Abstract

The present invention relates to an operation or examination lighting unit with at least one first and at least one second light source which have a common optical system, and a control unit which can control the brightness of the first light source separately from the brightness of the second light source, and which by means of variable control of the brightness of the first and of the second light source causes a change of geometry, in particular a displacement and/or variable focusing of the total light field produced by the operation or examination lighting unit.

Description

Die vorliegende Erfindung betrifft eine Operations- und Untersuchungsleuchte.The present invention relates to a surgical and examination light.

Operations- oder Untersuchungsleuchten kommen dabei im medizinischen Bereich z.B. zur Ausleuchtung der Operationsstelle oder der zu untersuchenden Stelle zum Einsatz. Dabei ist es nötig, das von der Leuchte erzeugte Lichtfeld zu verändern und/oder unterschiedlich zu fokussieren, um das Lichtfeld an die spezifischen Bedürfnisse während der Operation oder Untersuchung anzupassen.Surgical or examination lights are used in the medical field, e.g. to illuminate the surgical site or the area to be examined. It is necessary to change the light field generated by the lamp and / or to focus it differently in order to adapt the light field to the specific needs during the operation or examination.

In bekannten Operations- oder Untersuchungsleuchten kamen bisher zur Fokussierung bzw. Lichtfeldverstellung lediglich mechanische Lösungen zum Einsatz.In known surgical or examination lights, only mechanical solutions have been used to date for focusing or adjusting the light field.

Üblicherweise wird zur Fokussierung bzw. Lichtfeldverstellung in den so genannten "Einaugenleuchten" mit nur einer Lichtquelle das Leuchtmittel innerhalb des Reflektors auf der optischen Achse des Gesamtsystems verschoben, was eine Vergrößerung bzw. Verkleinerung des sich ergebenden Lichtfeldes ergibt.Usually, for focusing or adjusting the light field in the so-called "single-eye lights" with only one light source, the illuminant is shifted within the reflector on the optical axis of the overall system, which results in an enlargement or reduction of the resulting light field.

Bei Mehraugenleuchten, bei denen die Leuchte für die OP-Feld-Beleuchtung aus mehreren Einzelscheinwerfern gebildet wird, wird zur Erzielung eines kleinen Lichtfeldes das Licht jedes einzelnen Scheinwerfers in einen Punkt konzentriert. Im Gegensatz dazu wird das Lichtfeld vergrößert, indem durch ein mechanisches Schwenken und erneute Ausrichtung der Einzelleuchten ein größeres Feld bestrahlt wird. In diesem Fall wird eine teilweise Überschneidung des Lichtfeldes jedes einzelnen Scheinwerfers erzielt, so daß sich ein großes Lichtfeld mit geringerer Lichtstärke ergibt.In multi-eye lights, in which the light for the operating theater field lighting is made up of several individual headlights, the light from each individual headlight is concentrated in one point in order to achieve a small light field. In contrast to this, the light field is enlarged by irradiating a larger field by mechanically pivoting and realigning the individual lights. In this case, a partial overlap of the light field of each individual headlight is achieved, so that a large light field with a lower light intensity results.

Bei beiden Leuchtenvarianten (Einaugenleuchte oder Mehraugenleuchte) ist zur Erzielung des gewünschten Lichtfeldes ein erheblicher mechanischer Aufwand zu leisten, welcher auch dementsprechend kostenintensiv ist. Auch bauen die Lampen durch die mechanische Einrichtung (Handverstellung oder motorische Verstellung) zur Fokussierung sehr groß, wobei sie zumindest für die manuelle Verstellung einen großen, vom Operateur zu bedienenden Sterilhandgriff aufweisen müssen. Eine motorische Verstellung benötigt wiederum viel Bauraum für ihre Komponenten wie z. B. den Antriebsmotor, das Getriebe, Umlenkgetriebe, die Steuerung und das Gestänge. Die bekannten Leuchten sind zudem durch die für die mechanische Verstellung erforderlichen Komponenten und beweglichen Elemente wie z. B Gleitführung, Führung, Abdichtung, Ausgleichselemente und Bedienhandgriffe schlecht zu reinigen und zu desinfizieren. Auch sind diese in der Bedienung und Wartung problematisch, wobei die Verstellung zudem wertvolle Zeit kostet.With both lamp variants (single-eye lamp or multi-eye lamp), a considerable mechanical effort has to be made in order to achieve the desired light field, which is also correspondingly cost-intensive. Also build the lamps very large due to the mechanical device (manual adjustment or motorized adjustment) for focusing, and at least for manual adjustment they must have a large sterile handle to be operated by the surgeon. A motorized adjustment, in turn, requires a lot of installation space for its components such as B. the drive motor, the gearbox, deflection gear, the control and the linkage. The known lights are also due to the components and movable elements required for mechanical adjustment such. B Slideway, guide, seal, compensation elements and operating handles are difficult to clean and disinfect. These are also problematic in terms of operation and maintenance, and the adjustment also costs valuable time.

Operationsleuchten mit mehreren Lichtquellen sind beispielsweise aus der EP 1 722 157 A1 , der US 2004/0129860 A1 und der DE 10 2006 004 995 A1 bekannt.Operating lights with multiple light sources are, for example, from the EP 1 722 157 A1 , of the US 2004/0129860 A1 and the DE 10 2006 004 995 A1 known.

In der DE 100 34 594 A1 ist eine zahnärztliche Behandlungsleuchte beschrieben, bei der die Lichtquellen aus mehreren benachbart zueinander angeordneten LEDs besteht, wobei jeweils Gruppen von mehreren LEDs optische Bauelemente zugeordnet sind.In the DE 100 34 594 A1 describes a dental treatment light in which the light sources consists of several LEDs arranged adjacent to one another, with optical components being assigned to groups of several LEDs.

Aufgabe der vorliegenden Erfindung ist es deshalb, eine Operations- oder Untersuchungsleuchte zur Verfügung zu stellen, welche die geschilderten Nachteile des Standes der Technik überwindet und insbesondere eine einfache und bequem zu bedienende, kostengünstige und raumsparende Verstellung bzw. Fokussierung des Lichtfeldes ermöglicht.The object of the present invention is therefore to provide a surgical or examination lamp which overcomes the disadvantages of the prior art and in particular enables simple and easy-to-use, inexpensive and space-saving adjustment or focusing of the light field.

Erfindungsgemäß wird diese Aufgabe von einer Operations- oder Untersuchungsleuchte gemäß Anspruch 1 gelöst. Diese umfaßt mindestens eine erste und mindestens eine zweite Lichtquelle, welche ein gemeinsames optisches System aufweisen. Des weiteren ist eine Ansteuerungseinheit vorgesehen, welche die Helligkeit der ersten Lichtquelle getrennt von der Helligkeit der zweiten Lichtquelle ansteuern kann und welche jeweils durch unterschiedliche Ansteuerung der Helligkeit der ersten oder zweiten Lichtquelle eine Verstellung der Form und/oder unterschiedliche Fokussierung des von der Operations- oder Untersuchungsleuchte erzeugten Gesamt-Lichtfeldes bewirkt. So können die aufwendigen mechanischen Komponenten und die damit verbundenen oben beschriebenen Probleme entfallen, da sich die Fokussierung bzw. Lichtfeldeinstellung ohne jede beweglichen Elemente einfach über die Einstellung der Helligkeit der ersten und der zweiten Lichtquelle verändern läßt. Eine solche Ansteuerung ist damit im Gegensatz zum Stand der Technik geräuschlos, verschleißfrei, wartungsfrei und verzögerungsfrei. Ebenso ist ein einfach zu reinigendes und zu desinfizierendes Design möglich, da die mechanischen Komponenten entfallen. Zudem ist so ein sehr graziles und kleinbauendes Design möglich. Durch die Verwendung eines gemeinsamen optischen Systems für mehrere Lichtquellen ist es dabei möglich, Kosten und Bauraum zu sparen. Ein solches optisches System kann z. B. eine Linse, ein Reflektor, ein Prisma oder eine Mischung der obigen Bauteile sein bzw. auf einer Mischung der optischen Funktion der obigen Bauteile basieren. Erfindungsgemäß sind die von den Lichtquellen erzeugten Einzel-Lichtfelder in unterschiedliche Richtung ausgerichtete und/oder die Helligkeitsmaxima der von den Lichtquellen erzeugten Einzel-Lichtfelder gegeneinander verschoben. So können durch die unterschiedliche Ausrichtungen der einzelnen Lichtkegel unterschiedliche Lichtfelder erzeugt werden.According to the invention, this object is achieved by a surgical or examination light according to claim 1. This comprises at least one first and at least one second light source, which have a common optical system. Furthermore, a control unit is provided which can control the brightness of the first light source separately from the brightness of the second light source and which, by controlling the brightness of the first or second light source differently, adjusts the shape and / or differently focusses the from the surgical or Examination light generated overall light field causes. The complex mechanical components and the associated problems described above can thus be dispensed with, since the focusing or setting of the light field can be changed without any movable elements simply by setting the brightness of the first and second light sources. In contrast to the prior art, such a control is therefore noiseless, wear-free, maintenance-free and without delay. A design that is easy to clean and disinfect is also possible, since the mechanical components are not required. In addition, a very delicate and compact design is possible. By using a common optical system for several light sources, it is possible to save costs and space. Such an optical system can e.g. B. a lens, a reflector, a prism or a mixture of the above components or based on a mixture of the optical function of the above components. According to the invention, the individual light fields generated by the light sources are aligned in different directions and / or the brightness maxima of the individual light fields generated by the light sources are shifted relative to one another. Different light fields can be generated through the different orientations of the individual light cones.

Die erfindungsgemäße Operations- und Untersuchungsleuchte umfasst zwei oder mehrere erste Lichtquellen und zwei oder mehrere zweite Lichtquellen. Die von mehreren ersten oder zweiten Lichtquellen erzeugten Einzel-Lichtfelder bilden dann ein Teil-Lichtfeld. Dies ermöglicht eine verbesserte Ausleuchtung bzw. ein gleichmäßigeres Lichtfeld und zudem eine größere Flexibilität bei der Verstellung bzw. Fokussierung des Lichtfeldes. Auch können Einzellichtquellen geringerer Leistung zum Einsatz kommen, was konstruktive und preisliche Vorteile hat.The surgical and examination light according to the invention comprises two or more first light sources and two or more second light sources. The individual light fields generated by a plurality of first or second light sources then form a partial light field. This enables improved illumination or a more uniform light field and also greater flexibility in adjusting or focusing the light field. Individual light sources of lower power can also be used, which has structural and price advantages.

Insbesondere gilt dies vorteilhafterweise für die von den ersten und zweiten Lichtquellen erzeugten Lichtfelder, so daß durch die Einstellung der jeweiligen Helligkeiten dieser Lichtfelder das Gesamtlichtfeld verändert oder fokussiert werden kann.In particular, this advantageously applies to the light fields generated by the first and second light sources, so that the overall light field can be changed or focused by setting the respective brightnesses of these light fields.

Jedoch sind auch bei der Verwendung von mehreren ersten bzw. zweiten Lichtquellen die innerhalb der ersten Lichtquellen erzeugten unterschiedlichen Einzel-Lichtfelder vorteilhafterweise ebenso in unterschiedliche Richtungen ausgerichtet bzw. weisen sie gegeneinander verschobene Helligkeitsmaxima auf. Die gegeneinander verschobenen Einzell-Lichtfelder einer Gruppe von Lichtquellen erzeugen so gemeinsam ein größeres Teil-Lichtfeld.However, even when a plurality of first or second light sources are used, the ones generated within the first light sources are different Individual light fields advantageously also aligned in different directions or have brightness maxima that are shifted relative to one another. The individual light fields of a group of light sources, which are shifted relative to one another, thus jointly generate a larger partial light field.

In einer ersten Variante der vorliegenden Erfindung ist das von den ersten Lichtquellen erzeugte Teil-Lichtfeld stärker fokussiert als das von den zweiten Lichtquellen erzeugte Teil-Lichtfeld. So ist es mit der erfindungsgemäßen Operations- oder Untersuchungsleuchte z. B. durch Einschalten nur der ersten Lichtquellen möglich, ein stark fokussiertes Lichtfeld zu erhalten, während durch Einschalten nur der zweiten Lichtquellen ein größeres weniger fokussiertes Lichtfeld erzeugt werden kann. In einer bevorzugten Ausgestaltung sind auch beliebige Mischungen der von den ersten bzw. zweiten Lichtquellen erzeugten Teil-Lichtfeldern möglich.In a first variant of the present invention, the partial light field generated by the first light sources is more strongly focused than the partial light field generated by the second light sources. So it is with the surgical or examination light according to the invention, for. B. by switching on only the first light sources possible to obtain a strongly focused light field, while by switching on only the second light sources, a larger, less focused light field can be generated. In a preferred embodiment, any desired mixtures of the partial light fields generated by the first or second light sources are also possible.

Dabei ist es einerseits denkbar, daß durch unterschiedliche Anordnung bzw. Ausrichtung von mehreren Lichtquellen deren Einzel-Lichtfelder zu unterschiedlich fokussierten Teil-Lichtfeldern zusammengefügt werden. Andererseits ist es aber auch denkbar, daß bereits die einzelnen Lichtquellen unterschiedliche Einzel-Lichtfelder mit unterschiedlicher Fokussierung aufweisen. Es werden aber sowohl mehrere erste als auch mehrere zweite Lichtquellen verwendet. Vorteilhafterweise werden die unterschiedlichen Teil-Lichtfelder dadurch erreicht, daß sich die Einzel-Lichtfelder der ersten Lichtquellen stärker überlappen als die Einzel-Lichtfelder der zweiten Lichtquellen. Dabei kann die Anordnung so gewählt werden, daß sich die Helligkeitsmaxima der ersten Lichtquellen näher an der optischen Mittelachse der Operations- oder Untersuchungsleuchte befinden als die Helligkeitsmaxima der von den zweiten Lichtquellen erzeugten Einzel-Lichtfelder.On the one hand, it is conceivable that, through different arrangement or alignment of several light sources, their individual light fields are combined to form differently focused partial light fields. On the other hand, however, it is also conceivable that the individual light sources already have different individual light fields with different focussing. However, both a plurality of first and a plurality of second light sources are used. The different partial light fields are advantageously achieved in that the individual light fields of the first light sources overlap more strongly than the individual light fields of the second light sources. The arrangement can be selected so that the brightness maxima of the first light sources are closer to the optical central axis of the operating or examination lamp than the brightness maxima of the individual light fields generated by the second light sources.

Weiterhin vorteilhafterweise weist das erfindungsgemäße optische System keine beweglichen Teile auf. Dies hat die bereits weiter oben erörterten erheblichen Vorteile gegenüber dem Stand der Technik. Weiterhin vorteilhafterweise weist dabei auch das System der Lichtquellen keine beweglichen Teile auf. Insbesondere weisen vorteilhafterweise weder die Lichtquellen, noch das gemeinsame optische System bewegliche Teile auf, so dass sich ein kompaktes und verschleißfreies Leuchtenmodul aus gemeinsamer Optik und Lichtquellen ohne bewegliche Teile ergibt.Furthermore, the optical system according to the invention advantageously has no moving parts. This has the considerable advantages already discussed above over the prior art. Furthermore, the system of light sources also advantageously has no moving parts. In particular, advantageously neither the light sources nor the common optical system have moving parts, so that a compact and wear-free Luminaire module from common optics and light sources without moving parts results.

Vorteilhafterweise sind bei der erfindungsgemäßen Operations- oder Untersuchungsleuchte die Lichtquellen starr ausgerichtet. Eine Verstellbarkeit der Lichtquellen im Stand der Technik ist nicht mehr nötig, da die Fokussierung über die Helligkeit der einzelnen Lichtquellen und damit elektrisch angesteuert werden kann. Hierdurch ergeben sich wiederum die weiter oben beschriebenen Vorteile.The light sources are advantageously rigidly aligned in the surgical or examination light according to the invention. Adjustability of the light sources in the prior art is no longer necessary, since the focusing can be controlled via the brightness of the individual light sources and thus electrically. This in turn results in the advantages described above.

Weiterhin vorteilhafterweise werden die Lichtquellen der erfindungsgemäßen Operations- oder Untersuchungsleuchte von LEDs gebildet. Diese sind wartungsfrei, äußerst langlebig und zudem energiesparend. Gerade da bei der vorliegenden Erfindung vorteilhafterweise eine Vielzahl von Einzel-Lichtquellen zum Einsatz kommt, muß auch die Lichtstärke jeder einzelnen Lichtquelle nicht mehr so hoch sein wie bei Operations- oder Untersuchungsleuchten nach dem Stand der Technik, so daß sich die Verwendung von LEDs besonders anbietet. LEDs erzeugen zudem auch weniger Abwärme, was gerade bei Operations- oder Untersuchungsleuchten von großem Vorteil ist. Auch sind durch LEDs gerade in Kombination mit der erfindungsgemäßen Anordnung ohne bewegliche Elemente sehr platzsparende Konstruktionen möglich. Selbstverständlich können aber auch in der erfindungsgemäßen Leuchte weiterhin andere Lichtquellen wie z. B. Plasmalichtquellen, Halogen- oder Gasentladungslampen eingesetzt werden.Furthermore, the light sources of the surgical or examination light according to the invention are advantageously formed by LEDs. These are maintenance-free, extremely durable and also energy-saving. Precisely because a large number of individual light sources are advantageously used in the present invention, the luminous intensity of each individual light source no longer has to be as high as in operating or examination lights according to the prior art, so that the use of LEDs is particularly useful . LEDs also generate less waste heat, which is a great advantage, especially with operating or examination lights. Very space-saving constructions are also possible through LEDs, especially in combination with the arrangement according to the invention without moving elements. Of course, other light sources such. B. plasma light sources, halogen or gas discharge lamps can be used.

Eine besonders bevorzugte Ausführungsform der erfindungsgemäßen Operations- oder Untersuchungsleuchte umfaßt dabei mindestens zwei Lichtmodule, welche jeweils mindestens eine erste und eine zweite Lichtquelle und vorteilhafterweise ein gemeinsames optisches System aufweisen. Vorteilhafterweise besteht dabei die Operationsleuchte aus einer Vielzahl von solchen Lichtmodulen, da so die bei Operationsleuchten nicht gewünschte Schattenbildung vermeidbar ist. Die Verwendung mehrerer Lichtmodule ermöglicht es, eine ebenso kompakte wie kostengünstige Bauform zu wählen. Dabei teilen sich die jeweils erste und zweite Lichtquelle jedes Lichtmoduls vorteilhafterweise ein gemeinsames optisches System, so daß auch hier eine sehr kostengünstige Lösung gefunden wurde.A particularly preferred embodiment of the surgical or examination light according to the invention comprises at least two light modules which each have at least a first and a second light source and advantageously a common optical system. The surgical light advantageously consists of a large number of such light modules, since in this way the formation of shadows that is not desired in surgical lights can be avoided. The use of several light modules makes it possible to choose a design that is just as compact as it is inexpensive. The first and second light sources of each light module advantageously share a common optical system, so that a very cost-effective solution has also been found here.

Vorteilhafterweise sind dabei die von der ersten und der zweiten Lichtquelle der Lichtmodule erzeugten Lichtkegel in unterschiedliche Richtungen ausgerichtet. Dies geschieht vorteilhafterweise dadurch, daß die erste und die zweite Lichtquelle gegeneinander versetzt hinter dem gemeinsamen optischen System, z. B. einer Linse, angeordnet sind, so daß sich durch die versetzte Anordnung der Lichtquellen hinter dem optischen System automatisch unterschiedliche Ausrichtungen der von den Lichtquellen erzeugten Lichtkegeln ergeben. Durch geschickte Anordnung der unterschiedlichen Lichtmodule kann so z. B. von den ersten Lichtquellen ein fokussiertes Gesamt-Lichtfeld erzeugt werden, während die zweiten Lichtquellen ein größeres Gesamt-Lichtfeld ausleuchten.The light cones generated by the first and the second light source of the light modules are advantageously oriented in different directions. This is advantageously done in that the first and the second light source offset from one another behind the common optical system, for. B. a lens, so that the offset arrangement of the light sources behind the optical system automatically results in different orientations of the light cones generated by the light sources. By cleverly arranging the different light modules, for. B. a focused total light field can be generated by the first light sources, while the second light sources illuminate a larger total light field.

Vorteilhafterweise sind dabei die mindestens zwei Lichtmodule unterschiedlich ausgerichtet. So lassen sich die gewünschten Teil-Lichtfelder erzeugen. Vorteilhafterweise kommen dabei bei der erfindungsgemäßen Operations- oder Untersuchungsleuchte mehrere identisch aufgebaute Lichtmodule zum Einsatz. Dies vermindert die Kosten, da eine Vielzahl von Lichtmodulen hergestellt werden kann, welche dann nebeneinander angeordnet werden.The at least two light modules are advantageously oriented differently. The desired partial light fields can be generated in this way. Advantageously, several identically constructed light modules are used in the surgical or examination light according to the invention. This reduces the costs, since a large number of light modules can be produced, which are then arranged next to one another.

Vorteilhafterweise weisen weiterhin die Lichtmodule keine beweglichen Teile auf, so dass sich eine ebenso kompakte wie verschleißfreie Konstruktion ergibt.Advantageously, the light modules also have no moving parts, so that the result is a construction that is as compact as it is wear-free.

Vorteilhafterweise kommen bei der erfindungsgemäßen Operationsleuchte zur Vermeidung einer Schattenbildung mindestens sechs und noch vorteilhafter acht Lichtquellen bzw. mindestens drei und noch vorteilhafter vier Lichtmodule zum Einsatz. So können einerseits Schatten vermieden werden, andererseits eine Vielzahl von kleinen Lichtquellen verwendet werden, was insbesondere bei einer Verwendung von LEDs von großem Vorteil ist. Die Einzel-Lichtfelder der einzelnen Lichtquellen überlappen sich dabei vorteilhafterweise zumindest teilweise und erzeugen so größere Lichtfelder mit gleichmäßiger Helligkeit.Advantageously, at least six and even more advantageously eight light sources or at least three and even more advantageously four light modules are used in the surgical light according to the invention to avoid shadow formation. In this way, on the one hand, shadows can be avoided and, on the other hand, a large number of small light sources can be used, which is particularly advantageous when using LEDs. The individual light fields of the individual light sources advantageously at least partially overlap and thus generate larger light fields with uniform brightness.

Weiterhin vorteilhafterweise weisen die erfindungsgemäßen Operations- oder Untersuchungsleuchten noch eine dritte Lichtquelle oder zwei oder mehrere dritte Lichtquellen auf, deren Helligkeit getrennt von der der ersten Lichtquelle angesteuert werden kann. So ergibt sich eine noch größere Flexibilität bei der Fokussierung bzw. Verstellung des Gesamt-Lichtfeldes.The surgical or examination lights according to the invention also advantageously have a third light source or two or more third light sources, the brightness of which is controlled separately from that of the first light source can be. This results in even greater flexibility when focusing or adjusting the overall light field.

Vorteilhafterweise erfolgt die Ansteuerung der Helligkeit der Lichtquellen dabei elektrisch oder elektronisch. So können sehr bedienerfreundliche Operations- oder Untersuchungsleuchten ermöglicht werden. Ebenso ist eine geräuschlose, verschleißfreie, wartungsfreie und verzögerungsfreie Ansteuerung der Lichtquellen möglich.The brightness of the light sources is advantageously controlled electrically or electronically. In this way, very user-friendly surgical or examination lights can be made possible. A noiseless, wear-free, maintenance-free and delay-free control of the light sources is also possible.

Bei der ersten Variante kann die Helligkeit der Lichtquellen in mehreren Schritten oder stufenlos eingestellt werden, bevorzugt zwischen 0% und 100% eingestellt werden. Durch eine solche stufenweise oder stufenlose Mischung der von den ersten und zweiten Lichtquellen erzeugten Teil-Lichtfelder ist so auch eine stufenlose Fokussierung und/oder Verstellung des Gesamtlichtfeldes möglich.In the first variant, the brightness of the light sources can be adjusted in several steps or continuously, preferably between 0% and 100%. Such a stepwise or stepless mixing of the partial light fields generated by the first and second light sources also enables stepless focusing and / or adjustment of the overall light field.

Weiterhin werden bei der erfindungsgemäßen Operations- oder Untersuchungsleuchte gemäß der ersten Variante, bei der mehrere erste bzw. zweite Lichtquellen zum Einsatz kommen, die ersten bzw. zweiten Lichtquellen jeweils gemeinsam angesteuert. So ergibt sich eine besonders einfache Ansteuerung, welche dennoch eine beliebige Einstellung der Fokussierung der Leuchte ermöglicht.Furthermore, in the surgical or examination light according to the invention according to the first variant, in which a plurality of first and second light sources are used, the first and second light sources are each controlled jointly. This results in a particularly simple control, which nevertheless allows the focusing of the lamp to be set as desired.

Neben der Fokussierung und damit der Größe des Lichtfeldes kann durch die vorliegende Erfindung auch die Form des Lichtfeldes verändert werden, um sie den spezifischen Bedürfnissen z.B. während einer Operation anzupassen.In addition to the focusing and thus the size of the light field, the present invention can also change the shape of the light field in order to adapt it to specific needs, e.g. during an operation.

Die vorliegende Erfindung umfasst daher in einer zweiten Variante weiterhin eine Operations- oder Untersuchungsleuchte, bei welcher durch unterschiedliche Ansteuerung der Helligkeit der ersten und der zweiten Lichtquellen das von der Operations- oder Untersuchungsleuchte erzeugte Gesamt-Lichtfeld zwischen oval und im wesentlichen rund verstellt wird. Hierdurch kann nicht nur die Fokussierung des Lichtfeldes, sondern auch seine Form durch die unterschiedliche Ansteuerung der einzelnen Lichtquellen beeinflußt werden. Hierdurch kann die erfindungsgemäße Operations- oder Untersuchungsleuchte, ohne dass hierfür bewegliche Teile vorgesehen sein müßten, zwischen einem ovalen und einem im wesentlichen runden Lichtfeld hin und her schalten.The present invention therefore also comprises, in a second variant, an operation or examination lamp in which the total light field generated by the operation or examination lamp is adjusted between oval and essentially round by controlling the brightness of the first and second light sources differently. In this way, not only the focusing of the light field, but also its shape can be influenced by the different control of the individual light sources. As a result, the surgical or examination light according to the invention can be used without moving parts would have to be provided to switch back and forth between an oval and a substantially round light field.

Vorteilhafterweise wird dabei das ovale Gesamt-Lichtfeld durch Überlagerung mindestens zweier Einzel-Lichtfelder erzeugt. Das Einzel-Lichtfeld einer einzelnen Lichtquelle ist dabei üblicherweise im wesentlichen rund, was durch die üblicherweise verwendeten axialsymmetrischen Optiken bedingt ist. Durch die Überlagerung zweier solcher im wesentlichen runder Einzellichtfelder, deren Mittelpunkte gegeneinander versetzt sind, ergibt jedoch auf einfachste Weise ein ovales Gesamtlichtfeld. Selbstverständlich können dabei auch mehr als zwei Lichtquellen eingesetzt werden, um das ovale Gesamtlichtfeld zu erzeugen.The overall oval light field is advantageously generated by superimposing at least two individual light fields. The individual light field of a single light source is usually essentially round, which is due to the axially symmetrical optics that are usually used. By superimposing two such essentially round individual light fields, the centers of which are offset from one another, however, an oval overall light field is produced in the simplest possible way. Of course, more than two light sources can also be used to generate the overall oval light field.

In der zweiten Variante umfasst die erfindungsgemäße Operations- oder Untersuchungsleuchte mindestens zwei erste Lichtquellen, welche gemeinsam ein ovales Lichtfeld erzeugen, und mindestens zwei zweite Lichtquellen, welche ebenfalls gemeinsam ein ovales Lichtfeld erzeugen, wobei das im wesentlichen runde Lichtfeld durch eine Überlagerung der ovalen Lichtfelder erzeugt wird. Hierzu stehen vorteilhafterweise die längeren Durchmesser der beiden ovalen Lichtfelder aufeinander senkrecht. Hierdurch kann durch Einschalten nur der ersten Lichtquellen ein erstes ovales Lichtfeld und durch Einschalten nur der zweiten Lichtquellen ein zweites ovales Lichtfeld, dessen Längsachse auf der Längsachse des ersten Lichtfeldes vorteilhafterweise senkrecht steht, erzeugt werden. Durch gleichzeitiges Einschalten der ersten und der zweiten Lichtquellen ergibt sich dagegen wiederum ein im wesentlichen rundes Lichtfeld. Vorteilhafterweise weisen dabei die beiden ovalen Lichtfelder den gleichen Mittepunkt auf, so dass die beiden ovalen Lichtfelder sowie das im wesentlichen runde Lichtfeld alle in die gleiche Richtung ausgerichtet sind. So kann die Form des Lichtfeldes verteilt werden, ohne dass dessen Ausrichtung verändert würde.In the second variant, the surgical or examination light according to the invention comprises at least two first light sources, which together generate an oval light field, and at least two second light sources, which also together generate an oval light field, the essentially round light field being generated by superimposing the oval light fields becomes. For this purpose, the longer diameters of the two oval light fields are advantageously perpendicular to one another. As a result, a first oval light field can be generated by switching on only the first light sources and a second oval light field, the longitudinal axis of which is advantageously perpendicular to the longitudinal axis of the first light field, can be generated by switching on only the second light sources. By simultaneously switching on the first and the second light sources, on the other hand, an essentially round light field is again produced. The two oval light fields advantageously have the same center point, so that the two oval light fields and the essentially round light field are all aligned in the same direction. In this way, the shape of the light field can be distributed without changing its alignment.

Vorteilhafterweise weist die Operations- oder Untersuchungsleuchte der vorliegenden Erfindung vier auf den Ecken eines Quadrates angeordnete Lichtquellen auf, wobei die zwei ersten und die zwei zweiten Lichtquellen jeweils einander diagonal gegenüberliegen. Hierdurch ergibt sich auf einfache Art und Weise eine Anordnung, mit welcher zwei aufeinander senkrecht stehende ovale Lichtfelder und ein gemeinsames im wesentlichen rundes Gesamtlichtfeld durch die entsprechende Ansteuerung der ersten bzw. der zweiten Lichtquellen bereitgestellt werden kann.The operating or examination light of the present invention advantageously has four light sources arranged on the corners of a square, the two first and the two second light sources each being diagonally opposite one another. This results in an arrangement in a simple manner with which two oval light fields standing perpendicular to one another and a common, substantially round overall light field can be provided by the corresponding control of the first and the second light sources.

Vorteilhafterweise werden dabei bei der zweiten Variante die jeweils ersten bzw. die jeweils zweiten Lichtquellen gemeinsam angesteuert. Hierdurch ergibt sich eine einfache Ansteuerung, durch welche die gewünschten Lichtfelder erzeugt werden können, ohne dass jede der Lichtquellen individuell angesteuert werden müßte. Weiterhin vorteilhafterweise umfasst die vorliegende Erfindung eine Operations- oder Untersuchungsleuchte, bei welcher die Lichtquellen ein Lichtmodul mit einem gemeinsamen optischen System bilden. Z. B. kann es sich dabei um zwei oder mehr LEDs handeln, welche eine gemeinsame Linse und/oder einen gemeinsamen Reflektor aufweisen. Insbesondere können dabei zwei erste und zwei zweite Lichtquellen, welche auf den Ecken eines Rechtecks angeordnet sind, ein gemeinsames optisches System aufweisen.Advantageously, in the second variant, the respective first or the respective second light sources are activated together. This results in a simple control by means of which the desired light fields can be generated without each of the light sources having to be controlled individually. The present invention also advantageously comprises a surgical or examination lamp in which the light sources form a light module with a common optical system. For example, it can be two or more LEDs which have a common lens and / or a common reflector. In particular, two first and two second light sources, which are arranged on the corners of a rectangle, can have a common optical system.

Weiterhin vorteilhafterweise sind dabei die Lichtquellen auf einer gemeinsamen Platine angeordnet. Auch hierdurch ergibt sich eine einfach herzustellende und kompakte Anordnung eines Lichtmoduls.Furthermore, the light sources are advantageously arranged on a common circuit board. This also results in a compact and easy-to-manufacture arrangement of a light module.

Weiterhin vorteilhafterweise umfasst die Operations- oder Untersuchungsleuchte der vorliegenden Erfindung dabei mindestens zwei erste und/oder mindestens zwei zweite Lichtquellen, wobei die zwei ersten und/oder die zwei zweiten Lichtquellen den gleichen Abstand zur optischen Achse des gemeinsamen optischen Systems aufweisen. Hierdurch ergibt sich, wenn die zwei ersten und/oder zwei zweiten Lichtquellen ein gemeinsames Lichtfeld erzeugen, eine symmetrische Anordnung des Lichtfeldes um die optische Achse des gemeinsamen optischen Systems.The operating or examination light of the present invention furthermore advantageously comprises at least two first and / or at least two second light sources, the two first and / or the two second light sources being at the same distance from the optical axis of the common optical system. If the two first and / or two second light sources generate a common light field, this results in a symmetrical arrangement of the light field around the optical axis of the common optical system.

Weiterhin vorteilhafterweise weisen erfindungsgemäß die mindestens eine und die mindestens eine zweite Lichtquelle den gleichen Abstand zur optischen Achse des gemeinsamen optischen Systems auf. Hierdurch sind die von den ersten und zweiten Lichtquellen erzeugten Einzellichtfelder relativ zur optischen Achse identisch ausgerichtet. Werden z. b. durch zwei erste und zwei zweite Lichtquellen jeweils ovale Lichtfelder erzeugt, weisen diese hierdurch gegenüber der optischen Achse die gleiche Ausrichtung und die gleiche Ausdehnung auf. Hierdurch lässt sich ein gleichmäßiges Gesamtlichtfeld der ersten und der zweiten Lichtquellen erreichen.According to the invention, the at least one and the at least one second light source are also advantageously at the same distance from the optical axis of the common optical system. As a result, the individual light fields generated by the first and second light sources are aligned identically relative to the optical axis. Are for example by two first and two second light sources Generated oval light fields in each case, these have the same orientation and the same extent with respect to the optical axis. This makes it possible to achieve a uniform overall light field of the first and the second light sources.

Selbstverständlich ergeben sich die erfindungsgemäßen Vorteile nicht nur bei Operations- oder Untersuchungsleuchten, sonder bei jeder Leuchte, deren Fokussierung oder Lichtfeld verstellbar sein soll. Die vorliegende Erfindung umfaßt deshalb weiterhin eine Leuchte mit einem oder mehreren der oben beschriebenen Merkmale.Of course, the advantages according to the invention result not only in surgical or examination lights, but also in every light whose focus or light field should be adjustable. The present invention therefore further comprises a luminaire having one or more of the features described above.

Ein Ausführungsbeispiel der vorliegenden Erfindung wird nun anhand von Zeichnungen näher beschrieben.An embodiment of the present invention will now be described in more detail with reference to drawings.

Figuren 1 a und 1 b zeigen ein erstes Ausführungsbeispiel eines erfindungsgemäßen Lichtmoduls (30), welches eine erste Lichtquelle (1) sowie eine zweite Lichtquelle (2) aufweist. Diese sind nebeneinander versetzt auf einer Grundplatte angeordnet und verfügen über eine gemeinsame Optik (3). Diese besteht z. B. aus einer Linse oder einer Linsenkombination. Figures 1 a and 1b show a first embodiment of a light module (30) according to the invention, which has a first light source (1) and a second light source (2). These are arranged offset next to one another on a base plate and have a common optic (3). This consists z. B. from a lens or a combination of lenses.

In Figur 1 a ist nun der Strahlengang der ersten Lichtquelle (1) dargestellt. Dieser erzeugt ein Einzel-Lichtfeld (11) der ersten Lichtquelle (1), dessen Maximum (21) nach links gegen die optische Mittelachse (10) der Optik (3) bzw. der Lichteinheit (30) verschoben ist. In Figur 1b ist dagegen der Strahlengang der zweiten Lichtquelle (2) gezeigt, welche ein Lichtfeld (12) erzeugt, dessen Maximum (22) nach rechts gegen die optische Mittelachse (10) verschoben ist. Hierdurch erzeugen also die erste Lichtquelle (1) und die zweite Lichtquelle (2) Einzel-Lichtfelder (11) und (12), deren Helligkeitsmaxima gegeneinander verschoben sind. Ebenso sind diese beiden Einzel-Lichtfelder (11) und (12) in unterschiedliche Richtungen ausgerichtet.In Figure 1 a the beam path of the first light source (1) is now shown. This generates a single light field (11) of the first light source (1), the maximum (21) of which is shifted to the left against the optical central axis (10) of the optics (3) or the light unit (30). In Figure 1b on the other hand, the beam path of the second light source (2) is shown, which generates a light field (12) whose maximum (22) is shifted to the right relative to the optical central axis (10). In this way, the first light source (1) and the second light source (2) generate individual light fields (11) and (12), the brightness maxima of which are shifted relative to one another. These two individual light fields (11) and (12) are also aligned in different directions.

Wie aus den Figuren 2a und 2b hervorgeht, die im Wesentlichen die gleich Situation wie die Figuren 1 a und 1 b darstellen, ist dabei der Lichtkegel der ersten Lichtquelle (1), welcher ein Lichtfeld (11) hervorruft, gegen die Mittelachse (10) nach links verschoben, während der Lichtkegel der zweiten Lichtquelle (2), welcher ein Lichtfeld (12) hervorruft, nach rechts verschoben ist. Durch die unterschiedliche Ansteuerung der ersten Lichtquelle (1) und der zweiten Lichtquelle (2) können so unterschiedliche Lichtfelder erzeugt werden.As from the Figures 2a and 2b showing which is essentially the same situation as that Figures 1 a and 1 b, the light cone of the first light source (1), which creates a light field (11), is shifted to the left against the central axis (10), while the light cone of the second light source (2), which creates a light field (12 ) is shifted to the right. As a result of the different control of the first light source (1) and the second light source (2), different light fields can be generated.

Figur 3 zeigt das erste Ausführungsbeispiel des Lichtmoduls (30) nochmals in einer Schnittansicht durch die Linie A-A in Figur 1 a. Hierbei sind wieder die erste Lichtquelle (1) und die danebenliegenden zweite Lichtquelle (2) zu sehen, sowie die davor angeordnete gemeinsame Optik (3). Die Lichtquellen (1) und (2) sind dabei LEDs, welche bei der vorliegenden Erfindung vorteilhafterweise zum Einsatz kommen. Diese LEDs strahlen dabei beide weißes Licht ab und sind identisch aufgebaut. Figure 3 shows the first embodiment of the light module (30) again in a sectional view through the line AA in Figure 1 a. Here again the first light source (1) and the second light source (2) lying next to it can be seen, as well as the common optics (3) arranged in front of it. The light sources (1) and (2) are LEDs, which are advantageously used in the present invention. These LEDs both emit white light and are constructed identically.

In Figuren 4a und 4b ist nun die erfindungsgemäße Operations- oder Untersuchungsleuchte gezeigt, welche aus mehreren Lichtmodulen (30, 31, 32 und 33), wie sie in Figuren 1 bis 3 gezeigt wurden, aufgebaut ist. Dabei kommen im Wesentlichen identische Lichtmodule zum Einsatz, deren optische Ausrichtung jedoch gegeneinander gedreht ist. Die einzelnen Lichtquellen der Lichteinheiten sind dazu unterschiedlich angeordnet, so daß auch die einzelnen Lichtfelder (11) der ersten Lichtquellen (1) bzw. die Lichtfelder (12) der zweiten Lichtquellen (2) von Lichtmodul zu Lichtmodul unterschiedlich ausgerichtet sind. Die einzelnen Lichtfelder (11) bzw. (12) der mehreren Lichtmodule überdecken sich so zu einem Teil-Lichtfeld (41) bzw. (42).In Figures 4a and 4b is now the inventive surgical or Examination light shown, which consists of several light modules (30, 31, 32 and 33), as shown in Figures 1 to 3 has been shown. Essentially identical light modules are used, but their optical alignment is rotated relative to one another. The individual light sources of the light units are arranged differently so that the individual light fields (11) of the first light sources (1) or the light fields (12) of the second light sources (2) are aligned differently from light module to light module. The individual light fields (11) or (12) of the multiple light modules thus overlap to form a partial light field (41) or (42).

Wie in Figur 4a dargestellt, erzeugt die teilweise Überlagerung der von den ersten Lichtquellen (1) erzeugten Einzel-Lichtfelder (11) ein Teil-Lichtfeld (41), welches stark fokussiert ist, Dies wird dadurch erreicht, daß der Überlagerungsbereich, in welchem sich die einzelnen Einzel-Lichtfelder (11) überlagern, relativ groß ist, so daß die Größe des Teil-Lichtfeldes (41) nicht erheblich größer ist als die der Einzel-Lichtfelder (11). Hierdurch ergibt sich ein stark fokussierter sehr heller und kleiner Lichtfleck.As in Figure 4a shown, the partial superimposition of the individual light fields (11) generated by the first light sources (1) generates a partial light field (41) which is strongly focused. This is achieved in that the superimposition area in which the individual individual Overlay light fields (11) is relatively large, so that the size of the partial light field (41) is not significantly larger than that of the individual light fields (11). This results in a strongly focused, very bright and small light spot.

In Figur 4b ist dagegen das von den zweiten Lichtquellen (2) erzeugte Teil-Lichtfeld (42) gezeigt. Hierbei überlagern sich die von den zweiten Lichtquellen (2) erzeugten Einzel-Lichtfelder (12) nur wenig, so daß sich ein großflächiges und dafür weniger helles Teil-Lichtfeld (42) ergibt.In Figure 4b on the other hand, the partial light field (42) generated by the second light sources (2) is shown. The individual light fields (12) generated by the second light sources (2) overlap only slightly, so that a large-area and therefore less bright partial light field (42) results.

Wie aus einem Vergleich der Figuren 4a und 4b hervorgeht, werden die unterschiedlichen Teil-Lichtfelder (41) und (42) dadurch erreicht, daß sich die Einzel-Lichtfelder der ersten Lichtquellen (1) stärker überlappen als die Einzel-Lichtfelder (12) der zweiten Lichtquellen (2). Dabei ist die Anordnung so gewählt, daß sich die Helligkeitsmaxima der ersten Lichtquellen (1) näher an der optischen Mittelachse der Operations- oder Untersuchungsleuchte befinden als die Helligkeitsmaxima der von den zweiten Lichtquellen (2) erzeugten Einzel-Lichtfelder (12).As from a comparison of the Figures 4a and 4b As can be seen, the different partial light fields (41) and (42) are achieved in that the individual light fields of the first light sources (1) overlap more strongly than the individual light fields (12) of the second light sources (2). The arrangement is chosen so that the brightness maxima of the first light sources (1) are closer to the optical central axis of the operating or examination lamp than the brightness maxima of the individual light fields (12) generated by the second light sources (2).

Durch die nicht gezeigte Ansteuerungseinheit der Operations- oder Untersuchungsleuchte lassen sich die ersten und die zweiten Lichtquellen jeweils getrennt ansteuern. So ist es möglich, durch jeweils unterschiedliche Ansteuerung der Helligkeit der ersten und der zweiten Lichtquellen eine Verstellung bzw. eine unterschiedliche Fokussierung des von der Operations- oder Untersuchungsleuchte erzeugten Gesamt-Lichtfeldes zu bewirken, welches durch die Überlagerung der Teil-Lichtfelder (41) oder (42) gebildet wird.The first and second light sources can each be controlled separately by the control unit, not shown, of the surgical or examination light. So it is possible through different controls the brightness of the first and second light sources to adjust or differently focus the total light field generated by the surgical or examination lamp, which is formed by the superposition of the partial light fields (41) or (42).

Werden so z. B. nur die ersten Lichtquellen (1) angesteuert, ergibt sich ein maximal fokussiertes Lichtfeld. Werden dagegen nur die zweiten Lichtquellen (2) angesteuert ergibt sich ein minimal fokussiertes Lichtfeld mit der größten Ausdehnung. Zwischen diesen beiden Grenzstellungen gibt es beliebige Zwischeneinstellungen, in denen sowohl die ersten als auch die zweiten Lichtquellen jeweils von 0-100% ihrer Helligkeit angesteuert werden können. Hierdurch läßt sich eine stufenlose Einstellung der Fokussierung der erfindungsgemäßen Operations- oder Untersuchungsleuchte erreichen.Will z. B. only the first light sources (1) controlled, the result is a maximally focused light field. If, on the other hand, only the second light sources (2) are controlled, a minimally focused light field with the greatest expansion results. Between these two limit positions there are any intermediate settings in which both the first and the second light sources can each be controlled from 0-100% of their brightness. In this way, a stepless adjustment of the focus of the surgical or examination light according to the invention can be achieved.

Hierbei kann komplett auf bewegliche Teile verzichtet werden, da diese Fokussierung einfach durch die unterschiedliche Ansteuerung der Helligkeit der einzelnen Lichtquellen ermöglicht wird. Auch die einzelnen Lichtquellen sind starr gegeneinander ausgerichtet, eine Verschiebbarkeit ist hier nicht mehr nötig.Moving parts can be completely dispensed with, as this focusing is made possible simply by the different control of the brightness of the individual light sources. The individual light sources are also rigidly aligned with one another, so that they can no longer be moved.

Bei dem vorliegenden Ausführungsbeispiel der erfindungsgemäßen Operations- oder Untersuchungsleuchte sind die erste und die zweite Lichtquelle jeweils in einem Lichtmodul integriert und weisen eine gemeinsame Optik auf. Dies ermöglicht eine ebenso kostengünstige wie platzsparende Konstruktion. Dabei kann eine Vielzahl von gleichartigen Lichtmodulen nebeneinander gesetzt werden, wobei lediglich die Anordnung der ersten und der zweiten Lichtquelle von Modul zu Modul gegeneinander gedreht wird, um so auch die Lichtkegel der einzelnen Lichtquellen in unterschiedliche Richtungen auszurichten. Dabei sind auch noch erheblich mehr einzelne Lichtmodule bzw. Lichtquellen als im Ausführungsbeispiel möglich. So können für die Einzel-Lichtquelle relativ lichtschwache Lichtquellen verwendet werden, wobei zudem die Gleichmäßigkeit der von der Überlagerung der Einzel-Lichtfelder gebildeten Teil- bzw. Gesamt-Lichtfelder verbessert und die Schattenbildung vermindert werden.In the present exemplary embodiment of the surgical or examination light according to the invention, the first and the second light source are each integrated in a light module and have a common optical system. This enables a construction that is as economical as it is space-saving. A large number of similar light modules can be placed next to one another, with only the arrangement of the first and the second light source being rotated from module to module in order to align the light cones of the individual light sources in different directions. In this case, considerably more individual light modules or light sources are possible than in the exemplary embodiment. Thus, relatively weak light sources can be used for the individual light source, the uniformity of the partial or total light fields formed by the superimposition of the individual light fields being improved and the formation of shadows being reduced.

In Figur 5 ist weiterhin dargestellt, wie sich aus der Überlagerung der Einzel-Lichtfelder der ersten und zweiten Lichtquelle eines Lichtmoduls gemäß dem ersten Ausführungsbeispiel, wie es in Figuren 1 bis 3 beschrieben wurde, ein ovales Gesamtlichtfeld ergibt. Das Lichtmodul weist eine erste Lichtquelle L1 und eine zweite Lichtquelle L2 auf, welche nebeneinander auf einer Platine angeordnet sind und über eine gemeinsame Optik 3, in diesem Fall eine gemeinsame Linse, verfügen. Die beiden Lichtquellen L1 und L2 weisen dabei den gleichen Abstand zur optischen Achse 10 des optischen Systems 3 auf. Die Lichtfelder aus der Lichtquelle L1 und der Lichtquelle L2 weisen, wie dargestellt, eine im wesentlichen runde Form auf, welche durch den Abstand der Lichtquellen von der optischen Achse des optischen Systems lediglich ganz leicht ins ovale verzerrt ist. Die Überlagerung der beiden Lichtfelder ergibt dagegen ein deutlich ovales Lichtfeld, so dass durch das gleichzeitige Anschalten der ersten und der zweiten Lichtquelle ein ovales Lichtfeld, durch einzelnes Anschalten der ersten oder der zweiten Lichtquelle dagegen ein im wesentlichen rundes Lichtfeld erzeugt werden kann. Allerdings weisen die im wesentlichen runden Lichtfelder und das ovale Gesamt-Lichtfeld jeweils unterschiedliche Ausrichtungen auf.In Figure 5 is also shown how the superimposition of the individual light fields the first and second light source of a light module according to the first embodiment, as shown in FIG Figures 1 to 3 has been described, results in an oval overall light field. The light module has a first light source L1 and a second light source L2, which are arranged next to one another on a circuit board and have a common optical system 3, in this case a common lens. The two light sources L1 and L2 are at the same distance from the optical axis 10 of the optical system 3. The light fields from the light source L1 and the light source L2 have, as shown, an essentially round shape which is only slightly distorted into an oval due to the distance between the light sources and the optical axis of the optical system. The superimposition of the two light fields, on the other hand, results in a clearly oval light field, so that an oval light field can be generated by simultaneously switching on the first and second light source, whereas an essentially round light field can be produced by switching on the first or second light source individually. However, the essentially round light fields and the overall oval light field each have different orientations.

In Figur 6 ist nun ein zweites Ausführungsbeispiel gemäß der vorliegenden Erfindung gezeigt, bei welchem ebenfalls durch eine unterschiedliche Ansteuerung der Helligkeit der ersten und der zweiten Lichtquellen ein ovales bzw. im wesentlichen rundes Gesamtlichtfeld erzeugt werden kann. Das erfindungsgemäße Lichtmodul weist dabei zwei erste Lichtquellen L1 und L3 und zwei zweite Lichtquellen L2 und L4 auf, welche mit einem gemeinsamen optischen System 3, z. B. mit einer Linse oder einem Reflektor, ausgestattet sind. Dabei erzeugen die beiden ersten Lichtquellen L1 und L3 gemeinsam ein ovales Lichtfeld, dessen längerer Durchmesser 61 in Figur 6 von links unten nach rechts oben verläuft. Die zweiten Lichtquellen L2 und L4 erzeugen ebenfalls gemeinsam ein ovales Lichtfeld, dessen längerer Durchmesser 62 in Figur 6 von links oben nach rechts unten verläuft. Die längeren Durchmesser der jeweils von den ersten bzw. zweiten Lichtquellen erzeugten Lichtfelder stehen damit senkrecht aufeinander. Werden dagegen sowohl die ersten als auch die zweiten Lichtquellen angeschaltet, ergibt sich ein im wesentlichen rundes Lichtfeld, das sich aus der Überlagerung der Einzellichtfelder aller Lichtquellen ergibt.In Figure 6 a second embodiment according to the present invention is now shown, in which an oval or essentially round overall light field can also be generated by a different control of the brightness of the first and second light sources. The light module according to the invention has two first light sources L1 and L3 and two second light sources L2 and L4, which are connected to a common optical system 3, e.g. B. are equipped with a lens or a reflector. The two first light sources L1 and L3 jointly generate an oval light field, the longer diameter of which is 61 in Figure 6 runs from bottom left to top right. The second light sources L2 and L4 also jointly generate an oval light field whose longer diameter 62 in Figure 6 runs from top left to bottom right. The longer diameters of the light fields generated by the first and second light sources are thus perpendicular to one another. If, on the other hand, both the first and the second light sources are switched on, an essentially round light field results, which results from the superposition of the individual light fields of all light sources.

Benötigt z. B. der Operateur ein ovales Lichtfeld, um einen ovalen bereich auszuleuchten, kann er durch Anschalten entweder der ersten Lichtquellen L1 und L3 oder der zweiten Lichtquellen L2 und L4 ovale Lichtfelder mit zueinander um 90 Grad verschobener Ausrichtung erzeugen und so die Form und Ausrichtung des Lichtfeldes dem auszuleuchtenden Bereich optimal anpassen. Wird dagegen ein rundes Lichtfeld benötigt, so werden sowohl die ersten als auch die zweiten Lichtquellen angeschaltet.Requires z. For example, the surgeon can use an oval light field to illuminate an oval area by switching on either the first light sources L1 and L3 or the second light sources L2 and L4 to create oval light fields with an alignment shifted by 90 degrees and thus the shape and alignment of the light field optimally adapt to the area to be illuminated. If, on the other hand, a round light field is required, both the first and the second light sources are switched on.

Erfindungsgemäß sind die vier Lichtquellen auf den Ecken eines Quadrates angeordnet, wobei die zwei ersten und die zwei zweiten Lichtquellen jeweils einander diagonal gegenüberliegen. Die Lichtquellen sind weiterhin auf einer gemeinsamen Platine angeordnet und weisen eine gemeinsame Optik auf, so dass sich ein äußerst kompaktes System ergibt.According to the invention, the four light sources are arranged on the corners of a square, the two first and the two second light sources each being diagonally opposite one another. The light sources are also arranged on a common circuit board and have a common optical system, so that an extremely compact system results.

Durch diese Anordnung wird ebenfalls sichergestellt, dass die zwei ersten und die zwei zweiten Lichtquellen jeweils den gleichen Abstand zur optischen Achse des gemeinsamen optischen Systems aufweisen, so dass die jeweils von den ersten bzw. zweiten Lichtquellen erzeugten ovalen Lichtfelder eine Mittelachse aufweisen, welche mit der Mittelachse des gemeinsamen optischen Systems zusammenfällt. Zudem weisen auch die ersten und die zweiten Lichtquellen jeweils den gleichen Abstand zur optischen Achse des gemeinsamen optischen Systems auf, so dass die jeweils erzeugten ovalen Lichtfelder bis auf eine Drehung des längeren Durchmessers um 90° identische Lichtfelder aufweisen. Hierdurch ergibt sich durch die Überlagerung der beiden ovalen Lichtfelder ein besonders gleichmäßiges, im wesentlichen rundes Lichtfeld.This arrangement also ensures that the two first and the two second light sources each have the same distance from the optical axis of the common optical system, so that the oval light fields generated by the first and second light sources each have a central axis that coincides with the Central axis of the common optical system coincides. In addition, the first and the second light sources are each at the same distance from the optical axis of the common optical system, so that the oval light fields generated in each case have identical light fields except for a 90 ° rotation of the longer diameter. As a result, the superposition of the two oval light fields results in a particularly uniform, essentially round light field.

Bei den Lichtquellen L1 bis L4 handelt es sich auch im zweiten Ausführungsbeispiel um LEDs, welche für diesen Einsatz optimal geeignet sind, da sie eine kompakte und wartungsfreie Leuchte ergeben, welche nur wenig Wärme abstrahlt.The light sources L1 to L4 are also LEDs in the second exemplary embodiment, which are ideally suited for this application, since they result in a compact and maintenance-free lamp which emits only little heat.

Weiterhin ist es erfindungsgemäß möglich, noch weitere Lichtquellen in ein Lichtmodul, wie es in Figur 6 gezeigt ist, zu integrieren, um so die Form der einzelnen Lichtfelder, welche durch das Lichtmodul erzeugt werden können, weiter zu beeinflussen und/oder die Helligkeit des Lichtmoduls zu erhöhen.It is also possible according to the invention to incorporate further light sources in a light module, as shown in FIG Figure 6 is shown to integrate so as to shape the to further influence individual light fields which can be generated by the light module and / or to increase the brightness of the light module.

Ebenso ist es möglich, mehrere Lichtmodule, wie sie in Figur 6 gezeigt sind, in einer erfindungsgemäßen Operations- oder Untersuchungsleuchte gemeinsam zu integrieren, um so eine höhere Lichtleistung und eine höhere Flexibilität bei der Gestaltung der Form des Lichtfeldes zu haben.It is also possible to use several light modules, as shown in Figure 6 are shown to be integrated together in a surgical or examination light according to the invention, in order to have a higher light output and greater flexibility in the design of the shape of the light field.
