Definitions

  • the invention relates to a lighting arrangement, in particular an arrangement of fluorescent tubes or LED modules.
  • florescent fluorescent tubes are often used to illuminate rooms.
  • each individual fluorescent tube has a finite length, places of reduced luminosity are formed at the transition points between two fluorescent tubes. Even when using a light-diffusing material, these darker areas are still visible.
  • the invention has for its object to provide a flexible lighting arrangement, which allows a uniform illumination at the most freely adjustable length of the lighting arrangement.
  • a lighting arrangement has a housing with an opening for emitting light in a main beam direction, a first lighting means and at least one second lighting means.
  • the first light source and the second lighting means are seen in the main beam direction next to each other and the length offset by an overlap length to each other.
  • the overlap length is infinitely adjustable. This ensures that any change in length of an elongated lighting arrangement can be achieved without production change.
  • the staggered arrangement results in a continuous over the length of the lighting illumination. A drop in light intensity at transition points between individual bulbs does not occur.
  • a uniform light image across the width of the lighting arrangement is advantageously achieved by mounting the lighting means near the longitudinal axis of the lighting arrangement.
  • the bulbs are fluorescent tubes. Each fluorescent tube is then enclosed in a fluorescent tube holder.
  • the fluorescent tube holder consists of a device carrier and at least two fluorescent tube sockets.
  • the fluorescent tube is advantageously asymmetrically attached next to the longitudinal axis of the device carrier of the fluorescent tube sockets.
  • the equipment carrier On the side facing away from the fluorescent tube side of the longitudinal axis of the equipment carrier, the equipment carrier advantageously on both sides in each case a paragraph and thus a shorter length than the fluorescent tube.
  • the equipment carrier advantageously on both sides in each case a paragraph and thus a shorter length than the fluorescent tube.
  • the equipment carrier advantageously on both sides in each case a paragraph and thus a shorter length than the fluorescent tube.
  • the equipment carrier advantageously on both sides in each case a paragraph and thus a shorter length than the fluorescent tube.
  • the equipment carrier In each case at the shoulder is a receiving element for receiving the portion of another such housing, in which the fluorescent tube is located. Two such housing can thus be pushed together.
  • the receiving element is advantageously designed such that the housing can be pushed continuously into one another.
  • an arbitrary overall length of the arrangement can be set within limits of any overlap length of the fluorescent tubes within limits.
  • the receiving element is formed by L Lucassausstanzungen in the equipment carrier, which yield flexible tabs.
  • one of the fluorescent tubes can advantageously also be shaded in the overlapping area by means of a throw-over profile or another shading device.
  • Fig. 1 shows a first embodiment of the illumination arrangement according to the invention.
  • Fig. 1 shows the lighting arrangement from below, ie from the direction of illumination.
  • fluorescent tubes are used as bulbs.
  • a housing not shown here, at least two equipment carriers 10, 20 are arranged.
  • Each device carrier 10, 20 includes a fluorescent tube 11, 21.
  • the equipment carrier 10, 20 are not shown here in their full length.
  • the device carrier 10 is cut in the middle.
  • the equipment carrier 20 is cut at its lower end.
  • the device carrier 20 corresponds in its design to the device carrier 10th
  • the equipment carrier 10 includes a fluorescent tube 11 which is held by fluorescent tube holders 12, 12a.
  • the equipment carrier 10 also has on the Side of its longitudinal axis on which the fluorescent tube 11 is a greater length than on the opposite side of its longitudinal axis.
  • the device carrier 10 thus has on the side facing away from the fluorescent tube 11, the longitudinal axis on both sides of a shoulder 25, 25a.
  • the device carrier 10 is open on the underside. It is closed on its top. On the side facing away from the fluorescent tube 11 of the longitudinal axis of the device carrier are each two L Lucassausstanzungen 13, 13a, 14, 14a on each side of the device carrier. The longitudinal cutouts 13, 13a, 14, 14a and the device carrier 10 form tabs 26, 26a.
  • the material of the device carrier 10 is flexible to a certain extent.
  • the device carrier 20 also has a fluorescent tube 21, which is held by fluorescent tube holders 22. Like the device carrier 10, the device carrier 20 on Leksausstanzache 23, 24. The Leksausstanzungen 23, 24 and the device carrier 20 also form here a tab 27th
  • the two device carriers 10, 20 are designed such that they can be pushed into one another. That in each case the side of the device carrier 10, 20 in which the fluorescent tube 11, 21 is located, enters the respective other device carrier 20, 10 at the level of the longitudinal punchings 13, 14, 23, 24 a.
  • the Leksausstanzungen 13, 14, 23, 24 allow bending of the respective device carrier 10, 20 and thus a recording of the equipment carrier 10, 20 into each other.
  • the equipment carriers are for this purpose made of an at least to some extent flexible material, e.g. Punching plate made.
  • Fig. 2 are the equipment carrier 10, 20 off Fig. 1 shown after pushing together.
  • the ends of the equipment carrier 10, 20 which contain the fluorescent tubes 11, 21 are inserted in this drawing in the other device carrier 20, 10.
  • the Leksausstanzungen 14, 13, 23, 24 were bent up when pushed. Since this drawing shows the lighting arrangement from below, the tabs 26, 26a, 27, which are formed by the equipment carrier and the Leksausstanzeptept 13, 14 and 23, 24 are now partially covered by the respective other equipment carrier 20, 10.
  • the device carriers 10, 20 can be pushed into one another within limits of any degree. The limits are given only by the length of the Leksausstanzungen 13, 14, 23, 24. This results in an overlap length L. In the overlap region is due to the overlap of the fluorescent tubes 11, 21 a higher light intensity.
  • Fig. 2 is a shading element 29 as an optional component, shown here a lamp cover. This is attached in the overlap region to at least one fluorescent tube 21 in order to shade the light emitted by it. In order to obtain even more uniform lighting, it is also possible to attach a smaller shading element to each of the two fluorescent tubes 11, 21.
  • Fig. 1 and Fig. 2 is also clearly seen as another optional feature that the fluorescent tubes 11, 21 are mounted near the longitudinal axis of the equipment carrier 10, 20.
  • the distance to the longitudinal axis is significantly smaller than the distance to the side of the fluorescent tube 11, 21 located side wall of the device carrier 10, 20th
  • Fig. 3 is a third view of the embodiment of Fig. 1 and Fig. 2 shown.
  • Fig. 3 shows a section through the axis S.
  • Fig. 2 Clearly visible are the two juxtaposed fluorescent tubes 11, 21. These are located respectively in a device carrier 10, 20. In the equipment carrier 20, the shading element 29 is still clearly visible.
  • the device carriers 10, 20 are arranged in a housing 28.
  • the housing 28 has an opening 31 on its underside. This opening is at least partially covered by a diffuser panel 30. This ensures a more even light emission.
  • the housing 28 can be designed so that a plurality of equipment carriers can be mounted in it.
  • the housing 28 can be brought by sizing to a desired length.
  • the diffuser aperture 27 can be easily adapted to the desired length.
  • Within the housing 28 then a plurality of equipment carriers are arranged.
  • the device carriers overlap each other at their ends. In order to achieve the most uniform illumination result, the device carriers advantageously overlap each other by an identical distance.
  • Fig. 4 the embodiment is made Fig. 1-3 shown in another view.
  • the longitudinal cutouts 13, 14 and the tab 26a can be seen particularly clearly here.
  • a device carrier 10 has been shown here.
  • On the representation of the fluorescent tube and the fluorescent tube holder was also omitted here.
  • the light of the bulbs is emitted in the main radiation direction R.
  • FIG. 5 shows an alternative (not covered by the claims) embodiment of the lighting arrangement.
  • the representation here is from below, ie from the direction of illumination.
  • a housing 49 which the housing 28 from Fig. 3 corresponds to a plurality of LED modules 54, 55, 56, 57.
  • Each LED module 54-57 includes a plurality of LEDs 50, 51, 52, 53 and two connecting elements 40, 41, 42, 43, 44, 45, 46, 47.
  • the LED modules 55 - 57 correspond to bulbs and are in succession in the housing 49 arranged and connected to each other by means of the connecting elements 43, 44, 45, 46.
  • the connecting elements 40-47 are also used for connection to the power supply. This is not shown here.
  • the plurality of light-emitting diodes (LED) 50-53 on each LED module 54-57 each extend over almost the entire length of the LED module 54-57. It is thus a uniform illumination over the entire length of the respective LED modules 54 - 57 reached.
  • the LED modules 54-57 have a uniform length.
  • an LED module 54 is laterally offset from the remaining LED modules 55-57. It overlaps longitudinally laterally with the adjacent LED module 55. The overlap is closer in Fig. 6 shown.
  • connection device 41 of the LED module 54 is connected to the connection element 42 of the LED module 55 by means of a flexible line.
  • the use of a ribbon cable is possible.
  • a plurality of LED modules 55-57 are arranged one behind the other.
  • a last LED module 54 is arranged laterally offset. By shifting the LED module 54 in the longitudinal direction, the overall length of the lighting arrangement can be adjusted. The length of the housing 49 can be accurately adjusted by simply sawing.
  • the LEDs 50-53 are laterally offset on the LED modules 54-57. That is, they are offset in the direction of the longitudinal axis of the housing 49 on the LED modules 55-57.
