How Do Jalite Photoluminescent Materials Work?
Photoluminescence is a special kind of phosphorescence. The energy needed to activate it is supplied by common light sources such as daylight, tungsten filament, and fluorescent lights.
Under sudden power loss situations, the material is conspicuous at some distance, providing an effective, bright contrast for text and graphical symbols and ensuring that safety messages are quickly recognized.
This assists people to orientate themselves so that they can react effectively and evacuate efficiently.
Jalite photoluminescent materials contain purpose-designed inorganic phosphor compounds that are energized in seconds.
This high-energy source in converted into a lower energy source of light. The lower energy light source is yellow-green, the color most readily perceived by the human eye and as specified by safety signs standards.
Jalite photoluminescent materials are non-radioactive, non-toxic and self-extinguishing.
Can Photoluminescence Replace Traditional Emergency Lighting?
The short answer is NO. As long as the electrical emergency lights work they provide a light environment similar enough to "normal," the safest condition to evacuate a facility.
However, while electrical emergency lights often work, their limitations are well documented.
Jalite products accommodate for electrical lighting shortcomings in more ways than one. They are typically low-located and are FAIL-SAFE.
In a smoky environment, traditional high-located emergency lights can be obscured, while Jalite products installed close to the floor would continue to be visible. Water from fire hoses or damage from a fire can prevent backup electrical systems from operating, whereas no part of an escape route marked with Jalite products will fail under these extreme circumstances. |
