Dual function LED for general illumination and bacteria disinfection

10-02-2021 | NICHIA | Lighting Technologies

Nichia has launched a new dual-function LED that produces white light and high doses of energy geared for inactivation of multiple prevalent bacteria.


Typical bacterias that produce infections are Pseudomonas aeruginosa and Staphylococcus aureus. Furthermore, Escherichia coli (e-coli, O157) which induces food poisoning, continues to plague different parts of the world and continues to be problematic.


The company has produced a new, innovative white LED also capable of inactivating bacteria. It has released the new NF2W585AR-P8, a 4mm x 3.6mm LED.


It has been well-known for many years that UV-C and UV-B wavelengths, ranging from ~200nm–380nm, has been employed for disinfection. However, it has lately been proven that visible light, ranging from ~380nm–420nm, also produces a bacteria disinfection effect.


The new device is an LED solution with a peak pump emission wavelength of ~405nm. Through the company's phosphor and die technology, it can deliver the balance between general white lighting and disinfection bacteria, all out of a single LED.


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