Definitions

  • the invention relates to a luminaire with a pivotable and releasably mounted lighthead.
  • Such a luminaire is known from the prior art, for example in the form of a recessed ceiling luminaire.
  • the light head of the luminaire is suitable for receiving a light source and is pivotably and / or rotatably mounted on a holding element or mounting ring. By a rotation or pivoting of the light head relative to the holding element, the direction of the light output of the lamp can be changed.
  • the light head and the retaining element are firmly connected to each other.
  • the complete luminaire, ie the light head and the retaining element must be replaced or the light head must be dismantled at least laboriously by detaching a plurality of separate fastening means (eg screws, nuts, washers, etc.).
  • the invention has for its object to provide a correspondingly improved light.
  • the luminaire is intended to enable simple replacement of the light head, that is to say without removal of the retaining element or costly disassembly.
  • the invention relates to a luminaire, comprising a light head for receiving a light source, and a holding element, wherein the light head is arranged by means of a pivot bearing about a pivot axis pivotally mounted on the holding element.
  • the inventive lamp is characterized in that the pivot bearing has a first connecting part on the holding element and a second connecting part on the light head. At least one of the connecting parts has a first latching element pretensioned in the direction of the pivoting axis towards the other connecting part.
  • the first latching element cooperates with a corresponding second latching element of the other connecting part - ie at least by its bias - in such a way (non-positively) to the Lighthead and the support member in a mounting direction substantially transversely to the pivot axis releasably and to connect pivotally about the pivot axis.
  • the invention has the particular advantage that due to the bias acting substantially perpendicular to the mounting direction - ie non-positive connection - a mounting and dismounting of the light head is easily and quickly executed. For this purpose, only the light head is to be guided relative to the holding element in the mounting direction. For disassembly, for example, only a manual pulling force is required, which exceeds the bias of the first locking element. Light head and retaining element are thus provided in a modular manner in a simple manner. By providing the pivot bearing by means of a simple frictional connection by bias also the structure of the pivot bearing can be simplified as a whole. In addition, separate fastening means can be dispensed with, since the light (dis) assembly as well as for storage serving biasing function is provided integrated in the pivot bearing.

  • a user may manually pivot the lighthead 1 about the pivot axis X6 (and possibly further rotate about the vertical axis) to adjust the orientation of the light output. Due to the bias, the first connecting parts 8 exert on the second connecting parts 10 holding forces in the direction of the pivot axis X6, so that a pivotable holding or latching connection is provided. Preferably, by means of spring forces, the lighthead 1 is snap-latched to the holding element 2.
  • Several portions of the lamp 100, and the light head 1 and the support member 2 may be designed to be conductive, for example. Of metallic materials to conduct an electric current through the support member 2 and the light head 1 to the light source.
  • each latching part 16 is preferably pressed against the upper edge of the recess 18 shown here. Due to its spherical shape, the force acts obliquely on the ball 16, so that a portion of the force results in the direction of the pivot axis X6, as symbolized by the arrow 16.4.
  • the latching part, or each latching part, of the first latching element may be arranged on the light head and the corresponding recess, or the respective recess, of the second latching element may be provided in the holding element.
  • the pivot bearing of this alternative embodiment is formed inversely with respect to the embodiment shown.
  • the luminaire 100 could have only a single first connecting part 8 and a single second connecting part 10.
  • the light fixture 100 may include a conventional rotatable bearing relative to this releasable pivot bearing 6 to produce a secure bilateral pivotal connection about the pivot axis X6.
  • the present invention is not limited to the above-described embodiment, as far as it is encompassed by the subject of the following claims. In particular, all features of the embodiment may be provided and combined in any number and number. Incidentally, in addition to the luminaire 100, the present invention is also directed independently to a correspondingly configured light head 1 and a correspondingly configured holding element 2.

Abstract

La présente invention concerne une lampe (100) qui possède une tête lumineuse (1) destinée à accueillir une source de lumière, et un élément de maintien (2). La tête lumineuse (1) est disposée sur l'élément de maintien (2), montée au moyen d'un palier de pivotement (6) de manière à pouvoir pivoter autour d'un axe de pivotement (X6). Le palier de pivotement (6) possède une première pièce de liaison (8) au niveau de l'élément de maintien (2) et une deuxième pièce de liaison (10) au niveau de la tête lumineuse (1). Au moins l'une des pièces de liaison (8, 10) possède un premier élément d'encliquetage (12), précontraint vers l'autre pièce de liaison (10, 8) quand vu dans la direction de l'axe de pivotement (X6), lequel coopère avec un deuxième élément d'encliquetage (14) correspondant de l'autre pièce de liaison (10, 8) de manière à relier la tête lumineuse (1) et l'élément de maintien (2), dans une direction de montage (Z2) sensiblement transversale à l'axe de pivotement (X6), de manière amovible et pivotante autour de l'axe de pivotement (X6).
