“Much like our package-less WICOP Series LEDs revolutionized the LED packaging process, our SunLike Series LEDs represents a revolution in creating natural spectrum LED lighting.” commented Mr. Chung Hoon Lee, CEO of Seoul Semiconductor.

Designed for next-generation human-centric lighting solutions optimized for circadian rhythms, the new technology combination is claimed to minimize the side-effects of blue-LED-based white lights that typically create a blue light “spike” which may produce negative effects when viewed for prolonged periods during night-time hours by interfering with natural human biorhythms. The use of a purple emitter in combination with a blend of phosphors shares some similarities with Soraa’s white LED technology announced over three years ago, also claiming best sun-like spectrum characteristics.
