Breath, is shown by MCU chip 101 on display 4.
Supply main is connected on controller by single fire mains electricity input end mouthful 701, and passes through controller Shang Danhuo cities
Electricity output port 702 is exported civil power.By carrying out adhesive and disconnected to the magnetic latching relay operating circuit 901 in circuit
Operation is opened, city's electricity output of single fiery civil power output port 702 is realized.
During controller OFF state power taking, magnetic latching relay operating circuit 901 is arranged at off-state by control module 108,
Single fire civil power output port 702 can not directly export high current so that light fixture is lighted, and now full-wave rectifying circuit 902 is gone here and there in civil power
Single fiery mains electricity input end mouthful 701 and single fiery civil power output port 702 are attached in loop.Full-wave rectifying circuit 902 will be handed over
Stream electricity is converted to direct current and is supplied to OFF state single live wire power getting modular converter 107 to carry out power taking operation, and OFF state single live wire power getting turns
Mold changing block 107 stores the electricity of acquirement in electricity memory module 106 by LDO reduction voltage circuits 904.Because OFF state list live wire
When power taking modular converter 107 carries out power taking, faint electric current is only existed in circuit, is not enough to light institute's band light fixture, thus it is complete
Into whole OFF state power taking operation.
During the non-power taking of controller ON state, magnetic latching relay operating circuit 901 is in attracting state by control module 108,
Now full-wave rectifying circuit 902 can not obtain electricity therefore controller is operated in the absence of power taking.Voltage detecting electricity when light fixture is lighted
The moment of road 905 carries out voltage sensing operation to electricity memory module 106.When detecting, the voltage in electricity memory module 106 is low
After overprotection value, corresponding signal is fed back to control module 108 by voltage detecting circuit 905.Control module 108 is receiving electricity
After the signal of low overprotection value, low voltage series offering circuit 903 is opened, while magnetic latching relay operating circuit 901 is entered
Row opening operation.Full-wave rectifying circuit 902 and low voltage series offering circuit after magnetic latching relay operating circuit 901 disconnects
903 are connected in city's electrical circuit simultaneously, because low voltage series offering circuit 903 itself pressure drop is with respect to 220V civil power very littles, therefore
Now light fixture is not in phenomenon that is dimmed or extinguishing.Low voltage series offering circuit 903 is by sealing in itself in city's electrical circuit
The electric difference of generation is sent in ON state single live wire power getting modular converter 105, and ON state single live wire power getting modular converter 105 is by acquirement
Electric energy stores in electricity memory module 106 to realize that ON state power taking is operated through LDO reduction voltage circuits 904.When electricity memory module
Voltage on 106 rises to voltage detecting circuit 905 after protection value and corresponding signal is sent in control module 108, controls mould
Block 108 is after response signal is received by the adhesive of magnetic latching relay operating circuit 901 simultaneously by low voltage series offering circuit 903
Close, single fiery civil power output port is recovered civil power output state.
Controller has weak electric signal and forceful electric power break-make both of which, and row mode is entered by pattern of double controlling selection circuit 908
Selection.Pattern of double controlling selection circuit 908 can be transmitted through artificially manually setting corresponding control model, and by the status information after setting
To control module 108.Control module 108 carries out the switching of corresponding control mode according to received information.
When under weak electric signal mode state, live another way switch is light current mode switch 907, forceful electric power mode switch
906 are not present, and single fire civil power output port 702 is directly connected with the external load 909 such as light fixture.Control module can be with real-time reception
The status information of the lamp control button 6 transmitted to temperature control mainboard 3, while light current mode switch 907 can also be detected whether in real time
Generation switching manipulation.Then it is final to determine magnetic latching relay work after logic judgment of the main control module 108 according to two information
The adhesive of circuit 901 or off-state are to realize that lamp control is operated.
Under forceful electric power break-make mode state, another way switch of system is forceful electric power mode switch 906, light current mode switch 907
It is not present.Single fire civil power output port 702 is connected with forceful electric power mode switch 906, single fire civil power output port 702 and external load
909 be off-state.Forceful electric power mode switch 906 can also first be connected civil power live wire during in-site installation, be connected to the control
Single fiery civil power output port 702 of device, then be connected to through single fiery mains electricity input end mouthful 701 on external load 909.
In forceful electric power break-make mode state, the part of magnetic latching relay operating circuit 901 is carried out by two magnetic latching relays
Lamp control, when forceful electric power mode switch 906 is not acted, the lamp control button 6 that control module 108 is transmitted by temperature control mainboard 3 is believed
Breath carries out corresponding operating to magnetic latching relay operating circuit 901.Magnetic latching relay is worked electric by control module 108 during beginning
A magnetic latching relay in road 901 carries out another road of adhesive and disconnected.If subsequently received lamp control state is changed,
Then now control module 108 disconnects the magnetic latching relay originally disconnected progress the magnetic latching relay of original adhesive simultaneously
Adhesive, therefore realize the on off state switching of light fixture.Do not enter when forceful electric power mode switch 906 carries out corresponding operating and lamp control button 6
Single fire civil power output port 702 is two-way output during row switch motion, wherein all the way magnetic latching relay be attracting state in addition
It is all the way off-state, and this two state will not change.Now only by the operating state of forceful electric power mode switch 906 with reality
The on off state switching of existing light fixture, so as to realize that dual control is operated.
The present invention does not address part and is applied to prior art.
