"Light generator for medical purposes"

The invention relates to a light generator for medical use Purposes with a housing, a light source and a light exit opening, in particular for wavelengths in the range from 400 nm to 800 nm.

From the German patent application P 30 23 266 is a Known retractors for surgical purposes made of light-conducting material. A light guide is attached to this retractor and this in turn to a radiation source (light generator) connected. The known light generators only contain one that can be mechanically displaced for replacement Light source and a single socket for receiving the light guide.

This means that during an operation that involves two retractors are necessary, a second light generator or a branched light guide must be added. One falls If the light source is off, the light source must be removed from the housing and a new one inserted, or a mechanical one Moving can be made.

The object of the invention is to provide a light generator create, which allows the connection of several light guides and in the event of failure of a light source quickly is ready for operation again.

The task for a light generator is solved characterized type according to the invention in that the housing has at least two light exit openings in a wall in the form of a socket, of which Light exit openings seen from in the direction of the opposite wall of the housing, behind each light exit opening one light source is immovably connected to the wall. The housing advantageously has three socket-like light exit openings and three Light sources on. The light exit openings are expedient arranged in one plane. A perforated plate is preferably located in the housing below the light sources and arranged below a fan. The wall advantageously has a removable cover in the area of the light sources. The housing is expediently in the wall with a power switch and in the wall with it the light exit openings with a brightness control button Mistake.

The advantages of the light generator designed according to the invention lie in the fact that a malfunction in the event of a light source failure can be rectified quickly and easily, that no replacement lamp, then when the device is urgently needed is, must be used and that the device has several Has sockets for light guides and is therefore space-saving.

An embodiment is shown in the drawings, Figure 1 shows a light generator housing, wherein in the figure la the front view, in the figure Ib a Longitudinal section and a horizontal section in FIG are shown at the level of the light exit openings. Figure 2a shows the attachment of the light generator on a tripod and the attachment to a wall arm is in Figure 2b and shown on a ceiling arm in Figure 2c.

In FIG. La, the housing 2 has three ^{light exit openings la, Ib and Ic arranged next to one another in the wall 2 1} , into which the ends of the light guides are inserted if necessary, as well as an operating button 3 for regulating the brightness. FIG. 1b shows a light source 4 arranged behind a light exit opening 1, as well as the brightness regulator 5 with control button 3, the mains transformer 7, the mains switch 6 and the connector 8 for attachment to a stand or bracket. To cool the light sources 4a, 4b, 4c, a perforated plate 13 is arranged below the light sources and a fan 14 is arranged below it. FIG. Ic shows the arrangement of the light sources 4a, 4b and 4c, as well as the light exit openings la, Ib and Ic. The light exit openings la, Ib, Ic have actuating pins 20 for microswitches 9 for actuating the light sources. Halogen reflector lamps 10 in a connection part with cooling fins 12 for filter glass holders are used as light sources. To replace the light sources 4a, 4b, 4c, the cover 15 is designed to be removable on the rear side 1 /. The light generator 2 can be attached to a tripod or to a wall arm 22 or ceiling arm 23 according to FIG.
