This is a comment on a previous Letter [Opt. Lett.35, 3372 (2010)]. The chromaticity coordinates of nanocrystal quantum dot (NQD)-integrated WLED1, WLED2, and WLED3 are out of the range of the chromaticity tolerance quadrangles of white light sources. So these NQD WLEDs do not satisfy the requirements recommended for general lighting with solid-state lighting products to ensure high-quality white light. Furthermore, correlated color temperatures of WLED2 and WLED3 should be 2682 and 2527 K, respectively, according to the chromaticity coordinates of WLED2 and WLED3 at 12 mA, not 2781 and 2390 K. The NQD-integrated WLED1 and WLED2 located in tolerance quadrangles are simulated by the changing spectral power of green-, yellow-, and orange-emitting NQDs. The simulation results are presented.
这是对之前一封信件的评论[Opt. Lett.35, 3372 (2010)]。纳米晶量子点（NQD）集成 WLED1、WLED2 和 WLED3 的色度坐标超出了白光光源色度公差四边形的范围。因此，这些 NQD WLED 不符合推荐用于固态照明产品的一般照明的要求，以确保高质量的白光。此外，根据 WLED2 和 WLED3 在 12 mA 时的色度坐标，WLED2 和 WLED3 的相关色温应分别为 2682 和 2527 K，而不是 2781 和 2390 K。通过改变绿色、黄色和橙色发射 NQD 的光谱功率来模拟位于公差四边形内的 NQD 集成 WLED1 和 WLED2。给出了模拟结果。
