Abstract

Eine Operationsleuchte ist mit einem inneren Leuchtenkörper (6) versehen, der wenigstens eine Entladungs-Lampe (7) und einen inneren Reflektor in einem Gehäuse aufweist, wobei der Leuchtenkörper wenigstens teilweise von einem äußeren ringartigen Gehäuse mit einem ring-oder polygonartig ausgebildeten Reflektor (9) zur konvergierenden Umlenkung von aus dem Leuchtenkörper austretendem Licht in ein Beleuchtungsfeld umgeben ist. Der äußere Reflektor (9) weist auf seiner zum inneren Leuchtenkörper (6) gerichteten Seite eine geschlossene, transparente Fläche auf, deren Rückseite an eine reflektierende Schicht (17) angrenzt; die reflektierende Schicht ist auf die Rückseite der transparenten Fläche aufgebracht. Der innere Leuchtenkörper (6) und der äußere Reflektor (9) werden durch einen Verbindungssteg (3) zusammengehalten, welcher mit einem Bügel (4) zur Befestigung an einer stationären Halterung gelenkig verbunden ist.An operating light is provided with an inner light body (6) which has at least one Discharge lamp (7) and an inner reflector in a housing, the Luminaire body at least partially from an outer ring-like housing with a ring or polygonal reflector (9) for converging deflection from the Luminaire body is surrounded by emerging light in a lighting field. The outer reflector (9) has on its side facing the inner lamp body (6) a closed, transparent surface, the back of which abuts a reflective layer (17); the reflective Layer is applied to the back of the transparent surface. The inner one Luminaire body (6) and the outer reflector (9) are held together by a connecting web (3), which with a bracket (4) for attachment to a stationary bracket is articulated.

Es ist somit möglich, eine Operationsleuchte mit hoher Beleuchtungsintensität zu schaffen, die einerseits Licht aus einem großen Durchmesser und andererseits aus einem kleinen Durchmesser ins Beleuchtungsfeld bringt, um sowohl enge Wundkanäle gut auszuleuchten, als auch eventuelle Hindernisse gut zu hinterstrahlen. Darüber hinaus ist der Leuchtenkörper kompakt aufgebaut und für eine laminare Strömung zur Vermeidung von Verunreinigungen in der Umgebung des Operationsfeldes geeignet.

Figure 00000001
It is therefore possible to create an operating light with high lighting intensity, which on the one hand brings light from a large diameter and on the other hand from a small diameter into the lighting field in order to both illuminate narrow wound channels and also to backlight any obstacles. In addition, the luminaire body is compact and suitable for a laminar flow to avoid contamination in the area surrounding the operating field.
