According to Fig. 2-Fig. 7, describe the specific works principle of the illumination control circuit of this preferred embodiment below in detail.
When user presses mechanical switch S5, power supply BT2 switches on to Master control chip IC1, Master control chip IC1 and peripheral circuit thereof are realized DC decompression function, and power circuit is by the stable output 3.3V of pressure regulation chip IC 3 voltage, simultaneously by the stable output of diode D5 3V reference voltage.At this moment the square wave that the RC2 pin output duty cycle of the brightness adjustment control chip IC 4 of adjusting control circuit 14 is 100%, the D/A converting circuit forming through resistance R 3, resistance R 4, resistance R 7, capacitor C 5 and capacitor C 6, to first input end (the being negative input end) input ratio of feedback chip IC 2 compared with reference voltage; Electric current is through excessive power White LED D1 simultaneously, by resistance R 7 and resistance R 8, form sampled voltage, be input to second input (being positive input terminal) of feedback chip IC 2, when sampled voltage equates with benchmark voltage, the stable output of output of feedback chip IC 2, the Vout pin that is Master control chip IC1 receives stable feedback command, main control circuit 13 steady operations, and the White LED D1 of lighting device normally lights.
As user does not press mechanical switch S5, unclamp on earth, the White LED D1 of lighting device realizes tactics and lights.As user presses mechanical switch S5 on earth, the White LED D1 of lighting device is in normal illumination state.
When the White LED D1 of lighting device 10 is during in normal illumination state, can carry out by adjusting control circuit 14 control of White LED D1 work gear.When user presses once (be S11 closure/disconnection once) and hold time and be less than in the first setting-up time (as 0.5 second etc.) of electronic switch S11, when electronic switch S11 is closed, the RA3 pin of brightness adjustment control chip IC 4 is pulled to low level, and hold time in setting-up time, at this moment the square wave that the RC2 pin output duty cycle of brightness adjustment control chip IC 4 is 40%, through resistance R 3, resistance R 4, resistance R 7, the D/A converting circuit that capacitor C 5 and capacitor C 6 form, to feedback chip IC 2 first input end (being negative input end) input ratio compared with reference voltage, electric current is through excessive power White LED D1 simultaneously, by resistance R 7 and resistance R 8, form sampled voltage, be input to second input (being positive input terminal) of feedback chip IC 2, when sampled voltage equates with benchmark voltage, the stable output of output of feedback chip IC 2, the Vout pin that is Master control chip IC1 receives stable feedback command, main control circuit 13 steady operations, benchmark voltage while being less than White LED D1 normal illumination due to benchmark voltage, therefore the operating current of White LED D1 diminishes, realized the gearshift of White LED D1, the work gear of White LED D1 is turned down.As again pressed electronic switch S11 once and holding time, be less than in the first setting-up time, the RC2 pin of brightness adjustment control chip IC 4 can output duty cycle be other different square waves, and other gears of realizing White LED D1 regulate.
When the White LED D1 of lighting device 10 is during in normal illumination state, also can carry out the control of multiple monochromatic LEDs by adjusting control circuit 14.When pressing electronic switch S11 once and hold time, user is greater than the second setting-up time (as 1 second etc.), when electronic switch S11 is closed, the RA3 pin of brightness adjustment control chip IC 4 is pulled to low level, and hold time and be greater than the second setting-up time, at this moment the RC2 pin of brightness adjustment control chip IC 4 output zero level, to the first input end input zero balancing reference voltage of feedback chip IC 2, electric current is through excessive power White LED D1 simultaneously, by resistance R 7 and resistance R 8, form sampled voltage, be input to second input (being positive input terminal) of feedback chip IC 2, when sampled voltage equates with zero balancing reference voltage, be that sampled voltage is 1 o'clock, the Vout pin of Master control chip IC1 receives stable feedback command, main control circuit 13 quits work, White LED extinguishes.The simultaneously RA0 pin of brightness adjustment control chip IC 4 output high level, lights monochromatic LED D2 by the switching tube Q3 of the monochromatic LED control circuit in Fig. 5, realizes normally the lighting of monochromatic LED of lighting device 10.
When the monochromatic LED of lighting device 10 is normally lighted (in mechanical switch S5 closure), also can carry out by adjusting control circuit 14 control (being the switching between multiple monochromatic LEDs) of multiple monochromatic LED gears.When user presses once (be S11 closure/disconnection once) and hold time and be less than the 3rd setting-up time (as 0.5 second etc.) of electronic switch S11, when electronic switch S11 is closed, the RA3 pin of brightness adjustment control chip IC 4 is pulled to low level, and hold time in setting-up time, brightness adjustment control chip IC 4 switches to RA1 pin output high level, pin RA0 output low level, the RC2 pin of brightness adjustment control chip IC 4 is still exported zero level, to the first input end input zero balancing reference voltage of feedback chip IC 2, main control circuit 13 still quits work like this, White LED extinguishes.The RA1 pin output high level of brightness adjustment control chip IC 4, lights monochromatic LED D4 by the switching tube Q10 of the monochromatic LED control circuit in Fig. 6, realizes the gear switch (being that monochromatic LED D2 switches to monochromatic LED D4) of the monochromatic LED of lighting device.
While so having realized White LED D1 normal illumination, switch to monochromatic LED, and realize the switching of different monochromatic LEDs.
When the monochromatic LED of lighting device 10 is normally lighted, (in mechanical switch S5 closure), also can switch to White LED D1 by adjusting control circuit 1.When pressing electronic switch S11 once and hold time, user is greater than the second setting-up time (as 1 second etc.), when electronic switch S11 is closed, the RA3 pin of brightness adjustment control chip IC 4 is pulled to low level, and hold time and be greater than the second setting-up time, at this moment the RC2 pin square wave that output duty cycle is 100% again of brightness adjustment control chip IC 4, to feedback chip IC 2 first input end input ratio compared with reference voltage, electric current is through excessive power White LED D1 simultaneously, by resistance R 7 and resistance R 8, form sampled voltage, be input to second input (being positive input terminal) of feedback chip IC 2, when sampled voltage equates with benchmark voltage, the stable output of output of feedback chip IC 2, the Vout pin of Master control chip IC1 receives stable feedback command, main control circuit 13 steady operations, the White LED D1 of lighting device normally lights.RA0 pin and the RA1 output low level of brightness adjustment control chip IC 4, realize the monochromatic LED D2 of lighting device 10 and extinguishing of monochromatic LED D4 simultaneously.
So, having realized monochromatic LED switches to White LED D1 and throws light on.
As the White LED D1 of lighting device during in non operating state (mechanical switch S5 disconnect in), still can carry out the switching between control and multiple monochromatic LED of multiple monochromatic LEDs by adjusting control circuit 14.When user presses electronic switch S11 and maintains, the public negative pole of integrated circuit is connected with the negative pole of BT2 by diode D6, electronic switch S11, circuit is started working, the RA3 pin of brightness adjustment control chip IC 4 is pulled to low level and maintains, brightness adjustment control chip IC 4 switches to RA0 pin output high level, pin RA1 output low level, the RC2 pin of brightness adjustment control chip IC 4 is still exported zero level, to the first input end input zero balancing reference voltage of feedback chip IC 2, main control circuit 13 still quits work like this, and White LED extinguishes.By the switching tube Q3 of the monochromatic LED control circuit in Fig. 5, light monochromatic LED D2 simultaneously.Now, because S11 maintains conducting state, the monochromatic LED of lighting device is realized and is continued to light.
Can be by adjusting control circuit 14 control (being the switching between multiple monochromatic LEDs) to multiple monochromatic LED gears.When user's cut-off/close electronic switch S11 once, and maintain and press, and be less than the 4th setting-up time (as 0.5 second etc.) with the time interval of last cut-off/close electronic switch S11, because capacitor C 13 and capacitor C 16 have electric power storage effect, within the short time of power-off, still can maintain IC4 normally works, when the RA3 pin of brightness adjustment control chip IC 4 is pulled to low level again, brightness adjustment control chip IC 4 switches to RA1 pin output high level, pin RA0 output low level, the RC2 pin of brightness adjustment control chip IC 4 is still exported zero level, to the first input end input zero balancing reference voltage of feedback chip IC 2, main control circuit 13 still quits work like this, White LED extinguishes.The RA1 pin output high level of brightness adjustment control chip IC 4, lights monochromatic LED D4 by the switching tube Q10 of the monochromatic LED control circuit in Fig. 6, realizes the gear switch (being that monochromatic LED D2 switches to monochromatic LED D4) of the monochromatic LED of lighting device.
As user, cut-off/close electronic switch S11 is once again, and maintain and press, and be less than the 4th setting-up time (as 0.5 second etc.) with the time interval of last cut-off/close electronic switch S11, because capacitor C 13 and capacitor C 16 have electric power storage effect, within the short time of power-off, still can maintain IC4 normally works, the RA3 pin of brightness adjustment control chip IC 4 is pulled to again low level and maintains, brightness adjustment control chip IC 4 switches to RA0 pin output high level, pin RA1 output low level, the RC2 pin of brightness adjustment control chip IC 4 is still exported zero level, to the first input end input zero balancing reference voltage of feedback chip IC 2, main control circuit 13 still quits work like this, White LED extinguishes.By the switching tube Q3 of the monochromatic LED control circuit in Fig. 5, light monochromatic LED D2 simultaneously, can realize monochromatic LED D4 and switch to monochromatic LED D2, form color cycle.
When user discharges electronic switch S11, no longer press, all light sources of torch extinguish.
While so having realized the non-illumination of White LED D1, the lighting and the switching of different monochromatic LEDs of monochromatic LED.
