LED luminaires that reduce microbes
New lighting. Fewer bacteria in the air.
EV SUN luminaires replace your existing lighting one-for-one. At the same time they reduce bacteria and fungi in the air around the clock: with ordinary white light, without UV and with people present.

How it works
White light activates the coating. The coating cleans the air.
Visible-light photocatalysis: the luminaire supplies the energy, a copper-based nano-coating turns it into reactive oxygen species, and these destroy microbes in the air circulating around the room.
01 · Light
White, no UV
The luminaire emits in the 450–600 nm range. No UV and no violet glow.
02 · Coating
Copper nano-coating
The optical module carries a factory-applied silica glass layer with copper oxide and titanium dioxide.
03 · Reaction
Reactive oxygen species
Thanks to the nano-coating on the optical module, activated by ordinary white light, reactive oxygen species are formed.
04 · Effect
Fewer microbes
Air circulates around the room. The effect builds up: −34% after 6 h, −92% after 24 h. It works throughout the room, not just near the luminaire.
Coating safety
Cleaning the luminaire does not release nanoparticles into the air.518–654 particles/cm³ against a reference threshold of 20,000.
