Maximizing UV emission with vertical chip technology
Improved output compared to existing products, applicable to medium to large appliances

LG Innotek announced that it has developed a UV-C LED with an ultraviolet output of 70 milliwatts (mW). This performance surpasses existing 45mW products.

UV (ultraviolet rays)-C LEDs, which can sterilize even flowing water or air, emit ultraviolet rays 70 times stronger than those used for toothbrush sterilization and can be used for various purposes such as water purification, filtration, and curing.

Conventional UV-C LEDs have weak ultraviolet output, making them difficult to apply to medium and large home appliances, so they were mainly used to sterilize small items such as toothbrushes. The power level is 1mW for toothbrush sterilization and 2mW for humidifier water tanks.

UV-C LEDs emit ultraviolet light with a short wavelength of 200 to 280 nanometers (nm). Also known as Deep UV, it sterilizes by destroying the DNA of bacteria. The wavelength of LG Innotek's 70mW UV-C LED is 280nm.

The 70mW UV-C LED maximizes the emission of sterilizing ultraviolet rays using vertical chip technology. In addition, although its size is 6 millimeters (mm) by 6 millimeters, the same as the 2mW class, its output is 35 times stronger.

Unlike mercury UV lamps, the 70mW UV-C LED is an eco-friendly product that does not generate harmful heavy metals and has excellent durability.

LG Innotek has a product lineup optimized for each application, including 280nm UV-C LEDs, 365nm, 385nm, 395nm, and 405nm UV-A LEDs for general industrial use, and 305nm UV-B LEDs for bio and medical use.
