Here i am going to present you a simple Emergency Light circuit diagram using 2 white Leds. Leds are convenient, cheap, cool and having long life. In this circuit we are using 2 Leds (white is prefered) to increase the brightness. The heart of this circuit consists of IC HEF 4093. The circuit is powered by a 9V battery.

Ne555   is one of the most commonly used timer IC. It is a monolithic timing circuit that can produce accurate and highly stable time delays or oscillations. Like general purpose OP AMPs, it is very much reliable, easy to use and cheaper in cost. It has a variety of applications including monostable and astable multivibrators, dc-dc converters, digital logic probes, waveform generators, analog frequency meters, tachometers, temperature measurement and voltage regulators. The timer basically operates on one of the two modes either as a monostable or as an astable multivibrator. Read More.....
