Photoluminescent Signs for Corridors and Emergency Exits
These signs are designed for locations where normal lighting may fail and people still need to follow safety information—for example, corridors, stairs and emergency-exit routes.
Also known as photoluminescent or glow-in-the-dark signs, they absorb ambient light and remain visible by releasing stored light when the surroundings become dark.
Glow Duration of Photoluminescent Signs
The Persian page states a maximum glow duration of approximately six hours. Brightness gradually decreases during this period. Actual performance depends on prior illumination and material characteristics.
UV Printing Process
Persian Safety uses photoluminescent material with UV-printed graphics for its emergency-exit signs. The page describes this printing method as offering greater durability than conventional alternatives.
Acrylic Backing Material
The backing is made from 3 mm acrylic sheet (Plexiglass). The source describes the material as high-quality, smooth and flat, without visible warping.
Precision Laser Cutting
The acrylic backing is laser-cut, with rounded corners and smooth edges to avoid sharp or hazardous edges.
