Abstract: An emergency lighting system for an aircraft has photoluminescent strips mounted on the floor rather than a string of electrical lights. This is a better fail-safe since there is no possibility of a failure in power supply.

The photoluminescent strip has two thin layers of photoluminescent material rather on a base layer, rather than being a calendered product. This increases the light output.
