Band range and application field of UV LED light source;

UVA [band range 320-400nm]:

It mainly exists in the form of LED lamp beads, and is widely used for UV curing of UV glue, film, ink, varnish, paint and other coatings. Commonly used bands are concentrated at 365nm, 395nm and 405nm.

UVB [band range 275-320nm]: 

It is mostly irradiated by UV tubes, mainly used to promote the growth of plants, with a peak value of about 295nm.

UVC [band range 200-275nm]: 

It is mostly irradiated by UV tubes, mainly used in sterilization and disinfection industry, with an ideal peak value of about 250nm.

Notes for UV-LED 

a. Do not touch the LED, or will affect the normal light-emitting devices

b. Power devices must confirm the positive and negative, reversing polarity may damage the device

c. Strictly operate in accordance with electrical parameters, too high voltage may damage the device

d. UV-LED status should be avoided close observation with the naked eye..

Special precautions must be taken to avoid direct exposure to UV light.

Special precautions must be taken to avoid looking directly at UV light without the use of UV light protective glasses.
