Simple LED Torch

This is a simple LED torch.The specialty of this circuit is this circuit helps you to operate your torch for many hours.Here I have used 2W LED.Through this circuit you can light up your torch about one month.Here I have used a common IC 7555.This circuit operates with 6V But if you like to operate this circuit with 9V or 12 V you have to change R3 .If you use 9V use 470 Ohm.If you use 12V use 560 Ohm.

Note

# Build this circuit on a PCB
# Don't use NE555 instead of 7555
# Use alkaline batteries

I don't know whether you have seen leading mobile phone companies use this technology they have applied this method for their screen back light. then tell me are they fools?; November 30, 2013 at 9:10 PM
