Chung Hoon Lee, CEO of Seoul Semiconductor, speaks at a special press conference in Frankfurt, unveiling the new SunLike technology.

(Germany) – Seoul Semiconductor and Toshiba Materials’ new SunLike technology matches the spectrum of natural sunlight, contributing to a healthier life for humans.

At a special press conference in Frankfurt, Germany, held on June 26th, Seoul Semiconductor unveiled SunLike, a new LED technology developed alongside Toshiba Materials that produces light that closely matches the spectrum of natural sunlight.

The SunLike Series LED technology closely matches the spectrum of natural sunlight that human have enjoyed for thousands of years. It maximises the advantage of natural light and minimises the shortcomings of artificial light sources, providing light more like natural sunlight. This natural spectrum of light is achieved by combining Seoul Semiconductor’s world-class LED chip technology with Toshiba Materials’ TRI-R technology, a leading global phosphor compound.

“We are pleased to introduce another South Korean innovation in LED technology with the launch of the SunLike Series LED lighting technology. Our SunLike Series LEDs represents a revolution in creating natural spectrum LED lighting,” said Chung Hoon Lee, CEO of Seoul Semiconductor. “The SunLike Series LEDs will be applied in the lighting sector, contributing to a better and healthier life for humans. They will also be used in horticultural applications to create an ideal environment to help plants grow that is safer than using genetic modification.”

He added: “We are delighted to partner with Toshiba Materials to provide our customers a light source that delivers the natural spectrum of sunlight – from the brightness of morning sunshine, to the energy of daylight, to the warmth of an evening sunset. We believe that the SunLike Series LEDs will improve the quality of human life by advancing a new era of human-centric lighting technology.”

Because SunLike Series LEDs are designed to deliver light that closely matches the natural spectrum of sunlight, they provide an optimised light source for human-centric lighting that maximises benefits of natural light while minimising the negative side effects of artificial light sources.

Some recent studies have suggested that blue LED chips, used in most commercial LEDs to create visible light, provide positive stimulation to the human eye that increases alertness and elevates mood when viewed during daytime hours. However, these blue LEDs create a blue light ‘spike’ in the light output of an LED that may produce negative effects when viewed for prolonged periods during nighttime hours by interfering with natural human biorhythms. Alongside this, excess blue light can over-stimulate the retinal cells in the eye, and may cause eyestrain and loss of concentration.

The SunLike Series’ natural spectrum LED technology employs a purple LED in conjunction with the TRI-R phosphor compound to minimise the blue light spike that is characteristic of typical LED light sources, producing a light output that closely matches the spectrum of natural sunlight to deliver a healthier light experience.

The SunLike Series is available now, and Seoul Semiconductor expects to see installations by the end of the year.
