Definitions

  • the present invention relates generally to the production of ions in air, and more particularly to the production of unipolar ions. Still more specifically, the present invention relates to a device for the production of unipolar ions for electrical environment control in enclosed spaces.
  • a further object of the invention is to provide such an arrangement which is simple and inexpensive to construct.
  • An additional object is to provide an arrangement of the type here in question which eliminates or at least reduces to an absolute minimum, the undesirable side effects mentioned above.
  • I provide, in a device for producing unipolar ions in air, an electrically excitable source of visible and ultraviolet electromagnetic radiation.
  • This source is at least in part bounded by a wall consisting of vitreous material, permeable to the emitted radiation.
  • An electrically energizable electrode means is associated with the source and includes a plurality of resilient filament portions having free ends exteriorly engaging the wall.
  • the source of electromagnetic radiation is advantageously a conventional gas discharge tube the inside of whose glass wall may or may not be coated with a lightemitting substance, such as the fluorescent or phosphorescent metallic salts which are well known in the art.
  • a device constructed in accordance to the present invention produces significant amounts of unipolar air ions without, however, producing ozone or nitrous oxides. Furthermore, it does not produce objectionable radiation in the area within which the ions are produced. It is well known, of course, that a normally operated conventional gas discharge tube will produce a certain amount of ultraviolet radiation. However, this radiation is confined to the immediate vicinity of the tube and is not normally sufficient to produce ions. Rather, it simply effects increased excitation of the molecules. It, now, the electrode according to the present invention is energized, then a strongly non-homogenous electric field is established at the ends or tips of the electrically conductive filaments of the electrode which engage the glass wall of the tube only with respective very small surface areas.
  • the maximum strength of this field can be determined very precisely by selecting the desired rectification. Relatively small field strengths are sufficient for effecting the desired ionization in conjunction with the molecular excitation produced by the presence of the ultraviolet radiation emitted by the gas discharge tube.
  • the so-called quiet discharge phenomena which occur in this case can be maintained at such low levels that it is possible to suppress the production of ozone and nitrous oxides as well as of radiation frequencies which produce radio-Wave interference and which normally occur during corona discharge at high field strength, can be suppressed completely, or to a minimum, at which they become insignificant and are no longer of concern.
  • the inside of the glass wall of the gas discharge tube is coated with a light-emitting substance, such as fluorescent or phosphorescent metallic salts, in the well known manner.
  • a light-emitting substance such as fluorescent or phosphorescent metallic salts
  • Such coating partially absorbs the ultraviolet radiation produced by the tube and thus further serves to limit the influence of this ultraviolet radiation to the immediate vicinity of the tube exterior.
  • FIG. 1 is a side-elevation of an arrangement embodying my invention
  • FIG. 2 is a cross-section through the embodiment of FIG. 1;
  • FIG. 3 illustrates a circuit for use with the embodiment illustrated in FIGS. 1 and 2.
  • the electrically conductive electrode is provided in form of a rod-shaped element 1.
  • the electrode 1 is provided with a plurality of filamentary wire tips 2 consisting of a suitable material, such as steel wire, and it will be understood that these wire tips 2 must be hair-fine.
  • Spring clamps 3, each comprising two arms 4 and a connecting bight 5, serve to clampingly and releasably connect the electrode element 1 to a conventional gas discharge tube 6.
  • this gas discharge tube 6 is assumed to consist of a cylindrical glass wall or body 7 whose inner side is coated with a light-emitting layer 8 of suitable material. This construction, and the material for the layer 8, are of course well known and will not be further described.
  • Each end of the gas discharge tube 6 is provided with an electrode 9 having two terminals 10, 10 or 11, 11.
  • the clamps 3 are so constructed and configurated, as is the electrode 1 that the clamps 3 will so bias the electrode 1 towards the body of the gas discharge tube 6 that the resilient wire tips 2 are lightly biased into engagement with the outer surface of the cylindrical glass body 7.
  • the circuit arrangement illustrated in FIG. 3 shows an electrode 1 is connected with a source 13 of direct current via a high ohmic resistor 12.
  • the source 13 advantageously will have a potential of approximately 2,000 volts. While one pole of the source 13 is connected in this manner with the electrode 1, the other pole of the source 13 is connected to ground potential.
  • a high-ohmic resistor having a resistive value on the order of 10 ohms may be interposed in circuit between the electrode 1 and the associated pole of source 13.
  • the gas discharge tube 6 is connected with its terminals 10 via conductors 14, and with its terminals 11 via conductors 15 to a conventional ballast arrangement 16 which is energized from a source 17 of alternating current.
  • This source may of course be the conventional net current of or 220 volts.
  • Reference numeral 18 indicates that the ballast 16 is also grounded.
  • a glow discharge takes place in the gas discharge tube 6 so that ultraviolet radiation is emitted.
  • This ultraviolet radiation excites the light-emitting coating 8 and in the course of so doing is partly absorbed.
  • Some of the ultraviolet radiation penetrates to the immediate exterior of the body 7, that is to the outer surface thereof, where the tips of the filaments 2 are in engagement with the body 7.
  • the vibrations which take place within the interior of the gas discharge tube effect similar vibrations in the ends of the very fine hairlike wire filaments 2 with the result that microscopically small corona discharges occur.
  • the device according to the present invention may, if desired, be combined with an arrangement for producing an electrostatic field in an enclosed space.
  • the electrode 1 may itself be constructed as a ceiling electrode to be mounted on the ceiling of a room or as a part of such a sealing electrode. This concept of producing an electrostatic field in an enclosed space is already known and is being mentioned here only for the sake of completeness, having no direct connection with the present invention.
  • a combination comprising an electrically excitable gas discharge tube constituting a source of visible and ultraviolet electromagnetic radiation and being at least in part bounded by a wall consisting of vitreous material which is permeable to the emitted radiation; a source of alternating current for exciting said tube whereby the same undergoes slight vibrations; electrically energizable electrode means, including resiliently deflectable filament means exteriorly contacting said wall; and a source of direct current having a pole conductively connected with said electrode means whereby, in response to energization of said tube and vibration of the same, momentary displacements of said filament means out of contact with said wall caused by the vibrations of said tube will result in minute corona discharges between said filament means and said wall while the former is out of contact with the latter.
  • said wall being a tubular casing of said gas-discharge tube and having an inner side coated with a substance adapted to emit light and to partially absorb ultraviolet radiation upon excitation of said tube.
  • said electrode means comprises a rod-shaped portion extending along said tube exteriorly thereof, said filament means being provided on said rod-shaped portion and engaging said wall.
  • said springclip means comprises a plurality of spring-clip members each having two arms arranged to embrace said tube, and a connecting portion extending between said arms and adapted to engage said rod-shaped portion of said electrode means for holding the same in predetermined position relative to said tube.
  • ballast means operatively associated with said tube and being connected with another pole of said source of direct current.
  • said filament means comprises a plurality of discrete filaments.
