中文摘要：

利用多个不同光谱的LED单元成功拟合出几种特征明显的常见标准光源光谱。重点研究了如何通过目标光谱的特性反向找到所需要的LED的频带分布和最小使用的LED数目,进而利用所得结果对原有拟合模型进行条件判别和改进。对一些实测的目标光谱进行了模拟仿真,取得了较为理想的结果。

英文摘要：

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.
