Optronics’ Purilite Light-Shield LED Lamps Reduces Exposure to Allergens & Pathogens

Optronics International, a leading manufacturer and supplier of LED vehicle lighting, recently unveiled its new LED-based Purilite Light-Shield decontaminating light. The unique LED technology promises to bring a revolutionary level of hygiene to vehicles everywhere, while improving air quality and enhancing occupant safety in the process.

Optronics’ new Purilite Light-Shield LED lighting technology sanitizes vehicle air, while removing hazardous particulate matter from RV, motor coach, public transit, paratransit, shuttle and school bus environments.

Many who frequent RV, motor coach, public transit, paratransit, shuttle and school bus environments are exposed to microscopic airborne pollutants the are so small, they evade the body’s natural defense mechanisms, penetrating deep into respiratory and circulatory systems, and causing damage to lungs, hearts and brains. The U.S. 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 that are found in vehicles that transport or provide living spaces for people. PM2.5 also includes soot that is emitted by diesel engines and APUs.

“Airborne and surface-based mold and bacteria are a concern for RVers, tour groups, commuters and school children who are regularly exposed to biological residue and other contaminants,” said Kyle O’Dell, engineering manager for Optronics International. “Food, waste products, pets, service animals, people and climate all play a hand in allergen and pathogen proliferation in vehicle environments.”

Purilite Light-Shield LED lamps generate a constant stream of negative ions that are created by a proprietary coating applied to their LEDs. The lamp provides decontamination and sanitization functions, while producing optimal light quality for human vision that approaches the color temperature of natural sunlight.

The ionic sanitization occurs through both physical and biological mechanisms. The negative ions bind to lightweight airborne PM2.5 particles. This adds mass and enables natural gravitational forces to remove them from the air by causing them to float safely to the ground.

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.
