Create safe water, air, and environments.
There are two ways to disinfect using UV:
Using deep UV with a short wavelength and using a combination of UV and a photocatalyst.
|Deep UV Disinfection
|UV-A + photocatalyst Disinfection
Greater effect compared
to using UV-A + photocatalyst
Smaller effect compared
to using deep UV
|Lower than normal
Deterioration of the irradiated material
(No direct irradiation)
|Range irradiated with UV||Surface of the photocatalyst
irradiated with UV
|・Air disinfection for air purifiers and air conditioners, etc.
・Water disinfection of plants and tanks, etc.
・Surface disinfection of food factories and hospital equipment, etc.
|・Added disinfection and deodorization
functions to air purifiers and air conditioners, etc.
Why is 280nm the best choice?
Nichia launched its deep UV LEDs at 280nm because of the virucidal power described below as well as the lifetime and reliability of 280nm.
