Definitions

  • the invention relates to a lamp according to the preamble of claim 1 (known from US 2,694,775).
  • the rod-shaped fluorescent lamp or two rod-shaped fluorescent lamps in parallel with each other to enclose an elongated, tubular hollow body, which practically forms a lamp cover.
  • This Lamp covers usually contain specular reflectors Light control and can have different cross sections.
  • At the front of the lamp cover are firmly connected mostly glued head pieces provided that one or also two openings for inserting the fluorescent lamp or Have fluorescent lamps.
  • the openings are common provided with a cylindrical collar, which in turn in the socket housing protrudes and seals for one provides a secure seal.
  • the lamp cover must be Such lights to be replaced for lamp replacement.
  • the Handling the lamp cover is great because of it Length, especially if the person doing the work standing on a ladder, difficult.
  • the invention is therefore based on the object of a lamp to create according to the preamble of claim 1 which the lamp cover when changing the lamp easily and without Problems can be "handled".
  • the lamp according to the invention is on the front Ends of the lamp cover, i.e. on the head pieces, one each Fastened fastener over which the lamp cover with that on the ceiling, on the wall or on a special one Carrier fastened base body is connected. If the Lamp cover for replacing the lamp is loosened it swings around the connecting elements and remains hang parallel to the body. A hold by the fitter is then no longer necessary. This has both hands free to replace the lamp. Thereby, that the connecting elements are designed accordingly, move when refitting the lamp cover back to their starting position, i.e. they don't get between the sealing surfaces but they take their starting or Rest position again. In other words, the fasteners move automatically into their predetermined Position back. Depending on the construction of the Luminaire, inside or outside the body or the Socket housing.
  • the connecting elements are as resilient bracket, in particular made of plastic, so that it is due to the spring force inherent in the brackets when reattaching the lamp cover to the Move the socket housing back to its original position without to hinder the attachment.
  • fasteners such as for example hinges or the like.
  • the fitter who is standing on a ladder, for example, can concentrate on the essential work.
  • the lamp cover hangs on the connecting elements, when the lamp cover to replace a lamp is solved.
  • the fitter swings the lamp cover parallel to the base body and fastened this in the starting position, whereby the Move the fasteners back to their rest position automatically.
  • the base body 1 is in the area of each socket housing 4 through a connecting element 5 with the adjacent head pieces 3 connected to the lamp cover 2.
  • this connecting element takes a rest position, as for example 1 can be seen.
  • this embodiment is a plastic bracket with a corresponding, resilience inherent in it. If the Lamp cover 2 is loosened and swiveled, so it hangs on the two connecting elements 5, which then more or run less straight and by the weight of the Lamp cover are tensioned. The fitter can now, without that he has to hold the lamp cover, a fluorescent lamp Replace. Then he swings the lamp cover back to the starting or use position, whereby each connecting element 5, due to the inherent Spring tension, moves back to the starting position and does not hinder the attachment, and especially not between the sealing surfaces.
  • connecting elements in the form of a hinge or to assume the same.
