Description

  

      Abblendevorrichtung.       Die Erfindung betrifft eine Abblende  vorrichtung, z. B. für die Abblendung von  Scheinwerfern sowie von     Glühlampen    und  andern Lichtquellen. Besonders zweckmässig  ist dieselbe für die Abblendung von Schein  werfern an Autos, Velos,     Eisenbahnen,    Stra  ssenbahnen     etc.     



  Die     Abblendevorrichtung    zeichnet sich  erfindungsgemäss dadurch aus, dass sie eine  zusammenschiebbare Blende aufweist, durch  deren Verstellung die Farbe des durch  die     Abblendevorrichtung    hindurchgelassenen  Lichtes verändert wird.  



  In der     Zeichnung    ist beispielsweise eine  Ausführungsform der erfindungsgemässen       Abblendevorrichtung    dargestellt.  



  Die     Fig.    I und     II    zeigen einen Schein  werfer mit der     Abblendevorrichtung    in zwei  verschiedenen Stellungen.     Fig.        III    zeigt  schematisch die     Abblendevorrichtung    selbst  in seitlichem Schnitt. Die     Abblendevorrich-          tung    nach den     Fig.    I bis     III    besteht aus  einer Glasscheibe<I>a,</I> deren Zentrum<I>b</I> farbig  abgetönt, z. B. blau oder gelb gefärbt ist.    Als zusammenschiebbare Blende ist eine Iris  blende c bekannter Art mit     undurchsichtigen     Lamellen vorhanden.

   In     Fig.    I ist die Iris  blende in geöffnetem Zustande dargestellt.  Das Licht der Lampe d dringt durch die  Ringzone e ungehindert ins Freie. Die Farbe  des     durchgelassenen    Lichtstromes ist über  wiegend weiss, weil durch die zentrale Par  tie nur ein geringer Anteil des gesamten  Lichtes hindurchgeht. Die     Fig.        II    zeigt die       Irisblende    in geschlossener Stellung, so dass  die ganze Ringzone abgedeckt ist und nur  das farbige Zentrum frei ist, das einer Öff  nung der Blende gegenübersteht. Das in     die-          ser-Stellung    durch die     Abblendevorrichtung     hindurchgehende Licht ist also farbig.

   Man  kann diese Vorrichtung zum Beispiel für  Verdunkelungsgebrauch bei einem Auto- oder       Veloscheinwerfer    verwenden, indem die Iris  blende nach Belieben     augenblicklich    auf  volles Licht. oder Abblendung gestellt wer  den     kann.    Dies kann zum Beispiel durch       fernmechanische    Übertragung vom Führer  sitz aus     bewirkt    werden. In     Fig.    IH ist die           Irisblende    ebenfalls geschlossen. Es muss  nicht notwendigerweise eine     Irisblende    vor  handen sein, es könnte auch eine andere zu  sammenschiebbare Blende, z. B. aus Stoff.  verwendet werden.

   Ferner könnte davon ab  gesehen werden, eine in der Mitte     gefärbte.     durchscheinende Scheibe zu verwenden; es  könnten vielmehr die Lamellen einer Iris  blende aus durchscheinendem, farbigem Ma  terial bestehen, z. B. aus gelb oder blau ge  färbtem Zelluloid,     Zellon        etc.    Eine gefärbte  Zone könnte auch exzentrisch auf der Glas  scheibe angebracht sein bei entsprechender       Ausbildung    der Blende, das heisst,     dass    die  Öffnung der geschlossenen Blende exzen  trisch ist.



      Dimming device. The invention relates to a masking device, for. B. for dimming headlights as well as light bulbs and other light sources. It is particularly useful for dimming headlights on cars, bicycles, trains, trams, etc.



  According to the invention, the screening device is characterized in that it has a collapsible screen, the adjustment of which changes the color of the light that is let through the screening device.



  In the drawing, for example, an embodiment of the screen device according to the invention is shown.



  Figs. I and II show a headlamp with the dimming device in two different positions. Fig. III shows schematically the masking device itself in a lateral section. The screening device according to FIGS. I to III consists of a pane of glass <I> a </I> whose center <I> b </I> is tinted in color, e.g. B. is colored blue or yellow. As a collapsible diaphragm there is an iris diaphragm c of a known type with opaque lamellas.

   In Fig. I the iris is shown in the open state. The light from lamp d penetrates unhindered through the ring zone e. The color of the luminous flux that passes through is predominantly white because only a small proportion of the total light passes through the central part. Fig. II shows the iris diaphragm in the closed position, so that the entire ring zone is covered and only the colored center is free, which faces an opening of the diaphragm. The light passing through the masking device in this position is therefore colored.

   This device can be used, for example, for blackout use in a car or bicycle headlight, by turning the iris to full light instantly at will. or dimming can be set. This can be effected, for example, by remote mechanical transmission from the driver's seat. In Fig. IH the iris diaphragm is also closed. It does not necessarily have to be an iris diaphragm, it could also be another diaphragm that can be pushed together, e.g. B. made of fabric. be used.

   Furthermore, a colored one in the middle could be disregarded. to use translucent disk; it could rather be the lamellae of an iris diaphragm made of translucent, colored Ma material, z. B. from yellow or blue colored celluloid, celluloid, etc. A colored zone could also be eccentrically attached to the glass disc with a corresponding design of the aperture, that is, the opening of the closed aperture is eccentric.
