Definitions

  • the invention relates to a circuit arrangement with a transformer for operating glow fluorescent lamps on a mains voltage in accordance with the preamble of claim 1.
  • a circuit arrangement is e.g. known from US-A-3 360 753.
  • Glow fluorescent lamps need a power source that everyone can start with Ignition phase provides a high ignition voltage that immediately after ignition the glow fluorescent lamp collapses to the burning voltage and from then on the desired combustion current should be as linear as possible at this voltage delivers until the current phase is over.
  • the currentless period until the next ignition should be as short as possible because the ignition voltage for the next burning phase the higher the rapidly decaying must be Rebuild ionization. So this fact made up to now the operation of glow fluorescent lamps with conventional 50 Hz transformers impossible.
  • the object of the invention is therefore to provide a circuit arrangement with a Transformer for operating glow fluorescent lamps on a mains voltage to create that has a high efficiency and inexpensive is to be produced.
  • the glow fluorescent lamps are supposed to be safe to be ignited and flicker-free to operate.
  • the magnetic reflux magnetizes then the second leg in the opposite direction and thus causes the ignition voltage to be reached in the next phase an earlier time.
  • the shorter time interval until the rise of the secondary voltage in the following phase also causes the Ionization in the ignition path of the lamp has subsided less, and thus a lower ignition voltage is required for re-ignition.
  • FIG 1 is a circuit arrangement according to the invention for operating a Glow fluorescent lamp GLL type T4 with a power consumption of 5 W on a mains AC voltage of 230 V.
  • the transformer TR has three windings, a primary winding Wa, a first Winding part Wb1 of the secondary winding and a second winding part Wb2 of the secondary winding.
  • the primary winding Wa and the first Part of the secondary winding Wb1 are on a first leg I of the magnetic core (see Figure 2) attached and electrically connected.
  • the second winding part Wb2 of the secondary winding is on the second Leg II of the magnetic core attached. It is also in the primary circuit a PTC thermistor connected, which serves as a fuse element.
  • Figure 2 shows the structure of the E and I core sheets on a scale of 2: 1 for one Transformer TR, as in the circuit arrangement shown in Figure 1 is used.
  • the core sheets consist of iron sheets of type St 12 and have a thickness of 0.63 mm. For the magnetic core of the above 16 such sheets are required for the transformer.
  • the windings consist of a lacquered copper wire and have the following dimensions: Primary winding Wa Secondary winding Wb1 Secondary winding Wb2 Number of turns 7,600 8 630 22 880 Wire thickness 0.05 mm 0.04 mm 0.04 mm
