Photoluminescence really is a complex term that represents a quite straightforward phenomenon - an item's ability to create light without having the help of commercial energy options including electricity and batteries. In technological terms, this phenomenon happens whenever an item absorbs photons by ambient lighting and then re-emits the actual photons inside darkened surroundings, making a lighting effect which runs from ambient to vibrant based on the object's absorption potential. Using a quantum mechanics viewpoint, the object goes from a high energy state to a low energy state, re-emitting the photons until finally it loses its light.

These kinds of objects are usually named "self-sustaining" since they make their very own energy, an ideal example of which can be found in the most commercially widely used of just about all such products - photoluminescent exit signs.

Companies who are dedicated to being environmentally friendly and conserving capital have popularized these types of exit signs throughout the management and business market. The safety signs perform a function in the U.S. General Services Administration's plan for environmentally friendly design ideas, which attempts to decrease non-renewable electrical power usage. The signs are also a part of Victoria, Australia's Department of Sustainability and Environment's program to follow green urban construction. In addition to preserving non-renewable energy, the actual signs are bright, recyclable, non-toxic and, in contrast to classic safety signs, non-radioactive.

The importance of the egress signs to companies that are going green is noticeable, but even for businesses that haven't gone green, switching from incandescent safety signs to other signs which are much more energy conscience minimizes operating costs. Incandescent egress signs run 24 hours a day, 365 days a year. Add in the price of replacing light bulbs, back-up batteries in addition to fixing defective wires and, for a big company, the price difference could possibly amount to thousands of dollars every year. Besides being maintenance free, the exit signs have a common life time of 25 years.

For lowering power usage as well as servicing expenses, tritium, small fluorescent and LED safety signs are likewise cost effective alternatives to incandescent evacuation signs, however the last two are not maintenance free and all three have a shorter life time compared to photoluminescent signs. The ordinary lifetime for tritium evacuation signs is 10-20 years, while the life span of LED and compact fluorescent signs is around eleven years and roughly six years, respectively. Photoluminescent signs are actually also easy to move if egress routes change, whereas LED and compact fluorescent signs will need re-wiring. Compared to the competition, the exit signs are the best long-term ecological and monetary investment.

Based on a popular photoluminescent safety sign company, the ten-year running cost for one of its exit signs, which includes labor and installation, is $111.00. Relatively, the ten-year running expense of a tritium exit sign is determined at $190.00, when the ten-year operating cost for individual LED, compact fluorescent and incandescent egress signs soars to $370.00, $894.00 and $1,465.00, respectively.

Nearly all companies that offer photoluminescent egress signs sell other self-sustaining signs as well, including fire hose and fire extinguisher signs, stairwell signs, direction arrows and photoluminescent marking tape for distinguishing pathways in dim surroundings.
