  • Ignition voltage is used in many applications based on the Build principle of throttle starter circuit, uses a glow starter, which traditionally uses a glow starter and an interference suppression capacitor contains.
  • This glow starter is parallel to the lamp and in series connected to the lamp electrodes.
  • These known glow starters have two electrodes, at least one of which is made of thermobimetal. The electrodes are in a glow igniter bulb filled with a filling gas arranged.
  • a voltage - usually the Mains voltage - to the electrodes and the associated glow discharge the bimetal heats up between the electrodes, so that the contact defined by the two electrodes is closed and the full short circuit current of the choke through the electrodes of the lamp flows.
  • the prerequisite for starting the lamp is that within the Glow igniter pistons have a certain minimum number of free electrons must be present for an ionization process and for heating the glow discharge required for the electrodes. At a too few free electrons can result in a practical Use of unacceptable delay in the ignition of the ignition process (Ignition delay), and in the worst case for not igniting the glow starter, come.
  • Ignition delay unacceptable delay in the ignition of the ignition process
  • glow igniters show little or no evidence Ignition delay when starting the low-pressure discharge lamp at brightness (Daylight or artificial light). The reason for this is in that by the light falling on the electrodes of the glow starter free electrons via photo effect and / or photo ionization of excited Atoms of the fill gas are generated.
  • the ignition delay is special when the lamp is ignited in the dark pronounced because the gain in the electric field between the electrodes is so small that the few charge carriers generated - in particular Electrons - due to loss processes, such as recombination, inelastic impacts with impurities are lost and the The electron avalanche thus extinguishes before it arrives at the anode.
  • the object of the invention is a method to operate a low-pressure discharge lamp, a glow starter, a compact fluorescent lamp equipped with such a glow starter, one equipped with such a compact fluorescent lamp Luminaire, a glow starter and one operated with a glow starter To create luminaire, the ignition delay with minimal device technology Effort is minimized.

Because of this Storage phosphor in a simple way without additional wiring suitable position can be attached, is the effort to manufacture much less than with the solution described at the beginning.
  • the storage phosphor can, for example, be applied to the glow starter bulb be, both directly in the form of a coating as well indirectly by applying another preliminary product, which as Carrier for the storage phosphor serves or contains it (e.g. application a transparent plastic film that contains the storage phosphor).
  • the storage phosphor can also be used for glow starters be attached to any kind of glow starter components
  • the glow starter surrounds the housing (e.g. as an admixture to the plastic granulate).
  • KLL glow starters also have the option of using the phosphor in any way on the lamp parts surrounding the glow starter or to attach the condenser (e.g. as an admixture to the plastic of the Lamp base).
  • a particularly simple solution for glow starters is the starter sleeve Manufacture by injection molding from plastic and thereby the Mix the storage phosphor as a powder into the granulate so that it is in the starter sleeve is integrated.
  • This variant requires the use of transparent base material for the manufacture of the starter sleeve in advance.
  • Glow igniter to be provided with a transparent plastic film that the Contains storage phosphor as an admixture.
  • free load carriers presupposes that in the area of Electrodes of the glow starter at least one material is present which Irradiation with the light of the storage phosphor photoelectrons in sufficient Dispenses quantity to start the photo ionization.
  • the coating is preferably applied in the area of strong potential gradients, thus formed in the area of the smallest electrode distances.
  • the storage phosphor is preferably selected such that it emits light in Wavelength range between the transmission limit of that for the glow starter piston used glass and the relevant cut-off wavelength for photo emission at the electrodes. This cutoff wavelength depends on the chemical composition of the electrode materials used as well as the type of their contribution and their association.

At least one 9 of the electrodes 9, 10 consists of thermobimetal, so that the two electrodes 9, 10 by the thermal deflection of the bimetal can be brought together in plant.
  • the starter sleeve 4 is in the Injection molding process made from a transparent plastic, whereby a proportion of storage phosphor 5 is supplied to the plastic granulate.
  • storage phosphor 5 is capable of in daylight or during operation the low-pressure discharge lamp assigned to the glow starter Save light and then emit it over a longer period of time. This process is roughly comparable to the electrical charging process a battery that then transfers its energy to an electrical one Consumer.
  • the storage phosphor 5 thus acts like an "auxiliary lighting", via which light is emitted to the glow starter 2 becomes.
  • the storage phosphor 5 in the sleeve Injection molding can also be used, for example, as a coating on the interior or Outer peripheral surface of the starter sleeve 4 or on the inner or outer surface of the glow starter piston 6 are applied.

In addition, this radiation must come from all materials in between (For example, glass of the glow igniter bulb 6) at least partially let through become.
  • a suitable storage phosphor 5 has an emission band has in the wavelength range from about 390 to 530 nm, while the Cutoff wavelengths of the elements cerium and cerium mixed metal Praseodymium are at 430 nm and at 460 nm (proportions of these elements in the Cerium mixed metal: 48-55% by weight or 4-7% by weight).
  • the light emission of the storage phosphor 5 causes the electrode 10 provided with the metal plate 15 free electrons are generated by photo-effect, which are created when a Initiate a voltage on the glow starter and thus a Townsend avalanche enable the glow starter 1 to be ignited without significant ignition delay.
