A dual function LED for general illumination and disinfection
NF2W585AR-P8 is a dual function LED that provides both white light and high doses of energy geared for inactivation of various prevalent bacteria. With a 405nm wavelength1 die known to be effective in sterilization, this LED can be used to inactivate bacteria, such as bacteria known to cause food poisoning, while still maintaining the natural white color necessary for traditional lighting applications. NF2W585AR-P8 is particularly suitable for occupied spaces and places where a high level of hygiene is required.
Bacteria Inactivation Test Results with NF2W585AR-P8
|Method||Nichia irradiated bacteria with light and counted the viable bacteria counts after 24 hours.|
|Result||Inactivation rate is 98.9% after 5 hours of irradiation|
|Bacteria species||Pseudomonas aeruginosa2|
(0.127mW/cm2)3 40cm distance
|Lighting Fixture||Lightbar using 9pcs of NF2W585AR-P8|
|Site||Tokushima Prefectural Industrial Technology Center|
These results are dependent on this specific test environment and conditions. Nichia did not check the effectiveness for all bacteria species in real environments.

2 Pseudomonas aeruginosa: This bacteria is seen in wet areas and has a very strong drug resistance. If the human immune system is suppressed, there is possibility that this bacteria would cause a respiratory tract infection, sepsis, etc.. Accordingly, this bacteria has received significant attention in the medical field in terms of nosocomial infection.
3 Wavelength range: 380-420nm.
Situation to Use
In addition to the above, it is also suitable for various applications such as under-shelf lights, interior lights, entrances, elevator halls, and many more.
