Recently, an academic seminar was held during the Frankfurt Lighting and Architecture Exhibition (L&B), which scientifically and objectively elucidated the impact of light on health and circadian rhythms, causing a sensation among academia and industry insiders. L&B is the world's largest lighting exhibition. On March 29th, Seoul Semiconductor, the first professional LED manufacturer in South Korea, announced the successful holding of an academic seminar on the theme of "Human Factors Lighting and Health" during the 2018 L&B.
Seoul Semiconductor Company has invited some experts, including Professor Russell Foster from Oxford University, Dr. Manuel Spitschan from Oxford University, and Dr. Octavio L. Perez from Mount Sinai Hospital in New York, who are recognized as leading authorities in the study of light, sleep, and physiological rhythms. Three experts introduced the impact of light on human sleep, health, and physiological rhythm, and discussed the future direction of lighting.
Professor Russell Foster, the most important expert in the field of light, sleep, and circadian rhythms, said, "Light not only allows us to perceive space, but also plays a crucial role in controlling our circadian rhythms and sleep to perceive time. He added, "In order to maintain a healthy and happy life, we must get the best possible sleep and maintain our circadian rhythm at the optimal level. We also need to replace the artificial lighting systems that currently affect our circadian rhythm with more human-centered lighting
Dr. Manuel Spitschan from the University of Oxford emphasized in his speech the impact of light on the circadian rhythm of our body. He said, "Light has an extremely important impact on the eyes and brain, because there is something called a photoreceptor in our ganglion cells, which is located in the retina of our eyes. These photoreceptors perceive red, green, and blue light and receive color spectra to varying degrees. Dr. Spitschan also said, "In particular, essentially photosensitive retinal ganglion cells (IpRGCs) are directly connected to the brain, transmitting signals from light to the brain, and are more sensitive to blue light at specific wavelengths. When these cells are activated, our body slows down the production of melatonin, a hormone that regulates sleep, and its reduction affects our 24-hour circadian rhythm.
Meanwhile, Dr. Octavio Perez from Mount Sinai Hospital in New York talked about the importance of sunlight, next-generation building standards, and the excellence of SunLike technology. OctavioPerez said, "Generally speaking, people living in well lit buildings are healthier and happier in their lives compared to those living in artificially lit indoor spaces. This is because the spectrum of artificial light is significantly different from that of natural sunlight.
He continued, "Artificial light like fluorescent lamps and light-emitting diodes emit irregular spectra of light waves, affecting the user's circadian rhythm and vision. In the long run, it has a negative impact on the human body. And SunLike's spectrum is as close to that of sunlight as possible, which means it has great benefits in protecting the eyes and reproducing colors. It is the ideal lighting in architecture, so I hope it will be more popular in the future lighting field.
Dr. OctavioPerez also pointed out that developing SunLike lighting fixtures using natural light will completely change future building standards and designs. Not only that, the construction industry will also implement stricter standards to provide people with high-quality light like sunlight. Therefore, enterprises must focus on developing and producing natural light fixtures. SunLike is a natural light LED product jointly developed by Seoul Semiconductor and Toshiba Materials. SunLike won a gold medal at the 2018 Product Awards hosted by the German electronic parts magazine Elektronik, in recognition of its best innovation and technology. Elektronik "is a renowned electronic and electrical magazine in Germany with a long history and the highest number of subscribers.
According to researchers who won the 2017 Nobel Prize in Physiology, identifying genes that control circadian rhythms controls all major functions of our body, such as human behavior, hormone levels, sleep, body temperature, and metabolism. It is the same in the cells of all multicellular organisms, including plants, animals, and humans. He said, "This is a great research achievement that clearly demonstrates how important it is to maintain the 24-hour periodic rhythm formed by the sun.
He continued, "This seminar provides scientific and objective evidence on the impact of light on our circadian rhythm, sleep, and health. This is a meaningful discussion that can raise people's awareness and awareness of the importance and necessity of lighting devices that provide natural light, and reflect on the future direction of lighting.” He added, "SunLike reproduces light as close to sunlight as possible and is being hailed as the next generation of light sources, leading a new era of human factor lighting. Therefore, we will do our best to increase the supply of SunLike around the world.
