PHOTOLUMINESCENT ESCAPE ROUTE SYSTEMS

New ships, and by October 1997 all ships, must be fitted with low level lighting systems to help evacuation in a fire. This article reviews photoluminescent systems which stay visible even if the power fails and so are very reliable in an emergency. The photoluminescent effect comes from photoluminescent pigments which are incorporated in different host materials, the pigment consists of zinc sulphide crystals. They are able to store visible light energy and set it free with a time delay. It is only after removal of the light source that the crystals release the stored energy slowly, with declining intensity over a period of time.
