Oerät for illuminating cavities • lner device sum collecting the outgoing rays from the light source "

The brewing pattern concerns a device ssura lighting of cavities, spoons consisting of ela-white body cavities from a device for collecting the emanating from the light source and onto the end face of a light guide to be imaged rays by means of an optical system »which, for example, consists of a concave mirror and a condenser "

The illumination of cavities or body cavities for examination or photography has through the Creation of flexible light guides consisting of fiber bundles has taken an advantageous development because it was thereby made possible to guide the light rays from such light sources into the body cavity au that separated arranged by the examination or treatment device are. Above all, the flexible light guides make it possible to use strong light sources, which for structural reasons not at the investigation or Treatment device could be attached by yourself *

But the separate arrangement of the light sources also has certain limits, for example because of strong Incandescent lamps the lamp filament occupies an area that is larger than the cross section of an endoscope Usually used light guide · In the most favorable case possible imaging of the Lanroen helix on the end face of a light guide, the radiation area is therefore larger than the cross section of the light guide. This means that not all of the light rays emanating from the light surface are on the end face of the light guide can be mapped and a larger part of these light rays remains unused «

The device according to the utility model has the task of reducing the loss of light when using light sources to avoid a larger radiation surface in connection with light guides with a smaller cross-section. This is because of this achieves that the radiation axis of the optical system is aligned obliquely to the radiation surface of the light source is. In order to be able to guide the optimal light yield through the light guide in each case, the arrangement is like this taken that the angular position of the radiation axis of the optical system to the radiation surface of the light source is changeable. However, the arrangement can also be made so that the radiation surface of the light source is adjustable to the radiation axis of the optical system.

The inclination of the radiation axis of the optical System allows for the radiation surface of the light source an image gathering of the radiation surface and consequently a reduced image of the radiation surface on the face of the! light guide

In the drawing, the device is shown schematically in two different exemplary embodiments illustrated, namely show

iiff.1 the light source with a single

optical system and
Pig.2 the light source with a double optical system.

In the illustrated embodiments, the light source consisting of an incandescent lamp is indicated by 3, its flat Radiation surface with 4, the concave mirror with 5, the condenser with 6 and the light guide with 7

The radiation surface 4 of the light source 3 is usually perpendicular to the radiation axis of the optical system, which runs from the hollow joint 5 via the condenser 6 to the light guide 7 and is indicated by a dash-dotted line »The plane of the radiation surface 4 is therefore usually parallel to the end face 8 of the light guide 7 aligned · Since the radiation surface 4 is larger than the cross section of the light guide 7, not all

light rays emanating from the radiation surface 4 are shown on the end face 8 of the light guide.

In the exemplary embodiment shown in FIG. 3? the optical system as a whole can be adjusted with respect to the radiation surface 4 and aligned at an angle to it, so that the image of the radiation surface 4, which is reflected from the concave mirror and from the condenser 6 on the end face 8 of the light guide is thrown, is correspondingly reduced, with the gathering of the rays and their complete coverage enables a greater light output

As 3? I £ .2 shows, the inclination of the radiation surface 4 and, through the arrangement of two or more optical systems, the light yield even can be doubled or multiplied. Thereby each of the optical systems is with respect to the orientation their radiation axis to the radiation surface of the light source adjustable to according to the size of the Radiation surface of the light source to be able to achieve the most favorable setting of the optical system in each case »

The embodiment shown in Pig * 2 sees the arrangement of two optical systems. Other optical systems whose radiation axis is also through the Radiation surfaces 4 can easily be provided
