LG Innotek, a global component-specialist company, has introduced the world's strongest UV-C LED, a diode which emits super-strong ultraviolet light capable of killing off germs and bacteria.

Ultraviolet (UV) LEDs are widely used for sanitation from toothbrush sterilizers, mid-sized refrigerators and humidifiers to air purifiers. It is also used to sterilize stagnant water. UV LEDs kill germs by destroying DNA. Previously, the strongest UV LED was produced by Japan's Nikkiso and its output was 45mW (milliwatts).

"With our unique technology, we have maximized the output of UV rays," said an LG Innotek official. "By using the UV-C LED, it would take much less time to sterilize germ-infested water and air."

The new UV-C LED's output is 70mW, about 55 percent stronger than the Japanese competitor. It is strong enough to be applied inside large industrial machines and home appliances. The LED unit is very small, 6 x 6 millimeters in a square shape. It's the same size as a 2mW UV LED and 35 times stronger.

With the previous 2mW UV LED, it took about 25 minutes to sterilize five liters of water. LG's is powerful enough to sterilize running water and LG Innotek suggested its technology would be applied more widely.

According to a technology market research company, Yole Development, the world's UV LED market is expected to increase from 130 million US dollars in 2015 to 270 million dollars this year.
