Definitions

  • the invention relates to a lighting device comprising a mounting body provided for mounting on an external attachment, for example a ceiling, comprising a lamp body held at an operating position and pivotable back relative to the mounting body with at least one light source attached thereto and / or or with at least one reflector for deflecting the light emitted by the illuminant and for forming a light distribution, comprising a connection unit for electrically contacting and / or controlling the at least one luminous means and comprising a locking module for fixing the luminaire body in the operating position, wherein a pivotally connecting the mounting body provided with the lamp body pivoting module provides an angled formed holding arm and a receiving opening into which the holding arm engages, wherein theintensivesvorric is preferably used as a ceiling light.
  • a lighting device in which a fastening body is mounted on a ceiling or other attachment.
  • a connection unit for a lighting means of the lighting device is provided at the rear.
  • the connection unit is inserted into a recess provided on the ceiling or the other attachment and is thus concealed in the assembled state for a viewer behind the fastening body.
  • a lamp body set At the stationary held mounting body is pivotally a lamp body set.
  • the lamp body can be moved from an operating position into an opening position.
  • a pivoting module is provided which provides an L-shaped holding arm provided on the lamp body and a substantially horizontally extending receiving opening provided on the fastening body for the holding arm.
  • a locking module is provided which defines the pivotable lamp body in the operating position relative to the fastening body.
  • Object of the present invention is to simplify a lighting device with a fixedly mounted mounting body and a pivotally provided in relation to the mounting body lamp body constructive.
  • the assembly, the replacement and the electrical contacting of the at least one provided on the lamp body illuminant are further simplified and inadvertent release of the lamp body are counteracted by the mounting body.
  • the invention in conjunction with the preamble of claim 1, characterized in that the support arm is U-shaped and provides a provided on the mounting body retaining leg, a free leg and the free leg connecting to the holding leg center leg wherein a length h of the free leg is smaller than a width c of the receiving opening provided on the lamp body, and wherein a length b of the center leg is greater than the width c of the receiving opening.
  • the particular advantage of the invention is that due to the U-shaped shape of the support arm and the special geometric dimensions of the pivoting module of the lamp body reliably held on the mounting body and secured against accidental release, especially when spending the same from the open position to the operating position and back ,
  • the support arm is in this case hook-shaped and provided so that in the open position of the free leg of the support arm can be inserted into the receiving opening of the lamp body.
  • a length of the free leg is smaller than a width of the receiving opening. If the lamp body is now pivoted from the open position to the operating position, accidental release is prevented, since a length of the center leg is greater than the width of the receiving opening. It is therefore not possible, due to the geometric dimensions, to remove the hook in the operating position from the receiving opening and to detach the lamp body from the fastening body.
  • the U-shaped holding arm has a channel shape which is closed at the bottom in the mounted state, it is also ensured in the open position that the lamp body can not detach itself from the fastening body as a result of gravity or falls unintentionally to the ground.
  • the free leg of the support arm surrounds the receiving opening at the edge and thus provides protection against unintentional disassembly.
  • the lamp body dominates the fastening body in the operating position at the edge in any case in sections.
  • an edge portion between an outer edge of the pivotally held lamp body and the receiving opening of the pivoting module is smaller than a formed between the free leg of the support arm and a mounting surface of the mounting body Montagestein.
  • the U-shaped holding arm protrudes from the attachment body at the edge.
  • this achieves the result that the luminaire body is moved from a substantially horizontal orientation (operating position) in a substantially vertical orientation (opening position) and that the luminaire body can be inserted in the hook (holding arm) of the pivoting module, without it becoming too Collision between the lamp body and the ceiling or the other attachment comes.
  • the swivel module provides at least two holding arms spaced apart from each other and two receiving openings provided at a corresponding distance therefrom.
  • a stable attachment of the lamp body to the fastening body can be achieved by the provision of at least two retaining arms and two correspondingly arranged receiving openings. An unwanted tilting is thereby prevented.
  • the pivot points formed by a holding arm and the associated receiving opening are preferably located in a common pivot axis of the lighting device.
