ABSTRACT This study attempts to quantify and optimize the luminous efficacy of radiation (LER) of trichromatic light sources in both photopic and mesopic visions. A new chromaticity-guided rather than spectrum-guided optimization approach is provided. LER contour maps formed by the gamut area of the three light source units are drawn in the chromaticity diagram. Based on these, functional models of LER in photopic and mesopic visions as well as scotopic/photopic (S/P) ratios are established as a function of chromaticity coordinates. Increasing trends for LER and S/P ratios in corresponding contour maps are proposed, which allow quick estimation and synthesis for ideal performance. By using the functional model, the ideal LER, S/P ratio of trichromatic light sources, and their combinations can be achieved. Based on this work, tunable combinations of LER and S/P ratios with chromaticity information can be achieved, which could provide more application possibilities for trichromatic light sources.

量化三色光源以实现可调谐的明视和中视光辐射效率

摘要 本研究试图量化和优化三色光源在明视和中视视觉中的辐射发光效率 (LER)。提供了一种新的色度引导而非光谱引导的优化方法。色度图中绘制了三个光源单元的色域区域形成的LER等高线图。基于这些，LER 在明视和中视视觉以及暗视/明视 (S/P) 比率中的功能模型被建立为色度坐标的函数。提出了相应等高线图中 LER 和 S/P 比的增加趋势，这允许快速估计和合成理想的性能。通过使用该函数模型，可以实现理想的三基色光源的 LER、S/P 比及其组合。基于这项工作，
