Definitions

  • the invention relates to an auxiliary device for regulating the brightness of low-voltage fluorescent lamps with ballast by means of phase gating-controlling dimmers, in particular according to the preamble of claim 1.
  • phase control dimmers often also called voltage control dimmers, which regulate the brightness of lamps by varying the voltage.
  • voltage control dimmers In the case of low-voltage fluorescent lamps, there is only a regulation range of just under 10%, since low-voltage fluorescent lamps go out at a voltage below 200 volts. There are therefore special dimmers on the market that are technically and economically complex.
  • auxiliary device for dimming fluorescent lamps (GB-A-2 079 551) it is ensured that the heating of the fluorescent lamp is switched on during the dimming process. In this case, extensive circuitry expenditure is required between the dimmer and the electronic valve and to the fluorescent lamp. Nevertheless, as is well known, such measures make the regulatory area relatively narrow.
  • the object of the invention is to develop an improved auxiliary device for regulating the brightness of low-voltage fluorescent lamps by means of commercially available phase gating-controlling dimmers.
  • the described object is achieved by an auxiliary device according to claim 1.
  • the dimmer is not inductively loaded by the series reactor and the high-voltage coil ensures basic ionization in the lowest lighting stage.
  • the high-voltage coil can be particularly easily integrated into the auxiliary device in a quick-start device known per se.
  • the high-voltage coil can in particular be designed for a voltage on the output side of approximately 600 to 1500 volts.
  • the two secondary windings of the inductively operating quick start device ensure that the lamp electrodes are heated in the usual way.
  • An auxiliary device with a high-voltage coil makes it possible to regulate the brightness of low-voltage fluorescent lamps particularly far.
  • the auxiliary device can also be retrofitted between the lamp-side connections and the mains-side connections for the ballast choke and for the dimmer and for the center conductor connection.
  • the electronic valve can be a triac with a capacitor connected upstream on the control side.
  • the low-voltage fluorescent lamp 1 is limited in the usual way in its current consumption by the ballast 2.
  • the brightness of the lamp can be regulated by means of a commercially available phase control dimmer 3.
  • an auxiliary device 4 is interposed. It consists essentially of an electronic valve 5 with a line-side connection 6 for the series choke and a line-side connection 8 for the dimmer 3 leading to the control electrode 7 of the electronic valve 5.
  • Further line-side connections 9 and 66, which are independent of the electronic valve, are for the center conductor M and provided for connecting the outer conductor L1. The potential of the center conductor is led to the connection 10 on the lamp side.
  • the output of the electronic valve 5 is connected to a lamp-side connection 14.
  • the electronic valve 5 is shown as a triac with a capacitor 11 connected upstream on the control side.
  • this capacitor 11 can have a capacitance of approximately 01.1 J, 1.F. It differentiates the control voltage so that a voltage jump from the phase gating dimmer leads to the ignition of the triac 5.
  • auxiliary device 4 also includes the devices for an inductive quick start device 12 of a known type, a high-voltage coil 13 can be easily integrated with it. Between the mains-side connection 9 for the center conductor M and the lamp-side connection 14 of the electronic control valve 5, the high-voltage coil 13 is advantageously switched on, which is coupled to the iron core 15 of the inductive quick start device 12.
  • the high-voltage coil 13 can advantageously be designed so that it outputs a voltage in the range of 600 to 1500 volts at its terminals.
  • the inductive quick start device 12 is advantageously in one shared housing.
  • the quick-start device 12 with its primary winding 16 is switched on between the network-side connection 9 for the center conductor M and the network-side connection 66 for the outer conductor L1.
  • a connection to a further connection 19 and a further connection to the lamp-side connection 14 of the electronic control valve 5 is formed from the other secondary winding 18.
  • a current limiting resistor 20 of approximately 3.3 megohms can be switched on.
  • the grounded lamp housing, which is symbolized by 21, can serve as a further starting aid for the low-voltage fluorescent lamp 1.
  • the load circuit of the low-voltage fluorescent lamp is formed on the mains side by an outer conductor L1 connected to the ballast choke 2 and by the center conductor connected to the connection 9, the potential of the outer conductor, designated L2, also being supplied to the dimmer 3, as a result of which the low-voltage fluorescent lamp is at its brightness can be regulated.
