Description

Beleuchtung von insbesondere mit großen Fenstern ausgestatteten Räumen bei Luftgefahr Die Erfindung betrifft die Beleuchtung von insbesondere mit großen Fenstern, Oberlichten usw. ausgestatteten Räumen bei Luftgefahr. Um solche Räume trotz heller Beleuchtung der Fliegersicht zu entziehen, ohne daß irgendwelche Verdunkelungsvorkehrungen getroffen werden müssen, ist bereits vorgeschlagen worden, die Fensterscheiben aus neodymhaltigem Glase herzustellen und für die Beleuchtung Natriumdampflampen zuverwenden.Illumination of rooms especially equipped with large windows if there is a risk of air The invention relates to the lighting of especially large Windows, skylights, etc. equipped rooms in case of air hazard. To such spaces To be withdrawn from the pilot's view despite bright lighting, without any darkening precautions Must be taken, it has already been proposed to remove the window panes Manufacture of neodymium-containing glass and to use sodium vapor lamps for the lighting.

Durch diese Anordnung wird erreicht, daß die von der Natriumdampflampe ausgehenden, nur im Gebiet der D--Linie des Spektrums liegenden Strahlen von dem im gleichen Gebiet absorbierenden Ncodym.glas an ihrem Durchtritt nach außen verhindert werden.This arrangement ensures that that of the sodium vapor lamp outgoing rays from the Ncodym.glass absorbing in the same area prevents it from passing through to the outside will.

Nun hat aber die gebräuchliche -'atriumdampflampe außer der Strahlung bei etwa 5S9 mu noch eine geringe Strahlung, die aus der Edelgasfüllung der Lampe her-.stammt. Diese Strahlung wirkt störend, denn sie wird durch das Neodymglas glatt hindurchgelassen. Ein Filter mit dem Fensterglas zu verbinden oder eine Filtersubstanz in das Fensterglas einzubringen, die ,die Strahlung des Edelgases absorbiert, hätte den Nachteil, daß bei Tage sehr viel von dem eindringenden Tageslicht zurückgehalten würde. Deshalb wird erfindungsgemäß vor die Natriumdampflampe ein Filter geschaltet, das die Edelgasstrahlung, die im wesentlichen die Wellenlängen 615 mu, 568 mu, 515 mu, q9omu aufweist, absorbiert. Durch dieses Filter wird das Licht der Natriumdampflampe nur in geringem Maße geschwächt, .so d.aß von der zur Lichterzettguing aufgewandten Energie ein viel größerer Teil der Beleuchtung zugfite kommt, als wenn z. B. Glühlampenlicht durch irgendwelche Lichtfilter gedämpft wird.But now the usual sodium vapor lamp has in addition to the radiation at around 5S9 there is still a small amount of radiation from the inert gas filling of the lamp comes from. This radiation has a disruptive effect because it is made smooth by the neodymium glass let through. To connect a filter to the window glass or a filter substance to be introduced into the window glass, which would have absorbed the radiation of the noble gas the disadvantage that during the day a great deal of the penetrating daylight is withheld would. Therefore, according to the invention, a filter is placed in front of the sodium vapor lamp, that is the noble gas radiation, which essentially has the wavelengths 615 mu, 568 mu, 515 mu, q9omu, absorbed. The light from the sodium vapor lamp passes through this filter Weakened only to a small extent, such as by the one spent on the Lichterzettguing Energy is a much larger part of the lighting than if z. B. Incandescent light is attenuated by some kind of light filter.

Ein Filter, das: die Strahlung des Edelgases der Natriumdampflampe absorbiert und das vorn Natrium emittierte licht der Wellenlänge 589 mu, hindur chlä ßt, kann z. ß. auf folgende Weise erhalten werden: Man löst für je ein Quadratdezimeter Filterfläche 5.2m- Chromotrop FB, 4,o mg Echtgrün GR, 192=m- Naphtholgrün, 3,o mg Flavazin L, 3,3 ing Croceinorange G, o,? n l-Säurefüchsin, 5,6 mg Neucoccin 11i q. e1113 Methanol, verdünnt mit a cm3 Aceton und vermischt diese Lösung mit 3 cms eines geeigneten Lackes. Die Mischung wird auf eine Glasplatte ausgegossen und getrocknet.A filter that: the radiation of the noble gas of the sodium vapor lamp absorbed and that light of wavelength emitted from sodium 589 mu, hindu, can z. ß. can be obtained in the following way: One solves for each one square decimeter filter area 5.2m- Chromotrop FB, 4, o mg real green GR, 192 = m- naphthol green, 3.0 mg flavazine L, 3.3 mg crocein orange G, o ,? n l-acid fox, 5.6 mg Neucoccin 11i q. e1113 methanol, diluted with a cm3 acetone and mixed this solution with 3 cms of a suitable varnish. The mixture is on a glass plate poured out and dried.

D,a dickere Scheiben des Neodym.glases bzw. Scheiben mit einem höheren Neodymgehalt verhältnismäßig kostspielig sind, kann man denselben Effekt auch mit einem geringeren Aufwand an Neodym erreichen, wenn man entweder durch Mattierung des Glases, beispielsweise von der Innenseite oder durch Versetzen des Glases mit einem Trübungsmittel 'bzw. durch beide Maßnahmen, den Lichtweg im Glase verlängert. Daneben wird hierdurch noch erreicht, daß spiegelnde Reflexe des Natriumlichtes, die durch irgendwelche Arbeitsvorgänge in dem Raum, z. B. beim Hantieren mit blanken Metallflächen, auftreten könnten, nicht in der gleichen Rich- tun- durch die Scheiben hinausdringen, son- dern allseitig zerstreut und dadurch ge- nügend verteilt werden utid daher unsicht- bar bleiben. Die Arbeit kann nun irr dem Raum ohne jede Störungen fortgesetzt «erden, während die Verdunkelung nach außen durch das neodymhaltige Glas so wirksam ist, daß alle auch bei unmittelbarer Luft-cfahr zu stel- lenden Anforderungen erfüllt werden. D, as thicker panes of neodymium glass or panes with a higher neodymium content are relatively expensive, the same effect can also be achieved with less expenditure of neodymium, if one is either matting the glass, for example from the inside, or by moving the glass with an opacifier 'or by both measures, the light path in the glass is extended. In addition, this also ensures that specular reflections of the sodium light caused by any work in the room, e.g. B. when handling bare metal surfaces, could not occur in the same direction. do- get out through the panes, but- scattered on all sides and thereby are distributed inadequately, therefore, invisibly stay cash. The work can now err the space without any disturbances continued «while the darkening to the outside through the Neodymium-containing glass is so effective that everyone to be provided even in the case of direct aviation requirements are met.
