Definitions
- the invention relates to a display device for presenting visual content, which has a plurality of light sources and a controller for driving the individual light sources, the light sources being arranged in a matrix consisting of a number of columns and a number of rows.
- Display devices known from practice generally consist of a number of modules or panels, each of which has a fixed frame, with a number of modules or panels being arranged one above the other and next to one another in order to achieve the desired screen size. Due to the use of individual rigid modules, the construction of the display device and the transport of the individual modules is relatively expensive, also because of their relatively high weight. This applies in particular when the display device is to have relatively large dimensions in order to be able to be used, for example, at sports or entertainment events outdoors or in halls in front of a large number of spectators.
- a display device in which a plurality of tubular lighting devices, which consist of transparent tubes and printed circuit boards arranged in their center with lighting means arranged thereon, are held in a rectangular frame by clamping devices, so that the individual lighting devices can be connected to the frame in a simple manner.
- the control is also attached to the frame using clamping devices.
- several of the individual box-shaped modules have to be assembled, which in turn is associated with a relatively large assembly outlay.
- the EP 1 892 691 B1 discloses a display device with a plurality of LEDs, the size and outer contour of which should be changeable in a simple manner in that the individual rigid, elongated support elements on which the LEDs are arranged are connected to one another only via a horizontally running support rail.
- This known display device therefore does not have a rigid, rectangular frame, so that carrier elements of different lengths can be used.
- the carrier elements are in turn circular tubes that hold the individual, vertical completely enclose the LED elements arranged one above the other, which should protect them from the weather.
- the object of the present invention is to provide a display device which is characterized by the simplest possible construction and transport.
- the display device should preferably also be able to be adapted as simply as possible to different conditions of use.
- the display device has a plurality of flexible carrier elements which are arranged at a distance next to one another and each have a plurality of light sources.
- the display device has two holding elements, between which the individual support elements are stretched, and a controller for controlling the individual light sources.
- the lamps of the individual carrier elements are arranged in at least two columns next to one another and in several rows one below the other, the vertical distance a between two adjacent lamps in a column corresponding to the horizontal distance b between two adjacent lamps in a row.
- the distance c between adjacent support elements is chosen such that the horizontal distance between two adjacent light sources of two adjacent support elements corresponds to the horizontal distance b between two adjacent light sources of one support element.
- both the vertical distance a and the horizontal distance b between adjacent lamps are the same, so that the display device can generate a uniform, homogeneous and stripe-free image.
- the number of lamps in a column is usually much larger than the number of lamps in a row.
- approximately 20 to 65 lamps can be arranged one below the other in a column, depending on the distance between the lamps and the diameter of the individual lamps.
- the display device according to the invention consists neither of several rectangular, rigid modules, nor does it have a rigid, closed holding frame.
- the individual light sources which are in particular LEDs, are also not arranged on a rigid carrier element or surrounded by a rigid tube.
- the display device according to the invention is constructed from a plurality of flexible, strip-shaped carrier elements which are each arranged next to one another at a predetermined distance, the individual carrier elements being fastened with their two ends in the two holding elements.
- the display device can be attached with its first, upper holding element, for example, to a scaffolding, a wall or a crane.
- the display device according to the invention does not have any rigid modules, but several flexible carrier elements, the display device has a significantly lower weight in comparison to known display devices made up of individual modules.
- the weight saving compared to conventional modules or panels can be more than 50%.
- the use of flexible support elements, which can be folded or rolled up before assembly, also results in a considerable saving of space during transport.
- the display device according to the invention also saves a considerable amount of time during assembly, since the individual flexible support elements lying on the floor can be connected to the two holding elements and then the display device can be pulled up on the first, upper holding element, similar to a screen or a curtain can be, for example, using a crane or mounted on a traverse using a traverse lift.
- a further advantage of the display device according to the invention is that because the individual support elements are arranged at a distance from one another, there are slot-shaped free spaces between the individual support elements, so that the mounted display device is significantly less susceptible to wind than conventional, rigid display devices, since the wind blows through can pass through the spaces.
- the significantly reduced weight of the display device also reduces the risk of injury should a display device nevertheless fall over.
- the individual flexible carrier elements consist at least partially of a plastic material, in particular of a thermoplastic plastic material, for example of polyethylene, polycarbonate or polyamide.
- a rubber or a silicone can also be used in whole or in part for the material of the carrier elements.
- the choice of plastic, rubber or silicone for the material of the support elements has the advantage that the support elements with the lamps arranged therein can be easily produced, the flexibility of the support elements being able to be adjusted depending on the length and the width of the support elements. The greatest possible flexibility is advantageous so that the carrier elements can be stowed away in a space-saving manner during transport.
- the support elements must not be so flexible or elastic that the individual support elements move too much in the installed state in the wind, since this would adversely affect the image quality of the display device.
- At least one, preferably two, metal cables, in particular one or two steel cables, are integrated in each of the individual flexible support elements.
- the at least one cable extends essentially over the entire length of the flexible support elements, so that the two ends of the individual cables are each arranged in the region of the two ends of the individual flexible support elements.
- the ends of the ropes preferably have a fixing element, for example an eyelet or a loop, so that the ropes can also be used to brace the support elements.
- recesses are formed in the ends of the flexible support elements corresponding to the fixation elements on the ropes, so that the ropes and thus also the support elements can be fastened in the two holding elements using corresponding fastening elements, for example screws or fastening pins.
- the individual flexible support elements are preferably suspended with their first end on the first holding element and are each received with their second end in the second holding element in such a way that the flexible support elements are clamped between the first holding element and the second holding element can become.
- Corresponding clamping elements are provided for this purpose on the second holding element intended for tensioning the flexible support elements.
- connection elements for the electrical connection of the individual illuminants of a carrier element to the controller are preferably provided at the first end or at the second end of the individual flexible carrier elements.
- plug-in contacts can be provided as connection elements, for which the controller then has corresponding mating plug-in contacts.
- the electrical connection between the individual flexible carrier elements or the lighting means arranged therein and connected via lines and the controller can also be made via sliding contacts or spring contacts.
- the sliding contacts or spring contacts are preferably provided on the controller and make contact with corresponding contact surfaces on the ends of the carrier elements when the carrier elements are connected to the holding elements.
- the 1 and 3 12 show two different exemplary embodiments of a display device 1 according to the invention, which differ from one another essentially only in terms of their size, in particular their width.

- eight carrier elements 2 are held by a first holding element 4a and a second holding element 4b or are stretched between a first holding element 4a and a second holding element 4b.
- a different number of carrier elements 2 can also be clamped between a first holding element 4a and a second holding element 4b.
- the individual carrier elements 2 each have a plurality of light sources 3 which are arranged in at least two columns next to one another and in several rows one below the other.
- three columns or four columns of lighting means 3 can also be arranged next to one another on a carrier element 2 .
- the number of illuminants arranged one below the other in a column ie the number of rows of illuminants 3 arranged next to one another, is significantly greater than the number of columns.
- each carrier element 74 has illuminants 3 which are arranged in two columns next to one another and in a total of 38 rows one below the other.
- the number of lamps 3 or the number of those arranged one below the other rows depends in particular on the length of the flexible carrier elements 2 .
- the vertical distance a between two adjacent lamps 3 in a column corresponds to the horizontal distance b between two adjacent lamps 3 in a row.
- the distance c between adjacent support elements 2 is chosen such that the horizontal distance between two adjacent light sources 3 of two adjacent support elements 2 corresponds to the horizontal distance b of two adjacent light sources 3 in a row of a support element 2 .

- controller 5 consists of several control units 5a, 5b, these are electrically connected to one another via a cable 6, the cable 6 also being arranged on the back of the first holding elements 4a and thus on the back of the display device 1, as shown in FIG 3 is evident.
- figure 5 shows an enlarged section of the display device 1 according to FIG 3 from the back.
- the dashed lines in the individual support elements 2 indicate that two steel cables 7 are integrated in the individual support elements 2 and extend essentially over the entire length of the support elements 2 .

- corresponding fastening elements for example screws or fastening pins
- the flexible carrier elements 2 have a high torsional rigidity , even if the carrier elements 2 consist of a plastic material, a rubber or a silicone.
- the arrangement of the steel cables 7 in the support elements 2 also improves the possibility of tensioning the individual support elements 2 between the two holding elements 4a and 4b, so that the support elements 2 are sufficiently taut in the fully assembled state of the display device 1 and are therefore not sag can. This also improves the quality of the images displayed on the display device 1 .
- a suspension 10 is attached to the first holding element 4a, which is used to fasten the display device 1 .
- the suspension 10 can also be used to pull up the display device 1, which was previously lying on the floor during assembly.

Description
Die Erfindung betrifft eine Anzeigevorrichtung zur Präsentation von optischen Inhalten, die eine Mehrzahl von Leuchtmitteln und eine Steuerung zur Ansteuerung der einzelnen Leuchtmittel aufweist, wobei die Leuchtmittel in einer Matrix bestehend aus mehreren Spalten und mehreren Reihen angeordnet sind.The invention relates to a display device for presenting visual content, which has a plurality of light sources and a controller for driving the individual light sources, the light sources being arranged in a matrix consisting of a number of columns and a number of rows.
Aus der Praxis bekannte Anzeigevorrichtungen bestehen in der Regel aus mehreren Modulen bzw. Panels, die jeweils einen festen Rahmen aufweisen, wobei mehrere Module bzw. Panels übereinander und nebeneinander angeordnet werden, um die gewünschte Bildschirmgröße zu realisieren. Durch die Verwendung einzelner starrer Module ist der Aufbau der Anzeigevorrichtung und der Transport der einzelnen Module, auch aufgrund ihres relativ hohen Gewichtes, relativ aufwendig. Dies gilt insbesondere dann, wenn die Anzeigevorrichtung relativ große Abmessungen aufweisen soll, um beispielsweise bei Sport- oder Unterhaltungsveranstaltungen im Freien oder in Hallen vor einer großen Anzahl von Zuschauern eingesetzt werden zu können.Display devices known from practice generally consist of a number of modules or panels, each of which has a fixed frame, with a number of modules or panels being arranged one above the other and next to one another in order to achieve the desired screen size. Due to the use of individual rigid modules, the construction of the display device and the transport of the individual modules is relatively expensive, also because of their relatively high weight. This applies in particular when the display device is to have relatively large dimensions in order to be able to be used, for example, at sports or entertainment events outdoors or in halls in front of a large number of spectators.
Aus der
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Anzeigevorrichtung zur Verfügung zu stellen, die sich durch einen möglichst einfachen Aufbau und Transport auszeichnet. Vorzugsweise soll die Anzeigevorrichtung darüber hinaus auch möglichst einfach an unterschiedliche Einsatzbedingungen angepasst werden können.The object of the present invention is to provide a display device which is characterized by the simplest possible construction and transport. In addition, the display device should preferably also be able to be adapted as simply as possible to different conditions of use.
Diese Aufgabe ist durch eine Anzeigevorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Die erfindungsgemäße Anzeigevorrichtung weist mehrere flexible Trägerelemente auf, die mit Abstand nebeneinander angeordnet sind und jeweils eine Mehrzahl von Leuchtmitteln aufweisen. Außerdem weist die Anzeigevorrichtung zwei Halteelemente, zwischen denen die einzelnen Trägerelemente gespannt sind, und eine Steuerung zur Ansteuerung der einzelnen Leuchtmittel auf.This object is achieved by a display device having the features of
Bei der erfindungsgemäßen Anzeigevorrichtung sind die Leuchtmittel der einzelnen Trägerelemente in mindestens zwei Spalten nebeneinander und in mehreren Reihen untereinander angeordnet, wobei der vertikale Abstand a zweier benachbarter Leuchtmittel einer Spalte dem horizontalen Abstand b zweier benachbarter Leuchtmittel einer Reihe entspricht. Außerdem ist der Abstand c zwischen benachbarten Trägerelementen so gewählt, dass der horizontale Abstand zweier benachbarter Leuchtmittel zweier benachbarter Trägerelemente dem horizontalen Abstand b zweier benachbarter Leuchtmittel eines Trägerelements entspricht. Bei einer fertig montierten Anzeigevorrichtung mit einer Mehrzahl von nebeneinander angeordneten flexiblen Trägerelementen ist dadurch sowohl der vertikale Abstand a als auch der horizontale Abstand b benachbarter Leuchtmittel gleich groß, sodass von der Anzeigevorrichtung ein gleichmäßiges, homogenes und streifenfreies Bild erzeugt werden kann.In the display device according to the invention, the lamps of the individual carrier elements are arranged in at least two columns next to one another and in several rows one below the other, the vertical distance a between two adjacent lamps in a column corresponding to the horizontal distance b between two adjacent lamps in a row. In addition, the distance c between adjacent support elements is chosen such that the horizontal distance between two adjacent light sources of two adjacent support elements corresponds to the horizontal distance b between two adjacent light sources of one support element. In the case of a fully assembled display device with a plurality of flexible support elements arranged next to one another, both the vertical distance a and the horizontal distance b between adjacent lamps are the same, so that the display device can generate a uniform, homogeneous and stripe-free image.
Die Anzahl der Leuchtmittel in einer Spalte ist dabei in der Regel wesentlich größer als die Anzahl der Leuchtmittel in einer Reihe. Bei einem ca. 1 m langem Trägerelement können beispielsweise ca. 20 bis 65 Leuchtmittel in einer Spalte untereinander angeordnet sein, abhängig vom Abstand der Leuchtmittel zueinander und dem Durchmesser der einzelnen Leuchtmittel.The number of lamps in a column is usually much larger than the number of lamps in a row. In the case of an approximately 1 m long carrier element, for example, approximately 20 to 65 lamps can be arranged one below the other in a column, depending on the distance between the lamps and the diameter of the individual lamps.
Im Unterschied zu den im Markt bekannten Anzeigevorrichtungen besteht die erfindungsgemäße Anzeigevorrichtung weder aus mehreren rechteckigen, starren Modulen, noch weist sie einen starren, geschlossenen Halterahmen auf. Auch die einzelnen Leuchtmittel, bei denen es sich insbesondere um LEDs handelt, sind nicht auf einem starren Trägerelement angeordnet oder von einer starren Röhre umgeben. Die erfindungsgemäße Anzeigevorrichtung ist vielmehr aus mehreren flexiblen, streifenförmigen Trägerelementen aufgebaut, die jeweils mit einem vorgegebenen Abstand nebeneinander angeordnet sind, wobei die einzelnen Trägerelemente mit ihren beiden Enden in den beiden Halteelementen befestigt sind. Die Anzeigevorrichtung kann dabei mit ihrem ersten, oberen Halteelement beispielsweise an einem Gerüst, einer Wand oder einem Kran befestigt sein.In contrast to the display devices known on the market, the display device according to the invention consists neither of several rectangular, rigid modules, nor does it have a rigid, closed holding frame. The individual light sources, which are in particular LEDs, are also not arranged on a rigid carrier element or surrounded by a rigid tube. Rather, the display device according to the invention is constructed from a plurality of flexible, strip-shaped carrier elements which are each arranged next to one another at a predetermined distance, the individual carrier elements being fastened with their two ends in the two holding elements. The display device can be attached with its first, upper holding element, for example, to a scaffolding, a wall or a crane.
Dadurch, dass die erfindungsgemäße Anzeigevorrichtung keine starren Module, sondern mehrere flexible Trägerelemente aufweist, weist die Anzeigevorrichtung im Vergleich zu bekannten, aus einzelnen Modulen aufgebauten Anzeigevorrichtungen ein deutlich geringeres Gewicht auf. Die Gewichtsersparnis gegenüber herkömmlichen Modulen bzw. Paneelen kann dabei mehr als 50 % betragen. Durch die Verwendung von flexiblen Trägerelementen, die vor dem Aufbau zusammengelegt oder zusammengerollt sein können, ergibt sich auch eine erhebliche Platzeinsparung beim Transport. Schließlich ergibt sich bei der erfindungsgemäßen Anzeigevorrichtung auch eine erhebliche Zeitersparnis beim Aufbau, da die einzelnen flexiblen Trägerelemente auf dem Boden liegend mit den beiden Halteelementen verbunden werden können und anschließend die Anzeigevorrichtung an dem ersten, oberen Halteelement, ähnlich wie eine Leinwand oder ein Vorhang, hochgezogen werden kann, beispielsweise mithilfe eines Krans oder montiert an einer Traverse mittels eines Traversenlift.Due to the fact that the display device according to the invention does not have any rigid modules, but several flexible carrier elements, the display device has a significantly lower weight in comparison to known display devices made up of individual modules. The weight saving compared to conventional modules or panels can be more than 50%. The use of flexible support elements, which can be folded or rolled up before assembly, also results in a considerable saving of space during transport. Finally, the display device according to the invention also saves a considerable amount of time during assembly, since the individual flexible support elements lying on the floor can be connected to the two holding elements and then the display device can be pulled up on the first, upper holding element, similar to a screen or a curtain can be, for example, using a crane or mounted on a traverse using a traverse lift.
Ein weiterer Vorteil der erfindungsgemäßen Anzeigevorrichtung besteht darin, dass dadurch, dass die einzelnen Trägerelemente mit Abstand zueinander angeordnet sind, zwischen den einzelnen Trägerelementen schlitzförmige Freiräume bestehen, sodass die montierte Anzeigevorrichtung im Vergleich zu herkömmlichen, starren Anzeigevorrichtungen wesentlich weniger windanfällig ist, da der Wind durch die Freiräume durchtreten kann. Durch das deutlich reduzierte Gewicht der Anzeigevorrichtung verringert sich außerdem die Verletzungsgefahr, sollte eine Anzeigevorrichtung gleichwohl einmal umstürzen.A further advantage of the display device according to the invention is that because the individual support elements are arranged at a distance from one another, there are slot-shaped free spaces between the individual support elements, so that the mounted display device is significantly less susceptible to wind than conventional, rigid display devices, since the wind blows through can pass through the spaces. The significantly reduced weight of the display device also reduces the risk of injury should a display device nevertheless fall over.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung bestehen die einzelnen flexiblen Trägerelemente zumindest teilweise aus einem Kunststoffmaterial, insbesondere aus einem thermoplastischen Kunststoffmaterial, beispielsweise aus Polyethylen, Polycarbonat oder Polyamid. Alternativ kann für das Material der Trägerelemente auch ganz oder teilweise ein Gummi oder ein Silikon verwendet werden. Die Wahl von Kunststoff, Gummi oder Silikon für das Material der Trägerelemente hat dabei den Vorteil, dass die Trägerelemente mit dem darin angeordneten Leuchtmitteln einfach hergestellt werden können, wobei die Flexibilität der Trägerelemente in Abhängigkeit von der Länge und der Breite der Trägerelemente angepasst werden kann. Damit die Trägerelemente beim Transport platzsparend verstaut werden können, ist eine möglichst hohe Flexibilität vorteilhaft. Andererseits dürfen die Trägerelemente jedoch nicht so flexibel bzw. elastisch sein, dass sich die einzelnen Trägerelemente im montierten Zustand bei Wind zu stark bewegen, da dies die Bildqualität der Anzeigevorrichtung negativ beeinflussen würde.According to an advantageous embodiment of the invention, the individual flexible carrier elements consist at least partially of a plastic material, in particular of a thermoplastic plastic material, for example of polyethylene, polycarbonate or polyamide. Alternatively, a rubber or a silicone can also be used in whole or in part for the material of the carrier elements. The choice of plastic, rubber or silicone for the material of the support elements has the advantage that the support elements with the lamps arranged therein can be easily produced, the flexibility of the support elements being able to be adjusted depending on the length and the width of the support elements. The greatest possible flexibility is advantageous so that the carrier elements can be stowed away in a space-saving manner during transport. On the other hand, however, the support elements must not be so flexible or elastic that the individual support elements move too much in the installed state in the wind, since this would adversely affect the image quality of the display device.
Um die Stabilität und insbesondere die Verwindungssteifigkeit der einzelnen Trägerelemente im montierten Zustand zu erhöhen, sind in den einzelnen flexiblen Trägerelementen jeweils mindestens ein, vorzugsweise zwei metallische Seile, insbesondere ein oder zwei Stahlseile integriert. Das mindestens eine Seil erstreckt sich dabei im Wesentlichen über die gesamte Länge der flexiblen Trägerelemente, sodass die beiden Enden der einzelnen Seile jeweils im Bereich der beiden Enden der einzelnen flexiblen Trägerelemente angeordnet sind. Die Enden der Seile weisen dabei vorzugsweise ein Fixierungselement, beispielsweise eine Öse oder eine Schlaufe auf, sodass die Seile auch zum Verspannen der Trägerelemente genutzt werden können. Hierzu sind in den Enden der flexiblen Trägerelemente korrespondierend zu den Fixerelementen an den Seilen Ausnehmungen ausgebildet, sodass die Seile und damit auch die Trägerelemente mithilfe von korrespondierenden Befestigungselementen, beispielsweise Schrauben oder Befestigungsstiften, in den beiden Halteelementen befestigt werden können.In order to increase the stability and in particular the torsional rigidity of the individual support elements in the assembled state, at least one, preferably two, metal cables, in particular one or two steel cables, are integrated in each of the individual flexible support elements. The at least one cable extends essentially over the entire length of the flexible support elements, so that the two ends of the individual cables are each arranged in the region of the two ends of the individual flexible support elements. The ends of the ropes preferably have a fixing element, for example an eyelet or a loop, so that the ropes can also be used to brace the support elements. For this purpose, recesses are formed in the ends of the flexible support elements corresponding to the fixation elements on the ropes, so that the ropes and thus also the support elements can be fastened in the two holding elements using corresponding fastening elements, for example screws or fastening pins.
Um die Montage der Anzeigevorrichtung weiter zu erleichtern, sind die einzelnen flexiblen Trägerelemente mit ihrem ersten Ende vorzugsweise an dem ersten Halteelement eingehängt und mit ihrem zweiten Ende jeweils derart in dem zweiten Halteelement aufgenommen, dass die flexiblen Trägerelemente zwischen dem ersten Halteelement und dem zweiten Halteelement verspannt werden können. Dazu sind am zweiten Halteelement entsprechende Spannelemente zum Spannen der flexiblen Trägerelemente vorgesehen. Eine lösbare Befestigung der einzelnen Trägerelemente an den beiden Halteelementen ermöglicht es außerdem, defekte Trägerelemente einzelne, einfach und schnell auszutauschen.In order to further facilitate the assembly of the display device, the individual flexible support elements are preferably suspended with their first end on the first holding element and are each received with their second end in the second holding element in such a way that the flexible support elements are clamped between the first holding element and the second holding element can become. Corresponding clamping elements are provided for this purpose on the second holding element intended for tensioning the flexible support elements. A detachable attachment of the individual carrier elements to the two holding elements also makes it possible to exchange defective carrier elements individually, simply and quickly.
Zur einfachen Montage der Anzeigevorrichtung sind darüber hinaus vorzugsweise am ersten Ende oder am zweiten Ende der einzelnen flexiblen Trägerelemente jeweils Anschlusselemente zur elektrischen Verbindung der einzelnen Leuchtmittel eines Trägerelements mit der Steuerung vorgesehen. Als Anschlusselemente können beispielsweise Steckkontakte vorgesehen sein, zu denen dann die Steuerung korrespondierende Gegensteckkontakte aufweist. Alternativ dazu kann die elektrische Verbindung zwischen den einzelnen flexiblen Trägerelementen bzw. den darin angeordneten und über Leitungen verbundenen Leuchtmitteln und der Steuerung auch über Schleifkontakte oder Federkontakte erfolgen. Die Schleifkontakte oder Federkontakte sind dabei vorzugsweise an der Steuerung vorgesehen und kontaktieren entsprechende Kontaktflächen an den Enden der Trägerelemente, wenn die Trägerelemente mit den Halteelementen verbunden sind.For easy assembly of the display device, connection elements for the electrical connection of the individual illuminants of a carrier element to the controller are preferably provided at the first end or at the second end of the individual flexible carrier elements. For example, plug-in contacts can be provided as connection elements, for which the controller then has corresponding mating plug-in contacts. As an alternative to this, the electrical connection between the individual flexible carrier elements or the lighting means arranged therein and connected via lines and the controller can also be made via sliding contacts or spring contacts. The sliding contacts or spring contacts are preferably provided on the controller and make contact with corresponding contact surfaces on the ends of the carrier elements when the carrier elements are connected to the holding elements.

Die einzelnen Trägerelemente 2 weisen jeweils eine Mehrzahl von Leuchtmitteln 3 auf, die in mindestens zwei Spalten nebeneinander und in mehreren Reihen untereinander angeordnet sind. Neben den bei den Ausführungsbeispielen vorgesehenen zwei Spalten können insbesondere auch drei Spalten oder vier Spalten von Leuchtmitteln 3 nebeneinander an einem Trägerelement 2 angeordnet sein. Die Anzahl der in einer Spalte untereinander angeordneten Leuchtmittel, d. h. die Anzahl der Reihen von nebeneinander angeordneten Leuchtmitteln 3 ist dabei wesentlich größer als die Anzahl der Spalten. Vorliegend weist jedes Trägerelement 74 Leuchtmittel 3 auf, die in zwei Spalten nebeneinander und in insgesamt 38 Reihen untereinander angeordnet sind. Die Anzahl der Leuchtmittel 3 bzw. die Anzahl der untereinander angeordneten Reihen hängt dabei insbesondere von der Länge der flexiblen Trägerelemente 2 ab.The
Wie insbesondere aus den vergrößerten Darstellungen gemäß den
Bei beiden Ausführungsbeispielen weisen die einzelnen flexiblen Trägerelemente 2 weisen jeweils eine Breite B von 35 mm und die einzelnen Leuchtmittel 3 jeweils einen Durchmesser von 10 mm auf. Der vertikale Abstand a und der horizontale Abstand b benachbarte Leuchtmittel 3 beträgt 25 mm, jeweils bezogen auf den Mittelpunkt der einzelnen Leuchtmittel 3. Daraus ergibt sich, dass der Abstand c zwischen zwei benachbarten Trägerelementen 2 jeweils 15 mm beträgt, sodass auch der horizontale Abstand zweier benachbarter Leuchtmittel 3 zweier benachbarter Trägerelemente 25 mm beträgt, also dem horizontalen Abstand b zweier benachbarter Leuchtmittel 3 einer Reihe eines Trägerelements 2 entspricht.In both exemplary embodiments, the individual
Weisen die verwendeten flexiblen Trägerelemente 2 eine andere Breite auf, so können sich entsprechend auch der vertikale Abstand a und der horizontale Abstand b benachbarter Leuchtmittel 3 sowie der Abstand c zwischen zwei benachbarten Trägerelementen 2 ändern. Bei Trägerelementen 2, die beispielsweise eine Breite B von 25 mm aufweisen, kann der vertikale Abstand a und der horizontale Abstand b benachbarte Leuchtmittel 3 jeweils 15 mm betragen, sodass der Abstand c zwischen zwei benachbarten Trägerelementen 2 jeweils 5 mm beträgt, vorausgesetzt, dass die Leuchtmittel 3 jeweils einen Durchmesser von 10 mm aufweisen.If the
Die erfindungsgemäße Anzeigevorrichtung 1 weist neben den flexiblen Trägerelementen 2 und den Halteelementen 4a, 4b noch eine Steuerung 5 zur Ansteuerung der einzelnen Leuchtmittel 3 auf, die auf der Rückseite der Anzeigevorrichtung 1 montiert ist. Bei dem Ausführungsbeispiel der Anzeigevorrichtung 1 gemäß
Beim Befestigen der einzelnen Trägerelemente 2 in den Halteelementen 4a, 4b können dann entsprechende Befestigungselemente, beispielsweise Schrauben oder Befestigungsstifte, durch die Ausnehmungen 9 im Trägerelement 2 in die Ösen 8 in den Stahlseilen 7 eingebracht werden, so dass die flexiblen Trägerelemente 2 eine hohe Verwindungssteifigkeit aufweisen, auch wenn die Trägerelemente 2 aus einem Kunststoffmaterial, einem Gummi oder einem Silikon bestehen. Durch die Anordnung der Stahlseile 7 in den Trägerelementen 2 verbessert sich darüber hinaus die Möglichkeit, die einzelnen Trägerelemente 2 zwischen den beiden Halteelementen 4a und 4b zu verspannen, so dass die Trägerelemente 2 im fertig montierten Zustand der Anzeigevorrichtung 1 ausreichend straff gespannt sind und somit nicht durchhängen können. Auch hierdurch wird die Qualität der auf der Anzeigevorrichtung 1 dargestellten Bilder verbessert.When fastening the
Zum Anbringen der Anzeigevorrichtung 1 beispielsweise an einem Gerüst oder einem Kran ist am ersten Halteelement 4a eine Aufhängung 10 angebracht, die der Befestigung der Anzeigevorrichtung 1 dient. Die Aufhängung 10 kann außerdem zum Hochziehen der, zuvor bei der Montage auf dem Boden liegenden, Anzeigevorrichtung 1 genutzt werden kann. Zum Verspannen der Anzeigevorrichtung 1 kann auch die zweite Haltevorrichtung 4b eine entsprechende Aufhängung aufweisen, die beispielsweise in ein Gegenlager am Boden eingehängt werden kann. Wie aus
