The Concept of Human Centric Lighting

Human Centric Lighting (HCL) is a design philosophy that prioritizes the impact of light on human physiology, psychology, and overall well-being. With the advent of tunable white LED technology, it has become possible to replicate the natural light cycle indoors, creating environments that promote comfort and efficiency. Typically, HCL systems use a combination of warm (2700K) and cool white (6500K) LEDs to mimic the changing color temperature of daylight, which can range from the warm hues of dawn to the bright, cool light of midday.

Importance of 480nm Light and Dynasolis™ Mechanism

Morning light, rich in 480nm wavelengths, plays a crucial role in regulating the body’s internal clock by stimulating serotonin production—a hormone that enhances mood and energy levels. Higher serotonin levels in the morning lead to increased melatonin production in the evening, promoting better sleep and overall health.

Conventional tunable white systems often fall short in this regard, as they rely on cool white LEDs that lack sufficient 480nm spectrum, resulting in suboptimal serotonin stimulation and, consequently, lower physical and mental activation throughout the day. Dynasolis™ addresses this shortcoming by replacing the standard 6500K LEDs with azure LEDs, which are optimized to deliver the necessary 480nm light. This enhancement maximizes melanopic illuminance, boosting alertness in the morning and fostering relaxation followed by improved sleep in the evening, by gradually transitioning to warmer light tones.

With this innovative approach, Nichia’s Dynasolis™ represents a significant advancement in human-centric lighting, offering a unique solution that combines spectrum and color tuning to regulate circadian rhythms. By incorporating energizing azure light and calming warm white hues, Dynasolis™ enhances physical and mental well-being, making it an ideal choice for many applications, from offices and homes to healthcare facilities and schools. As more people become aware of the health benefits of proper lighting, Dynasolis™ stands out as a versatile and effective solution for creating optimal lighting environments.

Study on the Cognitive and Psychological Effects of Dynasolis™ Lighting Solution by Fraunhofer Institute for Building Physics

To validate the benefits of Dynasolis™, Nichia commissioned the Fraunhofer Institute for Building Physics (IBP) to conduct a comprehensive study analyzing its cognitive and psychological effects.

Study Design and Methodology

The Fraunhofer IBP designed a series of comparative tests to evaluate the effects of Dynasolis™ lighting on human alertness, attention, and relaxation. Approximately 35 test subjects participated in each test series, where they were exposed to different lighting conditions, including standard LEDs (2700K, 4000K, and 6000K, each with CRI 83+) and the Dynasolis™ solution at color temperatures of 2700K, 6000K, and 10000K.

The tests included the Stroop Task for attention evaluation, the AuReTim method for measuring alertness, and the PANAS (Positive and Negative Affect Schedule) test for assessing stress levels and relaxation.

Key Findings

1. Enhanced Attention and Reaction Times

The Stroop Task revealed significant improvements in reaction times when subjects were under the Dynasolis™ 6000K lighting compared to standard 6000K LEDs without cyan light. The inclusion of cyan light in the Dynasolis™ solution resulted in shorter reaction times, indicating improved attention and cognitive performance. Furthermore, subjects responded even faster under Dynasolis™ 10000K, highlighting the positive impact of increased cyan light on attention.

2. Improved Alertness

The AuReTim alertness test demonstrated that color temperature significantly affects alertness levels. Subjects were more alert under higher color temperatures (6000K) compared to lower ones (4000K). This effect was consistent across both standard LEDs and Dynasolis™, but the Dynasolis™ solution provided an additional boost due to its optimized spectrum.

3. Effective Relaxation

To assess relaxation, subjects were first placed in a room lit by standard 4000K LEDs to acclimate. They were then subjected to a stress-inducing cognitive task, followed by a relaxation phase under different lighting conditions. The results indicated that subjects felt more relaxed under 2700K lighting, regardless of whether it was standard LED or Dynasolis™. The Dynasolis™ solution, however, provided equal relaxation benefits while maintaining the advantages of its spectrum tuning.

4. Comprehensive Benefits Across Applications

The study confirmed that Dynasolis™ could meet various human lighting needs more effectively than standard LEDs. Its ability to tune both color temperature and melanopic illuminance makes it a superior solution for applications ranging from workspaces and educational facilities to healthcare and hospitality environments.
