...分球能够更好地对光线进行充分积分，对设备的光度和色度性能进行更可靠的测试，测量的单位有：总光谱通量（Total Spectral Flux）、光通量（Luminous Flux）、相对色温（Correlated Color Temperature，CCT）、显色指数（Color Rendering Index ，CRI）和色度（...
On basis of the spectrumdistribution, we can calculate the optical and colorimeter parameter of LED such as CIEcolor coordinate, color temperature, color rendering index and so on.
