Elektronenblitzgerät mit einer InduktionsspuleElectronic flash unit with an induction coil

Die Erfindung bezieht sich auf ein Elektronenblitzgerät mit einer Elektronenblitzröhre, einem Gehäuse für die Elektronenblitzröhre mit einem Reflektor, einem zur Speisung der Elektronenblitzröhre dienenden Speicherkondensator und einer zwischen dem Speicherkondensator und der Elektronenblitzröhre angeschlossenen Induktionsspule.The invention relates to an electronic flash device with an electronic flash tube, a housing for the electronic flash tube with a reflector , a storage capacitor serving to feed the electronic flash tube and an induction coil connected between the storage capacitor and the electronic flash tube.

i Derartige Elektronenblitzgeräte sind ganz allgemein bekannt ^ und erfreuen sich insbesondere bei Fotografen immer wachsender Beliebtheit. Trotz verschiedener Anstrengungen, diese Geräte durch Miniaturisierung leichter handhabbar zu machen, blieben sie bisher doch relativ groß, weil ihre Bestandteile einen beträchtlichen Platzbedarf haben, beispielsweise die Induktionsspule, die üblicherweise zur Vergleichmäßigung des Blitzes in dem Entladungsstromkreis zwischen dem Speicher- ■ kondensator und der Elektronenblitzröhre liegt-.Such electronic flash units are generally known ^ and are enjoying growing popularity, especially with photographers. Despite various efforts, this To make devices easier to handle through miniaturization, they have so far remained relatively large because of their components take up a considerable amount of space, for example the induction coil, which is usually used to smooth out the Lightning in the discharge circuit between the storage capacitor and the electronic flash tube.

ORIGINAL INSPECTEDORIGINAL INSPECTED

Der Erfindung liegt nun die Aufgabe zugrunde,, ein Elektronenblitzgerät mit Induktionsspule.der eingangs genannten Art. dahingehend zu verbessern, daß der Platzbedarf für die Induktionsspule erheblich verringert wird.The invention is based on the object, an electronic flash device with induction coil of the type mentioned at the beginning. to the effect that the space required for the induction coil is significantly reduced.

Dies wird erfindungsgemäß dadurch erreicht, daß die Induktionsspule auf wenigstens eine Oberfläche des Gehäuses gewickelt 1st.This is achieved according to the invention in that the induction coil wound on at least one surface of the housing.

Nach Ausgestaltungen der Erfindung ist die Induktionsspule um die Außenfläche des Gehäuses herum oder auf einer Innenfläche des Gehäuses aufgewickelt.According to embodiments of the invention, the induction coil is around the outer surface of the housing or on an inner surface of the housing wound.

Im folgenden wird die Erfindung anhand zweier in der beigefügten Zeichnung dargestellter Ausführungsbeispiele näher erläutert. Es zeigen:In the following, the invention will be described in more detail with reference to two exemplary embodiments shown in the accompanying drawing explained. Show it:

Pig.4 stellt eine andere Ausführungsform der Erfindung dar,in der die Induktivitätsspule 7 um den Reflektor 601 der Blitzlichtschaltung gewickelt ist.Diese Anordnung hat den Vorteil,daß sie die Dichte des Stromes durch die Blitzlicht-röhre herabsetzt und den Raumbedarf für die Blitzlichtschaltung herbsetzt,indem der anderenfalls vergeudete Platz "'jm den Reflektor herum ausgenutzt wird.Der Draht 604 ist mit dem positiven Anschluß des Kondensators 5 verbunden und um den Reflektor 601 zur Ausbildung der Spule 7 gewickelt,und das andere Ende des Drahtes ist dann mit der positiven Elektrode 603 der Röhre 3 verbunden. Um weiterhin den Platzbedarf herabzusetzen oder aus anderen Fabrikationsgründen kann die Induktionsspule 7 auf eine oder mehrere Flächen des Blitzlichtghäuses und/oder der Blitzlichtabdeckung gewickelt werden.Eine derartige Anordnung ist in Fig.5 dargestellt,wo der die Spule bildende Draht 604 auf die Innenfläche des Blitsliclitgehäuses 704 aufgewickelt ist.Ein Ende des Drahtes 604 ist mit dem positiven Anschluß 702 des Kondensators 5 verbunden,während das andere Ende des Drahtes 604 mit dem positiven Anschluß 703 der Blitzlichtröhre verbunden ist.Pig. 4 shows another embodiment of the invention in which the inductance coil 7 is wound around the reflector 601 of the flashlight circuit. This arrangement has the advantage that it reduces the density of the current through the flashlight tube and reduces the space required for the flashlight circuit by using the otherwise wasted space "'jm the reflector around exploited wird.Der wire 604 is connected to the positive terminal of the capacitor 5 is connected and wound around the reflector 601 to form the coil 7, and the other end of the wire is then connected to the positive Electrode 603 of the tube 3. To further reduce the space requirement or for other manufacturing reasons, the induction coil 7 can be wound on one or more surfaces of the flashlight housing and / or the flashlight cover Wire 604 is wound onto the inner surface of the lightning bolt housing 704. One end of the wire s 604 is connected to the positive terminal 702 of the capacitor 5 , while the other end of the wire 604 is connected to the positive terminal 703 of the flash tube.

Weitere Ausführungsformen der Erfindung stellen Verbesserungen gegenüber den schon beschriebenen dar,indem sie nur den Bur Abgabe des gewünschten Lichtblitzes erforderlichen Betrag an elektrischer Energie benötigen und dadurch eine erhebliche Energieersparnis mit sich bringen und die Zyklus-Further embodiments of the invention represent improvements over those already described by only the Required for the delivery of the desired flash of light Amount of electrical energy and thus bring considerable energy savings with it and the cycle
