Abstract
Description
Die Erfindung bezieht sich auf elektronische Röh renblitzgeräte, vornehmlich für den Einsatz bei der Unterwasserfotografie. The invention relates to electronic tubes flash units, primarily for use with underwater photography.
Die naturgegebene Filterwirkung des Wassers führt in Abhängigkeit der Entfernung des Blitzgerätes und der Kamera vom jeweiligen Motiv bzw. Objekt beim Arbeiten unter Wasser und in Verbindung mit der jeweiligen Farbtemperatur des verwendeten Films zu Farbverfälschungen.The natural filter effect of the water leads depending on the distance of the flash and the camera of the respective subject or object when working under water and in connection with the respective color temperature of the film used to color falsifications.
Es sind an den Blitzgeräten also Mittel und Maß nahmen vorzusehen, die diese dadurch universeller verwendbar machen, daß sich verschiedene Farb temperaturstufen auswählen lassen, wodurch bei der Unterwasserfotografie, je nach Objektentfernung der Rotanteil des Blitzes beeinflußt werden kann.So there are means and dimensions on the flash units took care to make this more universal make usable that different colors Let temperature levels be selected, which means that the Underwater photography, depending on the object distance Red component of the flash can be influenced.
Die generelle Lösung der zuvor beschriebenen Auf gabenstellung ist im Patentanspruch 1 wiederge geben; die Unteransprüche beinhalten vorteilhafte Einzelteile bzw. Detailweiterbildungen der tech nischen Lehre des Hauptanspruchs, die weitest gehend schematisch zudem in den zugehörigen Zeich nungen dargestellt und anhand dieser im einzelnen anschließend noch näher beschrieben sind.The general solution to the previously described position is again in claim 1 give; the sub-claims contain advantageous Individual parts or further developments of the tech niche teaching of the main claim, the broadest also schematically in the associated drawing shown and based on these in detail are subsequently described in more detail.
Es zeigen:Show it:
Fig. 1 die schematische Vorderansicht auf ein erfindungsgemäßes Blitzgerät und Fig. 1 is a schematic front view of a flash device according to the invention and
Fig. 2 eine Seitenansicht zu Fig. 1. FIG. 2 shows a side view of FIG. 1.
Das dargestellte Blitzgerät besteht in seinem Grund aufbau aus dem mit einem Traggriff 6 versehenen Ge häuse 1 für die Aufnahme der den Blitz steuernden Bauteile und einem der Blitzröhre 3 zugeordneten Reflektor 2.The flash unit shown consists in its basic structure of the housing provided with a carrying handle 6 Ge 1 for receiving the components controlling the flash and a reflector 2 assigned to the flash tube 3 .
Zur Lösung der mit vorliegender Erfindung gestell
ten Aufgabe zeichnet es sich aus durch die Anord
nung von mindestens zwei Blitzröhren 3 und 4 unter
schiedlicher Farbtemperatur im Reflektor 2, Zuord
nung elektrischer bzw. elektronischer Umschalt
elemente im, und entsprechende Wahlschalter 5 am
Gehäuse 1. Verwendet man hier also beispielsweise
eine unkorrigierte und eine durch entsprechende Ein
färbung des Glases farbkorrigierte Röhre, so lassen
sich für das Blitzen damit bereits drei verschie
dene Bereiche schalten, nämlich:
Röhre I (Pos. 3)
Röhre II (Pos. 4) sowie
Röhren I + II.To solve the problem with the present invention, it is characterized by the arrangement of at least two flash tubes 3 and 4 with different color temperature in the reflector 2 , assignment of electrical or electronic switching elements in, and corresponding selector switch 5 on the housing 1 . If, for example, one uses an uncorrected tube and a tube corrected by appropriate coloring of the glass, three different areas can be switched for flashing, namely:
Tube I (item 3)
Tube II (item 4) as well
Tubes I + II.
Beim Arbeiten mit dem zuvor beschriebenen Gerät ist es somit möglich, Farbverfälschungen, die aus un terschiedlichen Objektentfernungen durch die Filter wirkung des Wassers entstehen, durch eine entsprechen de Auswahl bzw. Zusammenschaltung der einzelnen Blitzröhren auszugleichen.When working with the device described above it is thus possible to color falsifications resulting from un different object distances through the filters effect of water arise through a corresponding de Selection or interconnection of the individual Balance flash tubes.
In weiterer vorteilhafter Ausgestaltung des erfin derischen Grundgedankens ist letztlich noch vorge sehen, daß die einzelnen Röhren 3 und 4 in dersel ben Reflektorebene "E" liegen, wobei diese Röhren 3 und 4 kreisrund, u-förmig o.ä. ausgebildet sein kön nen und konzentrisch bzw. symmetrisch zueinander und/oder zur Reflektormitte "M" liegen sollten. In a further advantageous embodiment of the inventive principle, it is ultimately also seen that the individual tubes 3 and 4 are located in the same reflector plane "E" , these tubes 3 and 4 being circular, U-shaped or the like. can be formed and should be concentric or symmetrical to each other and / or to the center of the reflector "M" .
In den Rahmen der vorliegenden Erfindung fallen ne ben der zuvor beschriebenen Ausführung gleicher maßen auch solche Geräte, bei denen anstelle einer einzigen Reflektor-/Röhreneinheit mehrere nebenein ander angeordnete Reflektoren mit Einzel- oder eben falls Mehr-Röhrenbestückung, Verwendung finden.Within the scope of the present invention ne ben the same execution as described above also measure those devices where instead of one single reflector / tube unit several next to each other other arranged reflectors with single or flat if multi-tube equipment is used.
