LED Goniophotometer

LED Goniophotometer is suitable for the test of the spatial photometric distribution (light distribution curve) of various light sources and lamps. 

Light source: energy saving halogen lamp, LED, energy saving lamp, fluorescent lamp, incandescent lamp, HID lamp and other light sources; 

Lamps: projection lights, downlights, grille lights, panel lights, street lamps and other indoor and outdoor lighting lamps;

Measurement parameters: light intensity distribution curve, light intensity data, effective luminous angle, beam angle, total luminous flux, regional luminous flux, up-emitting luminous flux, down-emitting luminous flux, lamp efficiency, isoluminance diagram, isoluminance intensity diagram, utilization coefficient, luminance limitation curve, glare level, maximum allowable distance to height ratio, lamp probability curve, UGR unified glare value, effective average illuminance curve, etc.
