Abstract

The light (1) has light modules (2a-2e) that are assembled together to form a light source. Three light zones are arranged concentric to each other and are separated from each other. The zones are controllable with respect to their light intensities. Units are provided for switching-off and dimming illuminants of the light zones, where the illuminants are formed using LEDs. A controller is provided for controlling the intensities of the illuminants in individual ranges. Different intensities of the illuminants are stored in the controller.

Description

Die Erfindung betrifft eine Operationsleuchte zur Erzeugung eines Leuchtfeldes.The invention relates to a surgical lamp for generating a light field.

Bei Operationen ergeben sich unterschiedliche Beleuchtungssituationen. Operateure unterbrechen den Strahlengang des Lichts der Operationsleuchte. Tiefe, enge und großflächige Wunden müssen unterschiedlich ausgeleuchtet werden.In operations, different lighting situations arise. Operators interrupt the beam path of the light of the operating light. Deep, narrow and large wounds have to be illuminated differently.

Aufgrund der stark unterschiedlichen Beleuchtungssituationen ist dies mit einer Leuchte mit fester Lichtverteilung nicht erreichbar.Due to the very different lighting situations, this is not achievable with a luminaire with fixed light distribution.

Der Anmelder hat sich die Aufgabe gestellt, bei unterschiedlichen Beleuchtungssituationen mit einer einzigen Operationsleuchte arbeiten zu können.The Applicant has set itself the task of being able to work in different lighting situations with a single operating light.

Diese Aufgabe wird durch eine Operationsleuchte gelöst, bei der mindestens drei konzentrisch zu einander angeordnete Leuchtzonen vorgesehen sind, welche getrennt voneinander bezüglich ihrer Lichtintensität ansteuerbar sind.This object is achieved by a surgical light in which at least three concentrically arranged lighting zones are provided, which can be controlled separately from one another with respect to their light intensity.

Dokument US 2003/0185009 A1 zeigt eine Operationleuchte mit variablen Lichtintestität. Dokument DE 100 64 544 A1 offenbart eine Zahnarleuchte die drei konzentrisch zueinander angeordnete Leuchtzohnen aufweist die bezüglich ihrer Lichtintensität ansteuebar sind.document US 2003/0185009 A1 shows an operation light with variable Lichtintestität. document DE 100 64 544 A1 discloses a dental lamp which has three concentrically arranged light tufts which are controllable with respect to their light intensity.

Mithilfe der Erfindung ist folgende Arbeitsweise möglich:

  • ■ Zonenweises Ein-/Ausschalten und Dimmen der Lichtaustrittfläche.
  • ■ Intensitätsregelung (Dimmung) der leuchtenden Fläche.
  • ■ Konstante Beleuchtungsstärke in allen Schaltzuständen.
With the aid of the invention, the following procedure is possible:
  • ■ Zone-on / off switching and dimming of the light exit surface.
  • ■ Intensity control (dimming) of the illuminated area.
  • ■ Constant illuminance in all switching states.

Die Ansteuerung der Leuchtzonen kann auf technisch einfache Weise durch Mittel zum Ausschalten und Dimmen ausgebildet sein.The control of the lighting zones can be designed in a technically simple manner by switching off and dimming.

Eine günstige Möglichkeit, die Lithtaustrittsfläche in verschiedene schaltbare Leuchtzonen I, II, III aufzuteilen ist die Verwendung einer Vielzahl von LEDs in Kombination mit Linsen, die gleichmäßig über die Lichtaustrittsfläche verteilt sind.A convenient way to divide the Lithtaustrittsfläche in different switchable light zones I, II, III is the use of a variety of LEDs in combination with lenses that are evenly distributed over the light exit surface.

Zur Einstellung und Anpassung der Operationsleuchte an unterschiedliche Situationen ist es vorteilhaft, dass verschiedene Intensitäten der Leuchtmittel in der Steuerung der Leuchtzonen gespeichert werdenFor adjusting and adapting the operating light to different situations, it is advantageous that different intensities of the lighting means are stored in the control of the lighting zones

Die einzelnen Leuchtzonen können dabei variabel zueinander ein- bzw. ausgeschaltet werden. Zusätzlich sind verschiedene Dimmzustände einstellbar. Das Leuchtfeld bleibt in allen Schaltzuständen von der Größe unverändert. Zur Erzielung der konstanten Beleuchtungsstärke Ec ist es notwendig, die Lichtintensität der jeweils eingeschalteten Leuchtzonen im Bereich von 100 bis 250 % der Ausgangsbeleuchtungsstarke (alle Leuchtzonen eingeschaltet) zu variieren.The individual lighting zones can be switched on or off variably with each other. In addition, various dimming states can be set. The light field remains unchanged in all switching states of the size. In order to obtain the constant illuminance E c , it is necessary to vary the light intensity of the respectively activated luminous zones in the range of 100 to 250% of the output illuminance (all luminous zones switched on).

Figur 1 zeigt, dass als Lichtquelle einer Operationsleuchte 1 einzelne Lichtmodule 2a bis 2e nahezu randlos aneinander gefügt sind. Randios bedeutet im Sinne der Erfindung, dass die Übergänge zwischen den einzelnen Lichtmodulen 2a bis 2e keinen wesentlichen Einfluss auf die optischen Eigenschaften, insbesondere auf den Lichtaustritt in Richtung der Operationsstelle, besitzen. Das erzeugte Licht wird trotz der aus mehreren Lichtmodulen 2a bis 2e zusammengesetzten Lichtquelle als einheitlich wahrgenommen. Jedes Lichtmodul 2a bis 2e umfasst wiederum eine Vielzahl einzelner LEDs, beispielsweise 30 bis 50. Hieraus ergeben sich lichttechnische Vorteile analog zu Großspiegelleuchten wie eine theoretisch optimale Schattenfreiheit durch großflächigen Lichtaustritt. Jede LED-LinsenAnordnung kann die komplette Operationsstelle ausleuchten. Beim Betrieb eines beispielsweise halben Moduls bleibt deshalb die Feldgröße unverändert. Daher kann auch jedes Lichtmodul 2a bis 2e selbst eine komplette Operationsstelle ausleuchten. FIG. 1 shows that as the light source of an operating light 1, individual light modules 2a to 2e are joined to one another almost without borders. Randios means in the sense of the invention that the transitions between the individual light modules 2a to 2e have no significant influence on the optical properties, in particular on the light emission in the direction of the surgical site. The generated light is in spite of the multiple light modules 2a to 2e composite light source perceived as uniform. Each light module 2a to 2e in turn comprises a plurality of individual LEDs, for example 30 to 50. This results in photometric advantages similar to large mirror lights such as a theoretically optimal freedom from shadow by large-scale light emission. Each LED lens assembly can illuminate the entire surgical site. When operating an example half module, therefore, the field size remains unchanged. Therefore, each light module 2a to 2e itself can illuminate a complete surgical site.

Durch eine umschaltbare Lichtverteilung über die Lichtaustrittsfläche der Operationsleuchte bei gleichzeitig konstanter Beleuchtungsstärke Ec können mit einem einzigen Leuchtenkörper Operationsleuchten mit unterschiedlicher Charakteristik dargestellt werden:By a switchable light distribution over the light exit surface of the surgical light with a constant illuminance E c can be represented with a single lamp body surgical lights with different characteristics:

In der OP-Leuchtennorm EN 60601-2-41 werden exemplarisch 6 unterschiedliche Beleuchtungssituationen angeführt, welche den realen OP-Verlauf widerspiegeln. Tiefe enge Wundkanäle simuliert hierbei ein definierter Tubus und Hindernisse wie Köpfe werden durch Scheiben (sog. Schatter) im Strahlengang wiedergegeben. Ferner existieren Kombinationen aus Schattern und Tubus.In the surgical lighting standard EN 60601-2-41, 6 different lighting situations are given by way of example, which reflect the real course of the surgery. Deep narrow wound channels simulate a defined tube and obstacles like heads get through Slices (so-called Schatter) reproduced in the beam path. Furthermore, there are combinations of shattern and tube.

Die unterschiedlichen Beleuchtungssituationen können durch unterschiedliches Ansteuern der 3 Leuchtzonen I, II, III (siehe Figuren 2b bis 6b) optimal beleuchtet werden. Eine entsprechende Steuerung erlaubt das direkte Abrufen der jeweiligen Schaltzustände. Die jeweils aufgerufenen Schaltzustände sind ohne Änderung Lichtaustrittscharakteristik zusätzlich in der Intensität dimmbar.The different lighting situations can be optimally illuminated by different activation of the 3 lighting zones I, II, III (see FIGS. 2b to 6b). A corresponding control allows direct retrieval of the respective switching states. The respectively called switching states are additionally dimmable in intensity without changing the light output characteristic.

Für tiefe und enge Wunden, wie durch den Tubus 3 gemäß Figur 2a angedeutet, wird das gesamte Licht überwiegend aus der Mitte des Leuchtenkörpers abgegeben und gelangt damit vollständig in den Wundkanal. Die Leuchtzone III ist im Gegensatz zu I, II nahezu komplett deaktiviert, wie die Sicht auf die Lichtaustrittsfläche gemäß Figur 2b zeigt. Schwarz markierte LEDs sind nicht aktiviert.For deep and narrow wounds, as indicated by the tube 3 according to FIG. 2a , the entire light is emitted predominantly from the center of the lamp body and thus reaches completely into the wound canal. The luminous zone III is almost completely deactivated in contrast to I, II, as the view of the light exit surface according to FIG. 2b shows. Black marked LEDs are not activated.

Beim Arbeiten eines Operateurs im Zentrum unter der Operationsleuchte 1, wie durch den Schatter 4 gemäß Figur 3a angedeutet, wird das gesamte Licht überwiegend aus der Mitte des Leuchtenkörpers (Leuchtzone I) deaktiviert. Das gesamte Licht wird durch die Leuchtzonen II, III erzeugt. Die Leuchtzone I ist im Gegensatz zu II, III nahezu komplett deaktiviert, wie die Sicht auf die Lichtaustrittsfläche gemäß Figur 3b zeigt. Schwarz markierte LEDs sind nicht aktiviert.When operating an operator in the center under the operating light 1, as indicated by the Schatter 4 according to Figure 3a , the entire light is predominantly from the center of the Luminaire body (light zone I) deactivated. All the light is generated by the light zones II, III. The luminous zone I is almost completely deactivated in contrast to II, III, as the view of the light exit surface according to FIG. 3b shows. Black marked LEDs are not activated.

Beim Arbeiten eines Operateurs unter der Operationsleuchte 1 direkt über einer tiefen Wunde, wie durch den Tubus 3 und den Schatter 4 gemäß Figur 4a angedeutet, wird nahezu das gesamte Licht überwiegend aus der Mitte des Leuchtenkörpers (Leuchtzone I) und aus der Leuchtzone III deaktiviert. Das gesamte Licht wird durch die Leuchtzone II erzeugt. Die Leuchtzonen I, III sind im Gegensatz zu II nahezu komplett deaktiviert, wie die Sicht auf die Lichtaustrittsfläche gemäß Figur 4b zeigt. Schwarz markierte LEDs sind nicht aktiviert.When operating an operator under the operating light 1 directly over a deep wound, as indicated by the tube 3 and the shading 4 according to Figure 4a , almost all the light is deactivated mainly from the center of the lamp body (light zone I) and from the light zone III. All light is generated by the luminous zone II. The luminous zones I, III are almost completely deactivated in contrast to II, as the view of the light exit surface according to FIG. 4b shows. Black marked LEDs are not activated.

Bei großflächigen Wunden leuchtet dagegen die gesamte Lichtaustrittsfläche gemäß Figur 5b, wenn zwei Operateure (siehe Schatter 4 gemäß Figur 5a) über den Wunden arbeiten.In the case of large-area wounds, on the other hand, the entire light-emitting surface according to FIG. 5b shines when two surgeons (see shader 4 according to FIG. 5a) work over the wounds.

Beim Arbeiten zweier Operateure (Schatter 4 gemäß Figur 6a) unter der Operationsleuchte 1 seitlich zu einer tiefen Wunde, wie durch den Tubus 3 angedeutet, wird nahezu das gesamte Licht aus der Leuchtzone III deaktiviert. Das gesamte Licht wird überwiegend durch die Leuchtzonen I, II erzeugt. Die Leuchtzonen I, II sind im Gegensatz zu III nahezu komplett aktiviert, wie die Sicht auf die Lichtaustrittsfläche gemäß Figur 6b zeigt. Schwarz markierte LEDs sind wiederum nicht aktiviert.When working two operators (Schatter 4 according to Figure 6a ) under the operating light 1 side to a deep wound, as indicated by the tube 3, almost all the light from the light emitting zone III is deactivated. The entire light is predominantly generated by the luminous zones I, II. The luminous zones I, II are almost completely activated in contrast to III, as shown by the view of the light exit surface according to FIG. 6b . Black marked LEDs are again not activated.

Weitere Beleuchtungssituationen mit verschiedenen Hindernissen im Strahlengang sind durch angepasste Lichtverteilungen optimierbar. In jedem festgelegten Schaltzustand verfügt dabei die Leuchte über die gleiche Beleuchtungsstärke Ec.Further lighting situations with different obstacles in the beam path can be optimized by means of adapted light distributions. In each specified switching state, the luminaire has the same illuminance E c .
