Simple Emergency Light Circuit Diagram

The circuit operation of the device is shown in figure 1.

Simple emergency light circuit diagram.

Some emergency light circuit utilizes fluorescent tube but that will consume more. 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. 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. We all know emergency light is used during the power failure to light up the home.

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. Power outages are a recurring thing but in some cases power outages are not allowed such as ongoing surgery. Leds used in this circuit are low current high brightness white leds hence it will glow longer time with minimum battery power.

In addition to circuit diagram he has shared photographs of the prototype he made in national emergency light and a pcb design. 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. You can use it in your room if you are facing power failure problems. A very simple and useful circuit of a emergency lamp.

The circuit is using 12 volt battery.
