What is Photoluminescent?
BackPhotoluminescence
is the discharge of an electromagnetic radiation (Photons) of a
material after being submitted to a luminous excitation.
The
photoluminescent substances, when subject to ultraviolet radiation
transmit visible light through a phenomenon of atomic excitation, that
being excited by ultraviolet radiation gather energy that they release
through time under the shape of a visible light until all the atoms go
back to their fundamental state.
The
excitation of the photoluminescent security system is then a
pre-requirement for the emission of luminescence. On the other hand, the
light intensity emitted by the photoluminescent surface depends on the
quantity of energy that the product was able to absorb (depending on the
time of the UV radiation and energy, the wavelength and the frequency
of the radiation) i.e. it depends on the time of exposure to the
surrounding light and to the type of light used in its stimulation.

Photoluminescent safety signs are signs that have a resin covering with photoluminescent substances in its composition.
The photoluminescent sign has the purpose of effectively transmitting the message for which it was manufactured, i.e. to show alarm equipment, fire equipment, safety equipment, etc.). It also shows escape routes (exits, doors, etc.), the dangers, the obligations or the prohibitions, guaranteeing total understanding, even in blackout situations.
The adaptation of Everlux products to the market's needs and to the national and international normative requirements is assured by a process of continuous investment, in innovation and development of new products and new technological solutions.
