该系统首先给出LED的相对光谱功率分布，据此计算出LED的总光通量等光、色参数。
On basis of the spectrum distribution, we can calculate the optical and colorimeter parameter of LED such as CIE color coordinate, color temperature, color rendering index and so on.
在国家色温基准改造的研究课题中，通过辐射测量法得到了色温副基准灯的相对光谱功率分布，分别运用三种色温计算方法来处理这些数据。
In addition, the relative spectral radiant distribution from the national color temperature standards rebuilding is used to calculate the color temperature of the source in three ways.
