Abstract

The object of the invention is to provide luminous elements of the generic type which are distinguished by a lowering of the outlay on production thereof as well as by a low energy consumption and by robustness. According to the invention, each luminous element has one or more light emitting semiconductor diodes (1) and/or fluorescing means. The LEDs used in this solution, which are connected to a voltage source, open up novel possibilities in the field of advertising. Equally, the luminous elements are suitable for decoration and marking. Owing to the robustness and miniaturisation of the elements, it is possible to represent different geometrical figures such as, for example, a straight line, straight lines arranged at an angle, a circle, a curve, letters, logos and three-dimensional bodies. Fig. 1 illustrates luminous elements arranged in the shape of a cross. <IMAGE>

Description

Es sind bereits Leuchtelemente bekannt, die unter Verwerdung von Glühlampen, welche in einer bestimmten Anordnung vorgesehen sind, für Verkehrsleiteinrichtungen Anwendung finden.Durch eine spezielle elektrische Schaltung können diese Leuchtelemente je nach Anwendungszweck auch als Lauflicht ausgestaltet werden.Luminous elements are already known which are used for traffic control devices using incandescent lamps which are provided in a specific arrangement. Depending on the intended use, these luminescent elements can also be designed as running lights by means of a special electrical circuit.

Für Illumnationszwecke ist ferner die Anwendung von kettenförmig aneinandergereihten Sofittenlampen, die in vorzugsweise durchsichtigen schlauchartig ausgebildeten Körpern angeordnet sind, bekannt.For illustrative purposes, the use of chain-like sofa lamps, which are arranged in preferably transparent tubular bodies, is also known.

Der vorliegenden Erfindung liegt das Problem zugrunde, eine Lösung für Leuchtelemente, die in definierter geometrischer Gestalt angeordnet sind, anzubeten, die sich enerseits durch eine Senkung des Aufwandes zur Herstellung dieser Leuchtelemente sowie andererseits durch einen niedrigeren Energieverbrauch auszeichnet.Die Leuchtelemente sollen keiner Einschränkung hinsichtlich der Betriebsart unterliegen, sich ferner durch Robustheit,durch eine geringe Masse und durch ein geringes Gewicht auszeichnen und damit eine weitere Forderung nach neuen Einsatzmöglichkeiten erfüllen.The present invention is based on the problem of worshiping a solution for lighting elements which are arranged in a defined geometric shape, which is characterized on the one hand by a reduction in the effort for the production of these lighting elements and on the other hand by a lower energy consumption Operating mode subject to, are also characterized by robustness, by a low mass and by a low weight and thus meet another demand for new uses.

Dieses Problem wird nach der Erfirdung mit den Maßnahmen des Anspruches 1 dadurch gelöst,daß jedes Leuchtelement ein oder mehrere Licht emittierende Halbleiterdioden und /oder fluoreszierende Mittel aufweist.Diese Licht emittierenden Halbleiterdioden - allgemein unter der Bezeichnung LED bekannt - zeichnen sich neben einem geringen Energieverbrauch auch dadurch aus, daß sie wesentlich kleiner und unempfindlicher als Glühlampen oder Sofittenlampen sind und vor allem darüber hinaus für den Dauerbetrieb geeignet sind.Se unterlegen damit keiner Einschränkung bezüglich der Betriebsart.Ihr geringes Gewicht und der geringe Stromverbrauch sowie die Robustheit ermöglichen ein breites Einsatzspektrum.This problem is solved according to the invention with the measures of claim 1 in that each lighting element has one or more light-emitting semiconductor diodes and / or fluorescent These light-emitting semiconductor diodes - generally known as LED - are characterized by their low energy consumption and the fact that they are much smaller and less sensitive than incandescent or softened lamps and, above all, are suitable for continuous operation No restrictions with regard to the operating mode. Their low weight, low power consumption and robustness enable a wide range of applications.

Vorzugsweise sind die Leuchtelemente zum Dekorieren und / oder zum Markieren engesetzt.The lighting elements are preferably used for decorating and / or for marking.

Beim Einsatz der Leuchtelelmente zum Dekorieren denen diese in der Regel als Werbeträger, bzw. als optischer Blickfang für das zu werbende Objekt.When using the light elements to decorate them, they are usually used as an advertising medium or as an optical eye-catcher for the object to be advertised.

Die, den LED's eigene Miniaturisierung ermöglicht grundsätzlich neue Lösungen zum Dekorieren und zum Markieren.The miniaturization that LED's own enables fundamentally new solutions for decorating and marking.

Eine Ausgestaltung der Leuchtelemente zeichnet sich dadurch aus, daß diese elektrisch miteinander verbunden sind.An embodiment of the lighting elements is characterized in that they are electrically connected to one another.

Vorzugsweise ist die elektrische Verbindung in der Art, daß die Leuchtelemente in Reihe geschaltet sind.Dadurch wird der Leitungsaufwand auf ein Minimum reduziert.The electrical connection is preferably such that the lighting elements are connected in series, as a result of which the wiring effort is reduced to a minimum.

Ein weiteres Merkmal der Leuchtelemente ist auch darin zu sehen, daß jedes Leuchtelement durch mehrere Leuchtdioden gebildet ist.Another feature of the lighting elements can also be seen in the fact that each lighting element is formed by a plurality of light-emitting diodes.

Mit dieser Maßnahme lassen sich besondere Effekte z.B. beim Dekorieren erzielen.Durch Anordnung mehrerer Leuchtdioden zu einem Leuchtelement wird das Augenmerk des Betrachters gezielt auf das zu werbende Objekt gelenkt, welches besonders hervorgehoben werden soll.With this measure, special effects can be achieved, for example when decorating. By arranging several light-emitting diodes to form a lighting element, the viewer's attention is focused specifically on the object to be advertised, which is particularly emphasized shall be.

Eine weitere Ausgestaltung des Leuchtelementes seht vor, daß die Leuchtdioden zu Diodenpärchen geschaltet sind.A further embodiment of the lighting element provides that the light-emitting diodes are connected to form diode pairs.

Für einen klimasicheren Außenbetrieb sind die Kontaktststellen der Leuchtdioden zweckmäßigerweise mit einem bekannten Mittel, z.B. Epoxidharz, vergossen.Werden dagegen die Leuchtelemente in einem Schlauch oder in einer anderen Umhüllung angeordnet, ist ein Vergießen der Kontaktstellen grundsätzlich nicht erforderlich.For a climate-safe outdoor operation, the contact points of the light-emitting diodes are expediently provided with a known means, e.g. Epoxy resin, potted.If the lighting elements are arranged in a hose or in another covering, potting the contact points is generally not necessary.

Durch die Anordnung und Schaltung der Dioden zu Diodenpärchen besteht eine günstige Möglichkeit, bestimmte geometrische Gebilde, wie z.B. ein Kreuz oder einen Stern,rational darzustellen.The arrangement and connection of the diodes to form a pair of diodes offers an inexpensive option for certain geometrical structures, e.g. a cross or a star to represent rationally.

Obwohl der Einsatz rechteckig ausgebildeter Leuchtdioden bevorzugt ist, können durchaus auch andere geometrische Formen der Leuchtdioden eingesetzt werden.Although the use of rectangular light-emitting diodes is preferred, other geometric shapes of the light-emitting diodes can also be used.

Durch die Robustheit und die Miniaturisierung der Elemente ist es ebenfalls in einer weiteren Ausgestaltung möglich, auch andere geometrische Gebilde, wie z.B. eine Gerade, in einem Winkel angeordnete Geraden, einen Kreis bzw. einen Kreisabschnitt, eine kurve, Buchstaben oder Logos darzustellen.Due to the robustness and miniaturization of the elements, it is also possible in a further embodiment to also use other geometrical structures, such as to represent a straight line, straight lines arranged at an angle, a circle or a segment of a circle, a curve, letters or logos.

Gleichfalls ist es möglich auch dreidimensionale Körper, wie z.B. einen Würfel,eine Kugel oder eine Spirale als Leuchtelement nachzubilden.It is also possible to use three-dimensional bodies, e.g. to reproduce a cube, a ball or a spiral as a light element.

Die Erfindung seiht weiterhin vor, daß wenigstens eine Leuchtdiode und / oder ein fluoreszierendes Mittel mit einer Hülle aus transparentem Werkstoff versehen ist.The invention further provides that at least one light-emitting diode and / or a fluorescent agent is provided with a cover made of transparent material.

Es besteht aber auch die Möglichkeit, daß eine transparente Hülle mehreren Leuchtdioden und /oder fluoreszierenden Mitteln zur Fixierung ihrer geometrischen Anordnung zugeordnet ist.But there is also the possibility that a transparent envelope is assigned to several light emitting diodes and / or fluorescent means for fixing their geometric arrangement.

Als transparente Hülle kommen sowohl flexible als auch unflexible Materalen zum Einsatz.Both flexible and inflexible materials are used as the transparent cover.

Neben der Fixierung der Leuchtduden betet die Hülle auch einen Schutz gegen mechanische Beschädigung.In addition to fixing the light fixtures, the cover also protects against mechanical damage.

Entsprechend dem jeweiligen Einsatzzweck ist es in einer weiteren Modifizierung möglich, daß die Leuchtelemente als Dauerlicht, als Blinklicht oder als Lauflicht elektronisch geschaltet sind.Selbstverständlich sind auch Kombinationen der einzelnen Folgen untereinander möglich.Depending on the intended use, in a further modification it is possible for the lighting elements to be electronically switched as permanent light, flashing light or running light. Of course, combinations of the individual sequences are also possible.

Insbesondere beim Impulsbetrieb ist als Vorteil zu verzeichnen, daß dieser keinen negativen Einfluß auf die Lebensdauer der eingesetzten Leuchtdioden hat.In pulse mode in particular, it is an advantage that this has no negative influence on the service life of the light-emitting diodes used.

Als weitere Vorteile gegenüber Glühlampen sind die konstante Helligkeit sowie die geringeren Wärmeverluste zu nennen.The constant brightness and lower heat losses are further advantages compared to incandescent lamps.

Insbesondere beim Einsatz der Leuchtelemente als Dekorations-mittel kann die Attraktivität und der zu erzelende Effekt dadurch erhöht werden, daß die eingesetzten Leuchtelemente unterschiedliche Farben aufweisen.Particularly when using the lighting elements as decoration means, the attractiveness and the effect to be achieved can be increased by the fact that the lighting elements used have different colors.

Durch den Einsatz von Mehrfarbdioden bestehen zusätzliche Möglichkeiten bei der Erzelung optischer Effekte.The use of multicolor diodes offers additional options for the creation of optical effects.

Zweckmäßigerweise sind als Farbkombination die Farben rot, grün, gelb, orange und blau anwendbar.The colors red, green, yellow, orange and blue can expediently be used as the color combination.

Ein neues Einsatzgebiet der Leuchtelemente ist darin zu sehen, daß sie zum Markieren von baulichen Einrichtungen eingesetzt sind.A new area of application for the lighting elements can be seen in that they are used for marking structural facilities.

Zur Erfüllung dieser Forderung sowie zur Erhöhung der Sicherheit allgemein sind speziellen baulichen Anordnungen, wie z.B. Treppen, Geländern, Fluchttüren und dgl. Leuchtelemente zugeordnet.To meet this requirement and to increase safety in general, special structural arrangements, such as Stairs, railings, escape doors and similar lighting elements assigned.

Es liegt ferner auch im Rahmen der Erfindung, diese Leuchtelemente zur Markerung von Fluchtwegen enzusetzen.Damit besteht in Gefahrensituationen für die Betroffenen die Möglichkeit der besseren Orientierung.It is also within the scope of the invention to use these lighting elements to mark escape routes, so that those affected can have better orientation in dangerous situations.

Vorteilhafterweise sind für diese Zwecke von der Stromversorgung unabhängige Leuchtelemente engesetzt.Dabei besteht aber durchaus auch die Möglichkeit sowohl von der Stromversorgung unabhängige als auch an eine Stromversorgung angeschlossene Leuchtelemente sinnvoll zu kombinieren.For this purpose, lighting elements that are independent of the power supply are advantageously used. However, there is also the possibility of meaningfully combining lighting elements that are independent of the power supply and connected to a power supply.

Ein weiteres Merkmal der Leuchtelemente ist auch darin zu sehen, daß die Leuchtdioden kettenförmig angeordnet sind und durch eine gleichartige Reihenschaltung der Leuchtelemente eine vorhandene Gleichspannung abfällt.Another feature of the light-emitting elements can also be seen in the fact that the light-emitting diodes are arranged in a chain and an existing DC voltage drops due to a similar series connection of the light-emitting elements.

Es liegt ebenfalls im Rahmen der Erfindung, daß die Leuchtdioden kettenförmig angeordnet sind und daß durch eine elektrisch gleichartige Reihenschaltung eine vorhandene gleichgerichtete Wechselspannung abfällt.It is also within the scope of the invention that the light-emitting diodes are arranged in a chain and that an existing rectified AC voltage drops through an electrically identical series connection.

Nach einem weiteren Merkmal zeichnen sich die Leuchtelemente auch dadurch aus, daß durch eine elektrische Reihenschaltung von antiparallel geschalteten LED-Pärchen eine vorhandene Wechselspannung abfällt.Vorteilhafterweise ist die vorhandene Wechselspannung gleich der Netzspannung.According to a further feature, the lighting elements are also distinguished by the fact that an existing AC voltage drops due to an electrical series connection of antiparallel-connected LED pairs. Advantageously, the existing AC voltage is equal to the mains voltage.
