Seoul Semiconductor’s SunLike Series Natural Spectrum LEDs Applied in Xiaomi Yeelight’s Smart Lamp

– SunLike Series LEDs have been adopted for the Yeelight Smart Lamp,
which features smart controls for adjustable study hours, color, and
brightness

– SunLike LEDs provide healthy and comfortable light that closely
matches the spectrum of natural sunlight for children using desk lamps

ANSAN, South Korea–(BUSINESS WIRE)–$KOSDAQ046890 #Acrich–Seoul Semiconductor, a global innovator of LED products and technology,
announces that its SunLike Series natural spectrum LEDs, which
implement light that closely matches the spectrum of natural sunlight,
continues to expand its global application base. Seoul Semiconductor
announced that Yeelight, a leader in the intelligent lighting industry
and part of Xiaomi’s ecosystem, has adopted Seoul Semiconductor’s
SunLike Series natural spectrum LEDs as a light source for its Yeelight
LED Desklamp Pro, a lamp that provides adjustable control of study
hours, light colors and brightness control (dimming) via its smartphone
application, and is compatible with both Amazon Alexa and Google
Assistant applications.

Yeelight’s LED Desklap Pro was designed for an ambitious launch into the
global smart desk lamp industry by the company, which has a management
philosophy of innovating lighting interaction to deliver the most
comfortable light through superior technology. Combining Yeelight’s
state-of-the-art application control system and Seoul Semiconductor’s
SunLike natural spectrum LED technology, consumers can experience light
that closely matches the spectrum of natural sunlight.

Yeelight’s LED Desklamp Pro features user-controllable light modes for
intensive studying, as well for vision protection. Equipped with
Yeelight's scientific vision protection and study time setting programs,
the lamps enable consumers to control these settings through a dedicated
mobile phone application, and supports major smart home systems, such as
Amazon Alexa and Google Assistant.

Through the use of a pulse width modulation (PWM) filter circuit for the
analog signal module, the Desklamp Pro effectively controls light
flickering, which relieves eye fatigue and may reduce the incidence of
myopia (near-sightedness), which occurs more frequently in children who
are not exposed to sunlight for extended periods of time.

Yeelight CEO Jiang Zhaoning, explained, "Yeelight has been leading the
market by actively developing innovative lighting systems in partnership
with leading partners around the world to provide the most comfortable
and relaxing lighting products to consumers. We strive to provide
consumers with the safest and healthiest light by working together with
Seoul Semiconductor, the innovator of SunLike LED technology, which
implements light that closely matches the spectrum of natural sunlight.
We believe that thousands of people will experience this differentiated
light source with the Smart Desklamp Pro that combines these two
companies’ leading technologies."

Caleb Won, executive VP of global marketing group at Seoul
Semiconductor, said, “Conventional LED desk lamps currently being used
in homes can have potentially negative effects on children's eye health
through prolonged exposure to excessive amounts of blue light at certain
wavelengths. SunLike Series natural spectrum LEDs represent the next
generation natural light LED technology that has achieved the highest
level of eye safety certification from the International Commission on
Illumination, recognizing SunLike LEDs as an RG-1 level light source
with no photo-biological risks. While various attempts have been made to
reduce blue light to protect eyesight (such as installing a lens cover),
they did not provide a fundamental solution. By implementing light that
closely matches the spectrum of natural sunlight, SunLike Series LEDs
are an ideal solution to enhance children's eye health and contribute to
an optimal learning environment."

Prolonged exposure to excessive blue light can disrupt sleep patterns
and has the potential to negatively effect eyesight, because the retinal
cell that detect light in the blue wavelength comprise only 5.7% of all
human retinal cells. SunLike LED technology, however, implements light
with a spectrum that closely matches natural sunlight, providing
children with the healthiest and most comfortable light, improving their
environment for learning, reducing eye fatigue, and displaying colors
and textures more accurately.

SunLike Series natural spectrum LEDs were co-developed by Seoul
Semiconductor and Toshiba Materials. They combine Seoul Semiconductor’s
optical semiconductor technology and Toshiba Materials’ TRI-R Technology
that produces light closer to the spectrum of natural sunlight.
