Product Description
This system uses a fixed detector and rotates the luminaire under test to measure the luminous intensity distribution in all directions of the light source. It is used for high-precision testing of spatial luminous intensity distribution (light distribution curve) of LED luminaires (semiconductor lighting), road luminaires, flood luminaires, indoor luminaires, outdoor luminaires, and various light sources such as LED, energy-saving lamps, fluorescent lamps, incandescent lamps, and HID lamps.
