Description

Circuit schematic like in Figure 1 above is Circuit Schematic Tiny Emergency Light using Transistor. Eleccirsuits site describe that this is first tiny emergency light of my son. It is very small, use LED display when power outage,use transistor instead relay use AA battery charger.

The transformer T1 will reduce the AC voltage 220V to lower about 6 volts. The AC low voltage will be rectified by diode D1 as half rectifier form. Then DC voltage will flow to resistor R1 and D2 to the battery. The charger current of circuit will set at 55 mA.

And now you can read more you knowledge about Circuit Schematic Tiny Emergency Light using Transistor from the original source article using link [here].
