摘要
LED光源目前已在室内照明、室外照明以及非视觉应用方面获得广泛的应用。本文选用了三种不同色温下的太阳光谱作为目标拟合光谱,借助Matlab优化工具箱中的fmincon函数求解了不同目标光谱下各路LED的功率系数组合;提出了一种表征组装光谱与目标光谱的光谱失配评价指数E,并用该指数评价了室内照明常用光源光谱与太阳光谱的相似程度。
As a new light source that has been rising rapidly since 90 s,LED has been widely used in indoor lighting,outdoor lighting and non-visual applications. In this paper,the solar spectra of three different color temperatures are selected as the target fitting spectra. The power coefficients of LEDs are obtained by using the fmincon function in the Matlab optimization toolbox. A spectral mismatch evaluation index E is proposed,and the similarity between the spectra of common light sources and solar spectra is also evaluated by using the index.
