Description

Beschreibung description
Anzeige mit einer beleuchteten Zierleiste Die Erfindung betrifft eine Anzeige mit einer beleuchteten Zierleiste. Im Stand der Technik sind Anzeigen mit einer in Aufsicht auf die Anzeige zumindest teilweise umgebenden be¬ leuchteten Zierleisten bekannt. Hierbei sind die Zierleisten meist selbst aus lichtleitenden Material ausgestaltet, so dass Lichtstrahlen, welche die Zierleiste verlassen in einem großen Winkelbereich abgestrahlt werden und so gegebenenfalls von in der Nähe der Anzeige vorhandenen reflektierenden Gegenständen reflektiert werden können und so unerwünschte Be¬ leuchtungssituationen entstehen können. The invention relates to a display with a lighted decorative strip. In the prior art displays with the display at least partially surrounding in supervisory be lit ¬ moldings are known. Here, the moldings are usually self-configured from the light conductive material, so that light rays which are the trim left in a large angular range radiated and can thus be reflected from existing in the vicinity of the display reflecting objects if necessary, and so unwanted may arise Be ¬ leuchtungssituationen.
Insbesondere bei Anzeigen, die in Armaturenbrettern von Kraftfahrzeugen eingebaut sind ist es möglich, dass die Lichtstrahlen, die die Zierleisten verlassen, zu der Windschutzscheibe des Kraftfahrzeuges gelangen können und so ins- besondere nachts einen Kraftfahrer durch die Reflexionen irritieren können. Deshalb ist beim Einsatz in Kraftfahrzeugen oft eine Blende vorgesehen, welche die Anzeige zumindest in Richtung der Windschutzscheibe begrenzt und die so verhin¬ dert, dass Lichtstrahlen von der Zierleiste zu Windschutz- scheibe gelangen können. Diese Blenden erfordern zum einen zusätzlichen Bauaufwand und bewirken unter Umständen einen nicht gewünschten unästhetischen Eindruck, der durch die Anzeige mit der Blende erzeugt wird. Aufgabe der Erfindung ist es daher eine Anzeige mit einer beleuchteten Zierleiste an- zugeben, bei der auf eine Blende verzichtet werden kann und die dennoch keine störenden Lichtreflexe von benachbarten reflektierenden Gegenständen verursacht. In particular, in displays that are installed in dashboards of motor vehicles, it is possible that the light rays leaving the moldings can get to the windshield of the motor vehicle and so can irritate a driver in particular by the reflections at night. Therefore, when used in motor vehicles, a diaphragm is often provided, which limits the display of at least in the direction of the windshield and the so verhin ¬ changed that light beams can pass from the trim strip to the windshield. These panels require an additional construction effort and may cause a non-desirable unesthetic impression, which is generated by the display with the panel. The object of the invention is therefore to provide a display with a light-colored trim strip, in which it is possible to dispense with an aperture and yet does not cause disturbing light reflections from adjacent reflective objects.
Diese Aufgabe wird dadurch gelöst, dass die Zierleiste selbst aus opakem Material besteht und einen im Querschnitt derThis object is achieved in that the trim itself consists of opaque material and a cross-section of the
Zierleiste lichtleitenden Kanal zumindest mitbildet, der in Richtung eines Beobachters der Anzeige geöffnet ist und der in der zu dem Beobachter entgegengesetzten Richtung in eine Kammer mit einer Lichtguelle übergeht und so das Licht der Lichtguelle durch den Kanal in Richtung des Beobachters der Anzeige abgestrahlt wird. Durch den Kanal können die Licht- strahlen der Lichtguelle nur in Richtung des Beobachters ge¬ langen, andere Lichtstrahlen werden von den Seitenwänden des Kanals einfach oder mehrfach reflektiert, so dass sie letzt¬ endlich in Richtung des Beobachters abgestrahlt werden, so¬ fern sie den Kanal verlassen. So werden Reflexionen der Lichtstrahlen an Gegenständen in der Nachbarschaft der Anzeige vermieden. Forming strip at least co-forms light-conducting channel, which is open in the direction of an observer of the display and the in the opposite direction to the observer passes into a chamber with a Lichtguelle and so the light of the Lichtguelle is emitted through the channel in the direction of the observer of the display. Through the channel, the light beams of the Lichtguelle can ge ¬ long, other light rays are reflected from the sidewalls of the channel one or more times only in the direction of the observer, so that they will last ¬ finally radiated in the direction of the observer, so ¬ away the Leave channel. Thus, reflections of the light rays at objects in the vicinity of the display are avoided.
Je länger der Kanal im Vergleich zu seiner Breite ist, desto kleiner ist der maximale Winkel zwischen den den Kanal ver- lassenden Lichtstrahlen. Wenn die Breite des Kanals kleiner oder sehr viel kleiner als die Breite der Zierleiste ist, ist der Kanal im nicht beleuchteten Zustand gegebenenfalls schlecht bis nicht wahrnehmbar und wird nur dann wahrgenommen, wenn Lichtstrahlen den Kanal verlassen. Da die Zierleis- te aus opakem Material besteht oder mit opakem Material be¬ schichtet ist, kann sie selbst kein Licht aussenden. So wird ebenso sichergestellt, dass das Licht nur in Richtung eines Beobachters der Anzeige abgestrahlt wird. Wenn innerhalb des Kanals eine Blende angeordnet ist, kann gegebenenfalls der maximale Winkel zwischen den aus dem Kanal austretenden Lichtstrahlen weiter reduziert werden. The longer the channel is compared to its width, the smaller the maximum angle between the light rays leaving the channel. If the width of the channel is smaller or much smaller than the width of the trim strip, the channel in the non-illuminated state is possibly bad to imperceptible and is perceived only when light rays leave the channel. Since the Zierleis- te of opaque material or be ¬ overcoated with opaque material, they can not emit light itself. This also ensures that the light is emitted only in the direction of an observer of the display. If an aperture is disposed within the channel, the maximum angle between the light rays exiting the channel may be further reduced, if necessary.
Dadurch, dass die Anzeige für ein Kraftfahrzeug bestimmt ist, wobei das Kraftfahrzeug eine Windschutzscheibe aufweist und der maximale Winkel, der zwischen den aus dem Kanal austre¬ tenden Lichtstrahlen auftreten kann, so gewählt ist, dass keiner der Lichtstrahlen direkt zu der Windschutzscheibe des Kraftfahrzeuges gelangen kann, wird zuverlässig verhindert, dass Reflexionen durch Lichtstrahlen verursacht werden, die von der beleuchteten Zierleiste herrühren. So kann auf eine zusätzliche Blende zwischen der beleuchteten Zierleiste und der Windschutzscheibe verzichtet werden. Somit ist die Aus¬ wahl des auszuwählenden Designs der Anzeige aus lichttechnischen Gründen nicht eingeschränkt. Die Zierleiste selbst kann im Querschnitt eine rechteckförmi- ge oder ovale Kontur aufweisen. Hierdurch sind unterschiedliche Designeffekte realisierbar. Characterized in that the display is intended for a motor vehicle, wherein the motor vehicle has a windshield and the maximum angle that can occur between the austre ¬ border from the channel light rays, is selected so that none of the light rays reach directly to the windshield of the motor vehicle can reliably prevents reflections are caused by light rays, which originate from the illuminated trim strip. So can on an additional aperture between the illuminated trim and be dispensed with the windshield. Thus, the off ¬ choice of designs to be selected the display of light-technical reasons is not restricted. The trim strip itself can have a rectangular or oval contour in cross section. As a result, different design effects can be realized.
Wenn die Zierleiste im Querschnitt eine winkelförmige Kontur aufweist, kann dieser Winkel insbesondere im Bereich des Win¬ kels in die Kammer übergehen und diese mit bilden. When the trim strip has an angular contour in cross-section, this angle may in particular proceed in the range of Win ¬ kels into the chamber and form these with.
Wenn die Zierleiste im Querschnitt eine U-förmige Kontur auf¬ weist, kann der" Boden" des U gleichzeitig die Kammer bilden. Es ist aber darauf zu achten, dass die Schenkel des U hinrei¬ chend lang sind, damit die den Kanal verlassenden Lichtstrahlen nur in Richtung eines Beobachters der Anzeige gelangen. When the trim strip in cross section has a U-shaped contour ¬, the "floor" of the U can form the chamber simultaneously. However, it is important to ensure that the legs of the U are rea ¬ accordingly long, so that the channel exiting light rays pass only in the direction of an observer of the display.
Wenn die Kammer sich im Querschnitt gegenüber dem Kanal er- weitert, kann der Kanal selbst relativ kurz ausgestaltet sein und dennoch die Lichtstrahlen nur in Richtung eines Beobachters der Anzeige passieren lassen. If the chamber widens in cross-section with respect to the channel, the channel itself may be made relatively short and still allow the light rays to pass only in the direction of an observer of the display.
Wenn die Lichtguelle einen Lichtleiter aufweist, in den Licht einer lichterzeugenden Vorrichtung einkoppelbar ist und dasIf the Lichtguelle has a light guide can be coupled into the light of a light-generating device and the
Licht aus dem Lichtleiter in Richtung der Kammer und/oder des Kanals auskoppelbar ist, wird minimal nur eine lichterzeugende Vorrichtung benötigt und weiterhin kann das Licht durch eine entsprechende Gestaltung des Lichtleiters gleichmäßig verteilt werden, so dass die den Kanal verlassenden Licht¬ strahlen gleichmäßig entlang der Zierleiste verteilt sind. Light can be coupled out of the light guide in the direction of the chamber and / or the channel, only a light-generating device is minimally required and furthermore the light can be evenly distributed by a corresponding design of the light guide so that the light rays leaving the channel are uniformly distributed along the light path Trim are distributed.
Die lichterzeugende Vorrichtung weist vorteilhafter Weise ei¬ ne Leuchtdiode auf oder ist vorteilhafter Weise als Leuchtdi- ode ausgestaltet. Hierdurch kann eine dauerhafte Lichtguelle realisiert werden, die wenig Energie verbraucht und wenig Ab¬ wärme entwickelt. Es sind aber auch andere bekannte oder zu- künftig noch zu entwickelnde Lichtguellen denkbar, beispiels¬ weise Glühlampen oder Leuchtstofflampen. The light generating device comprises advantageously ei ¬ ne light emitting diode or is advantageously configured as a light emitting diode. This makes it possible to realize a permanent Lichtguelle that consumes little energy and little developed from ¬ heat. But there are also other known or in the future still to be developed Lichtguellen conceivable example ¬ incandescent or fluorescent lamps.
Wenn der Lichtleiter Aufrauhungen aufweist, in die das Licht der lichterzeugenden Vorrichtung einkoppelbar ist, kann insbesondere das Licht einer oder mehrerer Leuchtdioden gleichmäßiger verteilt werden, so dass eine gleichmäßige Verteilung der den Kanal verlassenden Lichtstrahlen erreicht werden kann. Es ist auch möglich, eine Vielzahl von einzelnen Licht- guellen, beispielsweise Leuchtdioden für die Beleuchtung vorzusehen, ohne einen Lichtleiter zu verwenden, wenn der Kanal oder die Kammer entsprechend ausgebildet ist oder wenn eine ungleichmäßige Beleuchtung der Zierleiste aus designtechni¬ schen Gründen gewünscht wird. In particular, if the optical waveguide has roughnesses into which the light of the light-generating device can be coupled in, the light of one or more light-emitting diodes can be distributed more uniformly, so that a uniform distribution of the light beams leaving the channel can be achieved. It is also possible, Guellen a plurality of individual light to provide for example, light emitting diodes for illumination without using a light guide, if the channel or chamber is formed according to, or when a non-uniform illumination of the trim strip from designtechni ¬ reasons, is desired.

In Figur 1 erkennt man einen Teil eines Armaturenbretts 100 und ein Ausführungsbeispiel einer erfindungsgemäßen AnzeigeFIG. 1 shows a part of a dashboard 100 and an embodiment of a display according to the invention
101. Von der Anzeige 101 erkennt man einen Anzeigebereich101. From the display 101 can be seen a display area
102, eine Zierleiste 103 und eine Öffnung 104 eines ansonsten nicht dargestellten Kanals. Der Anzeigebereich 102 wird dem dargestellten Ausführungsbeispiel von der Öffnung 104 des Kanals und der Zierleiste 103 vollständig umgeben. Es ist aber auch möglich, die Zierleiste 103 und die Öffnung 104 des Ka- nals den Anzeigebereich 102 nur teilweise umgeben zu lassen. Die Öffnung 104 des Kanals ist in Figur 1 wesentlich größer dargestellt, als man sie in der Realität vorsehen würde. Die tatsächliche Breite BB der Öffnung des Kanals kann weniger als 1 mm bis wenige Millimeter betragen. Besonders wenn die Breite sehr klein ist kann die Öffnung des Kanals 104 im unbeleuchteten Zustand schlecht bis nicht wahrgenommen werden und wird erst durch die Beleuchtung wahrnehmbar. Der Anzeigebereich 102 kann reale Rundinstrumente 105 aufweisen, zwischen denen eine elektrooptische Anzeige 106 angeordnet ist. Es ist aber auch möglich, auf die elektrooptische Anzeige 106 vollständig zu verzichten oder den Anzeigebereich 102 vollständig als eine einzige elektrooptische Anzeige auszugestal¬ ten und auf dieser elektrooptischen Anzeige Rundinstrumente und sonstige Informationen und Anzeigen darzustellen. 102, a trim 103 and an opening 104 of an otherwise not shown channels. The display region 102 is completely surrounded by the opening 104 of the channel and the trim strip 103 in the illustrated embodiment. However, it is also possible for the trim strip 103 and the opening 104 of the channel to only partially surround the display area 102. The opening 104 of the channel is shown in Figure 1 is substantially larger than they would provide in reality. The actual width BB of the opening of the channel may be less than 1 mm to a few millimeters. Especially when the width is very small, the opening of the channel 104 in the unlit condition can be bad to not perceived and is only noticeable by the lighting. The display area 102 may include real round instruments 105, between which an electro-optical display 106 is disposed. But it is also possible to dispense entirely with the electro-optical display 106 or 102 fully represent the display area as a single electro-optical display auszugestal ¬ th and on this electro-optical display round dials and other information displays.
In Figur 2 erkennt man den Schnitt AA aus Figur 1 und ein Auge E eines ansonsten nicht dargestellten Beobachters der Anzeige 101. Das Auge E ist nur symbolhaft und im Verhältnis zur Anzeige 101 stark vergrößert und in zu kleinen Abstand zur Anzeige 101 dargestellt. Die Anzeige 101 weist den Anzei¬ gebereich 102, die Zierleiste 103 die Öffnung 104 eines Ka¬ nals 113, einen Zeiger 106 und ein Zifferblatt 107 des Anzei¬ gebereichs 102, eine Leiterplatte 108, ein Messwerk 109, ein Gehäuse 110 des Anzeigebereichs 102, SideLEDs 111, einen Lichtleiter 112, eine Kammer 114, ein Deckglas 115 des Anzeigebereichs 102 und ein Außengehäuse 116 auf. Der Kanal 113 wird von den Wänden der Zierleiste 103 und des Gehäuses 110 des Anzeigebereichs 102 gebildet. Er geht in die Kammer 114 über, die sich bis hinter das Gehäuse 110 des Anzeigebereichs 102 erstreckt. Auf der dem Betrachter zugewandten Seite weist der Kanal 113 die Öffnung 104 auf. Die SideLEDs 111 sind auf der Leiterplatte 108 der Art angeordnet, dass sie Licht, wel- ches sie aussenden in den Lichtleiter 112 einkoppeln. In Figur 2 sind zwei SideLEDs 111 dargestellt. Es sind aber auch mehr SideLEDs 111 möglich. Bei entsprechender Ausgestaltung des Lichtleiters 112 und einer entsprechenden Leistung der SideLED 111 kann auch eine einzige SideLED 111 ausreichend sein. Das in den Lichtleiter 112 ein gekoppelte Licht wird vom Lichtleiter in den Kanal 113 eingekoppelt, so dass ausge¬ koppelte Lichtstrahlen L entweder direkt zur Öffnung 104 des Kanals 113 gelangen oder einfach oder mehrfach von den Wänden der Zierleiste 103 und oder den Wänden des Gehäuses 110 re¬ flektiert werden und so letztendlich ebenfalls zur Öffnung 104 des Kanals 113 gelangen und sich in Richtung des Beobachters bewegen. Die Lichtstrahlen L sind der Übersichtlichkeit halber nur für den oberen Kanal 113 dargestellt. Um den maxi- malen Winkel, der zwischen den austretenden Lichtstrahlen entstehen kann, möglichst klein zu gestalten, kann zum einen der Kanal 113 möglichst schmal gestaltet werden, oder aber es kann an der Öffnung 104 des Kanals 113 oder im Verlauf des Kanals 113 eine zusätzliche nicht dargestellte Blende ange- ordnet sein, die nur Strahlen passieren lässt, die sich inFIG. 2 shows the section AA from FIG. 1 and an eye E of an observer of the display 101, which is not otherwise shown. The eye E is only symbolically enlarged and in relation to the display 101 and is shown too small a distance from the display 101. The display 101 has the Ad ¬ give reaching 102, the molding 103, the opening 104 of a Ka ¬ Nals 113, a pointer 106 and a dial 107 of the Ad ¬ give realm 102, a circuit board 108, a measuring unit 109, a housing 110 of the display area 102, SideLEDs 111, a light guide 112, a chamber 114, a cover glass 115 of the display area 102 and an outer housing 116 on. The channel 113 is formed by the walls of the trim strip 103 and the housing 110 of the display area 102. It enters the chamber 114, which extends beyond the housing 110 of the display area 102. On the side facing the observer, the channel 113 has the opening 104. The SideLEDs 111 are arranged on the printed circuit board 108 of the type that they light, Wel- Insert it into the light guide 112. FIG. 2 shows two side LEDs 111. But there are also more SideLEDs 111 possible. With a corresponding configuration of the light guide 112 and a corresponding power of the side LED 111, a single side LED 111 may be sufficient. The coupled into the light guide 112 a light is coupled from the light guide into the channel 113 so that out ¬ coupled light rays L either go directly to the opening 104 of the channel 113 or simply or multiple times from the walls of the trim strip 103 and or the walls of the housing 110th re ¬ be inflected and so ultimately reach the opening 104 of the channel 113 and move in the direction of the observer. The light beams L are shown for clarity only for the upper channel 113. In order to make the maximum angle that can arise between the exiting light beams as small as possible, on the one hand, the channel 113 can be made as narrow as possible, or it can at the opening 104 of the channel 113 or in the course of the channel 113 an additional not shown, which only lets rays that are in
Richtung des Beobachters der Anzeige 101 bewegen. In Figur 2 ist die Zierleiste 103 winkelförmig ausgestaltet und bildet so auch eine Begrenzung der Kammer 114. Die SideLEDs 111 sind auf der Leiterplatte 108 angeordnet und werden so mit Strom versorgt. Das Messwerk 109 ist ebenfalls auf der Leiterplatte angeordnet und treibt den Zeiger 106 an. In Figur 2 befindet sich das Deckglas 115 in einer Ebene mit dem Ende der Zier¬ leiste 103. Es ist aber auch möglich, die Zierleiste über die Ebene des Deckglases 115 überstehen zu lassen, oder aber das Ende der Zierleiste unterhalb der Ebene des Deckglases 115 anzuordnen. Wenn das Ende der Zierleiste 103 die Ebene Deck¬ glases 115 überragt, ist sie besonders gut wahrnehmbar. Die Zierleiste kann aus opakem Material hergestellt sein oder aber mit einem opakem Material beschichtet sein, beispiels- weise einem opakem Lack oder einem Metall, insbesondereMove the observer's direction of the display 101. In Figure 2, the trim strip 103 is angularly configured and thus also forms a boundary of the chamber 114. The side LEDs 111 are arranged on the circuit board 108 and are thus supplied with power. The measuring mechanism 109 is also arranged on the circuit board and drives the pointer 106 at. In Figure 2, the cover glass 115 is in a plane with the end of the trim ¬ bar 103. It is also possible to let the trim over the plane of the cover glass 115, or the end of the trim strip below the plane of the cover glass 115th to arrange. If the end of the trim strip 103 projects beyond the plane of the cover glass ¬ 115, it is particularly noticeable. The trim strip can be made of opaque material or coated with an opaque material, for example an opaque lacquer or a metal, in particular
Chrom. Die Zierleiste 103 ist im dargestellten Ausführungs¬ beispiel mit dem Außengehäuse 116 verbunden und bildet so ei- nen Teil des Außengehäuses der erfindungsgemäßen Anzeige mit. Es ist aber auch möglich, die Zierleiste entfernt vom Außen¬ gehäuse der Anzeige vorzusehen. In Figur 3 weist das Ausführungsbeispiel der Zierleiste 103 im Querschnitt eine U-Form auf. So wird im unteren Bereich des U die Kammer 114 gebildet, in der der Lichtleiter 112 angeordnet ist. Schenkel 1030 der Zierleiste 103 bilden den Ka¬ nal 113. Die Schenkel 1030 müssen entweder im Verhältnis zu ihrem gegenseitigen Abstand relativ lang sein, oder aber es sollte noch eine Blende zwischen den Schenkeln 1030 im Kanal 113 vorhanden sein, um die Lichtstrahlen nur in Richtung des Beobachters gelangen zu lassen. In Figur 4 ist die Zierleiste 103 im Querschnitt rechteckför- mig ausgestaltet und mit dem Außengehäuse 116 verbunden. Die Kammer 114 befindet sich auch teilweise hinter dem Anzeigebe¬ reich 102 der Anzeige, der Kanal 113 wird von der Zierleiste und dem Rand des Anzeigebereichs 102 gebildet. Chrome. The trim strip 103 is in the illustrated embodiment ¬ example connected to the outer housing 116 and thus forms a NEN part of the outer housing of the display according to the invention. But it is also possible to provide the trim strip away from the outer ¬ housing the display. In Figure 3, the embodiment of the trim strip 103 in cross-section on a U-shape. Thus, in the lower region of the U, the chamber 114 is formed, in which the light guide 112 is arranged. Leg 1030 of the trim strip 103 form the Ka ¬ channel 113. The legs 1030 must either be relatively long in relation to their mutual distance, or it should still be a diaphragm between the legs 1030 in the channel 113 to the light rays only in the direction Obtain the observer. In FIG. 4, the decorative strip 103 has a rectangular cross-section and is connected to the outer housing 116. The chamber 114 is also partially behind the Anzeigeebe ¬ rich 102 of the display, the channel 113 is formed by the trim strip and the edge of the display area 102.
Das Ausführungsbeispiel in Figur 5 unterscheidet sich von dem Aus führungsbeispiel in Figur 4 nur dadurch dass die Zierleis¬ te im Querschnitt statt der rechteckigen Form eine ovale Form aufweist . Der Querschnitt der Zierleiste kann auch so gewählt werden, dass er grundsätzlich eine rechteckige Form aufweist, wobei sein dem Beobachter der Anzeige zugewandtes Ende abge¬ flacht oder abgerundet ist. The embodiment in Figure 5 differs from the imple mentation example in Figure 4 only in that the Zierleis ¬ te has an oval shape in cross section instead of the rectangular shape. The cross section of the trim strip can also be chosen so that it basically has a rectangular shape, wherein its the observer of the display facing end abge ¬ flattened or rounded.
