Definitions
- the present invention relates to a lighting system for mounting and powering a plurality of lighting units.
- Trunking systems are used in a wide variety of applications, as they allow a flexible arrangement of different lighting units and can therefore be adapted to permanently installed individual lights in a simple manner to different circumstances individually.
- a light band system has an elongate support structure, in particular one or more mounting rails for mounting the lamp units, wherein simultaneously provided within or on the support structure power supply means for powering the lamp units.
- a known light band system of this type is sold by the applicant under the name Tecton .
- This light band system which, for example, in the WO 01/91249 A1 is characterized in that the lighting units can be arranged at an arbitrary position of the support structure, which is achieved by a special arrangement and storage of the lines for the power supply.
- the current conductors held in special so-called current-conducting profiles are accessible over the entire length of the supporting structure and, nevertheless, the effects arising due to temperature fluctuations are compensated with respect to different length expansions of the components of the continuous-row lighting system. Only through these special measures it is achieved that a luminaire unit can be positioned at any point.
- the lighting units can be arranged only at predetermined positions, these positions are each predetermined by corresponding contacting elements, which allow the lights to connect to the power supply. Since the luminaire units generally have standardized lengths, the contacting elements can be positioned in a coordinated manner on the support structure.
- luminaire units were used, which included fluorescent lamps as light sources. These luminaire units then usually had a so-called electronic ballast for operating the light sources, which provides the power supply voltage provided by the lighting system in a suitable operating voltage for the associated lamp (s). Since the length of a fluorescent lamp is in any case significantly greater than the length of an electronic ballast, the use of such a lamp operating device did not affect the design of the luminaire unit, in particular on its longitudinal dimension.
- LED-based light sources are being used in lighting technology.
- Such light sources can not be connected directly to the general supply voltage, which is for example in the range of 230 volts. Instead, they require a much lower, so-called low-voltage voltage in the range of 24 volts.
- Luminaire units with such LED light sources require a so-called converter unit, which converts the supply voltage provided by the light band system, which is generally a so-called high-voltage voltage, into the low-voltage voltage required to operate the LED light sources.
- the present invention has for its object to provide a novel solution for lighting systems, which makes it possible to arrange over a greater length away lighting units with LED light sources and to supply in a suitable manner with electricity.
- the solution according to the invention is based on the idea of providing the low-voltage supply voltage required for operating the luminaire units with LED light sources over a limited length of the support structure of a continuous-line system.
- converters are used which apply the low-voltage voltage to power supply lines over a certain section of the system.
- the lighting units with the LED light sources can then be flexibly connected to these supply lines, while the converters are in turn supplied with power via separate lines.
- the luminaire units do not require their own converter in this solution and can therefore be made compact or their length individually.
- the core idea of the present invention is thus that there is a combination of high-voltage supply and low-voltage supply, which ultimately allows the connection of lighting units with LED light sources to the lighting system.
- a plurality of second power supply circuits are formed, which are each connected via an associated converter unit with the first power supply circuit.
- the arranged at certain intervals converter units are then connected to each other via the common high-voltage supply and provide in sections each required for the operation of the lighting units low-voltage.
- the second power supply circuits abut each other at their ends and extend in their entirety substantially over the entire length of the support structure.
- the second circuits may also be connected together at their ends. This ultimately creates the possibility that the luminaire units can be positioned substantially freely over the entire length of the support structure. This is particularly advantageous because now - due to the compact dimensions of the LED light sources - the lighting units no longer need longer standard lengths but instead can be dimensioned differently. In this case, the advantage of a flexible arrangement is particularly important.
- the lines of the second power supply circuits are arranged freely accessible from a mounting side of the support structure ago. This facilitates the flexible placement and connection of the lighting units to the second power supply circuit (s). Since a low voltage is applied to the corresponding lines, no special protective measures are provided in comparison to the lines of the first power supply circuit, by which an accidental contact with the lines is prevented.
- the power supply of the converter units as already mentioned by the first power supply circuit.
- the lines of the first power supply circuit have contacting means for connecting a converter unit at predetermined intervals.
- the positions for the converter units are predetermined and are preferably selected such that the associated second power supply circuits have a length at which the losses occurring are not too high.
- the lines of the first power supply circuit are formed and stored so that they allow a substantially free arrangement of the converter units.
- the design of the above-mentioned lighting system Tecton could be made of the design of the above-mentioned lighting system Tecton .
- the support structure of the light band system according to the invention is preferably formed by one or more substantially U-shaped support rails. It can then be provided that the lines of the first power supply circuit extend within the mounting rail.
- the lines of the second power supply circuits are preferably arranged in the vicinity of the opening of the support rail, since in this case the contact is facilitated by the lighting units.
- further second power supply circuits are arranged on the side facing away from the opening of the mounting rail side. In this area of the support structure then, for example, additional lighting units could be arranged, which are used to realize an indirect lighting.
- the converter units are preferably arranged in the middle of the associated second power supply circuit, viewed in the longitudinal direction of the lighting band system. However, it would also be conceivable that the converter units are arranged in the middle of two adjacent power supply circuits and are connected to both second circuits. A converter unit can then be used in this case to provide a low-voltage over a length of about 4 to 8 meters away.
- first power supply circuit I to which a high-voltage supply voltage (HV) is applied
- said first power supply circuit I preferably extends over the entire length of the support structure of the lighting system 1 away.
- the support structure consists of several joined together and interconnected mounting rails.
- the second power supply circuits II are each supplied via a converter unit.
- the converter unit thus assumes the coupling between the first power supply circuit I and the power supply circuit circuit II and, in particular, converts the high-voltage HV of the first power supply circuit I into the suitable low-voltage voltage NV.
- so-called low-voltage groups are formed over a limited length, that is, all luminaire units which are connected to the corresponding second power supply circuit II of such NV group are locally powered by a common converter unit with power.
- the entirety of the second power supply circuits II does not necessarily have to cover the complete lighting system or the first power supply circuit I.
- luminaire units with LED light sources should be arranged only in a partial area of the light band system, whereas the remaining area of the light band system is used by high-voltage luminaire units.
- the second power supply circuits II according to the invention can be formed only in the corresponding sections, and in particular it would also be conceivable to realize only a single second power supply circuit II in the lighting strip system.
- the first power supply circuit I also does not necessarily have to extend over the entire length of the support structure.
- FIG. 1 shows first in the upper area a first variant for the arrangement of the second power supply circuits II, in which the individual low-voltage groups are separated from each other and each have a length corresponding to a single rail length of the support structure.
- each individual rail is assigned a converter unit which supplies the associated low-voltage group or the associated second power supply circuit II.
- the corresponding second power supply circuits II can - as shown - be separated from each other and the front side adjacent to each other or be connected to each other at their ends.
- a second variant is shown in which two so-called extended low-voltage groups are used.
- the associated converter unit is arranged at the transition between two adjacent low-voltage groups and supplies both with the required low-voltage supply voltage, whereby a greater length for the extended low-voltage group is achieved.
- This principle was applied again in the third, lower variant, although the length of the extended low-voltage group can not be arbitrarily increased, otherwise the line losses would increase again.
- the length of a low-voltage group can also depend, inter alia, which or how many luminaire units are to be arranged on the second power supply circuit. Realistic are lengths in the range of 4m to 8m, and in the case where one converter supplies two adjacent power circuits II, a length for an extended low-voltage group in the range of up to 16m can be achieved.
- the core idea of the invention is thus that converter units are connected to the first power supply circuit extending essentially over the entire or a greater length of the light band system and then supply local areas with the low-voltage voltage, whereby second power supply circuits limited in their length are formed which then the lighting units are connected.
- FIG. 2 a sectional view of a first embodiment of a lighting strip system 1 according to the invention, in which case the first power supply circuit I is formed by cables 10, 11 which extend in the present case at the top of a support rail 2.
- the arrangement of the cables 10, 11 can also be designed differently.
- the first power supply circuit I also consist of significantly more cables, for example to enable a phase selection and / or the transmission of control signals, as is known from trunking systems.
- the support rail 2 is designed substantially U-shaped and open to the bottom to allow the attachment of lighting units 100.
- These are, in particular, luminaire units 100 in which LED light sources 105 are used and which, accordingly, require a low-voltage voltage.
- This low-voltage is now provided by the fact that converter units 20 are arranged at regular intervals of the light band system 1 and connected to the first power supply circuit I. For example, at certain positions of the lighting system 1 contact elements 12 may be provided, with which the converter units 20 are coupled to be supplied via the first power supply circuit I with power.
- a converter unit 20 itself then converts the high-voltage voltage of the first power supply circuit I into a low-voltage voltage and makes it available via lines 15, 16, which form the second power supply circuit II.
- the luminaire units 100 can then be connected to this second power supply circuit II, on the one hand contacting the lines 15, 16 and, on the other hand, being mechanically fastened to the mounting rail 2.
- the converter units 20 are arranged at specific intervals and respectively supply locally associated luminaire units 100 over a certain area, which then form the associated low-voltage group.
- the arrangement of the converter units 20 and of the second power supply circuits II is preferably such that the lighting units 100 can be arranged substantially over the entire length of the light band system 1. That is, the entirety of the second power supply circuits II preferably covers substantially the entire length of the light band system 1, wherein - as mentioned above - the second power supply circuits II may be provided only in certain sections.
- second power supply circuits II and II ' can also be formed on both sides of the support rail 2, which allow the additional arrangement of additional lighting units 100.
- FIG. 3 A further education of in FIG. 2 shown light band system is in FIG. 3 shown.
- so-called Stromleitprofile 13, 14 are arranged for storage of lines of the first power supply circuit I for the power supply and signal transmission within an upper receiving area of the support rail.
- These Stromleitprofilen 13, 14 are plastic parts through which open to the interior of the support rail 2 grooves are formed in which a storage of the lines.
- Such a technology is for example from the already mentioned lighting system Tecton or the WO 01/91249 A1 known, which brings with it the particular advantage that the lines of the first power supply circuit I over the entire length of the lighting system 1 are contactable away.
- a corresponding converter unit is in FIG. 4 and has an elongated housing 21, in which in particular the means for implementing the high-voltage voltage are arranged in the low-voltage.
- On the underside of the housing two lateral pivoting levers 22, 23 are arranged, via which a mechanical locking on the support rail 2 is achieved.
- one of the two pivot levers 22 also has a contacting element 24 in the form of a so-called rotary handle 24, via which two contacts 25, 26 are laterally swung out.
- the contacts 24, 25 are swung laterally so that they engage in the grooves of the Stromleitprofile 13,14 and reach against the corresponding lines of the first power supply circuit I in Appendix.
- the converter unit 20 is supplied with power.
- the rotary handle 24 is designed such that at least one of the contacts 25, 26 is adjustable, in particular height-adjustable, so that a phase selection is possible.
- the converter unit 20 also has a plug 27, which is connected via a flexible line 28 to the housing 21.
- the connection of the converter unit 20 with the lines 15, 16 of the second power supply circuit II then takes place via this plug 27.
- the flexible connecting line 27 facilitates the connection of the plug 27, via which the low-voltage voltage is ultimately made available, to the lines of the second power supply circuit II. If the converter unit 20 supplies two adjacent low-voltage groups, then the plug 27 can also be designed as a corresponding bridge.
- the lines 15, 16 of the second power supply circuit II compared to the lines of the first power supply circuit I and the Stromleitprofilen 13, 14 are arranged in the region of the opening of the support rail 2 and accordingly more easily accessible. This is possible because in the voltage applied to the lines of the second power supply circuit II low voltage no special measures must be taken, which prevent accidental contact with these lines 15, 16. In contrast, corresponding protective measures in the lines of the first power supply circuit I are absolutely necessary, which is why these lines preferably extend inside the support rail 2. Accordingly, contacting of the lines of the second power supply circuit II by the luminaire units 100 can be effected in a simple manner by a plug-in contact 101, which, as in FIG FIG. 5 is shown laterally arranged.
- the converter units 20 are arranged at regular intervals on the light-band system 1 and supply the respective surrounding area with the low-voltage voltage.
- other lighting units 150 which require a high-voltage power supply for operation.
- These high-voltage lighting units 150 which may be, for example, emergency lights to ensure an emergency lighting, are used in the same manner as the converter units 20 in the support rail 2 and have contacting elements with those in the Stromleitprofilen 13 and 14 extending lines of the first power supply circuit I can be contacted.
- a more flexible arrangement of different luminaire units 100, 150 is possible again.
- FIG. 6 shows a third variant of a lighting system 1, which on the variant of Figures 3-5 based.
- second lines 15 'and 16' or 15 "and 16" extend in the upper part of the mounting rail, over which further second power supply circuits II 'and II "or corresponding low-voltage groups are formed of the lighting system 1, therefore, further lighting units 100 can now be connected, which can now be used to realize an indirect lighting Support rails 2 are then provided with corresponding openings or apertures in order to enable the connection of a converter unit 20 to the lines of the additional second upper power supply circuits II ', II ". Again, it is also possible to connect high-voltage lighting units 150 as well.
- a converter unit 20 supplies two low-voltage groups arranged on the underside of the support rail 2 and, in addition, a further low-voltage group on the upper side for indirect lighting. Adjacent thereto are extended low-voltage groups formed on the underside and the top of the support rail 2, wherein additionally a high-voltage lighting module is connected to the support rail 2. It does not necessarily have to be a luminaire module. Instead, it could also be a sensor unit, for example a brightness or motion sensor, via which information about the automated control of the individual luminaire units can be obtained.
- the solution according to the invention thus creates the possibility of flexibly connecting lighting units which require a low-voltage voltage to a lighting strip system.
- the solution is characterized in particular by the fact that existing lighting systems can be expanded without much effort to allow the connection of such lighting units, which include, for example, LED light sources, without each luminaire unit must contain its own converter ,
Description
Die vorliegende Erfindung betrifft ein Lichtbandsystem zur Halterung und Stromversorgung mehrerer Leuchten-Einheiten.The present invention relates to a lighting system for mounting and powering a plurality of lighting units.
Lichtbandsysteme kommen in verschiedensten Anwendungsfällen zum Einsatz, da sie eine flexible Anordnung auch unterschiedlicher Leuchten-Einheiten ermöglichen und dementsprechend gegenüber fest installierten Einzelleuchten in einfacher Weise an unterschiedliche Gegebenheiten individuell angepasst werden können. Üblicherweise weist ein Lichtbandsystem eine längliche Tragstruktur, insbesondere ein oder mehrere Tragschienen zur Halterung der Leuchten-Einheiten auf, wobei gleichzeitig innerhalb bzw. an der Tragstruktur Stromversorgungsmittel zur Stromversorgung der Leuchten-Einheiten vorgesehen sind.Trunking systems are used in a wide variety of applications, as they allow a flexible arrangement of different lighting units and can therefore be adapted to permanently installed individual lights in a simple manner to different circumstances individually. Usually, a light band system has an elongate support structure, in particular one or more mounting rails for mounting the lamp units, wherein simultaneously provided within or on the support structure power supply means for powering the lamp units.
Ein bekanntes Lichtbandsystem dieser Art wird von der Anmelderin unter der Bezeichnung Tecton vertrieben. Dieses Lichtbandsystem, welches beispielsweise in der
Darüber hinaus sind allerdings auch Lichtbandsysteme bekannt, bei denen die Leuchten-Einheiten lediglich an vorgegebenen Positionen angeordnet werden können, wobei diese Positionen jeweils durch entsprechende Kontaktierungselemente, welche ein Anschließen der Leuchten an die Stromversorgung ermöglichen, vorgegeben sind. Da die Leuchten-Einheiten in der Regel standardisierte Längen aufweisen, können die Kontaktierungselemente darauf abgestimmt an der Tragstruktur positioniert werden.In addition, however, also lighting systems are known in which the lighting units can be arranged only at predetermined positions, these positions are each predetermined by corresponding contacting elements, which allow the lights to connect to the power supply. Since the luminaire units generally have standardized lengths, the contacting elements can be positioned in a coordinated manner on the support structure.
Bei den früheren Lichtbandsystemen kamen in der Regel Leuchten-Einheiten zum Einsatz, welche Leuchtstofflampen als Lichtquellen beinhalteten. Diese Leuchten-Einheiten wiesen dann üblicherweise ein sogenanntes elektronisches Vorschaltgerät zum Betreiben der Lichtquellen auf, welches die von dem Lichtbandsystem zur Verfügung gestellte Netzversorgungs-Spannung in eine geeignete Betriebsspannung für die zugehörige(n) Lampe(n) umsetzte. Da die Länge einer Leuchtstofflampe ohnehin deutlich größer ist als die Länge eines elektronischen Vorschaltgeräts, wirkte sich der Einsatz eines derartigen Lampenbetriebsgeräts nicht auf die Ausgestaltung der Leuchten-Einheit, insbesondere auf deren Längsabmessung aus.In the earlier lighting systems usually luminaire units were used, which included fluorescent lamps as light sources. These luminaire units then usually had a so-called electronic ballast for operating the light sources, which provides the power supply voltage provided by the lighting system in a suitable operating voltage for the associated lamp (s). Since the length of a fluorescent lamp is in any case significantly greater than the length of an electronic ballast, the use of such a lamp operating device did not affect the design of the luminaire unit, in particular on its longitudinal dimension.
Zwischenzeitlich kommen allerdings in der Beleuchtungstechnologie mehr und mehr Lichtquellen auf LED-Basis zum Einsatz. Derartige Lichtquellen können nicht unmittelbar an die allgemeine Versorgungsspannung, die beispielsweise im Bereich von 230 Volt liegt, angeschlossen werden. Stattdessen benötigen sie eine deutlich niedrigere, sogenannte Niedervoltspannung etwa im Bereich von 24 Volt. Leuchten-Einheiten mit derartigen LED-Lichtquellen benötigen also wiederum eine sogenannte Konvertereinheit, welche die von dem Lichtbandsystem zur Verfügung gestellte Versorgungsspannung, bei der es sich in der Regel um eine sogenannte Hochvoltspannung handelt, in die zum Betrieb der LED-Lichtquellen erforderliche Niedervoltspannung umsetzt.In the meantime, however, more and more LED-based light sources are being used in lighting technology. Such light sources can not be connected directly to the general supply voltage, which is for example in the range of 230 volts. Instead, they require a much lower, so-called low-voltage voltage in the range of 24 volts. Luminaire units with such LED light sources, in turn, require a so-called converter unit, which converts the supply voltage provided by the light band system, which is generally a so-called high-voltage voltage, into the low-voltage voltage required to operate the LED light sources.
Da allerdings LED-Lichtquellen nahezu punktförmig sind, wird die Länge einer derartigen Leuchten-Einheit, welche ein oder mehrere LED-Lichtquellen sowie eine Konvertereinheit aufweist, nunmehr maßgeblich durch die Abmessungen der Konvertereinheit beeinflusst. Dies bedeutet, dass Leuchten-Einheiten mit LED-Lichtquellen, die zur Verwendung bei den bekannten Lichtbandsystemen vorgesehen sind, eine gewisse Mindestlänge aufweisen. Hierdurch wird allerdings die Flexibilität bei der Nutzung von LED-Lichtquellen in Lichtbandsystemen stark eingeschränkt.However, since LED light sources are almost punctiform, the length of such a luminaire unit, which has one or more LED light sources and a converter unit, now significantly influenced by the dimensions of the converter unit. This means that luminaire units with LED light sources, which are intended for use in the known light-band systems, have a certain minimum length. However, this greatly limits the flexibility of using LED light sources in continuous row lighting systems.
Naheliegend wäre es auf den ersten Blick, auf den Leitungen zur Stromversorgung des Lichtbandsystems bereits die für den Betrieb der LED-Lichtquellen erforderliche Niedervoltspannung zur Verfügung zu stellen. Bei einer derartigen niedrigen Spannung sind allerdings die Verluste in den Stromleitungen verhältnismäßig hoch, sodass auf diesem Weg nur sehr kurze Lichtbandsysteme realisiert werden können.It would be obvious at first glance to already provide the low-voltage required for the operation of the LED light sources on the lines for powering the lighting system. At such a low voltage, however, the losses in the power lines are relatively high, so that in this way only very short light band systems can be realized.
Des Weiteren sind ähnliche Lichtbandsysteme bzw. ähnliche Leuchtanordnungen auch aus der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine neuartige Lösung für Lichtbandsysteme anzugeben, die es ermöglicht, auch über eine größere Länge hinweg Leuchten-Einheiten mit LED-Lichtquellen anzuordnen und in geeigneter Weise mit Strom zu versorgen.The present invention has for its object to provide a novel solution for lighting systems, which makes it possible to arrange over a greater length away lighting units with LED light sources and to supply in a suitable manner with electricity.
Die Aufgabe wird durch ein Lichtbandsystem zur Halterung und Stromversorgung mehrerer Leuchten-Einheiten mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a lighting system for mounting and power supply several lamp units with the features of
Die erfindungsgemäße Lösung beruht auf dem Gedanken, jeweils über eine begrenzte Länge der Tragstruktur eines Lichtbandsystems hinweg die zum Betrieb der Leuchten-Einheiten mit LED-Lichtquellen erforderliche Niedervoltversorgungsspannung zur Verfügung zu stellen. Hierfür werden Konverter eingesetzt, die jeweils über einen bestimmten Abschnitt des Systems hinweg die Niedervoltspannung an Stromversorgungleitungen anlegen. An diese Versorgungsleitungen können dann die Leuchten-Einheiten mit den LED-Lichtquellen flexibel angeschlossen werden, die Konverter wiederum werden über separate Leitungen mit Strom versorgt. Die Leuchten-Einheiten benötigen bei dieser Lösung keinen eigenen Konverter mehr und können dementsprechend kompakt bzw. in ihrer Länge individuell ausgestaltet werden.The solution according to the invention is based on the idea of providing the low-voltage supply voltage required for operating the luminaire units with LED light sources over a limited length of the support structure of a continuous-line system. For this purpose, converters are used which apply the low-voltage voltage to power supply lines over a certain section of the system. The lighting units with the LED light sources can then be flexibly connected to these supply lines, while the converters are in turn supplied with power via separate lines. The luminaire units do not require their own converter in this solution and can therefore be made compact or their length individually.
Erfindungsgemäß wird dementsprechend ein Lichtbandsystem zur Halterung und Stromversorgung von Leuchten-Einheiten vorgeschlagen, wobei das System aufweist:
- eine längliche Tragstruktur, insbesondere mindestens eine Tragschiene, zur Halterung der Leuchten-Einheiten, sowie
- sich entlang der Tragstruktur erstreckende Stromversorgungsmittel für die Stromversorgung der Leuchten-Einheiten, wobei die Stromversorgungsmittel aufweisen:
- ∘ erste sich vorzugsweise im Wesentlichen über die gesamte Länge der Tragstruktur erstreckende Leitungen, welche einen ersten Stromversorgungskreis bilden,
- ∘ zweite Leitungen, welche sich über eine Teillänge der Tragstruktur bzw. des ersten Stromversorgungskreises erstrecken und einen zweiten Stromversorgungskreis bilden, der zur elektrischen Kontaktierung durch die Leuchten-Einheiten vorgesehen ist, derart, dass die Leuchten-Einheiten frei über die gesamte Länge des zweiten Stromversorgungskreises angeordnet und angeschlossen werden können,
- an elongated support structure, in particular at least one support rail, for holding the luminaire units, as well as
- power supply means extending along the support structure for the power supply of the lighting units, the power supply means comprising:
- ∘ first preferably substantially over the entire length of the support structure extending lines, which form a first power supply circuit,
- ∘ second lines, which extend over a partial length of the support structure and the first power supply circuit and form a second power supply circuit, which is provided for electrical contacting by the lamp units, such that the lighting units free over the entire length of the second power supply circuit can be arranged and connected,
Kerngedanke der vorliegenden Erfindung ist also, dass eine Kombination aus Hochvolt-Versorgung und Niedervolt-Versorgung vorliegt, welche letztendlich dass Anschließen von Leuchten-Einheiten mit LED-Lichtquellen an das Lichtbandsystem ermöglicht.The core idea of the present invention is thus that there is a combination of high-voltage supply and low-voltage supply, which ultimately allows the connection of lighting units with LED light sources to the lighting system.
Vorzugsweise sind in dem erfindungsgemäßen Lichtbandsystem mehrere zweite Stromversorgungskreise ausgebildet, welche jeweils über eine zugehörige Konvertereinheit mit dem ersten Stromversorgungskreis verbunden sind. Die in gewissen Abständen angeordneten Konvertereinheiten sind dann über die gemeinsame Hochvolt-Versorgung miteinander verbunden und stellen abschnittsweise jeweils die zum Betrieb der Leuchten-Einheiten erforderliche Niedervoltspannung zur Verfügung. Dabei ist vorzugsweise vorgesehen, dass die zweiten Stromversorgungkreise jeweils an Ihren Enden aneinander stoßen und sich in ihrer Gesamtheit im Wesentlichen über die gesamte Länge der Tragstruktur erstrecken. Beispielsweise können die zweiten Stromkreise an ihren Enden auch miteinander verbunden sein. Hierdurch wird letztendlich die Möglichkeit geschaffen, dass die Leuchten-Einheiten im Wesentlichen frei über die gesamte Länge der Tragstruktur hinweg positioniert werden können. Dies ist insbesondere von Vorteil, da nunmehr - aufgrund der kompakten Abmessungen der LED-Lichtquellen - die Leuchten-Einheiten keine Standardlängen mehr aufweisen müssen sondern stattdessen unterschiedlich dimensioniert werden können. In diesem Fall kommt der Vorteil einer flexiblen Anordnung besonders zum Tragen.Preferably, in the lighting strip system according to the invention a plurality of second power supply circuits are formed, which are each connected via an associated converter unit with the first power supply circuit. The arranged at certain intervals converter units are then connected to each other via the common high-voltage supply and provide in sections each required for the operation of the lighting units low-voltage. It is preferably provided that the second power supply circuits abut each other at their ends and extend in their entirety substantially over the entire length of the support structure. For example, the second circuits may also be connected together at their ends. This ultimately creates the possibility that the luminaire units can be positioned substantially freely over the entire length of the support structure. This is particularly advantageous because now - due to the compact dimensions of the LED light sources - the lighting units no longer need longer standard lengths but instead can be dimensioned differently. In this case, the advantage of a flexible arrangement is particularly important.
Vorzugsweise sind die Leitungen des bzw. der zweiten Stromversorgungskreise von einer Montageseite der Tragstruktur her frei zugänglich angeordnet. Hierdurch wird das flexible Anordnen und Anschließen der Leuchten-Einheiten an den bzw. die zweiten Stromversorgungskreise erleichtert. Da an den entsprechenden Leitungen eine Niedervoltspannung anliegt, sind auch im Vergleich zu den Leitungen des ersten Stromversorgungskreises keine besonderen Schutzmaßnahmen vorzusehen, durch welche ein versehentliches Berühren der Leitungen verhindert wird.Preferably, the lines of the second power supply circuits or are arranged freely accessible from a mounting side of the support structure ago. This facilitates the flexible placement and connection of the lighting units to the second power supply circuit (s). Since a low voltage is applied to the corresponding lines, no special protective measures are provided in comparison to the lines of the first power supply circuit, by which an accidental contact with the lines is prevented.
Die Stromversorgung der Konvertereinheiten erfolgt wie bereits erwähnt durch den ersten Stromversorgungskreis. Hierbei kann gemäß einem ersten Ausführungsbeispiel vorgesehen sein, dass die Leitungen des ersten Stromversorgungskreises in vorgegebenen Abständen Kontaktierungsmittel zum Anschließen einer Konvertereinheit aufweisen. In diesem Fall sind die Positionen für die Konvertereinheiten vorgegeben und werden vorzugsweise derart gewählt, dass die zugehörigen zweiten Stromversorgungskreise eine Länge aufweisen, bei der die auftretenden Verluste nicht zu hoch sind. Alternativ hierzu könnte allerdings auch vorgesehen sein, dass die Leitungen des ersten Stromversorgungskreises derart ausgebildet und gelagert sind, dass sie eine im Wesentlichen freie Anordnung der Konvertereinheiten ermöglichen. Hierfür könnte beispielsweise auf die Ausgestaltung des bereits erwähnten Lichtbandsystems Tecton zurückgegriffen werden.The power supply of the converter units as already mentioned by the first power supply circuit. In this case, it can be provided according to a first exemplary embodiment that the lines of the first power supply circuit have contacting means for connecting a converter unit at predetermined intervals. In this case, the positions for the converter units are predetermined and are preferably selected such that the associated second power supply circuits have a length at which the losses occurring are not too high. Alternatively, however, could also be provided that the lines of the first power supply circuit are formed and stored so that they allow a substantially free arrangement of the converter units. For this purpose, for example, could be made of the design of the above-mentioned lighting system Tecton .
Die Tragstruktur des erfindungsgemäßen Lichtbandsystems wird vorzugsweise durch eine oder mehrere im Wesentlichen U-förmige Tragschienen gebildet. Hierbei kann dann vorgesehen sein, dass die Leitungen des ersten Stromversorgungskreises innerhalb der Tragschiene verlaufen. Die Leitungen des bzw. der zweiten Stromversorgungskreise sind hingegen vorzugsweise in der Nähe der Öffnung der Tragschiene angeordnet, da hierbei das Kontaktieren durch die Leuchten-Einheiten erleichtert wird. Ferner kann ergänzend auch vorgesehen sein, dass an der der Öffnung der Tragschiene abgewandten Seite weitere zweite Stromversorgungskreise angeordnet sind. In diesem Bereich der Tragstruktur könnten dann beispielsweise zusätzliche Leuchten-Einheiten angeordnet werden, welche zur Realisierung einer Indirektbeleuchtung genutzt werden.The support structure of the light band system according to the invention is preferably formed by one or more substantially U-shaped support rails. It can then be provided that the lines of the first power supply circuit extend within the mounting rail. The lines of the second power supply circuits, however, are preferably arranged in the vicinity of the opening of the support rail, since in this case the contact is facilitated by the lighting units. Furthermore, it can also be provided in addition that further second power supply circuits are arranged on the side facing away from the opening of the mounting rail side. In this area of the support structure then, for example, additional lighting units could be arranged, which are used to realize an indirect lighting.
Die Konvertereinheiten sind - in Längsrichtung des Lichtbandsystems gesehen - vorzugsweise in der Mitte des zugehörigen zweiten Stromversorgungskreises angeordnet. Denkbar wäre allerdings auch, dass die Konvertereinheiten in der Mitte zweier benachbarter Stromversorgungskreise angeordnet sind und mit beiden zweiten Stromkreisen verbunden sind. Eine Konvertereinheit kann in diesem Fall dann dazu genutzt werden, eine Niedervoltspannung über eine Länge von etwa 4 bis 8 Metern hinweg zur Verfügung zu stellen.The converter units are preferably arranged in the middle of the associated second power supply circuit, viewed in the longitudinal direction of the lighting band system. However, it would also be conceivable that the converter units are arranged in the middle of two adjacent power supply circuits and are connected to both second circuits. A converter unit can then be used in this case to provide a low-voltage over a length of about 4 to 8 meters away.

Der der vorliegenden Erfindung zugrunde liegende Gedanke soll zunächst anhand der schematischen Darstellung von
Hierbei sind schematisch untereinander drei Lichtbandsysteme dargestellt, welche zunächst jeweils einen ersten Stromversorgungskreis I aufweisen, an dem eine Hochvolt-Versorgungsspannung (HV) anliegt, wobei sich dieser erste Stromversorgungskreis I vorzugsweise über die gesamte Länge der Tragstruktur des Lichtbandsystems 1 hinweg erstreckt. Üblicherweise besteht die Tragstruktur aus mehreren aneinandergefügten und miteinander verbundenen Tragschienen.Here, three light band systems are schematically shown with each other, which first each have a first power supply circuit I, to which a high-voltage supply voltage (HV) is applied, said first power supply circuit I preferably extends over the entire length of the support structure of the
Sollen an dieses Lichtbandsystem 1 Leuchten-Einheiten angeschlossen werden, welche eine Niedervolt-Versorgungsspannung (NV) benötigen, so besteht nunmehr das Problem, dass diese Niedervoltspannung nicht an Leitungen des ersten, sich über das gesamte Lichtbandsystem bzw. zumindest über eine größere Länge hinweg erstreckenden Stromkreis I angelegt werden kann, da die sich hierbei ergebenden Verluste über die gesamte Länge des ersten Stromkreises I zu hoch wären.If lighting units are to be connected to this lighting system, which require a low-voltage supply voltage (NV), then there is the problem that this low-voltage not on lines of the first, over the entire lighting system or at least over a greater length extending Circuit I can be applied, since the resulting losses over the entire length of the first circuit I would be too high.
Erfindungsgemäß werden deshalb zusätzliche zweite Stromkreise II gebildet, an denen jeweils die gewünschte Niedervoltspannung anliegt und welche sich jeweils lediglich über einen Teil des Lichtbandsystems bzw. des ersten Stromkreises I hinweg erstrecken, wobei die zweiten Stromversorgungskreise II jeweils über eine Konvertereinheit versorgt werden. Die Konvertereinheit übernimmt also die Kopplung zwischen erstem Stromversorgungskreis I und Stromversorgungskreis Stromkreis II und setzt insbesondere die Hochvoltspannung HV des ersten Stromversorgungskreises I in die geeignete Niedervoltspannung NV um. Auf diese Weise werden über eine begrenzte Länge hinweg jeweils sogenannte Niedervolt-Gruppen gebildet, das heißt, alle Leuchten-Einheiten, welche an den entsprechenden zweiten Stromversorgungskreis II einer derartigen NV-Gruppe angeschlossen werden, werden lokal von einer gemeinsamen Konvertereinheit mit Strom versorgt. Diese zweiten Stromversorgungskreise II weisen nunmehr allerdings - wie bereits erwähnt - lediglich eine begrenzte Länge auf, die derart bemessen ist, dass die sich ergebenden Leitungsverluste nicht zu hoch werden. Dadurch, dass mehrere zweite Stromversorgungskreise II aneinander angrenzend angeordnet werden, besteht allerdings wiederum die Möglichkeit, über die gesamte Länge des Lichtbandsystems 1 hinweg Leuchten-Einheiten, welche die Niedervoltspannung benötigen, anzuschließen.According to the invention therefore additional second circuits II are formed, each of which bears the desired low-voltage and each extending only over part of the lighting system or the first circuit I away, the second power supply circuits II are each supplied via a converter unit. The converter unit thus assumes the coupling between the first power supply circuit I and the power supply circuit circuit II and, in particular, converts the high-voltage HV of the first power supply circuit I into the suitable low-voltage voltage NV. In this way, so-called low-voltage groups are formed over a limited length, that is, all luminaire units which are connected to the corresponding second power supply circuit II of such NV group are locally powered by a common converter unit with power. However, these second power supply circuits II now - as already mentioned - only a limited length, which is dimensioned such that the resulting line losses are not too high. The fact that several second power supply circuits II are arranged adjacent to each other, however, in turn, it is possible to connect over the entire length of the
An dieser Stelle soll allerdings ausdrücklich darauf hingewiesen werden, dass die Gesamtheit der zweiten Stromversorgungskreise II nicht zwingend das vollständige Lichtbandsystem bzw. den ersten Stromversorgungskreis I abdecken muss. Beispielsweise wäre es durchaus denkbar, dass Leuchten-Einheiten mit LED-Lichtquellen lediglich in einem Teilbereich des Lichtbandsystems angeordnet werden sollen, während hingegen der restliche Bereich des Lichtbandsystems von Hochvolt-Leuchten-Einheiten genutzt wird. In diesem Fall können die erfindungsgemäßen zweiten Stromversorgungskreise II nur in den entsprechenden Abschnitten ausgebildet werden, wobei insbesondere auch denkbar wäre, in dem Lichtbandsystem lediglich einen einzigen zweiten Stromversorgungskreis II zu realisieren. Ferner muss sich der erste Stromversorgungskreis I auch nicht zwingend über die gesamte Länge der Tragstruktur erstrecken.At this point, however, it should be expressly pointed out that the entirety of the second power supply circuits II does not necessarily have to cover the complete lighting system or the first power supply circuit I. For example, it would certainly be conceivable that luminaire units with LED light sources should be arranged only in a partial area of the light band system, whereas the remaining area of the light band system is used by high-voltage luminaire units. In this case, the second power supply circuits II according to the invention can be formed only in the corresponding sections, and in particular it would also be conceivable to realize only a single second power supply circuit II in the lighting strip system. Furthermore, the first power supply circuit I also does not necessarily have to extend over the entire length of the support structure.
Kerngedanke der Erfindung ist also, dass Konvertereinheiten an den sich im Wesentlichen über die gesamte bzw. eine größere Länge des Lichtbandsystems erstreckenden ersten Stromversorgungskreis angeschlossen werden und dann jeweils lokale Bereiche mit der Niedervoltspannung versorgen, wodurch zweite, in ihrer Länge begrenzte Stromversorgungskreise gebildet werden, an welche dann die Leuchten-Einheiten angeschlossen werden. Hierbei bestehen unterschiedliche Möglichkeiten zur Realisierung dieses Gedankens, welche nachfolgend anhand der weiteren Figuren erläutert werden.The core idea of the invention is thus that converter units are connected to the first power supply circuit extending essentially over the entire or a greater length of the light band system and then supply local areas with the low-voltage voltage, whereby second power supply circuits limited in their length are formed which then the lighting units are connected. There are different possibilities for the realization of this idea, which will be explained below with reference to the further figures.
Die Tragschiene 2 ist im Wesentlichen U-förmig ausgestaltet und zur Unterseite hin geöffnet um das Ansetzen von Leuchten-Einheiten 100 zu ermöglichen. Hierbei handelt es sich insbesondere um Leuchten-Einheiten 100, bei denen LED-Lichtquellen 105 zum Einsatz kommen und welche dementsprechend eine Niedervoltspannung benötigen. Diese Niedervoltspannung wird nunmehr dadurch zur Verfügung gestellt, dass in regelmäßigen Abständen des Lichtbandsystems 1 Konvertereinheiten 20 angeordnet und an den ersten Stromversorgungskreis I angeschlossen werden. Beispielsweise könnten an bestimmten Positionen des Lichtbandsystems 1 Kontaktelemente 12 vorgesehen sein, mit welchen die Konvertereinheiten 20 gekoppelt werden, um über den ersten Stromversorgungskreis I mit Strom versorgt zu werden.The
Eine Konvertereinheit 20 selbst setzt dann die Hochvoltspannung des ersten Stromversorgungskreises I in eine Niedervoltspannung um und stellt diese über Leitungen 15, 16 zur Verfügung, welche den zweiten Stromversorgungskreis II bilden. An diesen zweiten Stromversorgungskreis II können dann die Leuchten-Einheiten 100 angeschlossen werden, wobei sie einerseits die Leitungen 15, 16 kontaktieren und andererseits mechanisch an der Tragschiene 2 befestigt werden.A
Wie bereits erwähnt sind die Konvertereinheiten 20 in bestimmten Abständen angeordnet und versorgen jeweils lokal über einen bestimmten Bereich hinweg zugehörige Leuchten-Einheiten 100, welche dann die zugehörige Niedervolt-Gruppe bilden. Die Anordnung der Konvertereinheiten 20 sowie der zweiten Stromversorgungskreise II ist vorzugsweise derart, dass die Leuchten-Einheiten 100 im Wesentlichen über die gesamte Länge des Lichtbandsystems 1 hinweg angeordnet werden können. Das heißt, die Gesamtheit der zweiten Stromversorgungskreise II deckt vorzugsweise im Wesentlichen die gesamte Länge des Lichtbandsystems 1 ab, wobei - wie oben erwähnt - die zweiten Stromversorgungskreise II lediglich in bestimmten Abschnitten vorgesehen sein können. Wie in

Der Anschluss einer Konvertereinheit 20 an die Leitungen des ersten Stromversorgungskreises I erfolgt nunmehr dadurch, dass die Konvertereinheit 20 in die Tragschiene 2 eingesetzt und mechanisch fixiert wird, wobei gleichzeitig auch Kontakte ausgeschwenkt werden, über welche die in den Stromleitprofilen 13, 14 befindlichen Leitungen kontaktiert werden. Eine entsprechende Konvertereinheit ist in
Darüber hinaus weist die Konvertereinheit 20 ferner auch einen Stecker 27 auf, der über eine flexible Leitung 28 mit dem Gehäuse 21 verbunden ist. Über diesen Stecker 27 erfolgt dann die Verbindung der Konvertereinheit 20 mit den Leitungen 15, 16 des zweiten Stromversorgungskreises II. Die flexible Verbindungsleitung 27 erleichtert hierbei das Anschließen des Steckers 27, über den letztendlich die Niedervoltspannung zur Verfügung gestellt wird, an die Leitungen des zweiten Stromversorgungskreises II. Soll dabei die Konvertereinheit 20 zwei benachbarte Niedervolt-Gruppen, versorgen, so kann der Stecker 27 auch als entsprechende Brücke ausgebildet sein.In addition, the

Auch bei dieser zweiten Variante ist prinzipiell vorgesehen, dass die Konvertereinheiten 20 in regelmäßigen Abständen an dem Lichtbandsystem 1 angeordnet werden und den jeweils umgebenden Bereich mit der Niedervoltspannung versorgen.

Durch die erfindungsgemäße Lösung wird also die Möglichkeit geschaffen, flexibel Leuchten-Einheiten, welche eine Niedervoltspannung benötigen, an ein Lichtbandsystem anzuschließen. Die Lösung zeichnet sich dabei insbesondere auch dadurch aus, dass bereits bestehende Lichtbandsysteme ohne größeren Aufwand erweitert werden können, um das Anschließen derartiger Leuchten-Einheiten, welche beispielsweise LED-Lichtquellen beinhalten, zu ermöglichen, ohne dass jede Leuchten-Einheit einen eigenen Konverter enthalten muss.The solution according to the invention thus creates the possibility of flexibly connecting lighting units which require a low-voltage voltage to a lighting strip system. The solution is characterized in particular by the fact that existing lighting systems can be expanded without much effort to allow the connection of such lighting units, which include, for example, LED light sources, without each luminaire unit must contain its own converter ,
