The feasibility of spectral tunable LED-based light source was verified. The source is capable of producing any spectral distribution. According to the measured LED spectral distribution
an asymmetric Gaussian function model was proposed to fit the individual LED spectral distribution. A variety of different LEDs with different peak wavelengths were utilized to synthesize the required spectral distribution. In theory
the least square fitting for any spectrum is realized. The experimental results of synthesis of typical spectral distribution are satisfactory. Finally
based on the analysis of experimental data
this paper put forward some points for the engineering practice.
