Number resistance R4, preceding pull down resistor R5 and anti-interference capacitor C2；Above-mentioned electronic component is sequentially formed by following sequence electrically to be connected
It connects：AC input, rectifier diode D5, power resistor R2, power resistor R3, filter capacitor C3, voltage-stabiliser tube diode D6 are to calmly
When U1 working power anode foot, timing U1 cathode foot ground connection；AC input, signal resistance R4, preceding pull down resistor
R5, anti-interference capacitor C2 are to timing UI input terminals；The output end of timing UI pull down resistor R7 to metal-oxide-semiconductor Q2 after current-limiting resistance R6
Grid, metal-oxide-semiconductor Q2 source electrode ground connection, the drain electrode of metal-oxide-semiconductor Q2 meets constant current resistance RS1 and completes total power output, when timing UI is defeated
Go out low level metal-oxide-semiconductor Q2 cut-off cut-outs RS1 to complete to reduce power output.
In the timing Variable power module 10, the constant current resistance RS1 is connected to the main circuit constant current letter at IC integrated controls end
Number sampling end.The size that the sampling end of main circuit constant current signal changes constant current signal voltage can change the big of constant-current power
It is small；When being powered on since the output pin of timing UI is high level, the constant current signal part at 2 ends is led in metal-oxide-semiconductor Q2 conductings
Cross RSI and Q2 reduces the sampling voltage of constant current signal with being diverted to so that constant-current power increase is total power output, when timing
ICUI exports low level metal-oxide-semiconductor Q2 cut-off cut-outs RS1 and completes to reduce power output afterwards.
The Q2 parameters are NPN, and R2R3 power resistors are 33K, D5 rectifier diode 1N4007, D6 zener diodes ginseng
Number is 6.2V, filter capacitor C3 is 100uf；Signal resistance R4 is 1M, anti-interference capacitor C2 is 10nf；Timing IC U1 are that 6-7 is small

A number part is through RS to ground, and another part then flows into ground by RS1 to metal-oxide-semiconductor 2, at this time namely 1 end of master chip to be through
Crossing RS and RS1 parallel connections makes master chip full power operation.The UI output low level metal-oxide-semiconductors Q2 cut-offs when timing arrival is 6 small
RS1 ends, and 1 end electric signal of master chip only has RS to ground, and if RS and RS1 values are essentially identical, power at this time is total power
Half.Only wait until the repeatable above work acted that is powered again after having a power failure.
Another application method of the utility model is：Constant current resistance RS1 is not connect into 1 end of main circuit but is connected to
2 ends of main circuit, since 2 ends are the samplings of main circuit constant current signal, constant current can be changed by changing the size of constant current signal voltage
The size of power.When being powered on since the output pin of UI is that the Q2 conductings of high level metal-oxide-semiconductor are a part of by the constant current signal at 2 ends
The sampling voltage of constant current signal is reduced by RSI and Q2 with being diverted to so that constant-current power increase is total power output, when fixed
When the time reach the sampling voltages of 6 hours UI output low level metal-oxide-semiconductor Q2 cut-off RS1 cut-off constant current signals and rise so that constant current
Electric current reduces to achieve the purpose that reduction power, the size of resistance RS1 will match with R1, does not connect RSI adjustment R1's temporarily
Resistance value is allowed to for half-power, access RS1 again at this time, adjusts the resistance value of RS1 and keeps the Matching and modification of its total power at this moment RSI and R1 complete
Finish.
It can be seen that after using the utility model, a street lamp may be implemented full power operation time after midnight before midnight be from
Dynamic drop half-power work, substantial saved electric consumption, while also increasing the service life of lamps and lanterns.This patent is in intrinsic base
It is very little that 6 small metal-oxide-semiconductors of diode 1 of resistance 2 and 1 timing chip institute Zeng Chengben are merely added on plinth.Therefore it uses
This patent can make product save electric energy automatically and increase service life.
