Description
Beleuchtungsvorrichtung für Röntgenzimmer zur Durchleuchtung im erhellten Raume Es ist bereits eine Vorrichtung zur Röntgendurchleuchtung im erhellten. Raume beschrieben, die dadurch gekennzeichnet ist, daß man den Durchleuchtungsschirm mit einem Farbfilter bedeckt, der das unter Einwirkung der Röntgenstrahlen entstehende Eigenlicht des Leuchtschirmes ungehindert hindurchläßt, während alle anderen Strahlen von demselben absorbiert werden und gleichzeitig den übrigen Raum in einer komplementären Farbe beleuchten.Illumination device for X-ray rooms for fluoroscopy in the lighted Rooms There is already a device for fluoroscopy in the lighted. Spaces described, which is characterized in that the fluoroscopic screen with covered with a color filter, which is created under the action of the X-rays The own light of the fluorescent screen lets through unhindered, while all other rays be absorbed by the same and at the same time the rest of the space in a complementary Illuminate color.
Trotz vieler Vorteile beim'IArbeiten in einem solchen komplementär zur Schirmleuchtfarbe erleuchteten Röntgenzimmer bestand noch der Nachteil, daß vom Beschauer des Schirmes oder von Gegenständen in seiner Nähe störende Reflexe an dem Schirm bzw. des ihn bedeckenden Bleiglases auftraten, welche das Röntgenbild beeinträchtigten.Despite the many advantages of working in such a complementary way There was still the disadvantage that the X-ray room illuminated in the fluorescent color of the screen reflections from the viewer of the screen or from objects in its vicinity appeared on the screen or the lead glass covering it, which the X-ray image impaired.
Es wurde nun gefunden, daß man durch bestimmte Anordnung der Lichtquelle zu einer Beleuchtungseinrichtung gelangt, die zwar das Arbeiten im erhellten Raum gestattet, aber .gleichzeitig das Auftreten solcher störender Spiegelungen vermeidet.It has now been found that a certain arrangement of the light source arrives at a lighting device that allows working in the lighted room allowed, but at the same time avoids the occurrence of such disturbing reflections.
Es sind schon zahlreiche Einrichtungen, insbesondere zur Beleuchtung von Sälen für Lichtbildvorführungen, beschrieben, sie können jedoch alle nicht dem vorliegenden Zweck dienen, da die gestellten Anforderungen bei der Röntgendurchleuchtung ganz andere sind.There are already numerous facilities, especially for lighting of halls for slide shows, but none of them can serve the present purpose, as the requirements placed on fluoroscopy are completely different.
Die Lösung der gestellten Aufgabe gemäß der Erfindung kann an Hand der Zeichnung leicht verfolgt werden. Sie wird im wesentlichen durch folgende Punkte bedingt Die Anordnung bzw: Abblendung der Lampe geschieht in der Weise, daß vor direkten Strahlen alle die Stellen bzw. Gegenstände des Raumes geschützt werden, von denen durch Reflexion am Leuchtschirm bzw. dem ihn bedeckenden Bleiglase Strahlen in das Auge des Beschauers gelangen könnten.The solution to the problem posed according to the invention can be based on hand the drawing can be easily traced. It is essentially based on the following points conditional The arrangement or: dimming of the lamp happens in such a way that before direct rays all the places or objects in the room are protected, of those by reflection on the luminescent screen or the lead glass covering it rays could get into the eye of the beholder.
Andere Strahlen, die durch Reflexion am Bleiglas nicht das Auge des Beschauers, sondern andere beliebige Stellen des Raumes treffen, sind natürlich unschädlich. Die Zeichnung gibt beispielsweise eine Anordnung wieder, die den obigen Anforderungen entspricht. Es sind d-y und d-s die äußersten Strahlen des von d ausgehenden Lichtkegels. Weiter sind n-o und P-q Grenzstrahlen, die bei der Reflexion an der Glasscheibe noch in das Auge c gelangen können. Von der Lichtquelle d ausgehende Strahlen müssen also, vom Beschauer gesehen, jenseits dieser Grenzstrahlen n-o und P-q verlaufen. Die neue Beleuchtungseinrichtung läßt sich beim Arbeiten sowohl mit Farbfilter nach Patentschrift 350 505 wie auch mit einer Grünbrille nach Patentschrift a98 295 verwenden.Other rays that do not hit the beholder's eye due to reflection on the lead glass, but any other point in the room, are of course harmless. The drawing shows, for example, an arrangement that meets the above requirements. Dy and ds are the outermost rays of the cone of light emanating from d. Furthermore, no and Pq are boundary rays that can still get into the eye c when they are reflected on the glass pane. Rays emanating from the light source d must therefore, as seen by the viewer, run beyond these limit rays no and Pq. The new lighting device can be used when working with both a color filter according to patent specification 350 505 and green glasses according to patent specification a98 295 .
