Be the workflow diagram of the control device of HID electric ballast operating state shown in accompanying drawing 2, detailed is described below:

Flow process 01, the initialization of microprocessor and PWM chip;

Flow process 02, Program time delay 500ms, this moment, the HID electric ballast just started, and inner direct voltage is unstable, needs time-delay 500ms, waits for that voltage all in the HID electric ballast is stable;

Flow process 03, opening point are fought and write down the igniting times N: microprocessor sends ignition signal to the PWM chip, PWM chip output high-frequency PWM ripple, and HID electric ballast lamp current produces resonance potential, and microprocessor is accomplished the record igniting times N of once lighting a fire;

Flow process 04, judge whether lamp is lighted: the lamp operating state detects current detecting bulb operating state, and microprocessor is collected detection signal, if do not light, gets into flow process 05, otherwise gets into flow process 10;

Flow process 05, close output: the judgement lamp is not lighted in the flow process 04, then closes the output of PWM chip, stops the output of electric ballast;

Flow process 06 judges whether the igniting times N equals 4, if N equals 4, shows that the igniting number of times reaches the set point lamp and also do not light, and then gets into flow process 07; If N is not equal to 4, show that the igniting number of times does not also reach set point, will continue igniting;

Flow process 07, shutdown: the igniting number of times reaches 4 back lights also not to be lighted, and then closes the output of electric ballast;

Flow process 08, LED is bright entirely: after the flow process 07, LED is bright entirely, and indicator light breaks down;

Flow process 09, delay procedure: judge in the flow process 06 that N is not equal to 4, promptly lamp is not lighted the igniting number of times that does not yet reach setting, then carries out delay procedure.Lamp is not lighted always; Then always in 03,04,05,06,09 circulation of flow process; Delayed time respectively 15 minutes, 5 minutes, 5 minutes, having constituted with igniting for the first time is 15-20-25 minute spark delay of basic point, and effective the has avoided excess impact to bulb to cause damages or the life-span reduces;

Flow process 10 provides initial power: after flow process 04 judged that lamp is lighted, microprocessor sent instruction for the PWM chip, with certain frequency drives half-bridge circuit, makes the initial power of the power output of electric ballast a setting;

Flow process 11; The power adjustment; The LED flicker: microprocessor constantly reduces for the frequency of oscillation of PWM chip and constantly detects power output through the lamp state detection circuit; The power output that makes electronic ballast rises to full power with the steady rate of 50W/30S, the LED lamp flicker of the corresponding power shelves of memory value this moment;

Flow process 12, preheating finish: this stage that bulb is illuminated to full power belongs to warm-up phase, lamp power rise to full power and stable after, preheating finishes;

Flow process 13, read memory value: microprocessor comprises EEPROM, can write the last operating power state of electric ballast last time, after preheating finishes, reads the performance number of remembering among the EEPROM;

Flow process 14; Power adjustment: microprocessor constantly increases for the frequency of oscillation of PWM chip or reduces and constantly detect power output through the lamp state detection circuit, and the power output that makes electronic ballast rises with the steady rate of 50W/30S or is decreased to the performance number of memory;

Flow process 15, power are closed the power adjustment after adjusting to memory value;

Flow process 16, whether testing is normal: microprocessor is through the state detection circuit of HID electric ballast, and whether the work that detects the HID electric ballast is normal; If undesired, then the HID electric ballast extinguish and Returning process 03 light a fire again;

Flow process 17, actuation of keys, write memory value: microprocessor detects actuation of keys; If actuation of keys writes memory value at EEPROM, and Returning process 13 reads memory value; Carry out the power adjustment to flow process 14 then, make the work of HID electric ballast, accomplish the light modulation action to power by key assignments; If do not detect actuation of keys, operate as normal then;

Flow process 18; Operate as normal: flow process 16,17,18 have constituted a circulation; In HID electric ballast operate as normal, constantly detect actuation of keys and operating state, in case actuation of keys occurs or detect job failure then turn back to corresponding flow process at once handling.
