Simple Emergency Light Circuit Diagram

The circuit will turn on 1 watt led when there is no light on the surface of the ldr.

Simple emergency light circuit diagram.

A very simple and useful circuit of a emergency lamp. The circuit is using 12 volt battery. Power outages are a recurring thing but in some cases power outages are not allowed such as ongoing surgery. 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.

We all know emergency light is used during the power failure to light up the home. In addition to circuit diagram he has shared photographs of the prototype he made in national emergency light and a pcb design. You can use it in your room if you are facing power failure problems. Leds used in this circuit are low current high brightness white leds hence it will glow longer time with minimum battery power.

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. The circuit designed with lse is simple and fully automated. 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. This is a versatile circuit and can be used for many purposes.

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