Definitions

  • the invention relates to a double-ended electric lamp according to the preamble of claim 1.
  • These are in particular metal halide lamps, but also other types of high-pressure discharge lamps or halogen incandescent lamps.
  • the double-ended lamp according to the invention has a vacuum-sealed, elongated piston defining a longitudinal axis and which is closed at opposite ends by sealing members, each having a base attached to one end of the sealing member.
  • the base has an electrical contact element, which is electrically conductively connected to a power supply leading to a light source in the interior of the lamp.
  • the contact element is anchored together with an adjusting part in a tubular region, in particular in a tubular extension, of the sealing part.
  • the adjusting part which is directed from the contact element towards the lamp interior, is connected to the contact element. It has at least one outwardly projecting, self-aligning centering member in contact with the tubular extension. By contacting the adjustment of the contact element is achieved.
  • the adjusting part is thus arranged between the contact element and the lamp interior.
  • the present invention is a vacuum-sealed, elongated piston which defines a longitudinal axis and in which a light source is located, wherein the piston is closed at opposite ends by sealing members.
  • a base is attached to a sealing part, wherein the base has an electrical contact element, which is connected to a leading to the light source power supply electrically conductive via an adjusting part.
  • the contact element is housed in a tubular part of the sealing part, in particular a region or an extension.
  • To the contact element directed towards the lamp interior adjustment part is attached, which is equipped with an outwardly projecting and self-adjusting centering, here called boom, which is in contact with the tubular extension or area.
  • the boom is provided with a spring action, and in particular for the purpose of self-adjustment of a tilting movement more accessible boom, which is mounted laterally and spaced from the axis of the lamp on the adjusting part.
  • the adjusting part has two approximately axially parallel rail sections, which, together with the centering part, permit a three-point bearing, seen in cross-section.
  • the support points of the rail pieces are arranged on the other side of the axis.
  • the adjusting part has at least one, preferably two sockets or recesses for holding the power supply. With two sockets, the stability of the connection is higher and the orientation of the power supply can be set more accurately.
  • contact element Most of the contact element is shaped like a disk. It can be bulged plate-like for better contact to the outside to the socket out.
  • the adjusting part may preferably have two side walls which are aligned axially parallel and which are connected to each other via at least one, preferably two, bridge parts.
  • the rail pieces can in particular each represent narrow sides of the side walls.
  • Expedient and space saving one or each socket is attached via an extension part to a bridge part.
  • the boom is a slightly outwardly of the axis inclined arm made of spring steel, which is in particular formed integrally with the rest of the adjusting part. He either pushes against the surrounding wall of the tubular extension, or he is in the surrounding wall of the tubular extension, which is a sleeve, melted.
  • the free tip of the cantilever has a reduced inclination compared to the arm itself. This facilitates insertion of the adjustment member into the tubular portion. This creates a kind of joint that facilitates self-centering.
  • the inclination of the arm is 5 ° to 20 ° to the lamp axis, so that the adjustment can be easily inserted into the tubular extension, the boom is ultimately under tension and so a holder causes, which can still be improved by a boom associated with the depth.
  • the groove sits in the tubular area.
  • the tip of the arm is bent back to the axis at the free end of the arm to avoid damage to the surrounding tubular area during insertion of the adjusting part.
  • each rail piece preferably consists of at least two axially successive sections of the side wall.
  • the shape of the rail pieces is such that the edge slope of the two sections against the axis is about 3 to 20 ° and differs from each other by at least 2 °, preferably by about 5 to 15 °.
  • the sections are roof-like, in that the edge inclination is in principle directed oppositely, in particular, it can be symmetrical.
  • At least one further section He is inserted between the first two sections.
  • it can be aligned parallel to the axis, but it does not have to.
  • the edge inclination between the two end points which in this special case virtually represent the first two sections, can change continuously.
  • An optimal interaction between rail section and boom is achieved when the axially parallel portion of the rail section is arranged at approximately the same distance from the lamp or center of the lamp as the intermediate piece of the boom.
  • intermediate piece is meant the interface between the two differently inclined parts of the cantilever.
  • the two rail pieces may also have different individual edge slopes of their two sections.
  • adjusting part and contact element are made of one piece, usually stainless steel, tungsten or molybdenum or another conductive metal used as a material. It can also be composed of two or three parts.
  • the above concept is suitable for many types of lamps, in particular for discharge lamps or incandescent lamps. It is particularly preferred in lamps with an outer bulb. In this case, the outer bulb, the discharge vessel completely or partially surrounded.
  • the lamp shafts may be bruising or melting.
  • the contact element is shaped like a disk, usually as a circular disk or oval with a smooth or serrated edge.
  • the base comprises an adjustment part made of spring steel.
  • a particular advantage of the invention is that it allows to set the tolerances in the production. While conventional techniques, see DE-Az 103 25 553.2, require a high accuracy in the manufacture of the component of typically 2/100 mm, the component according to the invention requires only an accuracy of 2/10 mm due to its self-centering. the component acting like a clip slips into the sleeve by itself after the ice netting in the correct position.
  • a stiffening of the whole construction is achieved by the contact element is connected both directly to the power supply, as well as the centering element.
  • a typical application is metal halide lamps and halogen bulbs with and without outer bulb.
  • Figure 1 shows the side view of a two-sided pinched halogen incandescent lamp. It consists of a cylindrical piston 1, in which a luminous body 2 is arranged axially and a halogen-containing filling is introduced. The luminous element is held in the piston 1 by knobs 10.
  • the luminous element 2 consists of luminous sections 3 with a small pitch, which are separated by non-luminous sections 4 of great pitch.
  • the ends 5 of the filament are embedded in their function as an internal power supply directly into the pinch 6 and connected there with a molybdenum foil 7.
  • an extension in the form of a tubular glass sleeve 11 is externally formed.
  • the sleeve 11 is narrower than the broad side of the pinch 6, but wider than the narrow side of the pinch. 6
  • a base part 8 is clamped, which is shown only schematically and which is made of sheet steel (V2A) or spring steel sheet with a thickness of 0.4 mm.
  • a molybdenum wire with a diameter of 0.6 mm is arranged as an external power supply 15, which is welded to the base part 8.
  • FIG. 2 Another embodiment of a metal halide lamp is shown in FIG. 2.
  • the quartz glass discharge vessel designed as a barrel body 9 includes two electrodes 12 together with a metal halide filling.
  • the piston ends are sealed by pinches 6, are embedded in the films 7.
  • the outer power supply 15 is guided in a tubular sleeve 11, which here represents an extension of the discharge vessel, and ends in the schematically illustrated base part 8.
  • the base is made in one piece from steel and also comprises a circular disk 13 as a contact element.
  • the bulbous part of the discharge vessel is surrounded by an outer bulb 16 which is rolled up in the region of the transition between the pinch 6 and the sleeve 11 (17).
  • the base 8 comprises a plate-like contact element 13, whose lower edge is attached to the outer power supply 15 via an adjusting part 21.
  • the adjusting part 21 is integral with the contact element 13. It is made of spring steel designed so that it is particularly stable, vibration resistant and above all self-centering.
  • the adjusting part 21 has a base part with two rail pieces 22 (only one is visible in section), which act as sidewalls, which run parallel to the outer power supply 15.
  • two bridge parts 24a, 24b In a transverse plane lie two bridge parts 24a, 24b.
  • the bridge parts 24 connect the two rail pieces 22, 23 each near their ends.
  • the power supply 15 is mounted in two open-topped sockets 25, which branch off from the bridge parts 24 via two extension parts 26. They are connected to them, for example by soldering or welding.
  • a boom 27 is attached, and directed opposite to the socket-carrying extension member 26.
  • This boom 27 consists of a slightly outwardly inclined against the lamp axis long arm 28 to which a short free tip 29 connects, which in turn is slightly inclined to the axis of the lamp back.
  • This boom 27 accomplishes the self-centering together with the rail pieces 22, 23, since it presses against the sleeve 11 and the adjusting member 21 tilts so that it adjusts the power supply axis parallel.
  • the narrow sides 30 of the rail sections 22 serve as an abutment for a three-point bearing. These are designed so that they abut punctually on the wall of the sleeve 11 inside.
  • FIG. 3 shows a variant in which each rail section 22 consists of three sections.
  • the middle section 31 is aligned parallel to the axis, while the front (32) and rear (33) sections are inclined.
  • the contact element 13 adjacent rear portion 33 is less inclined than the opposing sloping front portion 32.
  • the contact element 13 is spaced along its circumference from the sleeve 11 or at most in purely mechanical contact with it, so that no Glasverformungsvon is needed. This has the positive effect that can be used for the contact element 13 cheap, not adapted to the glass material such as steel.
  • Figure 4 various shapes for the rail section 22 are shown.
  • Figure 4a shows a rail piece of only two sections 32a and 33a, which have in principle opposite slope in the manner of a roof.
  • Figure 4b shows a rail piece of only two sections 32b and 33b, which have the same direction but different degrees of inclination in principle.
  • This edge inclination against the axis is usually about 3 to 20 °, wherein the edge inclination of adjacent sections each differ from each other by at least 2 °. In particular, it differs in adjacent sections by about 5 to 15 ° against each other.
  • Figure 4c shows a rail piece of three sections, wherein the middle (31 c) is parallel to the axis and the front (32c) and rear (33c) section have the same but opposite tendency.
  • Figure 4d shows a rail piece of three sections, the middle (31d) being inclined in the same direction but less inclined than the rear (33d) section, while the front (32d) section has opposite inclination.
  • Figure 4e shows a rail piece of four sections, the middle (31d) being paraxial, while the fourth section 34 is inclined in the same direction, but less inclined than the rear (32e) section, while the front (33e) section has opposite inclination.
  • Figure 4f shows a rail section 19 in which the different sections merge into one another in a continuous curvature.
  • the two rail sections 22, 23 have different edge inclinations and differently shaped sections.
  • FIG. 6 shows a plan view
  • FIG. 7 shows a perspective view
  • FIG. 8 shows a view from the rear. It can clearly be seen here that the narrow sides 30 of the rail sections 22, 23 over the diameter of the Contact piece 13 survive and thus mediate the mechanical contact in the sleeve together with the boom 27 in the sense of a three-point bearing.
  • FIG. 9 shows a further embodiment of the adjusting part 34 for the base with only one bridge part 35, a connecting part 36 and a bushing 37, which are each mounted approximately centrally on the rail piece 38.
  • the connection to the contact element 13 takes place here only via the rail pieces 38 on the end face 40, the power supply (not shown) is also performed in a bushing 39 on the plate bottom.
