<p>An emergency lighting system for an aircraft has photoluminescent strips (16) 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. A channel extrusion is secured to the floor of the aircraft and a photoluminescent strip (22) is held between the channel and a transparent cover member (20). The photoluminescsent strip has two thin layers of photoluminescent material rather on a base layer, rather than being a calendered product. This increases the light output.</p> |
