As it is used during the power failure it should last long hence generally bright white leds are used in emergency light because they produce more light and consume less power.
Simple emergency light circuit diagram.
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.
The circuit designed with lse is simple and fully automated.
We all know emergency light is used during the power failure to light up the home.
Some emergency light circuit utilizes fluorescent tube but that will consume more.
You can use it in your room if you are facing power failure problems.
This is a versatile circuit and can be used for many purposes.
This particular circuit has been kept so simple for people who has limited access to components or in other words this is an emergency light that you can build with minimum components.
The circuit operation of the device is shown in figure 1.
The circuit is using 12 volt battery.
Leds used in this circuit are low current high brightness white leds hence it will glow longer time with minimum battery power.
Emergency light is an integral part of household electronics nowadays.
The circuit will turn on 1 watt led when there is no light on the surface of the ldr.
Here is a circuit diagram of an emergency lighting made with les.
