Abstract：As a new light source that has been rising rapidly since 90s,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.
