Economize on electricity road, adjusts flight control system console operation button indicator lamp brightness.
Background technique
Fly control console operation button indicator light, corresponding working state of system after the operation to show pilot.
Under different flying conditions, brightness requirement is different, such as when working by day, flies control console operation button indicator lamp brightness
510cd/m should be not less than2, and brightness should be 3.4 ± 1.7cd/m when working at night2.It need to be according to work this requires flying control console
External environment brightness conditions when making have operation button indicator lamp brightness regulatory function.
Existing indicator lamp brightness is adjusted in circuit, only adjusts instruction lamp current by potentiometer, and regulating effect is limited, up to not
When multiple indicator lamp brightness being adjusted to indicator lamp brightness adjustable range, when if in addition using, adjustment structure is complicated.
Summary of the invention

When indulging platform work, according to external environment brightness case, position meter knob is powered on by can be manually rotated winged control manipulation deck plate, facilitating spirit
Adjusting control button indicator lamp brightness living.This circuit is simple and easy.
Detailed description of the invention
Fig. 1 is adjusting schematic block circuit diagram of the invention.
Specific embodiment
The present invention is described in further details below.Referring to Fig. 1, flight control system console indicator light supply voltage is adjusted
Circuit is made of a potentiometer, current-limiting resistance, PNP triode and NPN triode and current-limiting resistance；Potentiometer fixing end a is logical
It crosses resistance one and meets 28V, potentiometer fixing end c ground connection, sliding end b connect with two end b of resistance, also connects with the end b of PNP triode
It connects；The end a of resistance two is connect with indicator light low side；The end a of PNP triode is connect with indicator light low side, the end c of PNP triode
It is connect with the end b of NPN triode；The end a of NPN triode is connect with indicator light low side, and the end c of NPN triode is connected to ground；Refer to
Show that lamp is high-end to connect with 28V.
The working principle of the invention is:
A, when potentiometer sliding end b slides into the potentiometer fixing end end c, resistance is minimum between the end potentiometer b, c, partial pressure
Minimum, voltage is less than conducting voltage, PNP triode, NPN between the end b, c of NPN triode between the end b, c of PNP triode
Triode operation is in cut-off region, at this point, being approximately equal to 2 resistance value of 28V/ resistance by the electric current of indicator light, current value is maximum Imax,
Indicator lamp brightness is not less than 510cd/m at this time2, guarantee brightness requirement when indicator lamp brightness meets daytime.
B, when potentiometer sliding end b slides into the potentiometer fixing end end a, resistance is maximum between the end potentiometer b, c, partial pressure
Maximum, voltage is greater than conducting voltage, PNP triode, NPN between the end b, c of NPN triode between the end b, c of PNP triode
Triode operation is approximately equal to 28V/ (2 resistance values of resistance+potentiometer resistance value), electric current by the electric current of indicator light at this time in amplification region
It is worth minimum Imin, indicator lamp brightness is most secretly, to be lower than 3.4 ± 1.7cd/m2, guarantee that indicator light flies control console satisfaction and works at night
Range.
C, when potentiometer sliding end b sliding is between the potentiometer end fixing end a and the end c, at this point, the electricity for passing through indicator light
Stream is approximately equal to 28V/ (2 resistance values of resistance+between potentiometer resistance value b, c resistance value), and current value is between ImaxAnd IBetween min, indicator lamp brightness
Lower than 510cd/m2, it is greater than 3.4 ± 1.7cd/m2, can flexible modulation.
D, as using pipe, it is bigger than PNP triode 3 that NPN triode exports electric current for PNP triode, NPN triode.
One embodiment of the present of invention, used PNP triode and NPN triode are all made of finished parts (triode
3CA3741, triode FH007B).Current-limiting resistance uses power resistor.
