Definitions

  • the invention relates to a lighting system consisting of an electronic operating device and at least one gas discharge lamp with filaments.
  • a lighting system consisting of an electronic operating device and at least one gas discharge lamp with filaments.
  • the preheating process of the gas discharge lamps is to be improved.
  • An alternating voltage generator feeds in an electronic operating device for gas discharge lamps G, which works at a frequency that is significantly higher than the grid frequency, energy in a load circuit.
  • the AC voltage generator G is connected to one Load circuit, consisting of a lamp choke L1, a resonance capacitor C1 and a gas discharge lamp Lp.
  • the following is the gas discharge lamp called lamp for short.
  • the lamp choke usually forms L1 and the resonance capacitor C1 a series resonant circuit, the the AC voltage generator G is connected.
  • the lamp Lp is parallel to the Resonance capacitor C1 switched. This configuration is not just for operation the lamp Lp suitable, but also allows the lamp to ignite.
  • the load circuit Before the When the lamp is ignited, the load circuit is a high-quality series resonant circuit. If this resonant circuit is excited with its resonance frequency, then it is created above the Lamp Lp a high voltage, which leads to the ignition of the lamp. To increase the Before the ignition, the life of the lamp must be the filaments W1 and W2 Lamp Lp can be preheated. In order to implement the preheating, the one shown in FIG 1 circuit shown proven. The resonance capacitor C1 is not directly connected the lamp inductor L1 and the alternating voltage generator G. Much more the connection to the lamp choke L1 is made via the filament W1 and the connection to the alternating voltage generator G via the helix W2.
  • the preheating current must be strong enough to turn the filaments to the required temperature in a time that should be in the range of one second heat.
  • the frequency of the voltage, that of the AC voltage generator G emits during preheating should not be selected too high.
  • the voltage at the lamp Lp must not increase during preheating be high, as otherwise glow discharges that damage the filament will occur.
  • the frequency of the voltage generated by the AC generator G during the Output preheating should not be chosen too low.
  • the decisive factor is that of Lamp manufacturer specified non-ignition voltage. It is allowed during preheating not be exceeded. For many lamps there is no frequency for the while the preheating voltage output by the alternating voltage generator G, for which both of the above Conditions are met. All possible frequencies are either too close to the resonance frequency of the series resonant circuit, consisting of lamp choke L1 and resonance capacitor C1, and thus result in too high a voltage on the lamp Lp, or they are too far from the resonance frequency and result thus a too low preheating current.
  • This task is by a lighting system with the features of the preamble of the claim 1 solved by the features of the characterizing part of claim 1.
  • the resonance capacitor C1 described above is replaced by an impedance network that has the following properties: the impedance function of the impedance network has a zero at frequency f1.
  • the impedance network is over the Filaments W1, W2 connected in series with lamp choke L1.
  • the series connection of the Impedance network with the lamp choke L1 has an impedance function with a zero at frequency f2.
  • the AC voltage generator is used for preheating G now a voltage whose essential spectral component at a frequency lies close to the frequency f1 for the zero point of the impedance function of the Impedance network.
  • Near frequency f1 describes in this context a frequency range from 0.8 * f1 to 1.2 * f1.
  • the AC generator G outputs a voltage for ignition whose essential spectral component is at a frequency that is close to the frequency f2 for the zero point of the impedance function of the series connection, consisting of the lamp choke L1 and the impedance network.
  • a preheating circuit according to the invention can also be used for lighting systems multiple lamps can be used. All combinations of parallel and Series connection possible. With the parallel connection, several lamp circuits, which an impedance network according to the invention, a lamp choke and a Lamp included, connected in parallel. With the series connection only the Lamps can be connected in series. Then it is sufficient that the invention Impedance network with a helix connection of the first and the last
