Description

Die Erfindung betrifft Leuchten gemäß dem Oberbegriff des Anspruchs 1, insbesondere Leuchten, welche gegenüber ihrer Umgebung mechanisch und/oder elektrisch isoliert sein müssen.The invention relates to luminaires according to the preamble of claim 1, in particular Luminaires which are mechanically and / or electrically isolated from their environment have to.

Bei derartigen Leuchten müssen die Anschlüsse der Lichtquelle gegenüber Feuchtigkeit und/oder gegen einen elektrischen Überschlag bzw. Funken isoliert werden.In such lights, the connections of the light source to moisture and / or isolated against electrical flashover or sparks.

Um die notwendige Dichtigkeit der Leuchte beispielsweise gegen Feuchtigkeit entsprechend einer geforderten Schutzart zu gewährleisten, ist es üblich, die Lichtquelle zusammen mit den zugehörigen elektrischen Komponenten in einem geschlossenen Gehäuse unterzubringen, das über ein entsprechendes Dichtsystem verfügt. Zum Wechsel der Lichtquelle muß dieses abgedichtete Gehäuse geöffnet und anschließend wieder geschlossen werden, was zu einer Beeinträchtigung der Dichtigkeit führen kann. Um zu gewährleisten, daß ein elektrischer Anschluß und auch ein Wechsel der Lichtquelle möglich ist, ohne daß die entsprechende Schutzart oder Schutzkategorie beeinträchtigt wird, ist ein hoher konstruktiver Aufwand nötig. Entsprechendes gilt auch für Leuchten, die z.B. gegen das Eindringen von brennbaren Gasen geschützt sein müssen, um einer Explosion vorzubeugen. All diesen Leuchten nach dem Stand der Technik gemeinsam ist, daß die Lichtquelle zusammen mit den zugehörigen elektrischen Komponenten in einem dichten, abgeschlossenen Gehäuse angeordnet ist, so daß sich die Lichtquelle im Falle eines Defekts nicht oder nur mit verhältnismäßig großem Aufwand auswechseln läßt.To the necessary tightness of the lamp, for example, against moisture accordingly To ensure a required degree of protection, it is customary, the light source together with the associated electrical components in a closed housing, the has a corresponding sealing system. To change the light source must be sealed Housing open and then closed again, causing an impairment the tightness can lead. To ensure that an electrical connection and a change of the light source is possible without the corresponding degree of protection or Protection category is impaired, a high design effort is needed. The same also applies to luminaires which are e.g. protected against the penetration of combustible gases have to be in order to prevent an explosion. All these lights according to the state of Technique in common is that the light source together with the associated electrical Components is arranged in a sealed, sealed housing, so that the Light source in case of failure or replace only with relatively great effort leaves.

Die Aufgabe der vorliegenden Erfindung ist es, eine Leuchte zur Verfügung zu stellen, die bei einem geringen konstruktiven Aufwand auch als Leuchte einer hohen Schutzart einsetzbar ist. Außerdem soll eine möglichst kleine, kompakte Bauform ermöglicht werden.The object of the present invention is to provide a luminaire available at a small design effort can also be used as a luminaire of a high degree of protection. In addition, the smallest possible, compact design should be possible.

Die Erfindung schlägt zur Lösung dieses Problems vor, die Energieübertragung zum Leuchtmittel durch Induktion zu erzeugen, was sowohl elektrische als auch magnetische Induktion einschließt. Auf diese Weise ist es möglich, die elektrischen Komponenten einerseits und das Leuchtmittel andererseits als von einander getrennte, abgedichtete Einheiten, z.B. jeweils als gekapselte Einheiten, vorzusehen, was den Leuchtmittelwechsel erheblich vereinfacht.The invention proposes to solve this problem, the energy transfer to the bulb by induction, causing both electrical and magnetic induction includes. In this way it is possible, the electrical components on the one hand and the On the other hand, as separate sealed units, e.g. each as encapsulated units to provide, which greatly simplifies the lamp replacement.

Durch die Verwendung einer induktiven Kopplung entfallen alle Schwierigkeiten, welche die mechanischen verbundenen elektrischen Kontakte mit sich bringen. Insbesondere lassen sich die Baugruppen so kapseln, daß auch Leuchten höherer Schutzart problemlos realisiert werden können. Außerdem besteht die Möglichkeit, bei Leuchten mit geringer Leistungsaufnahme eine räumlich kompakte Bauform zu realisieren. By using an inductive coupling eliminates all the difficulties that the involve mechanically connected electrical contacts. In particular, can be Encapsulate the modules so that luminaires with a higher degree of protection can be easily realized can. There is also the possibility of low power lamps to realize a spatially compact design.

In einer Ausführungsform der Erfindung wird die magnetische Energieübertragung zwischen einer Basiseinheit und der Leuchtmitteleinheit durch magnetische Induktion erzielt. Dazu befinden sich in den beiden Baugruppen jeweils mindestens eine Spule, die von einem gemeinsamen Magnetfluß durchsetzt werden. Durch Anlegen eines elektrischen Wechselstromes an einer der Spulen wird in der anderen Spule eine Wechselspannung induziert, durch die eine oder mehrere Lampen oder andere Lichtquellen, z.B. LEDs, versorgt werden können.In one embodiment of the invention, the magnetic energy transfer between a base unit and the lamp unit achieved by magnetic induction. To find it in each case at least one coil in the two modules, from a common Magnetic flux are interspersed. By applying an alternating electric current one of the coils is induced in the other coil an alternating voltage through which a or several lamps or other light sources, e.g. LEDs, can be supplied.

In einer bevorzugten Ausführungsform wird der Magnetfluß durch einen Kern übertragen, der von den beiden Spulen umschlossen wird. Dieser Kern besitzt eine magnetflußbündelnde Eigenschaft, so daß die Effizienz der Energieübertragung zwischen den Spulen wesentlich erhöht wird. Der Kern kann ein- oder mehrteilig sein. Im Fall einer einteiligen Ausbildung ist dieser Kern in das Leuchtmittelteil oder das Versorgungsteil integriert und bildet einen Vorsprung, auf welchen das jeweils andere Teil, das im Bereich seiner Spule einen entsprechenden, nach außen offenen Hohlraum besitzt, aufgesetzt werden kann. Auf diese Weise läßt sich eine einfache Steckverbindung realisieren. Die Ummantelung des Kerns bzw. die Auskleidung des Hohlraums kann dabei mit beispielsweise form- oder kraftschlüssigen Verbindungselementen versehen sein, beispielsweise mit einem Schraubgewinde, so daß ein fester Sitz des Leuchtmittelteils an dem Versorgungsteil gewährleistet ist. Dabei können statt einer Schraubverbindung auch andere Verbindungsarten, beispielsweise eine Bajonettverbindung, eine Klemmverbindung oder eine Rastverbindung, verwendet werden.In a preferred embodiment, the magnetic flux is transmitted through a core which is enclosed by the two coils. This core has a magnetic flux bundling property, so that the efficiency of energy transfer between the coils substantially increased becomes. The core can be one or more parts. In the case of a one-piece education is this core is integrated into the luminaire part or the supply part and forms a projection, on which the other part, in the region of its coil a corresponding, outwardly open cavity has, can be placed. In this way can be realize a simple plug connection. The sheathing of the core or the lining The cavity can be used with, for example, positive or non-positive connection elements be provided, for example with a screw thread, so that a tight fit of Lamp part is guaranteed to the supply part. In this case, instead of a screw connection Other types of connections, such as a bayonet connection, a Clamping connection or a locking connection can be used.

Der Kern kann allerdings auch mehrteilig ausgebildet sein, wobei dem Versorgungsteil und dem Leuchtmittelteil jeweils ein Teil des Kerns zugeordnet ist, so daß die beiden Teile im zusammengesetzten Zustand der Leuchte näherungsweise einen durchgängigen Kern bilden, der bei einer bevorzugten Ausführungsform lediglich durch die Isolation unterbrochen ist, welche die beiden Teile des Kerns umgibt. Auf diese Weise läßt sich ein annähernd geschlossener Kern realisieren, was die Energieübertragung verbessert. Der Kern kann stabförmig oder auch eine andere Form, zum Beispiel die eines geschlossenen Jochs oder Torus, haben. Die spezifische elektrische Leitfähigkeit des Kerns muß klein sein, damit Wirbelstromverluste vermieden werden. Für die Übertragung kleiner Leistungen benutzt man bevorzugt Ferritkerne. Für höhere Leistungen kann man auch Eisenkerne, bevorzugt in Form von einander isolierten Blechen, verwenden.However, the core can also be designed in several parts, wherein the supply part and each part of the core is assigned to the lamp part, so that the two parts in assembled state of the lamp approximately form a continuous core, which in a preferred embodiment is interrupted only by the insulation, which surrounds the two parts of the core. In this way, an approximately closed Core, which improves the energy transfer. The core can be rod-shaped or another shape, for example, that of a closed yoke or torus. The specific electrical conductivity of the core must be small, so that eddy current losses be avoided. For the transmission of small powers, it is preferable to use ferrite cores. For higher powers one can also iron cores, preferably isolated in the form of each other Sheet metal, use.

Die Erfindung kann die Verwendung von Leuchtmitteln vorsehen, die eine Leistungsaufnahme von weniger als 5 Watt, bevorzugt etwa 1 Watt, besitzen. Als Leuchtmittel können insbesondere LEDs vorgesehen sein, die eine verhältnismäßig geringe Leistungsaufnahme haben.The invention may provide for the use of bulbs that consume power less than 5 watts, preferably about 1 watt. In particular, as a light source LEDs are provided, which have a relatively low power consumption.

Um die für den Betrieb der Leuchtmittel erforderliche Spannung bereit zu stellen, gibt es verschiedene Möglichkeiten. Eine Möglichkeit besteht darin, das Verhältnis der Windungen der Spulen in dem Versorgungsteil und dem Leuchtmittelteil so aufeinander abzustimmen, daß die Versorgungsspannung des Versorgungsteils auf die entsprechende Betriebsspannung für das Leuchtmittel umgespannt wird. Es kann auch vorgesehen sein, daß in dem Leuchtmittelteil eine geeignete Elektronik vorgesehen ist, um die von der Spule des Leuchtmittelteils gelieferte Spannung an die Betriebsspannung des Leuchtmittels anzupassen. Selbstverständlich ist es auch möglich, die Versorgungsspannung des Versorgungsteils entsprechend der erforderlichen Betriebsspannung des Leuchtmittels zu regeln. Die vorangehend genannten Möglichkeiten könnten natürlich auch kombiniert werden. Insgesamt ist es also möglich, die Versorgungsspannung des Leuchtmittels über das Versorgungsteil, in dem Leuchtmittelteil oder durch die Eigenschaften der Energieumwandlungseinrichtung festzulegen.In order to provide the voltage required for the operation of the lamps, there are various Options. One possibility is the ratio of the turns of the Coils in the supply part and the illuminant part to match so that the supply voltage of the supply part to the corresponding operating voltage for the light source is re-clamped. It can also be provided that in the lamp part a suitable electronics is provided to those supplied by the coil of the lamp part Adjust voltage to the operating voltage of the lamp. Of course It is also possible, the supply voltage of the supply part according to the required Operating voltage of the lamp to regulate. The above possibilities could of course be combined. Overall, it is possible, the supply voltage of the lamp via the supply part, in the lamp part or determined by the properties of the energy conversion device.

Gemäß einer bevorzugten Ausführungsform wird das Versorgungsteil mit einer Wechselspannung betrieben, deren Frequenz deutlich, typischerweise zwei bis drei Größenordnungen oder mehr, über der normalen Netzfrequenz liegt. Gemäß einer Ausführungsform der Erfindung werden Frequenzen im Bereich von 1 kHz bis 100 kHz verwendet. Auf diese Weise werden Übertragungsverluste minimiert.According to a preferred embodiment, the supply part with an alternating voltage operated, their frequency significantly, typically two to three orders of magnitude or more, is above the normal line frequency. According to one embodiment of the The invention uses frequencies in the range of 1 kHz to 100 kHz. In this way Transmission losses are minimized.

Die erfindungsgemäße Leuchte kann auch vorteilhaft zu einem System von mehreren Leuchten gekoppelt werden. In diesem Fall ist es technisch besonders einfach, wenn die Versorgungsteile über eine gemeinsame Netzleitung, zum Beispiel parallel geschaltet, versorgt werden. The luminaire according to the invention can also be advantageous to a system of several lights be coupled. In this case, it is technically particularly easy when the supply parts be supplied via a common power line, for example, connected in parallel.

Die Baugruppen der erfindungsgemäßen Leuchte lassen sich unabhängig voneinander vollständig isolieren, da das Herausführen von offenliegenden elektrischen Kontakten durch die erfindungsgemäße Art der Energieübertragung nicht mehr notwendig ist. Auf diese Weise lassen sich einfach feuchtigkeitsgeschützte oder gasgeschützte Leuchten herstellen, deren Dichtsystem auch einer hohen Schutzart genügt. Gemäß einer bevorzugten Ausführungsform der Erfindung sind das Versorgungsteil und das Basisteil nach außen isoliert und bilden jeweils eine gekapselte Einheit.The modules of the lamp according to the invention can be completely independent of each other isolate, as the lead out of exposed electrical contacts through the inventive type of energy transfer is no longer necessary. In this way can be easily produce moisture-proof or gas-protected lights whose Sealing system also meets a high degree of protection. According to a preferred embodiment According to the invention, the supply part and the base part are insulated to the outside and form respectively an encapsulated unit.

Gemäß einer Ausführungsform der Erfindung wird das Leuchtmittelteil in einer erfindungsgemäßen Leuchte wie eine herkömmliche Lampe verwendet. Dies bedeutet, daß optische Elemente, wie Reflektoren, lichtbrechende Elemente und dergleichen, zumindest teilweise außerhalb des Leuchtmittelteils vorgesehen sind. Beispielsweise kann vorgesehen sein, daß das Leuchtmittelteil von einem Reflektor oder einer anderen optischen Einrichtung umgeben ist oder anderweitig mit dieser/diesen zusammenwirkt, welche das Licht zu einer Lichtaustrittsfläche der Leuchte lenkt. Gemäß einer anderen Ausführungsform der Erfindung kann vorgesehen sein, daß das Leuchtmittelteil, bis auf die Stromversorgung, die über das Versorgungsteil erfolgt, als komplette Leuchte mit den entsprechenden optischen Elementen und der erforderlichen Elektrik bzw. Elektronik ausgebildet ist. Selbstverständlich sind auch Mischformen möglich, bei denen ein Teil der Elektronik und/oder der optischen Elemente in dem Leuchtmittelteil vorgesehen ist und ein Teil dieser Elemente außerhalb des Leuchtmittelteils angeordnet ist. Dabei ist zu beachten, daß eine Leuchte im Sinne dieser Anmeldung auch eine oder mehrere elektrische Komponenten, wie die Stromzuleitung, und insbesondere das Versorgungsteil umfaßt. Eine erfindungsgemäße Leuchte kann also aus einem Versorgungsteil und einem darin eingesteckten Leuchtmittelteil bestehen, in welchem alle restlichen Komponenten, wie Reflektoren, Regelelektronik usw. integriert sind, ähnlich wie dies teilweise bei Niedervolt-Halogenleuchten praktiziert wird, die als komplete Leuchteneinheit, inklusive Reflektor, geliefert werden. According to one embodiment of the invention, the luminous means part in an inventive Lamp used like a conventional lamp. This means that optical Elements such as reflectors, refractive elements, and the like, at least in part are provided outside the lamp part. For example, it can be provided that the illuminant part surrounded by a reflector or other optical device is or otherwise interacts with this / these, which the light to a light exit surface the light directs. According to another embodiment of the invention be provided that the lamp part, except for the power supply, via the supply part takes place as a complete luminaire with the corresponding optical elements and the required electrics or electronics is formed. Of course, also mixed forms possible in which a part of the electronics and / or the optical elements in the Light-emitting part is provided and a part of these elements outside of the bulb part is arranged. It should be noted that a lamp within the meaning of this application also a or a plurality of electrical components, such as the power supply line, and in particular the supply part includes. A luminaire according to the invention can therefore consist of a supply part and a lamp part inserted therein, in which all the remaining components, as reflectors, control electronics, etc. are integrated, similar to this partially at Low-voltage halogen lights are used as a complete lighting unit, including reflector, to be delivered.

Die Erfindung kann insbesondere vorsehen, daß ein erfindungsgemäßes Leuchtmittelteil ein oder mehrere Reflektoren und/oder ein oder mehrere lichtbrechende Elemente aufweist, die einer oder mehreren Lichtquellen zugeordnet sind. Beispielsweise kann bei einem erfindungsgemäßen Leuchtmittelteil eine Abdeckung für die Lichtaustrittsfläche mit einer prismatischen Struktur, zum Beispiel zur Gestaltung der Lichtstärkeverteilungskurve, vorgesehen sein. Weitere Beispiele solcher lichtbrechenden Elemente sind Linsen oder Prismen, die an der Lichtaustrittsfläche oder im Sinne des Strahlengangs vor der Lichtaustrittsfläche innerhalb der Leuchtmitteleinheit vorgesehen sind.The invention may provide that a luminous means part according to the invention one or more having optical elements associated with one or more light sources.

Das in Fig. 1 und 2 schematisch dargestellte Versorgungsteil ist bei dieser Ausführungsform als gekapselte Einheit ausgebildet und weist als wesentliche Bestandteile eine Spule 4 und eine Netzverbindung 3 zur Versorgung der Spule auf. Die Figuren 1 und 2 zeigen einen Schnitt durch die Spule, wobei die Längsachse der Spule in der Bildebene liegt. Wie insbesondere aus Fig. 2 ersichtlich ist, weist das Versorgungsteil 1 bei dieser Ausführungsform eine Bohrung 5 auf, welche zumindest an einer Seite offen ist und mit der Bohrung der Spule zusammenfällt oder sich zumindest innerhalb dieser erstreckt. Das Leuchtmittelteil 2 weist mehrere Leuchtdioden-Module 10 auf, welche über Leitungen 12 mit den Anschlüssen einer Spule 14 des Leuchtmittelteils 2 verbunden sind. Die Bohrung dieser Spule 14 wird von einem Ferritkern 16 durchsetzt, der von dem Leuchtmittelteil 2 vorsteht und mit einer Schutzummantelung 18 umgeben ist. Der dadurch gebildete Vorsprung 20 hat einen Durchmesser, welcher dem Durchmesser der Bohrung 5 entspricht und eine Länge, welche der Länge der Bohrung 5 entspricht. Die Schutzummantelung 18 umgibt alle Komponenten des Leuchtmittelteils 2, so daß insgesamt eine gekapselte Einheit entsteht. Im Bereich der Leuchtdioden 10 ist in der Schutzummantelung 18 ein Fenster 22 vorgesehen, durch welches das Licht der Dioden austreten kann.The supply part shown schematically in FIGS. 1 and 2 is in this embodiment formed as an encapsulated unit and has as essential components a coil 4 and a network connection 3 for supplying the coil. Figures 1 and 2 show a Section through the coil, wherein the longitudinal axis of the coil lies in the image plane. In particular From Fig. 2 it can be seen, has the supply part 1 in this embodiment a bore 5 which is open at least on one side and with the bore of the coil coincides or at least extends within this. The illuminant part 2 has a plurality of light-emitting diode modules 10, which via lines 12 to the terminals of a Coil 14 of the lamp part 2 are connected. The bore of this coil 14 is of a Ferrite core 16 passes, which protrudes from the lamp part 2 and with a Protective sheath 18 is surrounded. The projection 20 thus formed has a diameter, which corresponds to the diameter of the bore 5 and a length which corresponds to the length the bore 5 corresponds. The protective sheath 18 surrounds all components of the Illuminant part 2, so that a total of an encapsulated unit is formed. In the field of light-emitting diodes 10, a window 22 is provided in the protective sheath 18 through which the Light of the diodes can escape.

Im montierten Zustand der Leuchte kommt in der Bohrung 5 der Spule 4 der Ferritkern 16 zu liegen. Da dieser mit der Leuchtmitteleinheit 2 fest verbundene Spulenkern 16 sich bis in die Spule 14 erstreckt, überträgt er den magnetischen Fluß von der stromdurchflossenen Spule 4 in das Leuchtmittelteil 2. Dort wird der magnetische Fluß wieder in eine Spannung umgewandelt, indem durch den magnetischen Fluß in der Spule 6 eine Spannung induziert wird, welche den Leuchtdioden 10 zugeführt wird. In der gezeigten Ausführungsform besteht das Leuchtmittel aus mehreren LED-Modulen 10. Gegebenenfalls kann auch eine einzige Lichtquelle vorgesehen sein. Das Verhältnis der Wicklungszahlen der Spulen 4 und 14 sind so aufeinander abgestimmt, daß die Spannung, welche über die Netzleitung 3 an der Basiseinheit anliegt, auf einen Wert transformiert wird, der zum Betrieb der LED-Module 10 geeignet ist. Die Spulen 4 und 14 wirken dabei wie die Primär- und Sekundärseite eines Transformators. Das Leuchtmittelteil 2 ist vollständig mit einer Schutzummantelung 18 versehen, welche die Leuchtmitteleinheit 2 vollständig nach außen elektrisch isoliert. Da auch das Versorgungsteil 1 entsprechend gekapselt ist, bilden das Leuchtmittelteil und das Basisteil zusammen eine Leuchte, deren Komponenten sämtlich nach außen isoliert sind und dabei, je nach den Anforderungen der Schutzklasse, gegen Feuchtigkeit und/oder gegen das Eindringen von Gasen geschützt sind. Auf diese Weise lassen sich auch konstruktiv sehr einfach Leuchten mit einer hohen Schutzkategorie betreffend den Schutz gegen elektrischen Schlag verwirklichen, beispielsweise Leuchten der Kategorie II oder III gemäß DIN-EN 60598-1.In the assembled state of the lamp comes in the bore 5 of the coil 4 of the ferrite core 16 lie. Since this firmly connected to the light-emitting unit 2 spool core 16 extends into the Coil 14 extends, it transmits the magnetic flux from the current-carrying coil 4th in the illuminant part 2. There, the magnetic flux is converted back into a voltage, in that a voltage is induced by the magnetic flux in the coil 6, which is the light-emitting diodes 10 is supplied. In the embodiment shown, this is Illuminant from several LED modules 10. Optionally, a single light source be provided. The ratio of the number of turns of the coils 4 and 14 are so mutually matched, that the voltage, which via the power line 3 to the base unit is applied, is transformed to a value that is suitable for operation of the LED modules 10. The coils 4 and 14 act like the primary and secondary sides of a transformer. The illuminant part 2 is completely provided with a protective sheath 18, which the Bulb unit 2 completely electrically insulated to the outside. As well as the supply part 1 is encapsulated accordingly form the light-emitting means and the base part together one Luminaire whose components are all insulated to the outside and, depending on the requirements the protection class, against moisture and / or against the ingress of gases are protected. In this way, it is also very easy to construct lights with one high protection category concerning the protection against electric shock, for example Luminaires of category II or III according to DIN-EN 60598-1.

In der gezeigten Ausführungsform werden die Leuchtmitteleinheit und die Basiseinheit einfach durch Ineinanderstecken verbunden. An dieser Stelle kann aber auch beispielsweise eine Schraubverbindung oder eine andere Art der Verbindung, die für Lampenfassungen verwendet wird, vorgesehen sein, so daß die Leuchtmitteleinheit ähnlich wie eine konventionelle Lampe gehandhabt werden kann.In the illustrated embodiment, the lighting unit and the base unit become simple connected by nesting. At this point but also, for example, a Screw connection or another type of connection used for lamp holders is provided, so that the lighting unit similar to a conventional Lamp can be handled.

Fig. 3 zeigt ein Leuchtensystem, das aus mehreren Leuchten gemäß den Fig. 1 und 2 besteht. Die Spulen der Basiseinheiten sind dabei parallel an einer gemeinsamen Versorgungsleitung 30 geschaltet. Auf diese Weise können aus mehreren, an sich lichtschwachen Leuchtmitteln Leuchten mit einer höheren Lichtleistung aufgebaut werden. Eine andere Anwendungsmöglichkeit wäre zum Beispiel die Verwendung als Kette von Orientierungsleuchten. Die in Fig. 3 gezeigte Anordnung hat gegenüber einer Schaltung von herkömmlichen Lampenfassungen den Vorteil, daß in dem Fall, daß ein Leuchtmittel ausfällt oder herausgenommen wird, die verbleibenden Leuchtmittel funktionsfähig bleiben.Fig. 3 shows a lighting system consisting of several lights according to FIGS. 1 and 2. The coils of the base units are parallel to a common supply line 30 switched. In this way, from several, in itself faint bulbs Lights are built with a higher light output. Another application For example, it would be used as a chain of orientation lights. The in Fig. 3 shown arrangement has compared to a circuit of conventional lamp sockets the advantage that in the event that a bulb fails or is taken out, the remaining bulbs remain functional.

Zahlreiche Abwandlungen der vorangehend beschriebenen Leuchten sind möglich. Beispielsweise kann die Geometrie der Induktionsspulen und deren Kern eine andere Form besitzen. Insbesondere zur Übertragung höherer Leistungen wäre es sinnvoll, den Spulenkern in wenigstens zwei Teilen auszubilden, so daß diese im montierten Zustand der Leuchte ein geschlossenes Joch oder einen Torus bilden.Numerous modifications of the luminaires described above are possible. For example For example, the geometry of the induction coils and their core may have a different shape. In particular, for transmitting higher power, it would be useful to the coil core in form at least two parts, so that these in the assembled state of the lamp a closed Yoke or a torus.
