A square-shaped luminaire measuring approximately 2 feet by 2 feet, utilizing light-emitting diodes as its source of illumination, designed to fit into standard suspended ceiling grids. This type of lighting fixture incorporates a battery that provides power in the event of a mains electricity failure, ensuring continued illumination during emergencies. For example, in a commercial office building, these fixtures can replace traditional fluorescent troffers, providing energy-efficient and reliable lighting.
The integration of emergency power capabilities offers enhanced safety and compliance with building codes. Historically, emergency lighting involved separate systems and dedicated circuits. This integrated solution simplifies installation and maintenance while offering significant advantages, including energy efficiency due to the LED technology and reduced risk of accidents or panic during power outages. The consistent illumination provided by these units helps maintain visibility for safe egress from a building.
