Definitions

  • the invention relates to a luminaire for discharge lamps, in particular for a fluorescent lamp with the features according to the preamble of claim 1.
  • Luminaires of this type which are designed for increased protection conditions, have such protective tubes that are overlapped at the ends by screw rings, which are screwed tightly and tightly to the sockets and which accommodate seals at their free ends and carry seals which bear against the protective tube OS 31 12 962, DE-OS 32 09 481 and AT-PS 382 226).
  • Such luminaires have proven themselves, but their assembly is difficult:
  • the fluorescent lamps have pairs of contact pins at the ends, which are inserted laterally into the voltage-carrying sockets, whereupon the lamp must be rotated by 90 ° so that the contact pins get into the contact-making position of the socket and further the lamp is prevented from sliding out of the socket by itself.
  • the protective tube prevents this manual access. So far it has been used to make the protective tube about 20 to 25 mm shorter than the lamp itself, so that when mounting at least on one side of the lamp so much space is left between the protective tube and the socket, so with two fingers the lamp can be gripped, held and rotated by hand. So that the light is appropriately sealed with these short protective tubes, the screw ring must now be so long that it can grip the protective tube end reliably and tightly.
  • the screw ring extends exactly over that area of the lamp in which the electrodes of the lamp are arranged and in which most of the heat is generated during operation.
  • This axially long screw ring not only hinders the light, but also the heat radiation, for which reason metallic sleeves have been used here in known designs to promote heat dissipation, but this is a technically unsatisfactory solution.
  • the object underlying the invention is now such Avoid technically unsatisfactory solutions and still provide a protective tube that is as long as the lamp, so that short, sealing screw caps or screw rings can be used, so that the heat radiation in the electrode area of the lamp is not obstructed, whereby a measure must now be considered is so that the lamp located in the protective tube and now no longer accessible can be used in a conventional fluorescent lamp holder.
  • the invention proposes those measures which are the content and subject of the characterizing part of patent claim 1.
  • the outer surface of the protective tube is not impaired in the region near the socket, so that despite this plug there is a constant cylindrical shape in the longitudinal direction of the protective tube, with which the seal of the screw ring can enter into a perfect operative connection, and indeed over the entire range of their axial adjustment, which is necessary when mounting the lamp.
  • these screw rings must be pushed on at the front and moved so far towards the center of the lamp that the contact pins of the lamp can be inserted into the socket from the side. If the lamp is inserted into the socket in this way and rotated into the contacting position thanks to the measure according to the invention, only then can the screw rings equipped with the seals be pushed against the socket and screwed to it.
  • FIG. 1 shows a bush-like plug in view, cut in half; 2 shows the view of the bush-like plug according to FIG. 1 (viewing direction arrow A); Fig. 3 shows a longitudinal section through one end of a fluorescent lamp with protective tube, screw ring and socket.
  • the socket-like plug 1 is made in one piece from an electrically insulating, heat-resistant material. It has a cylindrical wall 2 and a bottom 3, in the plane of this bottom 3 a collar 4 protrudes laterally and on the outside of the cylindrical wall 2 there are several circumferential, lip-like sealing strips 5. In the central region of the bottom 3, an elongated hole cutout 6 is provided here, the axial length of which corresponds at least to the usual spacing of the contact pins 7 at the respective ends of a fluorescent lamp 8. In the transition area between the outside of the cylindrical wall 2 and the contact surface of the collar 4, a shoulder 9 is provided, which can be formed all around, or which can be formed by a plurality of bumps distributed along the circumference.
  • the cylindrical wall 2 On the inside of the cylindrical wall 2 there are a plurality of axially parallel ribs 10 with a leading edge 11 tapering outwards in a wedge shape. A number of free openings are also left in the bottom 3, which are arranged here in alignment with the ribs 10. Instead of a single elongated hole cutout 6, two individual cutouts can also be provided in the bottom 3 for receiving the contact pins 7.
  • the diameter of the plug 1 is about 3 times its axial length.
  • FIG. 3 shows in longitudinal section its use in a fluorescent lamp with a protective tube 13.
  • sockets 15 are arranged with the rotary star usual for such lamps, which also have a thread 16.
  • the plug 1 shown in FIGS. 1 and 2 is inserted.
  • This plug 1 rests with the collar 4 on the front edge 19 of the protective tube 13, which thus forms a stop for the plug.
  • the cylindrical section with the sealing strips 5 protrudes into the protective tube 13 and, due to its elastic behavior and its dimensions, ensures that the plug 1 is held in the protective tube 13 in a rotationally fixed manner.
  • the paragraph 9 at the location described above serves as a centering between the two construction parts 1 and 13 discussed.
  • the lamp 8 is now inserted from one end and angularly positioned relative to the protective tube such that the contact pins 7 provided in pairs protrude through the elongated hole recess 6 of the plug 1 . Then the screw rings 17 with their seals 18 are pushed onto both ends of the protective tube 13 and offset so far towards the center of the protective tube 13 that their outer edges are somewhat offset from the front edge 19 of the protective tube 13.
  • the lamp 8 is now connected to this protective tube 13 in a rotationally fixed manner.
  • the contact pins of the lamp 8 are now, as is known per se, retracted or inserted into the rotary star of the socket 15 and then the protective tube 13 is rotated, with which the lamp 8 is connected in a rotationally fixed manner until the lamp reaches its contacting position version 15 has reached.
  • the screw rings 17 are screwed onto the threads 16 of the sockets 15. To replace a used lamp, the steps described above are done in reverse order.
  • ribs 10 with the leading edges 11 on the inside of the cylindrical wall 2 of the plug 1 on the one hand facilitate the insertion of the lamp 8 during assembly and also serve additionally as a centering means which holds the lamp 8 in the center of the protective tube 13.
  • the protective tube 13 it is possible to make the protective tube 13 approximately as long as the lamp, so that only relatively short screw rings 17 can be used, so that the heat generated in the electrode region of the lamp can be radiated and dissipated almost unhindered.
  • the openings 12 provided in the bottom 3 of the plug 1 at the edges serve to enable and allow this air movement.
  • the recess 6 which is designed as an elongated hole in the exemplary embodiment shown, forms a coupling member in connection with the contact pins 7 of the lamp for filming.
  • This recess 6 can therefore have very different shapes, for example a cross shape, or openings can be provided in pairs, through which the contact pins 7 can be passed and which, due to their design, ensure that the lamp 8 is carried when the protective tube 13 is rotated.
