Or a type of lamp that can continue to illuminate without interruption, and is widely used in public places and places where lighting cannot be interrupted.

But existing emergency lights are often used in factories, mines, institutions, schools, buildings and tunnels. The emergency lighting system used is relatively independent of conventional lighting lamps and control circuits. This kind of emergency lighting setting method increases the cost of lighting fixtures and increases the complexity of controlling lighting circuits.
