| Goniophotometer is designed for all kinds of lighting fixture, like floodlights, spotlgithts, dowlights, indoor and outdoor luminaires to measure the spatial luminous intensity distribution curve, section intensity distribution curve, isolux distribution curve, brightness limitation curve, zonal luminous flux, luminous efficiency, glare grades, total luminous flux, efficiency luminous flux, utilization factor and electric parameters. The test can be fulfilled with B-β, A-αand C-γmethods according with different type of lighting fixtures; test principle can completely meet the CIE 70, CIE121 and GB requirements; test process is controlled by software automatically, all the data can display in software and save as EXCEL and PDF files, the most important is that the software can output the IES file to meet the international standard, so that avail to other lighting software. |
