摘要

为解决现有高显色指数发光二极管(LED)光源仍然可能存在富蓝光危害的问题，基于人眼光谱光视效率、辨色函数和光谱响应度函数建立了被测光源光谱与参考光源光谱视觉相似度模型，提出一种以光谱视觉相似度参数(RV)设计高光色品质LED合成照明光源的方法。采用国际照明委员会(CIE)推荐的标准光源D50作为参考光源，将冷白光、暖白光、红色光、绿色光、青色光和蓝色光6种LED组合，通过遍历优化的方法计算各种LED的组合灯珠数量，根据RV＞96的指标要求设计的LED合成光源相关色温范围为4000~7000 K，一般显色指数Ra＞95，符合高光色品质健康照明光源要求，证明了该设计方法的合理性。研究结果还表明，选择不同色温的CIE标准光源作为参考光源，可以设计不同色温要求的高显色性白光。

Abstract

In order to solve the contradiction that light emitting diode (LED) lighting sources with high color rendering index may still exist rich-blue light hazards, the spectral visual similarity model of test light source spectrum with the reference light source spectrum is established based on spectral luminous efficiency, color-resolution function and spectral response function. A method is proposed to design high photometric-colorimetric property LED synthetic light source according to spectral visual similarity parameter (RV). Using the D50, the standard light source recommended by Commission Internationale de L′Eclairage (CIE), as reference illuminant, with the LEDs of cold white, warm white, red, green, cyan and blue are combined. The lamp numbers of all kinds of LED combination are calculated by traverse optimization method. According to the requirement of RV＞96, it turns out that the corresponding color temperature range of LED synthetic light source is between 4000-7000 K, and the general color rendering index Ra＞95 are accordant with the requirements of high photometric-colorimetric property and health in illumination light sources. Which proves the rationality of the proposed method. The results also show that, by choosing CIE standard light source with different color temperatures as the reference illuminant, we can design high color rendering of white light with different color temperatures.
