In particular, the firm is introducing Japan’s first UV LED sterilizer for escalator handrails, emitting 275-278nm-wavelength light of to destroy germ DNA. The product can sterilize germs for the whole duration of escalator operation and is easy to install and manage, says the firm. Since the product was launched in Korea and China last July, it has been installed in about 30 locations, including shopping malls, hospitals and airports.
LG Innotek is also showcasing UV-C LED modules for sterilization that can be installed in home appliances including water purifiers, air purifiers, etc. The firm will also show a cork sterilization module, installed in LG Electronics’ ‘PuriCare Slim Updown’ direct water purifier. Unlike mercury UV lamps, the module does not generate harmful heavy metals and, due to its durability, it does not easily break.
In addition, LG Innotek is exhibiting 365, 385, 395, 405 and 415nm-wavelength UV-A LEDs that are used in curing equipment in manufacturing facilities. Curing hardens coating agents, adhesives etc or dries inks. The firm will show a 305nm UV-B LED, which is gaining attention for biotechnology and medical applications.
