The visibility of emergency exit signs using phosphorescent materials

The optical characteristcs and visibility of emergence esit signs made with phosphorescent materials have been studied and compared with conventional signs. The phosphorescence of the materials meets standards as defineds by JIS, and achieved a level of brightness recognizable by the human eye. The visibility in the dard of the signs using the phosphorescent materials was shown to be higher than that of currently employed materials. It was confirmed that phosphorescent materials show excellent promise to improve the visibility of emergency exit signs.
