The construction principle of emergency lights is as follows:

The emergency light is composed of lighting fixtures, batteries, chargers, and controllers. The interior of a lamp is usually equipped with LED bulbs or fluorescent tubes, which are powered by a battery. When powered by an external power source, the battery charges and provides power to the lamp in the event of a power outage. The controller is used to control the switch and charging circuit of lamps, and has functions such as timing, light control, and alarm. Emergency lights can also be equipped with sensors to achieve automated control.

When the mains power is normal, the charging circuit of the emergency light will receive electricity from an external power source to charge the battery. When the mains power is cut off, the controller will control the battery to output electrical energy, supply power to the lamps, and then achieve emergency lighting. At the same time, the controller can notify the user in a timely manner through the alarm function, prompting them to take corresponding measures.

The construction of emergency lights is simple and easy to understand, but it is important to note that they should be installed and operated correctly according to the instructions during use to ensure their normal operation and extend their service life.
