Referring to Fig. 1, opening power switch, power supply electrifying, electric current fills energy, (process list to inductance T1-A by LED light
Piece machine U2 is in floating ground, and high-voltage electricity in 5.1V, has C1 to filter energy storage for power supply by R3 and R4 partial pressure and by RV1 pressure stabilizing, and first
Time controls metal-oxide-semiconductor Q2 and Q1) and power management IC U1 is entered by internal high-voltage MOS DRV foot, gone out by 4 feet, by resistance
R8/R11, which flows back to power cathode, (has voltage comparator voltage at detection CS, electric current is bigger, and voltage is higher, works as electricity at CS pin
Pressure is equal to 0.4V, and high-pressure MOS turns off, and voltage reversal starts to pass through LED light string via SD1 fast recovery diode on T1-A voltage
Circuit electric discharge, this process of discharge off recycle repeatedly, and about 50K times per second, LED light string seems to be exactly the single-chip microcontroller work being always on
Make after tens of μ S, starts to select Q1 conducting, end Q2, only LED light string is bright, while 2 feet of single-chip microcontroller all the way at this time
Be set to input pattern, detection is via R5, the voltage of R6 electric resistance partial pressure, herein voltage should within the scope of single-chip microcontroller high level, and
Filtering out high frequency surging by C3 prevents false triggering, and state is 1 at this time, and when power switch is disconnected, voltage decline is exceedingly fast at R5, quickly
Low level is become by high level at PA2, and single-chip microcontroller is still working, because C1 energy storage exists according to this level change, single-chip microcontroller
It sets Q2 to open, Q1 shutdown, another cluster of lamps, ornamental pearl, which replaces, lights, and realizes replacement colour temperature, and Power switch should be pressed again in 1 second
Conducting, to prevent ruing out of for C1 storage, single-chip microcontroller stops working.After Power is connected again, repeat the above process, it can be again
Realize colour temperature handoff functionality.
Actuation of keys is detected every time, and colour temperature status information can be all stored in power-off by single-chip microcontroller can memory storage body
EEPROM, if it is determined that Power switch just (is greater than 15 seconds) shutdown by desired colour temperature for a long time, until single-chip microcontroller stops work
Make, then single-chip microcontroller can read the colour temperature state of last time memory, and realize regulation color by control MOS switch when powering on again
Temperature.
In view of the same switch control multi-lamp of user, single-chip microcontroller presses patrolling for power switch after work 10 seconds
Collecting becomes restoring default colour temperature, if thinking to change colour temperature again, can continue to operate power switch change colour temperature, single-chip microcontroller is working
When state, at interval of 10S, once button, which will lead to, restores initial colour temperature, continues operation later and carries out by normal discoloration sequence.
Fully powered-off (shutdown 15S) is switched on again restarts the colour temperature of memory last time operation.
