Definitions

  • the invention relates to a ballast for operating at least one low-pressure discharge lamp according to the preamble of patent claim 1.
  • ballast for operating two parallel-connected low-pressure discharge lamps is disclosed on a half-bridge inverter.
  • the ballast has a transformer with two similar windings, which are each connected in one of the two lamp current branches. This transformer works as a differential current transformer. If one of the two lamps ignites earlier than the other, the ignition of the other lamp is supported by means of the transformer.
  • the EP 0 422 594 A1 discloses a dimming device for a fluorescent lamp.
  • the DE 42 43 955 A1 discloses a ballast with an inverter for at least one parallel operated gas discharge lamp pair, which is associated with a balancing transformer with two oppositely acting in opposite directions windings.
  • ballasts for operating a plurality of low-pressure discharge lamps
  • the problem often arises that the lamps shine differently brightly in dimming operation. If the lamps are arranged in different, parallel-connected current branches, this problem can be caused by different currents in the current branches. On the other hand, this problem also occurs in lamps, which - as in a series connection of two lamps - are arranged in the same branch of current.
  • the ballast comprises an inverter provided with a downstream load circuit designed as a resonant circuit into which the lamps are connected, those lamps which are directly connected to the resonant circuit components often shine brighter than the downstream lamps.
  • This variant of the invention is particularly well suited for the operation of three parallel-connected low-pressure discharge lamps. It is characterized by a particularly simple wiring of the lamp.
  • the two transformers act as a differential current transformer due to the opposite arrangement of their first and second windings.
  • the special turn ratio of 2: 1 between the first and second windings in both transformers ensures that all three current branches are symmetrical, since the second windings of the two transformers are traversed by the partial currents of two current branches.
  • it is ensured by the special arrangement of the windings of both transformers that on the one hand, the currents in the three current branches are balanced and on the other hand, the losses due to parasitic Capacities are compensated in each individual branch or in each individual lamp. Therefore, all three lamps shine brightly even in strong dimming.
  • the ballast according to the invention is advantageously designed as an inverter with a downstream load circuit, wherein the electrical connections for the low-pressure discharge lamps or the power branches are arranged with the electrical connections for at least one low-pressure charge lamp in the load circuit to operate the lamps with a high-frequency alternating current can.
  • the operation of the lamps with a high frequency alternating current improved the light output and allows easy brightness control of the lamps by changing the AC frequency.
  • the downstream load circuit is designed as a series resonant circuit.
  • the design of the load circuit as a series resonant circuit enables easy ignition of the low-pressure discharge lamps by means of the resonance peaking method.
  • the ballast has a half-bridge inverter which consists essentially of the transistors T1, T2 and a (not shown) driving device for the transistors T1, T2 and the half-bridge capacitor C2.
  • the half-bridge inverter T1, T2 is supplied at its voltage inputs with a DC voltage U, which is generated in a known manner by filtering and rectification of the AC line voltage.
  • the filter and rectifier circuit of the ballast are therefore not shown in the figures and will not be described further here.
  • the inductance L1 is connected at the center tap M1 between the transistors T1, T2 of the half-bridge inverter.
  • the inductor L1 To the inductor L1 is the first terminal of the capacitor C1 is connected, while the second terminal of the capacitor C1 is connected to the ground potential.
  • the inductance L1 and the capacitor C1 form a series resonant circuit.
  • the first terminal of the resonance capacitor C1 is connected via a parallel connection of a plurality of low-pressure discharge lamps or a series connection of low-pressure discharge lamps or a combination of both with the first terminal of the half-bridge capacitor C2.
  • the second terminal of the half-bridge capacitor C2 is at ground potential.
  • Half of the supply voltage U of the half-bridge inverter is applied to the half-bridge capacitor C2.
  • the transistors T1, T2 are switched by means of the drive device in a known manner alternately with a frequency of more than 20 kHz, so that the center tap M1 is alternately connected to the ground potential and the positive potential U. Between the center tap M1 and the second terminal of the half-bridge capacitor C2 therefore flows a correspondingly high-frequency alternating current, with which the low-pressure discharge lamps are operated.
  • the ballast for operating low-pressure discharge lamps in particular of fluorescent lamps, which are each provided with two heatable electrode coils for generating a gas discharge. Each electrode coil has two electrical connections, via which the electrode coil can be acted upon by means of a (not shown) heater H in a known manner with a heating current to enable a gentle Lampenbetried.
  • the ballast is used to operate three parallel-connected low-pressure discharge lamps, in particular fluorescent lamps L10, L11, L12
  • FIG. 1 the circuit arrangement of this ballast is shown schematically.
  • this ballast has two transformers Tr10, Tr11, each with two windings 10a, 10b, 11a, 11b.
  • the turns ratio of the windings 10a, 10b of the first transformer Tr10 is 2: 1.
  • the turns ratio of the windings 11a, 11b of the second transformer Tr11 is 2: 1.
  • the winding 10a of the transformer Tr10 is connected in the first current path, in series with the fluorescent lamp L10.
  • the second winding 10b of the transformer Tr10 is connected both in the second current path, in series with the fluorescent lamp L11, as well as in the third current path, in series with the fluorescent lamp L12.
  • the winding 10a is therefore traversed by the discharge current of the fluorescent lamp L10, while the winding 10b is traversed by the discharge currents of the fluorescent lamps L11 and L12.
  • the two windings 10a, 10b are wound in opposite directions, so that they are traversed in opposite directions by the discharge current of the lamps.
  • the first winding 11a of the transformer Tr11 is connected in the third current path, in series with the fluorescent lamp L12, while the second winding 11b is connected both in the first current path, in series with the fluorescent lamp L10, and in the second current path, in series with the fluorescent lamp L11, is switched.
  • the winding 11a is therefore traversed by the discharge current of the fluorescent lamp L12, while the winding 11b is traversed by the discharge currents of the fluorescent lamps L10 and L11.
  • the windings 11a, 11b are arranged in opposite directions, so that they are traversed in opposite directions by the discharge currents or lamp currents.
  • the first transformer Tr10 is the fluorescent lamps L10 to L12 immediately upstream
  • the second transformer Tr11 is the fluorescent lamps L10 to L12 immediately downstream. All three current paths are thus formed completely symmetrical.
  • the two transformers Tr10, Tr11 each act as differential current transformers and ensure that regardless of the dimming level, all three lamps light up the same brightly.
