Definitions

  • the present invention relates to a mounting arrangement for mounting a luminaire member to a luminaire holder.

  • the inventive arrangement is provided with a plurality of advantages. Involving two mounting members, the mounting process is divided into readily achievable steps, wherein a first step is represented by mounting a first mounting member to the luminaire holder, facilitated by the limited size and low weight of the first mounting member. A further step is given by combining a luminaire member to the first mounting member by means of the second mounting member, effectively mounting a luminaire member to the luminaire holder - aided by the inventive mounting arrangement. Obviously the fitting of a first mounting member to a luminaire holder can be handled by a single worker, obviating the support of a bulky luminaire.
  • the first mounting member is formed to accommodate attaching means to attach the first mounting member to a luminaire holder.
  • attaching means can be easily accommodated by arranging expedient openings, slots, channels or other guiding means in the respective first mounting member.
  • the first mounting member comprises attaching means to attach the first mounting member to a luminaire holder.
  • attaching means to attach the first mounting member to a luminaire holder.
  • hook-like assemblies might be formed to combine with elements of a suspended ceiling, or clamping means might be arranged.
  • the accommodation means are preferably arranged to form a snap-fitting or latching connection with the luminaire member. This creates the possibility to provide accommodation for the luminaire member in a swift and efficient manner, advantageously without the usage of tools, contributing to reduced efforts and costs.
  • the mounting arrangement is provided with the possibility to be moved with respect to the luminaire member, even while accommodating the luminaire member, and for example also while the luminaire member is latched or snap-fittingly combined to the mounting arrangement. This could be achieved for example by a combination, limiting movement preferably in one direction of restriction, whereas clearance for movement is provided advantageously in the plane normal to the direction of restriction.
  • one of the mounting members comprises accommodation faces for accommodating the luminaire member form-fittingly, preferably obviating unnecessary limitations concerning the movement of the luminaire member with respect to the mounting arrangement.
  • a slight margin remains in at least one direction, to provide the possibility to adapt the position of the luminaire member with respect to the mounting arrangement.
  • one of the mounting members comprises snap-fitting or latching means, formed to combine snap-fittingly the first mounting member with the second mounting member.
  • the usage of tools can be obviated while combining the second mounting member to the first mounting member. Accordingly, the possibility to support the luminaire member two handed, while mounting the luminaire member to the luminaire holder emerges. Thus, a significant improvement in the mounting of luminaires is achieved, saving costs and efforts.
  • one of the snap-fitting or latching means comprises a plurality of snap-fitting or latching positions, enhancing opportunity for various modifications in the spatial relation of luminaire member and luminaire holder.
  • An alteration of the spatial relation for example can be gained by the choice of one of the plurality of snap-fitting or latching positions.

And further with providing a set of latching positions the possibility is raised to exhibit a predefined alteration procedure, adapting a complex lighting system to a variety of luminaire holders.
  • one of the snap-fitting or latching means is arranged to lock the snap-fitting or latching means in one of the plurality of snap-fitting or latching positions. Fostering the possibility to adapt to various luminaire holders, a reliable spatial relation of luminaire member and luminaire holder is achieved.
  • one of the snap-fitting or latching means combining the first mounting member with the second mounting member is formed at least in part as a thread or winding.
  • a thread or winding provides a continuous set of latching positions for combining the first and the second mounting member, implicating all the benefits of a plurality of latching positions and further providing a very precise range of adjustment.
  • the mounting arrangement can be adapted to various luminaire members and even to a variety of lamp holders providing a versatile use.
  • one of the snap-fitting or latching means for combining the first mounting member with the second mounting member is arranged to perform a rotation with respect to the corresponding other snap-fitting or latching means, advantageously while being in a fitted state.
  • said snap-fitting or latching means are arranged to lock by the rotation and unlock by a reversed rotation, facilitating the save and defined arrangement of the luminaire member with respect to the luminaire holder.
  • one of the mounting members favorably the second mounting member, comprises a plurality of members.
  • one of the mounting members comprises advantageously a first assembly member and a second assembly member, formed to combine snap-fittingly.
  • the first and second assembly members are arranged rotatable with respect to each other while being snap-fittingly combined. This raises opportunity to suppress rotational movement of the luminaire member with respect to the corresponding mounting member, while at the same time a comprised assembly member is provided with the possibility to be rotated.
  • the rotatable assembly member is combined to the latching or snap-fitting means of the corresponding mounting member and advantageously contributes to locking the combination.
