Fire Exit Signs
Fire exit signs are devices in public buildings that show the way out. The pictogram variety, with or without the text supplement, is used for most fire exit signs around the world and this sign can also be illuminated, since smoke or failure of electrical lighting may reduce visibility in a fire, usually by one of:
- Photoluminescent phosphorescence, where light is absorbed from the surroundings and slowly re-emitted
- Electric light, with a local rechargeable power source
- Electric light, with the building's emergency lighting circuits providing backup power from a UPS and/or generator in case normal power is lost
