Description
Anstrahlleuchte zur Erzeugung abgegrenzter Lichtfelder Die Anstrahlleuchte zur Erzeugung abgegrenzter Lichtfelder nach dein Hauptpatent ermöglicht es, eine beliebige Anzahl scharf abgegrenzter Lichtfelder gleichzeitig zu erzeugen. Zu diesem Zweck besteht die die Lichtaustrittsöffnungen besitzende gewölbte Längswand des Leuchtengehäuses aus einzelnen in den Seitenwänden des Gehäuses verschiebbaren Blendleisten, so daß sowohl durch Entfernen als auch durch Verstellen dieser Blendleisten, die gegebenenfalls noch um eine Längsachse drehbar sein können, an beliebiger Stelle in der Gehäusevorderwand die Bildung und Einstellung von Lichtschlitzen ermöglicht ist, in welche zur Erzeugung abgegrenzter Lichtfelder durch gerichtete Lichtstrahlenbündel an sich bekannte Lamellensätze eingesetzt werden, die gegebenenfalls um parallel zum Lichtschlitz liegende Achsen schwenkbar sind.Floodlight for generating delimited light fields The floodlight to generate delimited light fields according to your main patent makes it possible to use a to generate any number of sharply defined light fields at the same time. To this The purpose is the arched longitudinal wall of the which has the light exit openings Luminaire housing made of individual trim strips that can be slid in the side walls of the housing, so that both by removing and adjusting these trim strips, the can optionally also be rotatable about a longitudinal axis, at any point enables the formation and adjustment of light slits in the front wall of the housing is, in which to generate delimited light fields by directed light beams Per se known lamella sets are used, which may be parallel to axes lying to the light slit can be pivoted.
Die Zusatzerfindung schlägt nun, um diese Leuchte konstruktiv zu vereinfachen und ihre Handhabung, d. h. die Einstellung der Lichtfelder zu erleichtern, vor, die Blendleisten gruppenweise durch Scharniere harmonikaartig miteinander zu verbinden und zwischen diesen die Lamellensätze, die um ihre Längsachsen drehbar sein können, anzuordnen.The additional invention now proposes to simplify this lamp constructively and their handling, d. H. to facilitate the adjustment of the light fields, before, to connect the fascia strips in groups by means of hinges in a harmonica-like manner and between these the sets of lamellas, which can be rotatable about their longitudinal axes, to arrange.
Auf der Zeichnung ist die Anstrahlleuchte nach der Zusatzerfindung in einem Ausführungsbeispiel im Querschnitt dargestellt: In den Seitenwänden i des muldenförmigen Gehäuses der Leuchte sind die Drehzapfen z der Lamellensätze 3, die z. B. aus parallelen oder geneigt zueinander stehenden Blechstreifen bestehen, beiderseits in U-förmigen Rinnen 4 durch Verschieben verstellbar. Zwischen diesen sind die Blendstreifen 5, die gruppenweise durch Scharniere 6 harmonikaartig miteinander verbunden sind, angeordnet.On the drawing is the floodlight according to the additional invention Shown in one embodiment in cross section: In the side walls i des Trough-shaped housing of the lamp are the pivot z of the lamella sets 3, the z. B. consist of parallel or inclined sheet metal strips, both sides adjustable in U-shaped channels 4 by sliding. Between these are the glare strips 5, which are connected in groups by hinges 6 like a harmonica, arranged.
Um bei dieser Leuchte die Lamellensätze 3 einzustellen, ist es nur notwendig, ihre Drehzapfen in den Führungen .4 der Seitenwände i des Leuchtengehäuses durch Verschieben zu verstellen und durch Drehen um die Fühiungszapfen zur Lichtquelle einzurichten. Der Zwischenraum zwischen den einzelnen Blendkammern 3 wird hierbei durch die harmonikaartig miteinander verbundenen Blendstreifen 5 abgedeckt, die sich je nachdem, ob sie mehr oder weniger auseinandergezogen werden, unter einem kleineren oder größeren Winkel zueinander einstellen.To adjust the slat sets 3 on this luminaire, it is only necessary, their pivot pins in the guides .4 of the side walls i of the luminaire housing to be adjusted by moving and by turning around the guide pin to the light source set up. The space between the individual blending chambers 3 is here covered by the harmonica-like interconnected cover strips 5, the depending on whether they are more or less pulled apart, under one Set smaller or larger angles to each other.
