LG
Innotek today announced that the company has developed the world’s first 100mW
(mill watts) UV-C LED. This development is 2 years ahead of the industry
forecast that predicted its development would be successful by 2020.
UV-C
LED is a product that emits 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. The companies that have led the market have also planned to launch the
100mW UV-C LED by 2020.
LG
Innotek has overcome the 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.
With
this development of the product having a light output of 100mW, LG Innotek has
now become capable of expanding its UV-C LED application field. As the 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.
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.
As
the company has discussed development of a variety of products using UV-C LED
with a number of other global companies and the demand for high-output LEDs
continues to grow, it is expected that the demand for 100mW UV-C LEDs will also
increase rapidly.
LG
Innotek intends to accelerate its securing of the UV LED market leadership. In
particular, the company has confidence in hitting the market with its unrivaled
technology in the UV-C field that can offer excellent sterilization and curing
performance.
The
company’s quality competitiveness has been proven by its launching of
innovative products such as the LED module for sterilizing water purifier
faucet aerator and the UV LED sterilizer for escalator handrails one step ahead
of its rivaling Japanese companies.
A
representative of LG Innotek said, “We will continue to widen the technological
gap with our competitors and introduce innovative products that our customers
desire to stay as the leader of the market.”
