Definitions

  • the invention relates to a luminaire node for the electrical and mechanical connection of at least one light source socket and a screen surrounding the light source with a lamp holder, with a central holding part with a bore for receiving the lamp holder and at least one tubular connector arranged fixedly on the holding part for each light source holder is and on the connecting piece, a mounting part for the screen that can be pushed onto it is rotatably axially fixed, to which a tubular extension of the screen can be attached.
  • the invention also relates to a lamp with such a lamp node and a method for mounting the lamp.
  • Luminaire nodes of this type are known from the publications US-A-2 491 448 and US-A-2 850 622. They represent a load-bearing basic element of luminaires to which the light source socket and the lampshade and the lamp holder are attached on the one hand and which should at the same time allow electrical cabling of the light source sockets in accordance with the safety regulations, which is particularly problematic in the case of adjustable lamp shades.
  • the luminaire body must be mechanically stable without significantly increasing the weight of the luminaires.
  • the known luminaire nodes partially meet these requirements, but only by using a large number of intricately shaped individual parts, of which in particular load-bearing parts appear to the outside and determine the appearance of the luminaire. This means that the right parts for each type of luminaire must be manufactured and kept in stock. A change in the external appearance of the luminaire therefore requires a new luminaire node that has been specially adapted to it.
  • the final assembly of the parts of the lamp which determine the external appearance should preferably be simple.
  • this object is achieved by the features according to the characterization of claim 1. With this configuration, it is possible to separate the luminaire node, which essentially has a functional meaning, which is the same for many luminaire types, from the external appearance of the luminaires.
  • FIGS. 3 and 4 show the lamp node 1 in the preassembled state, its essential individual parts, namely a central holding part 2 and a fastening part 3 for a lampshade, being shown in more detail in FIGS. 3 and 4.
  • the central holding part has a bore 5 for receiving a light carrier 6 (FIG. 1) and for introducing the electrical connecting line 7.
  • a transverse bore 8 serves to receive a tubular connecting piece 9 on one or both sides, which can be firmly fixed therein by means of a screw 10.
  • the already mentioned fastening part 3 is pushed onto the connecting piece 9, in which the electrical connection line to the lampholder 11 (schematically) is guided and rotatably mounted.
  • the fastening part 3 is intended to hold the lampshade 14 (indicated). This can be pushed from the lamp holder side over the fastening part 3 and fastened to it with screws in the corresponding threaded holes 15.
  • the lampshade together with the fastening part can be freely rotated around the connecting piece, the connecting piece 9 with the light socket 11 and the holding part 2 remaining stationary and therefore no torsion acting on the connecting line 7.
  • the central holding part 2 and the fastening part 3, as can be seen in FIGS. 3 and 4, are designed as profile pieces from the same profile. They are preferably sections of a drawn aluminum profile with a corresponding cross section, which are subsequently provided with the corresponding bores.
  • the profile has longitudinal ribs 16 with channels 17 lying between them, which allow air circulation along the ribs and thus in particular reduce the heating of the parts which can be touched from the outside.
  • Lateral guides 18 are provided instead of channels, which are provided on the fastening part 3 for receiving corresponding projections of the lampshade 14.
  • the longitudinal ribs 16 are shaped on the periphery so that they can be written into a circle, so that the tubular extension of the screen 14 on the fastening part 3 and a tubular cover sleeve 19 can be pushed over it on the holding part 2 and are supported by the longitudinal ribs 16.
  • the lamp node 1 can be preassembled from a mechanical and electrical point of view, as shown in FIG. 2, for example, and that the outwardly appearing parts, such as lampshade 14, cover sleeve 19 and lamp holder 6, are retrofitted can be (Fig. 1).
  • the outwardly appearing parts such as lampshade 14, cover sleeve 19 and lamp holder 6, are retrofitted can be (Fig. 1).
  • the final assembly can take place as follows: First, the cover sleeve 19, which is secured with a spring 20, is pushed over the central holding part 3. However, since the electrical connection line 7 has already been installed, the connection line must first be drawn into the cover sleeve 19 and its opening for the light carrier 6. To push the cover sleeve onto the holding part 2, the line is temporarily inserted into the lower channel 17. If the cover sleeve is pushed on, the connecting line 7 can be drawn into the light holder 6 and this can be attached to the central holding part 2. After that, only the lampshade 14 has to be pushed over the fastening part 3 and fixed thereon. If only one lamp is provided, as shown in FIG. 1, a cover plate 21 can be arranged on the opposite side of the central fastening part 2.
  • the lamp node described can be preassembled in the form shown in FIG. 2, after which the final assembly, as mentioned, requires only a few manipulations.
  • the electrical connection line can already be connected before final assembly, which is also advantageous for reasons of safety.
  • the lampshade can also be freely rotated without affecting the connection cable.
  • luminaires of different external shapes can be constructed in a simple manner with the luminaire node parts described, e.g. B. in one-lamp (Fig. 1) or two-lamp variant, with different light sources, such as for stand lamps, table lamps or ceiling lamps, with different shades, and in different colors.
  • the same luminaire nodes of the type described can be used and preassembled for all variants.
