Definitions

  • the invention relates to a busbar for lighting fixtures, in particular for low-voltage halogen incandescent lamps, fluorescent lamps, discharge lamps and the like, with at least two mutually insulated rail conductors, in which the mains voltage is converted via a converter to the voltage assigned to the lamp to be switched on.
  • the invention has for its object to further develop a busbar for the lighting fixtures mentioned above so that the current-carrying parts of the busbar can be dimensioned smaller.
  • the invention is characterized in that the converter is designed as a control device which converts the mains voltage into a high-frequency voltage on the rail conductors, and that at the tap point of each lighting fixture on the busbar or on the lighting fixture, a high-frequency transformer or an HF Throttle is arranged, which converts the voltage applied to the rail conductors into another voltage that is adapted to the lighting fixture to be switched on in each case.
  • the essence of the invention is that now instead of the conventionally used low-voltage transformers, which are normally present at 220 volt busbars and z. B. are assigned to a lamp, instead, small-sized high-frequency transformers can be used, which are small. They are 30 times smaller than conventional low-voltage transformers.
  • the advantage of the invention is that a relatively harmless high-frequency voltage is transmitted via the current-carrying parts of the busbar, which results in a contact voltage which is harmless because dangerous frequency conduction through deeper tissues of the human body is avoided in the frequency ranges used.
  • the transformer according to the invention into the adapter, ie into the coupling point at which the lighting fixture attaches to the busbar.
  • Another advantage is that due to the voltage used on the busbar, only a small power loss can be visualized. This reduction is achieved in two areas, firstly there is a reduction in the transport power loss along the conductor rail and secondly the power loss that occurs at the switch-on point of the lamp body on the conductor rail is reduced - so that heating and premature wear of the contacts and a risk of arcing the assembly or implementation of the luminaire body is avoided when the rail is live.
  • Another important advantage of the invention is that fluorescent lamps can be connected to the busbar system according to the invention with little effort, because instead of the large-sized iron core-carrying chokes, a small-sized HF choke can now be used. Again, the dimensions of such a choke are reduced by a factor of 30 compared to conventional iron core chokes.
  • control device which is used to generate the high-frequency voltage, only has to be present once in the busbar, and its dimensions are so small that it can be integrated into the busbar itself. It is also possible to integrate this control device into an adapter piece in the busbar.
  • busbar system it is possible to operate the busbar system according to the invention not only with two conductors, but also with several conductors, the conductors going beyond two being used for the separate control of the individual lighting fixtures.
  • tapping points on the control device it is also possible to bring out additional tapping points on the control device in order to simplify the control circuit for a fluorescent lamp.
  • the previously mentioned tapping points on the control device also serve to produce a separate starter circuit.
  • the AC line voltage of 230 volts rms, 50 Hertz is introduced into the control device 1. It arrives in a rectifier network 2, where it is first rectified. Then it reaches an inverter 3, where it is converted to a higher frequency, preferably in the range from 20 to 200 kHz.
  • the lower range of 20 kHz should not be undercut, because otherwise the hearing range will be reached and the upper range of 200 kHz should not be exceeded, because otherwise the high-frequency power losses in the busbar system become too large.
  • a frequency in the range from 30 to 50 kHz is preferred here.
  • an alternating voltage of approximately 230 volts is then effectively present on the rail conductors 5, 6 at a frequency in the range from 20 to 200 kHz.
  • the respective connection takes place via tapping points 7, 8, of which lines 9, 10 each lead into a high-frequency transformer 11.
  • the HF transformer is small and has for example with a power of 100 VA, 40 kHz dimensions of 2 x 2 x 2 cm and a ferrite core.
  • the respective lighting fixture 13 is connected to the output of the HF transformer and, in a preferred exemplary embodiment, is designed as a low-voltage halogen incandescent lamp.
  • the number of lighting fixtures that can be connected depends on the output power of the control device 1.
  • the fluorescent lamp 15 is connected via an RF choke, the choke in turn the small dimensions of z. B. 1.5 x 2 x 2 cm with a power of 58 watts.
  • the fluorescent lamp 15 is associated with a starter 15a known per se.
  • compact lamps with an output of 5 watts to 36 watts can also be connected, the RF chokes used being dimensioned correspondingly smaller for this purpose.
  • a high-pressure lamp 16 is connected via a further HF choke 18 and an ignition circuit 17.
  • the output of such high-pressure lamps can be in the range between 35 and 250 watts and the type of high-pressure lamps can be different, e.g. B. high pressure sodium lamps, high pressure mercury lamps or metal halide lamps.
  • FIG. 2 shows a detailed circuit diagram of a control device 1 according to FIG. 1 as an exemplary embodiment.
  • the AC mains voltage 4 is fed via a radio interference suppression circuit 19 to a bridge rectifier 20, which outputs its pulsating DC voltage via a charging capacitor 21 to a corresponding power unit 23.
  • the power section is in the present embodiment, for. B. executed with mutually connected transistors which are controlled by a common control electronics 22.
  • an artificial HF zero point is formed via, for example, two capacitors 24 connected in series. At this artificial zero point, one rail conductor 5 attaches, while the other rail conductor 6 attaches to the output of the power section 23.
  • the artificial center of conduction is achieved by a double bridge equipped with transistors.
  • two power sections 23, 23 ' are connected in inverse relation to one another, the transistors shown here being designed as a bridge circuit, with transistors in the bridge diagonal always being connected through while the transistors of the other bridge diagonal are blocked and vice versa.
  • a further conductor or a plurality of further conductors is provided in another embodiment, not shown in the drawing, one or more further conductors being provided for dimming the corresponding lighting fixtures, the control information being provided via these further conductors the assigned dimming circuits are transmitted.
