Definitions
- the invention relates to a low-pressure mercury discharge lamp the preamble of claim 1.
- the mercury is either introduced into the lamp in liquid or solid form, in particular as amalgam.
- the amalgam lamps can be of different designs to have. For example, it can involve conventional fluorescent lamps act as a rod-shaped discharge vessel, or also compact fluorescent lamps with bent tubes, e.g. B. U-shaped or H-shaped, or spherical, electrodeless, low-pressure discharge lamps.
- Such compact fluorescent lamps are for example from EP-A 373 567 known.
- the amalgam is introduced into the pump tube, the discharge-side opening is slightly narrowed.
- the pump tube themselves have a narrowing, see e.g. EP-A 161 725.
- a spherical electrodeless low-pressure discharge lamp is for example known from EP-B 119 666.
- the main amalgam is in one introduced like a hollow.
- a variant of this lamp is in "News from the technology" No. 1/86 described, the main amalgam is in a closed pump stem, the top of which is one has slight asymmetrical narrowing. This is said to be avoided that the amalgam gets into the flask and the phosphor layer or damage other parts, or not the corresponding working temperature reached.
- the present invention adopts the basic technologies of EP-A 581 160 and EP-A 228 005, the contents of which are hereby expressly stated is referenced.
- the latter describes a storage element for dosing and introducing mercury as liquid metal or liquid or solid amalgam, the storage element being formed by a porous pressed body, especially of iron.
- the former describes a fixed one Amalgam body or amalgam former body with a ferromagnetic Component.
- a quick pumping and filling with safe retention of the Mercury is used in a low-pressure mercury discharge lamp a pump tube attached to the discharge vessel, the outer end of which is melted and the inner discharge end is open, thereby achieved that the mercury (Hg) metallic or as amalgam (im hereinafter generally referred to as Hg body) in the pump tube is.
- the discharge-side opening of the pump tube is narrowed.
- a solid is introduced into the pump tube so that it the opening of the pump tube as a plug for the mercury body partially closes.
- the solid body can preferably be made of ferromagnetic material (especially iron) so that it turns on during the pumping and filling process can be held anywhere in the pump nozzle by means of a magnet can. This has proven to be even more economical than that Proven use of a ferromagnetic amalgam (former) body, which, however, is not excluded.
- ferromagnetic material especially iron
- the solid body can be spherical, ellipsoidal or irregular be designed, the pump opening being a different one Shape, in particular an asymmetrical shape.
- the solid forms at least approximately a circular cylinder (e.g. rounded exactly or in tablet form or slightly elliptically distorted) with assigned diameter and assigned height.
- Good results can be achieved if the diameter of the solid between 50 and 90%, in particular 60 and 80%, of Corresponds to the inner diameter of the pump tube, so that there is enough space between Solid and pump tube wall remains.
- the height of the solid be smaller than its diameter, in particular it should correspond to about 50 to 80% of the diameter of the solid. This According to experience, dimension is particularly favorable for a smooth Function of the filling process with regard to a randomly changing Orientation of the solid in the pump tube. Tilting or damage is minimized.
- the solid can flow freely in the pump tube rotate.
- a Embodiment may open the pump tube with a circular solid (Ball or circular cylinder) should not be circular, but should define a largest longitudinal and transverse dimension, with the longitudinal dimension is larger than the transverse dimension.
- the geometric dimensions to be selected serve in the case of a circular cylindrical solid that either the largest transverse dimension larger, in particular 0.1 to 0.4 mm larger than the height of the solid is or that the largest longitudinal dimension is larger than the diameter of the solid.
- Advantageous if only one is observed of these conditions is that the narrowing of the opening extends beyond a certain Height (typically 1 to 2 mm) extends. Because of the different Even in this case, the solid can never have the shape of the opening Close the opening completely. Ideally, both conditions are met at the same time.
- the largest transverse dimension of the opening is particularly advantageously smaller than the diameter of the solid.
- the opening can preferably be an elliptical or have a crescent-like cross-section. It can also be similar to one "8" or crescent-shaped. It can be any asymmetrical Have shape.
- the opening does not matter whether the opening is attached centrally or decentrally with respect to the pump tube, however a decentralized, especially close to the edge, cheaper opening because it leaves more design options for the opening and makes it easier allows the narrowing to be greater in both the longitudinal and transverse directions than the height and diameter of the solid. The reason is that because of the close wall of the pump tube, the opening and the solid do not get the best possible coverage.
- the optimal range is one Axis ratio of the narrowing between 1.1 and 2.0, the (shorter) Cross dimension should be greater than 1.0 mm so as not to impede diffusion.
- the circular opening of the pump tube leave.
- the effective cross section is narrowed by the fact that a piece of wire or similar spanned the opening transversely and thus as a barrier works.
- the foam is at least partially open-pored, to allow diffusion of mercury into the discharge vessel.
- the foam can also be a contain a high proportion of closed pores, but the opening does not is completely closed by the glass foam plug, but one The remaining opening for the diffusion of mercury remains.
- the solid not only as a plug, but also as a sponge for the mercury body Act.
- the solid forms a porous one Matrix as a basic body, which contains liquid mercury or contains liquid amalgam.
- one for the formation of the Amalgam's cheaper amalgam partner in liquid or solid form behind be introduced into the solid.
- amalgam can also be used, which is solid at room temperature.
- the solid is filled into the pump tube first and only then Amalgam, so that the latter with respect to the discharge-side pump opening lies behind the solid.
- the nature of the solid plays no role, but still its geometric dimensions.
- FIG. 1 shows a discharge vessel 1 for a compact fluorescent lamp, the Is bent into a U-shape. It has two ends 2a, 2b in which electrodes (not visible) are squeezed. One end 2a is in the middle with a pump tube 3 equipped, the discharge-side narrowed end 4 in the discharge vessel 1 protrudes while the distal circular end 5 is accessible from the outside.
- a pump connector 9 and a seal 9a are initially both pump ends 4, 5 open.
- a solid 6, which consists of iron, is through one Magnet 7 held in the middle of the pump nozzle 9. Behind it is a fluid one or solid amalgam (or liquid mercury) 8 into the pump tube brought in. After filling the discharge vessel with inert gas, the Magnet 7 removed so that the solid 6 and the amalgam 8 (or Hg) slide to the discharge end 4 of the pump tube. Then will the end of the pump tube remote from the discharge was shortened and melted.
- FIG. 2 shows an enlarged illustration of the squeezing area 2a.
- the Discharge-side pump tube end 4 is narrowed, so that the solid 6 Opening blocked despite orientation oriented and that Amalgam 8 prevents it from escaping into the discharge space. That far from discharge Pump end 5 'has melted.
- FIG 3a shows that the solid body 6 shown here transversely and the pump opening 4 are coordinated.
- the pump tube 3 has an inner diameter of about 2.5 mm and a wall thickness of 0.75 mm.
- the Pump opening 4 is arranged elliptically and centrally with respect to the pump tube 3.
- the largest longitudinal dimension is about 1.70 mm (corresponding to the Double the major semiaxis), the largest transverse dimension (accordingly double the small semiaxis) is about 1.4 mm.
- the solid is a circular cylinder with a diameter of 1.8 mm and a height of 1.2 mm.
- the Formation of the opening extends over a height h of approximately 1.6 mm (Fig. 2). Due to the different shape of the opening, the solid can Do not close the opening even if it is lying crosswise.
- FIG. 3b shows the case mirrored to Fig. 3a, that the longitudinal dimension the opening is larger than the diameter of the solid.
- Figure 3c shows the theoretical (because of the unimpeded diffusion) best case that the largest longitudinal or transverse dimension of the opening are larger than the diameter or the height of the solid. Indeed this opening is very difficult to make. A plasma torch is advantageous for this used.
- Such regular pump openings are produced by two opposite gas burners with different intensities are directed towards the originally circular opening of the pump tube.
- the melted glass contracts and forms a non-circular (here elliptical) opening.
- the pump opening is 10 decentrally arranged and asymmetrically shaped. It is partial again blocked by the solid body 11, which here is a porous compact with a circular cylindrical Shape is. It contains liquid mercury in its matrix.
- Fig. 5 shows that the pump opening 10 has a crescent shape.
- the inner diameter of the pump tube is 2.5 mm.
- the largest longitudinal dimension the opening is 2.5 mm, the largest transverse dimension is 1.5 mm.
- the compact has a diameter of 1.8 mm and a height of 1.2 mm.
- Such irregular pump openings are produced by a gas or plasma torch that is one-sided on the area of the original circular opening is directed to that of the later crescent Opening is opposite.
- FIG. 6 there is 15 behind the solid body a body 16 made of solid amalgam or solid amalgam partner.
- a body 16 made of solid amalgam or solid amalgam partner As is known per se, it consists of a bismuth / indium alloy in a ratio of approx. 2: 1 or a bismuth / lead / tin alloy.
- Other examples are alloys made of Bi-Pb or Bi-Pb-In or Bi-Pb-Ag. In addition, they each contain a few percent mercury. It with regard to the amalgams used, for example, on EP-A 373 567, EP-A 327 346, DE-OS 35 10 156, EP-A 157 440 and US-A 4 093 889 referenced.
- FIG. 7a schematically shows the top view of a pump opening 20 with a crescent shape Shape
- Figure 7b is an "8" like shape of the pump opening 21 shown.
- the crosspiece 22 of the "8" is made of process engineering Reasons not fully trained.
- FIG. 8 shows the top view of a pump opening 25 with a circular shape, wherein a piece of wire 26 transversely narrows the opening 25.
- Figure 9a shows the top view of a pump opening 30 with a circular Shape, with a glass foam plug 31 completely closes the opening 30.
- the foam consists of open pores.
- the thickness of the plug is, for example, on the order of about 2 to 10 mm.
- Figure 9b shows the top view of a pump opening 30 with a circular Shape, with a glass foam plug 35 partially opening (30%) closes. The remaining opening 40 allows sufficient diffusion even if the glass foam is mostly closed Pores.
