Definitions

  • the invention relates to a low-voltage lighting system consisting of at least one busbar which can be fastened to the ground and lighting fixtures which can be fastened thereon by means of adapters, the busbar consisting of at least two rods of magnetic material which are arranged parallel to one another and have different electrical potential and are separated from one another by an insulating layer are and are held together by this.
  • Lighting systems which have busbars which are arranged parallel to one another and are separated from one another by an insulating layer, the rods being embedded in this insulating layer over a large part of their circumference. Only two surfaces of the rods, which are opposite each other by 180 degrees, are free of the insulation. This results in a busbar of approximately circular cross section. Since the contact surfaces of the two rods lie diametrically opposite one another, the adapters for fastening the lighting fixtures to the busbar are designed in the form of a clamp. The clamp legs touching the contact surfaces serve to establish the electrical contact from the busbar to the lighting fixture. The production of such busbars is complex since the rods have to be cast into the insulation material.
  • the contact surfaces of the rods on opposite sides of the rail the attachment of the adapter to the busbar is also problematic.
  • the clamp legs are pressed against the contact surfaces of the busbar with the aid of a spring. Since the lighting systems according to the invention should be variable in the arrangement of the lighting fixtures on the rails, it is necessary that the lighting fixtures can be moved quickly and easily on the rail.
  • the clamp adapters have the disadvantage that the material of the clamp spring becomes fatigued when the lighting fixtures are frequently moved, and thus a firm hold on the rail is no longer guaranteed.
  • the production of the clip adapter is complex. Inevitably, these adapters require a design whose transverse expansion is significantly larger than the conductor rail diameter. If the premises to be illuminated require that several busbars are arranged closely next to one another, the distance between individual busbars is limited by the expansion of the brackets in order to avoid short circuits.
  • the previously known system has the disadvantage that the busbars are limited to two current-carrying rods united in them.
  • the busbars are limited to two current-carrying rods united in them.
  • the invention is therefore based on the object of designing a low-voltage lighting system of the type mentioned at the outset such that the lighting fixtures can be fastened to the conductor rail in a simple, reliable manner and the conductor rail is not limited to two current-carrying rods.
  • the invention solves this problem in that the contact surfaces of the rods lie side by side in one plane and the insulating layer between the mutually facing surfaces of the adjacent rods connects them to one another to form the busbar, and in that the adapters have two electrically and magnetically conductive contact surfaces arranged parallel to one another in one plane have for the current draw from the adjacent contact surfaces of the rods, the contact surfaces of the adapters being separated from one another by an electrically non-conductive permanent magnet and being fastened thereto.
  • the bars are largely exposed and are only separated from the insulating layer on the surfaces of adjacent bars facing one another.
  • the insulating layer can e.g. B. be an adhesive tape, so that the insulating layer also causes the cohesion of the rods in the busbar.
  • the contact surfaces of the busbar lie next to one another in one plane, adapters with contact surfaces likewise lying in one plane can be used.
  • the contact surfaces are attached to a permanent magnet arranged between them, so that the contact surfaces also become magnetic.
  • the busbars according to the invention also offer the advantage that contact surfaces are present both on the top and on the bottom of the busbar. If the conductor rail is attached at a sufficient distance from the surface, e.g. B. by hanging the track from the ceiling, lighting fixtures can be attached to it both on the lower and on the upper side. The lighting fixtures can be directed in such a way that some of them illuminate the surface and thus generate indirect lighting and another part of the lighting fixtures is directed directly into the room as spotlights. Because the adapters have a transverse extent which corresponds approximately to the distance between the longitudinal axes of the rods, the distances between individual busbars are minimally small. In addition, the manufacture of the adapter according to the invention and the manufacture of the busbars are considerably simplified.
  • the rods can be rectangular in cross section, e.g. B. be square, which makes the production of the busbars from such rods even easier.
  • each facing sides of the rods are flattened and serve as fastening surfaces for the insulating layer.
  • Claim 6 has a further advantageous feature of the adapter according to the invention. This makes it possible to quickly and easily separate the lighting fixture from the adapter and the free one Use the adapter as a fastening element for the busbars on the surface.
  • the feature of claim 7 offers the advantage of being able to quickly and easily detach the lighting fixtures from the line elements which are fastened to the adapter and to replace them with a different type of lighting fixture.
  • a further advantageous embodiment of the busbars according to the invention is given by the feature of claim 8. If the insulating layer on both sides of the busbar protrudes beyond the plane formed by the contact surfaces of adjacent rods, a rotation of the contact surfaces of the adapters in this plane cannot lead to a short circuit, since the web-shaped design of the insulating layer prevents the contact surfaces of the adapter from twisting the contact surfaces of the conductor rail.
  • the features of claim 10 provide a magnetic adapter which is provided for fastening the busbars to the substrate, a wall or a ceiling. Its structure is identical to the adapter for the lighting fixtures. As already stated above, the magnetic adapters are designed in such a way that they can be used either as a fastening element for the lighting fixtures or as a fastening element for the busbars themselves.
  • An alternative fastening option is given by claim 11.
  • About 2 cm long sleeves are attached to the outer bars of the busbar and z. B. attached with grub screws to the bars.
  • Two opposite sleeves are on a z. B. cube-shaped base, e.g. B. made of plastic, screwed tight.
  • the base On its surface facing away from the busbar, the base has a blind hole into which the bolt of a screw is inserted, which is dowelled on the base.
  • a further hole is made in the side of the base, which opens into the blind hole.
  • the bore has a Internal thread into which a grub screw can be screwed, which presses against the screw bolt when it is tightened and holds it in place.
  • a socket for connecting the power supply lines can be attached to each of the sleeves.
  • the lighting system according to the invention is not limited to busbars with only two rods combined to form a busbar.
  • the busbar consists of three rods arranged parallel to one another, with adjacent rods having different electrical potentials.
  • the insulating layer is arranged between two rods in such a way that the contact surfaces of the three rods arranged parallel to one another lie in one plane.
  • the middle rod is preferably the neutral conductor, while the outer rods represent the phases.
  • the features of claim 13 provide a further busbar in which a total of eight bars are combined to form a busbar which is approximately square in cross section. Three adjacent bars form the sides of the square. The spaces between the bars are one insulating mass filled. If square bars are used to form the busbar, two adjacent bars can be connected to one another with the aid of an insulating adhesive.
  • the insulation body is advantageously designed as an extrusion part, so that the rods can be introduced into channels provided for this purpose. With the aid of such a rail, it is possible to implement a four-phase system, the rods enclosed by two outer rods being used as neutral conductors and the outer rods attached to the edges representing the four phases.

  • FIG. 2 A further embodiment of a busbar according to the invention is shown in broken representation in FIG. 2. This consists of three parallel bars (2, 3 and 7).
  • the rods (2 and 3) are designed as in Fig. 1, while the intermediate rod is rectangular in cross section.

  • FIG. 3 shows a magnetic adapter (8) according to the invention. It consists of two steel sheets (9 and 10) which are arranged in parallel and have a rectangular outline and which are separated from one another by means of a magnet (11) which is made of a non-conductive material are separated.
  • the steel sheets (9 and 10) are attached to the opposite side surfaces of the magnet (11), for. B. glued.
  • the contact surfaces (12 and 13) that make contact with the busbar (1) protrude beyond the upper edge (14) of the magnet (11).
  • the magnet (11) On its surface facing the busbar, the magnet (11) has a roof-shaped web (15) which is also made of non-conductive material. 1 and 2, the contact surfaces (12 and 13) are lifted off the contact surfaces of the current rail (1) and thus a short circuit is prevented.
  • the steel sheets (9 and 10) are extended beyond the front edge of the magnet (11).
  • the extensions (16 and 17) are provided with bores (18) through which the screw bolt (19) of screws (20 and 21) can be inserted.
