Definitions

  • the present invention relates to a recessed ceiling light with a support frame, in particular from a one-piece casting, e.g. made of cast aluminum, and various lighting parts and installation elements to be attached to this support frame, the support frame having an upper part and a lower part with annular contact surfaces for installation in a ceiling opening, and the upper part and lower part being connected to one another by two arms. These arms generally have cutouts which can accommodate suitable fastening means for attaching the support frame in the ceiling opening.
  • the upper part of the support frame is closed on the ceiling side.
  • reflector brackets, lamp holders and connections protruding into the interior of the lamp are attached.
  • other installation elements such as ballasts, terminals or the like are usually attached to the outside of the upper part or to the outside of one of the arms.
  • the support frame is a one-piece cast aluminum part, the attachment of the aforementioned lighting parts to the support frame is difficult.
  • grains had to be carried out in the cast part so that the bores required for fastening the individual lamp parts could then be made in several work steps, a different number of bores being required at different locations depending on the lamp type. So far, it has not been sensible to rationalize the manufacturing and assembly process by providing different support frames for different types of luminaires from the outset, since the support frames are cast and this would involve considerable tool costs.
  • the difficulty was the relatively complex mechanical processing of the cast support frame.
  • the present invention is therefore based on the object to provide a recessed ceiling light of the type mentioned, in which the support frame is suitable for differently designed luminaire types and complex machining operations on the support frame in connection with the attachment of the luminaire parts to be attached can be omitted.
  • the upper part of the support frame has approximately the shape of a truncated cone shell or a cylinder shell with an approximately circular opening which is open on the ceiling side.
  • This shape has the advantage that an equipment rack can be inserted into the support frame from above.
  • This device carrier can be a sheet metal part, on which the various lighting parts such as ballasts, connecting terminals, etc. can then be attached.
  • differently shaped device carriers or device carriers can be used, which are equipped with different lamp parts.
  • the mechanical processing of the device carrier is much easier since it is a sheet metal part. It is sufficient according to the invention that only one variant is produced from the supporting frame made of cast iron.
  • the attachment of the device carrier to the support frame is preferably carried out in that the support frame has radially inwardly facing cast-on tabs that can accommodate fasteners for attaching the device carrier.
  • the recessed ceiling light has a supporting frame 1, which is preferably made from a one-piece aluminum casting and comprises a truncated cone jacket 2, two arms 3 and an annular system 4 for a ceiling opening.
  • a horizontal ceiling mounting ring 5 is formed, which rests on the ceiling after the luminaire has been installed in the ceiling of a room.
  • the arms 3 connect the truncated cone jacket 2 to the annular abutment 4, comprising a section which is the same Includes the angle of inclination to the axis of rotation of the truncated cone shell 2, as well as a section adjoining it in the direction of the annular contact 4, which section runs parallel to the axis of rotation.
  • the parallel section of the arms 3 has cutouts 7 which can be used for fastening the support frame 1 in a ceiling by means of suitable fastening elements.
  • the parallel section of the arms 3 is preferably provided on its outside with a sawtooth profiling 6 in order to ensure a secure connection of the support frame 1 to the fastening elements (see FIG. 3).
  • annular shoulder 8 for receiving the support ring 10 of the reflector 9 is excluded (see FIGS. 1 and 4). Furthermore, three fastening tabs 11 with threaded bores 12 are formed on the side of the support frame 1 opposite the ceiling mounting ring 5, at the rear edge inside the truncated cone 2 (FIG. 2).
  • FIG. 3 the installation of a device carrier 13 for a compact fluorescent lamp is shown.
  • the device carrier 13 is formed from a piece of sheet metal and has a circular plate 14 which covers the upper opening of the truncated cone shell 2.
  • the clips 15 are attached on opposite sides in the edge area of the circular plate 14 and protrude through the truncated cone jacket 2.
  • the clips 15 comprise a lower, straight or only slightly inclined section in the direction of the jacket, an adjoining section bent in the direction of the truncated cone axis and an upper section Section that steps back towards the coat.
  • the section of the clasps 15 running in the direction of the truncated cone axis forms resilient catches 16, behind which an annular retaining bead 17 can snap in, which is formed at the rear end of the reflector 9 which can be inserted into the supporting frame 1.
  • the support ring 10 fits snugly in the annular shoulder 8 of the ceiling mounting ring, so that the reflector 9 cannot move further into the support frame 1.
  • the support ring 10 and the annular shoulder 8 have approximately the same thickness in order to ensure a pleasant external appearance of the recessed ceiling light.
  • a lamp holder 18 is mounted on the inside of the circular plate 14, the feed lines 19 of which are led out of the interior of the truncated cone shell 2 through a recess 20 in the truncated cone shell 2 (FIG. 3).
  • the device carrier 13 has a section likewise formed from the same sheet metal, which together with one of the arms 3 forms a housing-like receptacle 21 for ballast elements 22 mounted thereon.
  • the feed lines 19 can be passed on from the ballast elements 22 to the outside, in the region of the ballast elements 22, on the connection terminals 23 mounted on the device carrier 13.
  • the device carrier 13 is connected to the supporting frame 1 only by means of the screws engaging in the three fastening tabs 11 and can be selected and quickly replaced depending on the type of lamp used.
  • FIG. 5a shows an equipment carrier 24 which is suitable for metal halide lamps, high-pressure metal-halide lamps and high-pressure sodium-vapor lamps.
  • the equipment carrier 24 also has a circular plate plate 14, on the inside of which a lamp holder 25 and clips 15 are attached.
  • a connecting plug 26 to the supply unit is attached to the device carrier 24.
  • FIG. 5b shows a device carrier 27 which is suitable for low-voltage halogen lamps.
  • a lamp holder 28 and clips 15 are fastened to the inside of the circular plate 14 of the device carrier 27.
  • the device carrier 27 has a connection terminal 29.
