Definitions

  • the invention relates to a discharge lamp arrangement with a lamp bulb, in which a Noble gas is enclosed, with two internal electrodes arranged in the lamp bulb and with an auxiliary ignition electrode, which extends outside the lamp bulb and extends longitudinally thereon is closely located on its surface.
  • the object of the invention to form a discharge lamp arrangement with such an auxiliary ignition electrode, which on the one hand is inexpensive to manufacture and on the other hand reliably high Guaranteed service life of the discharge lamp.
  • this object is achieved in that elevations are arranged on the lamp bulb are at which the auxiliary ignition electrode is applied.
  • these surveys made of the same material as the lamp bulb.
  • the auxiliary electrode can be fixed by the elevations, so that it does not move over the circumference of the lamp bulb. Elaborate precautions that are tight the ignition auxiliary electrode on the lamp bulb should also be eliminated Use as a strobe lamp.
  • the elevations are preferably each formed in pairs and on both sides of the Auxiliary electrode arranged.
  • a mesh knot be fixed by two elevations each enclose the stitch between them.
  • the surveys can alternate on both Be arranged sides of the auxiliary ignition electrode.
  • At least one elevation is provided that extends from the surface extends away from the lamp bulb and at its end facing away from the lamp bulb has a thickening in relation to the projection on the lamp bulb, the Auxiliary electrode is at least simply wrapped around the survey approach.
  • Elevation is in the shape of a mushroom.
  • the arrangement has the advantage that the auxiliary ignition electrode does not have to be attached around the circumference of the lamp bulb; it is sufficient a straight-line design along the lamp bulb, since it fits securely against the lamp bulb is guaranteed by the mushroom shape of the elevation.
  • the lamp bulb is in a lamp housing arranged, the auxiliary ignition electrode being held on the lamp housing.
  • the lamp housing also called luminaire body
  • the lamp housing has a permanently installed auxiliary ignition electrode. This is installed once and is retained even when the lamp is changed. The This means that the discharge lamp itself can be made much simpler and therefore less expensive be and the fixation of the auxiliary ignition electrode on the lamp housing ensures a firm Position relative to the lamp bulb, so that the above-mentioned deposits appear remain limited in a small area. In addition, with such an arrangement ensures safer contacting of the ignition auxiliary electrode.
  • the auxiliary ignition electrode can expediently be designed as a resilient metal bracket, which can be applied to the lamp bulb by the spring force. During the operation of the Discharge lamp arrangement vibrations of the lamp bulb are caused by the Compensates for spring properties.
  • the lamp housing is one along of the lamp bulb extending reflector which has a metallic zone which is designed as an auxiliary ignition electrode.
  • the reflector can also be made of a metal sheet be formed or have a metallic coating facing the lamp bulb.
  • the reflector preferably has along the lamp bulb as an auxiliary ignition electrode serving formation, which is designed pointing in the direction of the lamp bulb.
  • Such a shape can be designed as a web, bead or bead. Such orders are very easy to manufacture and very safe to operate.
  • such Arrangement has the advantage that the discharge lamp itself by the operating personnel in an almost can be mounted in any way, without the need for a specific position of the auxiliary ignition electrode needs to be respected.
  • the distance between the auxiliary ignition electrode and the lamp bulb is expedient in such Arrangements about 0.1 to 0.2 mm in size for fixed reflectors, which also as Auxiliary electrode serve to prevent abrasion due to vibration of the lamp bulb the reflector arises.
  • auxiliary ignition electrodes For example, from the prior art described are mesh-like around the lamp bulb known auxiliary ignition electrodes. These can easily be found in the Figures 1 and 2 drawn arrangements are fixed.
  • the one around the lamp bulb 1 winding auxiliary ignition electrode 2 is fixed to its mesh node 3 by elevations 4.
  • This Elevations 4 are made of the same material as the lamp bulb 1, that is, of glass.
  • the Fastening clamps 5 of the auxiliary ignition electrode 2 also serve as contacts, whereby only a mounting bracket 5 is contacted.
  • the corresponding contact is in the lamp housing arranged and is connected to the lamp housing when the lamp electrodes 6 are connected pressed against the corresponding fastening clamp 5 by spring force.
  • the lamp electrodes 6 are guided through the wall of the lamp bulb 1 and form the internal electrodes there 10th
  • Fig. 2 shows a similar training. However, the surveys 3 are alternating in the Drawing arranged above or below the auxiliary ignition electrode 2, so that the auxiliary ignition electrode 2 do not move around the lamp bulb 1 in this example either can.
  • Fig. 3 shows a slightly different training.
  • the auxiliary ignition electrode 2 is wound around the latter. At their ends is they locked with mounting clamps 5 in a known manner. This auxiliary ignition electrode 2 can not or only slightly change in their relative position to the lamp bulb 1.
  • the discharge lamp is attached to the lamp housing 7 with its lamp electrodes 6.
  • the lamp housing 7 also carries the auxiliary ignition electrode 2, which is firmly contacted with the lamp housing 7 and thus remains in the lamp arrangement even when the discharge lamp itself is replaced and is not exchanged.
  • the discharge lamp can thus be much simpler and cheaper be constructed.
  • 5 shows a further possibility of the arrangement.
  • the discharge lamp with its lamp electrodes 6 is also on the lamp housing 7 attached.
  • the bottom of the lamp housing 7 is designed as a reflector 8.
  • the reflector 8 can either be designed as a metal sheet or on its side facing the lamp bulb 1 Side be provided with a metal layer. It is via a contact 9 with the circuit arrangement connected.
  • the circuit arrangement is designed in a customary and known manner and explained for example in the prior art already described.
  • FIG. 6 A specific design of the auxiliary ignition electrode 2 as part of the reflector 8 is shown in FIG. 6 shown.
  • the auxiliary ignition electrode 2 is designed as a bead (FIG. 6a), as a bead (FIG. 6b) or as a web (FIG. 6c) and arranged directly on the reflector 8.
  • the auxiliary ignition electrode also runs here 2 along the lamp bulb 1, extending between the two inner electrodes 10.
  • the distance between the auxiliary ignition electrode 2 and the lamp bulb 1 is approximately 0.1 to 0.2 mm, in the event of vibrations of the lamp bulb 1 during operation, abrasion points on the reflector 8 to prevent.
  • a continuation of the auxiliary ignition electrode 2 at the same distance also beyond the electrodes 10 does not make sense, since in such cases voltage breakdowns between the inner electrodes 10 and the auxiliary ignition electrode 2 are to be expected.
