Seoul Semiconductor’s SunLike range of natural spectrum LEDs, first announced in 2017, have gone on to be recognised as an innovative technology for human-centric lighting at global lighting awards held in Europe, China and USA.
Based on TRI-R technology developed by Toshiba Materials, the LEDs are designed to deliver light that closely matches sunlight’s natural spectrum, to provide an optimised light source that maximises the benefits of natural light. Thus, the colours and texture of objects can be viewed more accurately, as they would be seen under natural sunlight.
Seoul Semiconductor believes its SunLike LEDs may also play a key role in minimising the negative effects of artificial lighting. While conventional LED technology produces light with a pronounced blue spike in its spectral output, SunLike LEDs implement a more uniform spectrum that more closely matches natural sunlight, lowering this blue light spike.
Some recent research indicates that this blue light spike may produce negative effects when viewed for prolonged periods of time during night-time hours, potentially interfering with natural human biorhythms. By employing new light sources powered by SunLike LEDs, lighting designers could be able to deliver a healthier light experience.
Interest in the link between light sources and human health is higher than ever before, as evidenced by the winners of the 2018 Nobel Prize in Physiology: Professor Jeffrey C. Hall, University of Maine; Professor Michael Morris Rosbach, Brandeis University; and Professor Michael Young, Rockefeller University. These researchers are credited with seminal discoveries about the cellular mechanisms for circadian biology.
