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 light sources for Generation of a light field.

Eine derartige Operationsleuchte ist beispielsweise durch die DE 198 38 627 A1 bekannt geworden.Such a surgical lamp is for example by DE 198 38 627 A1 become known.

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 light has at least one radiation source and at least two reflectors. To form a shadow-poor Illumination field hits radiation exiting the operating light with at least two different angles of incidence on the Illumination field on. The angles of incidence of the radiation are through Change the distance between at least two reflectors or adjustable 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 of the illuminated field form (which on the Operating table illuminated area) is at a surgical light after the Teaching of the prior art not provided.

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. The disadvantage is therefore that in the central beam path - between the Light emission surface of the surgical light and surgical wound - 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 to a surgical light create, 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 an operating light according to claim 1 solved. The basic principle is central light modules or Turn off the light source of a light source or dim it to the extent that no shadow can emerge in the light field. Obstacles that are in the The optical axis of the lighting system will be located both central and also from the edge of light components of the light exit surface of the Surgical light illuminated. Those lights that the shadow cause them to be hidden or turned off. The core shadow in the The light field is emitted by light passing from the side of the obstacle Rim area of the lamp body brightened. While central Light components can be reduced, light components from the edge areas the light exit surface are reinforced.

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 formation of the core shadow can be resolved in so-called Lighting systems (multiple individual headlights) by switching off the central Headlamps, or for the illumination of the central area competent illuminant (e.g., systems of several superimposed arranged lamps, belt lenses and / or Fresnel lenses) avoided become.

Diese Abschaltung kann bevorzugt manuell oder auch durch eine Sensor gestützte automatische Hinderniserkennung erfolgen.This shutdown can preferably manually or by a sensor supported 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) can only arranged in the edge areas headlights or the bulbs responsible for the light emission from the edge areas of the Light exit surface are responsible, be turned on. It will be possibly resulting core shadow areas clearly brightened. in the further course of the operation (deeper penetration into the body of the patient) is increasingly required depth light, which by turning on the central headlights or by centrally from the lamp body Exiting light is provided.

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 become. A dimming can be caused by a change of the bulbs supplied electric current and / or the electric voltage be generated. Alternatively, diaphragms, lenses or optical filters, which can be moved into the radiation entrance, a Change the luminous flux cause.
