Seoul Semiconductor announced that SunLike Series LEDs, which implement light that closely matches the spectrum of natural sunlight, received an RG-1 Eye Safety certification based on the safety of its light source and was recognized for the highest level of safety among 25W COB type LED.
Eye Safety certification is a rating based on safety from analyzing the LED wavelengths. In Europe, where top priority is placed on the safety of lighting, Eye Safety certification is essential and the light source must be higher than RG-3 level, otherwise eyesight may be impaired if the light source is stared at directly and requires a warning label on the finished product.
SunLike received the RG-1 rating in Eye Safety certification for its natural light LEDs, which apply TRI-R technology from Toshiba Materials (Head office: Yokohama city, Kanagawa Prefecture, CEO: Aoki Kokumei). The RG-1 rating is granted to safe light sources which carry no biological risk, even with lifetime exposure. Particularly, the acquisition of the RG-1 rating for the first time for a 25W single light source widely used for commercial and residential lighting is highly significant, as a natural light source with the highest level of safety has been commercialized.
The interest in the impact of light on health has increased tremendously with the award of the Nobel Prize in Physiology or Medicine to professor Jeffrey C. Hall from Maine University, professor Michel Rosbash from Brandeis University and professor Michael Young from Rockefeller University of USA, acknowledging the causal relationship between biorhythms and human health. So the natural spectrum SunLike LEDs, with an RG-1 grade in Eye Safety certification, are in the spotlight as a next-generation light source.
In addition, SunLike LEDs eliminate the blurring problem occurring in most other artificial light sources and as a result, the unique color of an object and three-dimensional texture of the object remains intact. Thanks to these features, the SunLike Series LEDs are expected to be widely applied, in places requiring a healthy lighting environment such as homes, offices, schools, medical institutions, as well as commercial facilities, museums, clothing stores, department stores, which have to reproduce the natural color and texture of the object.
“Interest in the relationship between light and human health is increasing with the award of Nobel Prize in Physiology to the scientists researching biorhythms, and consequently there has been an increase in inquiries for SunLike LEDs from commercial, industrial and medical institutions, as well lighting designers throughout the world,” according to Dr. Kibum Nam, Head of Seoul’s R&D Center and Chief Technology Officer. “We are opening the healthy lighting era of natural light thanks to SunLike Series LEDs, which implement light that closely matches the spectrum of natural sunlight that human beings have enjoyed for thousands of years.”
