Battery – The emergency light battery is where power is stored for operation during power outages. Emergency Light Module – The emergency light module provides the light with all the operations required for the supplying power and charging the light fitting.
In addition, the circuit uses an innovative theory to enhance the economical characteristic of the unit. Emergency lights are connected to the electrical supply of the building. Each light has its own circuit. These lights include a battery so that it works like a backup power supply once the building loses its power supply.
To understand the basic principle of battery properly, first, we should have some basic concept of electrolytes and electrons affinity. Actually, when two dissimilar metals are immersed in an electrolyte, there will be a potential difference produced between these metals.
It could be used as an emergency lamp in homes and other places. It could be used in study rooms and workplaces in order to avoid sudden power failures. An automatic Emergency Light Circuit with a battery charger is very helpful as a backup power supply.
An emergency light system is used to turn ON a lamp automatically where a regular AC supply stops working and turns OFF once the main power supply gets back. This light is essential where the power cut occurs frequently, so it can avoid the user from a difficult situation while going through when unexpectedly mains power supply turns off.
The first one is battery charging circuit which acts as an indicator circuit when the power supply is turned OFF. The second circuit is an emergency light circuit that turns on the LEDs according to the light condition. The circuit works on the principle that as long as the power supply is available, the LEDs will not glow.
