Definitions

  • the invention relates to a method for producing an electric lamp with outer bulb according to the preamble of claim 1. It is in particular discharge lamps such as metal halide lamps, but also halogen incandescent lamps.
  • DE-A 195 21 972 discloses a method for producing a cap strip for discharge lamps, the cap strip being a carrier strip with a material to be introduced into the lamp, in particular mercury and / or getter material as a coating. This unit is often referred to as getter tape. Only the discharge vessel of a low-pressure mercury lamp is seen as an area of application for such getter and cap tapes. The getter or cap band is often fastened in the vicinity of an electrode, see also US Pat. No. 6,043,603.
  • halogen incandescent lamp with a getter in the outer bulb can be found in CA-A 1 310 058.
  • the manufacturing method according to the invention for an electric lamp with an outer bulb and an inner vessel relates primarily to metal halide lamps. However, it can also be a halogen incandescent lamp with an outer bulb.
  • An important point is that the outer bulb is attached directly to the inner vessel, so that no electrode systems for the outer bulb and no brackets for power supply through the outer bulb are required. There is no need for a frame.
  • a cementless base is sought, with no ceramic base parts.
  • the contact pieces of the base are also suitable as holders for the power supply lines.
  • Known pump stem techniques are radically dispensed with, both in the inner vessel and in the outer bulb.
  • Protective sleeves for the power supply in the outer bulb can be omitted. The same applies to the V-shaped loop on the power supply in the outer bulb required for expansion compensation.
  • Suitable methods for introducing a part of the contact zone are in particular squeezing, rolling or letting them fall due to the application of a pressure difference, possibly with additional rolling or squeezing.
  • a preferred embodiment is designed in such a way that the part of the contact zone to be closed lies at the level of the pump hole, so that the pump hole itself is closed in the process.
  • Another preferred embodiment consists in that the part of the contact zone to be closed lies within the height of the pump hole, so that the pump hole itself is not closed in the process.
  • the method can be applied in particular to lamps in which the inner vessel and the outer bulb each have a single opening.
  • the method can be applied in particular to lamps in which the inner vessel and the outer bulb each have an additional second opening.
  • either a new roll-up can be used, the area to be rolled-up advantageously having already been reduced to a significantly smaller diameter in the first roll-up process.
  • the pump hole can also be closed by simply closing it after suitable heating using vacuum.
  • Another alternative is to create a vacuum or vacuum with subsequent squeezing or rolling. A proven technique of heating is done by a laser beam, or by plasma heating, or any other established method.
  • a typical application of the method is in metal halide lamps and incandescent halogen lamps.
  • FIG. 1 schematically shows the side view of a metal halide lamp 1 which is closed on both sides.
  • the discharge vessel 2 made of quartz glass and formed as a barrel body includes two electrodes 3 in addition to a metal halide filling.
  • the piston ends are sealed by melts 4, in which foils 5 are embedded. These are connected to external power supply lines 6.
  • the outer power supply 6 is guided in a tubular sleeve 7, which forms an extension part, and ends in a socket 8 of a base part 9.
  • the base part 9 is, for example, made in one piece from steel and also comprises a circular disk 10 as a contact element and barb 11 as a centering and Bracket.
  • the bulbous part of the discharge vessel is surrounded by an outer bulb 12 which is rolled up in the area of the transition between the melting point 4 and the sleeve 7 and forms a contact zone KO (13).
  • the outer bulb 12 has a circumferential dent 14 so that an elastic carrier band 15 made of stainless steel or nickel-plated iron is spread on the inner surface of the outer bulb without being able to slide sideways.
  • the carrier tape contains getter materials such as Zr, Fe, V, Co. They are used to absorb various substances such as oxygen, hydrogen, or the like.
  • the outer bulb can be filled with nitrogen, another inert gas or vacuum. in this embodiment, the contact zone KO lies completely against the inner vessel. In order to protect the power supply 6, as shown in FIG.
  • a film 19 can be attached to the rear end of the extension part, which is sealed by means of a pinch 21 '.
  • a production method is described as follows with reference to FIG. 2: the discharge vessel 2 is first completed so far from a cylindrical tube by means of a shaping roller and possibly crimping jaws, each of which fixes an electrode system introduced into the still open tube by squeezing both ends are provided with a seal (crushing or melting 4). At the same time, integral sleeve-shaped extension parts 7 remain on the seals 4. External power supplies and possibly base parts are located in the extension parts. It does not matter whether and how a base part is attached to the extension part. In the normal case, the base part is at most mechanically anchored, on both sides in the extension parts 7a and 7b.
  • a pump hole 18 is produced on the second extension part 7b in the vicinity of the sealing part, for example by means of a laser, which initially remains open.
  • the cylindrical outer bulb 12 is initially an open tube. It is first pretreated to the extent that a circumferential dent 14 laterally fixes a previously clamped-in carrier tape. The ends of the outer bulb are now brought up to the end of the sealing part and the beginning of the extension part 16 after being heated by flames. The first end is rolled up completely (arrow P1). At the second end, the diameter is reduced, but the entire contact zone KO is not brought into contact with the inner vessel. Instead, the fixation F is carried out by the suitably shaped roller R on the second extension part 16b outside the still open pump hole 18.
  • the outer piston 12 is rolled up, but not so that it rests on the extension part 16b (arrow P2 ).
  • This arrangement is on open end of the second extension part is connected via a feed line 38 to a pumping and filling system 39, in particular by placing a pump rubber 40 on the end of the extension part.
  • the pump path is shown as arrow P3.
  • the outer bulb 12 can then be charged with any inert atmosphere via this pump path or vacuum can be maintained.
  • the pump hole 18 is closed, for example, by either rolling it over locally over a short distance of the contact zone or simply by itself after local heating by means of a laser and applying negative pressure, see arrow P4 (FIG. 3).
  • FIG. 3 FIG.
  • FIG. 4 shows an exemplary embodiment in which the pump hole is closed by locally heating this zone and then mechanically pressing the region 50b of the extension part against the part 50a of the outer bulb that is brought in from the inside.
  • the end 16b of the second extension part normally always remains open. If necessary in the getter used, the getter band 15 can later be activated through the outer bulb 12 by means of a laser.
  • An alternative is that the pump hole remains open and instead the outer bulb is closed further inside, see Figure 5.
  • a narrow roller R2 is brought up to the inner end of the contact zone (arrow P5), so that approximately at height at the end of the film 5, contact is made with the inner vessel.
  • the pump hole 18 always remains open. In this way, optimal heat dissipation is achieved, which protects the film.
  • FIG. 6 shows a lamp similar to FIG. 1, a film 19 being attached to the end of the extension part.
  • the outer wall of the tubular extension part 7 at the level of the film is heated and squeezed (21 ') after the outer bulb has been closed.
  • the volume of the extension part is advantageously evacuated beforehand and possibly filled with inert gas. In this way, the corrosion of the external parts of the power supply can be delayed.
  • FIG. 7 shows an embodiment of a halogen incandescent lamp 41 which is closed on one side, in which a pear-shaped inner vessel 42 has a single opening 43 which is closed by a pinch as a sealing part.
  • the current feed-through system has two external power supply lines 44, which are connected via foils 45 a luminous element 46 are connected inside the inner vessel.
  • the outer power supply lines 44 are guided in a tubular extension part 47 which has a pump hole 48 on the side near the sealing area.
  • An outer bulb 50 surrounds the inner vessel, the sealing area and a short part of the extension part, typically 10 to a maximum of 35% thereof.
  • the end of the outer bulb is heated and brought up to the extension part 47, similar to that in FIG. 2.
  • the outermost end 49 is rolled onto or attached to the extension part, while the remaining area of the contact zone is only brought close to the extension part.
  • the pump hole is enclosed in the overlap area of the contact zone KO.
  • the volume of the outer bulb can then be evacuated via the pump hole 48 and filled if necessary.
  • the area of the pump hole is then heated with a laser, so that the contact zone falls automatically onto the pump hole by applying a negative pressure at the end of the extension part, similarly as described previously for double-sided lamps.
  • a laser a laser
  • the other methods previously described in detail are also suitable for this.
