Description

Bei Verwendung von Leuchtröhren bei der Raumbeleuchtung ist die Lichtausstrahlung nach der Raumdecke nicht überall erwünscht. Die Helligkeitsabstufung innerhalb von Räumen wirkt angenehm gegenüber der eintönigen Vollausleuchtung.When using fluorescent tubes for room lighting, the light emission is not desirable everywhere after the ceiling. The brightness gradation within Rooms appear pleasant compared to the monotonous full illumination.

Der in der Erfindung vorgeschlageneLichtschirm kann an jeder Leuchtröhre leicht aufgesetzt werden. Er besteht aus plastischem geformtem Folienstoff und kann lichtdurchlässig sein, so daß die Raumlichtfarbe moduliert werden kann. Er kann andererseits lichtdicht sein und inwendig einen Überzug für die Reflexion des Lichtes aufweisen.The light screen proposed in the invention can be attached to any fluorescent tube easily put on. It consists of plastic molded film material and can be translucent so that the room light color can be modulated. He can on the other hand, be light-tight and internally a coating for the reflection of the light exhibit.

In der Zeichnung ist eine beispielsweise Ausführungsform nach der Erfindung dargestellt. Auf die beiden Enden der Leuchtröhre i werden Bügel aus Polyäcrylsäureester oder sonstigem geeigneten Werkstoff federnd aufgesetzt. Der Federbügel 2 besitzt beim Ausführungsbeispiel zwei gegeneinandergerichtete Druckflansche 3, 3', welche die Leuchtröhre umfassen. Außerdem sind am Federbügel zwei Stifte 5, 5' angeordnet, welche das ebenfalls federnd aufgesetzte halbzylindermantelförmige Lichtschirmblatt ¢ festhalten. Sonach kann der Lichtschirm q. stets rasch und leicht zwecks Reinigung abgenommen werden.In the drawing is an example embodiment according to Invention shown. Brackets made of polyacrylic acid ester are placed on both ends of the fluorescent tube i or any other suitable material applied resiliently. The spring clip 2 has in the embodiment two oppositely directed pressure flanges 3, 3 ', which include the fluorescent tube. In addition, two pins 5, 5 'are arranged on the spring clip, which also resiliently attached semicylindrical jacket-shaped light screen sheet ¢ hold tight. The light screen q. always quick and easy for cleaning be removed.

Statt halb kann der Lichtschirm die Röhre ganz umfassen. Er kann farbige Aufdrucke aufweisen oder, wenn er lichtdicht ist, Aussparungen zeigen.Instead of half, the light screen can completely encompass the tube. He can be colored Have imprints or, if it is light-tight, show recesses.

Der Lichtschirm kann auch aus Metallfolie bestehen. Die lösbare Befestigung kann auf mannigfache Weise erfolgen.The light screen can also consist of metal foil. The detachable attachment can be done in a variety of ways.
