Nichia Optisolis LEDs: Revolutionizing the World of Lighting with Full-Spectrum Sunlight Reproduction

NICHIA Optisolis™ Ultra-High CRI LEDs with spectrum closest possible to match natural light

Nichia Optisolis LEDs with the full spectrum of sunlight

Nichia, a global market leader in LED technology, has introduced its latest innovation, the Optisolis™ LED emitters. These groundbreaking LEDs provide a natural light source that achieves the industry's closest match to that of standard illuminants, sunlight, and incandescent artificial light, boasting a Color Rendering Index (CRI) higher than 99. In this article, we will explore the technology behind Optisolis™, its applications, and how it is revolutionizing various industries.


Nichia Optisolis™ Technology: A Closer Look

The extraordinary performance of Optisolis™ LEDs is achieved by using a revolutionary new phosphor technology combined with a special blue LED chip. The spectrum of the blue chip is 420nm, contains virtually no UV emissions, and, when combined with the phosphor technology, enables the exceptional CRI values. The absence of violet or ultraviolet (UV) spectral energy in the emission and a reduced blue light peak are crucial aspects of many lighting applications, such as human-centric lighting, museum and art gallery lighting, and horticulture.

The Optisolis family of LEDs are Ultra-High CRI light sources, as they have maximum scores for all 16 of the color samples that are used in the color rendering index metric. The 5000K Nichia NF2L757G-F1 Optisolis LED can even achieve a Ra of 99 out of 100. Similarly, the scores with the new IES TM-30-15 light quality tests are equally high, with Rf at 98 and Rg at 99.

As the above test shows, the Nichia Optisolis has the highest light quality on the market.

Applications of Nichia Optisolis™ LEDs

1. Human-Centric Lighting

Human-centric lighting is a unique type of lighting that adapts to the human body's internal clock and biorhythm. The Optisolis™ natural light spectrum is a perfect fit due to its ultra-high CRI, while the absence of UV light and reduced blue peak ensure that overall health and sleep patterns are positively influenced. Most human-centric lighting solutions do not have a spectrum that resembles real sunlight, so they end up providing too much or too little blue light. Nichia Optisolis™ LEDs, however, closely match real sunlight, ensuring the correct level of blue light to trigger the desired biological stimulus.

2. Museum and Art Gallery Lighting

For museum and art gallery lighting, Optisolis™ LEDs with their near-maximum CRI and TM-30-15 light quality scores deliver the most faithful color reproduction and the best understanding of an artist's message. The absence of UV light protects precious works of art from light-related damage, while the uniform spectral power distribution enabled by a three-phosphor mix renders art naturally, allowing viewers to fully experience color, texture, and depth.

To implement Nichia Optisolis lighting are museums in Germany and Japan: Zeppelin Museum in Friedrichshafen, the Ludwig Museum in Koblenz and the Picasso Museum in Münster and Otsuka Museum of Art, located in Naruto City, Japan.

 

3. Horticulture


The daylight spectrum of Optisolis™ LEDs promotes optimal plant growth in greenhouses or enclosed spaces. This technology is especially beneficial for plants that require specific wavelengths of light for photosynthesis, as it provides a full spectrum of light that closely resembles sunlight.

4. Color Evaluation

Nichia Optisolis™ LEDs are also ideal for color evaluation applications, such as painting and printing. Their ultra-high CRI ensures that colors are accurately represented under a standard light, allowing for precise color matching and evaluation.

5. Commercial Lighting

In retail and other commercial settings, Optisolis™ LEDs reveal the true colors of merchandise without the harmful UV emissions that can damage printed materials, artworks, textiles, and some fresh produce. The high-quality light spectrum is expressed by both the traditional CRI and the new Color Fidelity Index, with values that indicate the high accuracy of reproducing original colors from 99 representative color indexes.

The Optisolis™ family consists of two series, the NF2W757G-F1 and NF2L757G-F1, both housed in a 3 x 3 x 0.65 mm package. Key features include:

  • CRI: up to 99
  • Typical luminous flux:
    - NF2W757G-F1: 23.0lm at 65mA
    - NF2L757G-F1: 24.1lm at 65mA
  • Max. forward voltage: 3.3 V
  • Radiation angle: 120 °
  • +120°C maximum junction temperature


Nichia's Optisolis™ LED technology has truly revolutionized the world of lighting by providing a full-spectrum light source that closely matches sunlight and incandescent artificial light. With applications ranging from human-centric lighting and museum and art gallery lighting to horticulture and commercial settings, Optisolis™ LEDs offer numerous benefits, including improved health and well-being, color accuracy, and protection of precious items from light-related damage.

As the demand for high-quality lighting solutions continues to grow, Nichia's Optisolis™ LEDs are well-positioned to lead the way in creating more natural, energy-efficient, and visually appealing environments in various sectors. The future of lighting is bright, and Nichia's Optisolis™ technology is at the forefront of this exciting evolution.
