Nichia expands its Optisolis™ technology into a COB series

Tokushima, Japan – January 25, 2019- Nichia Corporation is proud to expand its award winning Optisolis™ natural light source technology with a portfolio of COB packages.

To further improve the overall quality of light as "AKARI”, Nichia has developed Optisolis™. As Nichia continues to lead the industry with innovative products, Optisolis™, which launched in February 2018 with a Nichia Mid Power LED series, provides a natural light source with a spectrum that achieves the industry’s closest match to that of the standard illuminant, including both the sun and incandescent. Optisolis™, which was first presented to the industry at The Phosphor Global Summit in 2016, is optimized for the general lighting market and is accomplished through Nichia’s own blue chip and phosphor technology.

Nichia has now launched the Optisolis™ technology in a COB series that features high luminous flux and a narrow emission area. The COB footprint is ideal for products that require high light density, including spot lights, down lights, track lights and more. Nichia’s Optisolis™ COB further raises the standard for color quality.

Manufacturers can utilize Nichia’s Optisolis™ technology and trust in a spectrum where all colors are reproduced to that 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.

Optisolis™ target applications include Museums, Art Galleries and Hospitals, where a natural light source is preferred to most accurately represent an object, but UV radiation and light sources can be detrimental. Additional applications could include Color Evaluation（e.g. painting, printing), Commercial Lighting (e.g. retail, etc.) or anywhere a natural light source is desired.
