Wie in Fig. 1 stark vereinfacht dargestellt, eignet sich die Anzeigevorrichtung 14 der vorliegenden Erfindung insbesondere als so genanntes Fassadendisplay, das an einer Fassade 10 eines Bauwerks, insbesondere eines Gebäudes zum Beispiel vor einer großflächigen Fensterfront 10 zur Anzeige von Informationen angebracht werden kann. Dabei können grundsätzlich beliebige Informationen auf dem Fassadendisplay dargestellt werden, insbesondere sowohl alphanumerische als auch Bildzeichen, sowohl Standbilder, Laufschriften als auch Echtzeit-Videos und dergleichen. Die Anzeigevorrichtung 14 der Erfindung ist selbstverständlich nicht auf bestimmte Bauwerksarten oder -größen oder auf das Vorhandensein von großflächigen Fensterfronten 12 beschränkt, auch wenn die Erfindung nachfolgend am Beispiel einer Gebäudefassade mit großflächiger Fensterfront näher erläutert wird.As shown greatly simplified in Fig. 1, the
Die erfindungsgemäße Anzeigevorrichtung 14 weist mehrere Träger 16 auf, die in der Darstellung von Fig. 1 in horizontaler Ausrichtung an der Gebäudefassade 10 vorgesehen sind. Wahlweise ist es auch denkbar, diese Träger 16 in vertikaler Ausrichtung an der Fassade 16 anzubringen. Grundsätzlich ist es aber möglich, die Träger unter einem beliebigen Winkel und sogar in zueinander unterschiedlicher Ausrichtung an der Fassade 16 zu montieren.The
Die einzelnen Träger 16 sind als lang gestreckte Profilkörper 18 zum Beispiel in der Form von Lamellen in der Art etwa eines Sonnenschutzrollos ausgebildet. Diese an der Außenseite oder Innenseite der Gebäudefassade 10 anzubringenden Profilkörper 18 bestehen zum Beispiel aus einem Metall, wie beispielsweise Aluminium, bzw. dessen Legierung oder einem wetterfesten Kunststoff.The
Wie schematisch in Fig. 2 dargestellt, weist der lang gestreckte Profilkörper 18 an einer schmalen Längsseite eine erste Ausnehmung 20 auf, die sich in der Längsrichtung des Profilkörpers 18 im Wesentlichen über dessen gesamte Länge erstreckt. Die erste Ausnehmung 20 ist dabei an der Längsseite des Profilkörpers 18 vorgesehen, welche in der Betriebsstellung der Anzeigevorrichtung 14 der Gebäudefassade 10 abgewandt ist, sodass die Öffnung der ersten Ausnehmung 20 von der Fassade 10 weg gerichtet ist. Diese erste Ausnehmung 20 dient der Aufnahme einer Platine 24 mit mehreren Leuchtdioden 26 und Elektronikkomponenten 28, welche anhand der Fig. 3 und 4 unten näher erläutert werden. Wie bereits in Fig. 2 zu erkennen, ist die Platine 24 in eine Schutzmasse 30 eingebracht bzw. integriert, wobei die Leuchtdioden 26 wenigstens teilweise aus der ersten Ausnehmung 20 des Profilkörpers 18 heraus ragen oder zumindest der Außenseite des Profilkörpers 18 zugewandt sein sollten. Die in der Schutzmasse 30 integrierte Platine 24 mit den Leuchtdioden 26 ist fest (z.B. mittels Presspassung, Verklebung, Verrastung, Integration oder dergleichen) in die erste Ausnehmung 20 eingesetzt bzw. eingeschoben. Die Schutzmasse besteht zum Beispiel aus einem elektrisch isolierenden, gegen Umwelteinflüsse beständigen Material.As shown schematically in FIG. 2, the
Auf der der ersten Ausnehmung 20 abgewandten, d.h. der in der Betriebsstellung der Anzeigevorrichtung 14 der Gebäudefassade 10 zugewandten schmalen Längsseite weist der Profilkörper 18 zum Beispiel eine zweite Ausnehmung 22 auf. Mittels dieser zweiten Ausnehmung 22 kann der Träger 16 an einem Trägergestell (nicht dargestellt) zum Beispiel mittels Klemmung, Schraubung oder Presspassung befestigt werden, wobei das Trägergestell seinerseits an der Gebäudefassade 10 angebracht ist. Als Befestigungsvorrichtung kann der Träger anstatt oder zusätzlich zu der zweiten Ausnehmung 22 auch andere Elemente aufweisen, mittels derer er an dem Trägergestell mittels Klemmung, Presspassung, Verschraubung, Verklebung, Verschweißung oder dergleichen montiert werden kann. Die Stelle der Befestigungsvorrichtung 22 ist außerdem nicht auf die Längsseite des Profilkörpers 18 beschränkt und muss sich auch nicht über die gesamte Länge des Profilkörpers erstrecken. In einer besonders vorteilhaften Ausgestaltung können die Träger 16 so an dem Trägergestell (nicht dargestellt) montiert und/oder das Trägergestell so ausgebildet und/oder angeordnet sein, dass die Träger 16 um ihre Längsachsen zwischen einer Betriebsstellung und einer Nicht-Betriebsstellung der Anzeigevorrichtung 14 bzw. der Sonnenschutzvorrichtung schwenkbar sind.On the
Auf einer Platine 24 sind neben den für die Ansteuerung der Leuchtdioden 26 benötigten Elektronikkomponenten 28 mehrere Leuchtdiodengruppen 27 vorgesehen, wie in der Darstellung von Fig. 3 veranschaulicht. Jede Leuchtdiodengruppe 27 besteht aus mehreren, vorzugsweise verschiedenfarbigen Leuchtdioden 26, um beliebig farbige Bildpunkte bilden zu können. Hierbei ist die vorliegende Erfindung aber nicht nur auf solche Leuchtdiodengruppen 27 beschränkt, sondern die Leuchtdiodengruppen 27 können auch nur eine bis drei Leuchtdioden 26 oder mehr als vier Leuchtdioden 26 aufweisen, sie können zueinander unterschiedliche Anzahlen von Leuchtdioden 26 aufweisen, und sie müssen keine verschieden farbigen Leuchtdioden 26 enthalten.On a
Der Abstand zwischen den einzelnen Leuchtdiodengruppen 27 auf einer Platine 24 kann entweder gleich oder verschieden zu dem Abstand der Träger 16 zueinander gewählt sein. Mit anderen Worten kann der Bildpunktabstand in horizontaler und vertikaler Richtung wahlweise symmetrisch oder asymmetrisch gewählt sein, was bei einer Ansteuerung der Leuchtdiodengruppen 27 durch eine Steuereinheit (nicht dargestellt) natürlich entsprechend berücksichtigt werden muss. Die Variabilität der erfindungsgemäßen Anzeigevorrichtung 14 ist durch die grundsätzliche beliebig winklige und sogar zueinander unterschiedliche Ausrichtung der einzelnen Träger noch verstärkt.The distance between the individual light-emitting
Wie in dem vergrößerten Ausschnitt X in Fig. 4 dargestellt, weist jede Platine 24 im Bereich ihrer einen Stirnseite (vorzugsweise an beiden Stirnseiten) mehrere erste Anschlüsse 32 auf. Diese ersten Anschlüsse 32 dienen der Kopplung der Platinen 24 der Träger 16 mit der Steuereinheit (nicht dargestellt) zur elektrischen Verbindung sowie der Datenübertragung.As shown in the enlarged section X in Fig. 4, each
Die Platine weist außerdem im Bereich ihrer Stirnseite (vorzugsweise an beiden Stirnseiten) weitere Anschlüsse 34 auf. Diese weiteren Anschlüsse 34 dienen der Kopplung mehrerer Platinen 24, die in Reihe hintereinander in einem Träger 16 angeordnet sind, zur elektrischen Verbindung und Datenübertragung. Die Kopplung erfolgt über ein geeignetes Verbindungselement 36 wie zum Beispiel einen Steckverbinder. Wie in Fig. 3 angedeutet, können so mehrere Platinen 24 in Längsrichtung miteinander verbunden und in einen Träger 16 eingebaut werden. Dies ist von Vorteil, da die Längen der Platinen 24 aus fertigungstechnischen und Handhabungsgründen im Allgemeinen begrenzt sind. Im Rahmen der Erfindung ist aber ebenso möglich, die ersten Anschlüsse 32 und die weiteren Anschlüsse 34 als gemeinsame Anschlüsse 32, 34 vorzusehen.The board also has in the region of its end face (preferably on both end faces)
