摘要

本文提出了一种确定准单色led与白色宽带大功率led在可调相关色温(CCT)照明系统中的最佳峰值波长的新方法。仿真结果表明,该方法可用于合成光参数可调的LED照明系统。该研究能够确定准单色LED(474和600 nm)的峰值波长,当与基本白光LED (Cree CMA 2550)结合使用时,可以控制最宽的CCT范围。具有特定最佳光谱参数的准单色led允许在3098至6712 K的范围内调整CCT,同时在大部分调节范围(3098至5600 K)内保持高显色指数(高于80)。

Determination of optical parameters in quasi-monochromatic LEDs for implementation of lighting systems with tunable correlated color temperature
The paper proposes a new method for determining the optimal peak wavelengths of quasi-monochromatic LEDs, when they are combined with white broadband high-power LEDs in lighting systems with tunable correlated color temperature (CCT). Simulation of the resulting radiation spectrum was used to demonstrate the possibility to use the developed method in LED lighting systems with tunable parameters of the synthesized light. The study enables to determine the peak wavelengths of quasi-monochromatic LEDs (474 and 600 nm), which, when being combined with a basic white LED (Cree CMA 2550), allow controlling the widest CCT range. Quasi-monochromatic LEDs with particular optimal spectral parameters allow adjusting CCT within the range from 3098 up to 6712 K, while maintaining a high color rendering index (higher than 80) over the most part (3098 to 5600 K) of the regulation range.
