According to the industry’s sources, Ultra Violet-C LED (UV-C) devices which are made by Taiwan-based makers will be featured in at least four to five models of home appliances which are to be launched in the second half of 2019 by international vendors.
The Ultra Violet-C LED devices target maternity, kitchenware, and other segments like baby-care, the sources told.
According to Minamata Convention on the production of mercury, its exports & imports of related goods containing mercury will be banned by the beginning of 2020, paving the way for the new UV-C LED to replace the old mercury lamps for disinfection purposes.
Lite-On Technology has revealed that a high-power UV-C LED device, with a single 270 to 280-nanometer chip emitting 130 megawatts Ultra-Violet light at 350mA current, the sources specified, adding the device can 99.99 percent disinfect drinking water flowing at 2 liters per minute.
For UV-C LED chips, two to five percent of luminous efficiency is employed in disinfection, High Power Lighting indicated, adding depending on the area, as well as, the distance of disinfection & the level of disinfection, an appliance is prepared with 1-6 UV-C LED chips. Its main aim is to ship one million UV-C LED chips every month in 2020.
Lextar Electronics, Opto Tech, Epistar, & Everlight Electronics are all set to offer UV-C LED chips or packaged devices. According to them, the popularity of UV-C LED for disinfection is dependent on the chip production cost reductions & consumer awareness, the sources told.
There is a huge potential demand for using the new Ultra Violet-C LED for disinfection apps. AT present, Japan-based Dowa Electronics Materials, Nichia, Nitride Semiconductors & South Korea-based Seoul Viosys and LG Innotek are leaders on a global level in the developing of UV-C LED disinfection applications, the sources revealed.
