In the world of lighting sources, where there is often a tendency to prioritize luminous flux and efficiency, Nichia has strived to convey that CRI is just as important as luminous flux and luminous efficiency. Nichia, which has been involved with “light” for more than half a century since the fluorescent lamp era, hopes that this part of its philosophy has been understood...

Until today since the discovery of ultraviolet germicidal effectiveness in 1901, primarily low-pressure mercury lamps have been used for disinfection with ultraviolet. Low-pressure mercury lamps contain mercury and therefore generate concerns regarding environmental pollution. LEDs are expected to be an environmentally friendly alternative technology, similar to the LED replacement of fluorescent lamps. However, although improving year over year at a great rate, the current efficiency of UV LEDs is still less than low-pressure mercury lamps. Thus, the RoHS Directive exe...
