ANSAN, South Korea–()–The world-leading LED company Seoul Semiconductor (Head office:
Ansan-si, Korea, CEO: Chung Hoon Lee, hereinafter Seoul Semiconductor)
announced that SunLike, which implements light which comes closest to
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
amongst 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 eye sight may be impaired if
stared at directly and there has to be a warning label on the finished

SunLike received the RG-1 grade in Eye Safety certification with its
natural light LED which applies TRI-R technology from Toshiba Materials
(Head office: Yokohama city, Kanagawa Prefecture, CEO: Aoki Kokumei).
The RG-1 grade is granted to a safe light source for which there is no
biological risk, even if our entire lives were spend exposed to the
light source. Particularly, the acquisition of the RG-1 grade for the
first time for a 25 W 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 light LED SunLike, which
acquired the RG-1 grade in Eye Safety certification, is in the spotlight
as a next generation light source.

In addition, SunLike doesn’t have the blurring problem occurring in most
other artificial light sources and as a result, the unique color an
object has comes out the best and the three-dimensional effect of the
object remains intact. Thanks to these features, SunLike is expected to
be widely applied, not only in places requiring a healthy lighting
environment such as home, offices, schools, medical institutions, etc.,
but also commercial facilities, museums, clothes stores, distribution
stores, etc. 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 or Medicine by
the scientists researching biorhythms and consequently also the volume
of inquiries for SunLike from commercial, industrial and medical
institutions, as well as customers in lighting, 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 LED
SunLike which comes closest to the spectrum of sunlight as human beings
have enjoyed for thousands of years.”

TRI-R is a registered trademark of Toshiba Material Co., Ltd. It is a
natural light LED light source technology that reproduces the solar

*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 the luminaire was widely used for LED, 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.

[Risk Classification Table]

Risk Group   Risk
No Risk (Exempt) No photobiological- risk
RG 1 (Low Risk) No photobiological risk in normal daily life
RG 2 (Intermediate Risk) Doesn’t cause risk but feels unpleasant due to bright light or heat
RG 3 (High Risk) Dangerous even if a human is exposed to light instantaneously
