Description

Stand der TechnikState of the art

Beleuchtete Informationsträger, Werbetransparente und dekorative Leuchtelemente leiden oft unter dem Mangel, durch die kastenförmige Bauweise nicht oder in nicht ausreichendem Maße dem Umfeld angepaßt zu sein, ja sogar störend zu wirken.Illuminated information carriers, advertising banners and decorative lighting elements often suffer from the fact that their box-shaped design means they are not or not sufficiently adapted to their surroundings, and can even be disruptive.

In anderen Fällen ist der Raumbedarf, die Wärmeentwicklung und/oder das Auswechseln des Leuchtmittels hinderlich und zwingt zu nicht gewollten bautechnischen Kompromissen. - im Falle der Flüssigkristallanzeige fehlt die Nachttauglichkeit.In other cases, the space required, the heat generated and/or the replacement of the light source are a hindrance and force unwanted structural compromises. - in the case of liquid crystal displays, they are not suitable for night use.

Als Beispiel sei das Fluchtschild erwähnt, das z.B. in Theater- oder sonstigen Veranstaltungsräumen den architektonischen Gesamteindruck negativ beeinflußt.One example is the escape sign, which negatively influences the overall architectural impression in theaters or other event spaces.

Um den zwingenden Vorschriften einerseits und dem Umfeld andererseits gerecht zu werden, ist eine Anordnung bekannt (DE 35 42 243 A1), die eine transparente Glasoder Acrylglaspaltte verwendet mit vertieft liegenden Schriften und/oder Symbolen mit besonderer Oberflächenbeschaffenheit. Über eine an der Kante der Platte angebrachte gekapselte Lichtquelle flutet das Licht in die Platte und wird an den Ausnehmungen durch Lichtbrechung sichtbar. - Der Wirkungsgrad hält sich allerdings in Grenzen.In order to meet the mandatory regulations on the one hand and the environment on the other, an arrangement is known (DE 35 42 243 A1) that uses a transparent glass or acrylic glass panel with recessed lettering and/or symbols with a special surface finish. The light floods into the panel via an encapsulated light source attached to the edge of the panel and becomes visible at the recesses through light refraction. - The efficiency is limited, however.

Eine insbesondere der Information dienende Anordnung auf der Basis der Elektrolumineszenz (DE 40 23 693 A1) mit den Vorzügen des sehr flachen Aufbaus, der beliebigen Konturierung der Leuchtflächen und herstelltechnischer Einfachheit kommt dem erfindungsgemäßen Leuchtelement nahe.An arrangement based on electroluminescence (DE 40 23 693 A1) that serves in particular to provide information, with the advantages of a very flat structure, the arbitrary contouring of the luminous surfaces and simplicity in manufacturing, comes close to the luminous element according to the invention.

Als Träger dient bei dieser Erfindung eine herkömmliche Leiterplatte, die entsprechend der gewünschten Kontur geätzt wurde und insoweit die erste Elektrode des einen Kondensator bildenden Leuchtelementes darstellt. Diese Grundplatte wird abgedeckt von einer einseitig transparenten, elektrisch leitenden Folie/Platte, die auf dieser Seite eine Leuchtpigmentschicht trägt. Da die Leiterplatte auf der Rückseite die Steuer- und Treiberbausteine aufzunehmen vermag, ist eine sehr kompakte Bauweise möglich.The carrier used in this invention is a conventional circuit board that has been etched according to the desired contour and thus represents the first electrode of the light element that forms a capacitor. This base plate is covered by a one-sided transparent, electrically conductive film/plate that has a luminous pigment layer on this side. Since the circuit board can accommodate the control and driver components on the back, a very compact design is possible.

-A--A-

Die fehlende Transparenz des Leuchteiementes außerhalb der Leuchtfelder ist ein signifikantes Unterscheidungsmerkmal zu der nachstehend beschriebenen Erfindung. The lack of transparency of the luminous element outside the luminous fields is a significant distinguishing feature from the invention described below.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße Leuchtelement ist extrem flach, kann jede geometrische Form haben und mit einem oder mehreren Leuchtfeldern ausgestattet sein, die nach Bedarf und Ausführung einzeln ansteuerbar sind. Es eignet sich gleichermaßen als Informationsträger wie auch für den Einsatz in der Werbung oder zur Dekoration.The lighting element according to the invention is extremely flat, can have any geometric shape and can be equipped with one or more light fields that can be controlled individually as required and according to the design. It is equally suitable as an information carrier and for use in advertising or for decoration.

Die besondere Bauweise mit zwei transparenten Platten mit jeweils transparenten Elektroden ertaubt außerhalb der Leuchtfelder den freien Durchblick. Dadurch wird das Leuchtelement besonders raumgestalterischen Anforderungen gerecht und kann wirksam die Architektur unterstützen.The special design with two transparent plates, each with transparent electrodes, blocks the view outside the light fields. This means that the light element meets particular interior design requirements and can effectively support the architecture.

Durch die in den Ansprüchen 2 und 3 angeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Anordnung möglich. So kann jede Leuchtfläche für sich angesteuert werden und in Verbindung mit elektronischen Bausteinen z.B. ein Pulsen oder Fliesen des Lichtes dargestellt und so der Aufmerksamkeitsgrad gesteigert werden.The measures set out in claims 2 and 3 allow advantageous further developments and improvements of the arrangement specified in claim 1. Each light surface can be controlled individually and in conjunction with electronic components, for example, a pulsing or tiling of the light can be displayed, thus increasing the level of attention.

Beschreibung der ErfindungDescription of the invention

Ein Ausführungsbeispiel gemäß Anspruch 1 wird anhand nachstehender Figur erläutert: An embodiment according to claim 1 is explained with reference to the following figure:

Das außerhalb der Leuchtfiächen durchsichtige Leuchtelement besteht aus zwei transparenten Platten 1, die jeweils an den sich zugekehrten Seiten 2 eine transparente, elektrisch leitende Beschichtung haben. Die vordere Platte ist mit drei Leuchtfeldern in der Form eines Rahmens 3 und zwei Buchstaben 4 und 5 auf der leitenden Schicht mitThe light element, which is transparent outside the light areas, consists of two transparent plates 1, each of which has a transparent, electrically conductive coating on the facing sides 2. The front plate is provided with three light fields in the form of a frame 3 and two letters 4 and 5 on the conductive layer with

Leuchtpigmenten flächig bedruckt.Printed with luminescent pigments.

Durch innige mechanische Verbindung der Platten wird nach Anlegen einer Wechselspannung über die Einspeisfahnen 6 ein elektrisches Feld aufgebaut, das die Leuchtpigmente der Leuchtfelder 3,4 und 5 zum Leuchten bringt und dennoch freie Durchsicht durch die Platte außerhalb der Leuchtfelder ermöglicht.By applying an alternating voltage via the feed lugs 6, an electric field is created by the intimate mechanical connection of the plates, which causes the luminous pigments of the luminous fields 3, 4 and 5 to glow and yet still allows a clear view through the plate outside the luminous fields.
