【摘要】 根据色度学基本原理,对荧光粉转换白光发光二极管(LED)和两基色、三基色白光LED进行了配色计算,得到了距离理想白光点色度坐标(1/3,1/3)小于0.5%范围内的众多基色组合,同时对光视效能、显色指数和荧光粉转换效率等参数进行了分析,提出了荧光粉转换白光LED和两基色、三基色白光LED的最佳基色组合,并在实验上对荧光粉转换白光LED进行了验证。更多还原

【Abstract】 In this paper,we calculated the color matching of white LEDs based on phosphor converted,two primary colors and three primary colors according to colorimetry. Many color combinations whose chromaticity coordinates deviate from the equal energy white point (1/3,1/3) not more than 0.5% have been obtained. We used luminous efficacy and color rendering as standards in the evaluation of them by a program simulation and obtained the best combinations which supported by experiment.更多还原
