Energy.
When switch K1 is off, V1 lamps do not work, and now 220 voltage L ends are after C1 electric capacity and C2 capacitance decompressions
12V voltages are exported through diode D1-D4 rectifications, C3 capacitor filterings, VD1 voltage-stabiliser tube voltage stabilizings to power to whole circuit.As now used
When hand touches P points, Q1 triodes produce small-signal voltage through R1 resistance in base stage, make Q1 triode ONs, Q1 triodes are led
After logical, make Q2 triode ONs, colelctor electrode exports high level to electric capacity C4 quick charges, while makes after R5, R7 electric resistance partial pressure
Q3 triode ONs, emitter stage output high level, Q4 triode ONs are made after R9, R10 electric resistance partial pressure, make LED1, LED2 white
Color luminous tube lights.Now, after hand leaves P points, Q1 triodes and Q2 triodes by, and now C4 electric capacity to be fully charged,
C4 electric capacity is held on Q3 triodes by R5 resistance, and Q4 triodes are held on, and LED1, LED2 keep luminous.When certain
After time, after the point stored by C4 electric capacity is discharged, Q3 transistor bases because of no-voltage and by, Q4 triodes by, LED1,
LED2 luminous tubes open LED night lamp because no-voltage is without luminous, so as to reach to touch, and are closed automatically after one end time that is delayed
LED night lamp.After P points are touched with hand, LED night lamp such as needs turn on lights V1 during bright, after now being connected because of K1,
For the step-down rectifying circuit that C2 electric capacity and D1-D4 diodes are formed equivalent to being short-circuited, C3 electric capacity both ends will be defeated without 12V voltages
Go out, now on C4 electric capacity charged pressure by the positive pole by D5 diodes to C3 electric capacity, then by R6 resistance to discharge,
After reaching K1 switch connections, LED night lamp can be closed to the function of LED night lamp within the time for light delay in advance.
Such as now, then by K1 disconnect, after closing V1 lamps, LED night lamp is still in closed mode.LED1 and LED2 hairs need to be such as lighted again
Light pipe, only it need to touch a P point with hand again.
