As shown in Figure 6, the preferred model of described single-chip microcomputer be STC15W408AS, STC12C5620AD,
PIC16F687、PIC16F1783。
1, after the serial ports of power single-chip machine of the load that user sets or external setting-up device set.Go out
Having relevant initial setting up during factory, client can also carry out free setting.
2, system first passes through current-voltage sampling circuit and carries out current-voltage sampling, and persistently detection one section
Wait upon after time stable after judge whether battery tension reaches requirement voltage, cell plate voltage be in charging or
Discharge condition.As being in charged state, just putting CD1 is high potential, opens charging circuit and enters accumulator
Row charging.As being in discharge condition.Enter discharge procedures.
3, system can carry out delay procedure, and as all of condition can meet requirement, system enters electric discharge journey
Sequence.
4, after entering discharge procedures, the continuous sample battery voltages of monolithic machine side and electric current, LED lamp
Voltage and current.Control FD1 and export pwm pulse signal.Control signal gradually subtracts institute from 100% width
Narrow by after PMOS and coil L.Due to the existence of coil-induced electromotive force, the voltage of LED end from
Zero gradually rises, and LED gradually lights.When the voltage of LED end is equal to, with amp product, the power set,
Single-chip microcomputer stops reducing pulsewidth.At this moment single-chip microcomputer is stored in running parameter at that time in single-chip microcomputer, and continuous defeated
Go out.If after pulsewidth is reduced to zero, the product of the current/voltage detected again without reach set power,
This says that the day running voltage of bright LED is higher than system voltage, needs to enable booster circuit, and at this moment FD1 is defeated
Go out for low level.FD2 is from zero the most broadening pulse.Circuit enters boost mode.Owing to coil L senses
Electromotive force and the existence of electric capacity CF1, the terminal voltage of LED is the faradism that battery tension adds coil L
Kinetic potential.LED terminal voltage can be gradually increased from battery tension.Product until terminal voltage with electric current reaches
Setting power.
5, the problem inside this is, the processing speed sample rate relative voltage of single-chip microcomputer raises there will be and prolongs
Time, ultimately result in output can big word in setting power.Owing to LED is quicker to making voltage and current
Sense.Likely can damage LED lamp.At this moment can not put up with.So when single-chip microcomputer detects electric current,
Just should slow down the process of being increased or decreased.
6, by the discharge curve of LED.The brightness of LED is the most relevant with VF, IF.LED's
C-V characteristic is shown in Fig. 7, wherein VF be the forward voltage drop of LED, IF be forward current.Work as forward voltage
When exceeding threshold value (i.e. conducting voltage, as schemed about 1.7V), IF to VF can be approximately considered and be directly proportional.LED
Lamp is usually and is joined by several to dozens of LED strip or compose in parallel, its VI curve and single curve phase
Seemingly.
7, single-chip microcomputer is often increased or decreased a unit pulse by recording, electric current and increasing voltage condition,
Being calculated by function, duty at that time is in that stage of VI curve.Increase next pulse
Unit will be predicted in advance in that stage of VI curve, and is modified in prediction.Until reaching
To setting power.
8, for the temperature drift in work, owing to LED lamp has negative temperature characterisitic, it is simply that along with
The rising of the operating temperature of LED lamp, its VF voltage can reduce.If the output voltage of controller is protected
Hold constant, it will make the operating current exponentially of LED increase, cause bearing power to exceed rated power.
Damage to light fixture, it is possible to cause the inefficacy of whole light fixture.Controller is bent to VF in real time at work
Line is monitored, and is adjusted the electric current in work, makes it be operated in constant current state, keeps LED
Within tool power is operated in rated power.
