Abstract
Description
Die Erfindung betrifft eine Leuchtreklame, insbesondere eine Konturbeleuchtung, mit einer Mehrzahl von Leuchtdioden, die auf eine Mehrzahl von Arrays aufgeteilt sind und von einer Mehrzahl von Stromquellen gespeist sind.The invention relates to a neon sign, in particular contour lighting with a plurality of light-emitting diodes, which are divided into a plurality of arrays and by a plurality of power sources are fed.
Konturbeleuchtungen sind eine spezielle Art von Leuchtreklamen, mit denen an Gebäuden bestimmte Konturen nachgezogen werden. Sie sind häufig in speziellen Farben gehalten, die den Firmenfarben des jeweiligen Unternehmens entsprechen. Während in der Vergangenheit für derartige Konturbeleuchtungen vornehmlich Leuchtstoffröhren eingesetzt wurden, finden in jüngster Zeit zunehmend auch Leuchtdioden als Lichtquellen Verwendung. Zur leichteren Montierbarkeit sind diese Leuchtdioden jeweils in Gruppen zu Einheiten zusammengefaßt, die "Arrays" genannt werden. Eine Mehrzahl derartiger Arrays, die hinter- und ggf. nebeneinander gelegt sind, zeichnen so in gewünschter Weise die Kontur nach.Contour lighting is a special type of neon sign, with which certain contours are drawn on buildings become. They are often in special colors kept that the company colors of each company correspond. While in the past for such Contour lighting mainly uses fluorescent tubes have been finding more and more recently Light emitting diodes used as light sources. For easier These LEDs can be assembled in groups combined into units called "arrays". A plurality of such arrays, the back and possibly are placed side by side, so draw in the desired Show the contour.
Bei den bekannten Konturbeleuchtungen dieser Art waren bisher alle Leuchtdioden innerhalb eines Arrays in Serie geschaltet und wurden von ein und derselben Stromquelle gespeist. Fiel eine dieser Stromquellen im Laufe der Zeit aus, so bedeutete dies, daß das gesamte Array dunkel wurde und eine deutlich erkennbare Lücke innerhalb der Konturbeleuchtung hinterließ. Reparaturmaßnahmen waren die unausweichliche Folge.In the known contour lighting of this type So far, all LEDs within an array in series switched and were from the same power source fed. One of these power sources fell over the course of the Time out, this meant that the entire array was dark was and a clearly recognizable gap within the Contour lighting left. Repair measures were the inevitable consequence.
Aufgabe der vorliegenden Erfindung ist es, eine Leuchtreklame der eingangs genannten Art so auszugestalten, daß beim Ausfall einer Stromquelle das optische Erscheinungsbild nicht nennenswert beeinträchtigt wird.The object of the present invention is to provide a neon sign of the type mentioned at the beginning, that if a power source fails, the visual appearance is not significantly affected.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Leuchtdioden auf einem Array aus unterschiedlichen Stromquelle gespeist sind. Fällt daher eine dieser Stromquellen aus, so strahlen die weiteren Leuchtdioden im selben Array weiterhin Licht aus; der Ausfall einer einzigen oder nur weniger Leuchtdioden im Array wird insbesondere in der Entfernung optisch kaum wahrgenommen. Die Leuchtreklame kann daher zunächst ohne Reparatur weiterbetrieben werden.This object is achieved in that the LEDs on an array of different Are powered. Therefore one of these power sources falls the other LEDs in the same array continues to light out; the failure of one single or only a few LEDs in the array hardly perceptible, especially in the distance. The neon sign can therefore initially be repaired continue to be operated.
Von besonderem Vorteil ist, wenn die Zahl von Leuchtdioden innerhalb eines Arrays mit der Zahl der Stromquellen übereinstimmt, derart, daß jede Leuchtdiode innerhalb eines Arrays von einer anderen Stromquelle gespeist ist. Der Ausfall einer Stromquelle hat also in dem Array nur den Ausfall einer einzigen Leuchtdiode zur Folge.It is particularly advantageous if the number of light emitting diodes within an array with the number of power sources coincides, such that each light emitting diode within of an array is powered by another power source. The failure of a power source is therefore in the array only the failure of a single LED results.
Zweckmäßigerweise sind Leuchtdioden unterschiedlicher Arrays in Serie geschaltet. Hierdurch läßt sich die Anzahl der Stromquellen reduzieren, ohne daß der gewünschte Effekt nennenswert beeinträchtigt wird: Fällt eine der Stromquellen aus, bedeutet dies, daß in den Arrays, die in Serie geschaltete Leuchtdioden enthalten, jeweils die von der defekten Stromquelle gespeisten Leuchtdioden ausfallen. Da diese aber einen verhältnismäßig großen Abstand voneinander aufweisen, bleibt die hiermit verbundene Dunkelstelle in der Konturbeleuchtung klein und wird auf die Entfernung praktisch nicht wahrgenommen.Light-emitting diodes are expediently different Arrays connected in series. This allows the Reduce the number of power sources without the desired one Effect is significantly impaired: falls one of the power sources, it means that in the Arrays that contain light-emitting diodes connected in series, each powered by the defective power source LEDs fail. But since this is relative have a large distance from each other, the associated dark spot in the contour lighting small and is practically invisible from a distance.
Dabei wird wiederum diejenige Ausgestaltung bevorzugt, bei der alle Leuchtdioden, die innerhalb der verschiedenen Arrays in derselben geometrischen Position angeordnet sind, in Serie geschaltet sind. In diesem Falle haben die in Serie gelegten Leuchtdioden, die bei Ausfall einer Stromquelle gemeinsam erlöschen, den größtmöglichen Abstand voneinander.Again, the preferred embodiment is where all the light emitting diodes within the different Arrays arranged in the same geometric position are connected in series. In this case have the light-emitting diodes in series, in the event of failure power source go out together, the greatest possible Distance from each other.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert; die einzige Figur zeigt schematisch ein Blockschaltbild für einen Ausschnitt einer Konturbeleuchtung.An embodiment of the invention is as follows explained in more detail with reference to the drawing; the only figure shows schematically a block diagram for a section contour lighting.
Die Konturbeleuchtung ist in der Zeichnung insgesamt mit dem Bezugszeichen 1 gekennzeichnet. Sie setzt sich segmentartig aus einer Vielzahl von Leuchtdiodenarrays A zusammen, von denen in der Zeichnung zwei, A1 und A2 dargestellt sind und die, aneinander gereiht, an einem Gebäude eine zu beleuchtende Kontur nachzeichnen. Jedes Leuchtdiodenarray A1, A2 enthält eine Mehrzahl von Leuchtdioden D, im dargestellten Ausführungsbeispiel jeweils sechs Leuchtdioden D1 bis D6. Die Leuchtdioden D jedes Arrays A sitzen auf einer gemeinsamen Platine und sind auf diese Weise zu einer körperlichen Einheit zusammengefaßt.The contour lighting is overall in the drawing marked with the reference number 1. she takes a seat segment-like from a multitude of light-emitting diode arrays A together, two of which in the drawing, A1 and A2 are shown and which, strung together, on one Draw a contour of the building to be illuminated. Each Light-emitting diode array A1, A2 contains a plurality of light-emitting diodes D, each in the illustrated embodiment six LEDs D1 to D6. The light emitting diodes D each Arrays A sit on a common board and are open thus combined into one physical unit.
Die Leuchtdioden D der verschiedenen Arrays A innerhalb der Konturbeleuchtung 1 werden von mehreren Stromverquellen N gespeist. Im dargestellten Ausführungsbeispiel entspricht die Zahl der Stromquellen N1 bis N6 der Zahl der Leuchtdioden D1 bis D6 im Array. Jeweils die ersten Leuchtdioden D1 in den verschiedenen Arrays A sind in Serie geschaltet und werden von der ersten Stromquelle N1 versorgt. Entsprechend sind die n-ten Dioden Dn in den verschiedenen Arrays A in Serie geschaltet und werden aus der n-ten Stromquelle Nn gespeist.The light emitting diodes D of the various arrays A within the contour lighting 1 are from several power sources N fed. In the illustrated embodiment corresponds to the number of current sources N1 to N6 Number of LEDs D1 to D6 in the array. Each the first LEDs D1 in the various arrays A are connected in series and are from the first Power source N1 supplied. The nth are corresponding Diodes Dn in the various arrays A connected in series and are fed from the nth current source Nn.
Der Sinn der geschilderten Schaltung ist folgender:
Funktionieren alle Stromquellen Nn ordnungsgemäß, so
werden alle Leuchtdioden D innerhalb aller Arrays A
ordnungsgemäß bestromt und strahlen entsprechend Licht
aus. Fällt dagegen eine Stromquelle, z.B. N1, aus, so
bleibt die Stromversorgung der zugeordneten Leuchtdioden
D, im Beispiel diejenige der Leuchtdioden D1, aus; die
entsprechenden Leuchtdioden D bleiben daher dunkel. Da
jedoch die anderen Leuchtdioden D weiterhin von den entsprechenden
Stromquellen N bestromt werden, senden diese
weiterhin Licht aus. Es entsteht auf diese Weise nur eine
punktuelle Dunkelstelle, die auf die Entfernung kaum
erkennbar ist. Das Erscheinungsbild der Konturbeleuchtung
1 bleibt somit beim Ausfall einer einzigen Stromquelle N
im wesentlichen unverändert.The purpose of the circuit described is as follows:
If all current sources Nn function properly, all light-emitting diodes D within all arrays A are properly energized and emit light accordingly. If, on the other hand, a current source, for example N1, fails, the power supply to the associated light-emitting diodes D, that of the light-emitting diodes D1 in the example, remains off; the corresponding light-emitting diodes D therefore remain dark. However, since the other light-emitting diodes D continue to be supplied with current by the corresponding current sources N, they continue to emit light. In this way, only a specific dark spot is created, which is hardly recognizable from a distance. The appearance of the contour lighting 1 thus remains essentially unchanged if a single power source N fails.
