NICHIA Dual Function LED 06.10.2021

NICHIA Reveals Dual Function LED for General Illumination and Bacteria Disinfection.

With the continued surge of COVID-19 and the global impact across the globe, there is a heightened awareness to cleanliness in all aspects of life. While this certainly applies to viruses, it also applies to various types of bacteria present in our daily living environments.

Typical bacteria examples that cause infections are Pseudomonas aeruginosa and Staphylococcus aureus. Additionally, Escherichia coli (e-coli, O157) which causes food poisoning, continues to plague various parts of the world and remains problematic. Throughout its 65-year history, Nichia has always worked hard to contribute to society through development of innovative products, including LEDs. To assist with the global efforts in reducing these harmful bacteria, Nichia has developed a new, innovative white LED also capable of inactivating bacteria. Nichia has released the new NF2W585AR-P8, a 4.0mm x 3.6mm LED, a staple of Nichia’s General Lighting portfolio. It has been well-known for years that UV-C and UV-B wavelengths, ranging from ~200nm–380nm, has been used for disinfection. However, it has recently been proven that visible light, ranging from ~380nm–420nm, also has a bacteria disinfection effect.


Nichia envisions this LED will be widely used for environmental hygiene maintenance in food factories, kitchens, hospitals, public facilities, and similar applications.
