Seoul Semiconductor’s SunLike Series natural-spectrum LEDs adopted by lighting brand REMEZ

South Korean LED maker Seoul Semiconductor Co Ltd says that its SunLike Series natural-spectrum LEDs have been adopted for lighting brand ‘REMEZ’ by RemiLicht GmbH for the Russian lighting market. The LED light bulbs feature a human-centric lighting design enabled by the SunLike Series LEDs.

The SunLike Series LEDs adopted by RemiLicht (for LED light bulbs for residential lighting and desk lamps) achieved warm-white (3000K) and cold-white (5700K) correlated color temperatures (CCTs), optimized to natural light spectra by reaching lower blue light peak similar to sunlight’s spectral curve in order to reduce scattered reflection and glare common in conventional LEDs.

Seoul says that its SunLike Series natural-spectrum 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 professor Christian Cajochen and his team at the University of Basel in Switzerland (‘Effect of Daylight LED on Visual Comfort, Melatonin, Mood, Waking Performance, and Sleep’, Journal of Lighting and Research Technology, on 24 March). “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,” Cajochen says.

Light sources with SunLike Series LEDs are said to more accurately show the color of objects as they would appear in natural sunlight. Optimized to natural light spectra and color rendering index of CRI-97 (close to the CRI-100 of sunlight, and higher than the CRI-80 of conventional LEDs), it is claimed that SunLike Series LEDs deliver significant benefits in vivid color, contrast detail, and quality of light consistency.

“We have sought LED light sources to replicate the qualities of natural sunlight for indoor environments to deliver beneficial effects on eye comfort and human health,” says RemiLicht’s CEO Igor Remez. “We were able to create LED light bulbs for human-centric lighting with Seoul Semiconductor’s innovative SunLike Series LEDs, which will deliver healthy light that were not possible to achieve using conventional LED technology,” he adds.

“Even if different sources of white light look identical to the naked eye, they may contain different levels of the crucial wavelength in the blue spectrum that triggers the body’s hormonal response,” says Carlo Romiti, Europe sales VP at Seoul Semiconductor. “A truly human-centric lighting source must not only closely match the spectrum of natural sunlight but it also must have the correct level of blue-wavelength light for the time of day,” he adds. “Our SunLike Series LEDs enable truly human-centric lighting design that closely matches the spectrum of natural sunlight. It has 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.”

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.
