Battery E charges.The b poles of V1 are connected to voltage-regulator diode D2, and resistance R1 is both the base electrode bias resistance of V1, are again the current limliting electricity of D2
Resistance, its charging current changes with the voltage of battery, and voltage is lower, and charging current is bigger, otherwise smaller.In charged state,
V2 saturation conductions, V3 is ended due to the effect of D1, R6, and V4 is also switched off, so light fixture H does not work.
When power supply VCC has a power failure for some reason, diode D5 positive pole no-voltages, due to being in saturation conduction state before V2 power-off,
So V3 switchs to conducting by cut-off at once, the b electrode potentials of V4 are raised, and V4 is lighted also with conducting, light fixture H.After V4 conductings, V4's
C extremely low potentials, due to R8 be connected across the b poles of the c poles of V4 and V3 and between, the b electrode potentials of V3 decline, and maintain the conducting shape of V3
