Seoul Semiconductor’s SunLike Series LEDs receive the highest level of safety among 25W COB type LEDs with RG-1 Eye Safety certification rating based on light source safety


Ansan, South Korea — The world-leading LED company 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.

What is Eye Safety?

Eye Safety refers to the international standard the International Commission on Illumination adopted as standard (CIE S 009:2002), which defines the standard of LED illumination for the purpose of safety for the eyes and skin. The relevant standard is defined in IEC/EN 62471. Since LEDs became widely used in luminaires, the assessment of risks to blue light became integral and the standard of IEC/EN 62471 began to apply to lighting and system using LED from September the 1st, 2009.
