How to make an Automatic Emergency Light Circuit for simple home uses using led lights.
Today we are going to learn how to make a Automatic Emergency light circuit or Electronic candlefor simple home Power failure situations. Most of the time when unexpectedly power failure occurs suddenly we require a Light dource to see things in the room. For this purpose we are going to make an Efficient Emergency Light which Automatically turns-ON when power failure occurs.
Components Required:
Any Charger suitable for your battery, or 220V to 4.5V / 600mA Transformer D1 = 1N4004D2 = 1N4001R1 = 33Ω/1WattR2 = 470ΩC1 = 470µF/16VT1 = 2SB242 ( This is a pnp type transistor)LED's = Buy 4v led's( 8) Battery = Li-ion 4.5v 4AH or any battery either it is 12v or 6v but you need the good Charger for that battery in my case and also Increase the rating of diodes.
