Nichia Corporation has developed an Ultra-High Colour Rendering white LED with a spectrum that demonstrates the closest match to that of the standard illuminant. Named Optisolis, which was first presented to the industry at The Phosphor Global Summit in 2016, it is optimised for the general lighting market. This one-of-its-kind technological breakthrough is achieved using Nichia’s own blue chip and phosphor technology.
Optisolis targets applications include Museum and Art Gallery Lighting, where the highest CRI is preferred, but UV radiation and light sources can be detrimental. Additional applications could include Colour Evaluation (e.g. painting, printing), Commercial Lighting (e.g. retail, etc.) or anywhere Ultra High CRI is desired.
According to company, manufacturers can utilise Optisolis and trust in a spectrum where all colours are reproduced to the colour seen under a standard light. Most importantly, since UV emission is essentially non-existent in the spectrum, the degradation of irradiated materials can be reduced dramatically compared to that of other light sources containing UV emission, including other market available LEDs.
