Definitions

  • the invention relates to a low-voltage lighting system according to the preamble of claim 1.
  • connection of the connection lines to the power rails is still fixed, so that each pair of power rails requires its own connection lines.
  • busbars are not covered and are therefore not insulated, care must also be taken to ensure that a short circuit does not occur due to the holder being inadvertently placed incorrectly on the busbars.
  • a guide made of electrically non-conductive material projecting over the plane of the busbars was arranged between the busbars and the permanent magnets, which prevents the permanent magnets from being able to touch both busbars at the same time if they are inadvertently aligned transversely to the busbars.
  • the invention has for its object to design a low voltage lighting system of the type mentioned in such a way that the system can be handled more flexibly and is simpler.
  • the object is achieved by the characterizing features of claim 1.
  • the holder as a bridge-like carrier which receives the permanent magnets and, for the releasable connection of the lamp and / or the connecting line to the conductor rails, the carrier is optionally placed on the front or rear of the conductor rail,
  • a high degree of flexibility is achieved in that not only the lights but also the connecting lines can be arranged at any point on the busbars and several Schromschienen can be assembled into different lighting systems regardless of the connecting lines.
  • the arrangement of the busbars can either be adapted to changing spatial conditions, for example in showcases or shop windows, or can be selected on the basis of aesthetic considerations.
  • brackets of the brackets can be placed on the top of the busbars at a distance from a ceiling or the underside of a shelf, so that the weight of the corresponding lamp is borne by the busbars and is not held by magnetic force. In this way, even heavier luminaires can be arranged without stronger permanent magnets, which merely ensure reliable electrical contact.
  • the permanent magnets have at least one support element running parallel to the busbars and at least partially laterally abutting them, even without an additional guide arranged between the busbars it is achieved that the support of the holder is supported on the busbars in a rotationally secure manner and thus is always precisely aligned. Due to the fact that the length of the permanent magnets and support elements is shorter than the mutual distance between the busbars, one and the same permanent magnets and support elements can never touch both busbars simultaneously without further aids, so that there is no risk of a short circuit.
  • the holder 4 has a carrier 9 bridging the distance A, in which two permanent magnets 10, 11 are embedded.
  • the permanent magnets 10, 11 are fixedly arranged in the carrier 9 either by gluing or by tight fitting tolerances.
  • the permanent magnets 10, 11 have two pole strips 12 which project outwards and inwards and which are arranged in parallel and at a mutual distance from one another and which are not only magnetizable but also electrically conductive. The mutual distance between the permanent magnets 10, 11 is selected so that the support 9 is supported by the pair of pole strips 12 from the busbars 2, 3.
  • the two pole strips 12 of each pair of pole strips are symmetrical to the associated busbar 2 or 3, each pole strip touching the busbar at a spacing from a vertical plane passing through the longitudinal axis of the busbar.
  • the pole bars 12 on the busbars 2, 3, the pole bars 12, in conjunction with the holding force of the permanent magnets 10, 11, result in a partially positive and partially non-positive guidance, as a result of which the holder 4 sits firmly and securely on the busbars 2,3 .
  • the length L of the permanent magnets 10, 11 essentially corresponds to the length of the pole strips 12 and is shorter than the distance A of the busbars 2, 3.
  • a contact plate 13 which connects them to each other in an electrically conductive manner, is soldered onto the inner ends of the pairs of pole strips.
  • Each contact plate 13 is connected to a current-carrying cable 14, 15.
  • the cables 14, 15 are inserted through a threaded nipple 16 screwed onto the support 9 and lead to a version of the lamp 5 (not shown) 14.15 covers.
  • the bracket 6 is constructed essentially the same as the bracket 4. It is only on the support 9 instead of the threaded nipple 16, a cable bushing 18 is arranged, which serves as a strain relief for the two connecting lines 7 with the aid of a threaded pin 19.
