Why Emergency Lights Are Must?

by:UFO      2020-07-22

Most business enterprise complexes, student hostels, theaters, and high occupancy residential complexes generally have an emergency light inside it. Even a few of the older buildings, which originally could not have them, are installing them now to maintain the security regulations. Besides, aircrafts and ships and army vehicles, or any vehicle or location from where an emergency exit might be needed, have it installed.

An emergency light is the people's protector while power goes away without alert. Portable torch lights have always used as it to help people manipulate their way on unlit roads, or to help them discover their way inside a home where power has failed. However, the term emergency light is at the present applied to a light that lights up instantly when power fails. Many houses and buildings have them, and in some places the law insists that larger complexes are well protected against power outrages by carefully installed emergency lights.

The essential components and parts of an emergency light are one or more light bulbs and a energy generator system. Older models of it were incandescent lighting. But after the arrival of LED lights, many building owners prefer to use LED lights because it is likely to be a lifetime investment. As it will probably be used only rarely, and LED lights will usually have a life span of greater than 50,000 hours, the issue of replacing the lights are not likely to occur.

The light intensity of an emergency light needs to be decided by the area it has to cover. High lumen floodlights are used in many larger buildings because they offer a larger area to be illuminated. When the power fails, the sensor in the emergency light is activated via a relay mechanism. Some types of it get switched off by itself by the same system when power returns, however others needs to be manually switched off. If it is not reset, these models will stay lighted even after the normal power supply is back to regular.

The word egress indicates coming or going out, and an emergency light setting is likewise known as egress lighting or emergency egress lighting system. In many buildings this are installed close to the exit sign to make it easy for people to leave in case of sudden power failure. In some instances the exit sign itself will be the emergency light.

Apart from buildings, it is used in aircrafts, ships, army tanks, and amphibious vehicles that can be driven both on land and water. It is necessary in mines, theaters, and at all temporarily set up fairgrounds or carnival venues. Basically, an emergency light is useful and necessary at every place where emergency egress or evacuation of people could become necessary. Wherever it is applied, an emergency light requires a self-contained power source.

Lots of research has been conducted in the field of emergency lighting systems. An Emergency Light used nowadays has a switch that can be manually operated or is automatically initialized by the built-in sensor. Experiments are being made in building lighting systems, which can utilize fresh, or salt-water activation, or chemical lighting, or bio-luminescent lighting, depending upon the conditions in which they are used.
