The GETonLight system provides complex, controllable LED lighting with adjustable color temperature, patterns, and intensity, creating artificial lighting that can simulate natural daylight. The controllable color temperature means that the LED lamps are capable of illuminating the space with light of a wavelength similar to sunlight, influencing the human body's melatonin system. This activation helps energize individuals in the room. Before completing activities, it's possible to adjust the light intensity to a lower level, using light similar to twilight, which relaxes and prepares individuals for efficient rest and good sleep. Essentially, the system can simulate natural sunlight, providing pleasant light for people in a controllable manner—activating individuals in the room only to the extent that is optimal, adjustable based on activity type.

The system was tested on basketball players, volleyball players, and gymnasts at the University of Physical Education with the involvement of Dr. Zsombor Lacza, the scientific vice-rector. As a result of the two-year project, it can be stated that the GET lighting system is capable of increasing performance and concentration by 10%.

After numerous Hungarian publications on the results, a publication accepted by the scientific committee was presented at the prestigious ECSS conference in Paris on July 6, 2023:

Tamás Várhelyi, Zoltán Boros, Zsombor Lacza, Mira Ambrus: An innovative complex sports lighting system and the related options for the enhancement of sports performance.

In the 21st century, characterized by accelerated pace and technology-driven life, our lives are increasingly intertwined with artificial lighting. Whether we work, study, or relax, the type of lighting we encounter fundamentally influences our general well-being. Human Centric Lighting (HCL) has revolutionized our approach to lighting, taking into account the biological needs and rhythms of humans, thereby improving our well-being. We supplemented this technology with scientific research within the framework of the GETonlight project, making our lives more natural, healthier, and more harmonious.

Understanding Human Centric Lighting:

Human Centric Lighting is not just a buzzword; it represents a paradigm shift in lighting design. Traditional lighting systems often focus solely on functionality and aesthetics, disregarding the importance of biological reactions to human light. In contrast, HCL is based on a deep understanding of our circadian rhythm – our body's natural cycle in response to daylight and darkness. By simulating the natural changes of sunlight throughout the day, HCL aims to support our biological needs, improving mood, productivity, and overall well-being.

The Effects of Light on Our Bodies and Minds:

Over millennia, the human body has evolved to synchronize with the natural light-dark cycle. This internal clock, known as the circadian rhythm, regulates various physiological processes, including sleep-wake cycles, hormone production, and metabolism. Traditional lighting, often characterized by harsh, static light sources, can disrupt our circadian rhythm, leading to sleep disorders, mood disturbances, and decreased cognitive performance.

Benefits of Human Centric Lighting:

As mentioned, Human Centric Lighting refers to lighting systems designed to consider individuals' biological and emotional needs, promoting well-being, productivity, and comfort. Here are some benefits of implementing Human Centric Lighting:

1) Improved Sleep Quality:

One of the significant advantages of HCL is the opportunity to improve sleep quality. Exposure to blue-enriched light during the day helps maintain alertness and enhances cognitive abilities. However, excessive blue light in the evening can disrupt the production of melatonin, the sleep hormone, making it difficult to fall asleep. HCL systems address this issue by gradually reducing blue light content in the evening, promoting the natural winding-down process and improving sleep quality.

2) Enhanced Mood and Mental Well-being

Natural daylight has long been associated with positive effects on mood and mental well-being. HCL mimics the dynamic changes of natural light, contributing to the regulation of serotonin levels—the "feel-good" hormone. This can help alleviate symptoms of depression and seasonal affective disorder (SAD), leading to increased happiness, energy, and reduced susceptibility to mood swings.

3) Increased Productivity and Focus:

In work environments, Human Centric Lighting can significantly influence productivity and focus. The bright, cool-toned light characteristic of natural midday sunlight stimulates alertness and concentration in the morning and early afternoon, optimizing our performance. As the day progresses, warmer and softer light settings induce calmness, reduce stress, and enhance creativity.

4) Improved Visual Comfort and Reduced Eye Strain:

GETonLIGHT utilizes advanced optical and lighting control systems to minimize glare and provide uniform illumination throughout the space. This effectively reduces eye strain and visual discomfort, particularly beneficial for individuals who spend prolonged periods in front of screens or participate in presentations, creating a healthier and more comfortable environment. GETonLIGHT intensity adjustments enhance well-being and productivity, making modern lighting solutions preferred choices for such applications.

5) Energy Efficiency and Cost Savings:

While Human Centric Lighting encompasses dynamic adjustments to meet changing lighting needs, integrating intelligent controls and state-of-the-art sensors is crucial to ensuring thoughtful and on-demand lighting usage. This intelligent optimization not only results in significant energy savings but also effectively reduces operational costs, making HCL a sustainable and cost-effective lighting solution for both commercial and residential applications. Adapting to changing environmental conditions and responding to them further enhances the overall efficiency of GETonLight, benefiting both users and the environment.
