Abstract

The operating light is composed of a number of hexagonal modules [1] that form a dish shaped unit with light [4] focussed onto a surface. Each module has a number of light sources, such as light emitting diodes, LED. An obstruction [2] in the centre may occur causing a shadow and for this the centre module [1f] output may be dimmed or turned off.

Description

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

Eine derartige Operationsleuchte ist beispielsweise durch die DE 198 38 627 A1 bekannt geworden. Aus der Druckschrift US 2003/0185009 A1 ist eine gattungsgemässe Operationsleuchte bekannt, bei der Mittel zum Ausschalten oder Dimmen des Lichtes vorgesehen sind.Such a surgical light is, for example, by the DE 198 38 627 A1 known. From the publication US 2003/0185009 A1 is a generic operating light known, are provided in the means for switching off or dimming of the light.

Die bekannte Operationsleuchte weist wenigstens eine Strahlungsquelle und wenigstens zwei Reflektoren auf. Zur Bildung eines schattenarmen Beleuchtungsfeldes trifft aus der Operationsleuchte austretende Strahlung mit wenigstens zwei unterschiedlichen Einfallswinkeln auf das Beleuchtungsfeld auf. Dabei sind die Einfallswinkel der Strahlung durch Änderung des Abstandes zwischen wenigstens zwei Reflektoren oder zwischen einem Reflektor und der Strahlungsquelle einstellbar.The known surgical lamp has at least one radiation source and at least two reflectors. To form a low-shadow illumination field, radiation emerging from the operating light impinges on the illumination field with at least two different angles of incidence. The angles of incidence of the radiation are adjustable by changing the distance between at least two reflectors or between a reflector and the radiation source.

Die applikationsbezogene Veränderung der Leuchtfeldform (die auf dem Operationstisch beleuchtete Fläche) ist bei einer Operationsleuchte nach der Lehre des Standes der Technik nicht vorgesehen.The application-related change in the light field shape (the illuminated on the operating table surface) is not provided in a surgical lamp according to the teaching of the prior art.

Bestehende Operationsleuchten weisen eine feste Lichtverteilung auf. Nachteilig ist daher, dass sich im zentralen Strahlengang - zwischen der Lichtaustrittsfläche der Operationsleuchte und der Operationswunde - befindende Hindernisse einen Schatten im Lichtfeld erzeugen.Existing operating lights have a fixed light distribution. A disadvantage is therefore that in the central beam path - between the light exit surface of the surgical light and the surgical wound - located obstacles create a shadow in the light field.

Der Anmelder hat sich die Aufgabe gestellt, eine Operationsleuchte zu schaffen, welche ein schattenarmes Lichtfeld erzeugen kann.The Applicant has set itself the task of creating a surgical light, which can produce a low-shadow light field.

Diese Aufgabe wird durch eine Operationsleuchte gemäß Patentanspruch 1 gelöst. Das Grundprinzip besteht darin, zentrale Lichtmodule oder Leuchtmittel einer Lichtquelle auszuschalten oder soweit zu dimmen, dass kein Schatten im Lichtfeld entstehen kann. Hindernisse, welche sich in der optischen Achse des Lichtsystems befinden werden sowohl von zentralen als auch von vom Rand kommenden Lichtanteilen der Lichtaustrittsfläche der Operationsleuchte beleuchtet. Diejenigen Lichtanteile, welche den Schatten verursachen, werden ausgeblendet oder ausgeschaltet. Der Kernschatten im Lichtfeld wird durch seitlich am Hindernis vorbeistrahlendes Licht aus den Randbereichendes Leuchtenkörpers aufgehellt. Während zentrale Lichtanteile reduziert werden, können Lichtanteile aus den Randbereichen der Lichtaustrittsfläche verstärkt werden.This object is achieved by a surgical lamp according to claim 1. The basic principle is to switch off central lighting modules or light sources of a light source or dim them so far that no shadow can arise in the light field. Obstacles, which are located in the optical axis of the light system, are illuminated both by central and marginal light components of the light exit surface of the surgical light. Those parts of the light which cause the shadow are hidden or switched off. The core shadow in the light field is brightened by light radiated past the obstacle from the edge regions of the lamp body. While central light components are reduced, light components from the edge regions of the light exit surface can be amplified.

Die Entstehung des Kernschattens kann bei so genannten aufgelösten Lichtsystemen (mehrere Einzelscheinwerfer) durch Abschalten des zentralen Scheinwerfers, bzw. des für die Ausleuchtung des zentralen Bereiches zuständigen Leuchtmittels (z.B. Systeme aus mehreren übereinander angeordneten Lampen, Gürtellinsen und/oder Fresnellinsen) vermieden werden.The emergence of the core shadow can be avoided in so-called dissolved light systems (multiple individual headlamps) by switching off the central headlamp or illuminating the central area (e.g., multiple stacked lamp systems, belt lenses, and / or Fresnel lenses).

Diese Abschaltung kann bevorzugt manuell oder auch durch eine Sensor gestützte automatische Hinderniserkennung erfolgen.This shutdown can preferably be done manually or by a sensor-based automatic obstacle detection.

Zu Beginn der Operation (Arbeiten an der Körperoberfläche des Patienten) können lediglich die in den Randbereichen angeordneten Scheinwerfer bzw. die Leuchtmittel, die für den Lichtaustritt aus den Randbereichen der Lichtaustrittsfläche verantwortlich sind, eingeschaltet sein. Dabei werden eventuell entstehende Kernschattenbereiche deutlich aufgehellt. Im weiteren Operationsverlauf (tieferes Eindringen in den Körper des Patienten) wird zunehmend Tiefenlicht benötigt, welches durch Einschalten des zentralen Scheinwerfers bzw. durch zentral aus dem Leuchtenkörper austretendes Licht bereitgestellt wird.At the beginning of the operation (working on the body surface of the patient), only the headlamps arranged in the peripheral regions or the light sources which emit light from the edge regions of the light source can be used Light exit surface are responsible, be turned on. Any resulting shadow areas will be brightened up significantly. In the further course of the operation (deeper penetration into the body of the patient), increasingly deep light is required, which is provided by switching on the central headlamp or by light emerging centrally from the luminaire body.

Die Dimmung kann durch mechanische und/oder optische Mittel erreicht werden. Eine Dimmung kann durch eine Änderung des der Leuchtmittel zugeführten elektrischen Stroms und/oder der elektrischen Spannung erzeugt werden. Alternativ können Blenden, Linsen oder optische Filter, welche in den Strahleneingang hinein bewegt werden können, eine Veränderung des Lichtstromes bewirken.The dimming can be achieved by mechanical and / or optical means. A dimming can be generated by a change in the electrical current supplied to the lamp and / or the electrical voltage. Alternatively, diaphragms, lenses or optical filters that can be moved into the beam entrance can cause a change in the luminous flux.

Aus der Fig. 1a ist ersichtlich, dass einzelne Lichtmodule 1a bis 1g ein Leuchtfeld 3 erzeugen. Im Strahlengang der gestrichelt angedeuteten Lichtstrahlen 4a bis 4c befindet sich ein Hindernis 2. Das sich in der optischen Achse befindende Hindernis 2 wird von den zentralen, innerhalb des durch die Lichtstrahlen 4c begrenzten Lichtkegels getroffen, so dass sich ein Kernschatten 5 im Zentrum des Leuchtfeldes bildet.From Fig. 1a it is seen that individual light modules 1a to 1g generate a light field 3. An obstacle 2 is located in the beam path of the light rays 4a to 4c indicated by dashed lines. The obstacle 2 located in the optical axis is struck by the central light cone within the light cone delimited by the light beams 4c so that a core shadow 5 forms in the center of the light field ,

Gemäß Fig. 1b wurde das zentrale Lichtmodul 1f (siehe Fig. 1a) von der Lichterzeugung ausgenommen. Alternativ kann das zentrale Lichtmodul auch hinsichtlich der Lichtleistung gedimmt werden. Es werden im Wesentlichen nur die Lichtstrahlen 4a und 4b zur Erzeugung des Leuchtfeldes 3 verwendet, welche an dem Hindernis vorbeigehen. Dies kann beispielsweise durch eine Sensorik in Verbindung mit einer Steuerung durch oder Regelung verwirklicht werden. Es kommt zu keiner Kernschattenbildung.Referring to Fig. 1b , the central light module 1f (see Fig. 1a) has been excluded from light generation. Alternatively, the central light module can also be dimmed in terms of light output. Essentially, only the light beams 4a and 4b are used for generating the illuminated field 3, which pass by the obstacle. This can be achieved for example by a sensor in conjunction with a control by or regulation. There is no core shading.

Aus der Fig. 2a ist ersichtlich, dass einzelne Leuchtmittel 6a bis 6e ein Leuchtfeld 7 erzeugen. Im Strahlengang der gestrichelt angedeuteten Lichtstrahlen 8a bis 8c befindet sich ein Hindernis 9. Das sich in der optischen Achse befindende Hindernis 9 wird von den zentralen, innerhalb des durch die Lichtstrahlen 8c begrenzten Lichtkegels getroffen, so dass sich ein Kernschatten 10 im Zentrum des Leuchtfeldes 7 bildet.From Fig. 2 it can be seen that individual bulbs 6a to 6e produce a light box 7. In the beam path of the light beams 8a to 8c indicated by dashed lines, there is an obstacle 9 The optical axis obstacle 9 is struck by the central, within the bounded by the light beams 8 c light cone, so that a core shadow 10 is formed in the center of the light field 7.

Gemäß Fig. 2b wurde das zentrale Leuchtmittel 6e von der Beleuchtung ganz ausgenommen oder hinsichtlich der Lichtleistung so stark gedimmt, dass kein Kernschatten entstehen kann. Es werden im Wesentlichen nur die Lichtstrahlen 6a und 6b zur Erzeugung des Leuchtfeldes 7 verwendet, welche an dem Hindernis vorbeigehen. Dies kann beispielsweise durch eine Sensorik in Verbindung mit einer Steuerung durch oder Regelung verwirklicht werden.According to FIG. 2b , the central illuminant 6e has been completely excluded from the illumination or has been so dimmed with regard to the light output that no core shadow can arise. Essentially, only the light beams 6a and 6b are used to generate the light field 7, which pass by the obstacle. This can be achieved for example by a sensor in conjunction with a control by or regulation.

Aus der Fig. 3a ist ersichtlich, dass eine Lichtquelle 11 mit einzelnen von Linsen umgebenen Leuchtmitteln 12a bis 12c ein Leuchtfeld 13 erzeugen. Im Strahlengang der gestrichelt angedeuteten Lichtstrahlen 14a bis 14d befindet sich ein Hindernis 15. Das sich in der optischen Achse befindende Hindernis 15 wird von den zentralen, innerhalb des durch die Lichtstrahlen 14d begrenzten Lichtkegels getroffen, so dass sich ein Kernschatten 16 im Zentrum des Leuchtfeldes bildet.From Fig. 3 it can be seen that a light source 11 surrounded by individual lenses bulbs 12a to 12c generate a light field 13. An obstacle 15 is located in the beam path of the light beams 14a to 14d indicated by dashed lines. The obstacle 15 located in the optical axis is struck by the central light cone within the light cone 14d delimited by the light beams 14d so that a core shadow 16 forms in the center of the light field ,

Gemäß Fig. 3b wurde das zentrale Leuchtmittel 12c von der Lichterzeugung ganz ausgenommen oder hinsichtlich der Lichtleistung wesentlich gedimmt. Es werden im Wesentlichen nur die Lichtstrahlen 14a bis 14c zur Erzeugung des Leuchtfeldes 13 verwendet, welche an dem Hindernis 15 vorbeigehen. Dies kann beispielsweise durch eine Sensorik in Verbindung mit einer Steuerung durch oder Regelung verwirklicht werden. Es kommt zu keiner Kernschattenbildung.According to FIG. 3b , the central luminous means 12c has been completely excluded from the generation of light or substantially dimmed with regard to the light output. Essentially, only the light beams 14 a to 14 c are used for generating the illuminated field 13, which pass by the obstacle 15.
