Definitions

  • the invention relates to a gas discharge lamp with one of an outer bulb enclosed discharge vessel and a jump-start antenna guided around the discharge vessel.
  • the invention relates to HID (high-intensity discharge) lamps such as.
  • High-pressure sodium lamps and in particular MPXL (micro power xenon light) lamps such as be used in motor vehicles.
  • MPXL micro power xenon light lamps
  • the problem with the known antennas is that they are not readily MPXL lamps can be used because their dimensions are significant are smaller than the conventional HID lamps, on the other hand these lamps extremely hot (around 600 ° C on the burner, around 400 ° C on the outer bulb), so simple Antennas deform or even melt under the influence of heat.
  • the antennas are in direct contact with or at least are arranged directly on the burner, during operation that in Burners in ionized form contain sodium reinforced in or even through the wall of the discharge vessel diffuses, which greatly affects the durability of the lamps.
  • the invention is based on the object of a gas discharge lamp type mentioned above, in particular an MPXL lamp, in which the positive effects of a jump-start antenna even with small and smallest discharge vessels can be used without a great deal of design effort, without being reinforced To induce sodium diffusion.
  • the problem is solved on the one hand by a gas discharge lamp with one by one Outer bulb enclosed discharge vessel and one around the discharge vessel Jump start antenna, the jump start antenna on the inside or outside wall of the Outer bulb is provided.
  • the jump start antenna also integrated in the outer bulb, e.g. melted when blowing or pouring the piston.
  • the invention is based on the surprising finding that even with one The ignition voltage, which is arranged directly on the discharge vessel, considerably increases the ignition voltage can be reduced, with the typical MPXL ignition voltage of more than 10 kV both with pulsed ignition and with resonance ignition reduced by up to 40% could be.
  • the invention has the great advantage that the known antennas partially necessary complex support and support structure can be dispensed with, because the outer bulb serves as a carrier.
  • MPXL lamps equipped according to the invention especially in high-frequency operation, they tend to misfire much less often, which is due to the fact that the antenna has parasitic discharge phenomena prevented and the equipotential lines typical for HF operation closer to Discharge vessel binds.
  • the starting aid antenna can advantageously be optimal in a particular application adapted manner, e.g. using a wire made of electrically good conductive material that is wrapped one or more times around the outer bulb, or by means of a metallic arranged on the outside or inside of the outer bulb Ring.
  • the antennas provided on the outside of the piston are special easy to implement and can be used in particular when finished or at least finished constructed MPXL lamps can be easily retrofitted, which is a great advantage because the construction of an MPXL lamp is very complex and the subsequent installation the previously known antennas represented a considerable effort. Also show some lamps only in the practical test with certain igniters in the cold and / or Hot ignition phase a certain unwillingness to ignite.
  • the ignition voltage by a on the outer bulb attached simple jump starter antenna can be reduced.
  • the starting aid antenna can be used in an expedient development of the invention as a so-called plasma antenna with a gas-filled annular tube be an electrode in the tube, which is both a capacitive and can also be a direct electrode.
  • a glow discharge in the tube has the same effect as a ring, a coil or a layer of conductive material.
  • Fig. 1 is a MPXL lamp designated in its entirety with a Version 12, an outer bulb 14 and a discharge vessel 16 are shown schematically. Two electrodes 18 and 20 are arranged in the discharge vessel, the electrode 20 forms the so-called return pole and via a return wire 22 with not shown Components in the version 12 or in particular a starter is connected.
  • the return wire 22 is an annular, the outer bulb and here for Clarification exaggerated high jump antenna 24 connected to the Ignition voltage by equalizing the field structure in the area of the electrode 18 reduced without contacting the discharge vessel 16 or a measurably higher one To cause sodium diffusion into the walls of the discharge vessel 16.
  • FIG. 2 shows an MPXL lamp essentially corresponding to the lamp of FIG. 1 shown, the parts corresponding to the parts of Fig. 1 with deleted reference numerals were provided so that a new description can be dispensed with.
  • the main difference to the lamp according to FIG. 1 lies in the jump-start antenna 24 ', which in this exemplary embodiment consists of a multiple around the outer bulb 14 ' wound wire, also connected to the return wire 22 '.
