- Distributed photometer for measuring light flux is a relatively accurate method, but for different beam angles and different test conditions,it can also bring errors. In this paper, we use the distribution of photometric method to measure luminous flux for different beam angle of the LED under different parameters. By analyzing the experimental data and combining with the light distribution curve, the uncertain factors and their effects in the measurement of LED luminous flux,absolute method are summarized, and the experimental parameters are optimized for different beam angle LED.
