PHOTOLUMINESCENT

Safety System with Photoluminescent Materials  

 

Advantages

 

     Good Illumination of areas to be safeguarded

 

Good visibility of markings, diagrams, signs, telephones, fire extinguisher, rescue equipment

 

     Good psychological effect inspires confidence and discourages panic

 

Perfect recognition of corners, turnings, taps, switches

 

      Economical,  even small rooms or dead ends can be equipped with Photoluminescent products at minimal cost

 

The layers of Photoluminescent materials are very thin, so they may be applied everywhere without decreasing the space of the passage. Wear-resistant paints can even be applied to floors

 

Photoluminescent coatings are very robust and due to their thinness not in danger of mechanical damage. At the same time, they are resistant to mechanical strain. Even strong mechanical abrasion cannot lead to failure; at worst, the light intensity decreases, if part of the coating is knocked off

 

Photoluminescent products are usually applied on large areas. Therefore, partial soiling does not impair the effectiveness. Their efficiency is only slightly affected by single objects or persons in front of the coated areas.

 

Photoluminescent products are usually applied in the form of a guidance line, on the floor or the lower part of the wall, so that this can be followed even in strong smoke by crawling

 

The functioning of the Photoluminescent materials is guaranteed from 50 to 100 C provided the materials are given sufficient light before blackout, total or partial failures are impossible

 

Part of the lighting system providing energy to the materials may fail, but does not lead to failure of the materials; it only decreases the light intensity in an emergency.

 

     All possible defects of the lighting system will be immediately obvious, such as breakdown of light installation, soiling of the Photoluminescent coatings or mechanical damage.

 

Photoluminescent systems function for more hours than electric systems, providing an aid to fire and rescue workers. The glow of the materials will not dazzle their dark-adapted eyes

 

No additional expenses, this system needs no maintenance other than cleaning if and when necessary.

 

No checks of functioning need be made visual inspections are sufficient.

 

 

Disadvantages:

 

Lower brightness than lamps

 

Decrease of light intensify as stored light is emitted. However, this decrease is compensated to a great degree by the adaptation of the eye to the decreasing light

 

      It is necessary to illuminate the evacuation routes at least from time to time

 

      The light intensity depends on the brilliance of the light prior to the blackout, and on the source of light.
