Nichia Launching Significantly Improved UV-C LED

Nichia, the world’s largest LED manufacturer and inventor of the high-brightness blue and white LED, will start mass production in December of another new high radiant flux UV-C LED to help target the inactivation and sterilization of various bacteria and viruses, specifically industrial water and air applications.

With its small 3.5mm x 3.5mm size, the NCSU434C has industry-leading radiant flux (110mW) and wall-plug efficiency (5.4%) when compared to a UV-C LED of the same size, an ~80% flux improvement over its predecessor, thus enabling smaller and more dense designs. Nichia expects the NCSU434C to be implemented in various large flow water and air disinfection equipment for inactivation of various viruses, including the new coronavirus and sterilization of bacteria. These levels of performance improvements further justify the immediate replacement of environmentally harmful mercury lamps with LED systems.

Nichia promises to continue to develop not only deep-ultraviolet LEDs but also higher-power ultraviolet LEDs with improved performance to help solve various social issues and to assist in achieving a mercury-free and carbon free society through energy conservation.

Contact a Nichia representative for samples of discrete LEDs or samples mounted on boards to expedite design efforts.
