Definitions

  • the invention relates to a lamp, lighting system or the like, comprising a U-shaped housing part with an attachable lid for receiving the electrical components for a light source, wherein the housing part directly or indirectly on a ceiling or a wall can be fixed, and the free leg ends to the inside the housing part are bent to form adhesive strip surfaces for sealing strips against which the lid longitudinal edges for sealing closure of the lid can be pressed.
  • the light band system comprises a kind of rod-shaped housing part, which consists of a U-shaped housing part with attached lid.
  • the lighting strip system can be fastened directly to the ceiling surface, whereby suspended constructions are also common, so that the lighting system is suspended from the ceiling.
  • the housing area is sealed, so that dust and / or water particles can not penetrate into the interior of the housing.
  • mounting rails which are equipped with sealing tapes, which are glued by hand on the shaped leg end portions of the housing part.
  • the housing part is formed with its leg ends in such a way that for this purpose special adhesive strip surfaces are present, onto which then the sealing strip is pressed.
  • this work of applying the sealing tapes designed with back adhesive surface very labor-intensive, because exactly the adhesive strip surfaces are to be adhered to in this way to achieve the sealing closure with the lid longitudinal edges.
  • an exact application of the sealing tape to the adhesive strip surfaces is not achieved, then it happens that one or the other mounting rail does not have the appropriate sealing requirements.
  • document AT 413 238 B shows a lamp with a housing part and an attachable lid, the free leg ends of the lid are bent to the inside of the housing part and form adhesive strip surfaces for sealing strips which are pressed against the lid longitudinal edges for a tight closure of the lid.
  • the object of the invention is based on such a support rail for a lighting system of fluorescent tubes continue to form that is better designed on the one hand in terms of sealing requirement, and on the other hand, the attachment of the sealant designed much easier.
  • the free leg end of the lid longitudinal edges are bent or formed inwardly such that they each form an inwardly facing edge of the adhesive strip area partially open channel in which an elastomeric sealing tape or a cord can be pressed, which pressed in the mounted state of the lid on the inwardly curved rounded edge of the adhesive strip surface.
  • the inflection of a partially open channel in the region of the leg ends in conjunction with a rubberized sealing strip or a string brings significant advantages in the determination of the sealant, namely the fact that the sealing strip is reduced due to its elongation in cross-section, so that an easy insertion into the Channel is given. With this design, the assembly times for attaching the sealant are significantly reduced.
  • a partial region of the elastomeric sealing strip protrudes in the region of the channel openings, which in the mounted state of the cover presses against the inwardly curved rounded edge of the adhesive strip surface. Due to this arrangement, a fixedly fixed position of the sealant is provided at the leg ends, so that even with exactly mounted cover over the length of the support rail a sealing contact of the lid is achieved.
  • the sealing tape or the cord has a circular cross-section, so that a compressed, pressed position over the length of the mounting rail is achieved.
  • the invention proposes that the free leg ends of the lid longitudinal edges are bent after the molded channel so that they form a parallel contact area with the correspondingly shaped leg ends of the housing part. This training ensures in particular a dimensionally stable and accurate sealing system of the partially opened channel at the leg ends of the housing part.
  • the free leg ends of the housing part are bent or formed inwardly such that they each form a partially open channel in which an elastomeric sealing strip can be pressed, which pressed in the assembled state of the lid on an inwardly curved rounded edge on the lid, the same effect is achieved.
  • the sealing tape is arranged in the housing part instead of in the lid.
  • the single figure shows in particular a support rail 1 in cross section, which is intended for a lighting system of fluorescent tubes, not shown.
  • the support rail 1 in this case comprises a U-shaped housing part 2, with an attachable cover 3, wherein in the inner region of the housing part 2 corresponding to the likewise not shown electrical components for the fluorescent tubes are arranged.
  • At the ends are still brackets, also not illustrated, arranged for the fluorescent tubes that protrude through the lid 3, between which then the fluorescent tube or the fluorescent tubes are clamped.
  • Corresponding support points 4 are provided in the bottom region of the housing part 2 for this purpose.
  • the free leg ends 5 and 6 are bent to the inside of the housing part 2, to form adhesive strip surfaces 7 and 8 against the lid longitudinal edges 9 and 10 for sealing closure of the support rail 1 can be pressed.
  • the sealing strip 17 and 18 has a circular cross-section, wherein a portion of the circular surface of the partially open channel 15 and 16 protrudes, and this in particular with the rounded edge 19 and 20 of the adhesive strip surface 7 and 8 comes into contact when the lid 3 is mounted on the housing part 2.
  • the invention proposes that the free leg ends 11 and 12 of the lid longitudinal edges 9 and 10 following the molded channel 15 and 16 are bent such that they form a parallel contact area 21 and 22 with the correspondingly shaped leg ends 5 and 6 of the housing part 2.
  • the sealing tape is stretched, so that it can be easily pressed into the partially opened channel 15 and 16. If the elongation is removed, then the sealing strip 17 or 18 with its circular cross-section automatically pulls itself into the open circular shape, as can be seen in the figure.
  • the channels 15 and 16 have a slight overhang 23 and 24 in the upper area. In a too tight seat is thus the possibility that the elastomeric material can migrate into this area, so that a corresponding interference fit is achieved even under thermal stress.
  • the free leg ends 25 and 26 of the housing part 2 may be formed according to how the lid 3 to 17 and 18 to arrange sealing strips.
  • the leg ends 25 and 26 are bent or formed inwardly, that they each form a partially open channel, as described in cover 3, in which an elastomeric sealing strip 17 and 18 can be pressed.
  • an elastomeric sealing strip 17 and 18 can be pressed.
  • the lid 3 In the assembled state of the lid 3 then pressed inwardly curved rounded edge on the cover 3 on the respective sealing strip 17 and 18. This leads to the same technical effect as in the described embodiment of the sealing strip 17 and 18 on the lid. 3
