Seoul Semiconductor Supplies SunLike LED, a Natural Light Reproduction Technology, to KOIZUMI's Learning Lighting

Seoul Semiconductor Co., Ltd. (KOSDAQ 046890), a global optical semiconductor company, announced on the 2nd that it supplied SunLike, a natural light LED, to KOIZUMI FURNITECH Technology Corp., a Japanese learning furniture company. KOIZUMI FURNITECH, a company specializing in traditional Japanese learning furniture, is an affiliated company of Koizumi Group, same as Koizumi, a premium lighting company.

Seoul Semiconductor has been supplying SunLike technology to KOIZUMI lighting company. SunLike technology was already applied to KOIZUMI's children's room lighting and living room lighting in July 2020, and this time it was applied to desk light (ECL-111 and ECL-112) that helps create an optimal learning and reading environment.

SunLike technology is the world's first LED solution unique to Seoul Semiconductor that reproduces the spectrum curve of natural light. In recognition of its technology as the most similar lighting to natural light, it has won the highest diamond grade from Underwriters Laboratories (UL), an international lighting certification body. In addition, in a study at Seoul National University in Korea, Basel University in Europe, and Harvard Medical School led by Dr. Shadab Rahman, it was proven that the use of lighting with SunLike technology improves learning abilities such as working memory, problem-solving accuracy, learning speed, and cognitive processing speed.

Humans control the secretion of melatonin, a biological hormone, by using the wavelength of light entering through the eyes. Decrease of melatonin secretion results in vigorous physical activity and improvement of concentration, while increased secretion stabilizes human circadian rhythm and makes the body rest. The use of morning-light applied with SunLike technology promotes brain activity, helping improve children's concentration and learning speed, and evening-light provides a comfortable rest.

KOIZUMI FURNITECH's desk light with SunLike provides three colors: morning-light (Natural white + Warm white color) for concentration, Afternoon-light (Natural white color) for cognitive processing speed, and evening-light (Warm white color) for relaxation. In addition, there is a 45-minute timer function tailored to the class hours of elementary school students, which helps keep the ?learning and rest cycle.'

"Since COVID-19 has reduced outdoor activities of children and students and made them spend a lot of time indoors away from sunlight, the importance of lighting has been highlighted," an official from Seoul Semiconductor said. "We expect SunLike, which reproduces sunlight, to help many children's eye health and learning effects."

Seoul Semiconductor has supplied SunLike technology to desk lamps for several lighting companies, including: ?The Light' of Balmuda, Japan, ?Prism,' ?BY THE M,' and ?Cozy Light' of Korea, ?Xiaomi' of China, and ?Rang Dong' of Vietnam.
