SIGNS
Photoluminescent Step Edge Products
Our Emergency and Egress signs are high brightness, glow-in-the-dark products with the resilience to be installed in any environment. That includes indoor/outdoor as well as installation onto floors and walls.
The process of photoluminescence allows certain substances to emit light after they have absorbed various kinds of energy. The process involves:
1. The absorption of energy - normally light. This causes the electrons of the atoms of the absorbing material to become
excited and jump from the inner orbits of the atoms to the outer orbits.
2. When the electrons fall back to their original state, photons of light are emitted.
Visibility
When primed with the appropriate levels of light, our systems are visible to patrons entering a darkened stadium from brightly lit external areas at 10 meters (30ft)- after 140 minutes of black-out in the stadium.
The crystals continue to glow until exhausting the energy they have absorbed, but they can be recharged repeatedly by re-exposure to light - maintaining their luminescence for the life of the stadium.
The pigment is non-radioactive, non-toxic, and responds to both solar and artificial light sources. A hard, long-lasting finish protects the surface of the disks and nosings.
