Seoul Semiconductor’s SunLike Series Natural Spectrum LEDs Adopted by Korean Premium Brand for Human-Centric Lighting
ANSAN, South Korea – Seoul Semiconductor Co., Ltd. (KOSDAQ 046890), a leading global innovator of LED technology, announced that its SunLike Series natural spectrum LEDs have been adopted for the Korean premium brand “PureLumi” for a product line which combines the human-centric lighting enabled by the SunLike Series LEDs with an air purifier.
PureLumi is a premium product line that delivers both air purification and smart residential lighting, delivering on the promise of “Healthy Light and Clean Air for Your Space.” The brand has adopted SunLike Series natural spectrum LEDs, as they produce light closest to natural sunlight. The natural spectrum light produced by SunLike Series LEDs delivers beneficial effects on visual comfort and human circadian rhythm control to provide users with health and well-being benefits beyond simple illumination.
Seoul’s SunLike Series natural spectrum LEDs are the world’s first LEDs to produce light that closely matches the spectrum of natural sunlight, delivering human-centric lighting by reaching a lower blue light peak similar to sunlight’s spectral curve, and by reducing scattered reflection and glare. SunLike Series LEDs have been identified as a key light source for promoting human well-being, based on the results of a recent comprehensive sleep study conducted by Prof. Christian Cajochen and his team at the University of Basel in Switzerland. The paper, entitled: “Effect of Daylight LED on Visual Comfort, Melatonin, Mood, Waking Performance, and Sleep,” was published in The Journal of Lighting and Research Technology on March 24, 2019. Quoting from the paper: “We have evidence that a daylight [natural spectrum] LED solution has beneficial effects on visual comfort, daytime alertness, mood, and sleep intensity in healthy volunteers.”
In addition, during July 2018, the Biomedical Information Laboratory at the Seoul National University College of Medicine in Korea conducted research on adults using desk lamps based on Seoul Semiconductor’s SunLike Series natural spectrum LEDs. The researchers found that SunLike Series LEDs resulted in decreased eye discomfort and better sleep patterns. The SunLike Series LEDs have also achieved the highest level of eye safety certification from the International Commission on Illumination as an RG-1 level light source with no photo-biological risks.
The light sources with SunLike Series LEDs more accurately show the color of objects as they would appear in natural sunlight. Optimized to natural light spectra and color rendering of CRI-97 – close to CRI-100 of sunlight, and higher than the CRI-80 of conventional LEDs – SunLike Series LEDs deliver considerable benefits in significant vivid color, detail contrast, and consistent quality of light.
“As the paradigm of lighting shifts to human-centric lighting, there is an increasing demand for healthy light sources for people who spend a lot of time indoors,” said Nam Ki-bum, sales executive vice-president of Seoul Semiconductor. “Light sources with SunLike Series LEDs certainly bring differentiated value to the lighting industry, compared to conventional LEDs. We will expand the global market for customers and consumers who wish to experience our human centric lighting solutions.”
Seoul Semiconductor developed SunLike Series natural spectrum LEDs in collaboration with Toshiba Materials’ TRI-R spectrum technology in 2017 as the first LED light source to closely match the spectrum of natural sunlight.
