Description

Fahrzeug mit einer Designbeleuchtung Vehicle with design lighting
TECHNISCHES GEBIET TECHNICAL AREA
Die Erfindung betrifft ein Fahrzeug mit einer Designbeleuchtung nach dem Oberbegriff das Patentanspruchs 1. Insbesondere betrifft die Erfindung ein solches Kraftfahrzeug. The invention relates to a vehicle with design lighting according to the preamble of patent claim 1. In particular, the invention relates to such a motor vehicle.
HINTERGRUND DER ERFINDUNG BACKGROUND OF THE INVENTION
Im Innenraum von vielen Fahrzeugen gibt es eine sogenannte Ambiente- Beleuchtung. Dabei handelt es sich um eine Designbeleuchtung, die zumindest ein beleuchtbares Gestaltungselement aufweist, mit dem beispielsweise Konturlinien oder andere Stil-Elemente des Innenraumdesigns in einer Farbe leuchten, die zumeist vom Fahrzeugnutzer wählbar ist. Das Vorsehen derartiger Elemente zur Designbeleuchtung ist nicht auf den Fahrzeuginnenraum beschränkt, sondern, sofern keine zulassungsrechtlichen Vorschriften entgegenstehen, auch an der Fahrzeugaußenseite möglich. Diese Designbeleuchtung wird durch Leuchtmittel erzeugt, die sowohl nachts als auch tagsüber dauerhaft Licht ausstrahlen. Das ist tagsüber aus energetischer Sicht nicht vorteilhaft, da auch bei Tageslicht elektrische Energie für die Ambiente-Beleuchtung verbraucht wird, was einen verhältnismäßig hohen Energieverbrauch zur Folge hat. Die vorliegende Erfindung soll nun dazu dienen dieses Problem zu beheben oder zumindest zu verbessern. In the interior of many vehicles there is what is known as ambient lighting. This is design lighting that has at least one design element that can be illuminated, with which, for example, contour lines or other stylistic elements of the interior design shine in a color that can usually be selected by the vehicle user. The provision of such elements for design lighting is not limited to the interior of the vehicle, but also possible on the outside of the vehicle, provided there are no legal regulations to the contrary. This design lighting is generated by illuminants that emit light continuously both at night and during the day. From an energy point of view, this is not advantageous during the day, since electrical energy is also used for the ambient lighting during daylight, which results in relatively high energy consumption. The present invention is now intended to remedy or at least improve this problem.
STAND DER TECHNIK STATE OF THE ART
Aus der EP 2 855 206 B1 ist eine individualisierbare Innenraumbeleuchtung eines Fahrzeugs bekannt, die dimmbar ist und die in Abhängigkeit von Umwelteinflüssen oder der Tageszeit ein- und ausschaltbar ist. Die dazu verwendeten Leuchtmittel weisen LED, RGB-LED oder OLED auf. Die Leuchtmittel sind hinsichtlich ihrer Lichtfarbe, Helligkeit, Intensität oder dergleichen einstellbar, wobei jedes Leuchtmittel oder zumindest eine Gruppe von Leuchtmitteln, individuell ansteuerbar ist. Somit können nebeneinander angeordnete LED Unterschiede in ihrer Helligkeit und Farbgebung aufweisen. An individualizable interior lighting of a vehicle is known from EP 2 855 206 B1, which is dimmable and which can be switched on and off depending on environmental influences or the time of day. The illuminants used for this have LEDs, RGB LEDs or OLEDs. The light sources can be adjusted in terms of their light color, brightness, intensity or the like, with each light source or at least one group of light sources being individually controllable. LEDs arranged next to each other can therefore have differences in their brightness and colour.
Aus der DE 10 2011 016 396 A1 sind ein Dekorformteil für den Innenraum eines Fahrzeugs sowie eine Innenraumverkleidung mit einem solchen Dekorformteil bekannt. Das Dekorformteil umfasst eine Beleuchtungseinrichtung, beispielsweise um eine LED oder eine OLED, die dazu ausgebildet ist, den Innenraum des Fahrzeugs über mindestens einen Auskopplungsbereich zu beleuchten. Die Beleuchtungseinrichtung umfasst mindestens eine Lichtquelle zur Erzeugung von Licht und mindestens einen Lichtleiter, der biegesteif ausgebildet ist und in welchen das Licht einkoppelbar ist. Das Licht wird im Auskopplungsbereich flächig ausgekoppelt. Der Lichtleiter kann auf einer oder mehrerer seiner Seitenflächen beschichtet sein, um Effekte bei der Abstrahlung des Lichts im Auskopplungsbereich zu erzielen. Bei der Beschichtung kann es sich um eine Farbbeschichtung und/oder eine Effektbeschichtung handeln, mit der eine Lichtfarbe bestimmt werden kann und/oder das Licht abhängig von dessen Einfallswinkel eingefärbt werden kann. DARSTELLUNG DER ERFINDUNG DE 10 2011 016 396 A1 discloses a molded decorative part for the interior of a vehicle and an interior trim with such a molded decorative part. The decorative molding includes an illumination device, for example an LED or an OLED, which is designed to illuminate the interior of the vehicle via at least one decoupling area. The lighting device comprises at least one light source for generating light and at least one light guide which is designed to be rigid and into which the light can be coupled. The light is decoupled over a large area in the decoupling area. The light guide can be coated on one or more of its side surfaces in order to achieve effects when the light is emitted in the outcoupling area. The coating can be a color coating and/or an effect coating with which a light color can be determined and/or the light can be colored depending on its angle of incidence. PRESENTATION OF THE INVENTION
Aufgabe der vorliegenden Erfindung ist es, ein Fahrzeug mit einer Designbeleuchtung anzugeben, die eine verbesserte Energieeffizienz aufweist. The object of the present invention is to specify a vehicle with design lighting that has improved energy efficiency.
Diese Aufgabe wird gelöst mit den Merkmalen des Patentanspruchs 1 . This problem is solved with the features of patent claim 1 .
Ein Fahrzeug, insbesondere ein Kraftfahrzeug, ist versehen mit einer Designbeleuchtung, die zumindest ein beleuchtbares Gestaltungselement aufweist. Erfindungsgemäß ist dabei vorgesehen, dass das zumindest eine beleuchtbare Gestaltungselement eine E-Paper-Anzeigeeinrichtung aufweist, die durch Anlegen einer elektrischen Spannung zwischen einer schwarzen Einfärbung und einer weißen oder farbigen Einfärbung umschaltbar ist und dass die E-Paper-Anzeigeeinrichtung des zumindest einen beleuchtbaren Gestaltungselements mittels zumindest einer künstlichen Lichtquelle beleuchtbar ist. A vehicle, in particular a motor vehicle, is provided with design lighting that has at least one design element that can be illuminated. According to the invention, it is provided that the at least one illuminable design element has an e-paper display device that can be switched between a black coloring and a white or colored coloring by applying an electrical voltage, and that the e-paper display device of the at least one illuminable design element can be illuminated by means of at least one artificial light source.
VORTEILE BENEFITS
Die Erfindung schlägt vor, anstelle einer bislang üblichen aktiv leuchtenden Ambiente-Beleuchtung zumindest ein beleuchtbares Gestaltungselement mit einer nur bei Bedarf beleuchtbaren E-Paper-Anzeigeeinrichtung vorzusehen. Mittels dieser E-Paper-Anzeigeeinrichtung kann bei Tageslicht der gewünschte Designeffekt, beispielsweise die weiße oder farbliche Betonung einer Kante oder Linie im Fahrzeuginnenraum oder im Bereich der Fahrzeugaußenhaut, ohne künstliche Beleuchtung erzielt werden. Bei Dunkelheit kann dann die künstliche Lichtquelle zur Beleuchtung der E-Paper- Anzeigeeinrichtung eingeschaltet werden. Tagsüber wird so ohne künstliche Beleuchtung und ohne einen damit verbundenen Energieverbrauch der gleiche gestalterische Effekt erzielt. Weitere bevorzugte und vorteilhafte Ausgestaltungsmerkmale des erfindungsgemäßen Fahrzeugs sind Gegenstand der Unteransprüche 2 bis 6. The invention proposes providing at least one illuminable design element with an e-paper display device, which can only be illuminated when required, instead of the actively illuminating ambient lighting that has been customary up to now. Using this e-paper display device, the desired design effect, for example the white or colored emphasis of an edge or line in the vehicle interior or in the area of the vehicle outer skin, can be achieved in daylight without artificial lighting. When it is dark, the artificial light source can then be switched on to illuminate the e-paper display device. During the day, the same design effect is achieved without artificial lighting and without the associated energy consumption. Further preferred and advantageous design features of the vehicle according to the invention are the subject matter of dependent claims 2 to 6.
Vorzugsweise weist das zumindest eine beleuchtbare Gestaltungselement eine Lichtleitereinrichtung aufweist, die das von der zumindest einen Lichtquelle ausgehende Licht entlang der E-Paper-Anzeigeeinrichtung verteilt.

Fig. 1 shows the front part of a vehicle interior 10 of a motor vehicle 1 with a view of the driver's seat 11 with a steering wheel 12 arranged in front of it and the driver-side part of a dashboard 13, and with a view of the left front vehicle door 14 with a door inner panel 15 and on a center console 16, which extends on a center tunnel 17 from the dashboard 13 against the forward driving direction F to the rear.
Der Fahrzeuginnenraum 10 ist mit einer Designbeleuchtung 2 ausgestattet, die eine so genannte Ambientebeleuchtung bildet. Dazu ist die Türinnenverkleidung 15 mit streifenartigen beleuchtbaren Gestaltungselementen 20, 21 , 22 versehen. Die Armaturentafel 13 weist ebenfalls streifenartige beleuchtbare Gestaltungselemente 23 auf. Auch an der Mittelkonsole 16 sind streifenartige beleuchtbare Gestaltungselemente 24, 25 vorgesehen. Weitere streifenartige beleuchtbare Gestaltungselemente 26, 27, 28, 29 sind an der Seite des Mitteltunnels 17 vorgesehen. The vehicle interior 10 is equipped with design lighting 2, which forms what is known as ambient lighting. For this purpose, the door inner lining 15 is provided with strip-like design elements 20, 21, 22 that can be illuminated. The dashboard 13 also has strip-like design elements 23 that can be illuminated. Strip-like design elements 24 , 25 that can be illuminated are also provided on the center console 16 . Additional strip-like design elements 26 , 27 , 28 , 29 that can be illuminated are provided on the side of the central tunnel 17 .
Der Aufbau und die Funktionsweise eines jeden der streifenartigen beleuchtbaren Gestaltungselemente wird anhand der Fig. 2 am Beispiel des dort schematisch dargestellten streifenartigen beleuchtbaren Gestaltungselements 100 beschrieben. The structure and functioning of each of the strip-like, illuminable design elements is described with reference to FIG. 2 using the example of the strip-like, illuminable design element 100 shown schematically there.
Das streifenartige beleuchtbare Gestaltungselement 100 weist einen Trägerkörper 110 auf, in dem eine E-Paper-Anzeigeeinrichtung 120 aufgenommen ist. Die E-Paper-Anzeigeeinrichtung 120 ist versehen mit einem transparenten oder transluzenten Anzeigefenster 122, hinter dem sich eine Vielzahl von als Mikrokapseln ausgestalteten Anzeigeelementen 124 befindet. The strip-like illuminable design element 100 has a carrier body 110 in which an e-paper display device 120 is accommodated. The e-paper display device 120 is provided with a transparent or translucent display window 122, behind which a multiplicity of display elements 124 designed as microcapsules are located.
Wie in Fig. 3 zu erkennen ist, bildet das Anzeigefenster 122 gleichzeitig eine erste flächige (obere) Elektrode 121. Eine zweite flächige (untere) Elektrode 123 ist auf der Rückseite der E-Paper-Anzeigeeinrichtung 120 hinter den Anzeigeelementen 124 vorgesehen. Jedes der Anzeigeelemente 124 weist eine transparente Gehäusewandung 125 auf, die einen Innenraum 126 des Anzeigeelements 124 umschließt. Der Innenraum 126 enthält eine Mehrzahl von ersten Pigmenten 127 einer ersten Farbe (hier weiß) und eine Mehrzahl von zweiten Pigmenten 128 einer zweiten Farbe (hier schwarz), die von einem transparenten Fluid 129 umgeben sind, wobei die schwarzen Pigmente 128 üblicherweise positiv und die weißen Pigmente 127 negativ aufgeladen. Bei Aktivierung eines positiven oder negativen elektrischen Feldes durch Anlegen einer Spannung an die Elektroden 121 , 123 bewegen sich die schwarzen Pigmente 128 und die weißen Pigmente 127 zu den jeweils entgegengesetzten Elektroden 121 , 123. Die Pigmentpartikelmenge, die zur oberen (transparenten) Elektrode 121 wandert, wird für den Betrachter als schwarzer beziehungsweise weißer Punkt im Anzeigefenster 122 sichtbar. Weiterentwicklungen dieser gezeigten E-Paper-Anzeigeeinrichtung 120 mit einer Mehrzahl von unterschiedlichen Anzeigeelementen, die an Stelle der weißen Pigmente 127 farbige Pigmente enthalten besitzen die Fähigkeit, Farben anzuzeigen. As can be seen in FIG. 3, the display window 122 simultaneously forms a first flat (upper) electrode 121. A second flat (lower) electrode 123 is provided on the back of the e-paper display device 120 behind the display elements 124. Each of the display elements 124 has a transparent housing wall 125 which encloses an interior space 126 of the display element 124 . The inner space 126 contains a plurality of first pigments 127 of a first color (white here) and a plurality of second pigments 128 of a second color (here black) surrounded by a transparent fluid 129, the black pigments 128 usually being positively charged and the white pigments 127 being negatively charged. When a positive or negative electric field is activated by applying a voltage to the electrodes 121, 123, the black pigments 128 and the white pigments 127 move to the opposite electrodes 121, 123, respectively. The amount of pigment particles that migrates to the upper (transparent) electrode 121 , is visible to the viewer as a black or white point in the display window 122. Further developments of this shown e-paper display device 120 with a plurality of different display elements that contain colored pigments instead of the white pigments 127 have the ability to display colors.
Der Trägerkörper 110 (Fig. 2) ist weiterhin mit zumindest einer in Fig. 2 nur schematisch dargestellten künstlichen Lichtquelle 3 versehen, die ihr Licht in eine im Trägerkörper 110 ausgebildete Lichtleiteinrichtung 30 abstrahlt. Das von der Lichtquelle 3 abgestrahlte Licht L wird von der Lichtleiteinrichtung 30 über die Fläche des Anzeigefensters 122 verteilt und illuminiert dort die Mehrzahl der von den Mikrokapseln gebildeten Anzeigeelemente 124, deren obere Pigmente 127 daraufhin des Licht durch das Anzeigefenster 122 nach außen reflektieren. Die E-Paper-Anzeigeeinrichtung 120 leuchtet daraufhin in der Farbe der oberen Pigmente 127 (im gezeigten Beispiel in weiß). The carrier body 110 (FIG. 2) is also provided with at least one artificial light source 3, shown only schematically in FIG. The light L emitted by the light source 3 is distributed by the light guide device 30 over the surface of the display window 122 and illuminates there the majority of the display elements 124 formed by the microcapsules, whose upper pigments 127 then reflect the light through the display window 122 to the outside. The e-paper display device 120 then lights up in the color of the upper pigments 127 (in white in the example shown).
Die Elektroden 121 , 123 sind mit einem Beleuchtungs-Steuergerät 4 elektrisch leitend verbunden, das von einer Stromquelle Q mit elektrischer Energie versorgt wird. Das Beleuchtungs-Steuergerät 4 versorgt die Elektroden 121 , 123 mit einem elektrischen Schaltsignal mit entsprechender Polarität, um die Anzeigeelemente 124 zum Beispiel von schwarz auf weiß umzuschalten. Ist die E-Paper-Anzeigeeinrichtung 120 in der Lage, unterschiedliche Farben anzuzeigen, so ist das Beleuchtungs-Steuergerät 4 in der Lage die Anzeigeelemente 124 so zu steuern, dass die E-Paper-Anzeigeeinrichtung 120 eine vom Nutzer gewünschte Farbe anzeigt. The electrodes 121 , 123 are electrically conductively connected to a lighting control device 4 which is supplied with electrical energy from a power source Q . The lighting control device 4 supplies the electrodes 121, 123 with an electrical switching signal with the appropriate polarity in order to switch the display elements 124 from black to white, for example. If the e-paper display device 120 is able to display different colors, the lighting control device 4 is able to To control display elements 124 so that the e-paper display device 120 displays a color desired by the user.
Zudem kann das Beleuchtungs-Steuergerät 4 auch ausgebildet sein, um die Wellenlänge des von der Lichtquelle 3 ausgehenden Lichts und damit dessen Farbe veränderbar einzustellen. In addition, the lighting control device 4 can also be designed to set the wavelength of the light emanating from the light source 3 and thus its color in a variable manner.
Das Beleuchtungs-Steuergerät 4 ist mit einem Helligkeitssensor 40 verbunden, der die Umgebungshelligkeit ermittelt. Aufgrund dieses ermittelten Helligkeitswerts der Umgebungshelligkeit schaltet das Beleuchtungs- Steuergerät die Lichtquelle 3 bei Unterschreiten eines ersten vorgegebenen Helligkeitswerts der Umgebungshelligkeit automatisch ein und beim Überschreiten eines zweiten vorgegebenen Helligkeitswerts der Umgebungshelligkeit automatisch aus. The lighting control device 4 is connected to a brightness sensor 40 which determines the ambient brightness. Based on this determined brightness value of the ambient brightness, the lighting control unit automatically switches the light source 3 on when the ambient brightness falls below a first predetermined brightness value and automatically switches it off when the ambient brightness exceeds a second predetermined brightness value.
Tagsüber wird durch das auf die oberen Pigmente 127 auftreffende und durch das transparente Anzeigefenster 122 einfallende Tageslicht ohne künstliche Beleuchtung der gleiche Effekt erzielt, jedoch ohne Energieverbrauch. During the day, daylight impinging on the top pigments 127 and entering through the transparent display window 122 without artificial lighting achieves the same effect, but without consuming energy.
Durch die hier vorgeschlagene Erfindung wird der Energieverbrauch der Designbeleuchtung 2 am Tag auf null reduziert, da eine künstliche Beleuchtung nur noch bei Dunkelheit erforderlich ist und nicht wie im Stand der Technik durchgehend. Der reduzierte Energieverbrauch beruht dabei auch auf dem Vorteil der E-Paper-Anzeigeeinrichtung 120, nur für den Farbwechsel Energie zu benötigen. Danach bleibt der neue Zustand stromlos stabil. Die erforderliche Energie für den Farbwechsel kann durch das Bordnetz des Fahrzeugs bereitgestellt werden oder auch durch ein - bei einer Anwendung an der Fahrzeugaußenhaut - integriertes Solarpaneel. The invention proposed here reduces the energy consumption of the design lighting 2 to zero during the day, since artificial lighting is only required in the dark and not continuously as in the prior art. The reduced energy consumption is also based on the advantage of the e-paper display device 120 that energy is only required for the color change. After that, the new state remains stable without current. The energy required for the color change can be provided by the vehicle's on-board network or by an integrated solar panel when used on the vehicle's outer skin.
