LSG-1700 goniophotomètre is an automatic goniophotometric instrument for luminous intensity distribution measurement with facility for rotating the light source. It is for industrial laboratory photometric data measurement of luminaires such as LED luminaires, HID luminaires, fluorescent lamps and so on.

Standard :
LM-79-19 "Mesures optiques et électriques des produits d'éclairage à semi-conducteurs".
EN13032-1 "Lumière et éclairage - Mesure et présentation des données photométriques des lampes et des luminaires - Partie 1 : Mesure et format de fichier ; version allemande EN 13032-1:2004+A1:2012"
IES LM-80-08 “Measuring Lumen Maintenance of LED Light Sources”
CIE-121 “The Photometry and Goniophotometry of Luminaires”
CIE-70  “The Measurement of Absolute Luminous Intensity Distribution”
IES LM-75  “GoniophotometerTypes and Photometric Coordinates”

IES file testing Goniophotometer Specification:

• Meets the requirements of CIE-70, IEC, IES LM-79, LM-80, EN13032-1 & GB standards
• Reaching many measurement ways C-Gamma
• The luminaries under test rotates around an angle of (γ)±180°(or 0-360°) and the luminaries rotates around itself with an angle of (C)±180°(or 0-360°)
• Luminosity testing range: Illuminance 0.001lx~10,000lx; Light Intensity 1.0cd～10^7cd (detector)
• The accuracy of angle: 0.2°
• Photometry accuracy: CIE Class 1
• Testing accuracy: 3%(Under Standard lamp); Stray Light: less than 0.2%
• English version software can run on Win7, Win8 or Win10, Win11
