Photoluminescence involves using a substance designed to absorb emitted light energy so it can be radiated or glow in complete darkness. Multiple forms of this process are possible with the simplest being resonant radiation. Resonant methods absorb a specific wavelength and then emit the same wavelength. Energy transitions are minimal, making this type of radiation quite fast. Photoluminescent materials operate through internal transitions that occur before the photons are emitted. Fluorescence is the most common effect, and it is the fastest energy transition. Energy lost during this process causes lower amounts of energy to be released during radiation.
Photoluminescent light may be released over a specific amount of time or consist of a highly advanced state for glow in the dark materials. These materials are beginning to play a big role in safety applications such as egress signs. Many international and local guidelines regulate the usage of safety identification items in buildings. Building owners are being encouraged to install these products for improved safety identification.
Self Luminous Safety Signs: Why Are They the Better Building Egress Choice?
As a building owner, any item that reduces costs and increases your environmental reputation is beneficial. Self luminous safety signs are not only dependable, but can save money when added to your buildings egress identification plan. These products are becoming a main focus of owners, structure architects, and design engineers. Light Emitting Diode, or LED signs, was one of the first steps toward a more eco-friendly solution. These reduced power consumption from the maximum of forty watts to five watts or less.
While this is quite an improvement, these lighting products have their down sides. The products are not as safe in all emergency conditions, have continual efficiency issues, and do not supply the sustainability of advanced products being offered for your building today.
Tritium signs became an alternative option to incandescent safety identifiers. Their glow stems from hydrogen radioactively decay into helium. While these products do not use electricity to provide lighting, they are still harder to dispose of and pose the danger of explosion during a fire.
Self luminous safety signs are an energy free and safe alternative for your building. They are completely nontoxic, do not include radioactive compounds, and use stored energy to light up an exit or egress path. Energy stored by these materials is released as a greenish or yellow glow that appears any time traditional lighting cannot be supplied. This lighting effect may be compared to technology included in toys or other “glow in the dark” products; however, safety products radiate brighter for a longer time.
Photoluminescent products are easy to implement within your building. They require no electrical connection process, making installation possible in a matter of minutes. You can implement them to ensure occupant egress safety. GloBrite products eliminate signing energy costs, are not harmful to the environment, and are recyclable. By installing them in your structures, you can be certain occupants will be capable of exiting regardless of the emergency conditions. They meet all standard building code requirements and can provide astounding cost savings.
