When (1) initial, electric light 302 goes out: the PIO port default output high level of BLE single mode chip 101, and when the PIO port was output as high level, controllable silicon drove optocoupler and is in off state, and then bidirectional triode thyristor turn-offs, and the loop of electric light is in off state.
(2) electric light 302 brightens by going out: the user can be by the BLE Bluetooth function on the operating handset 301, setting up BLE with the bluetooth controllable power switch 303 in the electric light 302 is connected, and to select the brightness degree A(A of electric light 302 by corresponding application software on the operating handset be a grade in 2 to 8 grades), BLE single mode chip 101, when the Bluetooth control with class letter A that receives the outside is opened signal, detect the zero point of alternating current and start timer by zero cross detection circuit 102, the timing of timer is corresponding with the class letter A that Bluetooth control is opened signal, when timer reaches timing, to silicon controlled control circuit 103 output low levels, so that controllable silicon drives optocoupler 203 conductings, drive bidirectional triode thyristor 204 and enter conducting state, and then make silicon controlled control circuit 103 conductings, during bidirectional triode thyristor 204 conducting, electric light 302 is equivalent to path, and electric light 302 is bright.Bidirectional triode thyristor has the characteristics of zero-crossing switching in alternating current circuit, therefore when arrived the next zero point of alternating current, bidirectional triode thyristor turn-offed, but because the current output of PIO port of BLE single mode chip is low level, therefore bidirectional triode thyristor closes the again conducting of having no progeny, so repeatedly.Because the frequency of alternating current is 50Hz, therefore the turn-on and turn-off of this frequency can not be by the naked eyes perception, and therefore, electric light 302 just is in bright state always.
(3) to be transferred to another grade B(B by grade A be a grade in 2 to 8 grades in the brightness of electric light 302, different from A): the user is adjusted into B by controlling on the mobile phone corresponding application software with the brightness degree of electric light 302, BLE single mode chip 101, when the Bluetooth control with class letter B that receives the outside is opened signal, detect the next zero point of alternating current and start timer by zero cross detection circuit 102, the timing of timer is corresponding with the class letter B that Bluetooth control is opened signal, when timer reaches timing, to silicon controlled control circuit 103 output low levels, so that controllable silicon drives optocoupler 203 conductings, drive bidirectional triode thyristor and enter conducting state, because the change of timing, the size of thyristor operating angle just changes thereupon, and then the size of the equivalent current of the electric light 302 of flowing through also changes along with the change of thyristor operating angle size, and the brightness of electric light just becomes grade B by grade A.
(4) electric light 302 is gone out by bright change: corresponding application software sends a Bluetooth control pass signal to the user on the mobile phone by controlling, BLE single mode chip 101, when the Bluetooth control that receives the outside is closed signal, export high level by PIO port on the BLE single mode chip 101 to silicon controlled control circuit 103, so that driving optocoupler 203, turn-offs controllable silicon, and then silicon controlled control circuit 103 is turn-offed, electric light 302 is gone out by bright change.
