Nichia’s Vitasolis enables breakthrough human centric lighting

Tokushima, Japan – May 17, 2019 – Nichia Corporation will unveil a state-of-the-art LED spectrum technology, called Vitasolis at LIGHTFAIR International (USA, May 21 -23). This technology, which will be first incorporated in Nichia’s market leading 757 platform, will help control human circadian rhythm via a unique spectrum meant to stimulate activity. While Nichia previously presented the technology at The Phosphor Global Summit 2019 as well as the 2019 Department of Energy SSL R&D Workshop, Vitasolis will be on display at LIGHTFAIR International within Nichia’s Booth #1119.

Until now, the primary goal of LED lighting has justifiably been energy savings. However, recently the focus in many lighting applications has shifted towards improving the quality of light as well.

With over 50 years of phosphor experience and research, Nichia Corporation is strongly engaged in contributing to society through lighting, including improving the quality of light ("AKARI”). The innovative Vitasolis technology is another example of Nichia’s contribution, now through human centric lighting.

Recent research has further revealed the relationship between light and human behavior. Humans not only recognize brightness and color of light, but human circadian rhythm can be affected by different wavelengths, especially the cyan region. For example, lighting can have an influence on activity levels throughout the day, including waking up in the morning, being active during the day, and encouraging sleep at night. While Vitasolis provides a very natural white color, part of its spectrum contains a larger amount of energy in the cyan region, which helps control the human circadian rhythm. The unique spectral distribution of Vitasolis cleanly illuminates objects while maintaining a high luminous efficacy.

The benefits of the Vitasolis technology provide a great opportunity for adoption in offices, schools, hospitals, and other locations that can benefit from improving circadian rhythm. Nichia envisions manufacturers combining Vitasolis into IoT systems and providing suitable lighting based on the time of day and desired environment. Nichia is confident that Vitasolis will truly enable the ideal human centric lighting experience.
