Definitions

  • the invention relates to a halogen incandescent lamp according to the preamble of claim 1 and a method for their preparation according to claim 9.
  • Such a mini mains voltage halogen lamp is described for example on the Internet domain www.osram.de under the product name "OSRAM HALOPIN®". With this halogen bulb, the nubble technique is used to obtain a robust lamp. Due to the small size and the possibility of use without protective cover, this mini mains voltage halogen lamp enables filigree, simply constructed halogen lights.
  • the Noppentechnologie is in the European Patent EP 0446 460 B1 described in detail.
  • the invention has for its object to provide a halogen incandescent lamp in which the light output is increased with the same life, and to provide a method for their preparation.
  • the electric incandescent lamp according to the invention has a lamp vessel which is sealed on one side and in which at least one luminous element is accommodated and which has two substantially rotationally symmetrical lamp vessel molded parts.
  • Each of the lamp vessel moldings engages at least in sections a luminous element leg and the axes of the lamp vessel moldings are formed spaced apart from each other.
  • At least one wall surface of the lamp vessel moldings is at least partially provided with an IR radiation reflecting layer, whereby the IRC effect is improved in the incandescent lamp and thus less energy must be supplied from the outside to bring the filament to operating temperature.
  • the lamp vessel moldings intersect.
  • the overall size of the electric bulb can be reduced.
  • An improvement in the production and with respect to a more uniform reflection on the luminous element can be implemented by a substantially cylindrical design of the lamp vessel moldings.
  • a robust lamp construction can be achieved by the use of holding nubs directly in the lamp bulb, whereby a long service life is ensured even under mechanical stress of the lamp.
  • the use of the present invention is not limited to the Quetschnoppentechnik, but the above-mentioned embodiment of the lamp vessel moldings is also applicable to luminaires, which are fixed in position by a holder frame, applicable.
  • the axial course of the luminous element limbs in the lamp vessel shaped parts in particular the course of the luminous element limbs along the respective center axis of the lamp vessel shaped parts, advantageously has an effect.
  • the reflection of the heat on the filament is thus at an optimum value.
  • the deformation of the lamp vessel to form the two lamp vessel moldings is carried out simultaneously with the main squeezing, so that a short production time is obtained.
  • the application of the IR radiation-reflecting layer is preferably carried out after the deformation of the lamp vessel, while the squeezing of the nubs is carried out before the deformation. In this way, an energy-optimized light bulb can be effectively produced.
  • Figures 1 to 5 show a designed for operation on mains voltage halogen incandescent lamp 1. In principle, however, the invention is also applicable to NV or MV halogen incandescent lamps.
  • the halogen incandescent lamp 1 has, according to FIGS. 1, 2 and 4, a lamp vessel 2 which is preferably made of quartz glass and on the lower end portion of which is formed by a pinch seal in FIG. 1 a pedestal 4 which can be inserted into a socket (not shown).
  • This base 4 passes over a circumferential chamfer 6, which is also shown in Fig. 4, in a piston 8 of the lamp vessel 2 via.
  • the end portion of the lamp vessel 2 remote from the base 4 is formed by a dome 10 on which a pump stem extension 12 is formed.
  • a luminous body 14 is arranged, which is in the described embodiment with two filament legs 16, 18, on which the coil sections 16a, 18a are located, which are connected via a connecting part 20 with each other.
  • the luminous body limbs 16, 18 run essentially parallel to one another.
  • the two filament legs 16, 18 go into power supply lines 22, 24, the end portions of which dip into the base 4 formed by the pinch seal and each having a molybdenum foil shown in Fig. 1 26, 28 are connected, which are also embedded in the base 4.
  • These molybdenum foils 26, 28 are in turn connected to approximately U-shaped outer power supply lines, referred to below as contacts 30, 32, whose bent-back end sections are immersed in channels of the base 4 or embedded in them.
  • the filament legs 16, 18, the connecting part 20 and the two power supply lines 22, 24 are preferably made of tungsten.
  • holding lugs 34, 36 are formed on the lamp vessel 2 approximately at the level of the connecting part 20, which in the illustration according to FIG. 2 are arranged perpendicular to the plane of the drawing and which extend in the illustration according to FIG. 3 in the vertical direction and in FIG. 4 parallel to the plane of the drawing.
  • the piston 8, following the circumferential chamfer 6 on two intersecting cylindrical piston mold parts 42, 44, along the central axes of the luminescent body legs 16, 18 are arranged.
  • the intersecting, cylindrical piston mold parts 42, 44 form in the sectional view of Fig. 5 along the line AA of Fig. 2 is substantially in the form of a figure eight.
  • the cylindrical piston mold parts 42, 44 pass into the dome 10 by means of a transition region 40, in which the holding nubs 34, 36 described above are formed. Of the Transition region 40 takes on the shape of the intersecting cylinder of the piston mold parts 42, 44 and passes them over to the circular shape in the exemplary embodiment 10 dome.
  • an infrared coating (I nfra- R ed- C oating) is in the range of the cylindrical piston shape parts 42, is applied, through which the heat to the luminous element limbs 16, is reflected back 18th By such reflection, the heat remains in the lamp and it must be supplied less energy from the outside to bring the filament legs 16, 18 to temperature.
  • the holding nubs 34, 36 are each formed with an approximately elliptical cross-section, the longitudinal axis of which covers the region 38 of the connecting part 20 arranged horizontally in FIG. 2 in order to achieve a maximum connecting area between the elliptical end faces of the holding nubs 34, 36 and the connecting part 20.
  • the holding nubs 34, 36 are squeezed in order to hold the luminous body 14.
  • the piston 8 is deformed so that the two intersecting piston mold parts 42, 44 are obtained, wherein the luminescent body legs 16, 18 extend with the helixes axially to a respective piston mold part 42, 44.
  • the main pinching takes place, in which the base 4 is formed.
  • a pumping tube is attached to the pumping stem approach 12, through which the interior of the piston 8 is evacuated and filled with a filling gas containing halogens.
  • the high light output due to the infrared coating is supported by a xenon gas filling.
  • the pump tube is removed and sealed to the pump stem approach 12.
  • the application of the present invention is not limited to incandescent lamps with holding nubs, but the rotationally symmetrical, preferably cylindrical Design of the lamp vessel moldings 42, 44 is also applicable to other lamps, such as lamps with holder frame.
  • the luminous body limbs 16, 18 preferably extend along the central axis of the lamp vessel shaped parts 42, 44. An improvement in the luminous efficacy can also be observed with a course of the luminous body limbs 16, 18 which is substantially parallel to the central axis of the lamp vessel moldings.
  • the lamp vessel moldings 42, 44 have the same outer diameter, but also different outer diameters of the lamp vessel moldings 42, 44 can be implemented and the outer diameter of the respective lamp vessel moldings 42, 44 can vary over its axial extent, such as eg in the form of a frustoconical design.
  • the present invention relates to an electric incandescent lamp, in particular a halogen incandescent lamp, in which luminous element legs extend in lamp vessel shaped parts, wherein the lamp vessel shaped parts engage around the luminous element sections at intervals and the axes of the lamp vessel shaped parts extend at a distance from one another, in order to increase the energy efficiency of the incandescent lamp to increase, in particular when applied to the lamp vessel moldings, an IR radiation reflective layer is applied.
  • a small mains voltage halogen lamp with a long life expectancy at the same time low energy to achieve the operating temperature can be implemented.
