Control system having lighting function and plasma generation function

A control system having a lighting function and a plasma generation function, the control system comprising:

• a power conversion unit configured to convert an AC power into a DC power such that a power ripple twice a frequency of a full-wave rectified input power is generated;
• a lighting control unit configured to control turning on and off of an LED lighting lamp by turn-on/turn-off operations of a transistor electrically connected to the power conversion unit, and keep a current supplied to the LED lighting lamp constant;
• a photocoupler unit including a first photocoupler electrically connected to the power conversion unit and the lighting control unit to detect a full-wave rectified DC power to turn on the transistor by an on-operation, and a second photocoupler electrically connected to the power conversion unit to detect a full-wave rectified DC power to perform an on-operation;
• an oscillation frequency generation unit electrically connected to the second photocoupler to generate an oscillation frequency when the second photocoupler performs the on-operation;
• a plasma electrode configured to receive an amplified high voltage to generate plasma by corona discharge;
• and
• a high voltage supply unit electrically connected to the oscillation frequency generation unit to receive the oscillation frequency to induce a high voltage, and amplify the induced high voltage to supply the induced high voltage to the plasma electrode.
