Product Description

GMS****0 Goniophotometric System is utilized to measure photometric parameters of luminaires for road lighting fixture, room lighting fixture and projecting lighting fixture, such as spatial intensity distribution curve, spatial iso-intensity curve, intensity distribution curve on each section(represent by right-angled coordinates or polar coordinates), iso-illuminance distribution curve on the plain surface, luminance limitation curve, luminaire efficiency, glare grade, effective beam angle, upward luminous flux ratio, downward luminous flux ratio, total luminous flux, effective luminous flux, utilization factor and electric parameters(voltage, current, wattage, power factor) and etc.
