What is automatic LED emergency light?
What is automatic LED emergency light?
An Automatic LED Emergency Light circuit is designed to turn ON when there is no adequate lighting or if the power supply is cut-off. Earlier fluorescent lights were used to build such circuits. But the use of LEDs has proven to provide adequate lighting for a longer period before draining the battery.
How do you make an automatic LED emergency light?
Components for Automatic LED Emergency Light Circuit

What are the advantages of automatic LED emergency light?
The automatic emergency lights built with LEDs are proven to provide adequate lighting for a longer period of time. The automatic emergency lights will provide you with a light-sensing feature. This will give you an automatic supply of electricity in case of emergency situations.
How do you use an automatic emergency light?
Procedure to implement the Automatic Emergency Light circuit Keep the switch at the On position and Give the AC main supply to the circuit, you will be able to see the battery is charging and the LEDs are not glowing. Now turn off the AC main supply and you will be able to see the LEDs are glowing.
How do emergency LED bulbs work?
The Emergency Bulb provides the same soft white light as a 60-Watt LED light bulb, 800 LED Lumens. The LED Emergency Bulb works like an energy-saving bulb during regular use and switches to emergency light during a power outage, running on a lithium-ion battery.
How does an emergency light works?
Emergency lighting is wired to the building’s power supply for continuous charging of internal batteries to provide back up power for the lighting. This ensures that lights remain alight during a power outage allowing occupants to easily locate the exits should they need to evacuate the building.
What is inverter LED bulb?
An inverter LED bulb is essentially an emergency LED bulb. The technology used in these bulbs enables them to automatically turn on the LED light during a power cut and automatically charge the internal battery when AC mains is available. Basically, inverter LED bulb is a two-in-one bulb.
How does an emergency light circuit work?
Is there an automatic LED emergency light circuit?
The automatic emergency LED light circuit can be designed in two parts. 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.
How does LDR work in led emergency circuit?
When power supply is turned OFF, the circuit senses the day light and according to the light it turns on the LED’s. If the light is present even though power fails the circuit turns OFF the LEDs. Here LDR (Light Dependent Resistor) is used to sense the light.
How long does an emergency light circuit last?
This is the simple and cost effective automatic LED Emergency Light Circuit with light sensing. This system charges from main supply and gets activated when main supply is turned OFF. This emergency lamp will work for more than 8 hours (depending the battery capacity and the power consumed by the LEDs).
Why are LED lights good for emergency lights?
Use of LED lights helps you in less energy consumption as well as provides comparatively bigger life to the light devices. In this project, we will be discussing the Automatic Emergency light circuit project along with the necessary steps involved in the process to design the circuit.
