TULSA, Okla. — Optronics International introduces its new LED-based Purilite Light-Shield decontaminating light to help improve air quality.
RVers are exposed to microscopic airborne pollutants so small that they evade the body’s natural defense mechanisms, penetrating deep into respiratory and circulatory systems, and causing damage to lungs, hearts and brains, the press release explained.
The United States Environmental Protection Agency (EPA), has developed ambient air quality trends for particle pollution, also called particulate matter (PM).
PM 2.5 describes fine inhalable solid particles and liquid droplets, with diameters that are generally 2.5 micrometers and smaller.
These particles include many types of mold and bacteria found in vehicles transporting food, and also includes soot emitted by diesel engines.
“Airborne and surface-based mold and bacteria are also a concern for people who are exposed to biological residue and other contaminants,” said Brett Johnson, president and CEO of Optronics International.
Purilite Light-Shield LED lamps generate a constant stream of negative ions, created by a proprietary coating applied to their LEDs.
The lamp provides decontamination and sanitization functions, while producing light for human vision, approaching the color temperature of natural sunlight.
The ionic sanitization occurs through physical and biological mechanisms. The negative ions bind to lightweight airborne PM2.5 particles, adding mass and enabling natural gravitational forces to remove them from the air by causing them to float safely to the ground, the release explained.
The negative ions also combine with positive molecules in mold spores and bacterial proteins, destroying them and causing them to decompose.
Once terminated, what’s left of the pathogens also fall inertly to the ground. With viability removed, the biological remnants are rendered essentially sterile, reducing exposure risks even if they are disturbed and become airborne again, the release noted.
“When the lights are on, they are doing their job, it’s deceptively simple,” Johnson said. “An RVer can flip on these lights, go grab a bite and when they return, the interior environment will be significantly cleaner. If they prefer, drivers can remain in the cab while the lights are working, it’s perfectly safe just to leave them on.”
Preliminary tests in a controlled environment show a 77 percent reduction in PM2.5 and a 65 percent reduction in Escherichia coli (E. coli) in just one hour, according to the company.
Testing also compared Purilite Light-Shield with standard LEDs as well as no light source.
“Until today, surface cleaning procedures and bacteria-resistant surface treatments were the only methods available,” Johnson said. “Optronics’ Purilite Light-Shield is the first technology to transcend simple surface-oriented decontamination methods and move toward cleansing the entire interior environment of a vehicle, including the air.”
