Emergency Light Circuit Using Relay

This 6th simple led relay changeover emergency light circuit using a battery back up which gets charged during mains presence and changes over to led battery mode as soon as mains fails.

Emergency light circuit using relay.

Nowadays they are mandatory in new commercial and high occupancy residential buildings such as offices. Our ul924 emergency lighting relays can be used for automatic load control or bypass shunt applications to turn on emergency lighting in the event of the loss of normal utility power. And second part consists of relay and rechargeable battery which is used to lighten the leds during power failure. Working began from ac power is fed into the circuit.

The 6 high glowing leds are connected in such a way that may save our power. 12v emergency light circuit using d313. Leds used in this circuit are low current high brightness white leds hence it will glow longer time with minimum battery power. This led emergency light circuit can be divided into two parts.
