Abstract：This study proposes a multispectral dynamic regulation technique based on five-channel LED color mixing to address the diversified color-rendering requirements of merchandise in commercial lighting scenarios and the problems of color distortion and narrow color gamut in existing technologies.By constructing a comprehensive color-rendering evaluation model(Ra,Rf,Rg,color tolerance,hue ring offset,and overall luminous efficacy)and combining a metameric tuning algorithm,high-quality spectral solutions for different color categories were developed.Experimental results show that the optimized spectrum has a color rendering index Ra ≥85,color gamut index Rg ≥ 105,and color tolerance≤5 at color temperatures of 3 000 K,4 000 K,5 000 K,and 6 500 K,significantly enhancing the visual appeal of merchandise and consumer preferences.This study provides a theoretical basis for spectral design in commercial lighting and successfully develops high color-rendering lamps with potential for industrial application.
