Definitions

  • the invention belongs to the electrical technology and electronics sector and refers to an electronic circuit, which is used for the initiation and operation of sodium and mercury lamps with simultaneous saving of energy.
  • ballast for the initiation and operation of sodium and mercury lamp is the use of ballast, starter.
  • the two above elements are parts of the electrical circuit that is connected with the electrification network in which the ballast is connected in line to the lamp while the starter is connected in parallel. In this case the lamp brings glow threads.
  • Cosf takes values from 0,33 - 0,51, depended to the ballast producer and the power of lamp.
  • the mentioned before ballast also causes the appearance of electromagnetic parasitises and has great volume and weight as well as produces characteristic noise during operation.
  • the present invention intents to replace the electrical circuit of initiation and operation of sodium and mercury lamps with an electronic device that will eliminate the use of the ballast and the starter as well as the glow threads in the lamps. In other words it intends to the manufacture and use of an electronic circuit that will do the initiation and operation of the lamp much more efficient and constant, less complicated and absolutely noiseless.
  • the sodium and mercury lamps are also exempted from the glow threads, a fact that will cause reduction of the cost of the lamps during their production.
  • the electronic circuit of initiation and operation of sodium and mercury lamps uses electric energy from the electrification network 220V/50Hz and it contains electronic absorption parasitises and vibrations filter that emanate from the high frequency generator, that prevents at the same time the transmission of these to the electrification network.
  • the high frequency generator dispatches to the entry of the driver transistor the basic frequency, according to the power of lamp 70 up to 400W.
  • the driver transistor that receives the basic frequency supplies the electronic transformer with high frequency ferrite with more or less current and with this way the lamp is provided with the most excellent conditions of operation that increase the performance of electric energy.
  • the basic generator frequency is 27KHz because with this value excellent conditions are achieved that are required for the constant and long-lasting operation of sodium and mercury lamps.
  • the high frequency generator is connected in parallel is part of the electronic alternate current AC/DC transformer, which changes the alternate current to continuous and has filter for continuous current.
  • the high frequency ferrite transformer has three threads. From these threads the one is the superior and two are secondary and all are galvanized and insulated between them.
  • the secondary threads are: one small and one big. The superior, due to great frequency raise the big one which turns on the lamp.
  • the small secondary is part of a control operation circuit of the lamp which is in charge for the interruption of current supply to the big secondary in case something happens away from the normal operation (short-circuit, fracture of lamp, current leak etc).
  • An electronic circuit of initiation and operation of sodium and mercury lamps according to the present invention presents a lot of advantages.
  • Basic advantage of the use of the electronic circuit is the economy at the consumption of electric energy and at the replacement of lamps, at the use of electrical - electronic elements and at the lamp manufacture.
  • the consumption of electric energy is decreased up to 75% without the simultaneous reduction of the performance of the lamp, because the suppression of the ballast and the great number of conductors (cables) eliminate the appearance of energy loss due to heating.
  • the supply of the electronic ferrite high frequency transformer with current becomes ideal, so that excellent operation conditions are provided to the lamp that increase the performance of electric energy.
  • the ideal supply is combination of frequency that is given by the generator and the power of the connected lamp.
  • the replacement of the sodium and mercury lamp becomes more seldom because the duration of life until its natural destruction is increased.
  • ballast disappears unpleasant noises and exempts the circuit from dangerously electromagnetic parasitises.
  • Picture 1 shows the electrical drawing with the lamp (B), the electronic circuit (A) of initiation and operation of the sodium and mercury lamps with saving of energy and the source of electric current (C) that is not other than the electrification network.
  • Picture 2 shows the entry of tendency of the alternate current (1) from the supply network, then the current passes through the combination of ballasts C1, C2 and inductors L1, L2 which constitute a filter of parasitises (2). From there it passes through the "bridge" IC1 (3) where it is transformed from alternate to continuous. Then the ballast C3 (4) stabilises the oscillation that produces the "bridge” and with the resistance R1 (5) is performed the required drop of tendency in order that the one with the suitable filters (6) at ballasts C4 and C5 becomes constant from stabilizer IC2 (7).
  • the constant current passes from the oscillator (8) which is high requency current generator, at class of 27kHz.
  • the oscillator is a common of trade element like the transistor or the resistances.
  • the capacitor C6 for the regulation of transistor operation frequency.
  • the tendency at utmost (13) of the lamp is given to a terminal by each side of the lamp without the need of glow at the resistances that has the lamp at utmost.
  • control circuit (14) which has the small secondary inductor S2 of electronic ferrite transformer at one utmost.
  • the small secondary ballast S2 receives the tendency increase that exists and gives a command via the control circuit (14) to interrupt the current supply to the lamp and thus the operation of circuit is rendered absolutely safe for the user.
  • transistor resistance R5 (15) is used and for the regulation of transistor output tendency resistance R6 (16) is used.
