Seoul Semiconductor Unveils 'SunLike' Series of Natural Spectrum LEDs That Enable Human-Centric Lighting

By Roger ElliottJuly 10, 2017

Seoul Semiconductor — a global manufacturer of light emitting diodes (LEDs) and backlighting units (BLU) for automotive, mobile, signage, and lighting applications — unveiled the 'SunLike'. A new LED technology developed in collaboration with Toshiba Materials that closely resembles the spectrum of natural sunlight, the SunLike Series was introduced at a press conference in Frankfurt, Germany.

The SunLike Series combines Toshiba Materials’ TRI-R technology alongside Seoul Semiconductor's LED chip technology to achieve the natural spectrum of light. The high-class natural spectrum LEDs optimize the benefits of natural light while minimizing the ill effects of artificial light sources, producing a light output that is more like the natural sunlight.

“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.”

Blue LED chips, as revealed by some recent studies, create highly visible light that provides positive stimulation to the human eye, elevates the mood, and enhances alertness during daytime hours. However, it has been also observed that blue LEDs generate a blue light ‘spike’, which by interfering with the natural human biorhythms can produce negative effects like eye strain if viewed for prolonged hours during the night time.  

Seoul Semiconductor's SunLike Series, in order to minimize the blue light spike, employs TRI-R phosphor compound in conjunction with a purple LED to deliver healthier, strain-free light experiences which almost matches the spectrum of natural sunlight.

Key Applications and Market Forecast of Seoul Semiconductor's 'SunLike' Series of Natural Spectrum LEDs

The SunLike Series of natural spectrum LEDs is ideal for cosmetic and horticulture facilities, commercial and exhibition centers such as department stores, museums, airports, stations, and exhibition halls that require distinct visibility of colors even when viewed under sunlight.

This overall segment of the LED market where the SunLike Series of natural spectrum LEDs can be applied accounts for $17 billion. Seoul Semiconductor's SunLike Series will be initially deployed in commercial applications that require high-quality lighting, and then the LEDs will eventually find its place in general lighting, a market of $35 billion globally.

The SunLike Series of natural spectrum LEDs is now available at WPG Americas. Please visit Seoul's SunLike site to learn more about the revolutionary LED technology or you can also contact WPGA Lighting Specialist Roger Elliot for more information.
