摘要：
A facility of spectrogoniophotometer in NIM has been setup, and we make a comparison between the spectrogoniophotometer and a traditional goniophotometer. The differences on total luminous flux measurement are similar to 0.1% for tungsten lamp and similar to 2% for LED (except blue). The facility shows the spectral mismatch correction factor F-star(phi,theta) spatial distribution for common white LED light source is nonuniform and we recommend to introduce this factor to the usage of a traditional goniophotometer for LED light source.
