Description
Bei Verwendung der neuzeitlichen Leuchtstofflampenhat sich gezeigt, daB eine Abblendung zur Schonung der Augen testwendig ist.When using modern fluorescent lamps it has been shown that dimming is necessary to protect the eyes.
Derartige Abblend'vorrichtungen bestehen entweder aus einzelnen Blenden, die, zu einem Längskörper zusammengesetzt, die Sicht auf die nackten Lampen auf einen bestimmten Winkel beschränken, oder aber aus Rasterblenden, die, in der Leuchtchöffnung angebracht, dieselbe Aufgabe erfüllen.Such screening devices either consist of individual screens, which, put together to form a longitudinal body, open up the view of the naked lamps Restrict a certain angle, or from grid screens that, in the Leuchtchloch appropriate to perform the same task.
Bei der vorliegenden, in den Ansprüchen gekennzeichneten Erfindung handelt'es sich um eine Abblendvorrichtung der zuerst genannten Art.In the present invention characterized in the claims It is a dimming device of the first mentioned type.
In den Abb. i his 4 ist eine beispielsweise Ausführung ,des Erfindungsgedankens dargestellt. Abb. i zeigt die Draufsicht in Richtung auf die Abblendvorrichtung; Abb. 2 zeigt den Schnitt durch die Abblendvorrichtung parallel zur Lichtachse; Abb.3 ist eine perspektivische Ansicht eines Einzelteils der Abblendvorrichtung, die, zu der Gesamtvorrichtung zusammengesetzt, das perspektivische Bild ergibt, wie es in Abb.4 gezeigt ist.In the Fig. I to 4 is an example of an embodiment of the inventive concept shown. Fig. I shows the plan view in the direction of the masking device; Fig. 2 shows the section through the dimming device parallel to the light axis; Fig 3 is a perspective view of a component part of the masking device, the, put together to form the overall device, the perspective image results in how it is shown in Fig.4.
Um .die Leuchtstofflampe a, die in üblicher Weise in der Fassung b angeordnet ist, ist die etwa aus einem durchscheinenden Kunststoff hergestellte Abblendvorrichtung aus mehreren Einzelblenden c angeordnet, die parallel zur Achse e angeordnete Lamellen d besitzt, so daB der ungehinderte Lichtaustritt senkrecht zur Achse auf den Winkel ,B beschränkt ist.To .the fluorescent lamp a, which is in the usual way in the socket b is arranged, which is made approximately from a translucent plastic Dimming device arranged from several individual diaphragms c, which are parallel to the axis e has lamellas d arranged so that the unimpeded light exit is perpendicular to the axis to the angle, B is limited.
Die Einzelabblendvorrichtungen c sind mit ihren senkrecht zur Lichtachse angeordneten, den Lichtaustritt parallel zur Achse auf den Winkel a beschränkenden Lamellen auf zwei Rundstangen f aufgereiht und durch die an beiden Enden der Rundstangen aufgeschraubten Muttern g. zusammengehalten.The individual dimming devices c are perpendicular to the light axis arranged, limiting the light exit parallel to the axis to the angle a Lamellae are lined up on two round bars f and through those at both ends of the round bars screwed nuts g. held together.
:Mittels zweier in den Löchern h angebrachten Federn i, die die Leuchtstoff lampe a umfassen, wird die ganze Abblendvorrichtung an der Leuchtstofflampe.a befestigt, wobei zwei Nocken k, die auf den einzelnen Abblendvorrichtungen angeordnet sind, einen Abstand von der Leuchtstofflampe verbürgen.: By means of two springs i placed in the holes h, which form the fluorescent material include lamp a, the entire dimming device is attached to the fluorescent lamp. where two cams k, which are arranged on the individual dimming devices, guarantee a distance from the fluorescent lamp.
Die einzelnen Lamellen d können noch mit Zapfen i (Abb. 3) versehen sein, die bei der Zusammensetzung der ganzen Abblendvorrichtung in entsprechende Löcher m der benachbarten Abblendvorrichtung eingreifen und so der ganzen Vorrichturg Halt gegen Verdrehen geben.The individual lamellas d can also be provided with pegs i (Fig. 3) be appropriate in the composition of the whole masking device Engage holes m of the neighboring dimming device and so the whole device Give hold against twisting.
