Previously, the available radiant flux within a given space was limited, and due to the large scale of industrial applications, mercury lamps have traditionally been the primary choice for such processes. However, compared to mercury lamps\u2014which take time to reach full power\u2014the ability of LEDs to switch on and off instantly significantly reduces standby power consumption.<\/p>\n<section style=\"box-sizing: border-box\">On 21 September, Nichia also launched the high-radiant flux NCSU434B UVC-LED, operating at a wavelength of 280 nm. It boasts the industry\u2019s highest power conversion efficiency for a 3.5 mm \u00d7 3.5 mm LED, delivering a typical radiant flux of 62 mW at a typical input power of 350 mA\/5.7 V. Furthermore, in high-density installations, the radiant flux per unit area is approximately three times that of conventional products. Mass production has now commenced, with the product intended for use against various bacteria and viruses, particularly in industrial water and air applications.<\/section>\n<section style=\"box-sizing: border-box\">\u00a0<\/section>\n<section style=\"box-sizing: border-box\">UVC-LED is currently one of the most popular methods of sterilisation; it is expected to revolutionise sterilisation and disinfection efficacy and may lead to safer conditions for eliminating pathogens. This is widely recognised within the industry and represents a significant shift in the future of UV disinfection, moving away from the current use of mercury lamps towards UV-LED disinfection.<\/section>\n<section style=\"box-sizing: border-box\">\u00a0<\/section>\n<section style=\"box-sizing: border-box\">The latest high-output UVC-LED, the NC4U334BR, has been launched to meet, to a certain extent, market demand for industrial water treatment and air purification. Importantly, this compact and efficient LED delivers high radiant flux and high power. Compared with previous technologies, this solution enables greater system miniaturisation and offers highly stable, long-life performance.\u00a0<\/section>\n<section style=\"box-sizing: border-box\">\u00a0<\/section>\n<section style=\"box-sizing: border-box\">Nichia pledges to continue focusing on the development of deep-ultraviolet LEDs with higher performance and reliability, and to contribute to the realisation of a mercury-free and carbon-free society through energy efficiency.<\/section>\n<\/section>\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Nichia\u2019s New 280nm High-Output UVC-LED NC4U334BR, October 2021 On 6 October, Nichia announced the launch of its high-output UVC-LED, the NC4U334BR, further demonstrating its commitment to UVC-LED technology.
