Violet-pumped Nichia LED offers quality light and germicidal benefits

Maury Wright at LEDs Magazine reports ed on what the company calls a strong 405-nm pump in the violet region and Nichia phosphor technology that can deliver a uniform spectral power distribution (SPD) over the bulk of the human visual range. The product is intended primarily to defend against pathogens such as staph and E. coli. The new Nichia LED is designed for use in what we initially had called continuous-disinfection applications, meaning that the deactivation spectrum would operate 24 hours a day as opposed to, say, using ultraviolet (UV) radiation in the UV-C band (100–280 nm) to instantaneously…
