Delta Electronics is a global leader in electrical power management and cooling solutions. As the Japanese company Ushio’s sole licensee in Taiwan, Delta uses Care222® technology as the best UV bacteriostasis solution to develop various application products that are contactless, residue-free, and more effective than alcohol. The products inactivate both airborne and surface viruses. It has been proved to have a significant bacteriostatic effect on COVID-19 and does not have the danger of traditional 254 nm wavelength UV light, offering a more comprehensive epidemic prevention performance in everyday life.

Ushio is a major manufacturer of special light sources in Japan. In 1987, Ushio came to Taiwan to set up a subsidiary, Ushio Taiwan, to provide professional light-related technology applications to fields such as technology, imaging, and life sciences. Ushio and Columbia University jointly developed the world's first Care222® UV lamp that can disinfect the new coronavirus without harming human health, providing people with a more secure, convenient, and effective method of disinfection.
