Optronics debuted its LED-based Purilite Light-Shield decontaminating and sanitizing lamps that generate a constant stream of negative ions, created by a proprietary coating applied to their LEDs. 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; 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.
Optronics’ Purilite Light-Shield also produces optimal light quality for human vision, approaching the color temperature of natural sunlight.
