Description

Leuchte lamp
Die Erfindung bezieht sich auf eine Leuchte mit einer elektrischen Versorgungseinheit, einem Leuchtenkörper und einer Zuleitung von der Versorgungseinheit zu dem Leuchtenkörper. Aus dem Stand der Technik sind verschiedene Ausführungsformen derartiger Leuchten bekannt. Es weisen dabei die Leuchtenkörper übliche Leuchtmittel wie Leuchtstoffröhren, Halogenleuchten oder dergleichen auf, wobei bei den bekannten Leuchten die an dem Leuchtenkörper anliegende Spannung konstant ist. Derartige Leuchten weisen an sich den Vorteil auf, daß sie zufriedenstellende Leuchtergebnisse liefern. Nachteilig ist allerdings, daß das Austauschen der bekannten Leuchtmittel oftmals schwierig ist, außerdem ist häufig die Lebensdauer der bekannten Leuchtmittel nicht zufriedenstellend. Ein weiterer Nachteil besteht in der Brandgefahr, hervorgerufen durch die im Leuchtmittel erzeugte Wärme.The invention relates to a lamp with an electrical supply unit, a lamp body and a feed line from the supply unit to the lamp body. Various embodiments of such lights are known from the prior art. The luminaire bodies have conventional illuminants such as fluorescent tubes, halogen lights or the like, the voltage applied to the luminaire body being constant in the known luminaires. Such lights have the advantage that they provide satisfactory lighting results. A disadvantage, however, is that the known bulbs are often difficult to replace, and the life of the known bulbs is often unsatisfactory. Another disadvantage is the risk of fire, caused by the heat generated in the lamp.
Der Erfindung liegt die Aufgabe zugrunde, die bekannten Leuchten unter Beibehaltung der bisherigen Vorteile in der Weise zu verbessern, daß die Lebensdauer der Leuchtmittel verbessert wird, und eine bessere Austauschbarkeit der Leuchtmittel als bisher gewährleistet ist. Außerdem sollen die Funktionseigenschaften der Leuchte verbessert werden, insbesondere die mit der Brandgefahr einhergehenden Nachteile vermieden werden. Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Leuchtenkörper einen als Platine ausgebildeten Leuchtenkopf aufweist, wobei die Platine wenigstens eine Leuchtdiodenkette beinhaltet, und daß der in die Leuchtdiodenkette fließende Strom konstant ist.The invention has for its object to improve the known lights while maintaining the previous advantages in such a way that the life of the lamps is improved, and better interchangeability of the lamps is guaranteed than before. In addition, the functional properties of the luminaire are to be improved, in particular the disadvantages associated with the risk of fire are to be avoided. The object is achieved in that the lamp body has a lamp head designed as a circuit board, the circuit board containing at least one LED chain, and that the current flowing into the LED chain is constant.
Auf diese Weise wird mit einfachen Mitteln eine Leuchte geschaffen, deren Leuchtmittel eine längere Lebensdauer als bei den bekannten Leuchten aufweist, und deren Leuchtmittel in einfacher Weise ausgetauscht werden können. Die Anordnung weist außerdem durch die Verwendung der Platine mit der oder den Leuchtdiodenkette (n) den Vorteil auf, daß durch die Verwendung von Leuchtdioden, die sich bei ihrer Funktion an sich nicht wesentlich erhitzen, eine Verringerung der Brandgefahr erreicht wird. Hierdurch läßt sich der brandschutztechnisch vorgeschriebene Mindestabstand zwischen Leuchtmittel und zu beleuchtendem Objekt reduzieren. Im weiteren sind derartige Anordnungen flexibel gestaltbar, d.h. die Relativlage zwischen dem Leuchtmittel und der Versorgungseinheit ist variabel. Durch diese Flexibilität ergibt sich der besondere Vorteil, daß die Leuchte beispielsweise an einen Monitor angepaßt werden kann, um die darunter stehende Tastatur optimal zu beleuchten, ohne daß der Leuchtenfuß den Arbeitsbereich berührt.In this way, a luminaire is created with simple means, the illuminant of which has a longer lifespan than that of the known luminaires, and the illuminant of which can be replaced in a simple manner. The arrangement also has the advantage through the use of the circuit board with the light-emitting diode chain (s) that the use of light-emitting diodes, which do not heat up significantly in their function, reduces the risk of fire. In this way, the minimum distance between the illuminant and the object to be illuminated, which is required by fire protection, can be reduced. Furthermore, such arrangements can be designed flexibly, i.e. the relative position between the illuminant and the supply unit is variable. This flexibility results in the particular advantage that the lamp can be adapted to a monitor, for example, in order to optimally illuminate the keyboard underneath without the lamp base touching the work area.
Bei der bevorzugten Ausführungsform der vorliegenden Erfindung weist der als Platine ausgebildete Leuchtenkopf leicht lösbare elektrische Kontaktstellen auf. Dadurch wird die Austauschbarkeit der Platine zusätzlich unterstützt.In the preferred embodiment of the present invention, the lamp head designed as a circuit board has easily detachable electrical contact points. This also supports the interchangeability of the board.
Nach einem weiteren Merkmal der vorliegenden Erfindung ist vorgesehen, daß die Platine des Leuchtenkopfes mehrere, parallel geschaltete Leuchtdiodenketten aufweist. Auf diese Weise wird eine noch gleichmäßigere Leuchtfunktion erreicht.According to a further feature of the present invention, it is provided that the circuit board of the lamp head has a plurality of light-emitting diode chains connected in parallel having. In this way, an even more uniform lighting function is achieved.
Nach einem weiteren Merkmal der vorliegenden Erfindung ist vorgesehen, daß die elektrische Versorgungseinheit der Leuchte batteriebetrieben bzw. akkubetrieben ausgebildet ist. Auf diese Weise kann auf zusätzliche elektrische Zuleitungen zu der Versorgungseinheit verzichtet werden und die Positionierung der Leuchte auf dem Arbeitsplatz wird variabler.According to a further feature of the present invention, it is provided that the electrical supply unit of the lamp is battery-operated or battery-operated. In this way, additional electrical supply lines to the supply unit can be dispensed with and the positioning of the lamp on the workstation becomes more variable.
Die vorliegende Erfindung ist in den Figuren der Zeichnung in mehreren Ausführungsbeispielen dargestellt. Es zeigen:The present invention is shown in the figures of the drawing in several exemplary embodiments. Show it:
Fig. 1 eine stark vereinfachte schematische Prinzip- Darstellung der erfindungemäßen Leuchte,1 is a greatly simplified schematic principle representation of the lamp according to the invention,
Fig. 2 eine stark vereinfachte schematische Darstellung der Platine eines erfindungsgemäß ausgebildeten Leuchtenkopfes mit mehreren, parallel geschalteten LeuchtdiodenkettenFig. 2 is a highly simplified schematic representation of the circuit board of a lamp head designed according to the invention with a plurality of light-emitting diode chains connected in parallel
Die erfindungsgemäße Leuchte ist generell mit 10 bezeichnet. Sie weist, s. Fig. 1 der Zeichnung, eine elektrische Versorgungseinheit 11 auf, einen Leuchtenkörper 12 und eine Zuleitung 13 von der Versorgungseinheit 11 zu dem Leuchtenkörper 12. Der Leuchtenkörper 12 besteht aus einem eine Platine 15 aufweisenden Leuchtenkopf 14. Die Platine 15 weist dabei wenigstens eine Leuchtdiodenkette 16 auf. Außerdem ist der von der Versorgungseinheit 11 kommende, in die Platine 15 fließende, Strom konstant, dadurch, daß der Leuchtenkopf 14 elektrisch vor einer Konstantstromquelle beaufschlagt wird, die räumlich entweder in der Versorgungseinheit 11 oder im Leuchtenkörper 12 angeordnet ist.The lamp according to the invention is generally designated 10. She points, s. 1 of the drawing, an electrical supply unit 11, a lamp body 12 and a feed line 13 from the supply unit 11 to the lamp body 12. The lamp body 12 consists of a lamp head 14 having a circuit board 15. The circuit board 15 has at least one LED chain 16 on. In addition, the current coming from the supply unit 11 and flowing into the circuit board 15 is constant, in that the lamp head 14 is acted upon electrically in front of a constant current source which is spatially either in the Supply unit 11 or in the lamp body 12 is arranged.
Durch die Verwendung einer solchen Anordnung wird erreicht, daß die Lebensdauer der Leuchtmittel erheblich verlängert wird, und daß die als Platine mit Leuchtdioden ausgebildeten Leuchtmittel besser austauschbar sind. Diese Austauschbarkeit des als Platine 15 ausgebildeten Leuchtenkopfes 14 kann außerdem durch an der Platine 15 angeordnete, leicht lösbare elektrische Kontaktstellen 17 unterstützt werden.By using such an arrangement it is achieved that the lifespan of the illuminants is considerably extended and that the illuminants designed as a circuit board with light-emitting diodes are easier to replace. This interchangeability of the lamp head 14 designed as a circuit board 15 can also be supported by easily detachable electrical contact points 17 arranged on the circuit board 15.
Durch die Beaufschlagung der Platine 15 mit der Konstantstromquelle wird eine stabile Versorgung der Leuchtdiodenkette (n) 16 als Leuchtmittel gewährleistet. Auch ist eine Begrenzung des MaximalStromes möglich, da ansonsten die Leuchtdioden bei Überschreiten eines bestimmten Wertes zerstört werden. Da die Leuchtdioden im wesentlichen "kaltes Licht" ausstrahlen, wird die Brandgefahr verringert. Auch kann die Anordnung flexibel gestaltet werden, so daß der Mindestabstand des zu beleuchtenden Objektes zur Leuchte reduzierbar ist.By supplying the circuit board 15 with the constant current source, a stable supply of the light-emitting diode chain (s) 16 as a light source is ensured. It is also possible to limit the maximum current, otherwise the LEDs will be destroyed if a certain value is exceeded. Since the LEDs emit essentially "cold light", the risk of fire is reduced. The arrangement can also be designed flexibly, so that the minimum distance of the object to be illuminated from the lamp can be reduced.
Bei dem in der Fig. 2 der Zeichnung dargestellten Ausführungsbeispiel weist die Platine 15 des Leuchtenkopfes 14 mehrere, parallel geschaltete Leuchtdiodenketten 16 auf. Dadurch wird eine noch gleichmäßigere Beleuchtung erzielt. Die in der Fig. 1 der Zeichnung dargestellte elektrische Versorgungseinheit 11 der Leuchte 10 ist in dem dargestellten Ausführungsbeispiel batteriebetrieben ausgebildet, d.h. es kann auf zusätzliche elektrische Verbindungsmittel zu der Versorgungseinheit 11 verzichtet werden. In the embodiment shown in FIG. 2 of the drawing, the circuit board 15 of the lamp head 14 has a plurality of light-emitting diode chains 16 connected in parallel. This results in even more uniform lighting. The electrical supply unit 11 of the lamp 10 shown in FIG. 1 of the drawing is battery-operated in the exemplary embodiment shown, i.e. additional electrical connection means to the supply unit 11 can be dispensed with.
