Bei der Leuchte nach der Erfindung ist an den stirnseitigen Enden der Lampenabdeckung, d.h. an den Kopfstücken, je ein Verbindungselement befestigt, über das die Lampenabdeckung mit dem an der Decke, an der Wand oder an einem besonderen Träger befestigten Grundkörper verbunden ist. Wenn die Lampenabdeckung zum Auswechseln der Lampe gelöst ist, wird sie um die Verbindungselemente abgeschwenkt und bleibt parallel zu dem Grundkörper an diesem hängen. Ein Halten durch den Monteur ist dann nicht mehr erforderlich. Dieser hat beide Hände frei, um die Lampe auszuwechseln. Dadurch, daß die Verbindungselemente entsprechend gestaltet sind, bewegen sie sich beim Wiederbefestigen der Lampenabdeckung in ihre Ausgangslage zurück, d.h. sie gelangen nicht zwischen die Dichtflächen, sondern sie nehmen ihre Ausgangsoder Ruhelage wieder ein. Anders ausgedrückt, die Verbindungselemente bewegen sich selbsttätig in ihre vorbestimmte Stellung zurück. Diese kann, je nach Konstruktion der Leuchte, innerhalb oder außerhalb des Grundkörpers bzw. der Fassungsgehäuse liegen.In the lamp according to the invention is on the front Ends of the lamp cover, i.e. on the head pieces, one each Fastened fastener over which the lamp cover with that on the ceiling, on the wall or on a special one Carrier fastened base body is connected. If the Lamp cover for replacing the lamp is loosened it swings around the connecting elements and remains hang parallel to the body. A hold by the fitter is then no longer necessary. This has both hands free to replace the lamp. Thereby, that the connecting elements are designed accordingly, move when refitting the lamp cover back to their starting position, i.e. they don't get between the sealing surfaces but they take their starting or Rest position again. In other words, the fasteners move automatically into their predetermined Position back. Depending on the construction of the Luminaire, inside or outside the body or the Socket housing.
In vorteilhafter Weise sind die Verbindungselemente als federnde Bügel, insbesondere aus Kunststoff, ausgebildet, so daß sie sich durch die den Bügeln innewohnende Federkraft bei der Wiederbefestigung der Lampenabdeckung an dem Fassungsgehäuse in ihre Ausgangslage zurückbewegen, ohne die Befestigung zu behindern.Advantageously, the connecting elements are as resilient bracket, in particular made of plastic, so that it is due to the spring force inherent in the brackets when reattaching the lamp cover to the Move the socket housing back to its original position without to hinder the attachment.
Es sind auch andere Formen von Verbindungselementen, wie beispielsweise Scharniere oder dergleichen, denkbar.There are other forms of fasteners, such as for example hinges or the like.
Der Monteur, der beispielsweise auf einer Leiter steht, kann sich auf die wesentlichen Arbeiten konzentrieren. Hierbei hängt die Lampenabdeckung an den Verbindungselementen, wenn die Lampenabdeckung zum Auswechseln einer Lampe gelöst ist. Am Ende der Montagearbeiten schwenkt der Monteur die Lampenabdeckung parallel zu dem Grundkörper zurück und befestigt dieses in der Ausgangslage, wobei sich die Verbindungselemente selbsttätig in ihre Ruhelage zurückbewegen.The fitter, who is standing on a ladder, for example, can concentrate on the essential work. The lamp cover hangs on the connecting elements, when the lamp cover to replace a lamp is solved. At the end of the assembly work, the fitter swings the lamp cover parallel to the base body and fastened this in the starting position, whereby the Move the fasteners back to their rest position automatically.
