Out Of This World Led Torch Circuit Diagram

A common problem with small torches is the short life span both of the batteries and the bulb.

Led torch circuit diagram. The led torch in fig. Learn more how to build it. This prevents the battery from over discharge which extends the battery performance and life.

Working of simple led torch light circuit the supply voltage is given to the circuit is 5v dc. The circuit has good battery life. Led based torches are quite extensively used these days.

In the circuit the resistor r1 and capacitor c1 are arranged with two not gate to make an oscillator circuit. Here is a led torch circuit which uses 3 7v lithium polymer rechargeable battery. A simple led torch circuit that would light up 3 white leds from a 6 volt supply and would make your battery last forever is described here.

The working led torch circuit as figure 1 is circuit diagram we also the principle of the switching supply. Try conrad electronic for what appears to be a stronger white led order code 15 37 45 11. Although the torchs light output is modest it.

1 consumes just 24 mw giving it more than 80 times longer service from 4 aa alkaline batteries that is up to one month s continuous service. The remaining 4 not gates connected in parallel to make a buffer and double the input voltage. This is a simple led torch circuit based on ic max660 from maxim semiconductors.

In the simple oscillator generator we use transistor cs9013 and coil l1 l2 as main parts. The led torch is based on a 7555 timer running in astable mode do not use an ordinary 555. As a added feature this circuit also comes with battery discharge protection.
