Definitions

  • the invention relates to an electric lamp with a glass or quartz vessel squeezed on one side, wherein at least two sealing foils are embedded in the pinch, the outward ends of which lead to the socket contacts and external power leads leading to the inside with the inside of the vessel leading internal power supplies are connected.
  • a problem with such lamps is the alignment of the lamp parts attached to the inner power supply lines during the squeezing process. Since the sealing foils are usually thinner than 50 pm and thus have no stiffness, alignment of the outer power supply lines is only very incomplete with the inner power supply lines and thus transfer the lamp parts attached to it. Therefore, constructions connected to the lamp parts and supported against the inner wall of the envelope bulb are usually used. However, these constructions require considerably more work and costs and are not desirable because of the shading involved.
  • the aim of the invention is to achieve a precise alignment of the lamp parts attached to the inner power supply lines during the squeezing process by means of a simple and inexpensive device and at the same time to ensure a vacuum-tight squeeze in the area of the sealing film.
  • the electric lamp with the features mentioned in the preamble of the main claim is characterized in that short pieces of refractory metal, such as e.g. Tantalum, molybdenum or tungsten are attached, which run transverse to the inner power supply lines and lie in the plane determined by the pinch.
  • refractory metal such as e.g. Tantalum, molybdenum or tungsten
  • the metal pieces are attached to the inner power supply lines using a gauge before the crimping process. They prevent the inner power supply lines from being twisted or tilted due to the squeezing process, and thus enable precise alignment of the lamp parts attached to these inner power supply lines.
  • the metal pieces advantageously consist of wire or sheet metal of the same metal composition as the inner power supply lines and are welded to the latter. In the case of sheet metal, both circular or oval and rectangular shapes are conceivable.
  • the same material composition of the power supply and metal piece prevents stresses and cracks due to different expansion coefficients.
  • the metal pieces advantageously run at right angles to the inner power supply lines in order to ensure optimal alignment of the lamp parts held by the power supply lines.
  • the electric lamp can be a high-pressure discharge lamp, the squeezed vessel forming the outer bulb and the inner power supply lines being the electrical connections for a discharge vessel located in the outer bulb.
  • Exact alignment of the discharge vessel in the outer bulb is of great importance in this type of lamp, since these lamps are preferably used in lamps with reflectors. In order to obtain uniform illumination, it is necessary for the center of the lamp to be located in a precisely defined location in the lamp.
  • the squeezed vessel in the electric lamp can also form the discharge vessel directly, the internal current leads being the electrical connections for electrodes located in the discharge vessel.
  • the electric lamp according to the invention can also be a halogen incandescent lamp, the squeezed vessel forming the lamp bulb, and the internal power supply lines forming the electrical connections for an incandescent filament located in the lamp bulb.
  • the metal pieces welded to the inner power supply lead prevent twisting or tensioning of the filament and thus prevent premature failure of the filament.
  • the metal halide high-pressure discharge lamp 1 shown in FIG. 1 has a Discharge vessel 2, made of quartz glass, which is surrounded at a short distance by an outer bulb 3 - also made of quartz glass.
  • the tungsten electrodes 4, 5 are connected to the inner power supply wires 9, 10 of the outer bulb 3 via sealing foils 6, 7 made of molybdenum, which are embedded in the pinch 8 of the discharge vessel 2.
  • These wires 9, 10 consist of molybdenum and have a thickness of 0.5 mm.
  • a getter 11 made of a zirconium compound is also attached to a metal carrier 12 in a potential-free manner by means of a wire 13.
  • the inner power supply lines 9, 10 are further connected to the outer power supply lines 17, 18 - also made of molybdenum - via sealing foils 15, 16 made of molybdenum inserted into the pinch 14 of the outer bulb 3.
  • the metal halide discharge lamp 1 has a filling of NaJ, SnJ 2 , TIJ, Hg and Ar (burner volume 0.27 cm 3 ) and generates a luminous efficacy of approx. 65 Im / W with a power consumption of 70 W.
  • the tungsten filament 22 is pinched with the molybdenum foils 25, 26 by means of the inner power supply lines 23, 24 - likewise made of tungsten - which also represent the holders for the filament 22 27 of the lamp bulb 28 made of quartz glass.
  • the molybdenum foils 25, 26 are in turn connected to the electrical connection contacts of the lamp — not shown here — via external current leads 29, 30.
