Used for high-precision testing of spatial luminosity distribution (i.e. distribution curve) of various light sources such as LED lamps (semiconductor lighting), road lamps, projection lamps, indoor lamps, outdoor lamps, and LED, energy-saving lamps, fluorescent lamps, incandescent lamps, HID lamps, etc;

The measurement parameters include: spatial light intensity distribution, spatial equivalent light intensity curve, light intensity distribution curve on any cross-sectional area (can be displayed in Cartesian or polar coordinate systems respectively), planar equivalent illuminance distribution curve, brightness limit curve, lamp efficiency, glare level, upper and lower luminous flux ratio, total luminous flux of the lamp, effective luminous flux, utilization coefficient, as well as electrical parameters (power, power factor, voltage, current), etc.

The test results can be exported to various formats such as IESNA (952002) file format (*. ies), CIE file format (*. cie), European Eulumdat (*. ldt) file format, etc., which meet international standard requirements and can be directly used as input data for international lighting design software.
