LG Innotek announced to have developed the world’s first 100mW (mill watts) UV-C LED.

UV-C LED iemits ultraviolet light with short wavelengths ranging between 200 – 280 nanometers (nm), and is also called Deep UV. It is used in sterilizing and hardening devices with its ability to destroy bacterial DNA and cause chemical reactions with special materials. LG Innotek’s product emits UV in the range of 278nm.

UV-C LED can produce more powerful sterilizing effects with higher light output, but it is very difficult to obtain a stable quality in products with it due to heat. LG Innotek declared to have overcome this technological limit by applying the epitaxial structure and the vertical chip technology that maximize light extraction. The ultraviolet output is raised and the heat is discharged effectively, ensuring stable quality reliability. This one 100mW UV-C LED can emit strong sterilization ultraviolet light for more than 10,000 hours.


As LG Innotek pointed out, the new product can rapidly sterilize flowing water and even air, it can be used in a wide array of household appliances from water purifiers and air purifiers to air conditioning systems for buildings and automobiles as well as water treatment devices. As LG Innotek finally pointed out, conventional UV-C LEDs with a light output level of 1~2mW are mostly used for portable sterilizers or small household appliances. Due to their weak UV-C power, their scope of application is limited.

The UV LED market is expected to more than triple in the year 2020 and continue to expand rapidly.
