Photoluminescence describes the ability of an object to emit light without the being fuelled by commercial energy sources, for example, batteries and electricity. This phenomenon can actually be explained scientifically. It happens whenever particular substances absorb photons from a light source and then later on emits the photons in darker areas. It creates lighting effect which ranges in brightness depending on the ability of the object to absorb the photons. The object loses its energy gradually until all of the light goes out. This how the photoluminescent exit signs NYC uses works.
Such materials are often referred as self-sustaining. This is so because they seem to produce light energy on their own. This property has made them popular in decreasing energy costs. Their usage in exit signs production attests to this. Without their usage, energy costs levied on NYC government would be significantly higher.
Industries committed to green revolution and cost-effectiveness also use these items in the corporate world. Agencies within the federal government charged with making plans for minimizing energy consumption, especially non-renewable energy, favor their use. Apart from reducing consumption of non-renewable energy, the exit signs are also bright, non-radioactive. They also do not emit toxic fumes or contaminate the environment. The items also can be recycled.
Their significance in sustaining the green revolution is very obvious. Top on the list is its ability to cut down cost to the authorities and companies that use them. The cost of maintaining incandescent exit signs is too high. First, they burn for the whole day throughout the year. In addition, there is also the cost making repairs to faulty wiring and replacing burnt out bulbs and batteries. In large organizations such as the county governments or even large corporations, the cost of maintenance throughout the year is significantly high. The best option for them is a maintenance-free one that can be used for up to twenty five years.
LED, compact florescent and tritium exit signs are the alternative to photoluminescent and incandescent ones. These are also less costly, but the LED and compact florescent types need maintenance services. When compared to the photoluminescent type all the three have a shorter lifespan. The tritium type lasts about 10 to 20 years while the LED and the compact florescent type have 11 and 6 years respectively.
The other benefit it that they are very easy to move around when there is a change in egress paths. LED type and compact florescent require rewiring in such events. The photoluminescent type is the best as a long-term investment (environmentally and monetarily) when compared to the rest.
One popular manufacturer puts the ten-year cost of using this item as one hundred and eleven dollars including installation cost for every sign. The over the same period of time tritium costs one hundred and ninety, while that of LED, compact florescent are 370 and 894 dollars respectively. Incandescent is the costliest at 1465 dollars.
With the above mentioned figures, it becomes crystal clear that the photoluminescent exit signs NYC use has huge benefits. They also have a high safety profile. This is a great way of going environmentally friendly.
