Description
steht Zwischen den beiden Teilen 20a, 206 befindet sich ein Spalt 18, der möglichst eng sein sollte. In den Spalt 18 kann eine als Lichtverschluß dienende Lichtblende 22 ein- und ausgefahren werden. Der der Strahlungsquelle 10 benachbarte Teil 20a des Lichteintrittsfensters ist fest in einem Lichtkasten auf zwei Lagern 24, 26 befestigt und hat möglichst geringen Abstand zum Lampenkolben (z. B. einen Abstand von 1 mm) und zum anderen Fensterteil 206. Der Durchmesser des Fensterteils 20a kann etwas größer sein als der des Fensterteils 206, was die Einjustierung des Lichtleiters erleichtert Die beiden Teile des Fensters sind vorzugsweise aus Quarzglas hergestellt Der Schlauch 14 ist durch ein mechanisches Element 28 auf den Teil 206 des Lichteintrittsfensters 12 aufgedichtetBetween the two parts 20a, 206 there is a gap 18 which should be as narrow as possible. In the gap 18, a light screen 22 serving as a light shutter can be retracted and extended. That of the radiation source 10 adjacent part 20a of the light entry window is firmly attached in a light box on two bearings 24, 26 and has the smallest possible distance to the lamp bulb (e.g. a distance of 1 mm) and to the other Window part 206. The diameter of the window part 20a may be slightly larger than that of the window part 206, whatever the adjustment of the light guide facilitates the two parts of the window are preferably made of quartz glass The tube 14 is attached to the part 206 of the light entry window 12 by a mechanical element 28 put up
Wie F i g. 2 zeigt, enthält die Beleuchtungseinrichtung ein Austrittsfenster 30 aus zwei durch einen Spalt 32 getrennten, koaxialen in Strahlrichtung hintereinanderliegenden Teilen 30a und 306. Der der Strahlungsquelle zugewandte Teil 30a des Austrittsfensters verschließt das lichtaustrittsseitige Ende des Kunststoffschlauches 14, der auf das Teil 30a durch ein mechanisches Element 34 aufgedichtet ist Das der Lichtquelle abgewandte Teil 306 ist gekrümmt und in einer Hülse 36 befestigt, die auf das Lichterleiterende aufgesteckt werden kann, wobei der Spalt 32 zwischen den Teilen 30a und 306 möglichst eng sein soll (z. B. 1 mm). Die Hülse 36 ist drehbar auf dem Ende des Lichtleiters gelagert, so daß das gekrümmte Teil 306 verdreht und die Strahlung bequem auf einen gewünschten Punkt gerichtet werden kann. Der der Strahlungsquelle abgewandte Teil 306 des Lichtaustrittsfensters kann einen etwas größeren Durchmesser als das der Lichtquelle zugewandte Teil 30a haben, um die durch den Spalt 32 auftretenden Lichtverluste möglichst klein zu halten.Like F i g. 2 shows contains the lighting device an exit window 30 made up of two coaxial ones, separated by a gap 32, one behind the other in the direction of the beam Parts 30a and 306. The part 30a of the exit window facing the radiation source closes the end of the plastic tube 14 on the light exit side, which is attached to the part 30a by a mechanical element 34 is sealed. The part 306 facing away from the light source is curved and fastened in a sleeve 36 which extends on the light guide end can be attached, the gap 32 between the parts 30a and 306 as possible should be narrow (e.g. 1 mm). The sleeve 36 is rotatably mounted on the end of the light guide, so that the curved Part 306 twisted and the radiation can be conveniently directed to a desired point. The part 306 of the light exit window facing away from the radiation source can be somewhat larger Have a diameter than the part 30a facing the light source, around those occurring through the gap 32 To keep light losses as small as possible.
