Description: Goniophotometers are available in a wide range like rotating luminaries, goniophotometers, moving mirror goniophotometers and rotating mirror goniophotometers to achieve measuring way A-a, Bb, Cg. The measurement parameters include spatial intensity distribution, intensity distribution curve of each side (represented by right-angled coordinates or polar coordinates), spatial ISO intensity curve, ISO illuminance distribution curve on the plane, luminance limitation curve, zonal flux, glare grade, luminarie efficiency, effective beam angle, upward and downward luminous flux ratio, total luminious flux, utilisation factor, electric parameters (voltage, current, wattage, power factor) and luminaries for road lighting, room lighting, projecting lighting and reflector lamps. These instruments confirm to the requirement of CIE, IESNA and GB and other international standards.
