9。
Capacitor 2 is electrically connected with control unit 1, provides temporary source for control unit 1；When switch 3 is closed, temporarily
Power supply is supplied to control unit 1, so that control unit 1 is run a period of time, the size of capacitor 2 determines 1 energy of control unit
The length of runing time under power blackout situation.
Switch 3 is electrically connected with step-down rectifier module 4, control circuit on-off；Switch 3 opens or closes state, makes circuit
Generate switching signal.The switch 3 can several in parallel LED light 9, i.e. a switch 3 can control multiple LED light 9, makes LED light 9
Generate richer illumination effect.
Step-down rectifier module 4 is electrically connected with switch 3, is provided power supply for control unit 1 and drive module 7, is exchanged 220V
Power voltage step down rectification output is stablized.
Switching signal module 5, for receiving the switching signal of switch 3 and switching signal being sent to control unit 1；It is adjacent
The time interval of two switching signals is less than or equal to 2.5 seconds.LED light 9 is realized in being repeatedly opened or closing by switch 3
Either on or off and control illumination effect variation, it is easy to operate, reduce production cost.Multiple LED light 9 can be attempted by one simultaneously
On switch 3, realize that synchronously control enhances output effect.
Memory module 6 can enter last time when turning on the switch 3 next time for storing the luminance of current LED light 9
The luminance of storage will switch to the luminance of last time without turning on the switch 3 every time.
Drive module 7 drives LED light 9 to work according to the signal of control unit 1；
LED light 9 is electrically connected with drive module 7, can produce different colours or variation.LED light 9 includes feux rouges lamp bead, green light
Lamp bead and blue light lamp bead.
