Definitions

  • the invention relates to a discharge lamp according to the preamble of patent claim 1.
  • Such a discharge lamp is disclosed for example in the patent EP-A-0 922 297.
  • This patent describes a fluorescent lamp with a tubular discharge vessel and a noble gas enclosed therein.
  • This lamp has elongated, parallel to the lamp axis extending electrodes, which serve to generate a gas discharge. At least one of these electrodes has a lead-out from the interior of the discharge vessel portion which is further developed as a power supply and attached to the inner wall of the tubular discharge vessel.
  • the lamp base is equipped with two contact pins, which are each electrically connected to one of the lamp electrodes.
  • the discharge lamp according to the invention is distinguished from a generic discharge lamp in that their base contacts are each connected to an electrically conductive spring element, wherein each spring element on the Wall of the at least one tubular lamp vessel rests and makes electrical contact between each one arranged outside the lamp vessel portion of a lamp electrode with a base contact.
  • the spring elements ensure a secure electrical contact between the base contacts and arranged outside the lamp vessel electrode sections and a simple base of the discharge lamp.
  • the spring elements are designed as leaf springs with curved ends, wherein the curved leaf spring ends are each in electrical contact with one of the aforementioned electrode sections.
  • the bulges ensure a sufficiently large contact area between the leaf springs and the electrode sections and prevent damage to the surface of the electrode sections.
  • the leaf springs are advantageously each provided with at least one strain loop, through which the different thermal expansion coefficient of the lamp vessel and the leaf springs is taken into account.
  • the spring elements are advantageously each connected by a solder joint to the corresponding electrode portion.
  • the solder joint has the advantage over a welded connection that it can be produced by high-frequency induced heating of the socket contacts when the electrode sections arranged outside the at least one lamp vessel or the spring elements have previously been coated with solder paste or have been tin-plated ,
  • the electrode sections designed as a current supply are advantageously mounted on the inner wall of the at least one tubular lamp vessel and the spring elements are therefore on the inner wall of the lamp vessel and are in mechanical and electrical contact with these electrode sections. As a result, the electrode sections and also the spring elements can be better protected against damage and contact.
  • a first end of the at least one lamp vessel is equipped with a base sleeve, which is provided as part of the lamp cap with the at least two base contacts, wherein the base contacts are each connected to an outgoing from the first end of the at least one lamp vessel electrode portion ,
  • the power supply of the electrodes is done in the preferred embodiment, therefore, exclusively on the first end of the at least one lamp vessel. In this case, it is therefore sufficient to base the discharge lamp only on one side or to provide the other end of the at least one lamp vessel with a base sleeve without electrical contacts, which only serves to hold the lamp in a lamp holder.
  • at least one electrode section designed as a current supply is brought out of both ends of the at least one lamp vessel, which abuts against the inner wall of the at least one tubular lamp vessel and which is connected to a socket contact.
  • the base sleeve or the socket sleeves of the lamp base are advantageously made of an electrically insulating, thermoplastic material.
  • a fusion of the base sleeve or the socket sleeves is made possible with the ends of the at least one lamp vessel.
  • the lamp rotor has at least one base sleeve with a cup-like receptacle for one end of the at least one lamp base, whose diameter is matched to the outside diameter of the corresponding end and in which the spring elements are arranged.
  • each base sleeve has a suitable for high-frequency induced heating means which is arranged in each case in a receiving the corresponding base sleeve enclosing annular groove. These means may be due to high frequency induction voltage pulses are heated so that the thermoplastic material of the base sleeve melts in the region of the groove and forms a fused connection with the at least one lamp vessel after hardening.
  • An electrically insulating means may advantageously be arranged between the spring elements arranged in the same receptacle.
  • the discharge lamp is a gas discharge lamp having a noble gas or a noble gas mixture as the discharge medium.
  • the discharge lamp has a rod-shaped, tube-like and gas-tight discharge vessel 1 made of glass.
  • One end 13 of the discharge vessel 1 is sealed gas-tight by means of a stopper 10 and glass solder, while the other end (not shown) has been melted off.
  • the discharge medium is enclosed in the interior 11 of the discharge vessel 1.
  • the stopper 10 has a pumping stem 12, via which the discharge medium was filled into the interior 11 of the discharge vessel 1, and which was subsequently sealed gas-tight.
  • two opposing strip-shaped, electrode-like electrodes 2, 3 are applied, which serve to generate a gas discharge in the interior 11 of the discharge vessel 1.
  • the electrodes 2, 3 With a dielectric 14, for example, with a thin glass layer and / or a phosphor layer, coated. For this reason, in the discharge lamp during operation between the electrodes 2, 3 forms a dielectrically impeded discharge.
  • the electrodes 2, 3 each have a guided through the closure 10, protruding from the interior 11 of the discharge vessel 1 section 20, 30, which rests outside of the discharge chamber 11, in the region of a discharge vessel end 13 on the inner wall of the discharge vessel 1.
  • Electrodes sections 20, 30 serve as a power supply for the arranged within the discharge chamber 11 sections of the electrodes 2, 3.
  • Both ends 13 of the tubular discharge vessel 1 are provided with an existing of an electrically insulating, thermoplastic plastic base sleeve 4, which together form the lamp cap.
  • Only one of the two socket sleeves 4 is equipped with the contact pins designed as electrical socket contacts 5, 6.
  • Both socket sleeves 4 have a cup-like receptacle 40 for each one end 13 of the discharge vessel 1.
  • the diameter of the receptacle 40 of each Sokkelhülse 4 is matched in register to the outer diameter of the respective end 13 of the discharge vessel 1.
  • both base sleeves 4 are provided with depth stops 41, which determine the immersion depth of the Enladungsgefä touchden 13 into the receptacle 40.
  • both socket sleeves 4 have a preferably ferromagnetic metal ring 7, which is arranged in a receptacle 40 annularly enclosing groove 42. These metal rings 7 serve to produce a permanent fusion bond between the thermoplastic material of the base sleeves 4 and the outer wall of the discharge vessel ends 13 by means of high-frequency induction voltage pulses.
  • two metallic leaf springs 8, 9 are arranged, which produce an electrical connection between in each case a contact pin 5 or 6 and an electrode section 20 or 30.
  • the two leaf springs 8, 9 each have a curved end 80, 90 which rest respectively resiliently on one of the electrode sections 20 and 30 and are soldered thereto.
  • the other end of the leaf springs is each clipped onto a base pin 5, 6 and soldered or welded to this.
  • Both Battfedern 8, 9 also have an expansion loop 81, 91 which is formed by an approximately U-shaped bent portion of the spring 8, 9.
  • the discharge lamp may also be more than just two electrodes and each of the socket sleeves may be provided with electrical contacts, so that the electrode sections serving as power supply leads can be led out of both discharge vessel ends.
  • the invention can also be applied to discharge lamps having electrodes mounted on the outer wall of the at least one tubular lamp vessel. In this case, the spring elements bear against the outer wall of the lamp vessel.
