In 2011, ERFC scientist Jeff Tsao, in conjunction with Roland Haitz and Taiming Zhou, published an SSLS paper titled, “Solid-state Lighting: ‘The Case’ 10 Years After and Future Prospects”. The paper critiques a previously released white paper titled, “The Case for a National Research Program on Semiconductor Lighting” while providing new predictions for the next coming 10-20 years in the field of solid-state lighting. The paper will be published in Chinese, making it accessible to a larger scientific audience.

Abstract: Ten years ago, a white paper titled “The Case for a National Research Program on Semiconductor Lighting” outlined the promise of semiconductor light-emitting diodes (LEDs) for general illumination. Since then, investments in the now-renamed field of solid-state lighting (SSL) have accelerated and considerable progress has been made, not always in the directions envisioned at the time. In this paper, two of the original four authors comment on the white paper’s hits and misses, while making the original white paper available archivally as supplemental online materials. Finally, we make predictions for the coming 10-20 years.
