Embodiment
Below in conjunction with specific embodiment the utility model technical scheme is further specified:
As shown in Figure 1; The embodiment of the utility model is: through making up a kind of LED knob film control device; Comprise the knob resistance 8 of dividing potential drop, the processor unit 1 that carries out control and treatment, the pwm unit 2 that carries out pulse width modulation, the driver element 3 of driving LED lamp, power supply 4; Said voltage outputs to processor unit 1 through said knob resistance 8 rotation dividing potential drops, makes the corresponding pulse width modulating signal of driver element 3 outputs control said LED lamp 4 thereby said processor unit 1 outputs signal to said pwm unit 2 output pulse width modulation signal values.
As shown in Figure 1; The practical implementation process of the utility model is: concrete technical scheme is: through the knob electric resistance partial pressure; Said voltage outputs to processor unit 1 through said knob resistance 8 rotation dividing potential drops; Processor unit makes the knob analog signal be converted into digital signal through AD conversion (analog-to-digital conversion) again, and said processor unit outputs signal to said pwm unit 2, the PWM value of the corresponding duty ratio of said then pwm unit 2 outputs; Thereby make drive circuit 3 also export corresponding PWM, so just can export different brightness different colours.
As shown in Figure 2; The preferred implementation of the utility model is: said control device also comprises the RCU 6 that the LED lamp is carried out remote control control; Said RCU 6 connects said processor unit 1; Also comprise and instruct the button 7 of input, the connection of the speed key in the button 7, brightness key, mode key, on & off switch, Pause key is to have judged whether that through timing scan button presses, thereby carries out control corresponding.
Concrete control procedure is following: said control device also comprises the regulon 9 of regulating impulse bandwidth modulation signals, and said regulon connects said pwm unit.Said regulon also comprises the preset module 91 that presets LED lamp pattern; Said preset module 91 connects said driver element 3; Said regulon 9 is when carrying out the adjusting of LED display mode; Select through said RCU control model after pressing the model selection button, the LED lamp pattern of selecting preset module 91 to preset shows.
Said regulon 9 comprises the brightness regulation module 92 of regulating the brightness of LED lamp; Said brightness regulation module 92 realizes the bright dark of brightness through changing the PWM value; Regulate PWM and be exactly through regulating the time scale of PWM drive circuit conducting and shutoff in the cycle, the LED lamp is operated under the state that does not break off and close, always owing to human eye has visual persistence effect to light on physiology; As long as the time of opening and closing is lower than 0.02s; Human eye can't see LED has flicker, and the time ratio of an interior conducting of PWM cycle is long more, and the LED lamp is just bright more.Said regulon 9 comprises the speed regulation module 93 of regulating LED lamp flash speed; Said speed regulation module 93 was controlled through the retention time that main processing controller unit 1 comes control Driver Circuit to open and close; Because minimum hold time surpasses 0.1s; Human eye can be seen LED lamp flicker, through regulating the speed that this retention time of opening and closing regulates flicker.Said regulon 9 comprises the time-out module 94 of suspending the LED lamp; Pause function is applicable to LED lamp dynamic change pattern; Comprise gradually varying type of flicker changing pattern and light and shade; The dynamic change pattern is to adopt different modes to come the state of opening and closing of controlling and driving part and the time scale of opening and closing to realize by processor unit 1 according to different changing patteries, and processor unit 1 is always upgrading open and closed that drive and the time scale of opening and closing continuously automatically, when starting pause function; Suspending module 94 makes processor unit 1 can stop to upgrade state of a control and remaining on current states; After closing pause function, processor unit 1 can be a starting point with the current states, restarts to upgrade automatically continuously the control state of a control.Said regulon 9 comprises the switch module 95 of switch LED lamp; Switch module 95 is through the operating state of processor unit 1 controlling and driving department circuit; Control through setting the time scale that the PWM cycle opens and close, the value that PWM is set at off state is 0, promptly at a PWM in the cycle; Only relevant state, the state of not opening is realized shutdown.
