Definitions

  • the invention relates to a lighting element for marking escape routes in vehicles, in particular in commercial aircraft, and its use as an escape route marking and an arrangement comprising at least one corresponding lighting element.
  • Known electrical systems include light units with one or more light sources arranged in a housing to protect against external influences, such as light bulbs or LEDs, which can be connected to the aircraft's on-board network by electrical wiring and operated via it. Backup batteries must also be provided to ensure the operation of the lighting units even if the vehicle electrical system fails. Corresponding systems regularly have a considerable mass and the cabling in particular has proven to be susceptible to faults.
  • Photoluminescent systems are also known from the prior art, in which the escape route marking has photoluminescent surfaces that are charged during normal operation by the ambient or cabin light and in the dark—for example, in the car. in the event of an emergency - also glow over a longer period of time and thus show the escape routes.
  • the photoluminescent escape route marking which is regularly available in the form of strips, can usually be attached with little effort in the aircraft cabin of an aircraft, so that a reconfiguration of the escape route marking, for example when changing the cabin design, is possible with manageable effort. For the installation, it is only necessary to ensure that the photoluminescent surfaces can be sufficiently charged by the cabin lighting during normal operation.
  • the object of the present invention is to create a lighting element for marking escape routes in vehicles, in particular in commercial aircraft, in which the disadvantages and problems from the prior art no longer occur or only to a reduced extent.
  • the invention relates to a lighting element for marking escape routes in vehicles, comprising a flat substrate with a base area provided for attachment on the first side and at least one flat electrical lighting element on the second side, the ratio of the surface area of the base area to the thickness of the lighting element being greater is than 500 mm and the ratio of the surface area of the base to the mass of the lighting element is greater than 100 mm 2 / ⁇ .
  • the invention also relates to the use of a lighting element according to the invention as an escape route marking on board a commercial aircraft, the lighting element being attached to the base of the substrate on a structure on board the commercial aircraft and connected to the on-board electrical system of the commercial aircraft.
  • the invention also relates to an arrangement for marking escape routes in a vehicle, comprising at least one lighting element according to the invention, a power supply infrastructure extending over the passenger area of a vehicle for the at least one lighting element, so that it can be arranged in a large number of different positions in the passenger area and can be supplied with energy via the Energy supply infrastructure can be supplied, and a signal transmitter for generating and sending out control signals for the at least one lighting element.
  • An element is considered “flat” if the characteristic dimensions of a surface of the element are at least one order of magnitude (power of ten) larger than the characteristic dimension of the element perpendicular to this surface.
  • the characteristic dimensions are e.g Length and width , in the case of a circular area the diameter .
  • the dimension perpendicular to the area in question is also commonly referred to as the "thickness" of the element .
  • the invention has recognized that lighting elements for escape route markings in vehicles, in particular in commercial aircraft, can be created by resorting to fundamentally known technologies, which are electrically operated and therefore independent of the incidence of light, but can nevertheless be easily and flexibly integrated into the vehicle or . have its cabin integrated. Independent of the final lighting elements or other resulting technical specifications, the invention has for the first time created a flexibly usable, electrically operated lighting element, which has practically no design requirements for the structure accommodating the lighting element, solely through the dimensioning specified according to the invention. As a result, for example, the change in the escape route marking that usually accompanies a change in the cabin design in a commercial aircraft is also possible without any problems, although the lighting elements according to the invention are also operated electrically.
  • this is achieved by specifying the two ratios 500 771771 and achieved .
  • the interaction of the surface area of the base area of the substrate of the lighting element according to the invention with the thickness and the mass of the lighting element ensures that the lighting element is independent of the technology ultimately used for the lighting element and the connection to the supporting structure, for the various variants listed below are, even at extreme accelerations, such as those for commercial aircraft for certain emergency situations are set at up to 9g (nine times the acceleration due to gravity) (cf . e.g . 14 CER ⁇ 25 . 561 ) , fundamentally do not represent such a load for the supporting structure that it would have to be specially designed for it . Rather, the planar, flat design ensures that even with very high accelerations, only extremely small forces and moments are introduced into the receiving structure, which as a rule do not require any special consideration and in particular no structural adjustment of the supporting structure.
  • the ratio of the surface area of the base to the thickness of the lighting element is greater than 900 777777, preferably greater than 2000 777777, and/or the ratio of the surface area of the base to the mass of the lighting element is greater than 150 mm 2 /g, preferably greater than 250 mm 2 /g.
  • the maximum load on the supporting structure can be further reduced by appropriate boundary conditions, which can be achieved by suitably selecting available technologies.
  • the substrate can be rigid, in which case it is preferably shaped in such a way that a flat, simply curved or a free-form base surface results.
  • the shape of the substrate can in particular be adapted to the shape of the surface of the support structure to which the lighting element is to be attached.
  • the substrate is flexible so that it can be adapted to the shape of a supporting structure in situ.
  • the substrate can be a flexible plastic film.
  • the base provided for attachment can be self-adhesive at least in regions, preferably over the entire surface. Due to the self-adhesive design, a simple attachment of the lighting element according to the invention is possible. From the specifications according to the invention for the conditions described above, it follows that the base area is regularly large enough - at least insofar as it is self-adhesive over the entire surface - to carry all expected loads solely via the adhesive surface into the To be able to initiate supporting structure without the lighting element detaching itself from the supporting structure. In this way, a planar, often even load introduction into the supporting structure is achieved.
  • the lighting element has at least one breakthrough area for fasteners, such as. Nails, rivets or screws.
  • the breakthrough area can be used as an opening for Implementation of a corresponding fastener can be formed.
  • the at least one breakthrough area is basically closed and only opened before or during the passage of a fastening element.
  • the lighting element - if necessary. in addition to gluing - to be attached to a supporting structure.
  • the at least one light-emitting element can be an OLED, plasma or electroluminescence element. If several light-emitting elements are provided for one lighting element, these can be connected in series or in parallel, at least in groups. However, it is also possible for the lighting elements to be at least partially individually controllable.
  • the lines required for connecting the at least one light-emitting element are preferably arranged on the second side of the substrate. Furthermore, the corresponding lines are preferably routed to the edge of the second side of the substrate. There interfaces for connecting the lighting element to a wired power supply, for example. the electrical system of a commercial aircraft, be provided.
  • a chargeable energy storage device preferably comprising a charging circuit, a control circuit for controlling the at least one light-emitting element, an antenna for receiving control signals and/or an antenna for wireless energy transmission.
  • a rechargeable battery or a (super) capacitor - can the lighting element can also be operated without an external power supply in an emergency.
  • the provision of additional elements, such as Emergency supply batteries with a separate charging circuit, as in systems based on the prior art, can thus be omitted.
  • the control circuit can switch the at least one light-emitting element on or off depending on received control signals, which can be received via a suitable antenna or a wired data line, and/or when the external power supply fails.
  • the control circuit can also be designed to send status messages to a higher-level controller. This information can be sent via the antenna and/or the data line that is provided for receiving control signals.
  • the at least one light-emitting element, the energy store, the charging circuit, the control circuit, the antenna(s) and/or the required lines are printed onto the substrate, preferably onto the second side of the substrate. Due to the low complexity of the individual, if necessary. on zubuchenden elements and given the prescribed proportions of the lighting element or of the substrate regularly sufficient printing area, the elements in question can be printed using standard industrial processes, such as e.g. Rotogravure, offset printing, flexographic printing, inkjet printing or screen printing are applied in layers. If all elements to be printed are arranged on the second side of the substrate, this simplifies production. In particular, no passages ("vias") through the substrate are required.
  • Printed components offer the additional advantage over surface mount components that they Do not limit the flexibility of the substrate or limit it only to a lesser extent.
  • the printed light-emitting element can in particular be printed light-emitting diodes, which are regularly homogeneously flexible.
  • a continuous protective coating that is at least translucent at least in the areas of the light-emitting elements is arranged on the second side of the substrate.
  • the protective coating can protect the at least one light-emitting element, the energy store, the charging circuit, the control circuit, the antenna(s) and/or the lines on the second side of the substrate from external influences, in particular from moisture. Since the protective coating is at least translucent at least in the areas in which the light-emitting elements are arranged, the light generated by the light-emitting elements can pass through the protective coating. However, the protective coating, at least in the areas in question, can also be transparent.
  • the protective coating can be a layer of paint or a coating made of plastic.

Description

Fluchtwegmarkierung in Fahrzeugen Escape route markings in vehicles
Die Erfindung betri f ft ein Beleuchtungselement für die Fluchtwegmarkierung in Fahrzeugen, insbesondere in Verkehrs flugzeugen, sowie dessen Verwendung als Fluchtwegmarkierung und eine Anordnung umfassend wenigstens ein entsprechendes Beleuchtungselement . The invention relates to a lighting element for marking escape routes in vehicles, in particular in commercial aircraft, and its use as an escape route marking and an arrangement comprising at least one corresponding lighting element.
In Verkehrs flugzeugen sind im Stand der Technik grundsätzlich zwei Varianten für zwingend vorgeschriebene Fluchtwegmarkierungen bekannt , um Passagieren im Notfall bei Dunkelheit und Aus fall der allgemeinen Kabinenbeleuchtung den Weg zu den Notausgängen zu weisen . In commercial aircraft, there are basically two variants known in the prior art for mandatory escape route markings in order to show passengers the way to the emergency exits in an emergency when it is dark and the general cabin lighting fails.
Bekannte elektrische Systeme umfassen Leuchteinheiten mit einem oder mehreren in einem Gehäuse zum Schutz vor äußeren Einflüssen angeordneten Leuchtmitteln, wie Glühbirnen oder LEDs , die durch elektrische Verkabelung an das Bordnetz des Flugzeuges angebunden und darüber betrieben werden können . Zusätzlich müssen noch Puf ferbatterien vorgesehen werden, die den Betrieb der Leuchteinheiten auch bei Aus fall des Bordnetzes sicherstellen können . Entsprechende Systeme weisen regelmäßig eine erhebliche Masse auf und insbesondere die Verkabelung hat sich als störungsanfällig erwiesen . Known electrical systems include light units with one or more light sources arranged in a housing to protect against external influences, such as light bulbs or LEDs, which can be connected to the aircraft's on-board network by electrical wiring and operated via it. Backup batteries must also be provided to ensure the operation of the lighting units even if the vehicle electrical system fails. Corresponding systems regularly have a considerable mass and the cabling in particular has proven to be susceptible to faults.
Aufgrund der erforderlichen Verkabelung, aber auch weil für die Gehäuse der Leuchteinheiten regelmäßig geeignete Aufnahmen in der aufnehmenden Struktur, bspw . dem Boden, vorgesehen sein müssen, sind bekannte elektrische Systeme nicht oder nur kaum rekonfigurierbar . Soll die Kabinengestaltung eines Flugzeuges geändert werden, sind daher entweder die Möglichkeiten der Änderungen darauf beschränkt , keine Änderungen an der Fluchtweg- markierung zu erfordern, oder es ist eine aufwendige und äußerst kostenintensive Neuinstallation einer Fluchtwegmarkierung erforderlich . Due to the required wiring, but also because for the housing of the lighting units regularly suitable shots in the receiving structure, for example. the ground, must be provided, known electrical systems are not or only hardly reconfigurable. If the cabin design of an aircraft is to be changed, either the possibilities for changes are limited to this, no changes to the escape route to require marking, or an elaborate and extremely costly reinstallation of an escape route marking is required.
Aus dem Stand der Technik sind ebenfalls photolumines zente Systeme bekannt , bei denen die Fluchtwegmarkierung photolumines zente Oberflächen aufweist , die im Normalbetrieb durch das Umgebungs- oder Kabinenlicht aufgeladen werden und bei Dunkelheit - bspw . im Falle eines Notfalls - auch über einen längeren Zeitraum nachleuchten und so die Fluchtwege anzeigen . Die regelmäßig in Form von Strei fen verfügbare photolumines zente Fluchtwegmarkierung lässt sich in der Regel mit geringem Aufwand in der Flugzeugkabine eines Flugzeugs befestigen, sodass auch eine Rekonfiguration der Fluchtwegmarkierung, bspw . bei Veränderung der Kabinengestaltung, mit überschaubarem Aufwand möglich ist . Für die Installation ist lediglich sicherzustellen, dass die photolumines zente Oberflächen im Normalbetrieb ausreichend von der Kabinenbeleuchtung aufgeladen werden können . Photoluminescent systems are also known from the prior art, in which the escape route marking has photoluminescent surfaces that are charged during normal operation by the ambient or cabin light and in the dark—for example, in the car. in the event of an emergency - also glow over a longer period of time and thus show the escape routes. The photoluminescent escape route marking, which is regularly available in the form of strips, can usually be attached with little effort in the aircraft cabin of an aircraft, so that a reconfiguration of the escape route marking, for example when changing the cabin design, is possible with manageable effort. For the installation, it is only necessary to ensure that the photoluminescent surfaces can be sufficiently charged by the cabin lighting during normal operation.
Letzteres ist aufgrund der vermehrt für die Kabinenbeleuchtung eingesetzten LED-Technologie j edoch nicht mehr immer möglich . Auch wenn LED-Beleuchtungen den Betreibern eine große Variabilität für die Beleuchtung einer Flugzeugkabine bei geringem Energieverbrauch bieten, ist nicht sichergestellt , dass zumindest in den aus Sicherheitsgesichtspunkten relevanten Flugphasen ausreichend Licht in dem für die Aufladung der photolumi- nes zenten Fluchtwegmarkierung relevanten spektralen Bereich zur Verfügung gestellt wird . However, the latter is no longer always possible due to the LED technology increasingly used for cabin lighting. Even if LED lighting offers operators great variability for lighting an aircraft cabin with low energy consumption, there is no guarantee that sufficient light will be available in the spectral range relevant for charging the photoluminescent central escape route marking, at least in the flight phases that are relevant from a safety point of view is provided .
Aufgabe der vorliegenden Erfindung ist es , ein Beleuchtungselement für die Fluchtwegmarkierung in Fahrzeugen, insbesondere in Verkehrs flugzeugen, zu schaf fen, bei dem die Nachteile und Probleme aus dem Stand der Technik nicht mehr oder nur noch in vermindertem Umfang auf treten . The object of the present invention is to create a lighting element for marking escape routes in vehicles, in particular in commercial aircraft, in which the disadvantages and problems from the prior art no longer occur or only to a reduced extent.
Die Aufgabe wird gelöst durch ein Beleuchtungselement gemäß dem Hauptanspruch, sowie dessen Verwendung und durch eine Anordnung gemäß den weiteren unabhängigen Ansprüchen . Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche . The object is achieved by a lighting element according to the main claim and its use and by an arrangement according to the other independent claims. Advantageous developments are the subject matter of the dependent claims.
Demnach betri f ft die Erfindung ein Beleuchtungselement für die Fluchtwegmarkierung in Fahrzeugen umfassend ein flächiges Substrat mit einer zur Befestigung vorgesehenen Grundfläche auf der ersten Seite und wenigstens ein flächiges elektrisches Leuchtelement auf der zweiten Seite , wobei das Verhältnis des Flächeninhalts der Grundfläche zur Dicke des Beleuchtungselementes größer ist als 500 mm und das Verhältnis des Flächeninhalts der Grundfläche zur Masse des Beleuchtungselementes größer ist als lOO mm2/^ . Accordingly, the invention relates to a lighting element for marking escape routes in vehicles, comprising a flat substrate with a base area provided for attachment on the first side and at least one flat electrical lighting element on the second side, the ratio of the surface area of the base area to the thickness of the lighting element being greater is than 500 mm and the ratio of the surface area of the base to the mass of the lighting element is greater than 100 mm 2 /^.
Weiterhin betri f ft die Erfindung die Verwendung eines erfindungsgemäßen Beleuchtungselementes als Fluchtwegemarkierung an Bord eines Verkehrs flugzeugs , wobei das Beleuchtungselement mit der Grundfläche des Substrats an einer Struktur an Bord des Verkehrs flugzeuges befestigt und mit dem elektrischen Bordnetz des Verkehrs flugzeuges verbunden ist . The invention also relates to the use of a lighting element according to the invention as an escape route marking on board a commercial aircraft, the lighting element being attached to the base of the substrate on a structure on board the commercial aircraft and connected to the on-board electrical system of the commercial aircraft.
Die Erfindung betri f ft auch eine Anordnung zur Fluchtwegmarkierung in einem Fahrzeug umfassend wenigstens ein erfindungsgemäßes Beleuchtungselement , eine sich über den Passagierbereich eines Fahrzeugs erstreckende Energieversorgungsinfrastruktur für das wenigstens eine Beleuchtungselement , sodass dieses an einer Viel zahl verschiedener Positionen im Passagierbereich anordnenbar und mit Energie über die Energieversorgungsinfrastruktur versorgbar ist , und einem Signalgeber zur Erzeugung und Aussendung von Steuerungssignalen für das wenigstens eine Beleuchtungselement . The invention also relates to an arrangement for marking escape routes in a vehicle, comprising at least one lighting element according to the invention, a power supply infrastructure extending over the passenger area of a vehicle for the at least one lighting element, so that it can be arranged in a large number of different positions in the passenger area and can be supplied with energy via the Energy supply infrastructure can be supplied, and a signal transmitter for generating and sending out control signals for the at least one lighting element.
Zunächst werden einige in Zusammenhang mit der Erfindung verwendete Begri f fe erläutert . First, some terms used in connection with the invention are explained.
Ein Element gilt als „flächig" , wenn die charakteristischen Abmaße einer Fläche des Elementes um j eweils wenigstens eine Größenordnung ( Zehnerpotenz ) größer sind, als das charakteristische Abmaß des Elements senkrecht zu dieser Fläche . Bei einer rechteckigen Fläche sind die charakteristischen Abmaße bspw . die Länge und Breite , bei einer kreis förmigen Fläche der Durchmesser . Das Abmaß senkrecht zur fraglichen Fläche wird gemeinhin auch als „Dicke" des Elements bezeichnet . An element is considered "flat" if the characteristic dimensions of a surface of the element are at least one order of magnitude (power of ten) larger than the characteristic dimension of the element perpendicular to this surface. In the case of a rectangular surface, the characteristic dimensions are e.g Length and width , in the case of a circular area the diameter .The dimension perpendicular to the area in question is also commonly referred to as the "thickness" of the element .
Die Erfindung hat erkannt , dass sich unter Rückgri f f auf grundsätzlich bekannte Technologien Beleuchtungselemente für die Fluchtwegmarkierung in Fahrzeugen, insbesondere in Verkehrs flugzeuge , schaf fen lassen, die elektrisch betrieben und somit unabhängig vom Lichteinfall darauf sind, sich aber dennoch einfach und flexibel in das Fahrzeug bzw . dessen Kabine integrieren lassen . Die Erfindung hat dabei unabhängig von letztendlichen Leuchtelementen oder sonstigen sich daraus ergebenden technischen Vorgaben allein durch die erfindungsgemäß vorgegebene Dimensionierung erstmals ein flexibl einsetzbares , elektrische betriebenes Beleuchtungselement geschaf fen, welches praktisch keine konstruktiven Anforderungen an die das Beleuchtungselement aufnehmende Struktur aufweist . In der Folge ist beispielsweise auch die mit einer Veränderung der Kabinengestaltung bei einem Verkehrs flugzeug in der Regel einhergehende Veränderung der Fluchtwegmarkierung problemlos möglich, obwohl auch die erfindungsgemäßen Beleuchtungselemente elektrisch betrieben sind . Dies wird erfindungsgemäß durch die Vorgabe der beiden Verhältnisse 500 771771 und erreicht . Durch das Zusammenspiel von Flächeninhalt der Grundfläche des Substrats des erfindungsgemäßen Beleuchtungselementes mit der Dicke und der Masse des Beleuchtungselementes wird sichergestellt , dass das Beleuchtungselement unabhängig von der letztendlich verwendeten Technologie für das Leuchtelement sowie die Anbindung an die tragende Struktur, für die nachfolgend noch diverse Varianten ausgeführt sind, selbst bei extremen Beschleunigungen, wie sie bspw . für Verkehrs flugzeuge für bestimmte Notsituationen auf bis zu 9g ( das neun- fache der Erdbeschleunigung) festgelegt sind (vgl . bspw . 14 CER § 25 . 561 ) , grundsätzlich keine solche Belastung für die aufnehmende Tragstruktur darstellen, dass diese dafür besonders ausgebildet sein müsste . Vielmehr ist durch die flächige , flache Ausgestaltung sichergestellt , dass selbst bei sehr hohen Beschleunigungen nur äußerst geringe Kräfte und Momente in die aufnehmende Struktur eingebracht werden, die in der Regel keiner besonderen Betrachtung und insbesondere keiner strukturellen Anpassung der Tragstruktur bedürfen . The invention has recognized that lighting elements for escape route markings in vehicles, in particular in commercial aircraft, can be created by resorting to fundamentally known technologies, which are electrically operated and therefore independent of the incidence of light, but can nevertheless be easily and flexibly integrated into the vehicle or . have its cabin integrated. Independent of the final lighting elements or other resulting technical specifications, the invention has for the first time created a flexibly usable, electrically operated lighting element, which has practically no design requirements for the structure accommodating the lighting element, solely through the dimensioning specified according to the invention. As a result, for example, the change in the escape route marking that usually accompanies a change in the cabin design in a commercial aircraft is also possible without any problems, although the lighting elements according to the invention are also operated electrically. According to the invention, this is achieved by specifying the two ratios 500 771771 and achieved . The interaction of the surface area of the base area of the substrate of the lighting element according to the invention with the thickness and the mass of the lighting element ensures that the lighting element is independent of the technology ultimately used for the lighting element and the connection to the supporting structure, for the various variants listed below are, even at extreme accelerations, such as those for commercial aircraft for certain emergency situations are set at up to 9g (nine times the acceleration due to gravity) (cf . e.g . 14 CER § 25 . 561 ) , fundamentally do not represent such a load for the supporting structure that it would have to be specially designed for it . Rather, the planar, flat design ensures that even with very high accelerations, only extremely small forces and moments are introduced into the receiving structure, which as a rule do not require any special consideration and in particular no structural adjustment of the supporting structure.
Es ist bevorzugt , wenn das Verhältnis des Flächeninhalts der Grundfläche zur Dicke des Beleuchtungselementes größer als 900 777777, vorzugsweise größer als 2000 777777 ist , und/oder das Verhältnis des Flächeninhalts der Grundfläche zur Masse des Beleuchtungselementes größer als 150 mm2/g, vorzugsweise größer als 250 mm2/g ist . Durch entsprechende Randbedingungen, die durch geeignete Auswahl verfügbarer Technologien erreichbar sind, kann die maximale Belastung der Tragstruktur weiter reduziert werden . It is preferred if the ratio of the surface area of the base to the thickness of the lighting element is greater than 900 777777, preferably greater than 2000 777777, and/or the ratio of the surface area of the base to the mass of the lighting element is greater than 150 mm 2 /g, preferably greater than 250 mm 2 /g. The maximum load on the supporting structure can be further reduced by appropriate boundary conditions, which can be achieved by suitably selecting available technologies.
Das Substrat kann starr sein, wobei es dann vorzugsweise so geformt ist , dass sich eine ebene , einfach-gekrümmte oder eine Frei form-Grundfläche ergibt . Die Form des Substrats kann dabei insbesondere an die Form der Oberfläche der Tragstruktur, an der das Beleuchtungselement befestigt werden soll , angepasst sein . Es ist aber bevorzugt , wenn das Substrat flexibel ist , um sich so in situ an die Form einer Tragstruktur anpassen zu können . Beispielsweise kann es sich bei dem Substrat um eine flexible Kunststof f folie handeln . The substrate can be rigid, in which case it is preferably shaped in such a way that a flat, simply curved or a free-form base surface results. The shape of the substrate can in particular be adapted to the shape of the surface of the support structure to which the lighting element is to be attached. However, it is preferred if the substrate is flexible so that it can be adapted to the shape of a supporting structure in situ. For example, the substrate can be a flexible plastic film.
Die zur Befestigung vorgesehene Grundfläche kann wenigstens bereichsweise , vorzugsweise voll flächig selbstklebend sein . Durch die selbstklebende Ausgestaltung ist eine einfache Anbringung des erfindungsgemäßen Beleuchtungselementes möglich . Dabei ergibt sich aus den erfindungsgemäßen Vorgaben für die oben beschriebenen Verhältnisse , dass die Grundfläche regelmäßig groß genug ist , um - zumindest sofern sie voll flächig selbstklebend ist - bereits bei typischen Eigenschaften von bekannten Klebebeschichtungen für Montagezwecke sämtliche zu erwartenden Belastungen allein über die Klebefläche in die Tragstruktur einleiten zu können, ohne dass sich das Beleuchtungselement von der Tragstruktur löst . Dabei wird weiterhin eine flächige , häufig gleichmäßige Belastungseinleitung in die Tragstruktur erreicht . The base provided for attachment can be self-adhesive at least in regions, preferably over the entire surface. Due to the self-adhesive design, a simple attachment of the lighting element according to the invention is possible. From the specifications according to the invention for the conditions described above, it follows that the base area is regularly large enough - at least insofar as it is self-adhesive over the entire surface - to carry all expected loads solely via the adhesive surface into the To be able to initiate supporting structure without the lighting element detaching itself from the supporting structure. In this way, a planar, often even load introduction into the supporting structure is achieved.
Alternativ oder zusätzlich ist es möglich, dass das Beleuchtungselement wenigstens einen Durchbruchsbereich für Befestigungselemente , wie bspw . Nägel , Nieten oder Schrauben, aufweist . Der Durchbruchsbereich kann dabei als Öf fnung zur Durchführung eines entsprechenden Befestigungselementes ausgebildet sein . Es ist aber bevorzugt , wenn der wenigstens eine Durchbruchsbereich grundsätzlich geschlossen und erst vor oder bei der Durchführung eines Befestigungselementes geöf fnet wird . An dem oder den Durchbruchsbereichen kann das Beleuchtungselement - ggf . ergänzend zu einer Verklebung - an eine Tragstruktur befestigt werden . Alternatively or additionally, it is possible that the lighting element has at least one breakthrough area for fasteners, such as. Nails, rivets or screws. The breakthrough area can be used as an opening for Implementation of a corresponding fastener can be formed. However, it is preferred if the at least one breakthrough area is basically closed and only opened before or during the passage of a fastening element. At the or the breakthrough areas, the lighting element - if necessary. in addition to gluing - to be attached to a supporting structure.
Das wenigstens eine Leuchtelement kann ein OLED- , Plasma- oder Elektrolumines zenz-Element sein . Sind mehrere Leuchtelemente bei einem Beleuchtungselement vorgesehen, können diese wenigstens gruppenweise seriell oder parallel verschaltet sein . Es ist aber auch möglich, die Leuchtelemente wenigstens teilweise einzeln ansteuerbar aus zugestalten . The at least one light-emitting element can be an OLED, plasma or electroluminescence element. If several light-emitting elements are provided for one lighting element, these can be connected in series or in parallel, at least in groups. However, it is also possible for the lighting elements to be at least partially individually controllable.
Die für den Anschluss des wenigstens einen Leuchtelementes erforderlichen Leitungen sind vorzugsweise auf der zweiten Seite des Substrats angeordnet . Weiterhin sind die entsprechenden Leitungen vorzugsweise bis zum Rand der zweiten Seite des Substrats geführt . Dort können Schnittstellen zum Anschluss des Beleuchtungselementes an eine drahtgebundene Energieversorgung, bspw . das Bordnetz eines Verkehrs flugzeuges , vorgesehen sein . The lines required for connecting the at least one light-emitting element are preferably arranged on the second side of the substrate. Furthermore, the corresponding lines are preferably routed to the edge of the second side of the substrate. There interfaces for connecting the lighting element to a wired power supply, for example. the electrical system of a commercial aircraft, be provided.
Auf dem Substrat , vorzugsweise auf der zweiten Seite des Substrats , können weiterhin ein aufladbarer Energiespeicher, vorzugsweise umfassend eine Ladeschaltung, eine Steuerungsschaltung zum Steuern des wenigstens einen Leuchtelementes , eine Antenne zum Empfang von Steuerungssignalen und/oder eine Antenne zur drahtlosen Energieübertragung vorgesehen sein . On the substrate, preferably on the second side of the substrate, there can also be a chargeable energy storage device, preferably comprising a charging circuit, a control circuit for controlling the at least one light-emitting element, an antenna for receiving control signals and/or an antenna for wireless energy transmission.
Durch den aufladbaren Energiespeicher - bspw . eine aufladbare Batterie oder ein ( Super- ) Kondensator - kann das Beleuchtungs- element im Notfall auch ohne externe Energieversorgung betrieben werden . Das Vorsehen einer Ladeschaltung und/oder Steuerungsschaltung, insbesondere wenn letztere Steuerungssignale über ein ebenfalls auf der zweiten Seite angeordnete Antenne empfängt , vereinfacht die Installation des erfindungsgemäßen Beleuchtungselementes , da dieses dann lediglich an eine externe Energieversorgung angeschlossen werden muss . Das Vorsehen zusätzlicher Elemente , wie bspw . Notversorgungsbatterien mit gesonderter Ladeschaltung, wie bei Systemen auf dem Stand der Technik, kann so entfallen . Due to the rechargeable energy storage - for example. a rechargeable battery or a (super) capacitor - can the lighting element can also be operated without an external power supply in an emergency. The provision of a charging circuit and/or control circuit, in particular if the latter receives control signals via an antenna also arranged on the second side, simplifies the installation of the lighting element according to the invention, since this then only has to be connected to an external power supply. The provision of additional elements, such as Emergency supply batteries with a separate charging circuit, as in systems based on the prior art, can thus be omitted.
Selbst auf eine drahtgebundene Energieversorgung kann verzichtet werden, wenn das Beleuchtungselement eine Antenne zur drahtlosen Energieübertragung aufweist . I st das Beleuchtungselement für eine Installation in einem Bereich mit geeignetem magnetischem Fluss vorgesehen, kann auf eine Energiezuführung per Kabel vollständig verzichtet werden . Even a wired power supply can be dispensed with if the lighting element has an antenna for wireless power transmission. If the lighting element is intended for installation in an area with a suitable magnetic flux, there is no need for a power supply by cable.
Die Steuerungsschaltung kann das wenigstens eine Leuchtelement in Abhängigkeit von empfangenen Steuerungssignalen, die über eine geeignete Antenne oder eine kabelgebundene Datenleitung empfangen werden können, und/oder bei Wegfall der externen Energieversorgung an- oder ausschalten . Die Steuerungsschaltung kann auch dazu ausgebildet sein, Statusmitteilung an eine übergeordnete Steuerung aus zusenden . Diese Informationen können über die Antenne und/oder die Datenleitung, die zum Empfang von Steuerungssignalen vorgesehen ist , gesendet werden . The control circuit can switch the at least one light-emitting element on or off depending on received control signals, which can be received via a suitable antenna or a wired data line, and/or when the external power supply fails. The control circuit can also be designed to send status messages to a higher-level controller. This information can be sent via the antenna and/or the data line that is provided for receiving control signals.
Es ist bevorzugt , wenn das wenigstens eine Leuchtelement , der Energiespeicher, die Ladeschaltung, die Steuerungsschaltung, die Antennen (n) und/oder die erforderlichen Leitungen auf das Substrat , vorzugsweise auf die zweite Seite des Substrats , aufgedruckt sind . Aufgrund der geringen Komplexität der einzelnen, ggf . auf zudruckenden Elemente sowie der angesichts der vorgeschriebenen Größenverhältnisse des Beleuchtungselementes bzw . des Substrats regelmäßig ausreichenden Druckfläche können die fraglichen Elemente mit industrieüblichen Verfahren, wie bspw . Tiefdruck, Of fsetdruck, Flexodruck, Tintenstrahldruck o- der Siebdruck, schichtweise aufgebracht werden . Sind sämtliche zu druckenden Elemente auf der zweiten Seite des Substrats angeordnet , vereinfacht das die Herstellung . Insbesondere sind keine Durchgänge ( „Vias" ) durch das Substrat erforderlich . It is preferred if the at least one light-emitting element, the energy store, the charging circuit, the control circuit, the antenna(s) and/or the required lines are printed onto the substrate, preferably onto the second side of the substrate. Due to the low complexity of the individual, if necessary. on zudruckenden elements and given the prescribed proportions of the lighting element or of the substrate regularly sufficient printing area, the elements in question can be printed using standard industrial processes, such as e.g. Rotogravure, offset printing, flexographic printing, inkjet printing or screen printing are applied in layers. If all elements to be printed are arranged on the second side of the substrate, this simplifies production. In particular, no passages ("vias") through the substrate are required.
Gedruckte Komponenten bieten gegenüber oberflächenmontierten Komponenten den zusätzlichen Vorteil , dass sie eine evtl . Biegsamkeit des Substrats nicht oder nur weniger stark einschränken . Bei dem gedruckten Leuchtelement kann es sich insbesondere um gedruckte Leuchtdioden handeln, die regelmäßig homogen flexibel sind . Printed components offer the additional advantage over surface mount components that they Do not limit the flexibility of the substrate or limit it only to a lesser extent. The printed light-emitting element can in particular be printed light-emitting diodes, which are regularly homogeneously flexible.
Es ist bevorzugt , wenn auf der zweiten Seite des Substrats eine durchgehende , wenigstens in den Bereichen der Leuchtelemente wenigstens transluzente Schutzbeschichtung angeordnet ist . Durch die Schutzbeschichtung kann das wenigstens eine Leuchtelement , der Energiespeicher, die Ladeschaltung, die Steuerungsschaltung, die Antenne (n) und/oder die Leitungen auf der zweiten Seite des Substrats vor äußeren Einflüssen, insbesondere vor Feuchtigkeit , geschützt werden . In dem die Schutzbeschichtung wenigstens in den Bereichen wenigstens transluzent ist , in denen die Leuchtelemente angeordnet sind, kann das von den Leuchtelementen erzeugte Licht durch die Schutzbeschichtung hindurchtreten . Die Schutzbeschichtung wenigstens in den fraglichen Bereichen kann aber auch transparent sein . Bei der Schutzbeschichtung kann es sich um eine Lackschicht oder um eine Beschichtung aus Kunststof f handeln . Insbesondere wenn eine Viel zahl von Beleuchtungselementen für eine identische Verwendung benötigt werden - bspw . zur Bestückung der Sitzstruktur einzelner Sitze oder zu Sitzreihen fest verbundener Sitze - kann vorgesehen sein, eine Anschlussleitung einstückig mit dem Beleuchtungselement aus zuführen . Dazu kann insbesondere das Substrat des Beleuchtungselementes für den gewünschten Verlauf der Anschlussleitung entsprechend erweitert sein, wobei auf dieser Erweiterung dann analog zu den Leiterbahnen des Beleuchtungselementes elektrische Zuleitungen ausgebildet sein können und/oder die Erweiterung mit einer Schutzbeschichtung versehen sein kann, die vorzugsweise einstückig mit der Schutzbeschichtung des Beleuchtungselementes ausgebildet ist . Insbesondere , wenn das Beleuchtungselement in einem Druckverfahren hergestellt wird, lässt sich dabei problemlos auch eine entsprechende Anschlussleitung einstückig damit ausbilden . It is preferred if a continuous protective coating that is at least translucent at least in the areas of the light-emitting elements is arranged on the second side of the substrate. The protective coating can protect the at least one light-emitting element, the energy store, the charging circuit, the control circuit, the antenna(s) and/or the lines on the second side of the substrate from external influences, in particular from moisture. Since the protective coating is at least translucent at least in the areas in which the light-emitting elements are arranged, the light generated by the light-emitting elements can pass through the protective coating. However, the protective coating, at least in the areas in question, can also be transparent. The protective coating can be a layer of paint or a coating made of plastic. Especially when a variety of lighting elements are required for an identical use - for example. for equipping the seat structure of individual seats or seats that are firmly connected to rows of seats - it can be provided that a connection line is made in one piece with the lighting element. For this purpose, in particular, the substrate of the lighting element can be extended accordingly for the desired course of the connection line, in which case electrical supply lines can then be formed on this extension analogous to the conductor tracks of the lighting element and/or the extension can be provided with a protective coating, which is preferably integral with the Protective coating of the lighting element is formed. In particular, if the lighting element is produced in a printing process, a corresponding connection line can also be formed in one piece with it without any problems.

Die Energieversorgungsinfrastruktur der Anordnung ist so ausgebildet , dass ein oder mehrere Beleuchtungselemente wahlweise an verschiedensten Position im Passagierbereich eines Fahrzeuges , bspw . der Passagierkabine eines Verkehrs flugzeuges , angeordnet und dennoch einfach von über die Energieversorgungsinfrastruktur mit Energie versorgt werden können . Durch eine entsprechende Energieversorgungsinfrastruktur wird eine erhebliche Flexibilität bei der Neugestaltung von Fahrzeuginnenräumen ermöglicht , da die häufig zwingend vorgeschriebene Fluchtwegmarkierung durch erfindungsgemäße Beleuchtungselemente und die Energieversorgungsinfrastruktur an unterschiedlichsten, bei geeigneter Ausgestaltung der Energieversorgungsinfrastruktur nahezu beliebigen Positionen und an praktisch beliebigen Strukturen, wie Wand- oder Bodenpaneelen, aber auch an Sitzstrukturen oder sonstigen Möbelstrukturen, angeordnet werden können . Die Energieversorgungsinfrastruktur ist vorzugsweise an die Beleuchtungselemente angepasst . Sind die Beleuchtungselemente für eine drahtgebundene Energiezuführung ausgebildet , kann die Energieversorgungsinfrastruktur eine Viel zahl von Anschlussmöglichkeiten für geeignete Zuleitung umfassen . Soll die Energie drahtlos an die Beleuchtungselemente übertragen werden, umfasst die Energieversorgungsinfrastruktur vorzugsweise dafür geeignete Sendemodule . The energy supply infrastructure of the arrangement is designed in such a way that one or more lighting elements can be installed in a wide variety of positions in the passenger area of a vehicle, e.g. arranged in the passenger cabin of a commercial aircraft and yet can be easily supplied with energy from the energy supply infrastructure. A corresponding energy supply infrastructure allows considerable flexibility when redesigning vehicle interiors made possible because the often mandatory escape route marking by lighting elements according to the invention and the energy supply infrastructure can be arranged in a wide variety of positions, with a suitable design of the energy supply infrastructure in almost any position and on practically any structures, such as wall or floor panels, but also on seat structures or other furniture structures. The energy supply infrastructure is preferably adapted to the lighting elements. If the lighting elements are designed for a wired energy supply, the energy supply infrastructure can include a large number of connection options for suitable supply lines. If the energy is to be transmitted wirelessly to the lighting elements, the energy supply infrastructure preferably includes transmission modules suitable for this.
Vergleichbares gilt für den Signalgeber der Anordnung, der die Steuerungssignale in einer für die Beleuchtungselemente geeigneten Form ausgeben muss . I st eine kabelgebundene Signalübertragung, bspw . in Form von Impulsen oder der anliegenden Spannung, vorgesehen, ist der Signalgeber so ausgebildet , dass er die entsprechenden Impulse in die Energieversorgung einspeisen oder die Spannung der Energieversorgung entsprechend regeln kann . Alternativ oder zusätzlich kann der Signalgeber zum Aussenden von Steuerungssignalen per Funk ausgebildet sein . The same applies to the signal generator of the arrangement, which must output the control signals in a form suitable for the lighting elements. I s a wired signal transmission, e.g. in the form of pulses or the applied voltage, the signal transmitter is designed in such a way that it can feed the corresponding pulses into the power supply or regulate the voltage of the power supply accordingly. As an alternative or in addition, the signal transmitter can be designed to transmit control signals by radio.
Der Signalgeber kann eine Puf ferbatterie umfassen, um auch bei Wegfall der Energieversorgung noch Steuerungssignal aussenden zu können . The signal transmitter can include a buffer battery so that it can still send out a control signal even if the power supply fails.

In Figur la ist ein erstes Aus führungsbeispiel eines erfindungsgemäßen Beleuchtungselementes 1 in isometrischer Darstellung gezeigt . Figur 1b zeigt das Beleuchtungssystem 1 in einer Seitenansicht . FIG. 1a shows a first exemplary embodiment of a lighting element 1 according to the invention in an isometric representation. FIG. 1b shows the lighting system 1 in a side view.
Das Beleuchtungselement 1 umfasst eine flexible Kunststof f folie als flächiges Substrat 2 mit einer Grundfläche von 15 X 45 mm2 bei einer Dicke von 0,2 mm . Auf der ersten Seite 3 des Substrats 2 ist voll flächig eine Klebeschicht 4 vorgesehen, mit der das Beleuchtungselement 1 an einer geeigneten Fläche einer Tragstruktur (nicht dargestellt ) befestigt werden kann . Durch die Klebeschicht 4 mit einer Dicke von 0,1 mm ist dieThe lighting element 1 comprises a flexible plastic film as a flat substrate 2 with a base area of 15×45 mm 2 and a thickness of 0.2 mm. On the first side 3 of the substrate 2, an adhesive layer 4 is provided over the entire surface, with which the lighting element 1 can be attached to a suitable surface of a support structure (not shown). By the adhesive layer 4 with a thickness of 0.1 mm is the
Grundfläche selbstklebend . Auf der zweiten Seite 5 des Substrats 2 sind diverse , nachfolgend noch erläuterte Komponenten 6- 12 per Tintenstrahldruckverfahren auf getragen . Aufgrund des Druckverfahrens und der geringen Höhe von max . 0,2 mm der einzelnen Komponenten wird die Flexibilität des Substrats 2 nur geringfügig beeinträchtigt . Das Substrat 2 und in der Folge das BeleuchtungselementBase self-adhesive. On the second side 5 of the substrate 2 , various components 6 - 12 , which will be explained below, are applied using an inkjet printing process. Due to the printing process and the low height of max. 0.2 mm of the individual components, the flexibility of the substrate 2 is only slightly impaired. The substrate 2 and subsequently the lighting element
I bleiben flexibel verformbar, um sich so an eine beliebige Fläche einer Trägerstruktur anpassen zu können . I remain flexibly deformable in order to be able to adapt to any surface of a support structure.
Auf der zweiten Seite 5 des Substrats sind drei Leuchtelemente 6 auf gedruckt . Bei den Leuchtelementen 6 handelt es sich um gedruckte OLEDs die über ebenfalls gedruckte Leiterbahnen 11 mit einer Steuerungsschaltung 7 verbunden sind, welche die Energiezufuhr zu den Leuchtelementen 6 einzeln steuern kann . Die Steuerungsschaltung 7 ist mit einer gedruckten Antenne 8 verbunden, über welche Steuerungssignale empfangen und Statusmitteilungen von der Steuerungsschaltung 7 versendet werden können . Über entsprechende Steuerungssignale können die Leuchtelemente 6 beliebig aktiviert und deaktiviert werden . Auch kann ein Steuerungssignal für eine Statusabfrage vorgesehen sein, auf welches hin die Steuerungsschaltung 7 den aktuellen Betriebs zustand der Beleuchtungseinheit 1 über die Antenne 8 aussendet . Three light-emitting elements 6 are printed on the second side 5 of the substrate. The light-emitting elements 6 are printed OLEDs, which are also connected via printed conductor tracks 11 to a control circuit 7, which can control the energy supply to the light-emitting elements 6 individually. The control circuit 7 is connected to a printed antenna 8, via which control signals can be received and status messages can be sent from the control circuit 7. The lighting elements 6 can be activated and deactivated as desired via corresponding control signals. A control signal for a status query can also be provided, upon which the control circuit 7 transmits the current operating state of the lighting unit 1 via the antenna 8 .
Die zum Betrieb der Steuerungsschaltung 6 und der Leuchtelemente 6 erforderliche Energie wird der Steuerungsschaltung 6 über gedruckte Leitungen 11 von der Ladeschaltung 9 zugeführt . Die Ladeschaltung 9 ist mit einem aufladbaren Energiespeicher 10 verbunden und lässt sich weiterhin zum Rand des Substrats 2 geführte und dort zu Kontakt flächen 12 erweiterte LeiterbahnenThe energy required to operate the control circuit 6 and the light-emitting elements 6 is supplied to the control circuit 6 by the charging circuit 9 via printed lines 11 . The charging circuit 9 is connected to a chargeable energy store 10 and can continue to be guided to the edge of the substrate 2 and there to contact surfaces 12 extended traces
I I mit einer externen Energiequelle , bspw . mit dem Bordnetz eines Verkehrs flugzeuges verbinden . Die Ladeschaltung 9 ist dazu ausgebildet , den Energiespeicher 10 im Normalbetrieb vollständig auf zuladen und die Steuerungsschaltung 7 mit extern zugeführter Energie zu versorgen . Erst bei Wegfall der externen Energiequelle werden die Steuerungsschaltung 7 sowie darüber die Leuchtelemente 6 mit Energie aus dem Energiespeicher 10 versorgt . Dabei erfolgt die Energieversorgung durch die Energiespeicher 10 bei etwas geringerer Spannung als die Energieversorgung aus der externen Energiequelle . Die Steuerungsschaltung 6 kann zur Spannungserkennung ausgebildet sein und die Leuchtelemente 6 bei festgestellter geringerer Spannung - die mit dem Aus fall der externen Energiequelle gleichgesetzt werden kann - automatisch zu aktivieren . II with an external energy source, for example. connect to the on-board network of a commercial aircraft. The charging circuit 9 is designed to use the energy store 10 in normal operation fully charged and to supply the control circuit 7 with externally supplied energy. The control circuit 7 and, via it, the light-emitting elements 6 are only supplied with energy from the energy store 10 when the external energy source is lost. In this case, the energy is supplied by the energy store 10 at a somewhat lower voltage than the energy supply from the external energy source. The control circuit 6 can be designed to detect voltage and automatically activate the light-emitting elements 6 when a lower voltage is detected—which can be equated with the failure of the external energy source.
Die zweite Seite 5 des Substrats ist durchgehend - mit Ausnahme des Bereichs um die Kontakt flächen 12 - mit einem transparenten Lack als Schutzbeschichtung 13 überzogen . Die Dicke der Schutzbeschichtung 13 beträgt 0,1 mm, wobei der Lack so gewählt ist , dass die grundsätzliche Flexibilität des Substrats 2 nicht eingeschränkt wird und der Lack auch bei Biegung des Substrats 2 nicht bricht . The second side 5 of the substrate is continuously covered with a transparent lacquer as a protective coating 13 - with the exception of the area around the contact surfaces 12 . The thickness of the protective coating 13 is 0.1 mm, the lacquer being selected in such a way that the basic flexibility of the substrate 2 is not restricted and the lacquer does not break even when the substrate 2 is bent.
In den Randbereichen des Substrats 2 , in denen keine Komponenten 6- 12 angeordnet sind, sind Durchbruchsbereiche 4 für Befestigungselemente (nicht dargestellt ) vorgesehen . Sofern die Klebeschicht 4 zur Befestigung des Beleuchtungselementes 1 nicht ausreicht (bspw . weil die entsprechende Fläche der Tragstruktur schlechte Hafteigenschaften aufweist ) , kann das Beleuchtungselement 1 in den Durchbruchsbereichen 4 durchstoßen werden, um so zusätzlich zur Klebeschicht 4 noch mit Nägeln, Nieten oder Schrauben an der Tragstruktur befestigt zu werden . Breakthrough areas 4 for fastening elements (not shown) are provided in the edge areas of the substrate 2, in which no components 6-12 are arranged. If the adhesive layer 4 is not sufficient for fastening the lighting element 1 (e.g. because the corresponding surface of the supporting structure has poor adhesive properties), the lighting element 1 can be pierced in the perforation areas 4, so that nails, rivets or screws can be used in addition to the adhesive layer 4 to be attached to the supporting structure.
Aus den oben genannten Dicken der einzelnen Schichten des Beleuchtungselementes (Klebeschicht 4 = 0,1 mm, Substrat 2 = 0,2 mm, Komponenten 6- 12 < 0,2 mm und Schutzschicht = 0,1 mm) ergibt sich eine Gesamtdicke von nicht mehr als 0,6 mm . Angesichts der Größe der Grundfläche des Substrats 2 von 15 X 45 mm2 ergibt sich für das in Figur 1 dargestellte Beleuchtungselement 1 ein Verhältnis von dieser Substrat-Grundfläche zu der Dicke des Beleuchtungselementes 1 von From the above thicknesses of the individual layers of the lighting element (adhesive layer 4 = 0.1 mm, substrate 2 = 0.2 mm, components 6-12 < 0.2 mm and protective layer = 0.1 mm) results in a total thickness of not more than 0.6 mm. In view of the size of the base area of the substrate 2 of 15×45 mm 2 , the ratio of this substrate base area to the thickness of the illumination element 1 for the lighting element 1 shown in FIG

Das Gewicht von 6,5 g kann durch Auswahl von Leichtbaumaterialien, aber ggf . auch durch Anpassung der Größe der einzelnen Komponenten 6- 12 , wie bspw . der Leuchtelemente 6 und des Energiespeichers 10 , erreicht werden, wobei selbstverständlich eine ausreichende Leuchtkraft und Energieversorgung für den Notfall sichergestellt bleiben muss . 6.5 g 9 yields . The weight of 6.5 g can be increased by selecting lightweight materials, but if necessary. also by adjusting the size of the individual components 6-12, such as. of the light-emitting elements 6 and the energy store 10, can be achieved, with sufficient luminosity and energy supply for emergencies obviously having to be ensured.

The actual lighting element 1 fully corresponds to that of FIG. 1, which is why reference is made to the above explanations.
An das Beleuchtungselement 1 gemäß Figur 2 ist zusätzlich eine Anschlussleitung 15 vorgesehen, die einstückig mit dem Beleuchtungselement 1 ausgeführt ist . Dazu erstreckt sich das Substrat 2 in der gewünschten Form der Anschlussleitung 15 über das eigentliche Beleuchtungselement 1 hinaus . Die Leiterbahnen 11 sind auf dem Substrat 2 im Bereich der Anschlussleitung 15 fortgeführt und münden in Kontakt fläche 12 am Ende der Anschlussleitung 15 . Sowohl die Klebeschicht 4 als auch die Schutzschicht 13 erstrecken sich einstückig auch über die Anschlussleitung 15 . A connection line 15 is additionally provided on the lighting element 1 according to FIG. For this purpose, the substrate 2 extends in the desired shape of the connection line 15 beyond the actual lighting element 1 . The conductor tracks 11 are continued on the substrate 2 in the area of the connection line 15 and open into the contact surface 12 at the end of the connection line 15 . Both the adhesive layer 4 and the protective layer 13 also extend in one piece over the connection line 15 .

Darüber hinaus sind Antenne 8 und Energiespeicher 10 noch abweichend angeordnet , um Platz für eine Antenne 16 zur drahtlosen Energieübertragung zu schaf fen . Die Antenne 16 ist dabei so ausgebildet , um mit einer geeigneten Spule (nicht dargestellt ) induktiv gekoppelt zu werden, sodass elektrische Energie drahtlos an das Beleuchtungselement 1 übertragen werden und dort , wie zuvor beschrieben, zum Betrieb der Steuerungsschaltung 7 und der Leuchtelemente 6 , aber auch zum Laden des Energiespeichers 10 genutzt werden kann . In the lighting element 1 according to FIG. 3, the control circuit 7 and the charging circuit 9 are integrated into a single circuit 7 , 9 . In addition, antenna 8 and energy store 10 are arranged differently in order to create space for an antenna 16 for wireless energy transmission. The antenna 16 is designed to be inductively coupled to a suitable coil (not shown), so that electrical energy can be transmitted wirelessly to the lighting element 1 and there, as previously described, to operate the control circuit 7 and the lighting elements 6 , but can also be used to charge the energy store 10 .
Es ist selbstverständlich auch möglich, die beiden Antennen 8 , 16 miteinander zu kombinieren und als eine einzelne Antenne aus zubilden . Of course, it is also possible to combine the two antennas 8, 16 with one another and to design them as a single antenna.

Die Abstände zwischen den einzelnen Anschlussmöglichkeiten 112 ist dabei derart gering gewählt , dass sich unabhängig von der tatsächlichen Position einzelner Sitzreihen 103 in dem Passagierbereich 101 immer eine Anschlussmöglichkeit 112 für das an der Sitzreihe 103 angeordnete Beleuchtungselement 1 in der Nähe befindet . An energy supply infrastructure 110 is provided along the floor of the passenger area 101, which in this exemplary embodiment comprises a cable run 111 extending along the passenger area 101, on which connection options 112 for the supply lines 113 to the lighting elements 1 are provided at regular intervals.

Entlang der Passagierkabine 101 sind als Teil der Energieversorgungsinfrastruktur 110 Sendemodule 114 vorgesehen, die in Abhängigkeit der Spannung im Leitungsstrang 111 nicht nur drahtlos Energie übertragen, sondern auch Steuerungssignale aussenden, die von den Beleuchtungselementen 1 verarbeitet werden können . Die Energieübertragung erfolgt dabei im Nahfeld, wobei die Sendemodule 114 so angeordnet sind, dass die Sitzreihen 103 mit den an der Sitzstruktur 102 angeordneten Beleuchtungselementen 1 an beliebigen Positionen innerhalb des Passagierbereichs 101 angeordnet werden und die entsprechenden Beleuchtungselemente 1 dennoch mit Energie durch die Sendemodule 114 versorgt werden können . Provided along the passenger cabin 101 as part of the energy supply infrastructure 110 are transmission modules 114 which not only wirelessly transmit energy depending on the voltage in the wiring harness 111 but also emit control signals which can be processed by the lighting elements 1 . The energy is transmitted in the near field, with the transmitter modules 114 being arranged in such a way that the seat rows 103 with the lighting elements 1 arranged on the seat structure 102 are arranged at any positions within the passenger area 101 and the corresponding lighting elements 1 are nevertheless supplied with energy by the transmitter modules 114 can become .
