Abstract

The matching of AM1.5 standard solar spectrum in visible light (380-780 nm) with standard light source of CIE-D65 was realized using monochromatic LED

and the matching algorithm of the target spectrum was put forward using active set algorithm. The peak wavelength and FWHM of Epitex's high-power monochromatic LED were used as the effective data set

and a database was established. The maximum correlation index

was used as the optimization objective. The least squares solution of overdetermined equations was solved by MATLAB programming

and the type and quantity of monochromatic LED needed for fitting were obtained. 24 kinds of monochromatic LED are used in the best combination of AM1.5 visible light fitting

and the correlation index

is as high as 0.850 2. 25 kinds of monochromatic LED are used in the best combination of standard light source CIE-D65 fitting

and the correlation index

is as high as 0.940 5. The optimization experiments of increasing and reducing LED numbers were carried out too. The results provide a theoretical basis for the study of monochromatic LED fitting solar spectrum in engineering practice.
