It connects.
When there is electricity, 220 alternating currents are changed into low-voltage AC by 220V alternating currents through Switching Power Supply charging circuit all the way, then
It charges through diode VD6, resistance R5, diode VD7 and fuse F2 to battery E；
The another way of 220V alternating currents：Firewire L is through resistance R11, diode VD10 forward direction rectification decompressions and capacitance C7 and voltage stabilizing
Diode VD9 connections are depressured through resistance R12, reach zero curve N, complete alternating current forward loop, and are embodied as capacitance C7 power supplies,
Making the forward voltage of capacitance C7, triode Q3 ends without output, leads to triode Q2 and triode Q1 higher than triode Q3 base stages
It is also switched off.
During mains failure, battery E pass sequentially through fuse F2, triode Q3, diode VD8, resistance R10, resistance R11,
(equivalent resistance Re is by the normally-closed contact K3 of converter, normally-closed contact K4, inductance L and resistance R3 institute to external circuit equivalent resistance Re
The connection replacement of the near short circuit of composition) and resistance R12 composition triode Q3 forward bias circuit so that triode Q3 is connected,
Due to triode Q3 conducting trigger triode Q2 conductings, triode Q1 is caused to be also switched on, so start inverter circuit carry out starting of oscillation and
The battery DC electricity inversion of low pressure in lamp body is high-frequency and high-voltage alternating current by amplification, lights emergent lamp source, realizes emergency lighting
Conversion；After triode Q1 conductings, triode Q2 self-lockings, constant conduction are realized through resistance R7, and then maintain emergency lighting work
State；
Obviously, if having a power failure, the normally-closed contact K3 of relay T2, the normally-closed contact K4 of relay T1, inductance L in converter
Unicom is unable to some node in fuse F1, the triode Q1 base stages of lamp trigger circuit cannot then complete access, then should
Anxious lamp cannot be converted to emergency lighting, moreover during power failure, if normally-closed contact K3, normally-closed contact K4, inductance L and fuse F1 are
It connects, lamp light switch K1 is in the conversion that any state does not all interfere with emergency lighting.
Although the circuit design is simple, safety coefficient is very high.The circuit will not all be sent out always because of converter failure
Raw power supply high voltage short circuit blows out phenomenon because its internal unicom take it is similar control plant-grid connection with door mode,
It employs or the mode of door carrys out the cut-out of control circuit, further normally opened contact K2, normally-closed contact K3 are also all relay T2 lines
Circle one group of opposite contact and form interlocking.When converter inside element has indulged damage, the state short circuit of formation low current also has molten
Disconnected device F1 is protected, malfunction indicator lamp VD5 is reminded, all too many levels common guarantees circuit safety performance.
By the intelligent converter and lamp body internal trigger conversion circuit collective effect, need the power supply of three lines that could manage script
It controls the emergency light usually illuminated and is converted into two wires power supply, no matter switch which kind of on off state K1 is in, various functions are unaffected,
So that all emergency lights are (without the emergency light that management and control usually illuminates as indicated indicator light and emergency lighting lamp without installation
Converter) complete simple two wires power supply can be realized in building.
Three line of intelligent fire emergency lighting mains supply line provided by the invention becomes two line converters, by converter by three
Line power supply is converted into two wires power supply so that usually emergency light with illumination functions realizes two wires power supply, maintenance and it is easy to maintain,
The material used is greatlyd save, and makes emergency light line attachment more simple and convenient, while causes building emergency lighting master
Supply line simplifies, and has the characteristics that reliability is high, safe, convenient for the long-range and centralized Control to emergency lighting.
Above content is only the design example and explanation to the present invention, affiliated those skilled in the art
