Abstract

Um eine hohe Ausfallsicherheit bei Leuchten für medizinische Anwendungen, insbesondere Operationsleuchten, zu erzielen, werden zwei elektrische Lampen (5,7) in jeweils einen als Ellipsoid ausgebildeten Hohlspiegel als Teil eines Reflektors (1) eingesetzt, wobei die beiden Hohlspiegel (2,3) Brennpunkte (6,8) aufweisen, die entlang einer optischen Achse (4) zueinander ausgerichtet sind. Der für die Funktion einer Hauptleuchte vorgesehene Hohlspiegel (3) ist als Ringreflektor ausgebildet, während der für die Reserveleuchtenfunktion vorgesehene Hohlspiegel (2) den Reflektor (1) auf der zur Lichtaustrittsrichtung abgewandten Seite abschließt. Somit bleibt bei einem Wechsel vom Hauptleuchten-Betrieb zum Reserveleuchten-Betrieb das beleuchtete Feld (14) in seiner Größe wenigstens näherungsweise erhalten und der Ort ändert sich nicht (X,Y-Richtung).To ensure a high level of reliability for lights for medical applications, in particular To achieve surgical lights, two electric lamps (5,7) each in one as an ellipsoid trained concave mirror used as part of a reflector (1), the two concave mirrors (2, 3) Have focal points (6, 8) which are aligned with one another along an optical axis (4). The The concave mirror (3) provided for the function of a main lamp is designed as a ring reflector, while the concave mirror (2) provided for the reserve lamp function, the reflector (1) on the to the side facing away from the light exit direction. So there is a change from Main light operation for reserve light operation the illuminated field (14) in its size at least approximately preserved and the location does not change (X, Y direction).

Die Hauptleuchte weist entweder eine Entladungslampe oder eine Halogen-Glühlampe auf, während die Reservelampenfunktion stets von einer Halogen-Glühlampe wahrgenommen wird.
