As shown in Figure 2, the workflow diagram of the Intellectualized controller of the described HID electric ballast of the utility model operating state, describe in detail as follows:

Flow process 01, the initialization of microprocessor;

Flow process 02 detects whether overvoltage of input voltage, whether ballast is operated in over-temperature condition, finds overvoltage or over-temperature condition, thinks anomaly, and ballast cuts out automatically, and LED lamp indication fault is waited for voltage and temperature just often, works on;

Flow process 03 detects to treat whether switch is pressed, and presses if treat switch, and need are back to 02 after treating that switch is opened; Otherwise get into 04;

Is flow process 04 opened igniting, and whether pre-detection opens a way, short circuit, if detect open circuit or short circuit, then ballast cuts out driving, record igniting times N (N=X? Can be according to requirements set), if N reaches igniting number of times X, ballast automatically locks, and show state; If N do not reach set point X, the Y that then delays time (can according to requirements set) second, be back to 02; Otherwise get into 05;

Flow process 05, whether the inspection bulb is lighted, and through detecting lamp power, detects and waits the bubble operating state, does not light and gets into 18,19,21,02 circulation, otherwise get into 06;

Flow process 06, beginning preheating constant current output, because the characteristic of bulb, during startup, modulating voltage is low, makes lamp current very big, causes the damage of bulb and ballast easily, ballast is used constant current technology thus, avoids causing the damage of bulb and ballast;

Flow process 07 detects the bulb model, and the bulb model is judged in preheating constant current time-delay;

Flow process 08 detects modulating voltage, lamp current, judges the bulb model, satisfies 600W as if modulating voltage, lamp current, gets into 09; Satisfy 1000W, get into 11;
