Goniophotometer is a device used to measure the light distribution performance of lamps. Goniophotometer measures the spatial light intensity distribution of lamps or light sources, total luminous flux and lamp efficiency, and other parameters.
Goniophotometers need to work in a larger darkroom. Our facility at Lighting Laboratory has approximately 188 sq feet of dark room, painted with low-reflectivity material to avoid reflected light from entering the probe. Depending on the arrangement of the measuring light path, two measurement schemes can be used to measure the luminous flux: the illuminance integral method and the luminous intensity integral method.
Our facility has three different types of Goniophotometer which has the ability to measure the illumination distribution pattern from a single LED to lights (tube light/ linear light) up to 4 feet in length.
Measurement: Luminous Intensity Data, Luminous Intensity Distribution, Zonal Luminous Flux, Luminaires Efficiency, Luminance Distribution(Option), Coefficient Of Utilization, Luminance Limitation Curves Glare, Maximum Ratio of Distance to Height, Equal Illuminance Diagrams, Curves of Luminaires VS Lighting Area, Isocandela Diagrams, Efficient Luminescence Angle, EEI, UGR, etc
