Definitions

  • the invention relates to a solid amalgam body or a solid amalgam former body for a fluorescent lamp, in particular a compact fluorescent lamp, according to the preamble of patent claim 1.
  • the amalgam or the amalgam former in the form of tablets, pills or sprayed-on metal rings have been introduced into the discharge vessel prior to the pumping and filling process and attached to the glass wall or the foot during the manufacturing process.
  • an additional tube is squeezed into an end of the vessel in which the body of the amalgam or amalgam former is located.
  • the amalgam or the amalgam generator there is also the possibility of attaching the amalgam or the amalgam generator to an additional electrode cap.
  • the object of the invention is therefore to provide a solid amalgam body or amalgam former body which can be introduced into the lamp during the manufacturing process in such a way that cooling of the amalgam or amalgam former in the lamp is not necessary.
  • the ferromagnetic amalgam body or amalgam former body can be introduced into the pump head of the lamp manufacturing machine before the lamps are pumped and held there magnetically. The amalgam or amalgam former body is then only released by the magnet in the pump head after the lamps have been pumped and filled with an inert gas and introduced into the pump tube. Cooling of the amalgam body or of the amalgam former body in a lamp part during the manufacturing process is thus eliminated.
  • the ferromagnetic component advantageously consists either of an iron powder which is pressed to the tablet with mercury and an amalgam former or of an iron core, for example in the form of a piece of wire which is embedded in an amalgam or amalgam former body.
  • the ferromagnetic component can, however, also consist of a ferromagnetic powder which is melted into the amalgam body or is embedded or alloyed into the amalgam former body.
  • a ferrule made of sheet iron as the ferromagnetic component, with which the amalgam or amalgam former body is encased.
  • the opening in the finished discharge vessel for releasing the amalgam or amalgam generator can take place with the aid of an inductive current surge.
  • an amalgam body is e.g. shown for a compact fluorescent lamp with 15 W power consumption.
  • the amalgam body 1 is a cylindrical tablet pressed from powder with a diameter of 1.5 mm and a height of 3 mm.
  • the compact consists of 44% by weight indium. 7.3% by weight of mercury and 48.7% by weight of iron.
  • the amalgam body 2 in FIG. 2 for a 15 W compact fluorescent lamp is likewise cylindrical in shape and has a length of 5 mm and a diameter of 1.7 mm.
  • An iron wire with a diameter of 1.2 mm is embedded in the amalgam body 2 along its axis as the core.
  • the amalgam of theischen has a composition of 44.5 wt% bismuth, 31.0 wt% tin, 19.5 wt% lead and 5.0 wt% mercury.
