Definitions

  • the subject of the invention is a method and means the aim of which is to avoid the accumulation of static electricity on lighting devices; it also covers devices provided with such means.
  • lighting devices include a wall of transparent or translucent material which allows the passage of light flux; such a wall is produced by means of an insert which is made to the desired shape or profile from glass or a plastic material such as polycarbonate.
  • the main object of the invention is to provide a method and economical means capable of preventing the accumulation of static electricity on the surface of lighting fixtures, mainly on the surface of their transparent or translucent non-conductive walls. electricity.
  • this result is achieved by associating with these surfaces or with the material which constitutes them lines or strips conductive of electricity which are connected to a circuit for discharging static electricity.
  • all the lines or bands are connected together so as to form a network which concerns the entire surface or the wall in question.
  • the conductive lines or strips are obtained by depositing continuous lines of a conductive material, by applying a conductive wire or tape associated with an adhesive, by incorporation or hot inclusion in the material of a conductive wire.
  • longitudinal conductive lines can be made thereon on the surface or in the thickness during the extrusion operation.
  • the apparatus of Figures 1 and 2 is intended to contain two elongated fluorescent tubes. It comprises a wall 1 made of transparent material, for example polycarbonate, which is a cylindrical tube clamped between two end flanges 2, 3 made of rigid material, for example stainless steel.
  • the tube 1 made of transparent material has an outside diameter of approximately 130 mm; its length is fixed in correspondence with that of the fluorescent tubes which it must shelter, for example 0.60 m or 1.20 m or 1.50 m.
  • the device is sealed by elastomer seals 4, 5 which are contained in annular grooves in the flanges 2, 3.
  • the opposite ends of the polycarbonate tube 1 are compressed between the seals 4, 5 by means of an element.
  • central 6 which supports the electrical components and into which two opposite tightening screws 7, 8 are screwed.
  • the tube 1 made of transparent and insulating material is easily charged with static electricity, in spite of two metallic collars 9, 10 which surround it near its ends and which serve for its attachment to a wall or ceiling.
  • longitudinal polycarbonate wires 11 preferably made of copper, have been associated with the polycarbonate tube 1, by drowning them during extrusion just on its external surface. These wires are spaced on the circumference by a distance which does not exceed 60mm.
  • the wires 11 are joined together by means of a fixing collar 10 provided with a conductive braid 15 which is itself joined to the flange 3 by a welded bracket 14.
  • the longitudinal wires 11 can be connected to two wires circulars 12 and 13 connected to the ground circuit.
  • the lighting apparatus comprises two metal half-bodies 16, 17 assembled one below the other; the lower half-body .17 is provided at its lower part with a transparent polycarbonate wall 18 which generally has the appearance of a cup ending at its upper edge by a flange 19. The latter is tightened to using a metal ring 20 against the metal half-body 17 by means of a seal 21. With this conventional construction, the cup 18 easily accumulates static electricity.
  • conductive wires 22 are fixed to the outer surface of the cup 18 by adhesion, either by bringing a hot wire into contact with this cup, or by means of an adhesive substance.
  • Some wires 22A are arranged along parallels, other wires 22B are arranged along meridians. In all cases, the greatest distance between two neighboring wires does not exceed 60 mm at the point of their greatest spacing. Care is taken to ensure that the wires touch each other at all of their crossing points.
  • Several contact plates 23 are fixed by screws to the metal ring 20; each plate is folded so as to have a tongue 24 which is pressed against the wire 22A closest to the ring 20.
  • conductors not shown, connect the whole of the apparatus to earth.
  • the conducting wires constitute a network which is connected to earth with the rest of the lighting apparatus; this network presents meshes whose largest dimension does not exceed 60MM.
