全光谱照明产品光谱拟合度评估方法研究

Research on Spectral Fitting Evaluation Method of Full-spectrum Lighting Products

照明市场如今已经进入健康照明时代,全光谱照明产品凭借其高显色性和高饱和性、保护视力健康、调节人体昼夜节律、提升学习效率等特点,被认为是健康照明的重要发展方向。本文从光谱功率分布的角度出发,提出了一种评估测试样品光谱和目标光谱接近程度的计算方法,即光谱拟合度系数法,为营造健康光环境评价体系提供了新的思路。本文通过对市面上的全光谱台灯、落地灯的样品进行光谱拟合度测试,结合显色指数指标进行分析,为全光谱照明产品检测提供了参考依据。

The lighting market has now entered the era of healthy lighting.Full-spectrum lighting products are considered as an important development direction of healthy lighting because of their high color rendering and high saturation,protecting vision health,regulating human circadian rhythm and improving learning efficiency.From the point of view of spectral power distribution,this paper puts forward a calculation method for evaluating the similarity between the spectrum of the test sample and the target spectrum,that is the goodness-of-fit coefficient method,which provides a new idea for building a healthy light environment evaluation system.In this paper,the spectral fitting test of the samples of full-spectrum desk lamps and floor lamps in the market is carried out,and the color rendering index is analyzed,which provides a reference for the detection of full-spectrum lighting products.
