 wenn jede Linse einzeln   schwenkbar   ist und abwechselnd oder in Kombination miteinander in den Strahlengang eingeschaltet werden kann. 



   Die gelenkige Verbindung zwischen   Stirnbinde   und Stirnlampe in den gezeichneten Ausführungsformen, also die Kugel 6, steht meistens in symetrischer Lage zwischen beiden Augen, so dass je nach der Gewöhnung des Un ! ersuchenden das Sehloch 8 vor das linke oder das rechte Auge gebracht wird. Hieraus resultiert eine Stellung des Sehloches 8 zur Kugel   6,   die schematisch in Fig. 3 und 4 gezeichnet ist, u. zw. Fig. 3 vor dem linken Auge und Fig. 4 vor dem rechten Auge, in beiden Fällen vom Patienten aus gesehen. Die beste Art der Beleuchtung und Betrachtung resultiert in diesen Fällen, wenn die Beleuchtungsachse median vom Sehloch gelegen ist, was durch die Schwenkbarkeit des Gehäuses 3 um den Zapfen 9 erreicht wird.

   Dabei sind die   Abstandsverhältnisse   so gewählt, dass die Beleuchtungsachse möglichst in der Ebene der Augenpupille zu liegen kommt. 



   PATENT-ANSPRÜCHE :
1. Beleuchtungsapparat, insbesondere für medizinische Zwecke,   dadurch gekennzeichnet,   dass die Achse   Glaskörper-Metallfassung in   einem Winkel von ungefähr   900 zur Achse   einer

 when each lens can be pivoted individually and switched into the beam path alternately or in combination with one another.



   The articulated connection between the head bandage and the headlamp in the illustrated embodiments, i.e. the ball 6, is usually in a symmetrical position between the two eyes, so that depending on how accustomed the Un! requesting the eye hole 8 is brought in front of the left or right eye. This results in a position of the eye 8 to the ball 6, which is shown schematically in Fig. 3 and 4, u. between Fig. 3 in front of the left eye and Fig. 4 in front of the right eye, seen from the patient in both cases. The best type of lighting and viewing results in these cases when the lighting axis is located median of the viewing hole, which is achieved by the pivotability of the housing 3 about the pin 9.

   The spacing relationships are selected in such a way that the illumination axis comes to lie as far as possible in the plane of the eye pupil.



   PATENT CLAIMS:
1. Lighting apparatus, especially for medical purposes, characterized in that the axis of the glass body-metal mount at an angle of approximately 900 to the axis of a

Claims

2. Lighting apparatus according to claim 1, characterized in that the optical device (2) connected to the incandescent lamp (1) is connected to a perforated plate (5) in a known manner for the inevitable approximation of the beam cone axis to the visual axis of the observing eye is hingedly connected to a carrier.

3. Lighting apparatus according to claims 1 and 2, characterized in that the center of rotation of the part of the articulated connection which is fixedly connected to the plate (5) or to the lighting apparatus is arranged so that it lies in front of the plane of the plate.

4. Lighting apparatus according to claims 1 to 3, characterized in that the optical device connected to the incandescent lamp is pivotably arranged such that the beam cone axis is located approximately in the plane of the eye pupil and median of the observing eye. EMI2.2
