LM-79-19 Compliant Goniophotometer with Rotating Mirror

The LM-79-19 Compliant Goniophotometer with Rotating Mirror, known as the Moving Mirror Goniophotometer, is an advanced automatic light distribution intensity 3D curve testing system. The darkroom can be customized to fit the customer’s existing space. It is capable of measuring various lighting sources, including LED and HID luminaires such as indoor and outdoor fixtures, roadway luminaires, street lamps, flood lights, and other types. The system provides comprehensive measurements including Luminous Intensity Data, Luminous Intensity Distribution, Zonal Luminous Flux, Luminaire Efficiency, Luminance Distribution (optional), 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, among others. Standards adhered to include LM-79-19, EN13032-1, IES LM-80-08, CIE-121, CIE-70, and IES LM-75. Features include a rotary motor sourced from Japan MITSUBISHI MOTORS and an angle decode system from Germany, ensuring smooth rotation and high accuracy. The system is stable during operation and complies fully with LM-80, LM-79, LM-75, GB, EN13032-1, and CIE121-1996 standards. A special collimation device with a laser cross line aids in precise luminaire positioning during testing.
