Definitions

  • the invention relates to an electric incandescent lamp according to the preamble of patent claim 1.
  • Such an incandescent lamp is disclosed for example in the patent application DE 2105155.
  • This document describes a halogen incandescent lamp for projection purposes, the filament is connected to power supply lines, which are each surrounded by a support body. One end of this support body is embedded in each case in the sealed end of the lamp vessel.
  • the support bodies are formed as spirals. It has been found that with such support bodies sufficient vibration resistance for incandescent lamps, which are used in vehicle headlights, can be achieved.
  • the electric incandescent lamp according to the invention has an incandescent filament arranged within a light-transmitting lamp vessel and power supply lines for the incandescent filament, wherein at least one of the power supply lines is provided with at least one strut.
  • the at least one strut causes, in contrast to the trained as a helical support body according to the prior art, a stiffening of the power supply equipped with it. For example, curved or Angled power supply sections bridged by the at least one strut. This reduces the amplitude of the deflection of the filament from its equilibrium position and increases the vibration resistance of the incandescent lamp in the case of shocks.
  • incandescent lamps such as vehicle headlamps, which are equipped at one end with a base and in which the filament has a sockelnahen and a socket remote Wendelabgang
  • the socket remote filament outlet power supply is equipped with the at least one strut, as this power supply due its greater length has a lower vibration resistance.
  • the aforementioned power supply is equipped with a strut which is connected at at least three points with the socket remote power supply.
  • the at least one strut is connected to the at least one power supply at at least two points.
  • the at least one strut is preferably formed as a wire to keep the light shading caused by the strut within tolerable limits.
  • the light bulb according to the invention shown in FIG. 1 is a halogen incandescent lamp for a vehicle headlight, in particular an H7 lamp.
  • This lamp has a glassy, substantially cylindrical lamp vessel 1, which is provided at one end with a metallic base 2.
  • an axially aligned incandescent filament 3 is arranged, which are wrapped with a molybdenum tube 301, 302 spiral outlets 31, 32 are each welded to a power supply wire 4, 5.
  • the two power supply wires 4, 5 are each electrically connected to an electrical connection 6, 7 of the base 2.
  • the power supply wire 5 connected to the remote filament outlet 32 is provided with a strut 8 which is welded at three points to the power supply wire 5.
  • Both the strut 8 and the power supply wire 5 are formed as molybdenum wire with a thickness of 0.7 mm.
  • the strut 8 bridges a plurality of angled portions 51, 52, 53 of the power supply wire 5 and thereby causes a stiffening of the power supply wire 5.
  • the strut 8 has two right-angled ends, which are welded to the portion 51 and 53 of the power supply wire 5.
  • the strut 8 is also welded to the transition region between the sections 51 and 52 of the power supply wire 5.
  • the power supply wire 4 connected to the socket-like helical outlet 31 can also be provided with a strut which bridges the angled sections of the power supply wire 4.
  • the strut 8 and the power supply wires 4, 5 may also have a thickness less than 0.7 mm, for example, a thickness of only 0.645 millimeters possess.
  • the strut 8 may also have a different thickness than the power supply wire 5. For the thickness or the diameter of the strut 8 values in the range of 0.1 millimeters to 1.0 millimeters come into consideration.
