Abstract

The light fitting is constructed in two parts, so that the part (1) supporting the reflector can be pivoted with respect to the fixed housing (2, 2') which accommodates the essential electrical components. As a result, it is also further possible to adjust the light cone on the mounting. It is advantageously possible for the two housing parts (2, 2') to be sealed with respect to one another in a dust and watertight fashion despite the pivotability. <IMAGE>

Description

Die Erfindung betrifft eine Leuchte für Lampen, insbesondere Hochdrucklampen mit einem den Reflektor tragenden Gehäuse.The invention relates to a lamp for lamps, in particular high-pressure lamps with a housing carrying the reflector.

Leuchten für Hochdrucklampen (z.B. Quecksilberdampf-Hochdrucklampen, Halogen-Metalldampflampen usw.) sind kastenförmige Leuchten mit einem innenliegenden Reflektor oder Reflektorleuchten mit außenliegendem Reflektor. Sämtlichen bekannten Leuchten ist gemeinsam, daß eine Verstellung des Reflektors nicht möglich ist, so daß nach Anbringung oder Aufhängung der Lichtkegel nicht mehr in seinem Winkel verändert werden kann. Zum Ändern der Richtung des Lichtkegels muß die gesamte Leuchte geschwenkt werden. Dieses ist wegen der Befestigung nicht möglich.Luminaires for high-pressure lamps (e.g. high-pressure mercury lamps, metal halide lamps etc.) are box-shaped lamps with an internal reflector or reflector lamps with an external reflector. All known lights have in common that an adjustment of the reflector is not possible, so that the angle of the light cone can no longer be changed after attachment or suspension. To change the direction of the light cone, the entire lamp must be swiveled. This is not possible due to the attachment.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Leuchte der eingangs genannten Art zu schaffen, bei der eine einfache Verschwenkung des Lichtkegels möglich ist.The invention is based on the object of creating a luminaire of the type mentioned, in which a simple pivoting of the light cone is possible.

Diese Aufgabe wird grundsätzlich dadurch gelöst, daß ein von dem ortsfesten Gehäuse getrennt ausgebildetes Reflektorgehäuse vorgesehen ist, das um eine im wesentlictien waagerechte Achse schwenkbar ist und daß das ortsf'este Gehäuse zweiteilig, vorzugsweise aus zwei symmetrischen Gehäusehälften bestehend,ausgebildet 'ist, wobei die oberhalb des Reflektors liegenden Abschnitte miteinander räumlich verbunden sind.This object is basically achieved in that a reflector housing is provided which is separate from the stationary housing and which is pivotable about an essentially horizontal axis and that the stationary housing is 'formed' in two parts, preferably consisting of two symmetrical housing halves, the Sections lying above the reflector are spatially connected to one another.

Die erfindungsgemäße Leuchte besteht aus zwei Hauptbauteilen, nämlich dem ortsfesten Gehäuse und dem Reflektorgehäuse. Das Reflektorgehäuse ist derart gegenüber dem ortsfesten Gehäuse schwenkbar, daß der Lichtkegel verstellt werden kann und die einmal eingestellte Lage beibehalten wird.The lamp according to the invention consists of two main components, namely the fixed housing and the reflector housing. The reflector housing is like this pivotable relative to the stationary housing so that the light cone can be adjusted and the position once set is maintained.

Wie in den Unteransprüchen 2 bis 6 angegeben, kann die Leuchte insbesondere so ausgestaltet werden, daß die wesentlichen elektrischen Bauteile neben Fassung und Lampe in dem ortsfesten Gehäuse liegen. Weiterhin ist es möglich, in vorteilhafter Weise das Reflektorgehäuse gegen das ortsfeste Gehäuse wasser-und staubdicht abzudichten.As specified in subclaims 2 to 6, the lamp can be designed in particular so that the essential electrical components are located next to the holder and lamp in the stationary housing. It is also possible to advantageously seal the reflector housing against the stationary housing in a water and dust-tight manner.

Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail below with reference to the drawing using an exemplary embodiment.

Es zeigt:

  • Fig. 1 eine Seitenansicht einer Ausführungsform einer Leuchte nach der Erfindung;
  • Fig. 2 eine teilweise aufgeschnittene Darstellung der Ausführungsform nach Fig. 1; und
  • Fig. 3 eine Einzelheit der Verbindung zwischen Reflektorgehäuse und ortsfestem Gehäuse im vergrößerten Maßstab.
It shows:
  • Figure 1 is a side view of an embodiment of a lamp according to the invention.
  • Fig. 2 is a partially cutaway view of the embodiment of Fig. 1; and
  • Fig. 3 shows a detail of the connection between the reflector housing and the stationary housing on an enlarged scale.

Wie aus der Zeichnung ersichtlich, sind zwei Hauptbauteile, nämlich ein Reflektorgehäuse 1 und ein aus zwei Teilen bestehendes ortsfestes Gehäuse 2, 2' vorgesehen. Das Reflektorgehäuse 1 ist in dem Gehäuse 2, 2' schwenkbar.As can be seen from the drawing, two main components, namely a reflector housing 1 and a stationary housing 2, 2 'consisting of two parts, are provided. The reflector housing 1 is pivotable in the housing 2, 2 '.

Die beiden Gehäusehälften sind einerseits durch rohrförmige Verbindungen 3 und 3' miteinander verbunden, andererseits hat das Gehäuse 2 und 2' (Figur 2( Lager 4 und 4', in denen Zapfen 5 und 5' des Reflektorgehäuses 1 drehbar gelagert sind, so daß das Reflektorgehäuse um diese Lager schwenkbar ist.The two housing halves are connected on the one hand by tubular connections 3 and 3 ', on the other hand, the housing 2 and 2' (Figure 2 (bearings 4 and 4 ', in which pins 5 and 5' of the reflector housing 1 are rotatably mounted, so that the Reflector housing is pivotable about this bearing.

Durch diese Anordnung ist es möglich, trotz fester Montage bzw. Abhängung des Gehäuses 2 und 2' den Reflektor mit dem Reflektorgehäuse 1 zweiseitig in einem Bereich von mindestens 90° zu schwenken und somit den Lichtkegel bzw. die Richtung des Lichtes nach Wunsch einzustellen.This arrangement makes it possible, despite the fixed mounting or suspension of the housing 2 and 2 ', to pivot the reflector with the reflector housing 1 on two sides in a range of at least 90 ° and thus to adjust the light cone or the direction of the light as desired.

Das Reflektorgehäuse 1 enthält neben einem Reflektoreinsatz die Lampenfassung(en) und die Lampe, die Gehäusehälften 2 und 2' dienen zur Aufnahme der elektrischen Bauteile wie Vorschaltgerät, Kondensator, Zündgerät und Anschlußklemmen. Die elektrische Verbindung zwischen den beiden Gehäusehälften erfolgt durchdie rohrförmigen Verbindungen 3 bzw. 3', der elektrische Anschluß der Lampe erfolgt durch die hohl ausgebildeten Zapfen 5 und 5'. Diese Ausführung erlaubt es durch Abdichtungen die Leuchte wasserdicht auszuführen. Hierzu wird die Abschlußscheibe des Reflektorgehäuses 1 sowie die Abschlußdeckel der Gehäuse 2 und 2',wie bei Feuchtraumleuchten üblich, verschlossen. Die Verbindung 3 und 3' wird ebenfalls wasserdicht ausgeführt. Damit das Reflektorgehäuse auch im Bereich der Drehachse wasserdicht abgedichtet werden kann, werden um die Zapfen ringförmigeIn addition to a reflector insert, the reflector housing 1 contains the lamp holder (s) and the lamp, and the housing halves 2 and 2 'serve to accommodate the electrical components such as ballast, capacitor, ignitor and connecting terminals. The electrical connection between the two halves of the housing takes place through the tubular connections 3 and 3 ', the electrical connection of the lamp takes place through the hollow pins 5 and 5'. This version allows the luminaire to be made watertight by means of seals. For this purpose, the end plate of the reflector housing 1 and the end cover of the housings 2 and 2 'are closed, as is customary in damp room lamps. The connection 3 and 3 'is also made watertight. So that the reflector housing can also be sealed watertight in the area of the axis of rotation, rings are formed around the pins

Dichtungen 6 angeordnet, die durch achsialen Anpreßdruck durch die Stirnseite der Lager und 4' unter Druck stehen, sich somit fest anschmiegen und abdichten (Figur 3). Somit lassen sich elektrische Verbindungsleitungen vom Gehäuse 2 in das Reflektorgehäuse 1 bei gleichzeitiger Abdichtung hindurchführen. Gleichzeitig dienen die Dichtungsringe 6 als Reibwiderstand; damit wird das Reflektorgehäuse 1 in der eingestellten Lage gehalten.Seals 6 arranged, which are under axial pressure by the end face of the bearings and 4 'under pressure, thus nestling tightly and sealing (Figure 3). Electrical connecting lines can thus be passed from the housing 2 into the reflector housing 1 with simultaneous sealing. At the same time, the sealing rings 6 serve as frictional resistance; so that the reflector housing 1 is held in the set position.
