Definitions

  • a lighting device for fluorescent lamps of the strip type comprising a sheet metal sole supporting lamp accessories such as a starter, ballast choke and at least one pair of base supports fixed to the two ends of the sole.
  • the sole is covered by a cover retained in the two base supports made of insulating material and separated from the sole by distance beads in these base supports.
  • the invention aims to avoid these drawbacks. It is characterized in that at least one elastic distance element is inserted in the slot between the sole and the hood at least in the immediate vicinity of the ballast choke.
  • the elastic distance element is preferably made of metal, in order to ensure at the same time the electrical contact between cover and sole.
  • Figure 1 is a partially cut perspective view
  • Figure 2 is a cross section through a light fixture of the strip type, not equipped with lamp.
  • a lighting device for fluorescent lamps is composed of a sole 1, a cover 2 and two supports 3 for a base 4.
  • the support 3 comprises a base plate 5 on which the sole 1 rests In the base plate 5 there is provided at least one opening 6 making it possible to lock the sole 1 as soon as it is fully inserted in the support 3 of the base 4.
  • the upper left half of the support 3 of the base 4 is shown empty, and for more clarity, a part of the sole 1 is removed to reveal the conformation of the interior of the support 3. We thus see in particular a whole bead 7 separating the edges of the sole 1 from those of the cover 2
  • the sole 1 can support, as is well known per se, auxiliary devices for fluorescent lamps such as a starter capacitor, ballast choke etc., not shown.
  • a ballast choke When a ballast choke has a dispersion flux of some importance, and if, as is generally the case, the sole 1 and the cover 2 are made of steel, these two elements can start to vibrate and make noise.
  • an elastic distance element in this case a loop 8 of a steel bracelet 9, is inserted in the slot between the sole and the cover.
  • the bracelet 9 is preferably placed at the place where the ballast choke is fixed, for example in the middle of the choke; or two bracelets 9 are placed at the two ends of the self, not shown.
  • FIG. 2 A variant of the invention is shown in FIG. 2.
  • the elastic distance device is here presented in the form of loops 10 at the ends of a stirrup 11 also in a metallic strip, held by the ballast choke 12.
  • This variant makes it possible to achieve safe earthing of the cover 2 via the housing of the ballast choke 12 even if the cover 2 and the housing of the choke 12 are covered with layers of paint.
  • the loop 10 is shaped so that the cut edge of the sheet forming the cover 2 presses in a direction approximately perpendicular to part of the loop 10 so that the bare sheet which appears on this edge between in frank contact with the loop 10.
  • the lateral branches of the stirrup II have ribs or convex parts 13 whose sharp edges 14 are applied to the housing of the inductor 12 and pierce by scratching a coating of paint of this box to ensure good electrical contact.
  • the convex parts 13 serve to separate the supply wires 15 of the apparatus from the housing of the inductor 12 to prevent them from heating up in contact with the housing of the ballast inductor.
  • the bracelet 9 (fig. 1) can include loops 16 and 17 in which the supply wires 15 are kept. These loops 16 and 17 can be arranged in particular at places close to the top of the cover 2, as shown in FIG. 1 In view of the double insulation requirements, the bracelet 9 can be sheathed, at least at the location of the loops.
