Seoul Semiconductor in Toshiba deal for natural light LEDs
Seoul Semiconductor is taking over the SunLike Natural Sunlight Spectrum LED technology patents and business rights from Toshiba Materials.

Seoul Semiconductor in Korea is taking over the technology and patents of the SunLike natural light LEDs from development partner Toshiba Materials.

The SunLike LED technology is optimized for natural human biological rhythm which has 24-hour cycle, and was jointly developed in 2017. The technology needed significant investment and the two companies have been in discussion on the way forward for the last two years.

While the spectrum of products that many lighting companies promote as Human Centric Light, or HCL, is simply lowering the blue light peak, SunLike implements the balance of RGB light closest to the sunlight spectrum using Toshia' phosphor materials on an LED.

Over the last three years, Seoul Semiconductor has conducted memory and learning comparison experiments in the US, Europe and Korea and myopia prevention experiments in Singapore using the SunLike technology. It plans to announce the results in October 2021 and at the CES 2022 exhibition.

Key workers from Toshiba Materials in Yokohama have joined Seoul Semiconductor.

“It is important to select natural light that has been optimized for human DNA for millions of years, not brightness and low price anymore. With SunLike technology, Seoul Semiconductor believe that the technology supports to reduce myopia and helps people fall a sleep well at night when cells are regenerated. Also, by returning the sunlight of nature to mankind, we will become the protagonists of a new history of light,” said Chung Hoon Lee, CEO of Seoul Semiconductor.

Seoul Semiconductor is the world’s second-largest global LED manufacturer and has more than 10,000 patents. The global LED lighting sales market is estimated at US$5bn
