Description

Elektrische Entladungslampe oder Leuchtröhre mit einer Füllung aus Edelgasen und Quecksilber und einer durch die Quecksilberstrahlung angeregten Luminophorschicht Zusatz zum Patent 699 o96 Die Erfindung ist eine weitere Ausgestaltung der im Zusatzpatent 699 o96 beschriebenen elektrischen Entladungslampe oder Leuchtröhre. Nach diesem $atent ist der durch die Quecksilberstrahlung der Entladungslampe oder Leuchtröhre angeregten Luminophorschicht aus mit Mangan aktiviertem Cadmiumphosphat zur Erhöhung der Lichtausbeute Cadmiumchlorid zugesetzt, so daß ein Cadmiumchlorphosphat entsteht. Mit diesem rötlichen Leuchtstoff wird in Verbindung mit der sichtbaren Strahlung ein weißliches Mischlicht von warmem, also rotstichigem Farbton erzielt. Es wurde festgestellt, daß mit dem Leuchtstoff des Zusatzpatents 699o96 ein dem natürlichen Tageslicht ungemein nahekommendes Mischlicht erzielt werden kann, wenn dem mit Mangan aktivierten Cadmiumchlorphosphat Magnesium- und/oder Zinkwolframat in einer zur Herstellung gleicher Lichtstromanteile des Phosphats und Wolframats ausreichenden Mengen zugesetzt ist. Dabei ist nicht nur der Farbeindruck, sondern auch diu, spektrale Energieverteilung weitgehend dem Tageslicht angeglichen, etwa wie bei den bekannten Leuchtröhren mit Kohlensäurefüllung. Diesen gegenüber unterscheidet sich naturgemäß eine Entladungslampe oder Leuchtröhre mit dem erfindungsgemäßen Leuchtstoffgemisch durch die wesentlich höhere Lichtausbeute, die den Lichtausbeuters der einzelnen Leuchtstoffbestandteilenicht nachsteht.Electric discharge lamp or fluorescent tube with a filling Noble gases and mercury and a luminophore layer excited by the mercury radiation Addendum to patent 699,096 The invention is a further embodiment of the additional patent 699 o96 described electric discharge lamp or fluorescent tube. After this The atent is that caused by the mercury radiation of the discharge lamp or fluorescent tube stimulated luminophore layer made of cadmium phosphate activated with manganese to increase added cadmium chloride to the light output, so that a cadmium chlorophosphate is formed. This reddish phosphor is used in conjunction with the visible radiation a whitish mixed light of warm, i.e. reddish hue is achieved. It was found that with the fluorescent substance of addendum patent 699o96 one of the natural Mixed light that comes very close to daylight can be achieved if that with manganese activated cadmium chlorophosphate magnesium and / or zinc tungstate in one for Production of the same luminous flux proportions of the phosphate and tungstate is sufficient Amounts is added. Not only is the color impression, but also diu, spectral Energy distribution largely adapted to daylight, similar to the known ones Light tubes with carbon dioxide filling. This differs from this themselves naturally a discharge lamp or fluorescent tube with the phosphor mixture according to the invention by the much higher light output, which the light exploiter of the individual Phosphor components are not inferior.

Die gute tageslichtähnliche Mischfarbe wird nicht beeinträchtigt, wenn dem mit Mangan aktivierten Cadmiumchlorphosphat zwecks Erhöhung der Nachleuchtdauer Vanadium, z. B. in Form von Vanadiumpentoxyd, zugesetzt wird, wie schon in einem anderen Zusatzpatent zu Patent 699o96, nämlich Patent 697 395, beschrieben ist.The good daylight-like mixed color is not impaired, if the cadmium chlorophosphate activated with manganese to increase the afterglow time Vanadium, e.g. B. in the form of vanadium pentoxide is added, as in one Another additional patent to patent 699o96, namely patent 697 395, is described.

Wenn es erforderlich ist, die Leuchtröhre nach Anbringung der Leuchtstoffschicht zu biegen, so ist es zweckmäßig, das Cadmiumchlorphosphat zum Teil durch Zinkberylliumsilicat zu ersetzen, das durch einen Gehalt von 1,5 bis 3010 Mangan rötlich luminesziert. Durch diesen teilweisen Ersatz des Cadmiumchlorphosphats wird dessen Lösungsfähigkeit im erweichten Glas stark herabgesetzt, während anderseits die Mischlichtfarbe nicht wesentlich verändert wird, vorausgesetzt, daß der Zinkberylliumsilicatanteil den Phosphatanteil nicht erreicht oder übertrifft.If it is necessary to bend the arc tube after the phosphor layer has been applied, it is advisable to replace some of the cadmium chlorophosphate with zinc beryllium silicate, which has a reddish luminescence due to its content of 1.5 to 3010 manganese. This partial replacement of the cadmium chlorophosphate greatly reduces its solubility in the softened glass, while on the other hand the mixed light color is not significantly changed, provided that the zinc beryllium silicate content does not equal or exceed the phosphate content.
