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