According to reports, the clinical trial started in 2019 and was conducted by the Division of Sleep and Circadian Disorders at the Brigham and Women's Hospital, an affiliated teaching institution of Harvard Medical School. The author is a college-level adult, and the results of the study clearly show the effectiveness of program learning.
Compare the cognitive performance exposed to traditional LED lighting or SunLike LED lighting
Researcher at the Sleep and Circadian Disorders Department at Brigham and Women's Hospital, Dr. Shadab Rahman, Assistant Professor of Medicine and Master of Public Health at Harvard Medical School, and Dr. Leilah Grant and Melissa St. Hilaire from Brigham Hospital Dr. Steven Lockley, Dr. Steven Lockley, and other researchers led the research together.
Dr. Rahman said that even if the color temperature and brightness are the same, different spectrums of light may affect non-visual responses to light in different ways, including circadian rhythms and cognition. In this experiment, the researchers found that under sunlight-like spectral lighting, young people’s working memory, cognitive processing speed, program learning and test accuracy are improved compared to traditional LED spectral lighting. This important result can provide information for indoor lighting options to enhance students' learning and memory functions.
The fluorescent spectrum lamp used in the study is a SunLike product manufactured and provided by Seoul Semiconductor. SunLike is an optical semiconductor technology that can reproduce natural light spectrum curves of various wavelengths such as red, orange, yellow, green, cyan, blue, and purple. This new concept of LED light source embodies almost the same characteristics as natural light, and accordingly optimizes the human 24-hour circadian rhythm.
Nowadays, research on the relationship between light and human biological functions is increasing. A recent study by Professor Christian Cajochen and his team on the effects of light spectrum on sleep quality, visual comfort, health and daytime alertness found that sunlight LED is beneficial to visual comfort, melatonin, mood, waking performance and sleep. The research was published in the Journal of Lighting and Research Technology on March 24, 2019.
In addition, an experiment conducted at Seoul National University School of Medicine in July 2018 showed that the use of SunLike LED lights can increase vitality and alertness.
Spectral comparison under the same shape and color lighting conditions
Said Lee Jeong-hoon, CEO of Seoul Semiconductor. Nature is great. The human body has a 24-hour biological clock. It has evolved to set the time by tracking the cycle of daily sunlight. SunLike is a technology that can reproduce all visible light wavelengths as close to the sun as possible. Publicity is committed to research and development to provide plants, animals and humans with the light that is closest to the sun, which helps maintain the circadian rhythm and sleep, and can also help children and students learn effectively and maintain good health.
It is reported that Seoul Semiconductor and Toshiba Materials jointly participated in the development and listing of SunLike in 2017. In the past two years, the two companies have conducted continuous negotiations in order to improve the decision-making speed and operational efficiency of the SunLike business. Seoul Semiconductor has obtained all technologies, patents, trademarks, etc. related to SunLike, the light closest to the sun. The core staff of Toshiba Materials also joined Seoul Semiconductor, and started to expand sales in September.
