Definitions

  • the invention relates to a double-ended lamp according to the preamble of claim 1. It is in particular metal halide lamps.
  • a lamp closed on two sides is already known from EP 780 883, two base parts having contact elements which are seated in tubular extensions at the end of bruises which effect the seal.
  • the contact elements extend transversely to the lamp axis and are encompassed by the tubular extensions as sleeves.
  • the attachment takes place along the circumference of the contact elements.
  • the disadvantage of this is that the contact elements easily tilt, so that they are no longer exactly transverse to the lamp axis and, moreover, the risk of breakage is relatively high.
  • the lamp sealed according to the invention has a longitudinally elongated bulb which is sealed in a vacuum-tight manner and which defines a longitudinal axis and which is closed at opposite ends by sealing parts, a base being attached in each case to one end of the sealing part.
  • the base has an electrical contact element which is connected in an electrically conductive manner to a power supply leading to a lamp in the interior of the lamp.
  • the contact element is anchored together with an adjusting part in a tubular extension of the sealing part.
  • the adjustment part which is directed towards the inside of the lamp, is connected to the contact element. It has at least two radially outward centering parts that are in contact with the tubular extension.
  • the contact is used either for holding or at least adjusting the contact element, preferably it serves both purposes.
  • the centering parts consist of several, in particular three to four, barbs. These are preferably distributed over the circumference of an adjustment part serving as an attachment part for the contact element.
  • Three barbs are preferably used, which are evenly distributed over the circumference of the attachment part. so they are spaced 120 ° apart. This ensures secure centering with low material costs.
  • the attachment part, barb and contact element are made from one piece, mostly stainless steel, tungsten or molybdenum as the material.
  • the barbs can also be made separately from another material, in particular a non-conductive material such as plastic or ceramic.
  • the extension part can have a socket for receiving the power supply.
  • the above concept is suitable for many types of lamps, in particular for discharge lamps or incandescent lamps. It is particularly preferred for lamps with an outer bulb.
  • the outer bulb can completely or partially surround the discharge vessel.
  • the lamp shafts can be crushed or melted down.
  • the barbs are preferably arranged obliquely to the lamp axis, so that they can be inserted more easily into the sleeve, and they preferably form an angle of 50 to 80 °, in particular 60 to 70 °, with the lamp axis.
  • the contact element is usually shaped like a disc, usually as a circular disc or oval with a smooth or serrated edge.
  • the barbs are advantageously spaced at least 2 mm, advantageously even 5 mm, from the contact element.
  • the base comprises an adjusting part made of spring plate. It consists of a base part that spans a plane and from which two differently designed centering parts protrude radially in opposite directions.
  • the first centering part is shaped like a W and protrudes along the base part from its plane.
  • the two turning points of the W touch the extension part of the sealing part, in particular at least one of the turning points even being melted into the extension part.
  • the second centering part also connects the contact element to the base part, which gives additional stability.
  • the base part can consist of two struts running laterally to the power supply, which are connected by at least one connecting bridge, also called a yoke. Two or even three connecting bridges in different levels are preferred. This further improves stability.
  • the power supply can be in contact with a part of the connecting bridges or can be firmly connected to it, which promotes the accuracy of the centering.
  • This aspect is further improved in that the first centering element has a free end that is bifurcated so that it can adjust itself on the power supply.
  • the whole construction is stiffened by the contact element being connected directly to the power supply as well as by a centering element.
  • a particularly preferred embodiment is a second centering part, which consists of two spaced centering elements. The farther apart they are, the more exact the centering is. A preferred minimum distance is given by twice the diameter of the contact element.
  • a typical application is metal halide lamps and incandescent halogen lamps.
  • FIG. 1 shows the side view of a halogen incandescent lamp pinched on both sides. It consists of a cylindrical bulb 1, in which a luminous element 2 is arranged axially. It is held in the piston 1 by knobs 10.
  • the luminous element 2 consists of luminous sections 3 with a small slope, which are separated from one another by non-luminous sections 4 with a large slope.
  • the ends 5 of the filament also consist of non-illuminating sections with a large slope.
  • the ends 5 are embedded directly in the squeeze 6 in their function as an internal power supply and are connected there with a squeeze film 7.
  • the end 8 of the film 7 facing the luminous element is bent inside the pinch 6, the luminous element end 5 being inserted into the bend 9 and thus making an electrical contact with the film 7 purely mechanically.
  • a tubular glass sleeve 11 with an outer diameter of 7 mm and an inner diameter of 5 mm is molded onto the outside of the pinch 6 as a base.
  • the sleeve 11 is about 7 mm long. It is thus narrower than the broad side of the pinch 6, but wider than the narrow side of the Pinch 6.
  • a disk-like contact element 13 which is made of steel sheet (V2A) with a thickness of 0.4 mm, is embedded in the sleeve 11 transversely to the lamp axis at a depth of 3 mm from the sleeve end. It is designed as a circular disc or cloverleaf-shaped (see FIG. 2), the maximum radius of the disc 13 (Rmax) being 2.7 mm and the minimum radius (Rmin) being 2.0 mm. The latter is reached on the floor by four troughs 16 each. The troughs 16 are punched out of the disk as concave arcs. The troughs 16 serve in particular as a grip aid for a holder by means of pliers.
  • a hollow neck part 14 is attached to the rear of the element 13. Between the film 7 and element 13, a molybdenum wire with a diameter of 0.6 mm is arranged as an external power supply 15, which is welded to the neck part 14.
  • Two opposing barbs 20 made of plastic or ceramic are fastened on the neck part by means of a ring 38, the tips of which are anchored in the sleeve 11.
  • the rings 38 with barbs 20 are shown in front view in FIG. 5a.
  • FIG. 3 shows further possible basic shapes for the contact element. Specifically, this is an elliptical shape 17 (FIG. 3a), a triangle-like shape 18 (FIG. 3b) and a square-like shape 19 (FIG. 3c).
  • the basic shape of the latter is a 0.5 mm thick disc which has a concave central bulge 27 with a diameter of 3 mm. The largest diameter of the disc is 5.4 mm, its smallest diameter is 5 mm. The corners of the triangle and quadrangle are rounded.
  • FIG. 4 shows a further exemplary embodiment of a metal halide lamp.
  • the quartz glass discharge vessel designed as a barrel body 30 includes two electrodes 31 in addition to a metal halide filling.
  • the piston ends are sealed by crushing 32, in which foils 33 are embedded.
  • the outer power supply 21 is in a tubular Guided sleeve 22, which here is an extension of the discharge vessel, and ends in a socket 23 of an integral base part 24.
  • the base is made in one piece from steel and also comprises a circular disk 25 as a contact element and four barbs 26 as centering and holder.
  • the bulbous part of the discharge vessel is surrounded by an outer bulb 27, which is rolled up in the area of the transition between the pinch 32 and the sleeve 22 (29).
  • the arrangement of the barbs 26 is shown in front view in FIG. 5b.
  • FIG. 5 c uses three barbs 39 which are evenly distributed around the circumference, as a result of which a secure centering is already achieved with minimal material expenditure.
  • the base part 34 comprises a plate-like contact element 13 with a diameter D, the center of which is directly attached to the outer power supply 15.
  • the adjustment part 35 is designed here from spring plate so that it acts in a particularly stable, vibration-resistant and centering manner.
  • the adjustment part 35 has a flat base part 36 similar to a slide. It is made up of two struts 36a, 36b, which run parallel to the external power supply 15, and a yoke 37 located in the same plane at one end of the parallel struts 36a, b. The yoke 37 connects the two struts 36a, 36b.
  • transverse walls 40 which are arranged at the two ends of the base part 36 perpendicular to the plane of the base part below the base part. They also act like a yoke that connects the two struts 36a, 36b, even if they are angled by 90 °.
  • the power supply line 15 lies on the side walls 41 of the transverse walls facing the base part 36 and can be connected to them, for example by soldering or welding.
  • the transverse wall 40 can also be a as shown Have recess 42 for partially receiving the power supply 15.
  • a first centering part 43 which extends radially outward, is attached centrally to the yoke 37.
  • a reversal point 48 which is oriented in the direction of the power supply 15, lies approximately in the middle between the two turning points.
  • centering is ensured by a second centering part, in that the two transverse walls 40, primarily their edges, act as centering elements.
  • An additional auxiliary centering element is preferably used, which attaches as a clip 49 to the second transverse wall 40 adjacent to the contact element, runs parallel to the plane of the struts and connects this second transverse wall 40 to the contact element 13.
  • the second centering part here consisting of three centering elements, extends in the opposite radial direction as the first centering part. It touches the inner wall of the sleeve 14, see FIG. 7. It is important for exact centering that the second centering element 40 is spaced as far as possible from the first centering element, in particular by at least twice the diameter of the contact element 13.
  • the contact element 13 is advantageously slightly spaced along its circumference from the sleeve 14 or at most in purely mechanical contact with it, so that no glass deformation process is required. This has the positive effect that inexpensive material such as steel can be used for the contact element 13.
  • the contact element 13 is particularly double Stiffening via the power supply 15 and the clip 49 sufficiently stabilized.
  • the base part 34 thus remains gas-permeable overall.
  • FIG. 8 An overall view of the lamp 51 is shown in FIG. 8.
  • the base part 34 is wedged mechanically in the neck part 14.
  • transverse walls 40 and / or the clasp 49 can also have additional bent tabs for further support and stabilization.
