Definitions

  • the invention relates to a method for producing a cap tape for Discharge lamps according to the preamble of claim 1 and a method for producing a discharge lamp according to the preamble of the claim 8th.
  • This discharge lamp has a metallic ring cap, which consists of two metallic Ring sections exist, one section having a mercury-releasing function has no such function while the other metallic section Has.
  • the first-mentioned metallic section consists of a nickel-plated Iron carrier and from a mercury alloy, which from one on the Carrier applied mercury titanium alloy powder.
  • the mercury alloy is on one side, the inside of the ring section arranged while a getter on the other side, the outside of the Ring section is arranged.
  • the one to be placed in the discharge lamp The amount of mercury is determined by changing the length of the first section. So if the amount of mercury has to be increased, the length of the first-mentioned metallic section enlarged.
  • the ring cap of the known discharge lamp is therefore not in one piece formed, but consists of a plurality of components. hereby both the cost of making the ring cap and the Cost of manufacturing the discharge lamp.
  • the object of the invention based on a method of the type mentioned and a Specify a method for producing a discharge lamp, which is a less expensive Manufacturing enables.
  • the invention is associated with the advantage that from a given Length of the carrier tape used in the method according to the invention a large number of sections can be produced, each section being simpler Way in particular can be processed into a one-piece ring cap.
  • the width is in the method according to the invention carrier tape used about 12 to 55 mm. Assuming that for a ring cap with a 5 mm wide cap band can be provided a running meter of the carrier tape according to the inventive method Make 200 cap straps, so 199 cuts are required. in the State of the art, in which the carrier tape has a width of 5 to 7 mm, to let only 23 cap straps for a full ring cap circumference of 42 mm produce.
  • getters and mercury alloy is several times more expensive than the material. If one according to the invention transversely to the material application direction cuts and also coated on one side, is the production speed for a section (cap belt) at the same machine speed by factors (depending on the width BT, Figures 3, 4) higher.
  • JP-A-6.76796 is a low-pressure discharge lamp with a Mercury amalgam-coated cap tape is known, the amalgam coating extends to the side edge of the cap band.
  • US-A-3657589 is a method for producing a mercury releasing Getter device described.
  • the getter device is separated a portion of a material releasing the mercury coated carrier tape created.
  • the cap tape is moved by coating the carrier tape on one side with the at least one to be introduced into the discharge lamp Material, in particular with two materials, namely with a mercury alloy and getters.
  • this has the advantage that the coating of the two materials on the carrier tape at the same time can be done.
  • the ring cap shown in Fig. 1 for a discharge lamp consists of a two-part oval ring 30 made of a first metallic piece 31 and a second metallic piece 32.
  • the first metallic piece can be formed by a cap band, which is shown in Fig. 2.
  • FIG. 3 is an embodiment of a method according to the invention manufactured cap band shown.
  • a carrier tape 1 Metal band
  • the carrier tape 1 for example made of nickel-coated Sheet iron is made with a mercury alloy 2 and / or getter material 3 e.g. coated by rolling.
  • the width BB of the carrier tape 1 is chosen so that it is equal to the circumference of the respective ring cap Discharge lamp corresponds.
  • the cap band 4 produced by the method according to the invention can be formed by coating the carrier tape on one or both sides. Examples of these embodiments of the cap band are in the 3 and 4 are shown.
  • 3 shows a cap band, the carrier band 1 on one side with getter material 3 and on the other side with one Mercury alloy 2 is coated.
  • From the carrier tape 1 is across its longitudinal direction LB (which is usually the material application direction) Section 5 separated, which forms the cap band 4 for a discharge lamp.
  • the section 5 or the cap band 4 is BT over its entire width coated at least one material.
  • the cap band produced by the method according to the invention has for example a length LT in the range of approximately 12 to 55 mm.
  • the respective Length LT corresponds, as already described, to the extent of the respective Ring cap of the discharge lamp (e.g. 48 mm for a T8 low-pressure mercury vapor discharge lamp with a diameter of 8/8 inches).
  • Cap band is coated on one side. Getter material and the mercury alloy are therefore arranged on the same side of the cap band. This in Fig. 4 shown cap band has a width of 44 mm.
  • 3 and 4 is a section on the right side of the carrier tape 1 5 shown by 5 mm width.
  • the section width BT in the present case 5 mm, the amount of what is to be introduced into the discharge lamp by heating Materials (mercury alloy and / or getter) determined.
  • the amount of material to be applied per carrier tape length unit Material determined with a view to a possible fixed width BT of the cap band.
  • a cap band produced by the described method according to the invention is used to make a discharge lamp in such a way that it is inserted into and fixed in the discharge lamp.
  • this cap band has a length that is equal to the circumference a ring cap of the discharge lamp (e.g. 44 mm).
  • the width of the section or the cap band is e.g. 5 mm, this width depending of the material to be introduced into the discharge lamp becomes.
  • the carrier tape is thus coated in such a way that on a for a discharge lamp certain section of the carrier tape with a predetermined Width BT of e.g. 5 - 7 mm that for the discharge lamp Amount of the material or materials is applied.
  • the section may be bent into the predetermined shape, into the discharge lamp introduced and attached there.
  • a discharge lamp according to the invention thus has a cap band 4, as previously described or claimed.
  • the ring cap shown in Figure 5 consists exclusively of an inventive Cap band 4, which is welded at its ends, while the ring cap shown in Figure 6 from a cap band according to the invention and another band, with cap band 4 and more Band are welded together.
