Goniophotometer (Light distribution curve)

GPM Serial goniophotometer (Light distribution curve)

Application

It is used to accurately test the light distribution performance of various LED (semiconductor lighting lamps), road lamps, projection lamps, indoor lamps, outdoor lamps, bulb lamps and various photometric parameters of lamps.

System composition

GPM series Goniophotometer, PM series intelligent photometer, WT series digital power meter, WL series high precision DC power supply, CHP series high precision AC power supply, RT200 control unit, light intensity standard lamp, test clamps and light distribution curve software.

Test parameters

Luminous Intensity Distribution Curve, light intensity data, regional luminous flux, lamp efficiency, brightness distribution, Coefficients Of Utilization, brightness limit curve, UGR Table  , Curves of Luminaires vs Lighting Area, Illuminance at a Distance, Field Angle, Beam Angle , Downward Ratio, Upward Ratio, IsoLux Plot, Isocandela and other photometric parameters. With a special spectral analyzer, spatial color characteristic measurement can be realized.
