Definitions

  • the invention relates to an electric light bulb according to the preamble of patent claim 1.
  • Such an electric light bulb is disclosed, for example, in German Offenlegungsschrift DE 23 54 045.
  • This lamp has a lamp bulb sealed on one side, in the interior of which there is a filament.
  • the two ends of the filament are each electrically conductively connected to a power supply lead out of the sealed lamp bulb end.
  • the two power supplies are melted into a glass or ceramic bead.
  • the power supply lines and the fusible pearl form the lamp frame supporting the incandescent filament.
  • the fusible link divides the two power supplies into a section near the helix and a section away from the helix.
  • the sections of the two power supply lines near the helix and away from the helix as well as the incandescent filament lie in the same plane.
  • this lamp does not have sufficient vibration resistance perpendicular to the plane spanned by the power supply lines and the incandescent filament.
  • the lamp is therefore only suitable to a limited extent for use in a motor vehicle.
  • the incandescent filament is carried by two current leads which are melted into a melting bead made of glass or ceramic. These power leads are each connected to one end of the filament and led out of the sealed lamp bulb ends.
  • the fusible link divides the two power supplies into a section near the helix and a section away from the helix. The section of the power supply line near the helix extends from the fusible link to the incandescent filament and the section remote from the helix runs between the fusible link and the sealed end of the lamp bulb.
  • the power supply lines are designed in such a way that their sections close to the helix lie in a first common plane, which are arranged approximately perpendicular to a second plane, which is defined by the power supply sections remote from the helix.
  • This measure improves the vibration resistance of the lamp perpendicular to the filament axis in a simple manner.
  • the invention can be applied particularly advantageously to electric light bulbs which are used in motor vehicles, for example as brake lights, rear lights or turn signals.
  • the lamp shown in FIGS. 1 and 2 is an electric incandescent lamp for use as a taillight or flashing light in a motor vehicle.
  • This lamp is powered by the voltage source of the motor vehicle and has an operating voltage of typically 12V or 24V and an electrical power consumption of approx. 21W.
  • the lamp according to the invention has a lamp bulb 1 made of glass and a bayonet base 2, in which the sealed end (not shown) of the lamp bulb 1 is cemented. In the interior of the lamp bulb 1 there is a filament 3, the ends of which are each connected to a power supply 4, 5 in an electrically conductive manner.
  • the electrical power supply lines 4, 5 are led out of the sealed end of the lamp bulb 1 and establish an electrical connection between the incandescent filament 3 and the electrical contacts of the bayonet base 2.
  • the power supply lines 4, 5 are fixed in a melting bead 6 made of glass and serve to hold the incandescent filament 3 inside the lamp bulb 1.
  • the melting bead 6 divides the two power supply lines 4, 5 into a 4a, 5a and a 4b, 5b near the spiral Section.
  • the current supply sections 4a, 5a close to the spiral extend from the melting bead 6 to the incandescent filament 3, while the sections 4b, 5b of the current supply lines 4, 5 remote from the spiral extend between the melting pearl 6 and the sealed end of the lamp bulb 1 cemented in the bayonet base 2.
  • the current supply sections 4a, 5a near the helix lie in a common plane in which the axis of the filament 3 is also arranged.
  • the sections 4b, 5b of the power supply lines 4, 5 which are remote from the helix also lie in common Level.
  • these two planes, which are defined by the 4b, 5b or the 4a, 5a current supply sections near the spiral are oriented approximately perpendicular to one another.
  • the frame 4, 5, 6, which is prefabricated from the melt bead 6 and the power supply lines 4, 5 melted therein and serves to hold the incandescent filament 3, is twisted above or below the melt bead 6 by an angle of approximately 90 °.
  • This measure according to the invention increases the vibration resistance of the lamp perpendicular to the filament axis.
