Definitions

  • the known lamp cap is of the G38 type, a type having comparatively heavy metal pins whose centrelines are 38 mm removed from one another. Lamp caps of this or a similar type can be used in standardized lampholders. As a result, the known lamp can be used as a replacement for traditional halogen lamps, which do not require a high ignition voltage, in an environment comprising a standardized lampholder.
  • this object is achieved in that the base portion and the shell portion form one integral body, and in that the partition wall is made of ceramic material and is provided with a foot which is fixed on the base portion.
  • walls extend from the foot transverse to the partition wall, between which walls the seal of the lamp vessel is accommodated. A further increased resistance to high voltages can be achieved by this.
  • the walls may be connected to the shell portion, if so desired, for example with cement, so as to seal any interstices.
  • the partition wall extends to above the lamp cap in a favourable embodiment.
  • the capped electric lamp may be used, for example, as a studio or theatre lamp, for projection purposes, or for creating light spots.
  • the medium may comprise, for example, rare-earth bromide, mercury, mercury bromide, cesium iodide, and rare gas, for example, argon/krypton with a pressure of, for example 80, mbar.
  • the current conductors are screened from one another by glass tubes 8 and 9 where they run adjacent one another.
  • the lamp is provided with a ceramic lamp cap 10 of, for example, steatite with a base portion 11 and a shell portion 12 in which the seal 4 of the lamp vessel 1 is fixed.
  • the lamp cap has electric contacts 13 to which respective current conductors 3 are connected, and metal pins 13 which issue from the base portion 11 to the exterior.
  • the pins have not only a mechanical function in facilitating mounting in a lampholder, but also an electrical function, i.e. in making electrical contact with terminals of the lampholder, and thus with a supply. Separate electric contacts as in the known lamp are accordingly absent in this embodiment.
  • a partition wall 20 of insulating material is present which projects into the slit 5 of the lamp vessel and which forms an individual compartment 14 in the lamp cap for each current conductor 3 together with the respective electric contact 13.
  • the foot 21 of the partition wall 20 is fixed to the base portion with cement 22, for example, lamp cement.
  • the pins 13 issue from the lamp cap 10 to the exterior through ceramic rings 16 provided outside the lamp cap.
  • the lamp shown is suitable for being reignited in the hot state at a voltage of 50 kV.
