News: LEDs
28 July 2020
South Korean LED maker Seoul Semiconductor Co Ltd says that its SunLike Series natural-spectrum LEDs have been adopted by traditional Japanese lighting company Koizumi Lighting Technology Corp for use in lights for children’s rooms and living rooms. SunLike Series natural-spectrum LEDs are optimized to support healthy circadian rhythms based on natural sunlight, under which all animals and plants have evolved over 3.9 billion years.
Seoul Semiconductor claims that, in contrast to conventional LEDs, SunLike Series LEDs have three beneficial effects: Eye Better – protection from myopia in children; Study Better – support for students’ learning and concentration; and Sleep Better – improvement in sleep quality.
Based on the results of a sleep study conducted by professor Christian Cajochen and his colleagues at the University of Basel in Switzerland, LED light sources with the same measured intensity and correlated color temperature (CCT) but different spectral output can have different effects on human behavior and physiology. Published in the Journal of Lighting & Research Technology on 24 March 2019, the study found “evidence that daylight [natural spectrum] LED solution has beneficial effects on visual comfort, daytime alertness, mood, and sleep intensity in healthy volunteers.”
According to the results of a study by the Bio-Information Laboratory of Seoul National University Hospital in July 2018, SunLike Series natural-spectrum LEDs have been shown to reduce eye discomfort and improve sleep patterns.
Improved sleep has recently become more important in the midst of the COVID-19 pandemic. Various studies show that high sleep quality can boost immunity, enhancing the ability to resist a particular infection or toxin.
“Our SunLike Series natural-spectrum LEDs are an advanced technology that has achieved the highest level of eye-safety certification from the International Commission on Illumination as a safe light source with no photo-biological risks,” says Seoul Semiconductor. “In particular, it helps improve eye comfort and concentration for children.”
Introduced in June 2017, SunLike Series natural-spectrum LED light sources combine Seoul Semiconductor’s latest optical and compound semiconductor technology with Toshiba Materials’ TRI-R technology.
