Definitions

  • the invention relates to a luminaire for a fluorescent lamp with a translucent protective tube enclosing the lamp according to the features of the preamble of claim 1.
  • Luminaires of this type which are designed for increased protection conditions, have such protective tubes, which 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.
  • Such lights have proven themselves, but their assembly is difficult:
  • the fluorescent lamps have contact pin pairs at the end, 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. A certain amount of force is required for this rotary movement and also for the lateral insertion, this presupposes that the lamp can also be properly gripped manually.
  • the protective tube stands in the way of 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 turned 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. As a result, however, 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 invention aims to improve these known constructions so that the lamp can be assembled more easily without obstructing the heat and light radiation by the long screw rings which were previously necessary.
  • the invention proposes measures which are the content and subject of the characterizing part of the patent are 1.
  • FIG. 1 and 2 show a longitudinal section through one end of a lamp, the two representations illustrating different moments when the lamp is inserted;
  • Figure 3 is a view of the disc along the section line III-III in Figure 1;
  • Figure 4 is a view corresponding to Figure 3, but in a different embodiment;
  • Fig. 5 shows a longitudinal section through a further embodiment of the invention.
  • the lamp shown in Figures 1 and 2 has a basically known structure: on a lamp bar 1, in which the wiring and the devices necessary for the operation of the fluorescent lamp 2 are, sockets 3 are provided at the end, with the usual rotary star to the side Insert the contact pins 4 of the lamp 2 and then turn the lamp by 90 °, thereby bringing the contact pins 4 into the contacting position with the live parts of the socket 3.
  • the lamp 2 is surrounded by a translucent protective tube 5 which, as can be seen from FIGS. 1 and 2, is almost as long as the lamp 2.
  • screw rings 6 are provided at the end with an outer seal 7 which abuts on the outer circumference of the protective tube 5, and with an internal thread 8, which can be screwed onto the external thread 9 of the socket 3.
  • nose-like projections 11 are arranged along the inner circumference of the inner wall of the screw ring 6 at equal intervals, which have a wedge-like suit 12 with an adjoining, radially outward offset section 13, so that a paragraph is formed.
  • a disk 14 In the end region of the protective tube 5, a disk 14 is provided with a centrally located, elongated recess 15 through which the contact pins 4 of the lamp 2 protrude.
  • the edge 16 of this disc 14 is flanged and directed against the protective tube 5.
  • the flanged edge 16 of the disk 14 also has a radially projecting ring zone 17.
  • a plurality of U-shaped cutouts 18 are provided which are arranged at equal distances from one another. The number of these cutouts 18, their distribution and their arrangement corresponds to the number, arrangement and distribution of the nose-like projections 11 on the screw ring 6.
  • the boundary surface 19 provided between the two legs of each cutout 18 is expediently slightly inclined, the angle of inclination, based on the axis of the lamp 2, opening outwards.
  • the radial distance 20 of this boundary surface 19 is slightly larger than the radial distance 21 of the highest points of the nose-like projections 11.
  • the procedure is as follows: The lamp 2 is inserted into the protective tube 5, which is approximately as long as the lamp itself.
  • the lamp 2 is now inserted together with the protective tube 5 and the screw rings 6 from below (FIG. 1) into the socket 13, the lamp 2, the sheathing be 14 and the screw ring 6 are approximately concentric with each other. If the contact pins 4 of the lamp 2 are retracted into the socket 3 from the side (FIG. 1), the screw rings 6 are now rotated by 90 °, and this rotary movement is followed by the disk 14, which has a positive fit via the recesses 18 and the projections 11 is connected to the screw ring 6, and the lamp 2, which is positively connected to the disk 14 via its contact pins 4 and the recess 15.
  • the projections 11 are provided on the inside of the screw rings 6 and the cutouts 18 in the outer ring zone 17 of the disk 14, it is fundamentally possible to reverse the arrangement of these active elements, that is to say to arrange tooth-like tabs on the ring zone 17 and on the inside of the screw ring 6 corresponding longitudinal grooves that can extend through the thread 8.
  • the edge 16 of the disk 14 is also flanged and provided with a radially projecting ring zone 17.
  • such a flat design of the disk 14 would require a somewhat larger overall length of the screw ring 6.
  • FIG. 5 shows another embodiment of the invention in the representation according to FIG. 2, the same being used in this figure to designate it and equivalent parts, the same reference numbers are used.
  • the disk 14 here has a conical collar 22 which opens towards the protective tube 5 and which has teeth 23 on its outside which extend in the direction of the cone-producing members.
  • a shoulder 24 is formed adjacent to the internal thread 8 of the screw ring 6, conically corresponding to the collar 22 of the washer 14 with teeth 25 corresponding to its teeth 23.
  • the described exemplary embodiments show that fundamentally different components can be used as coupling elements and counter-elements; in one case there are nose-like projections and grooves that interact in a form-fitting manner, and in the other case (FIG. 5) there are toothed sections.
  • other profiles would also be possible in principle, for example corrugations, which come into positive connection with one another or can be released from such a positive connection due to the axial displacement of the construction parts discussed here. Since the forces to be transmitted during assembly are not too great, surfaces with high friction values could also be used as coupling elements and counter elements.
  • the choice of the corresponding coupling elements and counter-elements is primarily based on manufacturing considerations.
  • the solution proposed according to the invention is extremely expedient since it can be used in practice with all standard sockets, it is only necessary to replace the screw ring and insert the washer 14.
  • the figures also illustrate that the screw ring 6 covers the end of the protective tube 5 only over a small area, so that light and heat can flow out of the electrode area of the lamp 2 almost unimpeded.
