Optronics International’s Purilite Light-Shield is an LED-based decontaminating light designed to improve cleanliness and air quality in and around commercial vehicles.

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 optimal light quality for human vision, approaching 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, adding mass and enabling 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, according to Optronics. 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.
