Human centric lighting in LED diode with Nichia’s Vitasolis

Japan’s Nichia Corporation has introduced a state-of-the-art LED spectrum technology called Vitasolis that will help control human circadian rhythm via a unique spectrum meant to stimulate activity.

Nichia had previously presented the technology at The Phosphor Global Summit 2019. It is now available in Nichia products, initially the company’s market-leading 757 diode platform.

Until now, the primary goal of LED lighting has justifiably been energy saving.  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.  The Vitasolis technology is another example of Nichia’s contribution.

Recent research has further revealed the relationship between light and human behaviour. Humans not only recognise brightness and colour 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 colour, 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.
