Description

Verfahren zur Herstellung von Beleuchtungskörpern unter Verwendung lumineszierender Substanzen.Method of making lighting fixtures using luminescent substances.

Zusatz zum Patent 407944. Luminesziefende Stoffe, besonders fluoreszierende Präparate, also Körper, die unter Bestrahlung mit irgendwelchen Lichtquellen selbstleuchtend werden, können, da sie gemäß der Stoo:kesschen Regel längerwelliges Licht als dasjenige, durch welches sie selbst zur Fluoreszenz .erregt werden, ausstrahlen, die Lichtstärke der .erregenden Lichtquellen dadurch wesentlich verstärken, da.ß das von ihnen ausgesandte Fluoreszenzlicht in der Nähe des physiologischen Reizmaximums zu liegen kommt. Auf diesem Wege gelingt es z. B., die teilweise im unsichtbaren Spektralgebiet liegende Strahlung der seit kurzem in die Beleuchtungstechnik eingeführten Neon-oder allgemein Edelgasglimmli,chtlampen bedeutend zu verstärken. Aber auch. die weniger auf das mensehliche Auge wirkenden, Lichtemissionen beliebiger anderer Lichtquellen, z. B. auch die der sogenannten radioaktiven Leutchtfarben, ebenso wie das Licht Geißlerscher Röhren oder von Kohlen- und Metallfadenlampen können auf die geschilderte Weise in technisch wertvoller Art verstärkt werden.Addition to patent 407944. Luminescent substances, especially fluorescent ones Preparations, i.e. bodies that become self-luminous when irradiated with any light sources because, according to the Stoo: kess rule, they can have longer-wave light than that by which they themselves are excited to fluorescence, emit, the light intensity of the exciting light sources by the fact that the emitted by them Fluorescent light comes to lie in the vicinity of the physiological maximum stimulus. on this way it succeeds z. B., which partially lies in the invisible spectral region Radiation of the neon or general, recently introduced into lighting technology Noble gas glimmli, chtlampen significantly to amplify. But also. the less on that human eye acting, light emissions from any other light sources, z. B. also those of the so-called radioactive Leutchtfarben, as well as the light by Geißlerscher Tubes or carbon and metal filament lamps can be used in the manner described be reinforced in a technically valuable way.

Es ist schon vorgeschlagen worden, lumineszenzfähige Stoffe, Erdalka'isulfide u. dgl. in durchscheinenden Schichten auf die Umhüllungen einer Lichtquelle bzw. auf Reflektoren aufzutragen, wobei entweder auf gute Fluoreszenzwirkung während der Bestrahlung oder auf nachleuchtende Phosphoreszenz hingearbeitet wurde.It has already been proposed to use luminescent substances, alkaline earth sulfides and the like in translucent layers on the envelopes of a light source or to apply to reflectors, either while on good fluorescent effect the irradiation or afterglow phosphorescence was worked towards.

Überraschenderweise ergab sich nun, daß die nach Patent 407944 hergestellten Borphosphore sich in ganz besonderem Maße als Lumineszenzschicht zur Umhüllung von Lichtquellen sowie als Reflektorbelag eignem. Die neuen Stoffe verwandeln nicht nur kurzwellige Strahlen unter Fluoreszenzerscheinung in stark sichtbares Licht, sondern zeigen auch ein ,äußerst heftiges Nachleuchten, das im Gegensatz zum Fluoreszenzlicht als Phosphoreszenzlicht zu bezeichnen ist.Surprisingly, it has now been found that the manufactured according to patent 407944 Boron phosphors are particularly useful as a luminescent layer to coat Light sources as well as reflector coverings. The new fabrics do not transform only short-wave rays with the appearance of fluorescence in strongly visible light, but also show an extremely intense afterglow, which in contrast to fluorescent light is to be referred to as phosphorescent light.

Der Borsäureflu:oreszeinphosphor z. B. läßt sich leicht in durchscheinender Schicht auf Glas auftragen, ebenso natürlich auch auf Quarz, und kann dann von beliebigen Lichtquellen durchstrahlt werden und das stark auf das Auge wirkende Fluoreszenzlicht dieses Phosphores in der oben beschriebenen Weise benutzt werden. Nach dem Ausschalten der erregenden Lichtquelle und somit der Beendigung der Fluoreszenz greift ein ganz außerordentlich starkes Nachleuchten des Phosphors Platz. Auf diese Weise kann der nach Ausschalten der Lichtquelle etwa zu verlassende Raum eine Zeitlang beleuchtest werden.The boric acid flu: oreszeinphosphor z. B. can be easily converted into translucent Apply a layer to glass, and of course also to quartz, and then you can use any Light sources are irradiated and the fluorescent light acting strongly on the eye this phosphor can be used in the manner described above. After switching off the exciting light source and thus the termination of the fluorescence takes hold extremely strong afterglow of the phosphorus square. In this way, the after switching off the light source, illuminate the room to be left for a while will.

Aber auch auf spiegelnder Fläche, auf geeigne;er Unterlage aufgetragen, können Bor- @äurephospliore in der geschilderten Art benutz, werden, iiidein nun nicht das durchscheineride, sondern das reflektierte Fluoreszenz- bzw. Phosphoreszenzlicht Verwendung findet.But also on a reflective surface, applied on a suitable surface, can boron @ äurephospliore are used in the manner described, iiidein not the translucent, but the reflected fluorescence resp. Phosphorescent light is used.

Die neuen Lumineszenzlampen können auch für ganz spezielle Zwecke benutzt werden, so z. B. auf medizinischem Gebiet in der Bestrahlungstherapie, wobei die keimtötenden Wirkungen der fluoreszierenden Stoffe aus--enutzL werden.The new luminescent lamps can also be used for very special purposes be used, e.g. B. in the medical field in radiation therapy, wherein the germicidal effects of the fluorescent substances can be exploited.

Auch als Photometer werden solche Lampen brauchbar sein, da, unabhängig von der erregenden Lichtquelle, das emittierte Licht völlig konstant ist.Such lamps will also be useful as photometers, there, independently from the exciting light source, the emitted light is completely constant.

Bei den mit Wechselstrom betriebenen Glimmlichtlampen erstreckt sich die durch die Erfindung bedingte Verbesserung auch auf die Beseitigung des Flimmerns. Es, werden nämlich durch das starke Nachleuchten der Borphosphore die nicht leuchtendem Zwischenphasen, die eine Folge des Stromwechsels sind, überbrückt.In the case of glow lamps operated with alternating current, the improvement brought about by the invention also applies to the elimination of flicker. Because of the strong afterglow of the boron phosphors, the non-luminous ones become Intermediate phases, which are a consequence of the current change, bridged.
