Definitions

  • This electronic ballast for self ballasted lamps and other gas discharged lamps with or without filaments perform with high energy efficiency and high quality meeting safety requirements and performance requirements as envisage in IS 15111 Part 1 and 2 and also IEC 60968-Safety requirements and IEC 60969-Performance requirements.
  • This technology is used to produce Ballast with various wattages.
  • These lamps will perform with high efficiency with one filament or two filament or without any filaments.
  • Transistors with various ratings can be used.
  • Diodes with different Voltage ratings and different current carrying capacities can be used.
  • Zinar diodes can be used instead of diodes.
  • Ferrite cores with different ratings and shapes can be used.
  • A4 rectifying diodes convert input AC power to DC power.
  • A2 rectifying diodes amplify Dc voltage.
  • G4 capacitor and M2 Diac make circuits ON.
  • connecting rods with less resistance can be used to function lamps.
  • S2 resistance prevents shorting of the circuit.
  • Y2 -Field effect transistor can be used to raise sensing capacity of the circuit.
  • Y4 transistor stops high frequency power.
  • B4 diodes convert secondary coil power to DC power
  • T4 resistance reduces the power flow in the M4 Diac
  • F6 resistance helps to make circuit stable, when the circuit function abnormally.
  • F4 resistance speed up the Cut off functioning, when the circuit functions abnormally at lower voltage
  • F2 resistances help transistors to function very stably
  • D4 coils of R2-0-Core produces high frequencies and also controls transistors.
  • T2 resistance functions parallel to P2 diodes and makes output high frequency and equalises peak to peak.
  • E2 resistances increase the voltage and current of H2- secondary of C2-Ee-Core coils.
  • H4 coil and J2 capacitors helps to get stable high frequency power at output.
  • A4 Diode converts input AC power to DC power. Resistance is connected serially to input power flow of rectifying circuit. This will minimise the possibility of circuit becomes short.
  • DC Voltage is boosted by B2 Electrolytic Capacitor and A2 Diodes.
  • K4 diodes enhance the functioning of D2 transistors and reduce transistor heat.
  • Resistances are connected parallel to P2 diodes which make peak to peak equaliser in high frequency power.
  • E2- Resistance helps to reduce the flow of current in lamps when the circuit is ON.
  • High frequency power is controlled by D4 winding coil of R2-0- Chore.
  • J4 Capacitors filter Dc currents.
  • J2 Capacitor charges high frequency power and then discharge and lights the lamps.
  • H4-Coil produces high frequency power. STAGE 4 -Even if the circuit functions abnormally, the circuit is maintained without any defects
  • FFT transistor is made ON by the secondary H2 coil of C2-EE-Core.
  • Y4 transistor will also made ON and stops the High frequency Power.
  • L4E4 capacitors help the stable functioning of Transistors.
  • M4Diac helps the FFT transistors for the initial power flow.
  • B4 diode converts high frequency power to DC power. This power is limited by M2-Resistance.
  • T4-Resistance limits the power flow of Diac.
  • F4 Resistor regulated the functioning of transistors.

Abstract

L'invention concerne un ballast électronique, qui est utilisé pour des lampes à lumière mixte et autres lampes à décharge de gaz avec ou sans filament. La taille de tous les composants du circuit peut être vérifiée; le circuit fonctionne à des tensions et fréquences variables; les lampes peuvent être allumées avec 2 ou 4 fils reliés à la sortie du ballast électronique; les lampes seront éclairées même s'il n'y a aucun filament, s'il y a un filament, deux filaments ou des tiges de connexion en lieu et place de filaments.
