Single secondary dimming inverter/ballast for gas discharge lamps

摘要: A highly efficient, energy saving ballasting and transfer circuit, utilizing a single high frequency inverter ballast unit, capable of powering multiple lamp loads from any direct or alternating electric power source, comprises current feedback in combination with leakage transformer, which operates to permit coupling the unit number lamps, particularly gas discharge type. The transformer can lamps source which, because its linear function, achieves controlled light output proportional input. Thus, an excellent dimming capability is achieved. It important note that this special case certain type multi-path where only one secondary coil used achieve same capabilities embodiments.
