nC® Airpurifying Light

nC® Airpurifying Light


nC® Airpurifying Light filters the air through the photocatalytic capacities of titanium dioxide. The most important condition for good and sustainable photocatalysis is light. nC® Airpurifying Light is a light unit already coated with a tailor made titanium-dioxide (TiO2) coating. Therefore, the coating of transparent covers on light armatures of all kinds is a good idea for the air purification and hygienisation of interior spaces, since on the surface of the luminaire there is most of the light energy in the room.


Coated lamps purify the air in a very effective way. The reactive oxygen species generated on the surface of the light covers are capable of effectively removing odors, nicotine, cooking and toilet odors as well as viruses, germs, traces of fungus and bacteria which can be transmitted through the air and come into contact with the light armature cover.

The photocatalytically active coating is fully transparent. Upon radiation with light, the coatings will release oxygen radicals from the ambient air and thus decompose solid and gaseous substrates by oxidation („cold combustion“).


The coating of light armature cover surfaces demands a complex binding system in the coating. A correct processing of the coating on the commonly used PMMA and polycarbonate surfaces has to overcome the very hydrophobic and dense characteristics of these materials. These materials need to be prepared for a permanent coating. For the crosslinking, drying and curing of these special coating systems, various integral process steps including UV and IR to let the TiO2 coating bond into the surfaces are made.


Simple retrofitting of existing lighting systems like grid lights or ceiling armatures in offices, nC offers coated front panels for insertion. These front panels are available in basically all  individual formats.

Test method for air purification performance of photocatalytic materials – “Removal of nitric oxide”, ISO TC 206/SC N.  The test set-up consists of a metal container, in which 1 pavement block is placed, with a UV-transparent glass at the top. Air with a NO-concentration of 1 ppm is blown over the surface with a flow rate of 3 l/min. The height of the free space is 3 mm.  The temperature is approximately 23°C and the relative humidity is 50%.  The nC light intensity is equal to 10 W/m² in the range between 300 and 460 nm.  The maximum is at 365 nm.  The sample has a surface of 100*200 mm².
