Description

Edelgasgefüllte elektrische Quecksilberdampfröhre oder -lampe mit Luminophorschicht Zusatz zuin Patent 671677 Gegenstand des Hauptpatents 671 677 ist eine elektrische Quecksilberdampfröhre oder -lampe mit Edelgasgrundfüllung, Glühelektroden oder kalten Blechelektroden sowie einer im Gefäßinnern oder auf der Gefäßwand oder auf einem der Röhre vorangestellten Schirm angebrachten Luminophorschicht, die dadurch gekennzeichnet ist, daß die Luminophorschicht aus einer isomorphen Mischung eines Zinkberylliumsilicates, und zwar zweckmäßig im Molekularverhältnis i Be0 : i Zn0 : i Si02, besteht, das durch einen Zusatz von Mangan in Mengen von o, i bis 5 %, vorzugsweise o, 5 bis 2,o o/o, aktiviert ist. Derartige Zink-Berylliumsilicat-Luminophorschichten zeichnen sich durch sehr hohe Lichtausbeute aus, wobei man es in der Hand hat, je nach dem prozentualen Anteil an Mangan Farbtöne zu erhalten, die in Mischung mit dem blaugrauen Licht der Quecksilberröhre zwischen Grün und Orange liegen. Bei einem Zn0 # Be0 # Si02-Luminophor mit einem Mangangehalt von 1,2 bis 2% erhält man gelblichweiße bis rötlichweiße Farbtöne. Es sind dies also farbstickige Farbtöne von weißlichem Aussehen. Ein weißliches Licht mit einem glühlampenähnlichen, also einem stark rotstickigen Farbton erhält man schließlich dadurch, daß man dem Zn0 # Be0 # Si02-Luminophor noch einen gewissen Prozentsatz eines mit Mangan aktivierten Cadmiumsilicatluminophors hinzufügt. Obwohl es hierbei also möglich ist, eine große Reihe verschiedener weißlicher Farbtöne zu Es hat sich nun herausgestellt, daß bei den in dem Hauptpatent beschriebenen elektrischen Quecksiiberdampfröhren oder -lampen mit zugeordneter Luminophorschicht solche rein weißen Farbtöne erhalten werden können, wenn dem zur Herstellung der Luminophorschicht verwendeten, mit Mangan aktivierten isomorphen Zink-Berylliumsilicat-Gemisch erfindungsgemäß 5 bis 2o o;`o eines blau leuchtenden Wolframatluminophors beigemischt sind. Der Wolframatluminophor wird hierbei vorteilhaft einer isomorphen Mischung eines Calciumbleiwolframatluminophors gebildet, dessen Anteil an Bleiwolframat zweckmäßig zwischen q. bis 70;`o beträgt.Electric mercury vapor tube or lamp filled with noble gas with a luminophore layer Addition to patent 671 677 The subject of the main patent 671 677 is an electric mercury vapor tube or lamp with a noble gas base filling, glow electrodes or cold sheet metal electrodes as well as a luminophore layer attached to the inside of the vessel or on the vessel wall or on a screen placed in front of the tube, which is characterized in that the luminophore layer consists of an isomorphic mixture of a zinc beryllium silicate, suitably in the molecular ratio i Be0: i Zn0: i Si02, which by adding manganese in amounts of 0.1 to 5%, preferably 0.1 5 to 2, oo / o, is activated. Such zinc beryllium silicate luminophore layers are characterized by a very high light yield, whereby it is in the hand, depending on the percentage of manganese, to obtain color tones which, when mixed with the blue-gray light of the mercury tube, lie between green and orange. With a Zn0 # Be0 # Si02 luminophore with a manganese content of 1.2 to 2%, yellowish-white to reddish-white shades are obtained. So these are colored shades with a whitish appearance. A whitish light with an incandescent lamp-like, i.e. a strongly red-sticky hue, is finally obtained by adding a certain percentage of a cadmium silicate luminophore activated with manganese to the Zn0 # Be0 # Si02 luminophore. So although it is possible to use a wide variety of whitish hues It has now been found that in the electric mercury vapor tubes or lamps with an associated luminophore layer described in the main patent, such pure white shades can be obtained if the manganese-activated isomorphic zinc-beryllium silicate mixture used to produce the luminophore layer according to the invention is 5 to 20 o; `o of a blue glowing tungstate luminophore are added. The tungstate luminophore is advantageously formed from an isomorphic mixture of a calcium lead tungstate luminophore, the proportion of lead tungstate of which is advantageously between q. to 70; `o.
