Control of Spectral Power Distribution for High CRI and CQS

2013/12 Chih-Wei Lin, Ke-Fang Hsu, and Jung-Min Hwang

Abstract— In this study, an evaluation method for high color rendering index (CRI) and color quality scale (CQS) using multi-LED spectral power distribution is proposed. Red and amber-colored LEDs were used to enhance the properties of a 4000 K white LED up to CRI 90 and CQS 80. The results
of this research could be used in LED lighting design to achieve high lighting quality.
Index Terms—CRI, CQS, SPD, LED.
