Definitions

  • Gas discharge lamps with electronic ballasts are preferred because of their low power consumption compared to conventional incandescent lamps with the same luminous efficacy. For example, fluorescent lamps with about 20% power consumption can achieve the same luminous efficiency.
  • immers are also used to reduce the brightness of the lamps. This desire exists not only to save additional energy, but also to reduce the illuminance e.g. B. set in the night.
  • the object of the invention is to be able to select a reduced light intensity in addition to a maximum light intensity in a simple manner.
  • bistable switching system flip-flop
  • the two switching states correspond to different lamp currents and thus different brightness values.
  • Such a flip-flop system can advantageously be accommodated in a simple manner in the electronic ballast.
  • bistable switching system controls several electronic ballasts in groups.
  • the invention further proposes a short-time switch, for. B. in the form of a push button in the circuit, which interrupts so briefly that the lamp does not go out, but the bistable switching system responds to the interruption.
  • Figure 1 shows an example embodiment in a schematic representation of how a device according to the invention could be constructed.
  • the gas discharge lamp (lamp 1) is connected to the network R, S via an electronic ballast.
  • the bistable switching system 6 In between is the bistable switching system 6 and a light switch 8 with which the lamp 1 can be switched on. As soon as the switch 8 is opened briefly after the first switch-on, the bistable switching system switches to its second switching position and thus influences the lamp current through the lamp 1 via the electronic ballast 2.
  • a short-term interrupter is arranged as a button 13 in the feed line R, which z. B. can be designed as a push button. If this button 13 is actuated, there is a power interruption in the millisecond range, short enough to avoid lamp 1 from being annoyingly extinguished, but long enough to allow bistable switching system 6 to respond.
  • a control element 10 is provided which, in the manner of a "dimmer", reduces the lamp current as desired.
  • FIG. 2 shows a group arrangement with, for example, 3 lamps 1, which are supplied by the electronic ballasts 3, 4 and 5.
  • the bistable switching system 7 acts on all 3 electronic ballasts 3, 4 and 5, however, a separate control element 11 is provided for setting the reduced brightness for the electronic ballast 3.
  • control element 12 acts as a group on the electronic ballasts 4 and 5.
  • bistable switching system 6, 7 can be integrated in the electronic ballasts 2, 3, 4, 5 or in one of the same.
  • control elements 10, 11, 12 could also be integrated in the electronic ballasts.
  • This exemplary embodiment shows the mode of operation of the switching system 6, 7 on a ballast 27 which contains a stray field transformer 30.
  • ballast 27 can be replaced by appropriate capacitive elements in connection with semiconductor switches.
  • the field of application of the present invention thus extends not only to a ballast 27 with a stray field transformer 30, but to ballasts of any type, regardless of their construction in detail.
  • a lamp housing which carries a translucent lens 22.
  • a fluorescent lamp 23 with preheatable electrodes 24, 25 and a reflector 26 is arranged in the housing.
  • the lamp 23 is connected to an electrical lead via a ballast 27 and a switch 39.
  • a winding 29 connected to the lamp circuit is used to operate the fluorescent lamp 23 with reduced brightness.
  • a stray field transformer 30 with primary winding 31, secondary winding 32 for the lamp 23 and secondary heating winding 33, 34 for the lamp electrodes 24, 25 are in the lamp housing as well as the winding 29, which is arranged in series with the secondary winding 32 of the stray field transformer.
  • the windings of the stray field transformer 30 are arranged on a jacket core, with scattering paths 36, 37 being arranged between the primary winding 31 connected to the input terminals E 1, E 2 and the windings 32, 33, 34.
  • the ends of the heating windings 33, 34 are connected to the terminals H1 to H4, which in turn are connected via conductors to the electrodes 24, 25 of the fluorescent lamp.
  • the electrical supply line to the lamp housing is expediently provided with a mains plug 28.
  • the winding 29 is preferably connected to one end of the secondary winding 32 for the lamp and to one end of the heating winding 33 and can be bridged by a switch 38.
  • the winding 29 is expediently designed as a choke 41 with a closed magnetic core and accommodated in the ballast 27.
  • the winding ends of the choke 41 are connected to the terminals S1, S2.
  • One end of the secondary winding 32 of the stray field transformer 30 is also connected to the terminal S 1 and one end of the heating winding 33 is connected to the terminal S 2 via the terminal H 3.
  • the switch 28, which is attached to the lamp housing, is closed to achieve full brightness, so that the inductance 29 is bridged.
  • the lamp electrodes 24, 25 are strongly preheated.
  • the fluorescent lamp 23 is then ignited by the stray field transformer only after sufficient preheating.
  • the duration of the preheating adapts to the respective ambient temperature. After the lamp is ignited, the heating current drops. If the lamp is operated with full brightness, the heating current is reduced to a level which does not impair the life of the lamp. When the brightness is reduced, the preheating increases again automatically, so that the electrodes are sufficiently heated even in low-load operation.
