Definitions

  • the invention relates to a fastening device for a lamp, in particular a ceiling-mounted lamp, with an elastic support arm, which surrounds a mounting portion of the lamp in a mounting position and which is elastically deformable for the purpose of assembly in a deformation main direction.
  • a support rail or other attachment is from the EP 2 409 077 A1 a fastening device with an elastically deformable support arm is known, which is elastically deformed for the purpose of assembly in a deformation main direction and surrounds the same at least in sections after insertion of the lamp.
  • two opposite elastic retaining arms are bent apart and that a housing of the lamp is positioned between the arms.
  • On the housing a with respect to its contour of the geometry of the support arms adapted mounting portion is formed. In this respect, an at least partially planar contact of the holding arms results in the housing of the lamp in the mounting position.
  • the insertion of the lamp in the fastening device is easy and fast.
  • the lamp can be removed in a simple manner from the mounting device.
  • Object of the present invention is to provide a fastening device for a lamp in such a way that the lamp is secured against unintentional removal from the mounting device.
  • the invention in conjunction with the preamble of claim 1, characterized in that at least one elastic support arm is provided which is applied in the mounting position of the support arm to the lamp so that a deformation of the support arm is blocked in the deformation main direction, and which is elastically deformable in a deformation auxiliary direction for the purpose of mounting.
  • the particular advantage of the invention is that an elastic deformation of the support arms in the mounting position is not possible in a simple manner. As a result, the lamp can not be removed from the fixing device. Rather, the elastic deformation of the support arms is blocked by the provision of the also elastically deformable support arms.
  • the support arms is insofar as a backup function. They lie in the mounting position to a support portion of the lamp and counteract the elastic deformation of the support arms in the main deformation direction.
  • the abutment of the support arms to the support section is self-holding.
  • the self-retaining attachment is designed such that the support arms are pressed by the weight of the lamp or an elastic restoring force of the retaining arms to the support portion.
  • this further improves the definition of the luminaire in the fastening device.
  • a contact region of the support arms may be shaped and adapted to the geometry of the support portion of the lamp that forms a self-locking in the contact zone.
  • the support arm is integrally formed on the support arm or protrudes from the support arm.
  • the effect of the determination is improved depending on the specific geometric conditions, since the deformation of the support arm in the deformation main direction and the deformation of the support arm in the deformation auxiliary direction are not carried out independently when molding the support arm to the support arm. By the dependence between the deformation movements, in particular an unintentional removal of the lamp from the fastening device can be counteracted.
  • the support arms are deformed in the deformation auxiliary to solve the blockage of the elastic deformation of the support arms and to allow the removal of the lamp from the mounting device.
  • the support arms are lifted by the elastic deformation of the same of the support portion of the lamp.
  • it therefore requires at least two-stage conscious operation of the fastening device for removing the lamp.
  • the support arm is elastically deformed in the deformation auxiliary direction to release the blockage of the support arms.
  • the holding arms are elastically deformed in the deformation main direction and the lamp is removed from the fastening device.
  • the retaining arms and the support arms are provided in the mounting position in a recess provided on the lamp.

  • the fastening device can be concealed by the provision of the recess on the lamp. The visual appearance of the lamp is not affected.
  • the recess provides protection against accidental operation of the fastening device. Rather, a conscious engagement in the recess is required to elastically deform the support arm against the deformation aid and to dissolve the blockage of the support arm.
  • the fastening device is formed symmetrically with respect to a longitudinal central axis.
  • the assembly is simplified by the provision of symmetry. A wrong assembly is prevented in this respect.
  • a lamp 1 after Fig. 1 is determined by two fastening devices 2 according to the invention to an attachment, not shown, in particular a ceiling.
