6 emergency lamp using relay.
Emergency light circuit using relay.
The 6 high glowing leds are connected in such a way that may save our power.
Simple power efficient and easy to construct led emergency light circuit designed with few easily available components and it is very useful during power outage or instant light needs.
Automatic emergency light circuit using 5v relay.

Leds used in this circuit are low current high brightness white leds hence it will glow longer time with minimum battery power.
And second part consists of relay and rechargeable battery which is used to lighten the leds during power failure.
The ic has a built in current limiting circuit and a heat sink which helps it to withstand high current as well.

Circuit objectives and requirements.
Nowadays they are mandatory in new commercial and high occupancy residential buildings such as offices.
The idea was requested by one of the members of this blog.
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.
The tiny emergency light are also special do not uses the relay to on off the lamp.
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.
Sales bulletin understanding control of emergency lighting circuits 3 ack on relay case 4 normal emergency lights on a ul924 listed dimmer rack case 4 extends the use of the same fixtures for both normal and emergency use because the fixtures are fed.
Working began from ac power is fed into the circuit.
This led emergency light circuit can be divided into two parts.
First part is used to drop down the 220v ac voltage into 8v regulated dc with the help of transformer and bridge rectifier.
Ul924 emergency lighting relays.
Some emergency light circuit utilizes fluorescent tube but that will consume more.
In automatic load control applications when normal power is present the esr relay coil is activated and the emergency panel is.
The 7809 voltage regulator is used to regulate the 12v upto the 9v which is suitable in order to charge our 9v battery.
An automatic emergency light is essentially a backup light that goes off in case of a power outage or an emergency.
