What is the green light in the corridor?

The emergency exit indicator light is a kind of indicator light for people to reach a safe area, so ensuring the emergency exit is an important measure to prevent group deaths and injuries. Safety evacuation signs should be set at the top of the emergency exit or on the wall below the ground 1m at the evacuation walkway and its corner, and the spacing between signs on the walkway should not be more than 20m.

Fire emergency lighting and safety evacuation indicator lamps shall be equipped with protective covers made of glass and other incombustible materials.

Corridor lamp prospect:

Corridor lighting belongs to public facilities. In principle, the owner and the property jointly undertake the installation, maintenance and management. The cost of corridor lights includes two parts, one is maintenance and the other is electricity. However, in practice, there are different fees for corridor lights, and there is no unified standard, which makes the contradiction between owners and property management departments sharp.

There are still many corridor lights that are still lit all night with light bulbs and old-fashioned switches. If the corridor lights are changed to LED lighting, an acousto-optic switch is used. This solid-state lighting lamp with LED as light source consumes only 1/8 of that of ordinary incandescent lamps, but its life span is 10 times.
