Abstract Using a number of different spectral LED cells, the spectra of several typical spectral light source were fitted successfully. The research focuses on how to find the needed spectral distribution and the least number of LEDs by using the target spectrum to go. Furthermore the result is used to judge and improve the obtained original fitting model. Simulate The target spectrum obtained by the actual measurement was simulated and preferable prospective result was obtained.
