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
