But use the transistor it acts as the switch on off instead may be called a solid state emergency light was.
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.
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.
Nowadays they are mandatory in new commercial and high occupancy residential buildings such as offices.
Hello friends you can make this circuit easily at home just follow my circuit diagram.
And second part consists of relay and rechargeable battery which is used to lighten the leds during power failure.
First part is used to drop down the 220v ac voltage into 8v regulated dc with the help of transformer and bridge rectifier.
The ic has a built in current limiting circuit and a heat sink which helps it to withstand high current as well.
6 emergency lamp using relay.
The tiny emergency light are also special do not uses the relay to on off the lamp.
The 7809 voltage regulator is used to regulate the 12v upto the 9v which is suitable in order to charge our 9v battery.
