Definitions

  • the present invention relates to a glow starter after Preamble of claim 1 and a glow starter after Preamble of claim 2. It also relates to a discharge lamp according to the preamble of claim 9 and a lamp according to the preamble of claim 13.
  • high-pressure mercury vapor lamps are used in street lighting at designated fireplaces operated.
  • High-pressure mercury lamps usually ignite at mains voltage, the associated ballasts, in particular the chokes arranged in the ballast accordingly are designed. Details can be found in the regulation of the International Electrotechnical Commission (IEC) No.IEC 922, the concerns the construction of ballasts for discharge lamps, as well IEC 188, which specifies the electrical operating data and dimensions affected by mercury vapor lamps.
  • IEC International Electrotechnical Commission
  • Sodium vapor lamps are regarding their energy consumption more advantageous than mercury vapor lamps: this is how sodium vapor lamps correlate with a power consumption of 40, 65 and 110 W. in terms of luminous flux with mercury lamps, one Power consumption of 50 W, 80 W or 125 W. The energy saving is more than 15 percent. Conversely delivers a xenon containing sodium vapor lamp at 110 W power consumption about a luminous flux of 9500 lm in comparison to 6300 lm of a mercury vapor lamp of the same power or at 65 W power consumption 5000 lm compared to 3000 lm.
  • Discharge vessels can be used for high pressure sodium lamps with neon argon filling by utilizing the Penning effect Ignite the mains voltage, but the discharge vessels must do so be very large. Filling with xenon without Argon enables a significantly smaller dimensioning of the Discharge vessels. However, this has the disadvantage that for ignition ignition systems integrated in the lamp are necessary.
  • Conventional Generate internal igniter systems used in sodium vapor lamps a surge voltage, which is typically even 1.8 kV. Such high surge voltages would reduce the chokes in the ballasts of high-pressure mercury vapor lamps destroy permanently.
  • ballast resistor Without a ballast resistor, even when using an outside (capacitive) ignition aid attached to the discharge vessel defective discharge vessel or a defective welded joint full high voltage is present within the lamp, accordingly 1.7 kV to 2.5 kV, both on the discharge vessel and also on the inductance (choke). This can lead to a breakthrough of turns of inductance and thus a fire at the fireplace.
  • EP 0 450 523 and EP 0 565 113 disclose the use of a Internal ignition system with a ferroelectric ceramic known. Due to its internal structure, the ferroelectric works Ceramic as a capacitor and the fact that the dielectric at a certain voltage its electricity constant suddenly increased, as a switch. Switching off the charging current in this type of capacitor is used to induce the ignition voltage. Due to a possibly defective discharge vessel because of the design principle of ferroelectric Ceramic is the critical voltage range for inductance not exceeded. The ferroelectric ceramic, however, is very expensive.
  • the object of the present invention is a To further develop glow igniters of the type mentioned at the beginning, that it can be used without a ferroelectric ceramic Ignition of sodium vapor lamps on existing lights for High-pressure mercury vapor lamps (burning points) enables, even if the discharge vessel is defective, only voltages to the Inductance of the ballast get that no damage of inductance.
  • the filling gas of the glow starter proves to be particularly advantageous: essentially pure neon, or a mixture that contains about 10% by volume of neon and 90% by volume of argon, as well as a mixture, the about 10 vol .-% neon, 90 vol .-% argon and a radioactive Activating substance to provide a Basic level of free charge carriers included.
  • the filling pressure has proven to be advantageous compared to known glow igniters (for example WO 98/09317) to increase by at least about 30%. It is advantageous for prevention of sticking of the two electrodes in this increased Filling pressure the contact distance of the two electrodes in a range of 0.5 mm to 0.7 mm is selected.
  • the solution according to the invention also includes a lamp and a Discharge lamp with an outer bulb, in which a discharge vessel parallel to the series connection of an external temperature sensitive Switch and a glow starter according to the invention arranged is.
  • a discharge vessel parallel to the series connection of an external temperature sensitive Switch and a glow starter according to the invention arranged is.
  • the ignition voltage of the discharge vessel lower still further to about 600 V.
  • Fig. 1 shows a schematic representation of a circuit arrangement with a sodium vapor lamp connected to a ballast an inductor 12 provided by a choke is.
  • the inductor 12 is part of an already existing one Luminaire originally for the operation of high pressure mercury vapor lamps designed.
  • the lamp in an outer bulb 10 includes a discharge vessel 14, a glow starter 16 and an external temperature sensitive Switch 18.
  • the discharge vessel 14 is with xenon filled as base gas. Xenon only serves as a starting gas.
  • the Cold filling pressure of the xenon can range from 10 to 100 mbar, preferably 30 mbar.
  • the evaporation of Amalgam releases sodium and mercury in the discharge vessel, where mercury acts as a buffer gas and the discharge from sodium will be carried.
  • the glow starter 16 has a housing 17 which is filled with neon, or neon and argon, or preferably neon, argon and an activation substance.
  • a filling with 10% by volume neon and 90% by volume argon is preferred, with a cold filling pressure of 40 mbar.
  • the additional activation substance that may be used is preferably radioactive, with 0.25 mCi Kr 85 being preferred in this case.
  • a first and a second electrode 20, 22 form an inner, in the glow starter 16 arranged bimetal switch 15. Der The distance of the electrode 20 from the electrode 22 is in the cold Condition 0.5 to 0.7 mm.
  • the discharge vessel 14 is schematic an ignition aid 24, in particular a Mo wire or a sintered one Ignition aid, arranged with which the ignition voltage of the discharge vessel 14 can be significantly reduced. Practical Tests have shown that the ignition voltage of 1.2 kV can be reduced to about 600 V.
  • the outer temperature sensitive Switch 18 comprises two electrodes 26, 28. The series connection glow igniter 16 and external temperature-sensitive switch 18 lies parallel to the discharge vessel 14.
  • Fig. 2 shows in representation a) the position of the switch 15 in the glow starter 16 and the position of the switch 18 each in the cold state.
  • the outer switch 18 is closed, the inner switch 15 is open.
  • a glow discharge ignites between the electrodes 20, 22 of the inner switch 15 when a voltage, for example mains voltage, is applied, in which a current of the order of 30 to 40 mA flows, which leads to heating.
  • the first electrode 20 moves towards the second electrode 22, see FIG. 2b, until they touch.
  • FIG. 2c the short circuit between the electrodes 20 and 22, there is no further heat input into the bimetal. This leads to cf. Fig. 2c that the inner switch 15 opens again.
  • FIG. 2d shows the position of the switches 15, 18 with moderate heating shortly after the lamp is switched on, corresponding to a first temperature .
  • 2e shows the position of the switches 15, 18 with pronounced heating, clearly after the lamp has been switched on, corresponding to a second temperature, the second temperature being higher than the first temperature.
  • the outer switch 18 opens even with moderate heating, so that both switches 15, 18 are open. With further heating, the inner switch 15 closes again (FIG. 2e). However, this does not lead to a short-circuiting of the discharge vessel 14, since the outer switch 18, which is still open, prevents a current flow through the series circuit comprising glow starter 16 and outer switch 18.
