Description

  

      1'Vechselzeichenanor        dnung.       Wechselzeichensysteme, z. B. mit Wech  selzahlen dienen dazu, mit einem     Blend-          system    oder dergleichen, die Zahlen 0-9  darzustellen. Durch     Aneinanderreihen    von  solchen Blendsystemen können beliebig     viel-          stellige    Zahlen dargestellt werden.  



  Bei den bekannten Einrichtungen befin  den sich auf einer Grundplatte Glühlampen.  Über die Grundplatte wird ein     Blendsystem     gestülpt, das erstens für die einzelnen Lam  pen Kammern enthält, so dass sich die  Glühlampen nicht gegenseitig überstrahlen  können, und das zweitens oben     Ausschnitte     trägt, durch die das Licht austreten kann.  Aus diesen leuchtenden Strecken setzen sich  die einzelnen Zeichen zusammen, wenn die  einem bestimmten Zeichen entsprechenden  Glühlampen eingeschaltet werden.  



  Der Erfindung liegt die bekannte Tat  sache zu Grunde, dass zum     Beispiel    bei einem  Glasstab das an einem Ende eintretende  Licht unter     gewissen    Bedingungen (Total  reflexion) nicht seitlich austritt, sondern im    Glasstab weitergeleitet wird und erst am  andern Ende wieder austritt. Die Anwen  dung dieses     Prinzipes    für Wechselzeichen er  möglicht ein Weglassen der Blenden, die  freie Wahl des Platzes, an dem die einzelnen  Lampen befestigt werden sollen, das Um  leiten des     Lichtes    um Ecken und eine  derartige Ausbildung und Zusammenfassung  der     Stabenden,    dass formschöne und klare  Zahlen- oder Zeichenbilder entstehen.  



  Die     Wechselzeichenanardnung    gemäss der  Erfindung zeichnet sich dadurch aus, dass  das Licht von Lichtquellen wenigstens zum  Teil und     unter    Ausnützung der Total  reflexion durch einen jeder Lichtquelle zu  geordneten Körper so hindurchgeleitet wird,  dass die aus diesem     Körper    austretenden  Lichtstrahlen ein Zeichenbild ergeben, wobei  durch Einschalten     bestimmter    Gruppen von       Lichtquellen    verschiedene Zeichen dargestellt  werden können.  



  In der beiliegenden Zeichnung ist die  Anordnung beispielsweise für fünf Leucht-      strecken einer Wechselzahl     dargestellt    und  nachstehend beschrieben.  



  Das Licht der Lampe 1 tritt beim Stab  ende 2 in den Glaskörper ein. Es wird inner  halb desselben     fortgeleitet    und tritt an der  Fläche 3 aus. Dadurch entsteht ein be  leuchtetes Zeichenelement von der Form der  Fläche 3. Ein analoger Vorgang findet statt,  wenn die Lampen 4, 7, 10 oder 13 brennen.  Durch Einschalten bestimmter Lampen  gruppen können     bestimmte    Leuchtzeichen  dargestellt werden, da die Flächen 3, 6, 9,  12 und 15 in einer Ebene liegen und in be  stimmter Lage zueinander angeordnet sind.

    So entsteht beispielsweise durch Einschalten  der Lampengruppe 1, 4, 7, 10 und 18 das       Leuchtbild    der Zahl     "4",        de,    die     Leucht-          strecken    3, 6, 9, 12 und 15     beleuchtet    wer  den. Durch Einschalten der     Lampengruppe    1    und 4 wird die Zahl "1" gebildet, die sich  aus den Leuchtstrecken 3 und 6 zusammen  setzt.



      1 'alternating character arrangement. Variable character systems, e.g. B. with Wech sel numbers are used to display the numbers 0-9 with a blend system or the like. By lining up such blend systems, any number of digits can be displayed.



  In the known devices are located on a base plate incandescent lamps. A blend system is placed over the base plate, which firstly contains chambers for the individual lamps so that the light bulbs cannot outshine each other, and secondly it has cutouts at the top through which the light can exit. The individual signs are composed of these luminous lines when the light bulbs corresponding to a certain sign are switched on.



  The invention is based on the known fact that in the case of a glass rod, for example, the light entering at one end does not exit laterally under certain conditions (total reflection), but is passed on in the glass rod and only exits at the other end. The application of this principle for alternating characters makes it possible to omit the aperture, the free choice of the place where the individual lamps are to be attached, the redirection of the light around corners and such a training and summary of the rod ends that elegant and clear numbers - or drawing images arise.



  The alternating sign arrangement according to the invention is characterized in that the light from light sources is at least partially passed through a body assigned to each light source using total reflection so that the light rays emerging from this body result in a sign image, with certain ones being switched on Groups of light sources different characters can be represented.



  In the accompanying drawing, the arrangement is shown, for example, for five light paths with an alternating number and described below.



  The light from the lamp 1 occurs at the rod end 2 in the glass body. It is forwarded within the same and exits at surface 3. This creates an illuminated sign element with the shape of the surface 3. An analogous process takes place when the lamps 4, 7, 10 or 13 are on. By turning on certain groups of lamps, certain luminous characters can be displayed, since the surfaces 3, 6, 9, 12 and 15 lie in one plane and are arranged in certain positions to each other.

    For example, when the lamp groups 1, 4, 7, 10 and 18 are switched on, the luminous image of the number "4", de, and the luminous paths 3, 6, 9, 12 and 15 are illuminated. By switching on the lamp groups 1 and 4, the number "1" is formed, which is made up of the lighting paths 3 and 6.
