KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei der farbigen Beleuchtung von Bühnen ist es häufig erforderlich, eine Farbe über eine andere zu bringen und dadurch eine dritte Mischfarbe zu erzeugen, beispielsweise weiß 5. über gelb in rot zu verwandeln. Diese Aufgabe kann nach der den Gegenstand des Hauptpatents 270184 bildenden Einrichtung beispielsweise dadurch gelöst werden, daß man in einem Rahmen Streifen verschiedener Farben in soleher Reihenfolge und Breite anordnet, daß sich der gewünschte Übergang beim Vorbei-. schieben des Rahmens vor dem leuchtenden Feld ergibt. Es ist dann für jeden Farbübergang ein besonders zusammengestelltes Farbfilter erforderlich.In the case of colored lighting of stages, it is often necessary to use one color above bring another and thereby create a third mixed color, for example white 5. Transform over yellow into red. This task can according to the subject matter of the main patent 270184 forming device can be solved, for example, in that one Frame arranges strips of different colors in such order and width that the desired transition when passing. slide the frame in front of the luminous Field results. There is then a specially compiled color filter for each color transition necessary.
Die Aufgabe der vorliegenden Zusatz-Erfindung ist, die Anzahl der Farbfilter zu verringern und doch mit einer ganz geringen Zahl alle überhaupt möglichen Farbübergänge herzustellen. Gelöst wird die Aufgabe dadurch, daß mehrere Systeme von Filterstreifen, von denen jedes für sich einen anderen Farbenübergang ermöglicht, und die Jn Richtung der Lichtstrahlen hintereinander angeordnet sind, unabhängig voneinander verstellt werden. Benutzt man z. B. zwei Filter, deren eines den allmählichen Übergang der Lichtfärbung von weiß nach gelb, deren anderes den Übergang von weiß nach rot gewährt, so kann man durch zweckmäßige Bewegung beider Filter irgendeine Mischung der drei Farben in eine beliebige andere Mischung stetig übergehen lassen, und zwar in einer Weise, die man ebenfalls beliebig wählen kann.The object of the present additional invention is to reduce the number of color filters and yet to produce all possible color transitions with a very small number. The object is achieved in that several systems of filter strips, each of which has a different color transition allows, and the Jn direction of the light rays are arranged one behind the other, independently can be adjusted from each other. If you use z. B. two filters, one of which is the gradual transition of light color from white to yellow, the other of which is the transition from white to red, one can mix the three colors into one by moving the two filters appropriately Let any other mixture go over steadily, in a way that you also can can choose at will.
Die Zeichnung veranschaulicht eine Ausführung der Erfindung, und zwar unter Benutzung eines Farbfilters nach Fig. 3 des Hauptpatents. Vor dem leuchtenden Feld a sind die beiden Rahmen b1 und b2 beweglich so angeordnet, daß die Bewegung des einen senkrecht zu der des anderen erfolgt. Die beiden Rahmen haben Felder e, e von gleicher Farbe und Felder c, d von verschiedener Farbe. Die Rahmen werden wie folgt verwendet : Soll aus der Farbe e über die Farbe c in die Farbe d übergegangen werden, so werden beide Rahmen vor die Lichtquelle so gestellt, daß das gesamte Licht nur durch Felder der Farbe e hindurchgeht, daß also der Rahmen b1 ganz nach oben, der Rahmen b2 ganz nach links gestellt ist. Es wird nun allmählich der Rahmen O1 nach unten geschoben, so lange, bis die gewünschte Stärke der Farbe c vorhanden ist, dann langsam der Rahmen b2 nach rechts bewegt, bis die gewünschte Mischungsfarbe erzielt ist und dann der Rahmen O1 wieder nach oben geschoben. Die Schnelligkeit und die Größe der Rahmenbewegungen bestimmen die Art des Überganges einer Farbe in die andere.The drawing illustrates an embodiment of the invention using a color filter according to FIG. 3 of the main patent. In front of the luminous field a , the two frames b 1 and b 2 are movably arranged so that the movement of one is perpendicular to that of the other. The two frames have fields e, e of the same color and fields c, d of different colors. The frames are used as follows: If you want to change from color e via color c to color d , both frames are placed in front of the light source so that all of the light only passes through fields of color e , so that frame b 1 all the way up, frame b 2 all the way to the left. The frame O 1 is now gradually pushed down until the desired thickness of the color c is present, then the frame b 2 is slowly moved to the right until the desired mixed color is achieved and then the frame O 1 up again pushed. The speed and size of the frame movements determine the type of transition from one color to the other.
Statt des Farbfilters nach Fig. 3 des Hauptpatentes kann auch jedes andere in demInstead of the color filter according to Fig. 3 of the main patent can also be any other in that
Hauptpatent dargestellte Farbfilter benutzt werden. Die Bewegungsrichtungen der Filter brauchen nicht, wie in der Figur dargestellt, senkrecht aufeinander zu stehen, sondern können beliebige Winkel bilden.Color filters shown in the main patent are used. The directions of movement of the filters do not need to be perpendicular to one another, as shown in the figure, but can form any angle.
Es wird noch bemerkt, daß es an sich bekannt ist, mehrere Farbfilter von verschiedener Farbe vor einer Lichtquelle derartig unabhängig voneinander beweglich anzuordnen, daß ihre wirksame Fläche verändert werden kann.It should also be noted that it is known per se to use several color filters of various types To arrange color in front of a light source so that it can be moved independently of one another, that their effective area can be changed.
