Description

Vielfach bestehen Langfeldleuchten für Leuchtstofflampen aus einem die Vorschaltgeräte, Fassungen und Leuchtstofflampen tragenden Oberteil und einem die Blendung herabsetzenden, durchscheinenden Unterteil.In many cases, linear luminaires for fluorescent lamps consist of one the ballasts, sockets and fluorescent lamps and a top part the glare-reducing, translucent lower part.

Die Erfindung betrifft Langfeldleuchten mit einem rinnenförmigen Oberteil aus mehreren zueinander im Winkel stehenden, parallel zur Leuchtenachse verlaufenden Längsflächen und mit einer dicht am Oberteil anliegenden, lichtdurchlässigen Abdeckwanne.The invention relates to linear luminaires with a channel-shaped upper part from several at an angle to each other, running parallel to the luminaire axis Longitudinal surfaces and with a translucent cover that fits tightly against the upper part.

Der Oberteil wird dabei am zweckmäßigsten und billigsten auf einer Abkantmaschine hergestellt. Die Abdeckwanne, die meist aus organischem Glas, wie Polyacrylsäureester, hergestellt ist, muß so geformt sein, daß nach Möglichkeit eine Abdichtung gegenüber dem Oberteil sichergestellt ist. Bisher hat man die Abdeckwanne mit besonderen Stirnwänden versehen, die so geformt waren, daß diese Staubabdichtung erreicht wurde.The top is the most convenient and cheapest on one Bending machine manufactured. The cover pan, which is mostly made of organic glass, like Polyacrylic acid ester, must be shaped so that if possible a seal against the upper part is ensured. So far you have the cover provided with special end walls, which were shaped so that this dust seal was achieved.

Die Erfindung zeigt nun einen Weg, wie die Abdichtung bei Leuchten mit derartigem rinnenförmigem Oberteil ohne Verwendung weiterer Teile durch eine besondere Formgebung einer aus einem Stück bestehenden Abdeckwanne erreicht werden kann.The invention now shows a way of how to seal lights with such a channel-shaped upper part without the use of other parts by a special shape of a one-piece cover pan can be achieved can.

Erfindungsgemäß wird eine aus einem Stück bestehende, annähernd kahnförmige Abdeckwanne verwendet, deren Stirnflächen gegenüber dem Querschnittsprofil des rinnenförmigen Wannenmittelteils hochgezogen und entsprechend dem Querschnitt des Oberteils geformt sind.According to the invention, a one-piece, approximately boat-shaped Cover pan used, the end faces of which compared to the cross-sectional profile of the channel-shaped Trough middle part pulled up and shaped according to the cross section of the upper part are.

In der Zeichnung ist in Abb. z die Leuchte nach der Erfindung im Längsschnitt dargestellt; Abb. a zeigt einen Querschnitt.In the drawing, Fig. Z shows the lamp according to the invention in longitudinal section shown; Fig. A shows a cross section.

d ist der Leuchtenoberteil, der mit seinen in der ganzen Länge der Leuchte durchgehenden Kanten b auf der Abkantpresse hergestellt wurde. c ist die aus organischem Glas in einem Stück gezogene Abdeckwanne, deren etwa kahnförmige Gestalt aus der perspektivischen Ansicht der Abb. 3 hervorgeht. Charakteristisch für diese Form sind die gegenüber dem Wannenmittelteil hochgezogenen Stirnflächen d der Abdeckwanne, die harmonisch verlaufend in die Seitenwände des Mittelteils übergehen und, wie aus Abb. a ersichtlich, dem Querschnitt des Oberteils angepaßt sind. Die Ränder des Wannenmittelteils e, denen gegenüber die Stirnflächen d hochgezogen sind, sind in der Abb. i unterhalb des Oberteils a schwach angedeutet.d is the upper part of the luminaire, with its entire length the Luminaire continuous edges b was made on the press brake. c is the One-piece cover made of organic glass, the roughly punt-shaped Shape from the perspective view of Fig. 3 emerges. Characteristic for this shape are the end faces that are raised in relation to the central part of the tub d the cover pan, which runs harmoniously into the side walls of the middle section and, as can be seen from Fig. a, adapted to the cross-section of the upper part are. The edges of the central part of the tub e, opposite which the end faces d are drawn up are indicated weakly in Fig. i below the upper part a.

Der Rand der Stirnflächen d kommt so beim Anpressen der Abdeckwanne an den Oberteil a gleichzeitig mit dem Rand des Mittelteils e zur Anlage an den Oberteil a.The edge of the end faces d comes out when the cover pan is pressed against it to the upper part a at the same time with the edge of the middle part e to rest on the Top a.
