molding method.
    In an exemplary embodiment it can be provided that at least one partition wall is arranged between adjacent adjacent light windows, which makes it possible to prevent a crosstalk of a light emitted by a light guide into a light window not assigned to this light guide.
    Furthermore, it may be favorable if at least one separating wall is arranged between the next adjacent light guides in order to prevent crosstalk of emitted light of a light guide into a next adjacent light guide.
    In an expedient embodiment can be provided that the optical fibers are formed as a one-piece optical fiber element, wherein at least one connecting web between the individual optical fibers is designed as a light trap element with at least one decoupling element to a transgression of light fed into a light guide into another optical fiber by means of total optical reflection to prevent.
    It may be advantageous if the optical fibers and the connecting webs are made of a material, preferably produced by means of one-component injection molding.
    This allows a reduction in assembly time and a cost reduction.
    It can be provided that the at least one connecting web is arranged substantially in the region of the respective supply line sections and light coupling points of the light guides.
    In a further embodiment, it is provided that the light guide element is arranged in a support frame, which has recesses for the corresponding light guide of the light guide element, wherein the recesses of the respective light guide of the light guide element irradiation and / or crosstalk of emitted light of a light guide in a next adjacent Prevent light guides.
    It may be advantageous if the respective light windows of the lens extend up to and including the region of the light coupling-in point and of the feed line section of the respective light guide.
    A practice-oriented development of the invention provides that the light windows have a varying wall thickness.
    It may be advantageous if the light windows have a wall thickness profile, wherein the wall thickness decreases in the direction of the light guide end of the respective light guide.
    It may also be favorable if the light windows have a wall thickness profile, wherein the wall thickness increases in the direction of the light guide end of the respective light guide.
    Advantageously, the decoupling elements are formed as prisms in the decoupling section of the respective optical waveguides of the optical waveguide element.
    It can be provided that the decoupling elements have a size and / or spacing profile in the decoupling sections of the respective optical waveguides.
    It is advantageously provided that outcoupling elements are arranged in the feed line section of the respective light guide in order to enable the light emitted by the at least one light source to emerge away from the outcoupling section.
    It is advantageous if the decoupling elements are formed in the lead portion of the respective light guide as a cylindrically shaped grooves.
    It may also be advantageous if the size or the dimensions of
    Decoupling in the supply line section of the respective optical fiber along the respective optical fiber in the direction of the optical fiber end decreases.
    Furthermore, it may be expedient if the at least one light source of the respective light guide is designed as an LED.
    It should be noted that the at least one light source may also comprise a plurality of LEDs, wherein these LEDs may be independently controllable and / or dimmable.
    In an advantageous variant, the device can be a housing with a
    Cover housing cover.
    Advantageously, the light sources are dimmable independently.
    It can be provided that in the area of the light coupling point and the
    Supply line section is arranged a diaphragm component with diaphragm sections, wherein the diaphragm sections are partially transparent and each associated with at least one light guide.
    It may be advantageous if the diaphragm sections has a wall thickness curve in the direction of the light guide end, wherein the wall thickness increases or decreases in the direction of the light guide end.
    For example, it can also be provided that the diaphragm sections have a type of transmittance profile.
    Likewise, it may be favorable if the diaphragm component has at least one partition wall between adjacent diaphragm sections in order to prevent transmission and / or crosstalk of emitted light in the area of the light coupling-in point and of the supply section of a light guide into a next adjacent light guide.
    An objective lighting and / or signaling device can be provided for generating a flashing light distribution or a flashing light function, a low-beam light distribution and / or a charge level indicator of a vehicle, in particular an electric motor vehicle.
    The invention will be explained in more detail with reference to drawings. Hereby shows:

    1 shows an exemplary embodiment of a device according to the invention, comprising five light guides 110, 120, 130, 140, 150, each having a light coupling point 112, 122, 132, 142, 152, an outcoupling section 114, 124, 134, 114, 154, 154 and a light guide end 115, 125, 135, 145, 155 and a light source 111, 121, 131, 141, 515 assigned to the respective light guides 110, 120, 130, 140, 150, which transmit light into the respective light guide 110, 120.130.140.150 via the Lichteinkoppelstelle 112.122,132,142,152 and a subsequent supply line section 113,123,133,143,153 can feed and in the example of FIG. 1 is designed as an LED, the light sources can be independently controlled and / or dimmed, and wherein in the optical fibers 110,120,130, 140.150 fed light by means of decoupling section 114,124,134,144,154 arranged decoupling elements 161 exits via a light exit area.
    The decoupling elements 161 of the decoupling sections 114, 124, 134, 144, 154, 154 extend in the example shown in the figures over the entire decoupling section 114, 124, 134, 114, 154, 154 up to the respective optical fiber end 115, 125, 135, 145, 155, as shown by way of example in FIG. 7 on a light guide 110, wherein one does not extend over the entire decoupling section 115,125,135,145,155 extending arrangement of the decoupling 161 is possible.
    Furthermore, the decoupling elements 161 of the decoupling sections 114, 124, 134, 114, 144, 154 may be formed as prisms, as can be seen in FIG. 8.
    Furthermore, in FIG. 1, in the direction of the light emitted by the light guides 110, 120, 130, 140, 150 - subsequently called light exit direction - downstream lens 200 with five partially opaque areas separated by an opaque area - in the further course of light windows 201, 202, 203, 204 205, which are each assigned to one of the optical waveguides 110, 120, 130, 140, 150, wherein the arrangement of the light windows 201, 202, 203, 204, 205 enables at least partial irradiation of the light emerging from the light exit region of the respective optical waveguides 110, 120, 130, 140, 150 with respect to the respective optical waveguides 110, 120, 130, 140, 150.
    This opaque area closes at a surface configuration of the light window to this area expanding, as the representations of the lens 200 in Fig. 1 and 9 show.
    By "partially translucent" is meant that the light windows 201, 202, 203, 204, 205 have a transmittance of less than 1 in order to attenuate the light emerging from the light guide 110, 120, 130, 140, 150 or from the lead portion 113, 123, 133, 143, 155 as they pass through the respective light windows the light windows 201, 202, 203, 204, 205 preferably from the light guide end 115,125,135,145,155 to Lichteinkoppelstelle 112,122,132,142,152 of the respective optical fiber 110,120,130,140,150 and cover them substantially, ie also the respective Lichteinkoppelstelle 112,122,132,142,152 is of a light window 201, 202, 203, 204, 205th so covered that light from the Lichteinkoppelstelle 112,122,132, 142,152 and the subsequent lead portion 113,123,133,143,153 through the respective light window 201, 202, 203, 204, 205 can at least partially through-beam.
    Furthermore, the lens 200 can be manufactured with the light windows 201, 202, 203, 204, 205 by means of a two-component injection molding process.
    In general, the feed line section of light guides serves to mix the light in order to achieve homogeneous light extraction from the beginning of the coupling-out section or the light exit surface of a light guide, the light emerging from the light guide
    Feed line section is usually not decoupled and therefore usually has no coupling elements. Nevertheless, a perceptible amount of light can escape via the light coupling-in point and / or the lead-in section and influence the light impression of the respective light windows 201, 202, 203, 204, 205, this opposing a homogeneous light impression per light window 201, 202, 203, 204, 205.
    In order to decouple light from the supply line sections 113, 123, 133, 143, 155 and thereby give the individual light windows 201, 202, 203, 204, 205 a more homogenous illumination impression, outcoupling elements 162 can be arranged in the respective supply section 113, 123, 133, 143, 155, as shown in FIGS. 7 and 8.
    Since, in general, the supply line section of a light guide 201, 202, 203, 204, 205 ensures thorough mixing of the light fed in, the outcoupling elements 162 in the supply section 113, 123, 133, 143, 143 of the light guides 110, 120, 130, 140, 150 are designed in such a way that despite the deliberate decoupling of light in the supply section 113, 123, 133, 433, 154 Mixing of the light is not significantly affected, so that the prepared for the decoupling 114,124,134,144,154 in the sense of mixing substantially no significant losses or changes undergoes.
    For this purpose, the decoupling elements 162 of the supply section 113,123,133,143,153 are formed in the form of cylindrical grooves, since such a form has a less strongly directed emission characteristics than a prism usually used for the decoupling of light, which are arranged for example in Auskoppelabschnitt 114,124,134,144,154 of the light guide 110,120,130,140,150, as exemplified in Fig. 7 and 8 shown.
    If the decoupling elements 162 in the supply line section 113,123,133,143,153 are arranged only over a short section along the supply line section 113,123,133,143,153, the distance between the individual output coupling elements 162 and their size or the radius of the cylindrical grooves can be the same.
    In this case, the distance between the individual outcoupling elements 162 of the supply line region can be selected such that it corresponds to the distance between the individual outcoupling elements 161 of the outcoupling section 114, 124, 134, 144, 154, for example the prisms.
    When the light is coupled out over a relatively long section or area of the lead-in section 113, 123, 133, 143, 153, the size and / or the radius of the cylindrical grooves 162 and the depth of the grooves 162 in the lead section 113, 123, 133, 143, 155 can be made to run, the dimensions such as size, Distance between the individual grooves, radius of the cylindrical grooves and / or depth along the light guide 110,120,130,140,150 in the direction of the light guide end 115,125,135,145,155 are designed to increase or decrease. For an improved homogenization of the luminous impression of the individual light windows 201, 202, 203, 204, 205, the light windows may moreover have a non-uniform wall thickness, preferably a wall thickness profile.
    Depending on the shape of the light guides 110, 120, 130, 140, 150 in the region of the light coupling point 112, 122, 132, 142, 152 and the lead section 113, 123, 133, 143, 153 with respect to the desired light exit direction, the wall thickness of the light windows 201, 202, 203, 204, 205 can increase or decrease in the direction of the light guide end 115, 125, 135, 145, 155.
    If the light exit direction of Lichteinkoppelstelle 112.122,132,142,152 in
    As is shown in FIG. 1, it may be advisable to make the wall thickness progression of the light windows 201, 202, 203, 204, 205 decreasing in the direction of the light guide end 115, 125, 135, 145, 155 in parallel to the desired light exit direction of the outcoupling section 114, 124, 134, 144, 154, 154 of the light guides 110, 120, 130, 140, 155.
    In a light exit direction of the light coupling point 112,122,132,142,152, which is substantially orthogonal to the desired light exit direction of Auskoppelabschnitts 114,124,134,144,154 of the light guide 110,120,130,140,150, towards the light guide end 115,125,135,145,155 increasing wall thickness profile of the light windows 201, 202, 203, 204, 205 may be desirable.
    In principle, the wall thickness or the wall thickness profile of the light windows 201, 202, 203, 204, 205 can be matched to the light intensity of the respectively used light guides 110, 120, 130, 140, 150 or the corresponding light sources 111, 121, 131, 141, 51, 51.
    Furthermore, the individual light conductors 110, 120, 130, 140, 150 arranged in an illumination and / or signaling device according to the invention can be embodied as a one-piece optical waveguide element 100, as shown in FIG. 2, wherein at least one connecting web 300 between the individual optical waveguides 110, 120, 130, 140, 150 is designed as a light trap element with at least one outcoupling element 301, in order to prevent a crossing of light coupled into or fed into an optical waveguide 110, 120, 130, 140, 150 into another optical waveguide 110, 120, 130, 140, 150 by means of total optical reflection, wherein preferably the decoupling elements 301 decouple light directly to the front - in the light exit direction.
    The light guides 110, 120, 130, 140, 150 and the connecting webs 300 may be formed of a material, preferably produced by means of one-component injection molding.
    The connecting webs 300 are substantially in the region of the respective
    Lead portions 113,123,133,143,153 and Lichteinkoppelstellen arranged 112.122,132,142,152 the optical fiber 110,120,130,140,150, as shown in Fig. 2.
    A detailed view of two exemplary connecting webs 300 with decoupling elements 310, 311, 312 is shown in FIGS. 3 and 4.
    Among these decoupling elements 310, 311, 312 are defined
    Deflection 311 with associated defined decoupling surfaces 312, and prisms 310, for example in the form of protruding teeth, which in turn may have defined decoupling surfaces.
    Since, in principle, the entire light guide element 100 or the connecting webs 300 contains deflection surfaces and outcoupling surfaces due to the selected material or each surface can serve as a deflection surface or outcoupling surface with respect to a specific light beam at a certain angle, defined deflection surfaces are surfaces which are deliberately arranged to assign the direction of a certain amount of light rays in the direction of a deflection surface defined this
    To lead out or guide outcoupling surface, wherein a defined deflection surface and its associated decoupling surface are arranged such that the deflected, determined amount of light rays orthogonally incident on the decoupling surface to allow an efficient decoupling.
    In Fig. 3, the illustrated, formed as a light trap connecting web 300 no direct connection in the sense of the shortest possible distance between two exemplary optical fibers of the light guide element 100, but is effectively shaped as a bulge.
    Due to this bulged shape, it is possible - in comparison to a direct connection in the above sense - to arrange more decoupling elements 310, 311, 312 and thus to increase the efficiency of the light trap.
    Furthermore, the connecting web 300 or the light trap defined deflection 311 and 311 at least one associated defined decoupling surface 312, wherein the defined deflection 311 and the associated decoupling surface 312 may be inclined 45 degrees to each other, so that light rays in the 45 degree angle the deflecting surface 311 are deflected by 90 degrees and can decouple from the decoupling surface 312, which is associated with this deflecting surface 311 - in the example of FIG. 3 essentially in the light exit direction of the optical fibers 110, 120, 130, 140, 150, which is illustrated by the exemplary, drawn beam paths 701, 703 is shown.
    The defined by such a deflection 311 and its associated
    Decoupling surface 312 uncoupled light beams can be replaced by more
    Moving deflections within the connecting web 300, wherein prisms 310 are arranged for this purpose, for example in the form of protruding teeth as further decoupling elements, as shown in Fig. 3 by an exemplary beam path 702.
    These prisms 310 also have decoupling surfaces, which decouple from
    Allow light rays at an incident angle of substantially 90 degrees.
    For example, different sizes of prisms 310 may be arranged on the connecting web.
    4 shows another example of a connecting web 300, which is designed as a light trap. Here, the connecting web 300 is a direct connection in the sense of the shortest possible connection between two exemplary optical fibers of the light guide element 100, in which case two defined deflection 311 are arranged in the form of notches with respective decoupling surfaces 312. Exemplary beam paths 704, 705 in FIG. 4 illustrate the already mentioned above principle of the deflection surfaces 311 and the associated outcoupling surfaces 312.
    These defined deflection surfaces 311 are arranged such that a direct optical connection between nearest adjacent optical fibers within the connecting web 300 in the sense of a straight light beam is not given.
    It should be pointed out that other shapes of the connecting webs 300 or light traps are also possible, whereby the number and choice of the decoupling elements 310, 311, 312 can also be matched to the geometry of the connecting webs 300.
    Furthermore, at least one separating wall can be arranged between the next adjacent light windows 201, 202, 203, 204, 205, which makes it possible to cross-talk a light emitted by a light guide 110, 120, 130, 140, 150 into a light window 201, 202, 203, 204, 205 not assigned to this light guide to prevent.
    As a result, the homogeneous light impression of the individual light windows 201, 202, 203, 204, 205 can be improved, since only light of the light guide 110, 120, 130, 140, 150 assigned to the respective light window 201, 202, 203, 204, 205 forms the relevant light component for a desired light impression.
    In order to prevent crosstalk of emitted light of a light guide 110,120,130,140,150 in a next adjacent light guide 110,120,130,140,150 and thus also a crosstalk of light of a light guide in a light guide 201, 202, 203, 204, 205, not assigned to this light guide via a next adjacent light guide, can between at least one partition wall to be arranged next adjacent light guides 110,120,130,140,150, wherein the at least one partition both an over talk between adjacent light windows 201, 202, 203, 204, 205 and prevents crosstalk between adjacent light guides.
    Such a partition can be realized by various embodiments, as described in more detail below.
