Definitions

  • the present invention relates to a power variation system in an electrical circuit comprising one or more electric lamps.
  • the purpose of this device is to vary the lighting power as a function of parameters such as the time or the external brightness. It is especially intended to control a public lighting network or a lighting network in workshops.
  • Devices for varying the power of lamps using electromechanical dimmers such as rheostats or toroidal transformers.
  • Electronic variators are also known using triacs.
  • electromechanical drives can in some cases have a low efficiency and generate electromagnetic interference. In addition, they require a complex servo motor system to react to external parameters. Electronic variators are also sensitive to network disturbances, in particular to overvoltages which may appear during a thunderstorm.
  • the known devices are not suitable for certain types of lamps which necessarily require maximum power on ignition. This is particularly the case for certain lamps of the metal vapor type such as sodium lamps or mercury lamps stabilized by standard devices.
  • French patent FR-1378274 proposes an apparatus using an autotransformer and a switch to obtain attenuation of the light intensity, by reducing the supply voltage of the, or of the lamps supplied, independently of the lamps to be attenuated. This type of device cannot be used to vary the intensity of discharge lamps.
  • the present invention aims to remedy this drawback by ensuring maximum power on the network at the time of ignition and for a sufficient time for the lamps reach their operating speed, regardless of the values of the control parameters.
  • the present invention has many other advantages.
  • the device according to the invention is very insensitive to disturbances from the network, does not create electromagnetic interference and has good performance.
  • the network When the primary winding is short-circuited, the network is supplied at its maximum power.
  • the coil (9) of the inverter (2) is controlled by the timer (6).
  • the timer (6) establishes a fugitive contact between the point (11) and the phase. This contact is maintained for an adjustable duration and determined by the characteristics of the lamps used on the lighting network. It can be set by way of example at 120 seconds for SHP type lamps.
  • the timer After this delay, the timer returns to its rest position and ensures contact between the phase and the point (12).
  • the point (12) is also connected to the inverter (4) which can be controlled by a mechanical or electronic clock.
  • This inverter (4) supplies the coil (13) or the coil (9) of the electromagnetic inverter (2) depending on its position.
  • the coil (9) When the coil (9) is energized, the secondary winding of the injector (5) is short-circuited and the network is therefore supplied at its maximum power.
  • the power available on the network can take two values depending on the state of the inverter (3).
  • This inverter (3) can also be controlled by a pendulum, feeds the coil (14) or (15) of the electromagnetic inverter (1).
  • the device may include an injector having several intermediate sockets.
  • a second injector is inserted between the electromagnetic inverter (1) and the electromagnetic inverter (2).
  • This second injector allows fine adjustment of the minimum and intermediate values.
  • one or both of the reversers (3, 4) can be controlled by devices sensitive to external lighting.
  • the inverter (4) may consist of a photoelectric cell controlling an electromagnetic or electronic relay whose triggering threshold will correspond to dusk.
  • the inverter (3) can also consist of a photoelectric cell controlling a relay, the triggering threshold of which will correspond to a higher luminosity, in order to modulate the lighting as a function of the external luminosity.
  • Another variant consists in replacing the electromagnetic inverters (1) and (2) with three-phase inverters in order to control a three-phase network.
