Definitions

  • the introduction of mercury in discharge lamps, in particular low-pressure discharge lamps, is known and can be done, for example, with a metal strip, which is coated accordingly.
  • a low-pressure discharge lamp in which a carrier element, which is plate-like, is arranged in a discharge vessel of the lamp and in particular is fastened, for example, to an electrode frame.
  • the carrier element is surface-coated and has, on the one hand, a coating with an Hg-containing material and, on the other hand, a coating with a getter material.
  • the two coatings are separated from each other.
  • the support member may be a substantially flat plate or even an angled formed plate.
  • a carrier element which has the features according to claim 1
  • a discharge lamp which has the features according to claim 15.
  • An inventive carrier element is designed for mounting in a discharge lamp.
  • a Hg-containing material is arranged on the support element.
  • This Hg-containing material is formed as a rod-shaped element and arranged on a holder of the carrier element.
  • the rod-shaped element is designed such that it has a defined amount of mercury per unit length and the amount of mercury to be attached to the carrier element can be metered depending on the length of the element.
  • the mercury concentration can be adjusted and reconstructed in a very simple and quickly reproducible manner, since only a desired length of the element has to be used in order to be able to provide the carrier element with a desired mercury concentration.
  • the carrier element has at least one recess as a holder, in which the element is arranged is.
  • a recess for example, a groove or a trench or even a blind hole-like formed may be provided.
  • the support member is plate-like and formed the recess in this plate-like part.
  • the retaining tab extends substantially over the entire length of the rod-shaped element.
  • the rod-shaped element is arranged in the interior of the retaining tab, wherein the retaining tab substantially peripherally surrounds the rod-shaped element substantially completely.
  • the rod-shaped element can also be protected.
  • the tubular hollow body surrounds an electrode arranged in the discharge vessel of the discharge lamp.
  • a carrier element which is also referred to as a cap, is arranged such that the axis of rotation or longitudinal axis of the hollow body is arranged parallel or coaxial to the longitudinal axis of the electrode.
  • Such a carrier element is designed to be multifunctional.
  • the carrier element is arranged on a power supply for an electrode.
  • This power supply is associated with an electrode frame and serves to hold the electrode in the discharge space.
  • the carrier element is arranged on an electrode frame associated central support, which is designed to hold a tube-like hollow body surrounding the electrode.
  • the support element is thus not at the same time also the tubular hollow body, but a separate component part, which is arranged on the central support.
  • the rod-shaped element has a jacket and a core, wherein the mercury is contained exclusively in the soul.
  • the mercury in the rod-shaped element is thus enveloped by the jacket material.
  • the metered amount of powdery mercury material in the interior (in the soul) of the rod-shaped element, in particular of the wire, is reproducible, very accurate and in particular only dependent on the length. In particular, dosing quantities of less than 1 mg can be realized very precisely.
  • the electrode frame 3 has two separate power supply lines 8 and 9, which are provided for holding an electrode 10 designed as a lamp filament.
  • a carrier element 11 is arranged in the discharge space 5 of the discharge lamp 1.
  • the support member 11 is in the embodiment shown according to Fig. 1 attached to the power supply 8.
  • the carrier element 11 is in Fig. 1 shown schematically.
  • At least one elongate element 12, in which Hg-containing material is arranged, is formed on the carrier element 11.
  • the support element 11 may also have a plurality of such rod-shaped elements 12, which may be geometrically the same or different.
  • the Carrier element 11 is designed as a metal band and formed in a first approximation plate-like.
  • the support member 11 at the same time represent this cap.
  • the cap is in particular arranged positionally accurate with a rod-shaped central support (not shown), this center support being assigned to the electrode frame 3 as an additional component to the power supply lines 8 and 9. It can also be provided that the carrier element 11 is attached to said central support on which the cap is arranged.
  • the support member 11 is designed as a plate-like metal strip and formed as a piece of wire elongated element 12, which comprises both Hg-containing material and getter, arranged in the support member 11.
  • the support member 11 can gluing or welding be provided of the support member 11.
  • an embodiment of the support member 11, as explained in the following FIGS. 5 and 6 is shown provided.
  • the carrier element 11 according to the illustrations in Fig. 2a and 2b In addition to the function of the holder of the rod-shaped element 12, it is also provided for encompassing the electrode 10.
  • Fig. 4a is a perspective view of another embodiment of the support member 11 shown as a tubular hollow body.
  • the rod-shaped element 12 has a smaller length than the height h1.
  • retaining tabs 16 and 17 are provided, which are cap-like over the ends of the rod-shaped element 12 slipped.
  • the retaining tabs 16 and 17 are thus arranged virtually like a cover over the upper and lower ends of the rod-shaped element 12. Slipping out can be particularly well prevented.
  • a further attachment in the form of gluing or welding can also be provided.
  • Fig. 6 is shown in a perspective view of another embodiment, in contrast to the embodiment according to Fig. 5 the carrier element 11 is arranged with the rod-shaped element 12 approximately at the level of the center of the middle support 18 there. At the middle support 18, moreover, as already to Fig. 5 explained cap for grasping the electrode 10 attachable.
  • a further embodiment is shown in a perspective view, wherein the support member 11 is designed as an angled plate. At its front end, in turn, a recess 19 is designed in the form of a bend of the plate-like part, wherein the rod-shaped element 12 is arranged therein.
  • the central support 18 is provided in addition to holding the support member 11 for holding a previously explained cap.
  • Such a central support 18 is provided in addition to the power supply lines 8 and 9 and associated with the electrode frame 3.
  • Fig. 8 is shown in an exemplary representation of a support member 11 which comprises a plurality of rod-shaped elements 12. These are each arranged in a recess 19 of the plate-like support member 11 and spaced and positioned substantially parallel to each other. The length l of the elements 12 is substantially equal.
  • the elongated element 12 has a mercury concentration of 0.46 mg per millimeter in length and is formed as a wire.
  • Fig. 9 is shown in a perspective view of a welded to a power supply 8 support member 11.
  • the power supply 8 in this case runs essentially parallel to the element 12 and is arranged on the upper side of the carrier element laterally to the recess 19.
  • two welding points are provided for fastening, wherein this may also be several or an entire lengthwise welding may be formed.
