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 emergency exits 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 corridor lamp fee includes two parts, one is the maintenance fee and the other is the electricity fee. However, in practice, the charging standards of corridor lights are different and there is no uniform standard, which makes the contradiction between the owners and the property management department sharp.

There are still many corridor lights that still use light bulbs and old-fashioned switches to stay on all night. If the corridor lights are changed to LED lighting, an acousto-optic switch is used. The power consumption of this solid-state lighting lamp with LED as light source is only 65,438+0/8 of that of ordinary incandescent lamp, but its service life is 65,438+00 times.
