A goniophotometer measures the variation of luminous intensity with angle from a light source. Goniophotometers are often used to generate “photometric data files” for lighting products in either IESNA (.ies) or EULUMDAT (.ldt) formats. Applications of goniophotometers include the testing of general or architectural lighting products, UVC germicidal lighting, vehicle lighting (headlamp and marker), flashing visual alert devices, road traffic signals, airfield and aircraft lighting. Pro-Lite supplies the photometric test equipment designed and manufactured by SSL Resource Ltd in Salo, Finland. A wide range of goniophotometers is offered that are optimised for different budgets and sample sizes and weights. IES type A, B and C motion goniometer stages are available, with the option of converting certain models between motion types. This inherent flexibility allows one goniophotometer to be used to test both general lighting products and (for example) directional vehicle lighting. Also offered are the SSL LightTester family of turn-key QC stations that provide semi-automated production line testing of the essential photometric, colorimetric, electrical and electrical safety parameters of luminaires.
