Description

Die Erfindung betrifft eine Leuchte für eine einseitig gesockelte elektrische Lampe, bestehend aus einem eine Fassung und eine Lampe aufnehmenden, wenigstens zweiteiligen Gehäuse und einer daran angeordneten Halterung. In dem Bereich des Gehäuses, der die Lampe überdeckt, ist ein Reflektor vorgesehen; diesem gegenüber ist im Gehäuse eine Aussparung oder lichtdurchlässige Abdeckung vorhanden.The invention relates to a luminaire for an electric lamp with a base on one side, consisting of an at least two-part housing receiving a socket and a lamp and a holder arranged thereon. A reflector is provided in the area of the housing that covers the lamp; In contrast, there is a recess or translucent cover in the housing.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte zu schaffen, deren Lichtaustrittsbereich in verschiedene Richtungen eingestellt werden kann.The invention has for its object to provide a lamp, the light exit area can be adjusted in different directions.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein erstes Gehäuseteil, das die Fassung enthält, und ein zweites Gehäuseteil, das die Lampe überdeckt, und in dem der Reflektor befestigt ist, lösbar miteinander verbunden sind, wobei die Trennebene quer zur Lampenlängsachse verläuft, und die Verbindung derart ausgeführt ist, daß das zweite Gehäuseteil um bestimmte Winkel um die Lampenlängsachse gedreht auf das erste Gehäuseteil aufsteckbar ist.This object is achieved in that a first housing part, which contains the socket, and a second housing part, which covers the lamp, and in which the reflector is fastened, are detachably connected to one another, the parting plane running transversely to the lamp longitudinal axis, and the Connection is designed such that the second housing part can be plugged onto the first housing part rotated by a certain angle about the longitudinal axis of the lamp.

Eine Ausführung einer Verbindung beider Gehäuseteile miteinander besteht darin, daß das eine Gehäuseteil Rasten aufweist, die mit einer oder mehreren Nuten am anderen Gehäuseteil zusammenwirken.One embodiment of a connection of the two housing parts to one another is that the one housing part has catches which interact with one or more grooves on the other housing part.

Durch die Erfindung wird erreicht, daß auf einfache Weise die Ausstrahlrichtung der Leuchte geändert werden kann, beispielsweise um 1800. Es kann damit auf ein zusätzliches, aufwendiges Drehgelenk verzichtet werden.The invention ensures that the direction of emission of the lamp can be changed in a simple manner, for example by 180 ° . It can be on a additional, complex swivel joint can be dispensed with.

Einzelheiten der Erfindung sind im folgenden anhand eines in Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. Es zeigen

  • Figur 1 die Seitenansicht einer erfindungsgemäßen Leuchte
  • Figur 2 einen Querschnitt durch das Leuchtengehäuse nach Figur 1
Details of the invention are explained below with reference to an embodiment shown in the drawings. Show it
  • Figure 1 shows the side view of a lamp according to the invention
  • FIG. 2 shows a cross section through the lamp housing according to FIG. 1

Die in den Figuren dargestellte Leuchte besteht aus einem eine Fassung 1 und eine Lampe 2 aufnehmenden zweiteiligen Gehäuse 3, 4, das über ein Doppelgelenk 5 mit einem Haltearm 6 verbunden ist. In diesem Ausführungsbeispiel ist für die Leuchte eine einseitig gesockelte, im wesentlichen zwei parallele Schenkel aufweisende Kompakt-Leuchtstofflampe 2 vorgesehen. Das zum Betrieb dieser Lampe benötigte Vorschaltgerät (nicht dargestellt) ist außerhalb des Leuchtengehäuses, z.B. im Netzstecker, angeordnet.The lamp shown in the figures consists of a two-part housing 3, 4 receiving a socket 1 and a lamp 2, which is connected to a holding arm 6 via a double joint 5. In this exemplary embodiment, a compact fluorescent lamp 2 with a base on one side and essentially two parallel legs is provided for the lamp. The ballast (not shown) required to operate this lamp is outside the luminaire housing, e.g. arranged in the mains plug.

Die beiden Gehäuseteile 3, 4 sind mittels Rasten 7 und einer Nut 8, die zusammenwirken, lösbar miteinander verbunden. Die Trennebene quer zur Lampenlängsachse ist derart angelegt, daß das erste Gehäuseteil 3 die Fassung 1 aufnimmt, und das zweite Gehäuseteil 4 die Lampe 2 überdeckt.The two housing parts 3, 4 are detachably connected to one another by means of catches 7 and a groove 8 which interact. The parting line transverse to the longitudinal axis of the lamp is designed in such a way that the first housing part 3 receives the holder 1 and the second housing part 4 covers the lamp 2.

In dem die Lampe 2 überdeckenden Gehäuseteil 4 ist ein Reflektor 9 befestigt, der die durch die beiden nebeneinanderliegenden Schenkel gebildete Breitseite 11 der Kompakt-Leuchtstofflampe überspannt und dem gegenüber in der Gehäusewand eine Aussparung vorgesehen ist.In the housing part 4 covering the lamp 2, a reflector 9 is fastened, which spans the broad side 11 of the compact fluorescent lamp formed by the two adjacent legs and to which a recess is provided in the housing wall.

Diese Aussparung kann jedoch auch von einer lichtdurchlässigen und -streuenden Abdeckung 10 verschlossen sein, die entweder fest oder lösbar mit dem Gehäuseteil 4 verbunden ist.However, this recess can also be closed by a translucent and scattering cover 10, which is either fixedly or detachably connected to the housing part 4.

Der Querschnitt des Leuchtengehäuses 3, 4 in der Trennebene ist derart gewählt, daß das zweite Gehäuseteil 4 zumindest um 1800 um die hampenlängsachse gedreht wieder auf das erste Gehäuseteil 3 aufsteckbar ist. In diesem Ausführungsbeispiel ist ein ovaler Querschnitt vorgesehen, der ein Verdrehen der Gehäuseteile 3, 4 gegeneinander um 180° erlaubt. Bei einem Gehäuse mit rundem Querschnitt kann der Verdrehwinkel beliebig gewählt werden.The cross-section of the lamp housing 3, 4 in the separating plane is selected such that the second housing part 4 at least 180 0 around the longitudinal axis hampe rotated back to the first housing part 3 can be fitted. In this embodiment, an oval cross section is provided, which allows the housing parts 3, 4 to be rotated relative to one another by 180 °. In the case of a housing with a round cross section, the angle of rotation can be chosen as desired.
